Clinical trial NCT01397825
Conditions: Diffuse Large B-Cell Lymphoma Transformed Follicular Lymphoma Mantle Cell Lymphoma Burkitt's Lymphoma
Sponsor: Millennium Pharmaceuticals, Inc.
Start date: 2011-08-09; Completion date: 2016-10-05
Enrollment: 45 participants; Allocation: NON_RANDOMIZED; Intervention model: PARALLEL

Brief summary:
This is a single-arm, open-label, multicenter, dose escalation, phase 1-2 study of alisertib (MLN8237) administered in patients with relapsed or refractory diffuse large B-cell lymphoma (DLBCL)/transformed follicular lymphoma (TFL) treated with rituximab and vincristine. The study has three parts as follows:

Phase 1, Part 1: Safety lead-in cohort to evaluate alisertib (MLN8237) and rituximab.

Phase 1, Part 2: Dose escalation cohort to evaluate alisertib (MLN8237) + Rituximab + Vincristine and determine Phase 2 dose. Patients with other types of B-cell lymphoma (including mantle cell or Burkitt's lymphoma may enroll in Parts 1 and 2.

Phase 2: Alisertib (MLN8237) + Rituximab + Vincristine in patients with relapsed or refractory DLBCL or TFL at recommended Phase 2 dose.

Note that in 2013 Sponsor decision was taken to not initiate the phase 2 portion of the trial, which would have investigated the triplet at the recommended phase 2 dose identified in part 2. This decision was based on reprioritization within the company and not on any clinical or safety outcomes observed.

Detailed description:
The drug tested in this study was called alisertib. Alisertib was tested to treat people who have relapsed or refractory diffuse large B-cell lymphoma or other aggressive B-cell lymphomas. This study looked at safety, any anti-tumor effect, and it also determined a recommended dose of alisertib plus rituximab and alisertib plus rituximab and vincristine to take into further studies. Pharmacokinetic blood samples were studied to characterize any effects on the concentration of each of the drugs when administered together .

The study enrolled 45 patients. Participants received the following treatments:

Phase 1

* Alisertib 50 mg + rituximab in the Safety Lead-in
* Alisertib 30 mg + rituximab + vincristine in the Dose Escalation
* Alisertib 40 mg + rituximab + vincristine in the Dose Escalation
* Alisertib 50 mg + rituximab + vincristine in the Dose Escalation

All participants were asked to take one alisertib table twice a day for 7 days in each cycle for up to 8 cycles along with rituximab on Day 1 of each cycle; some patients also received vincristine on Day 1 and Day 8 of each cycle. All participants with documented disease response or stabilization could continue with alisertib single-agent therapy for an additional 2 years or more.

This multi-center trial was conducted in the USA. The overall time to participate in this study was up to 5.2 years. Participants made multiple visits to the clinic, plus a final visit 30 days after receiving their last dose of study drug for a follow-up assessment.

Arms: arm 1: Alisertib 50 mg, enteric coated tablets (ECT), orally, twice daily (BID), on Days 1 to 7 followed by a 14-day rest period in 21-day cycles plus rituximab 375 mg/m\^2, intravenous (IV), infusion on Day 1 of each 21-day cycle for up to 8 cycles. Following 8 cycles of treatment (or early discontinuation of rituximab) all participants with documented disease response or stabilization may continue with alisertib single-agent therapy for up to 2 years. arm 2: Alisertib 30 mg, ECT, orally, BID, on Days 1 to 7 followed by a 14-day rest period plus rituximab 375 mg/m\^2, IV, infusion on Day 1, plus vincristine 1.4 mg/m\^2 (max 2 mg), IV, on Days 1 and 8 in a 21-day cycle for up to 8 cycles. Following 8 cycles of treatment (or early discontinuation of rituximab and/ or vincristine) all participants with documented disease response or stabilization may continue with alisertib single-agent therapy for up to 2 years. arm 3: Alisertib 40 mg, ECT, orally, BID, on Days 1 to 7 followed by a 14-day rest period plus rituximab 375 mg/m\^2, IV, infusion on Day 1 plus vincristine 1.4 mg/m\^2, IV (max 2mg), on Days 1 and 8 in a 21-day cycle for up to 8 cycles. Following 8 cycles of treatment (or early discontinuation of rituximab and/ or vincristine) all participants with documented disease response or stabilization may continue with alisertib single-agent therapy for up to 2 years. arm 4: Alisertib 50 mg, ECT, orally, BID, on Days 1 to 7 followed by a 14-day rest period plus rituximab 375 mg/m\^2, IV, infusion on Day 1 plus vincristine 1.4 mg/m\^2, IV (max 2mg), on Days 1 and 8 in a 21-day cycle for up to 8 cycles. Following 8 cycles of treatment (or early discontinuation of rituximab and/ or vincristine) all participants with documented disease response or stabilization may continue with alisertib single-agent therapy for up to 2 years. arm 5: Phase 2: Alisertib (MLN8237) at the Recommended Phase 2 Dose, ECT orally twice/day on Days 1-7 \& rituximab as an IV infusion on Day 1 \& vincristine IV on Days 1 \& 8 in a 21 Day cycle for up to 8 cycles was planned but not conducted.
