Registration Number
NCT03743766
Lead Sponsor
John Kirkwood
Brief Summary

The main goal of this study is to evaluate the antitumor activity of relatlimab and nivolumab in combination in subjects with unresectable or metastatic melanoma who have not received prior treatment with immunotherapy.

Detailed Description

This study will evaluate the antitumor activity of anti-LAG3 monoclonal antibody relatlimab and the anti-PD1 monoclonal antibody nivolumab in combination in subjects with unresectable or metastatic melanoma who have not received prior treatment with immunotherapy. The trial is designed with a lead-in phase of 2 cycles (4 week) treatment of either nivolumab, relatlimab, or the combination of nivolumab/relatlimab, followed by a combination phase of nivolumab/relatlimab treatment in all subjects. This lead-in design with accompanying tumor biopsies and peripheral blood analyses will enable mechanistic analyses of the effect of LAG3 and PD1 blockade alone and in combination to enhance understanding of mechanisms of response and resistance. Duration of response, progression free survival, and safety will be assessed as secondary objectives.

Exclusion Criteria
  • Known or suspected CNS metastases, with the following exceptions:

    • Subjects with controlled brain metastases will be allowed to enroll. Controlled brain metastases are defined as no radiographic progression for at least 4 weeks following radiation and/or surgical treatment at the time of consent. Subjects must be off steroids for at least 2 weeks prior to randomization.
    • Subjects with signs or symptoms of brain metastases are not eligible unless brain metastases are ruled out by computed tomography or magnetic resonance imaging.
  • Active autoimmune disease requiring treatment, with the exception of type 1 diabetes mellitus, vitiligo, resolved childhood asthma/atopy, controlled hyper/hypothyroidism, hypoadrenalism or hypopituitarism.

  • Prior adjuvant treatment with anti-PD1, anti-PDL1, and/or anti-LAG3 antibody. Note that prior adjuvant treatment with targeted therapy (e.g. BRAF/MEK inhibition), anti-CTLA4, or treatment not otherwise specified above would be permitted.

GroupInterventionDescription
Relatlimab + NivolumabRelatlimab + NivolumabCycle 1+: Combination therapy will be administered by sequential infusion. Nivolumab administered at 480 mg IV followed by infusion of relatlimab at 160 mg IV for the first 4 weeks (Cycle 1), then once every 4 weeks afterwards.
NivolumabNivolumabCycle 1: Nivolumab (BMS-936558) is supplied as a sterile 10-mg/mL formulation to be administered as an IV infusion at 480 mg IV for the first 4 weeks. Cycle 2+: Combination therapy will be administered by sequential infusion. Nivolumab administered at 480 mg IV followed by infusion of relatlimab at 160 mg IV once every 4 weeks.
RelatlimabRelatlimabCycle 1: Relatlimab (BMS-986016) is supplied as a sterile 10mg/mL formulation to be administered as an intravenous (IV) infusion at 160 mg IV for the first 4 weeks (cycle 1). Cycle 2+: Combination therapy will be administered by sequential infusion. Nivolumab administered at 480 mg IV followed by infusion of relatlimab at 160 mg IV once every 4 weeks.
Primary Outcome Measures
NameTimeMethod
Change in LAG3 ExpressionAt baseline and at 4 weeks

LAG3 (cell surface molecule expressed on activated T cells) expression is either positive (present) or not detectable if absent after completion of lead-in phase.

Change in PD1 expressionAt baseline and at 4 weeks

PD1 (programmed cell death protein 1) expression is either positive (present) or not detectable if absent after completion of lead-in phase

Change in Tumor SizeAt baseline and at 4 weeks

Tumor size will be assessed per Response Evaluation Criteria in Solid Tumors. Per RECIST 1.1, Tumour lesions: Must be accurately measured in at least one dimension (longest diameter in the plane of measurement is to be recorded) with a minimum size of:

* 10 mm by CT scan (CT scan slice thickness no greater than 5 mm; see Appendix II on imaging guidance).

* 10 mm caliper measurement by clinical exam (lesions which cannot be accurately measured with calipers should be recorded as non-measurable).

* 20 mm by chest X-ray.

Overall Response Rate (ORR)Beginning at 12 weeks post initial treatment, up to 4 years

Number of participants experiencing Complete Response (CR) + Number of participants experiencing Partial Response (PR)/total patients assessed. Per RECIST v1.1, CR: Disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to \<10 mm. PR: At least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters. PD: At least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study (this includes the baseline sum if that is the smallest on study). In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm. (Note: the appearance of one or more new lesions is also considered progression). SD: Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD, taking as reference the smallest sum diameters while on study.

Secondary Outcome Measures
NameTimeMethod
Duration of Response12 weeks post initial treatment, up to 4 years

Time from first documented Complete Response (CR) or Partial Response (PR) until the first date that progressive disease is objectively documented. Per RECIST v1.1, CR: Disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to \<10 mm. PR: At least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters.

Clinical Benefit Rate12 weeks post initial treatment, up to 4 years

Complete Response (CR) + Partial Response (PR) + Stable Disease (SD) / total patients assessed per RECIST v1.1. CR: Disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to \<10 mm. PR: At least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters; SD: Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD, taking as reference the smallest sum diameters while on study.

Progression-free Survival (PFS)Up to 4 years

Progression-free survival is defined as the time between the date of randomization and the first date of documented progression or death due to any cause, whichever occurs first. Per RECIST v1.1, Progressive Disease (PD): At least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study (this includes the baseline sum if that is the smallest on study). In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm.
