[{"type":"text","content":"PRINCETON, N.J., July 27, 2022 /PRNewswire/ -- Soligenix, Inc. (Nasdaq: SNGX) (Soligenix or the Company), a late-stage biopharmaceutical company focused on developing and commercializing products to treat rare diseases where there is an unmet medical need, announced today that it has received agreement from the US Food & Drug Administration (FDA) on an initial pediatric study plan (iPSP) for HyBryte™ (synthetic hypericin) for the treatment of cutaneous T-cell lymphoma (CTCL). The agreed iPSP stipulates that Soligenix intends on requesting a full waiver of pediatric studies upon submission of a new drug application (NDA). Agreement with FDA on an iPSP is one of the regulatory requirements that must be met prior to submitting a NDA.\n\n \n \n \n \n \n \n\n \n\"We are pleased to have FDA's agreement on our proposal to request a full waiver of pediatric studies at the time of our HyBryte™ NDA filing later this year,\" stated Christopher J. Schaber, PhD, President & Chief Executive Officer of Soligenix. \"This is consistent with decisions by the European Medicines Agency (EMA) and Medicines and Healthcare products Regulatory Agency (MHRA) in the United Kingdom which have previously granted product-specific waivers from the requirement for pediatric studies in applications for marketing authorization of HyBryte™ in the UK and Europe.\"\nAbout HyBryte™HyBryte™ (research name SGX301) is a novel, first-in-class, photodynamic therapy utilizing safe, visible light for activation. The active ingredient in HyBryte™ is synthetic hypericin, a potent photosensitizer that is topically applied to skin lesions that is taken up by the malignant T-cells, and then activated by visible light 16 to 24 hours later. The use of visible light in the red-yellow spectrum has the advantage of penetrating more deeply into the skin (much more so than ultraviolet light) and therefore potentially treating deeper skin disease and thicker plaques and lesions. This treatment approach avoids the risk of secondary malignancies (including melanoma) inherent with the frequently employed DNA-damaging drugs and other phototherapy that are dependent on ultraviolet exposure. Combined with photoactivation, hypericin has demonstrated significant anti-proliferative effects on activated normal human lymphoid cells and inhibited growth of malignant T-cells isolated from CTCL pat...
