The event will feature Rahul Aggarwal, M.D. (University of California San Francisco), who will discuss the unmet need and evolving treatment landscape for prostate cancer, as well as the clinical development program for FG-3246* (also known as FOR46), a CD46 targeting antibody-drug conjugate (ADC) with first-in-class potential for the treatment of metastatic castration-resistant prostate cancer (mCRPC). The initiation of a Phase 2 monotherapy trial in mCRPC is expected in the second half of 2024.

The event will additionally review data from the Phase 1b/2 study evaluating FG-3246 in combination with enzalutamide in mCRPC presented at the 2024 American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) meeting.

A live question and answer session will follow the formal presentation.

This series is intended for investor audiences only.

About Rahul Aggarwal, MD
Rahul Aggarwal, MD is a Professor of Medicine and Thomas Perkins Distinguished Professor of Cancer Research at the University of California San Francisco. He is the Associate Director for Clinical Research in the UCSF Helen Diller Family Comprehensive Cancer Center and the Program Leader for the Genitourinary Oncology program. He specializes in translational and clinical research in prostate cancer, with a particular emphasis on the development of novel therapeutic and imaging modalities for men with advanced prostate cancer.

About FG-3246
FG-3246 (FOR46) is a potential first-in-class fully human antibody-drug conjugate (ADC), exclusively in-licensed from Fortis Therapeutics, and is being developed by FibroGen for metastatic castration-resistant prostate cancer and potentially other tumor types. FG-3246 binds to an epitope of CD46, a cell receptor target, that induces internalization upon antibody binding, is present at high levels in prostate cancer and other tumor types and demonstrates very limited expression in most normal tissues. FG-3246 is comprised of an anti-CD46 antibody, YS5, linked to the anti-mitotic agent, MMAE, which is a clinically and commercially validated ADC payload. FG-3246 has demonstrated anti-tumor activity in both preclinical and clinical studies. FG-3246 is currently in an ongoing Phase 1b/2 study being conducted at UCSF as an investigator-sponsored trial to evaluate FG-3246 in combination with enzalutamide. An additional investigator-sponsored radiopharmaceutical marker trial using a zirconium-89 positron emission tomography (PET) tracer for CD46 that utilizes the YS5 antibody is also underway at UCSF. The initiation of the Phase 2 monotherapy trial in metastatic castration-resistant prostate cancer is anticipated in the second half of 2024. FG-3246 is an investigational drug and not approved for marketing by any regulatory authority.

Day One Expands Pipeline with Potential First-in-Class Clinical-Stage Antibody Drug Conjugate (ADC) Targeting PTK7 in Solid Tumors for Adult and Pediatric Cancers

On June 18, 2024 Day One Biopharmaceuticals (Nasdaq: DAWN) ("Day One" or the "Company"), a commercial-stage biopharmaceutical company dedicated to developing and commercializing targeted therapies for people of all ages with life-threatening diseases, reported it has entered into an exclusive licensing agreement (the Agreement) with MabCare Therapeutics (MabCare) for MTX-13, a novel ADC targeting protein-tyrosine kinase 7 (PTK7) (Press release, Day One, JUN 18, 2024, View Source [SID1234644421]). Pursuant to the terms of the Agreement, Day One has exclusive rights to develop, manufacture, and commercialize MTX-13 worldwide, excluding Greater China.

In April 2024, the U.S. Food and Drug Administration (FDA) cleared the investigational new drug (IND) application for MTX-13, which going forward will be identified as DAY301. In pre-clinical studies, DAY301 showed antitumor activity in a wide range of solid tumors.

"Our priorities for 2024 are to successfully launch OJEMDATM (tovorafenib), to advance our existing programs and to expand our pipeline by in-licensing clinical-stage assets that have the potential to transform outcomes for patients of all ages living with cancers," said Jeremy Bender, Ph.D., chief executive officer of Day One. "We are excited by the opportunity presented by DAY301, and we believe we have the right team in place to develop the program to its full potential."

DAY301 targets PTK7, a highly-conserved, catalytically inactive transmembrane protein that is overexpressed in multiple adult cancers, including esophageal, ovarian, lung, and endometrial cancer, as well as pediatric cancers such as neuroblastoma, rhabdomyosarcoma and osteosarcoma. PTK7 has limited expression in normal tissues or organs, making it an attractive target for therapeutic development.

