This RFP is jointly launched by several Grand Challenges funding partners, including Grand Challenges Africa (Science for Africa Foundation), Grand Challenges Brazil (Brazilian Ministry of Health and the National Council on Research), Grand Challenges India (Biotechnology Industry Research Assistance Council), Grand Challenges South Africa (South African Medical Research Council), and the Gates Foundation. Each RFP may differ in its geographic focus, topic areas, and funding levels. Please review the eligibility criteria and specific requirements for each RFP carefully. The individual RFPs are listed separately here . If you qualify for more than one, we encourage you to apply to the RFP that best aligns with your proposed project and geographical location.
Local delivery of drugs into the vagina for prevention and treatment of female-specific conditions remains understudied and under-utilized despite clear potential advantages such as discreetness, potent local efficacy, large surface area for drug absorption, high potential for API dosage sparing, potential for fewer systemic side effects, as well as providing autonomy and empowerment of women. Several key drivers may be responsible for this lag, including paucity of mechanistic biological data, particularly from high-burden settings such as low- and middle-income countries (LMICs), to support the development of specific formulations for vaginal use as well as a persistent misconception that vaginally delivered products may not be embraced by women and their sexual partners. Several of our priorities for impactful products for sexual and reproductive health will require vaginal delivery for immediate, on-demand use. We seek to catalyze the development of innovative technologies and approaches that can safely and effectively deliver a wide range of vaginal products. We expect these approaches to have user appeal, including promotion of self-care capability and other beneficial features that women seek, hence the need to couple discovery research with high-quality end-user input.
We are soliciting applications that contribute to development of vaginal formulations that promote optimal drug delivery within the vaginal compartment while positively supporting the vaginal milieu, and that also possess beneficial effects, even if unrelated to the API intended effect, that a user might consider desirable, such as enhancement of sexual pleasure. We anticipate identifying product-agnostic features that promote vaginal health and that broadly appeal to women to advance product development and formulations for women's health. We welcome innovations at any stage of development that meet the scope of this call.
