Personalized Neoantigen Vaccines through Compassionate Access

The Jaime Leandro Foundation (JLF) is a private nonprofit organization established to deliver breakthrough cancer treatments. We are a unique consortium of experts in cancer, personalized medicine, clinical trials, and vaccines leveraging the FDA’s Expanded Access rule, also known as “compassionate use,” to develop personalized cancer vaccines. Learn more.

For Patients & Families

You or someone you love has been diagnosed with an aggressive form of cancer. Conventional medicine—the “standard of care”—offers little or no hope. We provide new access to treatment options.

For Physicians

You have a patient with a life-threatening condition who might benefit from a personalized vaccine if one could be developed. We can facilitate the process.
