Brief Summary

This phase II trial studies the effect of polatuzumab vedotin, rituximab, ifosfamide, carboplatin, and etoposide as initial salvage therapy in treating patients with diffuse large B-cell lymphoma that has come back (relapsed) or does not respond to treatment (refractory). Polatuzumab vedotin is a monoclonal antibody, polatuzumab, linked to a toxic agent called vedotin. Polatuzumab attaches to CD79b positive cancer cells in a targeted way and delivers vedotin to kill them. Rituximab is a monoclonal antibody that may interfere with the ability of cancer cells to grow and spread. Chemotherapy drugs, such as ifosfamide, carboplatin, and etoposide, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving chemotherapy with immunotherapy may kill more cancer cells in patients with diffuse large B-cell lymphoma.

Outcome Measures

Primary Outcomes (3)

  • Complete Response (CR) Rate After Two Cycles of PolaR-ICE Salvage Therapy

    Estimated by the proportion of response-evaluable patients achieving CR after 2 cycles of salvage therapy, along with the 95% exact binomial confidence interval. Polatuzumab vedotin (Pola) was added to rituximab, ifosfamide, carboplatin, and etoposide (PolaR-ICE) as salvage therapy.

    After 2 cycles of salvage therapy (each cycle is 21 days)

  • Number of Unacceptable Toxicities of PolaR-ICE Salvage Therapy (Phase 2 Stage)

    Unacceptable toxicity was defined as the events in Section 11.2 occurring during the first 2 cycles of treatment that was at least possibly related to study treatment.

    During the first 2 cycles of PolaR-ICE salvage therapy (each cycle is 21 days)

  • Number of Unacceptable Toxicities of PolaR-ICE Salvage Therapy (Safety lead-in Stage)

    Unacceptable toxicity was defined as the events in Section 11.2 occurring during the first 2 cycles of treatment that was at least possibly related to study treatment.

    During the first 2 cycles of PolaR-ICE salvage therapy (each cycle is 21 days)

Secondary Outcomes (1)

  • Overall Response Rate (ORR) of the PolaR-ICE Salvage Therapy

    From initial treatment to the end of salvage therapy (up to three cycles).

Study Arms (1)

Treatment (PolaR-ICE)

EXPERIMENTAL

SALVAGE THERAPY: Patients receive polatuzumab vedotin IV on day 1, rituximab IV on day 1, etoposide IV on days 1-3, carboplatin IV on day 2, and ifosfamide IV on day 2 or days 1-3. Treatment repeats every 21 days for up to 2-3 cycles in the absence of disease progression or unacceptable toxicity. Patients who achieve complete response, partial response or stable disease by C2D15 may receive 1 additional cycle of PolaR-ICE IV. CONSOLIDATION THERAPY: Within 30-60 days after ASCT, patients receive polatuzumab vedotin IV on day 1. Treatment repeats every 21 days for up to 3-4 cycles in the absence of disease progression or unacceptable toxicity.
