NCT06377540

Brief Summary

This is a Phase 2 single arm study to evaluate efficacy and safety of Pembrolizumab before with BEAM ASCT followed by Pembrolizumab maintenance for 1 year. Patients will receive 200 mg Pembrolizumab Q3week starting at day - 28 before stem cell transplant until 1 year after autologous stem cell transplant.

Outcome Measures

Primary Outcomes (1)

  • Progression free survival (PFS)

    Number of participants with progression free survival at 1 year post transplant. Time from date of study enrollment to date of first documented progression, or death. Patients who do not progress or die at the time of analysis will be censored at their last known date alive.

    Baseline to 1 year post-ASCT

Secondary Outcomes (5)

  • Overall survival (OS)

    Baseline to 2 years post-ASCT

  • Progression-free survival (PFS)

    Baseline to 2 years post-ASCT

  • Non-relapse mortality (NRM)

    Day 100 post-ASCT

  • Overall Survival (OS)

    Baseline to 5 year post-ASCT

  • Complete Radiologic Response Rate

    Day 28

Study Arms (1)

Pembrolizumab+BEAM followed by ASCT followed by Pembrolizumab maintenance for 1 year.

EXPERIMENTAL

Patients will receive Pembrolizumab before BEAM ASCT followed by Pembrolizumab maintenance for 1 year. Patients will receive 200 mg Pembrolizumab starting at day - 28 before stem cell transplant until 1 year after autologous stem cell transplant.

Drug: PembrolizumabProcedure: Autologous stem cell transplantDrug: CarmustineDrug: EtoposideDrug: CytarabineDrug: Melphalan

Interventions

Patients will receive 200 mg Pembrolizumab on Day -28 and Day -6 by IV infusion. Pembrolizumab 200 mg IV will resume at day 30+ after ASCT every 3 weeks for 1 year.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Eligible for autologous stem cell transplant (ASCT) with BEAM conditioning regimen
  • KPS greater than 70 or ECOG ≤ 1
  • Adequate organ function and blood counts within 14 days of study registration
  • Participants who are HBsAg positive are eligible if they have received HBV anti-viral therapy for at least 4 weeks, and have undetectable HBV viral load prior to randomization.
  • Participants with a history of HCV infection are eligible if HCV viral load is undetectable at screening.
  • HIV-infected participants must have well-controlled HIV on ART

You may not qualify if:

  • Patients with prior history of any grade 2 or higher autoimmune reaction to PD-1 inhibitors, necessitating permanent discontinuation of the PD-1 inhibitor or necessitating systemic immunosuppressants.
  • Has received prior radiotherapy within 2 weeks of start of study intervention or radiation-related toxicities requiring corticosteroids.
  • Has received a live vaccine or live-attenuated vaccine within 30 days before the first dose of study intervention. Administration of killed vaccines is allowed.
  • Has received any chemotherapy within 3 weeks prior to the first dose of study intervention
  • Has known active CNS disease.
  • History of or active autoimmune disease, or other syndrome that requires systemic steroids or autoimmune agents. Exceptions: Participants with vitiligo, resolved childhood asthma or atopy, hypothyroidism, or Sjogren's syndrome, as well as participants requiring only intranasal steroids, intermittent use of bronchodilators, local steroid injections, or physiologic replacement doses of prednisone (≤ 10 mg/d) may enroll.
  • Has had an allogenic tissue/solid organ transplant.
  • Pregnant or breastfeeding as agents used in this study are Pregnancy Category D (positive evidence of risk). Females of childbearing potential must have a negative pregnancy test (serum or urine) within 14 days of study registration
