Brief Summary:
IMCnyeso is a bispecific fusion protein designed for the treatment of cancers that express NY-ESO-1 and/or LAGE-1A. This was a first-in-human trial designed to evaluate the safety and efficacy of IMCnyeso in HLA-A*02:01-positive adult participants whose cancer is positive for NY-ESO-1 and/or LAGE-A1.

Condition or disease Intervention/treatment Phase
Select Advanced Solid Tumors Drug: IMCnyeso Phase 1 Phase 2

Detailed Description:
This was planned to be a multi-center, open label, dose finding Phase 1/2 study of single agent IMCnyeso administered in participants with NY-ESO-1 and/or LAGE-A1 positive tumors. The primary objective of the dose escalation phase (Phase 1) was to determine the maximum tolerated dose (MTD) and/or recommended Phase 2 dose (RP2D) of IMCnyeso in participants with advanced solid tumors. Preliminary efficacy was to be evaluated in Phase 2. The study was terminated early (prior to initiation of Phase 2) by the Sponsor as a strategic decision (not based on any safety signal).

Primary Purpose: Treatment
Official Title: A Phase I/II Study of IMCnyeso, HLA- A*0201-Restricted, NY-ESO-1- and LAGE-1A-specific Soluble T Cell Receptor and Anti-CD3 Bispecific Molecule, in HLA-A*0201 Positive Patients With Advanced NY-ESO-1 and/or LAGE - 1A Positive Cancer
Actual Study Start Date : June 15, 2018
Actual Primary Completion Date : May 10, 2021
Actual Study Completion Date : May 10, 2021

Arm Intervention/treatment
Experimental: Phase 1: Dose Escalation
Four fixed-dose, dose escalation cohorts (Cohorts 1 to 4) and 3 intrapatient dose escalation cohorts (Cohorts 5 to 7) to establish the MTD/RP2D of IMCnyeso.
Drug: IMCnyeso
Weekly IV infusions of IMCnyeso

Experimental: Phase 2: Dose Expansion
Three planned cohorts treated at the RP2D to make a preliminary assessment of the anti-tumor activity of IMCnyeso. Phase 2 was not initiated and data were not collected.
Drug: IMCnyeso
Weekly IV infusions of IMCnyeso




Primary Outcome Measures :
  1. Phase 1: Number of Participants With Dose-limiting Toxicities [ Time Frame: Up to 35 months ]
    Dose-limiting toxicities were defined as an adverse event or abnormal laboratory value assessed as having a suspected relationship to study drug that occurs within the evaluation period, from the first dose up until Day 28 after the first dose

  2. Phase 1: Number of Participants With Adverse Events [ Time Frame: Up to 35 months ]
    Treatment-emergent adverse events are defined as any adverse event (AE) that started after the first dose of study drug up to 30 days after last dose of study drug, including abnormal laboratory values, vital signs, or electrocardiogram results. AE severity is graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) version 4.03.

  3. Phase 1: Number of Participants With No Dose Interruptions or Reductions [ Time Frame: Up to 35 months ]
    Tolerability of study treatment was assessed by summarizing the number of participants with no treatment dose interruptions and dose reductions

  4. Phase 2: Best Overall Response (BOR) [ Time Frame: Up to 35 months ]
    Best overall response per RECIST v.1.1


Secondary Outcome Measures :
  1. Phase 2: Number of Participants With Adverse Events [ Time Frame: Up to 35 months ]
    Treatment-emergent adverse events are defined as any adverse event (AE) that started after the first dose of study drug up to 30 days after last dose of study drug, including abnormal laboratory values, vital signs, or electrocardiogram results.

  2. Phase 2: Number of Participants With No Dose Interruptions or Reductions [ Time Frame: Up to 35 months ]
    Tolerability of study treatment was assessed by summarizing the number of participants with no treatment dose interruptions and dose reductions

  3. Phase 1: Number of Participants With Best Overall Response (BOR) [ Time Frame: Up to 35 months ]
    Number of participants with best overall response, including complete response, partial response, stable disease, and progressive disease, based on local Investigator assessment as defined in RECIST v.1.1.

  4. Phase 1 and Phase 2: Progression-free Survival [ Time Frame: Up to 35 months ]
    Progression-free survival is defined as the time from first dose until the date of objective progression, or death from any cause, whichever occurs first.

  5. Phase 1 and Phase 2: Duration of Response [ Time Frame: Up to 35 months ]
    Duration of response is defined as the time from the date of first documented objective response (CR or PR) until the date of documented disease progression or death.

  6. Phase 1 and Phase 2: Overall Survival [ Time Frame: Up to 35 months ]
    Overall Survival is defined as the time (in months) from the date of randomization to the date of death due to any cause.

  7. Area Under the Plasma Concentration-time Curve From Time Zero to the Time of Last Measurable Concentration (AUC0-last) [ Time Frame: Predose and 1, 2, 4, 6, 8, and 12 hours post dose on Cycle 1 Day 1 and Cycle 1 Day 15 ]
  8. Maximum Observed Plasma Drug Concentration After Single Dose Administration (Cmax) [ Time Frame: Predose and 1, 2, 4, 6, 8, and 12 hours post dose on Cycle 1 Day 1 and Cycle 1 Day 15 ]
  9. Time to Reach Maximum Plasma Concentration (Tmax) [ Time Frame: Predose and 1, 2, 4, 6, 8, and 12 hours post dose on Cycle 1 Day 1 and Cycle 1 Day 15 ]
  10. Number of Participants With Anti-IMCnyeso Antibody Formation [ Time Frame: Up to 35 months ]
    Number of participants with positive treatment-boosted or treatment-induced anti-IMCnyeso antibody titers
