On January 12, 2021 Medivir AB (publ) (Nasdaq Stockholm: MVIR) reported that it has entered into an exclusive licensing agreement, through which IGM Biosciences, Inc. (Nasdaq: IGMS), will receive global, exclusive development rights for birinapant, a clinical-stage SMAC mimetic that binds to and degrades Inhibitors of Apoptosis Proteins (IAPs), leading to cell death (apoptosis) in tumor cells (Press release, Medivir, JAN 12, 2021, View Source [SID1234573855]). The combination of IGM-8444, an IgM antibody targeting Death Receptor 5 (DR5) being developed by IGM, and birinapant has been shown to enhance anti-tumor activity preclinically. Medivir will receive an upfront payment of USD 1 million upon signing the agreement, followed by an additional USD 1.5 million when birinapant is included by IGM in clinical phase I studies. The terms of the agreement furthermore entitle Medivir, should birinapant be successfully developed and approved, to receive milestone payments up to a total of approximately USD 350 million, plus tiered royalties up to mid-teens on net sales.

– "Agreements, such as the one announced today with IGM, continue to be a core component of Medivir’s corporate mission and business model," said Yilmaz Mahshid, Chief Executive Officer of Medivir. "Today’s announcement further exemplifies our focus and commitment to the development and commercialization of innovative treatments for cancer, and we look forward to IGM’s progress with birinapant in the clinic and beyond."
– "Based on our in vitro and in vivo models, which have shown remarkable synergy between IGM-8444 and birinapant, we are excited to explore this combination’s potential to deliver superior anti-tumor activity in patients with solid tumors," said Fred Schwarzer, Chief Executive Officer of IGM Biosciences. "This agreement is part of a broader strategy to realize the full potential of our IgM drug candidates by maintaining control over the timing and development path of the more promising combinations to emerge from our preclinical and clinical work. We look forward to moving the IGM-8444-birinapant combination into clinical testing to begin validating the significance of targeting DR5 with an IgM antibody in certain combinations and to continuing to explore similar strategic options across our IgM platform."
In addition to its apoptotic activity, birinapant augments anti-tumor immune system activity. Through this double action, on both tumor cells and cells of the immune system, birinapant has the potential to improve the treatment of several types of cancer when used in combination with other drugs. IGM-8444 is currently being tested in a phase I dose escalation study in patients with solid and hematologic malignancies. DR5 is a member of the tumor necrosis factor receptor superfamily (TNFRSF) and is often expressed on the surface of cancer cells. Subject to regulatory review, IGM hopes to begin the clinical testing of birinapant in combination with IGM-8444 for the treatment of solid cancers later this year.

About birinapant
Birinapant is a SMAC mimetic that was acquired from TetraLogic Pharmaceuticals Corporation (TetraLogic) in 2016 and has since then been developed by Medivir. Medivir recently renegotiated the original agreement with TetraLogic so that the compensation Medivir is obliged to pay in connection with a licensing agreement is based on the distribution of actual future revenues to Medivir.
