Study Details

Study Description

Brief Summary

To evaluate the safety and clinical activity of GEN1042 in combination with radiotherapy with or without pembrolizumab as a treatment option for patients with metastatic solid tumors

Condition or Disease Intervention/Treatment Phase
Phase 1/Phase 2

Detailed Description

The study will be conducted in two parts: part 1 (dose-finding) and part 2 (randomization).

Part 1 will evaluate the safety of immunoradiotherapy combinations and establish the dose(s) to be evaluated in Part 2.

Part 2 will evaluate the anti-tumor activity of immunoradiotherapy combinations at the established dose(s) from Part 1.

Participants in both parts are treated with one of the following combinations:
  • Radiotherapy + GEN1042

  • Radiotherapy + GEN1042 + pembrolizumab

While participants in part 1 are assigned sequentially (GEN1042 without pembrolizumab is investigated first), participants in part 2 are randomized 1:1 in the two treatment arms

    Outcome Measures

    Primary Outcome Measures

    1. Part 1: Dose limiting toxicities (DLTs) [During the first cycle (21 days) of each patient]

      To determine the maximum tolerated dose (MTD) and/or recommended phase 2 dose (RP2D)

    2. Part 2: Number of participants with abscopal response in non-irradiated target lesions [Throughout the trial until disease progression/death/lost to follow-up/start of new anticancer therapy or withdrawal of consent, whichever occurs first (an expected average of 5 months)]

      Assessed by investigator

    Secondary Outcome Measures

    1. Objective response rate (ORR) [Throughout the trial until disease progression/death/lost to follow-up/start of new anticancer therapy or withdrawal of consent, whichever occurs first (an expected average of 5 months)]

      Per RECIST v1.1 as assessed by the investigator

    2. Duration of response (DOR) [From onset date of response until disease progression/death/lost to follow-up/start of new anticancer therapy or withdrawal of consent, whichever occurs first (an expected average of 5 months)]

      Per RECIST v1.1 as assessed by the investigator

    3. Disease control rate (DCR) [Throughout the trial until disease progression/death/lost to follow-up/start of new anticancer therapy or withdrawal of consent, whichever occurs first (an expected average of 5 months)]

      Per RECIST v1.1 as assessed by investigator

    4. Progression-free survival (PFS) [From first dose (part 1) or randomization (part 2) to first documented progression or death due to any cause (an expected average of 5 months)]

      Per RECIST v1.1 as assessed by investigator

    5. Overall survival (OS) [From first dose of GEN1042 (part 1) or randomization (part 2) to date of death (assessed up to 3 years after the last participant's first dose in the trial)]

      Defined as the time from first administration of GEN1042 (part 1) or randomization (part 2) to date of death due to any cause

    6. Part 1: Number of participants with abscopal response in non-irradiated target lesions [Throughout the trial until disease progression/death/lost to follow-up/start of new anticancer therapy or withdrawal of consent, whichever occurs first (an expected average of 5 months)]

      Assessed by investigator

    7. Incidence and severity of adverse events (AEs) [Throughout the trial until end of safety follow-up period (30 days or 90 days after last dose)]

      Treatment emergent AEs (TEAEs) All participants should attend a safety follow-up visit 30 days after last dose. Only a proportion of the participants should also attend a safety follow-up visit 90 days after last dose.

    8. Number of participants with clinically significant shifts from baseline in safety laboratory parameters [Throughout the trial until end of safety follow-up period (30 days or 90 days after last dose)]

      Safety laboratory parameters assessed: hematology, biochemistry, and thyroid function All participants should attend a safety follow-up visit 30 days after last dose. Only a proportion of the participants should also attend a safety follow-up visit 90 days after last dose.

    9. Area under the concentration-time curve (AUC) of GEN1042 [Throughout the trial until the safety follow-up visit (30 days after last dose)]

    10. Maximum (peak) concentration (Cmax) of GEN1042 after dosing [Throughout the trial until the safety follow-up visit (30 days after last dose)]

    11. Elimination half-life (T1/2) of GEN1042 [Throughout the trial until the safety follow-up visit (30 days after last dose)]

    12. Number of participants with incidence of anti-drug antibodies (ADAs) [Throughout the trial until the safety follow-up visit (30 days after last dose)]
