Orca-T Expanded Access Program Study for Patients With Advanced Hematologic Malignancies

July 22, 2026 updated by: Orca Biosystems, Inc.

An Expanded Access Program for Orca-T Products That Are Out of Specification for Commercial Release

This study is not designed to test a hypothesis; rather, this study will provide patients with access to Orca-T if the commercial Orca-T product produced for them is deemed out of specification (OOS). Serious adverse events (SAEs) occurring during the safety reporting period (defined as the day the recipient receives the Orca-T HSPC drug product through day +365 after transplantation or until initiation of new anticancer therapy, whichever occurs sooner) will be reported.
