Release – Cocrystal Pharma Presentation at ICAR 2026 Highlights Mechanism of Action and Clinical Advancement of CDI-988 for the Prevention and Treatment of Norovirus Infection

Posted on April 30, 2026May 1, 2026 by [email protected]

April 30, 2026

Ongoing Phase 1b human challenge study with oral, direct-acting protease inhibitor is designed to demonstrate proof-of-concept as a preventive and a treatment
Fully enrolled first cohort is assessing the infectivity of the human challenge inoculum
There are no approved treatments or vaccines for norovirus, the leading cause of acute gastroenteritis across all age groups and geographies with a $60 billion annual economic burden
FDA Fast Track designation granted for CDI-988 underscores the lack of approved therapies and seriousness of norovirus infection

BOTHELL, Wash., April 30, 2026 (GLOBE NEWSWIRE) — Cocrystal Pharma, Inc. (Nasdaq: COCP) (“Cocrystal” or the “Company”) announces that the mechanism of action and clinical advancement of its first oral protease inhibitor CDI-988 were featured today in an oral presentation at the 39^th International Conference on Antiviral Research (ICAR 2026) in Prague, Czech Republic. The presentation, titled “First Oral Direct-Acting Antiviral CDI-988 for Norovirus Infection Prevention and Treatment: Novel Mechanism of Action and Phase 1 Study Results,” was delivered by Sam Lee, Ph.D., President and co-CEO of Cocrystal. Presentation slides are available on the Company’s website here.

“It was an honor to share our progress with CDI-988 with the global antiviral research community attending ICAR 2026,” said Dr. Lee. “Following favorable Phase 1 data, we have advanced CDI-988 into a Phase 1b study under a human challenge model that provides an efficient framework to rapidly demonstrate proof of concept as a preventive and as a treatment for norovirus infection. We have now completed enrollment of the stage 1 study cohort, which will establish the infectivity rate of the GII.2 (Snow Mountain Virus) challenge inoculum. This is a critical step in validating infectivity in the study cohorts.

“Multiple norovirus vaccine clinical studies have been initiated over the past decade, yet none have led to an approval in part due to the virus’s extensive genetic variation and drift, spanning 10 genogroups and 49 genotypes,” Dr. Lee added. “CDI-988 is designed to target the highly conserved region of the 3CL protease across all known norovirus strains, including GII.4 and the re-emerging GII.17 variants, as well as all coronaviruses. We believe this compound could offer a much‑needed option for prevention and treatment in a convenient oral formulation that can be readily stockpiled in advance of norovirus outbreaks.”

CDI-988 is a first, oral direct-acting antiviral and was developed using Cocrystal’s proprietary structure-based drug discovery platform technology. As presented by Dr. Lee, in preclinical studies CDI-988 showed favorable gastrointestinal-targeted pharmacokinetics at the site of norovirus infection and also demonstrated potent antiviral activity in GII.4-infected human enteronoid model systems.

In a completed randomized, double‑blind, placebo‑controlled single‑ and multiple‑ascending dose Phase 1 study in healthy adults, CDI‑988 was generally safe and well tolerated across doses up to 1,200 mg, with headache as the most common treatment‑emergent adverse event and no serious adverse events reported. These results, together with a no-observed adverse effect of 1,000 mg/kg in GLP toxicology studies, support CDI-988’s further clinical development in norovirus.

The ongoing Phase 1b randomized, double‑blind, placebo‑controlled challenge study (NCT07198139) is being conducted at Emory University School of Medicine in collaboration with the University of North Carolina. The study is designed to enroll up to 40 healthy adults, ages 18 to 49, in staged cohorts. The stage 1 infectivity cohort, now fully enrolled, will be followed by prevention and treatment cohorts in which CDI‑988 is administered at 1,200 mg twice daily for five days. The primary efficacy endpoint is reduction in the incidence of clinical symptoms, with secondary endpoints including reduction in viral shedding, disease severity, safety and pharmacokinetics.

CDI‑988 has been granted Fast Track designation by the U.S. Food and Drug Administration (FDA) for the treatment and prophylaxis of norovirus infection, underscoring the serious nature of norovirus disease and the lack of approved therapies. Fast Track status is intended to facilitate development and expedite the review of drugs that address unmet medical needs, providing opportunities for more frequent FDA interactions, rolling review of a potential New Drug Application and potential eligibility for Priority Review.

Release – Greenwich LifeSciences Provides Update Regarding Form 10-K Filing

Posted on April 30, 2026April 30, 2026 by [email protected]

Research News and Market Data on GLSI

Download as PDF April 30, 2026 6:00am EDT

STAFFORD, Texas, April 30, 2026 (GLOBE NEWSWIRE) — Greenwich LifeSciences, Inc. (Nasdaq: GLSI) (the “Company”), a clinical-stage biopharmaceutical company focused on its Phase III clinical trial, FLAMINGO-01, which is evaluating Fast Track designated GLSI-100, an immunotherapy to prevent breast cancer recurrences, today provided an update on its Form 10-K filing for the fiscal year ending December 31, 2025.

