Jazz Prescription drugs’ pipeline has oncology bets sprinkled all through, however nothing in most cancers immunotherapy. The corporate is popping to Werewolf Therapeutics to fill that hole, hanging a deal to get a cytokine remedy that’s on the trail to scientific testing.
In accordance with monetary phrases introduced Thursday, Dublin-based Jazz is paying $15 million up entrance for world rights to Werewolf drug WTX-613. Milestone funds might convey Werewolf, based mostly in Cambridge, Massachusetts, as much as $1.26 billion. If Jazz is ready to commercialize its new asset, it might pay Werewolf royalties on the drug’s gross sales.
Cytokines are signaling proteins that may spark an immune response. Engineered variations of those proteins have been used for many years as most cancers remedies. Nonetheless, as these medication flow into by means of the physique, they spark an immune response that goes past most cancers cells—a poisonous impact that limits their use. Cytokine therapies additionally don’t have a long-lasting therapeutic impact. Werewolf and different biotech firms have been engineering a brand new era of cytokine therapies meant to supply a safer and more practical immune response.
The Werewolf platform know-how, referred to as Predator, engineers a cytokine in a method that shields it from binding to something till it reaches a tumor. The remedy can be designed to have an extended half-life, overcoming the sturdiness problems with earlier cytokine therapies. WTX-613 is an engineered model of a cytokine referred to as interferon alpha.
Final December, Werewolf introduced promising preclinical knowledge for its model of interferon alpha through the annual assembly of the American Society of Hematology. In a mouse mannequin for blood most cancers, Werewolf reported that its drug stopped tumor development and activated responses from two kinds of immune cells, pure killer cells and CD8+ cells. The corporate additionally reported that the drug confirmed an prolonged half-life in comparison with native interferon alpha.
With the encouraging preclinical knowledge in hand, Werewolf deliberate to submit an investigational new drug software with the FDA in 2023. That timeline remains to be intact, however Jazz now plans to make that FDA submitting.
“This transaction underscores our dedication to enhancing our pipeline to ship novel oncology therapies to sufferers, and likewise gives us with a possibility to develop into immuno-oncology,” Rob Iannone, government vp, world head of analysis and improvement of Jazz Prescription drugs stated in a ready assertion.
For Werewolf, the Jazz deal means the biotech can preserve its give attention to its lead packages. WTX-124 is an engineered model of a cytokine referred to as interleukin-2, whereas WTX-330 is Werewolf’s model of interleukin-12. The biotech stated it expects to file investigational new drug purposes for each packages later this yr.
There’s loads of cytokine competitors going through each Jazz and Werewolf. Final November, the FDA authorised Besremi, an interferon alpha drug that PharmaEssentia drug developed for polycythemia, a uncommon blood most cancers. Asher Bio emerged from stealth final yr with know-how for engineering a greater, probably extra focused model of IL-2. Xilio Therapeutics goals to enhance on cytokine security with a “masks” that stays on the remedy till it reaches the tumor microenvironment. That firm’s IL-2 program is on observe for an investigational new drug software this yr.
In the meantime, Avenge Bio is taking a cell remedy method to cytokines. The corporate contends that human IL-2 might have benefits over engineered variations. Its method employs immune cells engineered to supply IL-2. These cells are implanted on the tumor web site to localize the immunotherapy’s impact.
