Phase I/II Study of Lenalidomide Plus Pembrolizumab in Patients With Solid Tumors With Expansion in Non-small Cell Lung Cancer

Nonsmall Cell Lung Cancer Clinical Trial

Official title: A Phase I Study of Lenalidomide Plus Pembrolizumab in Patients With Relapsed and/or Refractory Solid Tumors With Phase II Expansion in Non-small Cell Lung Cancer

Status Terminated

Clinical Trial Summary

For the phase I component of the trial a classic 3 + 3 dose escalation design will be utilized, with a fixed dose of pembrolizumab and an escalating dose of the lenalidomide. The patient population will all have histologically confirmed advanced solid tumor malignancy. The primary endpoint for the phase I component of this protocol will be determining the maximum tolerated dose (MTD) of lenalidomide in combination with pembrolizumab.

The phase II component of this trial will utilize a two stage design, initially enrolling 13 patients, followed by 13 more patients if the early stopping criteria are not met. The target population will include patients with histologically confirmed diagnoses of non-small cell lung carcinoma, regardless of histologic subtype; who have completed one line of standard therapy. The primary endpoint for the phase II component of this protocol will be determining efficacy as measured by progression free survival (PFS)

Clinical Trial Description

Phase I The study will plan to enroll 3 patients in an initial cohort, to receive the dose level 1 of lenalidomide (10 mg PO) on days 1-14 of a 21-day cycle, and pembrolizumab (200 mg IV) on day 1. Patients will be evaluated for toxicities after initiation of treatment. If there are no DLTs for the initial 3 patients after one cycle, the next dosing cohort will open, with another 3 patients. Similarly, if the second cohort of patients receives the dose level 2 of lenalidomide (15 mg) for one cycle without DLT, then the third and final cohort will open. When the third cohort testing the dose level 3 of lenalidomide (20 mg) has completed one cycle, the phase I component of the trial will be completed. Standard phase I, 3 + 3 design rules will be utilized as follows: if 1 out of 3 patients experiences a DLT at certain dose level, then 3 more patients will be enrolled at the same level. If 2 out of 6 patients experience DLT at a certain dose level, 3 additional patients are added at the next lower level. Dose reduction is continued until at most 1 of 6 patients experiences DLT. The highest level with at most 1 of 6 patients DLT will be declared MTD. If no dose level achieves this criterion the trial will be discontinued for excess toxicity.

Phase II A pre-treatment (archival) and fresh tumor sample will be needed for participation in trial. PD-L1 expression levels in both samples will be determined to assess the role of chemotherapy on expression level and pattern of this biomarker. Baseline blood samples will be collected for immunologic correlates prior to treatment on Day 1 of Cycle 1 and post treatment at 2, 4, 24 hours. Samples will also be collected prior to treatment on Day 1 of Cycle 2, and at time of progression. Baseline CT scan of the chest and abdomens will be obtained within 30 days prior to the initiation of cycle 1. CT scan with contrast or MRI with contrast of the brain will also be obtained within 30 days prior to the initiation of cycle

1. Time to progression will be measured with disease imaging following every 2 cycles of therapy with a three-day window (+ or -). Patients will continue treatment until disease progression or unacceptable toxicity or two years of therapy. Overall survival will be assessed every 3 months during long term follow up ;
