This $850M Biotech Deal Could Disrupt the Atopic Dermatitis Market

In a strategic move to strengthen its dermatology portfolio, pharmaceutical giant Johnson & Johnson has agreed to acquire Proteologix, a privately-held biotech developing bispecific antibody therapies for inflammatory skin diseases like atopic dermatitis. The $850 million all-cash deal gives J&J access to promising clinical and preclinical stage assets.

The crown jewel of the acquisition is Proteologix’s lead candidate PX128, a Phase 1-ready bispecific antibody targeting two key drivers of atopic dermatitis and asthma – interleukin-13 (IL-13) and thymic stromal lymphopoietin (TSLP). By simultaneously blocking these complementary inflammatory pathways, PX128 could provide a substantial efficacy boost over current monospecific antibody treatments.

Proteologix’s second asset, the preclinical bispecific PX130, goes after IL-13 and IL-22 for the treatment of moderate to severe atopic dermatitis. J&J cited the differentiated design of these dual-acting antibodies, highlighting their potential for infrequent, convenient dosing that could improve adherence.

The acquisition aligns with J&J’s strategic focus on building an immunology pipeline centered around bispecific antibodies for improved disease control across a range of inflammatory conditions.

Atopic dermatitis, a chronic inflammatory skin disease, impacts over 100 million adults worldwide, representing a massive market opportunity. However, up to 70% of patients fail to achieve remission on standard systemic treatments, underscoring a significant unmet need.

“We see an opportunity for best-in-disease efficacy for both PX128 and PX130,” said David Lee, global immunology therapeutic area head at J&J. The company believes the bispecifics could be game-changers for underserved patient subgroups by more comprehensively targeting the heterogenous drivers of atopic dermatitis.

The deal comes on the heels of positive Phase 3 data from Eli Lilly’s IL-13 antibody lebrikizumab in atopic dermatitis. After manufacturing setbacks, Lilly resubmitted its lebrikizumab filing in April and anticipates a decision later this year, setting up a potential commercial clash with J&J’s dual-acting antibodies down the road.

Proteologix, based in California, will be eligible for additional milestone payments on top of the $850 million upfront cash paid by J&J. The transaction, expected to close in mid-2024 pending regulatory approval, will fold in Proteologix’s other preclinical bispecific antibody programs focused on autoimmune diseases and cancer.

For J&J, the deal provides a promising path toward next-generation, differentiated therapies for the significant population of atopic dermatitis patients struggling with existing treatment options. Proteologix’s dual-acting bispecific antibodies represent potentially transformative medicines for a disease area that has proven stubbornly difficult to treat.

The acquisition reinforces J&J’s commitment to immunology and dermatology while bolstering its pipeline with innovative, clinically advanced assets that could drive future growth. As the atopic dermatitis market heats up, J&J has made a preemptive strike to secure a competitive edge through its newest biotech addition.

Incyte Shells Out $750M for Escient’s Immunology Assets

In a move that further solidifies its position in the inflammatory disease space, Incyte Corporation has agreed to acquire Escient Pharmaceuticals for $750 million. The deal, announced on Tuesday, will add two promising immunology and inflammation candidates to Incyte’s pipeline, complementing its existing dermatology portfolio.

The star assets in the acquisition are EP262 and EP547, both of which have shown promising early results in clinical trials. EP262, the more advanced of the two, is currently being evaluated for the treatment of various inflammatory skin conditions, including atopic dermatitis, psoriasis, and vitiligo. Preclinical data has demonstrated EP262’s ability to improve atopic dermatitis-like lesions and reduce inflammation, making it a potentially valuable addition to Incyte’s dermatology lineup.

EP547, while in an earlier stage of development, is being studied for the treatment of itching associated with kidney and liver diseases – a condition known as pruritus, which can significantly impact a patient’s quality of life. With two phase 1 trials currently underway, EP547 could address a significant unmet need in these patient populations.

“EP262 and EP547 are complementary additions to our portfolio, providing an opportunity to leverage our expertise, address the needs of patients with inflammatory diseases and additional potential launch opportunities starting in 2029,” said Hervé Hoppenot, Incyte’s CEO.

For Incyte, the acquisition of Escient Pharmaceuticals represents a strategic move to strengthen its position in the lucrative dermatology market. The company already has an approved JAK1/JAK2 inhibitor cream, Opzelura, which is indicated for atopic dermatitis and vitiligo. With EP262 and additional pipeline candidates, Incyte aims to expand its offerings and capture a larger share of the growing inflammatory skin disease market.

The deal also follows Incyte’s recent acquisition of the cancer drug Monjuvi from MorphoSys, further demonstrating the company’s commitment to bolstering its portfolio through strategic partnerships and acquisitions.

Escient Pharmaceuticals, a relatively young company founded in 2018, had already attracted significant investor interest, raising over $200 million in private financing rounds from the likes of Sanofi. The company’s promising early-stage pipeline and expertise in inflammatory diseases likely made it an attractive target for Incyte.

The transaction, which is expected to close in the third quarter of 2024, will provide Incyte with a diverse range of assets spanning multiple inflammatory and immunological indications. As the company continues to expand its offerings, it remains well-positioned to capitalize on the growing demand for innovative treatments in these therapeutic areas.