The Form 10-K for the fiscal year ending December 31, 2025 is still being audited by the auditors who are both trying to reach agreement on the final figures. They have indicated that they expect to complete their audits before the end of May in conjunction with the filing of Form 10-Q for the period ending March 31, 2026.

The final adjustments are focused on accounts payable, which are related to the large global Phase III clinical trial underway and the unexpectedly large increase in screening and patient enrollment in Europe in 2024 and 2025.

As previously announced, the Company’s ending cash balance as of March 31, 2026 is approximately $10.5 million, which is unaudited and is subject to change following the completion of the Company’s financial review for Q1 2026.

About FLAMINGO-01 Open Label Phase III Data

More than 1,300 patients have been screened with a current screen rate of approximately 800 patients per year. The 250 patient non-HLA-A*02 arm is now fully enrolled, where all patients received GLSI-100, which is 5 times more treated patients and recurrence rate data than the approximately 50 patients treated in the Phase IIb trial. The Primary Immunization Series (PIS), which includes the first 6 GLSI-100 injections over the first 6 months and is required to reach peak protection, is followed by 5 booster injections given every 6 months to prolong the immune response, thereby providing longer-term protection.

In the non-HLA-A*02 arm, a preliminary analysis of recurrence rates after the PIS is completed shows an approximately 70-80% reduction in recurrence rate.
This observation is trending similarly to the Phase IIb trial results and hazard ratio where HLA-A*02 patients were treated and where breast cancer recurrences were reduced up to 80% compared to a 20-50% reduction in recurrence rate by other approved products.
The immune response at baseline prior to any GLSI-100 treatment, the increasing immune response during the PIS, and the safety profile of non-HLA-A*02 patients is trending similarly to the HLA-A*02 arms of FLAMINGO-01 and to the Phase IIb study.
- The AACR Meeting 2026 delayed-type-hypersensitivity (DTH) poster can be downloaded here.
- The frequency of DTH reactions increased by approximately 4x (290%) in the total open-label non-HLA-A*02 population, increasing from 5.2% of the patients experiencing a DTH reaction at baseline, prior to any GLSI-100 administration, to 20.4% of the patients experiencing a DTH reaction in month 4 or month 6 (McNemar, p < 0.001).
- As reported in Table 1 of the poster, each HLA-A type exhibited more frequent immune reactivity after treatment with GLSI-100 than at baseline with frequency increasing from 100% to 700%.
- Baseline DTH reaction prior to any treatment suggests that GP2 may be a natural antigen and that GP2 specific T cells may exist in some patients prior to any treatment with GLSI-100. Baseline immune response to GP2 prior to any vaccination with GP2 was also observed in the Phase IIb trial and is being observed in the blinded randomized arms of FLAMINGO-01, where HLA-A*02 only patients are being vaccinated.

Analysis of the open label data from FLAMINGO-01 has been conducted in a manner that maintains the study blind. The open label recurrence rate, immune response, and safety data is based on the patients enrolled to date in FLAMINGO-01 and the data provided by the clinical sites so far, which is not completed or fully reviewed, and is thus preliminary. While comparing any preliminary FLAMINGO-01 data to the Phase IIb clinical trial data may be possible, these preliminary results are not a prediction of future results, and the results at the end of the study may differ.

About GLSI-100 Phase IIb Study

In the prospective, randomized, single-blinded, placebo-controlled, multi-center (16 sites led by MD Anderson Cancer Center) Phase IIb clinical trial of HLA-A*02 breast cancer patients, 46 HER2/neu 3+ over-expressor patients were treated with GLSI-100, and 50 placebo patients were treated with GM-CSF alone. After 5 years of follow-up, there was an 80% or greater reduction in cancer recurrences in the HER2/neu 3+ patients who were treated with GLSI-100, followed, and remained disease free over the first 6 months, which we believe is the time required to reach peak immunity and thus maximum efficacy and protection. The Phase IIb results can be summarized as follows:

80% or greater reduction in metastatic breast cancer recurrence rate over 5 years of follow-up with a peak immune response at 6 months and well-tolerated safety profile.
The PIS elicited a potent immune response as measured by local skin tests and immunological assays.

