Trial Outcomes & Findings for Pilot Study of Pembrolizumab Treatment for Disease Relapse After Allogeneic Stem Cell Transplantation (NCT NCT02981914)

NCT ID: NCT02981914

Last Updated: 2024-04-22

Results Overview

A DLT is defined as the development of grade 3 or 4 acute GVHD (defined by the Gluckenberg scale), graft rejection, the development of any unexpected grade \> 2 toxicity felt to be related to pembrolizumab, or the development of \> grade 2 dysfunction of a vital organ felt to be secondary to an immune-related adverse event within 90 days following the initiation of pembrolizumab treatment.

Measure
Pembrolizumab
Pembrolizumab will be administered at a fixed dose of 200 mg IV every 3 weeks. Treatment will be administered for up to 24 months, provided that neither disease progression, nor development of a dose-limiting toxicity (DLT), has occurred. Pembrolizumab: Pembrolizumab will be administered at a fixed dose of 200 mg IV every 3 weeks for a max of 24 months, so long as there is no disease progression.

Pembrolizumab: Pembrolizumab will be administered at a fixed dose of 200 mg IV every 3 weeks for a max of 24 months, so long as there is no disease progression.
Number of Patients With Dose-limiting Toxicities (DLTs)
3 Participants

SECONDARY outcome

Timeframe: From date of response until the date of first documented progression or relapse, whichever came first, assessed up to 12 months

Population: Note: one patient censored at 54 days, second patient had disease progression at 364 days. Per the area under the Kaplan-Meier curve, the mean would be estimated as 364 days. However this estimate is unreliable given that it is based on only one censored observation and one event. The censored observation has been omitted in the full range below, as "54+" is rejected as a valid entry.

To determine the duration of response (DOR) of patients treated with pembrolizumab in the setting of relapsed myeloid malignancies and mature B cell lymphomas following alloSCT.

Time Between Initial Response and Subsequent Disease Progression or Relapse
364 days
Interval 364.0 to 364.0

SECONDARY outcome

Timeframe: 24 months

Population: The trial enrolled 8 AML patients, 3 lymphoma patients, and 1 MDS patient. Both responders were lymphoma patients.

For B cell lymphoma patients, partial and complete responses will be defined according to the International Working Group criteria. For MDS patients, partial and complete responses (including cytogenetic responses) will be defined according to the International Working Group criteria. Lastly, for AML patients, complete (including CR, CRp, CRi), and partial responses will be defined according to the European Leukemia Net response criteria.
