About this study

Official title: A Phase I/II Open-label, Multi-center Study of the Safety and Efficacy of IMCgp100 Using the Intra-patient Escalation Dosing Regimen in Patients With Advanced Uveal Melanoma

IMCgp100-102 is a Phase I/II study of the weekly intra-patient escalation dose regimen with IMCgp100 as a single agent in participants with metastatic uveal melanoma (mUM). According to this regimen, all participants in the trial received 2 weekly doses of IMCgp100 at a dose level below the identified weekly recommended Phase II dose (RP2D-QW) and then a dose escalation commenced at the third weekly dose at C1D15. The Phase I testing of the intra-patient escalation dosing regimen is designed to achieve a higher exposure and maximal plasma concentration of IMCgp100 after doses at Cycle 1 Day 15 (C1D15) and thereafter.

Read the detailed description

This is a Phase I/II clinical study of IMCgp100 in participants with advanced uveal melanoma.

This is a Phase I/II study of IMCgp100 administered on a weekly basis with an intra-patient escalation dosing regimen. The intra-patient escalation occurred at the third weekly dose on Cycle 1 Day 15 (C1D15). According to this regimen, all participants in the trial received 2 weekly doses of IMCgp100 at a dose level below the identified weekly recommended Phase II dose (RP2D-QW), and then a dose escalation commenced at the third weekly dose at C1D15 with the goal to achieve a long-term dosing regimen at a dose higher than that identified for the weekly dosing regimen (RP2D-QW). The dose escalation identified the intra-patient escalation regimen (RP2D-IE).

The Phase I portion of the study was a standard 3+3 dose escalation design.The recommended Phase II dose of the intra-patient escalation dose regimen (RP2D-IE) was identified and expansion cohorts in metastatic uveal melanoma was accrued based on prior therapy.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Participants With a Dose Limiting Toxicity (DLT) in Phase 1

    Number of participants with a dose limiting toxicity, defined as an adverse event (AE) or abnormal laboratory value assessed as having a suspected relationship to study drug, and unrelated to disease, disease progression, inter-current illness, or concomitant medications that occurs within the first cycle of treatment and meets any of the pre-specified criteria.

    Measured: Up to 49 months

  2. Objective Response Rate in Phase 2

    Objective response rate (ORR) is defined as the percentage of participants with measurable disease with at least 1 visit response of complete response (CR) or partial response (PR) that is confirmed at least 4 weeks later, as defined in RECIST v.1.1 and assessed by an independent central review (ICR). The denominator in the calculation of the ORR is the number of participants in the full analysis set with measurable disease at baseline.

    Measured: Up to 38 months

Secondary outcomes (13)
  1. Objective Response Rate in Phase 1

    ORR is defined as the percentage of participants with measurable disease with at least 1 visit response of CR or PR that is confirmed at least 4 weeks later, as defined in RECIST v.1.1 and assessed by an investigator. The denominator in the calculation of the ORR is the number of participants in the full analysis set with measurable disease at baseline.

    Measured: Up to 49 months

  2. Progression-free Survival

    Progression-free survival is defined as the time in months from first dose of study drug until the date of disease progression or death (by any cause in the absence of disease progression) as assessed by RECIST v1.1 by the investigator for Phase 1 and ICR for Phase 2.

    Measured: Up to 49 months

  3. Disease Control Rate

    Disease control rate (DCR) is defined as the percentage of participants with a best overall response of CR or PR or stable disease (SD) recorded at least 24 weeks (± 1 week) after commencement of study drug and prior to any progressive disease (PD) event, as assessed by RECIST v1.1 by the investigator for Phase 1 and ICR for Phase 2.

    Measured: 24 weeks

  4. Duration of Response

    Duration of response (DOR) is defined as the time in months from the date of first documented objective response (CR or PR) until the date of documented disease progression or death by any cause in the absence of disease progression as assessed by RECIST v1.1 by the investigator for Phase 1 and ICR for Phase 2.

    Measured: Up to 49 months

  5. Time to Response

    Time to response (TTR) is defined as the time in months from the date of first dose of study drug until the date of first documented objective response as assessed by RECIST v1.1 by the investigator for Phase 1 and ICR for Phase 2.

    Measured: Up to 49 months

  6. Overall Survival

    Overall survival (OS) is defined as the time in months from the date of first dose of study drug until death due to any cause in general.

    Measured: Up to 49 months

  7. Minor Response Rate

    Rate of minor response (or better) is defined as the proportion of participants with a confirmed CR, PR, or minor response (MinR) as assessed by RECIST v1.1 by the investigator for Phase 1 or ICR for Phase 2, where MinR is a reduction from baseline in sum of diameters between 10%-29%. The sum of diameters is defined as per RECIST v1.1 as the sum of longest diameters or short axis of target lesions (mm).

    Measured: Up to 49 months

  8. Number of Participants With Treatment Dose Interruptions or Reductions

    Tolerability of study treatment was assessed by summarizing the number of participants with dose interruptions or reductions that occurred during the treatment period.

    Measured: Up to 49 months

  9. Area Under the Plasma Concentration-Time Curve (AUC) of Tebentafusp

    The AUC was determined in in dose escalation cohorts.

    Measured: Cycle 1 Day 1 and Cycle 1 Day 15: predose, end of infusion, and 4 and 8 hours postdose

  10. Maximum Plasma Concentration (Cmax) of Tebentafusp

    The Cmax is determined in dose escalation cohorts.

    Measured: Cycle 1 Day 1 and Cycle 1 Day 15: predose, end of infusion, and 4 and 8 hours postdose

  11. Time to Maximum Plasma Concentration (Tmax) of Tebentafusp

    The Tmax of tebentafusp is determined in dose escalation cohorts.

    Measured: Cycle 1 Day 1 and Cycle 1 Day 15: predose, end of infusion, and 4 and 8 hours postdose

  12. Apparent Terminal Plasma Half-life (t½) of Tebentafusp

    The t½ of tebentafusp is reported in dose escalation cohorts.

    Measured: Cycle 1 Day 1 and Cycle 1 Day 15: predose, end of infusion, and 4 and 8 hours postdose

  13. Percentage of Participants With Anti-IMCgp100 Antibody Formation

    Overall antidrug antibody (ADA) is presented as number of ADA-positive participants relative to total number of participants with evaluable ADA results in each cohort

    Measured: Up to 49 months