About FLAMINGO-01 and GLSI-100

FLAMINGO-01 (NCT05232916) is a Phase III clinical trial designed to evaluate the safety and efficacy of Fast Track designated GLSI-100 (GP2 + GM-CSF) in HER2 positive breast cancer patients who had residual disease or high-risk pathologic complete response at surgery and who have completed both neoadjuvant and postoperative adjuvant trastuzumab based treatment. The trial is led by Baylor College of Medicine and currently includes US and European clinical sites from university-based hospitals and academic and cooperative networks with plans to open up to 150 sites globally. In the double-blinded arms of the Phase III trial, approximately 500 HLA-A*02 patients are planned to be randomized to GLSI-100 or placebo, and up to 250 patients of other HLA types are planned to be treated with GLSI-100 in a third arm. The trial has been designed to detect a hazard ratio of 0.3 in invasive breast cancer-free survival, where 28 events will be required. An interim analysis for superiority and futility will be conducted when at least half of those events, 14, have occurred. This sample size provides 80% power if the annual rate of events in placebo-treated subjects is 2.4% or greater.

Release – Cadrenal Therapeutics Announces End-of-Phase 2 Meeting with the FDA and Pivotal Phase 3 Registration Path for CAD-1005 in Heparin-Induced Thrombocytopenia (HIT)

Posted on April 30, 2026April 30, 2026 by [email protected]

Research News and Market Data on CVKD

FDA provided critical guidance for the advancement of CAD-1005 to pivotal Phase 3 in HIT

Phase 2 data showed a greater than 25% absolute reduction in thrombotic events when CAD-1005 was added to standard anticoagulant therapy

PONTE VEDRA, Fla., April 30, 2026 (GLOBE NEWSWIRE) — Cadrenal Therapeutics, Inc. (Nasdaq: CVKD), a biopharmaceutical company developing innovative treatments for life-threatening immune and thrombotic conditions, today announced a major regulatory milestone after successfully completing its End-of-Phase 2 (EOP2) meeting with the U.S. Food and Drug Administration (FDA) and receiving guidance on key elements of the Phase 3 pivotal trial for CAD-1005, the Company’s investigational first-in-class 12-lipoxygenase (12-LOX) inhibitor for heparin-induced thrombocytopenia (HIT).

The meeting with the FDA provided critical guidance on protocol design, study population, dosing, background therapy, exposure, the safety database, and the primary endpoint of new or worsening thrombotic events. After considering FDA feedback on a pivotal registration study, Cadrenal plans to advance directly to a randomized, blinded, placebo-controlled Phase 3 study evaluating CAD-1005 added to the current standard of care for patients with HIT.

“This successful EOP2 meeting marks an important regulatory milestone for Cadrenal and our CAD-1005 program,” said Quang X. Pham, Chairman and Chief Executive Officer of Cadrenal Therapeutics. “Building on our Phase 2 experience with CAD-1005 in HIT and now with FDA guidance for Phase 3, Cadrenal is positioned to pursue a pivotal trial for the first new therapy for HIT in more than two decades.”

Planned Phase 3 HIT Trial Design

Cadrenal’s planned pivotal Phase 3 study – the first randomized, blinded, placebo-controlled registration trial in HIT – will evaluate CAD-1005 in approximately 120 patients across up to 50 clinical centers worldwide and is intended to support a projected NDA submission in 2029. Patients with suspected HIT will be randomized to CAD-1005 or placebo while receiving standard-of-care anticoagulant therapy and treated for up to 14 days during hospitalization. The primary endpoint – centrally adjudicated – is the incidence of new or worsening thrombotic events in patients with Serotonin Release Assay (SRA)-confirmed HIT, with at least one planned interim analysis.

“CAD-1005 is being investigated for the treatment of immune-mediated thrombocytopenia by targeting the underlying pathophysiologic mechanisms that current therapies do not,” said James Ferguson, M.D., Chief Medical Officer of Cadrenal Therapeutics. “Interrupting the vicious cycle of platelet activation in HIT with CAD-1005 could be an important addition to our therapeutic armamentarium for this devastating condition.”

About Heparin-Induced Thrombocytopenia (HIT)

Heparin is the most widely used in-hospital anticoagulant, with more than 12 million patients receiving it in the United States each year. Heparin-induced thrombocytopenia (HIT) is a potentially life-threatening immune-mediated complication of heparin administration that occurs when antibodies to heparin activate platelets, leading to clots throughout the circulatory system, markedly lowering platelet counts, and increasing the risk of bleeding. Complications of HIT include deep vein thrombosis, pulmonary embolism, stroke, myocardial infarction, amputation, and death, with mortality rates for HIT exceeding 20% in some studies. CAD-1005 is the only treatment in clinical development that targets the underlying immune drivers of HIT.

About CAD-1005

CAD-1005 is an investigational therapy under evaluation for the treatment of suspected HIT. CAD-1005 is designed to selectively inhibit 12-LOX, a pathway integral to the primary immune mechanisms that drive HIT. Unlike existing therapies for HIT, which are directed only at preventing thrombotic complications, this approach targets the primary underlying cause of HIT. CAD-1005 has received Orphan Drug Designation (ODD) and Fast Track designation from the U.S. Food and Drug Administration, as well as orphan drug status from the European Medicines Agency.

