SAN DIEGO--(BUSINESS WIRE)--
Rezafungin designated for the prevention of invasive fungal infections in adults undergoing bone marrow transplantation
Cidara Therapeutics, Inc. (CDTX), a biotechnology company developing novel anti-infectives including immunotherapies, today announced that the U.S. Food and Drug Administration (FDA) has granted both Qualified Infectious Disease Product (QIDP) and Fast Track designations for the company’s prophylaxis (prevention) development program for lead antifungal product candidate, rezafungin for injection. Specifically, the QIDP designation is for the development of rezafungin for the prevention of invasive fungal infections in adults undergoing allogeneic bone marrow transplantation. Cidara previously announced QIDP designation for rezafungin for the treatment of invasive fungal infections caused by Candida.
“This important FDA designation provides significant support for the development of rezafungin in the hematology setting,” said Jeffrey Stein, Ph.D., president and chief executive officer of Cidara. “We now have the opportunity to expedite the development of rezafungin to address significant unmet needs both in the prevention of invasive fungal infections in immunocompromised patients undergoing bone marrow transplantation, as well as for the treatment of patients with existing severe invasive fungal infections.”
Cidara is developing rezafungin, a novel antifungal echinocandin, as a once-weekly, high-exposure therapy for the treatment and prevention of serious invasive fungal infections. Rezafungin is being studied to address unmet needs in the treatment of candidemia and invasive candidiasis as well as for prophylaxis of invasive fungal infections due to common fungal pathogens: Candida, Aspergillus and Pneumocystis. No one agent is approved today to prevent infections caused by these pathogens and current prophylaxis regimens often require multiple antifungal drugs with safety and tolerability issues. Cidara plans to commence the Phase 3 ReSPECT prophylaxis clinical trial of rezafungin in patients undergoing allogeneic bone marrow transplantation in the first quarter of 2019.
The QIDP designation, provided under the Generating Antibiotic Incentives Now Act (GAIN Act), offers certain incentives for the development of new antifungal and antibacterial drugs, including Fast Track, priority review and, if rezafungin is ultimately approved by the FDA, eligibility for an additional five years of marketing exclusivity. Fast Track designation enables more frequent interactions with the FDA review team to expedite drug development.
To achieve QIDP designation, a drug candidate must be intended to treat serious or life-threatening infections, particularly those caused by bacteria and fungi that are resistant to treatment, or that treat qualifying resistant pathogens identified by the FDA. These listed qualified pathogens include Candida and Aspergillus species, which have the potential to pose a serious threat to public health.
About Invasive Fungal Infections
Approximately 97,000 Americans die from hospital-related invasive fungal infections each year and 90 percent of these infections are caused by two common fungi, Candida and Aspergillus. Pneumocystis Pneumonia (PCP) is another serious fungal infection that commonly afflicts people with weakened immune systems. Systemic fungal infections typically affect patients whose immune systems have been compromised, such as patients undergoing organ or bone marrow transplantation or chemotherapy, including patients with hematologic malignancies, or patients in intensive care units and those with prolonged hospital stays.
About Cidara Therapeutics
Cidara is a clinical-stage biotechnology company focused on developing new anti-infectives that have the potential to transform the standard of care and save or improve patients’ lives. The company is currently advancing its novel echinocandin antifungal, rezafungin acetate, formerly known as CD101 IV, through clinical trials. Rezafungin has improved pharmacokinetics compared to existing echinocandins and the potential for expanded utility across patient settings. It is the only once-weekly product candidate in development for the treatment and prevention of life-threatening invasive fungal infections. The company’s Phase 2 STRIVE clinical trial of rezafungin met its primary safety and efficacy objectives, and provides support for Cidara to initiate Phase 3 pivotal trials in the treatment of candidemia and invasive candidiasis and the prophylaxis of invasive fungal infections. Cidara is also leveraging its novel Cloudbreak™ platform to develop antibody-drug conjugates for the treatment of serious viral and Gram-negative bacterial infections. Cloudbreak is the first immunotherapy discovery platform designed specifically to create compounds that directly kill pathogens and also direct a patient’s immune cells to attack and eliminate bacterial, fungal or viral pathogens. Cidara is headquartered in San Diego, California. For more information, please visit www.cidara.com.
