We Turn "Cold" Tumors...HOT!
One Patient’s Story:
A 40-year-old patient diagnosed with Stage III MSS colon cancer, with an 8 cm tumor, received one dose of Botensilimab (BOT) and three doses of Balstilimab (BAL) over seven weeks prior to surgery. This was with no prior or concurrent treatment. The tumor showed significant immune activation and regression, exemplifying the power of BOT/BAL to transform outcomes—even in cancers once considered unresponsive to immunotherapy.

Why BOT/BAL Matters for Patients
Activating the Immune System in Cold Tumors
BOT/BAL is designed to awaken the immune system in “cold” tumors—those previously unresponsive to immunotherapy—bringing the benefits of immune-based treatment to more people with solid tumors.
Real-World Results
-
Over 1,100 patients treated with BOT and BAL
-
Demonstrated clinical benefit in 9 solid tumor types
-
In late-line MSS colorectal cancer, BOT/BAL showed a median overall survival of 21.2 months, compared to 14 months with current standard care
Designed for Safety and Convenience
BOT/BAL’s favorable safety profile allows for treatment even before surgery (neoadjuvant setting), offering new options without the burden of high toxicity.
Backed by the FDA
The BOT/BAL program has received Fast Track designation for third-line MSS colorectal cancer. Discussions are ongoing to align on both accelerated and full approval pathways.