About Cadrenal Therapeutics, Inc.

Cadrenal Therapeutics, Inc. (Nasdaq: CVKD) is a late-stage biopharmaceutical company advancing novel therapies for life-threatening immune and thrombotic conditions. Its lead program, CAD-1005, is a first-in-class 12-LOX inhibitor for treating heparin-induced thrombocytopenia (HIT), a deadly immune-mediated thrombotic disorder. CAD-1005 has received Orphan Drug and Fast Track designations from the U.S. Food and Drug Administration and orphan drug status from the European Medicines Agency. Second-generation 12-LOX oral therapeutics are also in development for chronic indications.

The Company’s broader pipeline includes tecarfarin, a late-stage oral vitamin K antagonist designed to prevent heart attacks, strokes, and deaths from blood clots in patients requiring chronic anticoagulation, including those with end-stage kidney disease and left ventricular assist devices, and frunexian, a parenteral Factor XIa inhibitor intended for use in acute hospital settings.

Company on track to initiate a randomized, double-blind, placebo-controlled, adaptive Phase 2 field study in the first half of 2027, pending FDA agreement

Phase 2 field study expected to test a two-dose regimen of TNX-4800 subcutaneous with an initial Spring dose followed by a Summer booster two months later; the primary endpoint is Lyme disease prevention for six months

TNX-4800 is expected to provide protection against Lyme disease within two days of the first dose for the peak of the U.S. Lyme season

BERKELEY HEIGHTS, N.J., April 29, 2026 (GLOBE NEWSWIRE) — Tonix Pharmaceuticals Holding Corp. (Nasdaq: TNXP) (“Tonix” or the “Company”), a fully integrated, commercial biotechnology company, announced presentation of Phase 1 data and plans for an adaptive Phase 2 field study of TNX-4800 (formerly known as mAb 2217LS)^1,2 for the prevention of Lyme disease in the U.S., at the 4^th Annual Ticks and Tickborne Diseases Symposium. The Phase 2 study is expected to initiate in the first half of 2027, pending FDA agreement.

The Phase 1 study was conducted by a team at UMass Chan Medical School led by Mark S. Klempner, MD, Professor of Medicine at UMass Chan and an inventor of TNX-4800. The adaptive Phase 2 field study is being planned by Tonix, which licensed TNX-4800 from UMass Chan Medical School in 2025.

TNX-4800 is a long-acting bactericidal (or borreliacidal), human monoclonal antibody (mAb) that targets the outer surface protein A (OspA) of Borrelia burgdorferi, the spirochete bacteria that causes 99.9% of Lyme disease cases in the U.S.^3,4 TNX-4800 was engineered to include a crystallizable fragment (Fc) domain that provides an extended half-life. Tonix is developing TNX-4800 for the prevention of Lyme disease during the U.S. tick season. There are currently no marketed U.S. Food and Drug Administration (FDA)-approved vaccines or prophylactics to protect against Lyme disease.

“We plan to initiate an adaptive Phase 2 field study in the first half of 2027 pending FDA agreement,” said Seth Lederman, MD, Chief Executive Officer of Tonix Pharmaceuticals. “We intend to test a two-dose regimen of TNX-4800, with the first dose administered in the Spring and a second dose administered two months later, for protection against Lyme disease for six months following the initial dose as the primary endpoint. We believe the Phase 1 pharmacokinetic (PK) data support this study design. Each fixed subcutaneous (SC) dose is expected to provide exposures comparable to the 5 mg/kg SC dose evaluated in Phase 1. We have scheduled a meeting with the FDA early in the third quarter of 2026. We look forward to advancing the clinical investigation of TNX-4800 as we strive to overcome the major public health challenges posed by Lyme disease.”

Dr. Lederman continued, “As a long-acting monoclonal antibody that offers passive immunity against the Lyme-causing bacteria within two days, we believe TNX-4800 offers significant advantages over the alum-based combination multi-OspA subunit vaccine in late-stage clinical development. Lyme disease vaccines that elicit antibodies to OspA take more than six months to offer protection and require complex immunization schedules which are obstacles to adherence. A previously approved alum-based OspA subunit vaccine was withdrawn due to poor uptake,⁶ potentially relating to its complex immunization schedule. We believe TNX-4800’s differentiating characteristics could offer meaningful improvements for people seeking protection from Lyme disease.”

