The Grand Challenges family of initiatives fosters innovation to solve key health and development problems. See below for Grand Challenges and related grant opportunities.

Innovations for Gram-Negative Antibiotic Discovery

Initiative
Grand Challenges
Applications Open
Description

The focus of this RFP will be on the discovery of antibiotics with broad spectrum activity against Enterobacteriaceae, using Klebsiella spp. as the pathogen to initiate a discovery program. This provides a common focus point on Klebsiella spp. for all projects in the consortium and facilitates sharing of knowledge and data for mutual benefit. As such, proposals must have a primary focus on Klebsiella spp. but can also include investigation of other Enterobacteriaceae.

Reducing the Burden of Preeclampsia

Initiative
Grand Challenges
Applications Open
Description

We seek proposals for innovative solutions for the early detection, prevention, and treatment of preeclampsia, particularly in low- and middle-income countries where maternal mortality rates are high. To support this focus, we are looking for collaborations, including those with research institutions, health care providers, and global health organizations, that enable cross-sector insights and ensure that solutions are adaptable and practical.

Enhancing HIV and TB Diagnosis: Adjunct Technologies for Sample Collection and Processing

Initiative
Grand Challenges
Applications Open
Description

Recent improvements in diagnostic testing have enabled molecular and lateral flow testing to be performed closer to the patient than ever and in some cases at home with a fully consumable test format. The challenge lies in developing solutions upstream to testing that enable easier, more affordable, and self-administered sample collection, sample preparation, and lysis when needed to support innovative PoC tests with faster turnaround times.

Innovative Data and Modeling Approaches to Measure Women's Health

Initiative
Grand Challenges
Applications Open
Description

Women's health continues to be under-represented and poorly measured in global health frameworks.

Now is the time to address this challenge. Current measurement frameworks, such as the Disability-Adjusted Life Year (DALY), fail to capture the full complexity of women's health outcomes, as they do not account for the multidimensional factors that shape health burdens and progress. These dominant metrics often overlook gendered conditions and social determinants of health, limiting the ability to generate actionable insights. Harmful norms and gender-related discrimination often contribute to poorer health outcomes in women, yet they remain inadequately reflected in existing indicators. Without alternative approaches that incorporate gender-sensitive and multidimensional factors, policies and interventions risk being misaligned with the real needs of women globally. This gap leaves critical gender-related conditions and non-health interventions unmeasured, further hindering progress in advancing women's health.

Accelerating Innovations to Address Heavy Menstrual Bleeding in Women in Low-Resource Settings

Initiative
Grand Challenges
Applications Open
Description

Heavy menstrual bleeding (HMB) affects millions of women globally. Clinically, HMB is defined as excessive menstrual blood loss that negatively affects a woman's physical, emotional, and social well-being. In research settings, HMB is defined as directly measured blood loss exceeding 80 milliliters per menstrual cycle. Many women seek medical attention based on their perceptions of heavy bleeding and its impact on daily life. Abnormal uterine bleeding, of which HMB is a subset, is caused by various factors. Structural abnormalities include polyps, adenomyosis, fibroids, and malignancy, while non-structural factors include bleeding disorders, ovulatory and endometrial dysfunction, and other factors.

Innovations for Exceptionally Low-Cost Monoclonal Antibody (mAb) Manufacturing

Initiative
Grand Challenges
Applications Open
Description

The Gates Foundation and Life Arc are soliciting proposals to develop proofs-of-concept for manufacturing platforms that produce monoclonal antibodies at a final drug substance cost-of-goods of $10 per gram. This Grand Challenge is calling for proposals that are bold in their vision and approach, offering clear pathways to achieving the $10 per gram target. This is not just a technical challenge; it is an opportunity to make a lasting impact on the lives of millions of people worldwide. We invite you to bring your expertise, creativity, and passion to this effort and help shape a future where the best medical treatments are available to everyone, everywhere.
