Kintara Therapeutics Granted Fast Track Designation from FDA for REM-001 for Cutaneous Metastatic Breast Cancer

SAN DIEGO, Nov. 28, 2022 /PRNewswire/ -- Kintara Therapeutics, Inc. (Nasdaq: KTRA) ("Kintara" or the "Company"), a biopharmaceutical company focused on the development of new solid tumor cancer therapies, today announced that the United States Food and Drug Administration (FDA) has granted Fast Track Designation (FTD) to Kintara's REM-001 Therapy for the treatment of patients with cutaneous metastatic breast cancer (CMBC).

REM-001 was studied in four Phase 2/3 clinical trials in patients with CMBC who had previously received chemotherapy and/or failed radiation therapy. With clinical efficacy to-date of 80% complete responses of CMBC evaluable lesions, and with an existing robust safety database of approximately 1,100 patients across multiple indications, Kintara is focused on securing the funding necessary to restart a 15-patient study in CMBC patients in advance of a Phase 3 study.

"The receipt of Fast Track Designation represents an important regulatory milestone for our REM-001 Therapy program," said Robert E. Hoffman, President and CEO of Kintara. "We believe this designation is a key component of our future clinical and regulatory strategy as we continue to seek funding, in particular grants, to restart REM-001 clinical development as soon as possible."

Dennis Brown, Ph.D., Chief Scientific Officer of Kintara added, "This designation from the FDA emphasizes the important unmet medical need for safe and effective therapeutic options to address CMBC. We have extensive data in hand to support the advancement of this clinical program and look forward to the continued investigation of our drug candidate in the next study as planned."

Fast Track is a process designed to facilitate the development and expedite the review of drugs to treat serious conditions and fill an unmet medical need. Some of the significant benefits of FTD include:

• Enhanced access to the FDA including opportunities for more frequent meetings and written consultation throughout the remaining development of REM-001.
  
  
• Drugs with FTD are eligible to apply for Accelerated Approval and Priority Review at the time of a New Drug Application (NDA) submission, which may result in faster product approval.
  
  
• FTD also allows for 'rolling review' where Kintara may submit completed sections of the REM-001 NDA as they become available rather than at the end of development.

Located in San Diego, California, Kintara is dedicated to the development of novel cancer therapies for patients with unmet medical needs. Kintara is developing two late-stage, Phase 3-ready therapeutics for clear unmet medical needs with reduced risk development programs. The two programs are VAL-083 for glioblastoma (GBM) and REM-001 Therapy for CMBC.

VAL-083 is a 'first-in-class', small-molecule chemotherapeutic with a novel mechanism of action that has demonstrated clinical activity against a range of cancers, including central nervous system, ovarian and other solid tumors (e.g., NSCLC, bladder cancer, head and neck) in U.S. clinical trials sponsored by the National Cancer Institute (NCI). Based on Kintara's internal research programs and these prior NCI-sponsored clinical studies, Kintara is currently advancing VAL-083 in the Global Coalition for Adaptive Research registrational Phase 2/3 clinical trial titled Glioblastoma Adaptive Global Innovative Learning Environment (GBM AGILE) Study to support the development and commercialization of VAL-083 in GBM.

Kintara also has a proprietary, late-stage photodynamic therapy platform that holds promise as a localized cutaneous, or visceral, tumor treatment as well as in other potential indications. REM-001 Therapy, which consists of the laser light source, the light delivery device, and the REM-001 drug product, has been previously studied in four Phase 2/3 clinical trials in patients with CMBC who had previously received chemotherapy and/or failed radiation therapy. In CMBC, REM-001 has a clinical efficacy to date of 80% complete responses of CMBC evaluable lesions and an existing robust safety database of approximately 1,100 patients across multiple indications. Kintara has paused the REM-001 CMBC program to conserve cash resources.