Adaptive Phase 2 Field Study Plans
Pending FDA agreement, the Company plans to initiate an adaptive field study in the first half of 2027. The Company plans to study TNX-4800 in a randomized, double-blind, placebo-controlled, adaptive Phase 2 field study to evaluate the efficacy of a two-dose regimen of TNX-4800 SC, in preventing the first occurrence of confirmed Lyme disease during the primary efficacy surveillance period (Day 3 through Month 6 following administration). The two-dose regimen of TNX-4800 was selected for the Phase 2 field study based on the pharmacokinetic results of the Phase 1 study. Each fixed dose is expected to provide exposures comparable to the 5 mg/kg dose evaluated in Phase 1. The first dose will be administered in the Spring and the second booster dose will be administered two months later. Participants will include adolescents and adults 16 years of age and older in Lyme-endemic areas in the U.S. The primary endpoint will be the prevention of Lyme disease for six months (comparison of TNX-4800 group and placebo group) following the initial dose. The Company has scheduled a Type C meeting with the FDA early in the third quarter of 2026 to discuss the planned adaptive Phase 2 field study design.

The Company expects to have Good Manufacturing Practice (GMP) investigational product available for clinical testing in early 2027.

About TNX-4800
TNX-4800 (formerly known as mAb 2217LS) is a long-acting bactericidal, human monoclonal antibody with an engineered extended half-life that targets the outer-surface protein A (OspA) on Lyme-causing Borrelia bacteria. When TNX-4800-containing blood is ingested by the tick, TNX-4800 either kills or blocks the maturation of Borrelia burgdorferi in the mid-gut of infected deer ticks. The Company in-licensed TNX-4800 from UMass Chan Medical School in 2025. Published work in animals showed that TNX-4800 serum levels of at least 21 μg/ml, were approximately 95% effective at preventing infection of non-human primates after six days of exposure to ticks infected with Borrelia burgdorferi.¹^,2 TNX-4800 was derived from mAb 2217 by amino acid substitutions in its Fc domain, which serve to prolong the serum half-life. As a monoclonal antibody, TNX-4800 is designed to provide passive immunity against Lyme disease within two days without relying on the recipient’s immune system to generate antibodies. TNX-4800 also avoids the complex immunization schedules required for an alum-based combination multi-OspA subunit vaccine in development⁷ and the FDA-approved alum-based OspA subunit vaccine that was withdrawn from the market.⁸ TNX-4800 is protected by Issued US Patent US 10,457,721, which is licensed from UMass Chan with expiry in January 2036, excluding any possible Patent Term Extension based on the duration of the clinical trials and the FDA approval process.

TNX-4800 Phase 1 Study Results
TNX-4800 was studied in a randomized, double-blind, sequential dose-escalation study (NCT04863287) that evaluated safety, tolerability, PK, and immunogenicity of TNX-4800 in healthy adults. 44 subjects were randomized, and 41 completed the study. Subjects received a single SC dose of placebo or TNX-4800 at 0.5, 1.5, 5, or 10 mg/kg. Safety was assessed via clinical and lab evaluations. Results showed no significant clinical or laboratory safety signals. All drug-related adverse events were mild or moderate, except for a single severe adverse event that was deemed not drug-related. Drug exposure increased by approximately 25 times for a 20-times increase in dose. Serum TNX-4800 was measurable at the earliest sampling time of two days, indicating rapid systemic absorption. TNX-4800 concentrations remained quantifiable up to 12 months in the majority of participants. At the highest dose of TNX-4800 tested in rats with 1.5-fold higher exposure compared to 10 mg/kg cohort, no adverse toxicity was observed, thus the highest dose tested was considered No Observed Adverse Effect Level (NOAEL). Confirmed anti-drug antibodies (ADSs) were observed transiently in <10% of treated participants, with no impact on PK. TNX-4800 was determined to be generally safe and well tolerated.

About Lyme Disease
In the U.S., Lyme disease is caused by the spirochete bacteria Borrelia burgdorferi. Lyme disease remains the most common vector-borne infection in the United States, and its incidence is climbing each year, due to the expanding the habitat range for ticks.⁸Approximately 87 million people in the United States live, work, or vacation in a tick-endemic area placing them at risk of contracting the disease.⁹ It occurs most commonly in the Northeast, mid-Atlantic, and upper-Midwest regions. Lyme disease bacteria are transmitted through the bite of infected Ixodes ticks. Typical symptoms include fever, headache, fatigue, and a characteristic skin rash called erythema migrans. If left untreated, infection can spread to joints, heart, and nervous system. Laboratory testing is helpful if used correctly and performed with FDA-cleared tests. Although many cases of Lyme disease can be treated successfully with antibiotics, diagnosis and treatment are often delayed or missed. Chronic Lyme is considered an Infection Associated Chronic Illness (IACI), and is a chronic, debilitating disease state characterized by joint and muscle pain, fatigue, and other symptoms.¹⁰

Chiesi Drops $1.9 Billion to Snag KalVista — and the First Oral HAE Treatment on the Market

Posted on April 29, 2026April 29, 2026 by [email protected]

Italian biopharmaceutical group Chiesi has agreed to acquire Nasdaq-listed KalVista Pharmaceuticals (KALV) for $27.00 per share in an all-cash deal valued at approximately $1.9 billion — the company’s largest acquisition in its 90-year history and a major bet on the rare disease space.

