Soligenix has submitted a Type A Meeting Request to the FDA for discussions on a second Phase 3 study of HyBryte™ (SGX301) for treating cutaneous T-cell lymphoma (CTCL). This follows significant success in the initial Phase 3 FLASH trial, where 16% of patients treated with HyBryte™ showed at least a 50% reduction in lesions compared to 4% for the placebo (p=0.04). The FDA has classified the meeting as high priority, expected within approximately 30 days. HyBryte™ utilizes synthetic hypericin and visible light, posing a safer alternative to conventional treatments by avoiding DNA damage. The company anticipates alignment with the FDA on a pivotal study design to expedite further development of this promising treatment.
Soligenix, Inc. (NASDAQ: SNGX) announced a Type A Meeting with the FDA regarding its NDA for HyBryte™ aimed at treating cutaneous T-cell lymphoma (CTCL). The FDA previously issued a refusal to file (RTF) letter, necessitating positive results from an additional clinical study alongside the Phase 3 FLASH study. Soligenix plans to work closely with the FDA to define the protocol for this new trial. The FLASH study showed statistically significant results, with a 16% response rate for HyBryte™ versus 4% for placebo. HyBryte™ is a photodynamic therapy using synthetic hypericin sodium and has received orphan drug and fast track designations. The additional study requirements mark a setback for the company, but leadership remains committed to advancing the treatment for patients with CTCL.
Soligenix (NASDAQ: SNGX) announced the approval of the nonproprietary name "hypericin sodium" by the USAN Council for its active ingredient in HyBryte™ (SGX301) and SGX302. This novel compound is designed for treating cutaneous T-cell lymphoma (CTCL) and mild-to-moderate psoriasis. In clinical trials, HyBryte™ showed a 58.3% response rate in CTCL and an 80% response in psoriasis. However, an NDA for CTCL is facing an FDA Refusal to File (RTF) due to completeness issues. A Type A meeting with the FDA is scheduled to clarify the RTF concerns. The company continues to pursue further development in psoriasis with SGX302.
