For Physicians
Precision Oncology Starts Here: Fast, Personalized Guidance for Complex Cases
First Ascent provides real-world insights supporting oncologists in identifying the next right step in treatment planning, improving outcomes, reducing costs and mitigating side effects.
For oncologists caring for patients who have exhausted standard therapies, First Ascent provides all the data and analysis needed to help select the right combination of FDA-approved agents that best target the patient’s cancer.
Functional Precision Medicine with Validated Clinical Impact
First Ascent Biomedical delivers AI-powered clinical decision support through a proprietary xDRIVE platform—supporting oncologists in identifying the most effective therapies for cancer patients, especially those with refractory or treatment-resistant cancers.
By testing how live cancer cells respond to up to 150+ FDA-approved therapies and combinations, xDRIVE provides patient-specific evidence on how an individual’s cancer responds in an average of 10 days. A fresh biopsy sample is all it takes to unlock the evidence-based path forward for even the most challenging cases.
How It Works

Collect a liquid or solid, core or needle fresh biopsy sample

Live cancer cells are tested ex vivo against a panel of FDA-approved therapies and combinations

Physicians receive a precise report with patient-specific evidence on how the cancer responds to drugs an average of 10 days
Published, Proven, Patient-Centered
In a prospective clinical study published in Nature Medicine:
83% of patients received new, viable treatment options
8.5x median improvement in progression-free survival
Reports were delivered in an average of 10 days
