Study Details

Brief summary:

Patients will receive one of two conditioning regimens (BEAM or CBV) before receiving an autologous stem cell transplant (ASCT). If patients achieve either complete, partial, or stable response following ASCT, they will receive an IV dose of Polatuzumab Vedotin once every 21 days until they receive 8 doses. After Polatuzumab Vedotin therapy is completed, patients will be followed every 4 months for about 2 years.

Interventions and Outcome Measures

Arms

experimental: Polatuzumab vedotin

Evaluable patients for safety Patients receiving 1 dose of Polatuzumab Vedotin will be evaluable for safety.

Evaluable patients for response Only in patients who are in PR or SD prior to PV and received a minimum of 3 doses will be evaluable.

Evaluable patients for EFS, PFS, OS All patients who have completed conditioning and autoSCT will be evaluable for EFS, PFS, and OS.

Interventions

Polatuzumab vedotin

All patients will receive a myeloablative conditioning regimens (BEAM or CBV, as selected by the treating physician) followed by autologous stem cell transplant (ASCT). All patients on this study will receive an autologous stem cell transplant (ASCT) on Day 0 followed by supportive care including the drugs sargarmostim and filgrastim until blood counts are stable. If a complete, partial, or stable response is achieved following ASCT, the patient will receive an IV dose of Polatuzumab Vedotin once every 21 days until he/she receives 8 doses.

Primary outcome measure

  • Safety and tolerability [ Time Frame: 1 year ]
