Exploring cancer mutations in microgravity: Scientists sent cancer cells to space to study how they age and progress in a unique environment.

(Axios) – UC San Diego scientists are testing a new potential cancer treatment in space. Why it matters: The NASA-funded mission will analyze whether the drug rebecsinib works on ovarian cancer, metastatic breast cancer, leukemia and glioblastoma multiforme (an aggressive … Read More

The Axiom-4 mission will be carrying 'Rebecsinib', the first cancer drug with active US FDA 'Investigational New Drug' (IND) status to be tested in microgravity, marking a significant milestone in space-based pharmaceutical research. Axiom said the experimental cancer treatment, developed by Aspera Biomedicines, targets ADAR1, a gene responsible for cancer cloning and immune evasion. Unlike previous space missions that tested research compounds, Ax-4 will carry a drug already approved for clinical trials on Earth.

Redwire (NYSE: RDW) announced on March 11, 2026 that NASA awarded an additional $4 million to support drug development investigations on the ISS using Redwire’s PIL-BOX technology.The funding expands a task order under a $25 million, five-year IDIQ through NASA’s In Space Production Applications program. PIL-BOX has flown 43 units and supported a cancer therapy investigation for Rebecsinib, an ADAR1 inhibitor, launched on SpaceX Crew-12. Redwire cited collaborations with Aspera, Bristol Myers Squibb, Eli Lilly, ExesaLibero Pharma, Purdue University, and Butler University.
