What Researchers Found Testing Bevacizumab Plus Erlotinib for Papillary Kidney Cancer

This trial tested bevacizumab plus erlotinib in 83 people with advanced papillary kidney cancer, including the inherited HLRCC form that has no proven treatment. Tumors shrank in 72% of those with HLRCC and 35% of those with sporadic disease.

What the trial was testing

The trial enrolled 83 patients with kidney cancer. The study was sponsored by National Cancer Institute and tracked outcomes across the full group of patients who matched the trial's eligibility profile.

It was initial testing (phase 2). Trials at this stage are designed to produce evidence regulators and physicians can act on — not just observations to follow up later.

What the results showed

72% tumor response rate in inherited HLRCC papillary kidney cancer.

New England Journal of Medicine · 2025 · NCT01130519

These findings — that in inherited HLRCC papillary kidney cancer treated with bevacizumab plus erlotinib — were published in the New England Journal of Medicine and represent the headline result of the study.

Researchers tracked outcomes across 83 patients enrolled in the trial. The result was consistent enough across the group that the team felt confident reporting it.

What this means for patients

For patients with kidney cancer, this result changes the calculus on what to ask their care team about. Whether it changes day-to-day care depends on factors like disease subtype, prior treatments, and where the patient is in their care journey.

What you can do now

Both bevacizumab and erlotinib are FDA-approved for other cancers and available now, though this combination is used off-label for HLRCC papillary kidney cancer. The National Cancer Institute considers it a reasonable option for HLRCC. Ask an oncologist familiar with hereditary kidney cancer for genetic testing and treatment options.

Eligibility for the treatments mentioned above depends on specific test results and clinical history. Bring this summary, the trial name, and your most recent labs or pathology report to your next visit.
