Citius Pharmaceuticals Receives FDA Response and Guidance to Pre-IND Consultation Submission for Mino-Wrap
-- Mino-Wrap's novel approach to reducing post-mastectomy infections associated with the use of a tissue expander is on track in its preclinical stage
-- Some next steps for Mino-Wrap development include designing and executing a large animal study and the clinical plan
CRANFORD, N.J., Dec. 9, 2020 /PRNewswire/ -- Citius Pharmaceuticals, Inc. ("Citius" or the "Company") (Nasdaq: CTXR), a specialty pharmaceutical company focused on developing and commercializing critical care drug products, announced its receipt of a written response and guidance from the U.S. Food and Drug Administration (FDA) Division of Anti-Infective Products to the Company's Pre-Investigational New Drug (Pre-IND) consultation request for its Mino-Wrap briefing package. Through its global license agreement with the The University of Texas MD Anderson Cancer Center, Citius is developing Mino-Wrap, a novel approach to reducing post-mastectomy infections associated with the use of a tissue expander. The briefing package contained information regarding pre-clinical data and a clinical development plan, along with questions for the FDA regarding safety and efficacy data that would be required to advance Mino-Wrap into clinical trials.
The FDA granted a Written Response Only meeting regarding guidance and direction on the Mino-Wrap development plan. The agency indicated that bio absorption simulation studies may provide information to support the development of Mino-Wrap and made suggestions on what should be provided relative to non-clinical support. The FDA provided guidance on the design of the drug elution studies and agreed that a large animal pharmacology study would be appropriate. They also agreed that a 28-day toxicology study appears appropriate and that microbiology support through existing data is acceptable.
"The FDA provided us with valuable guidance and confirmed a number of our initial plans on the development of Mino-Wrap," said Myron Holubiak, President and CEO of Citius Pharmaceuticals. "We are very pleased to have guidance support from the agency because this is such an under-recognized problem, and current preventative measures have not yielded very acceptable results. We think we have an important innovation for the prevention of post-operative infections associated with breast reconstructive surgery after mastectomies."
Mino-Wrap is a novel approach to reducing post-operative infections associated with surgical implants. Mino-Wrap is a liquefying gel-based wrap containing minocycline and rifampin for reducing tissue expander (TE) infections following breast reconstructive surgeries. It is a laminate film comprised of porcine gelatin plasticized with glycerol. Mino-Wrap also contains the antibiotics minocycline and rifampin to reduce bacterial bioburden on implantable devices preventing colonization over a sustained period of time. In the setting of breast reconstruction, Mino-Wrap is designed to provide more durable antimicrobial protection of the implant-tissue interface than peri-operative irrigation with antibiotic solutions (the current standard of care). Both porcine gelatin (and collagen) as well as the combination of minocycline and rifampin have long histories of successful medical use in implantable devices in multiple anatomical settings.
About Tissue Expanders and Infection Risk
A common breast reconstruction technique is tissue expansion, which involves expansion of the breast skin and muscle using a temporary tissue expander. A tissue expander is an empty breast implant that is filled with normal saline over 6 to 8 weeks until it reaches the breast size that is desired. In this type of reconstruction, the surgeon will either make a pocket under a large muscle in the chest and place a tissue expander in that space or place the expander above the large muscle. About 4 to 8 weeks after the tissue expansion is finished, a second surgery is required to remove the tissue expander and insert the permanent breast implant. The patient receives either microvascular flap reconstruction, or the insertion of a permanent breast implant. Infection is one of the most common complications of tissue expanders and implants during breast reconstruction, with an infection rate ranging from 2.5 to 24 percent.
