NCT04323956

Brief Summary

This phase I/Ib trial studies the side effects and best dose of parsaclisib with or without polatuzumab-vedotin (Pola) plus the standard drug therapy (rituximab, cyclophosphamide, doxorubicin hydrochloride, vincristine sulfate, and prednisone \[PaR-CHOP\]) and to see how well they work compared with R-CHOP alone in treating patients with newly diagnosed, high risk diffuse large B-cell lymphoma. Parsaclisib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Rituximab is a monoclonal antibody that may interfere with the ability of cancer cells to grow and spread. Polatuzumab-vedotin is a monoclonal antibody, called polatuzumab, linked to a chemotherapy drug, called vedotin. Polatuzumab is a form of targeted therapy because it attaches to specific molecules (receptors) on the surface of cancer cells, known as anti-CD79b receptors, and delivers vedotin to kill them. Drugs used in chemotherapy, such as cyclophosphamide, doxorubicin hydrochloride, and vincristine sulfate, 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. Anti-inflammatory drugs, such as prednisone, lower the body's immune response and are used with other drugs in the treatment of some types of cancer. It is not yet known if giving parsaclisib and R-CHOP together works better than R-CHOP alone in treating patients with high risk diffuse large B-cell lymphoma.

Outcome Measures

Primary Outcomes (2)

  • Maximum tolerated dose (MTD) of parsaclisib in combination with rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) (Phase I)

    The MTD will be defined as the dose level below the lowest dose that induces dose-limiting toxicity in in at least one-third of patients (at least 2 of a maximum of 6 patients).

    Up to 21 days

  • Complete metabolic response (CMR) rate (Dose Expansion)

    Will be measured by positron emission tomography (PET). A success is defined as an objective status of CMR by the PET-computed tomography (CT) based response criteria at the end of treatment. The proportion of successes will be estimated by the number of successes divided by the total number of evaluable patients. Exact binomial 95% confidence intervals for the true rate of complete metabolic response will be calculated.

    Up to end of treatment (3-4 weeks after day 1 of cycle 6 [each cycle is 21 days])

Secondary Outcomes (12)

  • Incidence of adverse events (AEs) (Phase I)

    Up to 2 years

  • Incidence of toxicity due to parsaclisib in combination with Pola-R-CHP (Pola Safety Lead-in)

    Up to cycle 1 (21 days)

  • Objective response rate (Dose Expansion)

    Up to end of treatment (3-4 weeks after day 1 of cycle 6 [each cycle is 21 days])

  • Duration of response (Dose Expansion)

    Up to 2 years

  • Event-free survival (Dose Expansion)

    Up to 5 years

  • +7 more secondary outcomes
