A Study of Coformulated Favezelimab/Pembrolizumab (MK-4280A) Versus Physician's Choice Chemotherapy in PD-(L)1-refractory, Relapsed or Refractory Classical Hodgkin Lymphoma (MK-4280A-008)

Phase 2
Active, not recruiting
Conditions
Hodgkin Lymphoma
Interventions
Registration Number
NCT05508867
Lead Sponsor
Merck Sharp & Dohme LLC
Brief Summary

Researchers are looking for a way to treat classical Hodgkin lymphoma (cHL) that is relapsed (the cancer has come back after treatment) or refractory (current treatment has stopped working to slow or stop cancer growth). Researchers want to learn if people who receive coformulated favezelimab/pembrolizumab (MK-4280A) live longer without the cancer getting worse compared to those who receive chemotherapy.

  • History of central nervous system (CNS) metastases or active CNS involvement.
  • Has an active autoimmune disease that has required systemic treatment in past 2 years except replacement therapy.
  • History of (noninfectious) pneumonitis/interstitial lung disease that required steroids or has current pneumonitis/interstitial lung disease.
  • Has an active infection requiring systemic treatment.
  • History of hemophagocytic lymphohisticytosis.
  • Has an active seizure disorder that is not well controlled.
  • Has clinically significant (ie, active) cardiovascular disease.
  • Received prior systemic anticancer therapy including investigational agents within 4 weeks before randomization.
  • Received prior radiotherapy within 2 weeks of start of study intervention or radiation related toxicities requiring corticosteroids.
  • Has not adequately recovered from major surgical procedure.
  • Known additional malignancy that is progressing or has required active treatment within the past 3 years.

Favezelimab/Pembrolizumabfavezelimab/pembrolizumabParticipants will receive coformulated favezelimab/pembrolizumab (800 mg/200 mg) by intravenous (IV) infusion on Day 1, then every three weeks (Q3W), for up to 35 infusions.
Chemotherapy (Bendamustine or Gemcitabine)bendamustineParticipants will receive physician's choice of EITHER bendamustine by IV infusion at a dose between 90 and 120 mg/m\^2 on Day 1 and Day 2 of either a 3- or 4-week cycle for up to 6 cycles OR gemcitabine by IV infusion at a dose between 800 and 1200 mg/m\^2 on Day 1 and Day 8 of a 3-week cycle for up to 6 cycles.
Chemotherapy (Bendamustine or Gemcitabine)gemcitabineParticipants will receive physician's choice of EITHER bendamustine by IV infusion at a dose between 90 and 120 mg/m\^2 on Day 1 and Day 2 of either a 3- or 4-week cycle for up to 6 cycles OR gemcitabine by IV infusion at a dose between 800 and 1200 mg/m\^2 on Day 1 and Day 8 of a 3-week cycle for up to 6 cycles.
Primary Outcome Measures
NameTimeMethod
Progression Free Survival (PFS) per Lugano Response Criteria as Assessed by investigatorUp to approximately 39 months

PFS is defined as the time from randomization to the first documented disease progression per Lugano criteria 2014 as assessed by investigator or death due to any cause, whichever occurs first.

Secondary Outcome Measures
NameTimeMethod
Overall Survival (OS)Up to approximately 39 months

OS is defined as the time from randomization to death due to any cause.

Objective Response Rate (ORR) per Lugano Response Criteria as Assessed by investigatorUp to approximately 39 months

ORR is defined as the percentage of participants who achieve a complete response (CR) or partial response (PR) per Lugano criteria 2014 as assessed by investigator.

Duration of Response (DOR) per Lugano Response Criteria as Assessed by investigatorUp to approximately 39 months

For participants who demonstrate CR or PR per Lugano criteria 2014 as assessed by investigator, DOR is defined as the time from the first documented evidence of CR or PR until disease progression or death due to any cause, whichever occurs first.

Number of Participants Who Experienced At Least One Adverse Event (AE)Up to approximately 25 months

An AE is any untoward medical occurrence in a clinical study participant temporally associated with the use of study intervention, whether or not considered related to the study intervention. The number of participants who experience an AE will be presented.

Number of Participants Who Discontinue Study Treatment Due to an Adverse Event (AE)Up to approximately 24 months

An AE is any untoward medical occurrence in a clinical study participant temporally associated with the use of study intervention, whether or not considered related to the study intervention. The number of participants who discontinue study treatment due to an AE will be presented.
