Note: this is a new type of page for HemOnc.org, as all other regimen pages (except for cancer of unknown primary) are tissue-specific. The initial drug with tissue-agnostic approval is for patients with unresectable or metastatic, microsatellite instability-high (MSI-H) or mismatch repair deficient (dMMR) solid tumors that have progressed following prior treatment and who have no satisfactory alternative treatment options.
