Brief Summary

This study is designed to characterize the safety, tolerability, and anti-tumor activity of MDX2001 in patients with advanced solid tumors.

Detailed Description

This study consists of Phase 1a dose escalation, Phase 1b dose expansion in a single indication, and Phase 2a expansion in a single indication.

Primary Objectives

* All Phases: Evaluate the safety and tolerability of MDX2001 in patients with advanced solid tumor malignancies

* Phase 1 only: Identify a recommended Phase 2 dose (RP2D) for further development of MDX2001

* For Phase 1b and Phase 2: Assess the anti-tumor efficacy of MDX2001 in patients with selected advanced solid tumor malignancies

Secondary Objectives:

* Further characterize the anti-tumor activity of MDX2001 based on additional assessments of clinical benefit

* Characterize the pharmacokinetics of MDX2001

* Characterize the immunogenicity of MDX2001

* Characterize relationship of baseline target protein expression in tumor tissue and clinical benefit

The expected duration of study intervention for patients may vary, based on progression date. The median expected duration of study per patient is estimated to be 10 months (up to 1 month for screening, a median of 6 months for treatment, and a median of 3 months for long term follow-up).

Primary Outcome Measures
NameTimeMethod
All Phases: Adverse events (AEs)Baseline until end of study, up to approximately 9 months

Incidence and severity of AEs and serious AEs (SAEs) graded according to the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) v5.0 including changes in clinical laboratory parameters

Phase 1b and Phase 2a: Objective response rate of MDX2001From date of enrollment until the end of treatment, up to approximately 6 months

Objective response rate is defined as the proportion of patients who achieve a complete response (CR) or partial response (PR) per Response Evaluation Criteria in Solid Tumors (RECIST) v1.1.

Phase 1: Recommended Phase 2 dose (RP2D)Baseline until end of study, up to approximately 9 months

Recommended Phase 2 dose is determined following the evaluation of MDX2001 safety including the incidences of dose limiting toxicities (DLTs), MDX2001 anti-tumor activity, and MDX2001 pharmacokinetics

Secondary Outcome Measures
NameTimeMethod
All Phases: Time to response (TTR)From date of enrollment until the first documentation of response (CR or PR), approximately 4 months

Time to response is defined as the time from first dose to first documentation of response (CR or PR)

All Phases: Disease control rate (DCR)From date of enrollment until the end of treatment, up to approximately 6 months

Disease control rate is defined as the proportion of evaluable patients with a best overall response (BOR) of stable disease, CR or PR

All Phases: Pharmacokinetic Parameter Cmax of MDX2001From date of enrollment until completion of the 6th cycle of treatment, up to approximately 6 months

Maximum observed plasma concentration

All Phases: Pharmacokinetic parameter area under the curve (AUC(0-T)) of MDX2001From date of enrollment until the completion of the 3rd cycle of treatment, up to approximately 3 months

Area under the plasma concentration versus time curve

All Phases: Evaluation of MDX2001 immunogenicityBaseline until end of study, up to approximately 9 months

The presence and persistence of anti-MDX2001 antibodies

All Phases: Correlation between tumor antigen expression and anti-tumor activity of MDX2001Baseline until the end of treatment, up to approximately 6 months

Relationship between H score cell surface target protein expression in tumor tissue at baseline and objective responses with MDX2001

Phase 1a: Objective response rate of MDX2001From date of enrollment until the end of treatment, up to approximately 6 months

Objective response rate is defined as the proportion of patients who achieve a complete response (CR) or partial response (PR) per RECIST v1.1.

All Phases: Duration of response (DOR)From date of enrollment until the end of treatment, up to approximately 6 months

Duration of response is defined as the time from first documentation of response (complete response \[CR\] or partial response \[PR\]) to documentation of objective disease progression or death due to any cause, whichever occurs first

All Phases: Progression free survival (PFS)From date of enrollment until the end of treatment, up to approximately 6 months

Progression-free survival is defined as the time from the first dose to the date of disease progression or death (any cause), whichever occurs first
