MorphoSys and Vivoryon Therapeutics Enter Agreement on Small Molecule Inhibitors of CD47-SIRP alpha Signaling in Immuno-Oncology

PLANEGG/MUNICH and HALLE/Saale, Germany I July 08, 2019 I MorphoSys AG (FSE: MOR; Prime Standard Segment; MDAX & TecDAX; Nasdaq: MOR) and Vivoryon Therapeutics AG (Euronext Amsterdam: VVY) today announced that they have entered into an agreement under the terms of which MorphoSys has obtained an exclusive option to license Vivoryon's small molecule QPCTL inhibitors in the field of oncology. The option covers worldwide development and commercialization for cancer of Vivoryon's family of inhibitors of the glutaminyl-peptide cyclotransferase-like (QPCTL) protein, including its lead compound PQ912. In exchange, MorphoSys has committed to investing up to EUR 15 million in a minority stake in Vivoryon Therapeutics as part of a capital raise planned for later this year.

While Vivoryon's lead drug candidate PQ912 has already completed a phase 2a clinical trial in Alzheimer's disease, recent preclinical data strongly suggest that the compound could represent a novel approach for cancer therapy. Vivoryon's orally available compounds target the QPCTL enzyme, which has been shown to be a modulator of the CD47-SIRP alpha interaction. Left unchecked, this interaction, known as the "don't eat me" signal, allows cancer cells to escape the body's innate immune defense through inhibition of the phagocytic activity of macrophages. During the option period, MorphoSys will conduct preclinical validation experiments on Vivoryon's family of QPCTL inhibitors, including an assessment of the potential benefits of combining them with MorphoSys's proprietary program tafasitamab (MOR208), which is currently in late-stage development for the treatment of relapsed/refractory diffuse large B-cell lymphoma (r/r DLBCL).

"This deal gives us access to a unique set of drug candidates with exciting potential in cancer", said Dr. Simon Moroney, CEO of MorphoSys. "A number of studies suggests that the CD47-SIRP alpha interaction may be of central importance to the activity of some anti-cancer antibodies. In this regard, securing rights to Vivoryon's estate of compounds in oncology makes strong strategic sense for us. In particular, we are looking forward to exploring the potential for synergy with tafasitamab (MOR208), our most advanced drug candidate. If successful, the use of these orally formulated QPCTL inhibitors may open the way to combinations with other anti-cancer antibodies aiming at boosting their cell killing activity."

"Our small molecule inhibitors represent a novel and innovative therapeutic approach to silence the critical CD47-SIRP alpha checkpoint signal in cancer immunotherapy," said Dr. Ulrich Dauer, CEO of Vivoryon Therapeutics. "As a leading company for antibody and protein technologies with a strong oncology focus, MorphoSys is the ideal partner for us. For Vivoryon this is a strategic alliance to exploit the potential of our first-in-class, highly specific and potent small molecules in combination with therapeutic antibodies for a targeted range of cancer indications. While remaining strongly committed to our development plans in Alzheimer's disease, we are delivering on our strategy to extend the potential of our technology to immuno-oncology."

If MorphoSys chooses to exercise the option, Vivoryon Therapeutics will receive an option fee, and is eligible for milestone payments and royalties.

About Vivoryon Therapeutics AG
Vivoryon Therapeutics AG, Headquartered in Halle (Saale), Germany (Euronext Amsterdam: VVY) is a precision intervention company with an advanced candidate in clinical development focused on bringing first-in-class therapies to patients suffering from age-related diseases. The company has a successful track record in bringing drugs targeted to post-translational modifying enzymes to the market. Current projects are focusing on the two isoenzymes of Glutaminyl cyclase, QPCT and QPCTL. QPCT is the crucial enzyme for the generation of highly neurotoxic pyroglutamate species of Abeta. Its inhibition by Vivoryon's lead molecule PQ912, has successfully completed a phase 2a (SAPHIR) study and the company has initiated a phase 2b core program for the treatment of Alzheimer's disease (AD). QPCTL has been identified as a potential target in cancer therapy. Blocking the enzymatic function of QPCTL by small molecule inhibitors is a novel therapeutic approach to silence the CD47-SIRP alpha signal in cancer immunotherapy. Vivoryon Therapeutics has a unique and exceptionally strong patent position on QPCT and QPCTL inhibitors. www.vivoryon.com