For small-cap investors, this is the kind of exit story worth paying attention to. KalVista entered 2026 trading around $15, carried a market cap under $1 billion, and was viewed by many on the Street as an under-the-radar rare disease play. Today, shareholders are looking at a 36% premium to the stock’s 30-day volume-weighted average price — a meaningful payday for those who did their homework on this one early.

What Chiesi Is Really Buying

At the center of the deal is EKTERLY (sebetralstat), a novel plasma kallikrein inhibitor and the first-ever oral, on-demand treatment for hereditary angioedema (HAE) — a rare and potentially life-threatening genetic condition that causes unpredictable episodes of severe tissue swelling. Prior to sebetralstat, patients were largely dependent on injectable therapies to treat attacks, making the oral option a meaningful advancement in disease management.

Since its U.S. launch in July 2025, EKTERLY generated $49 million in global net product revenue through year-end — a strong showing for a first-year rare disease drug in a market that typically takes time to penetrate. The drug is already approved in the U.S., EU, UK, Japan, and several other markets, with a pediatric NDA filing targeting children aged 2-11 planned for Q3 2026.

Strategic Fit and Commercial Ambition

For Chiesi, this isn’t simply a product acquisition — it’s infrastructure. The Italian company has been methodically building out its rare disease unit, Chiesi Global Rare Diseases, and EKTERLY fits squarely into its rare immunology focus. More practically, the deal significantly expands Chiesi’s commercial footprint in the United States, where rare disease market penetration requires both strong science and boots on the ground.

Chiesi has pegged sebetralstat as a meaningful contributor toward its 2030 strategic revenue target of €6 billion — a signal that this asset is expected to carry real commercial weight within the combined organization, not just serve as a pipeline placeholder.

Deal Terms and Timeline

Chiesi will launch a tender offer for all outstanding KALV shares at $27.00 per share. The transaction carries no financing condition and is expected to close in Q3 2026, pending regulatory approvals and at least a majority of shares being tendered. Lazard is advising Chiesi while Centerview Partners is in KalVista’s corner.

The Bigger Picture

The KalVista deal is a reminder of what the small and microcap space consistently delivers — asymmetric outcomes. A company that spent years building a single, differentiated asset in a rare disease niche is now commanding nearly $2 billion from one of Europe’s more acquisitive biopharma groups. As rare disease M&A continues to accelerate driven by major players looking to diversify away from primary care blockbusters, investors with conviction in well-positioned small-cap biotechs may want to keep watching the HAE and broader rare immunology landscape for the next opportunity.

The transaction is expected to close in Q3 2026.

Release – MustGrow to Close NexusBioAg Canadian Distribution Arm to Focus on TerraSante™ Sales Growth in U.S.

Posted on April 28, 2026April 28, 2026 by [email protected]

Research News and Market Data on MGROF

Mar 31, 2026 | News Releases

MustGrow to Close NexusBioAg Canadian Distribution Arm to Focus on TerraSante™ Sales Growth in U.S.

MustGrow is to close its wholly-owned Canadian marketing and distribution business NexusBioAg effective April 15, 2026;
NexusBioAg had been reselling and distributing third party products to Canadian farmers, a lower-margin and price-competitive business;
MustGrow to focus capital and resources on scaling inventory to meet demand for its mustard-derived organic biofertility product TerraSante^TM in the U.S.;
MustGrow is assessing multiple global partnership opportunities to expand TerraSante^TMinternationally;
Preliminary data suggests that TerraSante^TM improves crop yields, soil and soil microbiome health, and nutrient/water use efficiencies.

SASKATOON, Saskatchewan, Canada, March 31, 2026 – MustGrow Biologics Corp. (TSXV: MGRO; OTC: MGROF; FRA: 0C0) (the “Company” or “MustGrow“), announces it is to close its wholly-owned Canadian marketing and distribution business NexusBioAg effective April 15, 2026. NexusBioAg had been re-selling and distributing third party products to Canadian farmers, a lower-margin and price-competitive business. Remaining inventory will be sold in subsequent months through existing distribution channels. MustGrow will focus its capital and resources on scaling inventory to meet accelerating demand for its mustard-derived organic biofertility product TerraSante^TM in the U.S.

TerraSante^TMSales Growth

In 2025, sales demand from large U.S. commercial farmers outstripped MustGrow’s inventory production. MustGrow’s decision to focus on its proprietary TerraSante^TM product in the U.S. requires more focused capital and resources to scale inventory to meet the accelerating demand MustGrow experienced in 2025, and continues to see in 2026.

In January 2026, MustGrow closed a $2 million equity financing, and the proceeds are, in part, being used to build TerraSante^TM inventory to meet growing demand for the product. A $2 million credit facility via CIBC and guaranteed by Canada’s Export Development Canada (EDC) has also strengthened MustGrow’s ability to produce inventory. MustGrow utilizes multiple international third-party manufacturers to produce TerraSante^TM, allowing MustGrow to ramp-up production to meet sales demand, while eliminating the need to build an expensive production plant.

