On August 16, 2016 Accurexa Inc. (the "Company" or "Accurexa") (ACXA), a biotechnology company focused on the development of novel neurological therapies to be directly delivered into the brain reported that it received a written response from the FDA (U.S. Food and Drug Administration) regarding a pre-IND (Investigational New Drug) meeting request for its ACX-31 program for the local delivery of temozolomide as adjunctive therapy to BCNU, both chemotherapeutics, in the treatment of brain tumors in conjunction with surgery and radiation (Press release, Accurexa, AUG 16, 2016, View Source [SID1234516522]). The FDA confirmed the acceptability of a 505(b)(2) application pathway with one first-in-human Phase 2 clinical trial followed by one Phase 3 clinical trial.

Key Points of Written Response:
Acceptability of a 505(b)(2) application pathway confirmed
Pharmacology studies appear adequate
Non-clinical studies appear adequate with the exception of one GLP-compliant toxicology study in a single animal species using the route and schedule of administration proposed for the planned Phase 2 trial to be required
Phase 2 clinical trial strongly recommended to be conducted in patients with relapsed/recurrent glioblastoma
Proposed Phase 2 trial primary endpoints appear adequate
If an adequately designed Phase 2 trial demonstrates tolerability and suggests activity, FDA would encourage Accurexa to request an End-of-Phase 2 meeting to discuss the design of an adequate and well-controlled, randomized Phase 3 trial
"We are very pleased with the outcome of the FDA meeting. The FDA’s acceptance of a 505(b)(2) application pathway reduces the cost and time for the development of our ACX-31 Brain Cancer program than it would otherwise require. The FDA provided valuable guidance and we continue moving our ACX-31 program forward towards clinical development," said George Yu, MD, Accurexa’s President & CEO.
Under a 505(b)(2) application pathway the Company can rely on studies of previously approved drugs that were not conducted by the Company. The benefits of a 505(b)(2) application include lower risk due previous drug approvals, lower cost and accelerated development due to fewer studies, than a typical new drug application.
