Manhattan BioSolutions, Inc. Enters into License Option Agreement with Wisconsin Alumni Research Foundation (WARF) for the RNA Nuclease Technology

On May 15, 2023 Manhattan BioSolutions, Inc. ("Manhattan Bio"), an emerging biotechnology company developing new classes of precision biologics for the treatment of advanced cancers, reported that it has entered into an exclusive option agreement with the Wisconsin Alumni Research Foundation (WARF) for the innovative pan-RNA degrader technologies (pRNAD) in oncology (Press release, Manhattan BioSolutions, MAY 15, 2023, View Source [SID1234631728]). The exclusive option agreement involves the intellectual property rights to technology developed in the laboratory of Ronald T. Raines at the University of Wisconsin-Madison.

Ronald T. Raines, Ph.D., is currently the Roger and Georges Firmenich Professor of Natural Products Chemistry at the Massachusetts Institute of Technology (MIT), an Extramural Member of the Koch Institute for Integrative Cancer Research at MIT, and an Associate Member of the Broad Institute of MIT and Harvard. Professor Raines has also joined Manhattan Bio’s Board of Directors.

The pRNAD technology is based on an engineered derivative of a naturally occurring nuclease protein involved in host defense to selectively degrade RNA in both tumors and their microenvironment. In preclinical studies, pRNAD has shown a favorable tolerability profile and potent single agent activity against a variety of cancer models such as ovarian, prostate, non-small cell lung and colon cancers. The lead drug candidate has been previously evaluated in a Phase 1 human clinical trial conducted in patients with advanced refractory solid tumors, showing promising results.

Dr Borys Shor, Chairman and CEO, Manhattan Bio, commented: "We are excited to announce this agreement and associated data acquisition, which adds potentially first-in-class clinic-ready program to our pipeline of differentiated biologics. This agent was designed to specifically target and disrupt key vulnerabilities in tumors, including their dependence on extracellular RNA and hyperactive RNA metabolic pathways. Our strategy has been to build a portfolio of world-class development candidates through a combination of in-licensing or in-house discovery. The RNAD transaction is in line with this vision."

Pending completion of the investigational new drug (IND) application process and subsequent regulatory activation of the IND, Manhattan Bio plans to initiate a phase 1b clinical trial in selected tumor indications. The company is also advancing innovative technologies capable of potentially generating multiple Investigational New Drug Applications (INDs), including novel linker/payload technologies for antibody-drug conjugates.

· Announced completion of enrollment in Part A of the DeFiance Study of DKN-01 for the treatment of colorectal cancer patients. The DeFianCe study (NCT05480306) is a Phase 2, randomized, open-label, multicenter study of DKN-01 in combination with standard of care bevacizumab and chemotherapy in patients with advanced CRC who have received one prior systemic therapy for advanced disease. The study began with an initial Part A cohort that has enrolled 33 patients and is designed to expand into a 130-patient Part B randomized controlled trial. The primary objective is progression free survival. Secondary objectives include overall response rate, duration of response, and overall survival. Leap expects to report initial data from Part A of the study in mid-2023.

Selected First Quarter 2023 Financial Results

Net Loss was $41.9 million for the first quarter 2023, compared to $10.4 million for the same period in 2022. The increase was primarily due to in-process research & development (IPR&D) expense of $29.6 million associated with the acquisition of Flame Biosciences.

Research and development expenses were $38.9 million for the first quarter 2023, compared to $7.8 million for the same period in 2022. The increase in research and development expenses was due to IPR&D expense associated with the Flame acquisition of $29.6 million, increased headcount and compensation expense of $0.8 million, increased manufacturing costs of $0.8 million, increased stock based compensation expense of $0.1 million, partially offset by decreased clinical trial costs of $0.2 million.

General and administrative expenses were $3.8 million for the first quarter 2023, compared to $2.8 million for the same period in 2022. The increase in general and administrative expenses was due to increased finance and legal fees, primarily associated with the Flame acquisition, of $0.7 million and increased headcount and compensation expense of $0.3 million.

Cash and cash equivalents totaled $102.0 million at March 31, 2023. Research and development incentive receivables totaled $2.3 million at March 31, 2023.

ANKET is Innate’s proprietary platform for developing next-generation, multi-specific natural killer (NK) cell engagers to treat certain types of cancer. This fit-for-purpose technology is creating an entirely new class of molecules to induce synthetic immunity against cancer. Innate’s latest innovation, the tetra-specific ANKET, is the first NK cell engager technology to engage activating receptors (NKp46 and CD16), a tumor antigen and the interleukin-2 receptor (via a non-alpha IL-2 variant, IL-2v) via a single molecule. By providing proliferation and activation signals targeted to NK cells, tetra-specific ANKET leverages the advantages of harnessing NK cell effector functions against cancer cells.

IPH6501, the first tetra-specific ANKET, continues toward a Phase 1 clinical trial in 2023.