Additionally, MustGrow is assessing multiple global partnership opportunities to expand TerraSante^TM internationally.

TerraSante^TM for Soil and Ecological Health

MustGrow’s mustard-derived TerraSante^TM organic biofertilizer is a wettable powder containing nutritious plant proteins and carbohydrates that feed the soil and soil microbes. TerraSante^TM is currently registered and approved for sale in California, Florida, Arizona, Idaho, Oregon, and Washington State, under Organic OMRI Listed® certification and California’s Organic Input Material (OIM) Program.

MustGrow’s biofertility program focuses on soil and soil microbiome health, nutrient and water use efficiencies, and plant yields. Soil is a farmer’s most valuable asset, and MustGrow’s mustard plant-based technologies are being applied with the intention to improve the health of the soil and soil microbiome, and have a positive impact on root and plant health.

TerraSante^TM contains nutritious plant proteins and carbohydrates that feed the soil and soil microbes, potentially improving beneficial microbial activity and ensuring long-term sustainable soil health. These targeted micro-communities have been shown to work to improve nutrient availability, which can potentially increase plant vigor and yields, while reducing plant stress. TerraSante^TM has the potential to improve crop nutrient uptake and, hence, overall crop performance. There are no artificial additives or preservatives used during its manufacturing.

Eli Lilly (NYSE: LLY) announced today it has entered into a definitive agreement to acquire Ajax Therapeutics, a private biopharmaceutical company developing next-generation JAK inhibitors for patients with myeloproliferative neoplasms (MPNs) — a group of blood cancers that includes myelofibrosis and polycythemia vera. Under the terms of the deal, Ajax shareholders could receive up to $2.3 billion in cash, comprising an upfront payment and additional milestone-based payments tied to clinical and regulatory progress.

The centerpiece of the acquisition is AJ1-11095, an investigational, once-daily oral drug that represents the first-in-class Type II JAK2 inhibitor currently in Phase 1 clinical development. That distinction matters. Every JAK2 inhibitor currently approved for MPNs — including market standards like ruxolitinib — targets the Type I conformation of JAK2. While these treatments offer symptomatic relief, a significant portion of patients eventually lose response or discontinue therapy altogether due to diminishing efficacy.

AJ1-11095 was specifically engineered to address that gap. By binding JAK2 in its inactive Type II conformation, the compound is designed to deliver deeper and more durable disease control — and potentially serve patients who have already failed on existing Type I therapies. Phase 1 dosing began in late 2024, with dose selection for future development expected later this year. First proof-of-concept clinical data is also expected to be presented in 2026.

For Lilly, this isn’t a cold acquisition. The pharma giant was a founding strategic investor in Ajax, meaning today’s deal is less a discovery and more a conviction play — Lilly has seen the science up close and is now moving to own it outright. The transaction builds on Lilly’s established blood cancer capabilities and continues what has been an aggressive dealmaking year for the Indianapolis-based company. Lilly has already announced the acquisitions of Ventyx Biosciences for $1.2 billion and Orna Therapeutics for up to $2.4 billion earlier in 2026.

Lilly’s activity isn’t an outlier — it’s a signal of where the broader market is heading. Biopharma M&A totaled $15.6 billion across 19 deals in Q1 2026 alone, a pace that reflects the structural pressure Big Pharma is operating under. An estimated $236 billion in annual revenue is at risk across the industry from patent expirations of blockbuster drugs, forcing companies to look externally for pipeline replenishment.

Emerging biopharma companies now represent 70% of all clinical-stage assets, with a significant portion remaining unpartnered — and with the IPO market yet to fully recover, many smaller biotech firms are pursuing M&A or partnerships as the most viable path forward. That dynamic creates a fertile hunting ground for acquirers with balance sheet firepower and strategic focus.

The Ajax deal is a textbook example of what is driving this wave: a differentiated mechanism, a validated scientific rationale, an unmet patient need, and a buyer that already understands the asset. For investors watching the small and micro-cap biotech space, the pattern is worth tracking. Companies developing first-in-class mechanisms in high-need therapeutic areas — particularly in oncology and hematology — are drawing premium attention from large-cap acquirers willing to pay up before Phase 3 data is in hand.

The transaction remains subject to customary closing conditions, including Hart-Scott-Rodino antitrust clearance.

Release – GeoVax Highlights Gedeptin® as a Potential Immune-Sensitizing Platform Amid Rising Industry Investment in In Vivo Cancer Therapies

Positioned to Enhance Efficacy of Checkpoint Inhibitors and Next-Generation Oncology Modalities Across Solid Tumors

ATLANTA, GA – April 27, 2026 – GeoVax Labs, Inc. (Nasdaq: GOVX), a clinical-stage biotechnology company developing immunotherapies and vaccines against cancers and infectious diseases, today highlighted the strategic positioning of its oncology asset, Gedeptin® (Ad/PNP), in the context of accelerating industry investment in next-generation in vivo cancer therapies.

