Clinical summary

Summary

The goal of this trial is to determine the efficacy and safety of Acasunlimab immunotherapy in combination with Pembrolizumab immunotherapy, compared to that of Docetaxel (a standard of care chemotherapy). During the trial, participants' quality of life will also be evaluated.

To be eligible, participants:

  1. must have lung cancer that has metastasised (spread).
  2. have tumours that are positive for PD-L1 proteiin ( a biomarker that may be predictive of response to therapy)
  3. will have been previously treated with a PD-1/PD-L1 inhibitor and a platinum-containing cancer therapy administered in combination or sequentially.

Eligible participants will be randomly assigned to one of two active treatment arms:

  • Experimental Arm: Acasunlimab and Pembrolizumab once every 6 weeks as an intravenous (IV) infusion, or
  • Active Comparator Arm: Docetaxel IV infusion once every 3 weeks.

The estimated trial duration for a participant will vary but may be up to 5 years, consisting of:

  • An optional 56-day pre-screening period
  • A 28-day screening period
  • Up to 2 years of treatment
  • A 90-day safety follow-up period
  • Post-treatment follow-up.

Conditions

This trial is treating people with metastatic non-small cell lung cancer (Stage IV) that is PD-L1+ and who have had prior treatment

Eligibility

Inclusion

  • Participant has histologically or cytologically confirmed metastatic NSCLC (stage IV).
  • Participant has progressed on or after receiving:

    • One prior line of therapy (PD-1/PD-L1 inhibitor and platinum-based chemotherapy concomitantly) in the metastatic disease setting; OR
    • No more than 2 prior lines of therapy (PD-1/PD-L1 inhibitor and platinum-based chemotherapy sequentially, irrespective of the order) in the metastatic disease setting.
  • Participant must have positive tumor PD-L1 expression (tumor cells ≥1%) determined prospectively on a tumor sample from the metastatic setting at a sponsor-designated central laboratory.
  • Participant has measurable disease according to RECIST v1.1 as assessed by the investigator at baseline.
  • Participant has an Eastern Cooperative Oncology Group (ECOG) performance status 0 or 1 within 7 days of Cycle 1 Day 1.
  • Participant has a life expectancy of ≥3 months.
  • Participant must have adequate organ and bone marrow function, per laboratory test results within 7 days of trial treatment.

Exclusion

  • Documentation of known targetable epidermal growth factor receptor (EGFR) sensitizing mutations, anaplastic lymphoma kinase (ALK), RET proto-oncogene (RET), ROS proto-oncogene 1; receptor tyrosine kinase (ROS1) rearrangement, Kirsten rat sarcoma virus (KRAS), BRAF mutations, and MET exon 14 skipping mutations/MET amplification. NOTE: MET amplification testing is optional based on local availability of the test.

    • Participants with known KRAS/BRAF mutations are eligible for the trial if they do not have access to approved targeted therapies.
  • Participants with newly identified or known unstable or symptomatic central nervous system (CNS) metastases or history of carcinomatous meningitis.
  • Prior treatment with docetaxel for NSCLC.
  • Prior treatment with a 4-1BB (CD137) targeted agent, any type of antitumor vaccine, autologous cell immunotherapy, or any unapproved immunotherapy.
  • Treatment with an anticancer agent within 28 days prior to the first dose of trial treatment.

Note: Other protocol-defined inclusion and exclusion criteria may apply.

Inclusion

  • Your cancer has spread to other parts of the body (metastatic) or has grown into nearby parts of the body (locally advanced).
  • You have had treatment but your cancer has gotten worse or has not responded to the treatment you have been given.
  • You have had a certain type of treatment or surgical procedure.

Exclusion

  • You have certain types of non-cancer medical conditions.
  • You have had certain treatments, surgical procedures or drugs.
