Study summary

This Phase 1 study is designed to assess the safety, tolerability, pharmacokinetics, and preliminary efficacy of AMV564 alone and in combination with Pembrolizumab in patients with advanced solid tumors.

Read the detailed description

AMV564-301 is a Phase 1, open-label, multicenter dose-escalation with expansion trial in patients with locally advanced or metastatic solid tumors. In the dose-escalation portion of the study, cohorts of patients will receive AMV564 alone or in combination with Pembrolizumab at increasing dose levels to determine the maximum tolerated dose (MTD) and/or the recommended dose for expansion. In the expansion portion of the study, one or more cohorts of patients will receive AMV564 at the MTD or recommended dose to further evaluate safety, tolerability, and clinical activity.

  • Measurable disease per Response Evaluation Criteria in Solid Tumors (RECIST) v1.1 or per other criteria best suited for the specific tumor type being evaluated
  • Willing to complete all scheduled visits and assessments at the institution administering therapy

Key Exclusion Criteria:

  • Treatment with any local or systemic antineoplastic therapy (including chemotherapy, hormonal therapy, or radiation) within 3 weeks prior to first dose of AMV564
  • Major trauma or major surgery within 4 weeks prior to first dose of AMV564
  • Prior treatment with chimeric antigen receptor (CAR) T-cell therapy or T-cell engager therapy
  • Chronic use of corticosteroids in excess of 10 mg daily of prednisone or equivalent within 4 weeks prior to first dose of AMV564
  • Adverse events from prior anti-cancer therapy that have not resolved to Grade ≤ 1 except for alopecia
  • Known, central nervous system (CNS) disease involvement, or prior history of National Cancer Institute Common Toxicity Criteria for Adverse Events (NCI CTCAE) Grade ≥ 3 drug-related CNS toxicity

What researchers measure

Primary outcomes

  1. Incidence of Treatment-Related Adverse Events

    As measured by the incidence, nature and severity of adverse events (AEs) and serious AEs

    Time frame: Through study completion, an average of 19 months

  2. Maximum tolerated dose of AMV564 in subjects with advanced solid tumors

    As determined based on the occurrence of dose-limiting toxicity

    Time frame: During Dose Escalation, an average of 6 months

  3. Preliminary evaluation of AMV564 efficacy in subjects enrolled in the expansion phase

    As measured by the objective response rate (ORR)

    Time frame: During Dose Expansion, an average of 1 year

Secondary outcomes

  1. Maximum observed drug concentration (Cmax) of AMV564

    Measured by plasma concentration

    Time frame: Through study completion, an average of 19 months

  2. Concentration at steady state (Css) of AMV564

    Measured by plasma concentration

    Time frame: Through study completion, an average of 19 months

  3. Time of the maximum drug concentration (Tmax) of AMV564

    Measured by plasma concentration

    Time frame: Through study completion, an average of 19 months

  4. Apparent terminal half-life (t½) of AMV564

    Measured by plasma concentration

    Time frame: Through study completion, an average of 19 months

  5. Area under the concentration-time curve (AUC) of AMV564

    Measured by plasma concentration

    Time frame: Through study completion, an average of 19 months