Recent high-profile transactions and investments across the biopharmaceutical sector underscore a growing focus on therapies designed to simplify delivery, improve scalability, and expanding therapeutic reach. As these approaches advance, a central challenge remains: many tumors are immunologically “cold,” limiting the effectiveness of even the most advanced therapeutic modalities. GeoVax believes Gedeptin is uniquely positioned to address this challenge.

“While the industry is investing heavily in next-generation cell and gene therapies, the ability to positively modify the local tumor environment is believed to be one of the critical determinants of clinical success,” said David A. Dodd, Chairman and Chief Executive Officer of GeoVax. “Gedeptin is designed to directly destroy both proliferating and non-proliferating tumors, while also demonstrating high bystander activity due to the ability of the in situ generated cytotoxic agent ability to diffuse into neighboring tumor cells.”

Gedeptin is a gene-directed enzyme prodrug therapy (GDEPT), delivered intratumorally, designed to generate PNP, selectively destroy both proliferating and non-proliferating tumor cells within the treated tumor. In vivo preclinical experiments have shown PNP treatment to be additive or synergistic with checkpoint blockade–type agents. For example, studies in preclinical in vivo tumor models of metastasis, have demonstrated treatment of a single lesion can robustly sensitize tumors to checkpoint blockade inhibitors, presumably by destroying tumor tissue (including the tumor microenvironment), exposing neoantigens, and enhancing immune response and activity of immune check point inhibitors (ICIs) at distant PNP-untreated lesions This dual mechanism – localized cytotoxicity combined with enhancing the immune response and activity of immune check point inhibitors against both Gedeptin treated and untreated tumors – has the potential to offer an improved therapeutic approach to addressing solid tumor metastatic disease.

GeoVax has generated preclinical, clinical and translational data supporting Gedeptin’s ability to:

Induce localized tumor cell death against both proliferating and non-proliferating tumors, while minimizing systemic toxicity
Potentially improve response rates when combined with immune checkpoint inhibitors

Aligned with the Next Phase of Immuno-Oncology Innovation

As checkpoint inhibitors continue to move earlier in treatment paradigms, including neoadjuvant and first-line settings, the need for complementary approaches that enhance response rates is becoming increasingly evident.

GeoVax is advancing Gedeptin in combination with checkpoint inhibition in a planned Phase 2 clinical trial in first-line head and neck cancer therapy, with additional solid tumor indications under evaluation.

“Checkpoint inhibitors have transformed cancer care, but many patients still do not achieve durable responses,” said Kelly T. McKee, M.D., Chief Medical Officer of GeoVax. “We believe Gedeptin is well positioned as a combination-enabling platform designed to enhance therapeutic response across checkpoint inhibitors and other emerging oncology modalities.”

About Gedeptin®

Gedeptin® is a gene-directed enzyme prodrug therapy (GDEPT) delivered intratumorally using a non-replicating viral vector encoding purine nucleoside phosphorylase (PNP). Following administration of a systemically delivered prodrug, the encoded enzyme converts the prodrug into a cytotoxic agent directly within the tumor microenvironment. This localized approach is designed to selectively destroy tumor cells while promoting immune recognition and minimizing systemic toxicity. Gedeptin has received Orphan Drug Designation for oral and pharyngeal cancers.

The Company continues to evaluate strategic partnerships and collaborations to advance the clinical development and potential commercialization of Gedeptin-based combination therapies.

Ocugen (OCGN) – Clinical Progress and New Investors Could Sustain Post-Reverse Split Stock Price

Posted on April 27, 2026April 27, 2026 by [email protected]

Monday, April 27, 2026

Robert LeBoyer, Senior Vice President, Equity Research Analyst, Biotechnology, Noble Capital Markets, Inc.

Refer to the full report for the price target, fundamental analysis, and rating.

We Believe The Proposal Is Misunderstood. On April 20, Ocugen filed its proxy statement and Annual Meeting Notice. In addition to the usual business and shareholder matters, there is a proposal to authorize a reverse split. We believe the reverse split could lift the stock to a trading range that meets minimum share price requirements for ownership by more index funds, institutions, and investors.

The Reverse Split Could Open The Stock To More Investors. Ocugen’s three lead clinical programs have reported data that have driven an increase in its market valuation to about $550 to $600 million. However, many index funds, institutions, and brokerage firms have requirements for both minimum share price and market valuation before they can own the stock. We believe the reverse split would help meet these requirements sooner and open the stock to new investors. We expect the stream of clinical milestones in the coming year to sustain the post-split price and drive it higher.
