Title: Phase I Dose Escalation Study of MCLA-145, a Bispecific Antibody Targeting CD137 and PD-L1 in Solid Tumors
Poster #: 136P

The e-poster will be available on the virtual platform, in the e-poster section as of Monday, December 6 at 6:00 am ET and on-site at the e-Poster stations starting on Wednesday, December 8. The poster will also be available on the Merus website.

The phase 1, open-label, single-agent clinical trial of MCLA-145 is ongoing. The trial consists of a dose escalation phase, followed by a planned dose expansion phase. MCLA-145 is the first drug candidate co-developed under Merus’ global collaboration and license agreement with Incyte, which permits the development and commercialization of up to 11 bispecific and monospecific antibodies from the Merus Biclonics platform. Merus retains full rights to develop and commercialize MCLA-145, if approved, in the United States; and Incyte holds full rights to develop and commercialize MCLA-145 outside the United States.

About MCLA-145
Discovered through an unbiased functional screening of multiple immunomodulatory target combinations, MCLA-145 is a Biclonics T-cell agonist that binds with high affinity and specificity to human PD-L1 and CD137 in preclinical models. The unique immunostimulatory profile of MCLA-145 derives from the potential to potently activate immune effector cells in the context of the tumor microenvironment while simultaneously blocking inhibitory signals in the same immune cell population.

On December 2, 2021 Onconova Therapeutics, Inc. (NASDAQ: ONTX), a clinical-stage biopharmaceutical company focused on discovering and developing novel products for patients with cancer, reported that early preliminary data from an investigator-initiated Phase 2 open label trial of rigosertib monotherapy in advanced squamous cell carcinoma complicating recessive dystrophic epidermolysis bullosa (RDEB-associated SCC) were presented at the Austrian Society of Dermatology and Venerology Annual Conference 2021, which took place from November 25 – 27, 2021 (Press release, Onconova, DEC 2, 2021, View Source [SID1234596407]).

RDEB is an ultra-rare condition caused by a lack of type VII collagen protein expression. Type VII collagen protein is responsible for anchoring the skin’s inner layer to its outer layer, and its absence leads to extreme skin fragility and chronic wound formation in RDEB patients. Over time, many of these patients develop squamous cell carcinomas (SCCs) that typically arise in areas of chronic skin wounding and inflammation. Preclinical investigations demonstrated overexpression of polo like kinase 1 (PLK1) in RDEB-associated SCC tumor cells. These tumors show a highly aggressive, early metastasizing course, making them the primary cause of death for these patients, with a cumulative risk of death of 70% and 78.7% by age 45 and 55, respectively1,2. These neoplasms show limited response rates of mostly short duration to conventional chemo- and radiotherapy as well as targeted therapy with epidermal growth factor and tyrosine kinase inhibitors1,3.

Data from the recent presentation are from a 24-year-old RDEB patient with a history of multiple, unresectable SCCs that were unresponsive to prior treatments including cemiplimab. Results showed that intravenously administered rigosertib had an acceptable safety profile and that the patient experienced sustained clinical and histological remission of all target lesions without signs of metastatic disease following 13 treatment cycles. The patient remains on study and the trial remains ongoing. The enrollment of additional patients is anticipated at sites in Salzburg, Austria; London, UK; and Philadelphia, Pennsylvania.

"Though the trial’s currently available data are from only a single patient, they represent an exciting and powerful finding that warrants further study," said Andrew South Ph.D., Associate Professor, Department of Dermatology & Cutaneous Biology, Thomas Jefferson University. "RDEB-associated SCC is an indication with an extremely high unmet medical need, as it is invariably fatal with treatment options that have so far yielded disappointing results. The data generated in preclinical models suggesting rigosertib’s robust activity against PLK1 have now been confirmed in the clinic and suggest that rigosertib may play a role in other more common cancers driven by PLK1."

The physicians caring for the patient, Dr. Bauer, Principal Investigator, and Dr. Laimer, Sponsor Medical Expert of the trial, added in a joint statement, "To see a complete response in a patient that has failed multiple prior therapies is highly encouraging and, together with preclinical data, suggests that rigosertib’s ability to inhibit PLK1 may position it as a novel treatment option that can significantly improve upon the current standard-of-care. We look forward to the further evaluation of this hypothesis through the continued advancement of the trial."

A copy of the poster, titled "Rigosertib for locally advanced/metastatic EB-associated SCC," is available on the "Scientific Presentations" section of the Onconova website.

"These data further extend our understanding of MVP-S therapeutic mechanism of action and strongly implicate B cells in the clinical benefit from MVP-S based therapy," said Jeremy Graff, Ph.D., Chief Scientific Officer at IMV Inc.

Oliver Dorigo, M.D., Ph.D., Director and Associate Professor, Division Gynecologic Oncology, Department of Obstetrics and Gynecology at the Stanford University, CA, commented: "Immunotherapies that provoke both a T and B cell response have the potential to provide patients with a new first line therapy for hard-to-treat cancers such as advanced, recurrent ovarian cancer. We are encouraged by the B cell infiltration demonstrated using MVP-S supporting its ability to create a strong immune response in patients who have failed on prior lines of treatment."

Twenty-two women with advanced, recurrent ovarian cancer were enrolled in the DeCidE1 study. In August of this year, IMV announced the completion of the study and shared final top results: Objective Response rates (ORR) of 26.3%, Median Overall Survival of 19.9 months, and a 45% overall survival rate at nearly 2 years. The abstract released today by the ESMO (Free ESMO Whitepaper)-IO congress highlights that:

Enriched B cell infiltration was detected in on-treatment tumor samples, especially in patients who showed tumor reduction; the strongest increase was observed within memory B cells,
The frequency of systemic plasmablasts increased on-study in most of assessed patients and was more pronounced in patients with tumor shrinkage,
Antibodies to all 5 survivin peptides were detected in plasma samples and were more prominent in patients with tumor shrinkage.
These translational data provide new insights into the therapeutic mechanism of action of MVP-S, indicating an important role for B cells in mediating MVP-S induced anti-cancer immunity. The next IMV-sponsored clinical trial in patients with advanced, recurrent ovarian cancer is expected to be initiated in 2022.

The poster will be presented by Oliver Dorigo, M.D., Ph.D., Director and Associate Professor, Division Gynecologic Oncology, Department of Obstetrics and Gynecology at the Stanford University, CA.
