E.2 Objective of the trial

E.2.1

Main objective of the trial

-To characterize the safety and tolerability of isatuximab in combination with REGN2810 in patients with metastatic, castration-resistant prostate cancer (mCRPC) who are naïve to anti-programmed cell death-1 (PD-1)/programmed cell death-ligand 1 (PDL-1)-containing therapy, or non-small cell lung cancer (NSCLC) who progressed on anti-PD-1/PDL-1-containing therapy, and to confirm the recommended Phase 2 dose (RP2D).
- To assess the response rate of isatuximab in combination with REGN2810 in patients with either mCRPC who are anti-PD-1/PDL-1 therapy naive, or NSCLC who progressed on anti-PD-1/PDL-1 therapy, or of isatuximab as single agent in patients with mCRPC

E.2.2

Secondary objectives of the trial

-To evaluate the safety of the combination of isatuximab with REGN2810 or isatuximab monotherapy.
-To evaluate the immunogenicity of isatuximab and REGN2810.
-To characterize the pharmacokinetic (PK) profile of isatuximab single agent or in combination with REGN2810, and to characterize the PK of REGN2810 in combination with isatuximab.
-To assess overall efficacy of isatuximab in combination with REGN2810 or as a single agent.

E.5 End points

E.5.1

Primary end point(s)

1) Dose Limiting Toxicities (DLTs): DLTs are following adverse events (AEs) in Cycle 1 unless due to disease progression or an obviously unrelated cause: Grade (G) 4 neutropenia >7 days; G 3 to 4 neutropenia with fever or documented infection; G 3 to 4 thrombocytopenia with bleeding requiring intervention; G 4 nonhematological AE; G ≥2 uveitis; G 3 non-hematological AE >3 days despite supportive care (with defined exceptions); Delay in initiation of the 2nd cycle >14 days for related laboratory abnormalities/AEs.
2) AEs: Number of patients with AEs based on standard and systematic assessment including changes in laboratory tests and vital signs according to the National Cancer Institute - Common Toxicity Criteria (NCI-CTC) version 4.03 Grade scaling
3) Response Rate: In non-small cell lung cancer (NSCLC): assessed and objective responses by RECIST 1.1; In metastatic castration-resistant prostate cancer (mCRPC): response will be defined per Prostate Cancer Working Group 3 (PCWG3) criteria

E.5.1.1

Timepoint(s) of evaluation of this end point

1) Up to 3 weeks after first study treatment administration
2) Up to 30 days after last study treatment administration (Up to approximately 25 months after first study treatment administration)
3) Up to 12 months from last patient in

E.5.2

Secondary end point(s)

1) Immunogenicity: isatuximab - Levels of anti-drug antibody against isatuximab
2) Pharmacokinetic (PK) parameters: area under the curve (AUC) : AUC is area under the drug concentration versus time curve
3) Tumor burden change: The best percent-change from baseline in a sum of the diameters for all target lesions
4) Duration of response: Defined as the time from the date of the first response that is subsequently confirmed to the date of first confirmed disease progression or death, whichever occurs first.
5) Progress-free survival: Defined as time from the first study treatment administration to the date of first documentation of progressive disease that is subsequently confirmed or the date of death from any cause
6) Assessment of PK parameter: Cmax - Cmax is maximum drug concentration observed
7) Immunogenicity: REGN2810 - Levels of anti-drug antibody against REGN2810
8) Disease control rate: Defined as the proportion of patients with confirmed complete response or partial response or stable disease, as assessed by Investigator relative to the total number of patients in the analysis population.

E.5.2.1

Timepoint(s) of evaluation of this end point

1) and 7) Up to 90 days following the last administration of study treatment or until the sample is negative (Up to approximately 27 months after first study treatment administration)
2) and 6) Up to 3 weeks after first study treatment administration
3), 4) , 5) and 8) Up to 12 months from last patient in
