RedHill Biopharma announces FDA clearance for Phase III study with RHB-102 RedHill Biopharma announced that the FDA has allowed the initiation of the company's planned Phase III clinical study for the treatment of a new, undisclosed indication with RHB-102, an extended release oral pill formulation of the antiemetic drug ondansetron. RedHill plans to begin enrolling patients for the Phase III study during Q3. The double-blind placebo-controlled Phase III study is planned to be conducted in eight clinical sites in the U.S. and will include 320 subjects. Based on prior discussions with the FDA and the UK Medicines and Healthcare Products Regulatory Agency, or MHRA, the study is intended to support potential future submissions of marketing applications for a new undisclosed indication in both the U.S. and Europe. RedHill estimates that, if the Phase III clinical study is successful and the marketing applications are filed and approved by the FDA and the MHRA, the new indication would significantly expand the potential market for RHB-102. In parallel to pursuing the new undisclosed indication, RedHill is pursuing marketing approval of RHB-102 for the indications of chemotherapy and radiotherapy-induced nausea and vomiting in Europe and the U.S.
