[1] [2] [3] It plans to start public input on October 28. The effort could lead to revised guidance, regulatory changes, staff training or organizational adjustments. [1] [2] Anktiva, used with BCG, is now approved for adults with BCG-unresponsive, high-grade papillary-only bladder cancer that has not invaded the muscle. [4] The UK’s MHRA is updating antidepressant leaflets with clearer warnings about suicidal thoughts and sexual dysfunction that can persist after treatment ends. [5] ## FDA reviews how it regulates rare-disease drugs The FDA’s Rare Disease Framework Initiative will review the agency’s policies, guidance and regulations for rare-disease drugs and biologics. [1] [2] The Rare Disease Innovation Hub is leading the work with the commissioner’s office and the drug and biologics review centers. [1] [2] The agency plans to tailor evidence expectations and advice to each disease, patient group and product, while bringing patients into the process earlier and improving coordination among reviewers. [2] [6] It will also consider risk-based approaches to manufacturing reviews and inspections, along with scientific and statistical methods suited to small populations. [2] [6] The FDA says the effort will retain statutory standards for safety and effectiveness. [2] The FDA plans a public meeting at its White Oak campus on October 28, followed by roundtables, a request for information and internal reviewer sessions. [1] [2] Stakeholder input will shape the framework, which could include new or revised guidance, regulatory changes, training or organizational adjustments, the agency says. [1] [2] The FDA says about 5% of rare conditions have an approved treatment. [1] [3] The agency’s white paper estimates that 30 million Americans live with a rare disease. Small, dispersed populations, limited natural-history data and few validated biomarkers complicate trial design. [2] [7] ## FDA clears Anktiva for papillary-only bladder cancer The FDA expanded Anktiva’s use with BCG to adults with BCG-unresponsive, high-grade papillary-only non-muscle-invasive bladder cancer that has not invaded the muscle. [4] It is the first approved treatment specifically for this group. The FDA acted three months before its original decision date. [4] [8] The decision drew on evidence from Anktiva’s earlier approval for bladder cancer involving carcinoma in situ, as well as clinical and laboratory evidence that the two forms share features. [4] In the earlier trial, 62% of 77 participants had a complete response. Of those responders, 40% maintained it for at least 24 months. [4] The FDA is finalizing guidance on using evidence from carcinoma-in-situ studies to support applications for papillary-only disease. [4] Anktiva is delivered into the bladder through a catheter, initially once a week for six weeks. Treatment can last up to 37 months, depending on response. [4] Its prescribing information warns that delaying bladder-removal surgery may let the cancer spread and become fatal. [4] ## MHRA strengthens antidepressant warnings and patient information The UK’s Medicines and Healthcare products Regulatory Agency is updating antidepressant safety information after patients and families raised concerns about warnings on suicidal thoughts and sexual dysfunction that can continue after treatment. [5] Medicine leaflets will direct readers to information about suicidal thoughts and behaviors. Some will name Post SSRI Sexual Dysfunction as a possible persistent effect. [5] The agency is developing an additional leaflet for people starting antidepressants and those already taking them, with availability planned for 2027. [5] MHRA official Alison Cave said the changes aim to make existing warnings clearer, not discourage treatment. She advised patients to consult a health professional before stopping medication. [5] The UK’s National Institute for Health and Care Excellence will assess whether its published recommendations need revision. [5] ## Also worth knowing - NICE declined to recommend Roche’s breast cancer drug Itovebi. [9] ## The day in numbers - **5%**: Share of rare conditions the FDA says have an approved treatment. [1] [3] - **62% of 77**: Participants in Anktiva’s supporting trial who had a complete response. [4] - **40% at 24 months**: Share of complete responders who maintained their response for at least two years. [4] - **October 28**: Date of the FDA’s planned public meeting on the rare-disease initiative.