"The addition of DAY301 to our pipeline strategically fits our mission of advancing both pediatric and adult medicines in areas of unmet need with equal urgency," said Dr. Samuel Blackman, co-founder and head of research and development at Day One. "We believe the linker-payload technology embodied in DAY301 will overcome the limitations of earlier PTK7-targeted ADCs, giving us a potential first-in-class drug against a clinically-validated target. We are excited to add this program to Day One and will look to enter the clinic in the coming months."

Under the terms of the licensing agreement, MabCare will receive $55 million upfront, and is eligible to receive an additional $1.152 billion in development, regulatory and commercial success-based milestones, plus low-to-mid single-digit royalties on net sales outside of Greater China. Day One expects the first patient to be dosed in the Phase I study in the fourth quarter of 2024 or first quarter of 2025.

The FDA has shared with MediLink concerns that BNT326/YL202 may, at higher doses, expose human subjects to unreasonable and significant risk of illness or injuries. In order to address the FDA requests, certain steps need to be taken, including reviewing clinical and safety data, sharing available pharmacological data with the Agency and providing additional information in the investigators brochure regarding the safety findings including grade 5 adverse events observed in studies YL202-INT-101-01 and YL202-CN-201-01. MediLink has taken actions to pause enrollment of new patients in the U.S. and address the FDA requirements.

First Quarter 2024 Financial Results

Cash Position: Cash and cash equivalents were $0.4 million as of March 31, 2024, as compared to $0.8 million as of December 31, 2023. Subsequent to March 31, 2024, our cash and cash equivalents have decreased to approximately $0.2 million as of May 31, 2024. Subsequent to May 31, 2024, the Company received a $0.7 million loan from DGP Co., Ltd., a significant stockholder. The loan has a maturity of ten months from issuance and interest at a rate of 6.0% per annum is payable at maturity. The Company believes that its cash and cash equivalents are insufficient to continue to fund operations and additional funding is needed in the very near term.

Revenue: On February 5, 2024, the Company entered into a patent license agreement to develop cavrotolimod for potential treatment for hepatitis with a private clinical stage biopharmaceutical company. Under the terms of the agreement, this biopharmaceutical company will receive an exclusive license in the field of hepatitis to all of the Company’s relevant patents. An initial payment of $0.5 million was paid to the Company after the execution of this agreement. The Company will also be entitled to modest royalties on future net sales of all licensed technology during the term of the licensed patents.

Research and Development (R&D) Expense: Research and development expenses were $0 for the quarter ended March 31, 2024, as compared to $1.4 million for the quarter ended March 31, 2023. The decrease in R&D expense for the three months ended March 31, 2024 of $1.4 million reflects the stoppage of clinical, preclinical, and discovery program activities and a reduction in employee headcount with lower employee-related expenses and fewer discovery, preclinical, and clinical program activities resulting from the restructuring activities that the Company announced in December 2021 and September 2022.

General and Administrative (G&A) Expense: General and administrative expenses were $1.3 million for the quarter ended March 31, 2024, as compared to $3.1 million for the quarter ended March 31, 2023. The decrease in G&A expense of $1.8 million for the three months ended March 31, 2024 was mostly due to lower compensation and related payroll costs, professional fees, and operating costs as a result of reduced operations.

Net Loss: The Company had a net loss of $0.8 million for the quarter ended March 31, 2024, as compared to a net loss of $4.4 million for the quarter ended March 31, 2023. The decrease in net loss of $3.6 million was primarily driven by the reduction of payroll and operating costs due to reduced operations, as well as $0.5 million of revenue as a result of a license agreement payment received during the quarter.

Going Concern: Management believes that the Company’s existing cash and cash equivalents is not sufficient to continue to fund operations. The Company has already engaged in significant cost reductions, so our ability to further cut costs and extend the Company’s operating runway is limited. As a result, substantial additional financing is needed in very near term to pay expenses, fund the ongoing exploration of strategic alternatives and pursue any alternatives that may be identified. The Company needs to raise capital to fund its operations. There can be no assurance that such additional financing will be available and, if available, can be obtained on acceptable terms.
