ClinConnect Summary

This clinical trial is looking at a combination of two drugs, lenvatinib and pembrolizumab, to see if they can help patients with anal or rectal cancer that has worsened after standard treatments. The aim is to understand how safe and effective this new treatment is for patients whose cancer has spread and is no longer responding to regular therapies. The trial is not yet recruiting participants, but it will include adults aged 18 and older of all genders.

To participate, patients must have a specific type of cancer confirmed by a medical test and show that their disease is measurable. They should also be in reasonably good health, without any active infections or certain other serious health conditions. Participants will need to give their consent and will be closely monitored during the trial to track their progress and any side effects. This study represents an important step in exploring new treatments for patients facing challenging cancer situations, and it aims to provide hope for better outcomes.

• • Has radiographic evidence of encasement or invasion of a major blood vessel, or of intratumoral cavitation. Note: the degree of proximity to major blood vessels should be considered because of the potential risk of severe hemorrhage associated with tumor shrinkage/necrosis following lenvatinib therapy.
