Study summary

The goal of this clinical trial is to: 1) evaluate the safety and recommended dose of the drug OT-101/Trabedersen when combined with Pembrolizumab and 2) determine the efficacy of the combination therapy in adults with certain types of Non-Small Cell Lung Cancer. The main question(s) it aims to answer are:

  • What medical problems to participants have when taking OT101 together with Pembrolizumab?
  • What is the correct dose of OT-101 to use when evaluating the safety and efficacy of the combination therapy?
  • Does the combination therapy delay progression or relapse of the participant\'s Non-Small Cell Lung Cancer?

Participants will:

  • Receive intravenous OT-101/Trabedersen for 4 days once every 2 weeks. Clinic visits are required to receive and disconnect the infusion.
  • Receive intravenous Pembrolizumab once every 6 weeks.

The main question(s) it aims to answer are:

  • What is the correct dose of OT-101 to use when evaluating the safety and efficacy of the combination therapy?
  • Does the combination therapy delay progression or relapse of the participants Non-Small Cell Lung Cancer?

Participants will:

  • Receive intravenous OT-101/Trabedersen for 4 days once every 2 weeks. Clinic visits are required to receive and disconnect the infusion.
  • Receive intravenous Pembrolizumab once every 6 weeks.

In Phase I, dose escalation/de-escalation of OT101/Trabedersen is performed using a BOIN design to determine dose limiting toxicity (DLT) and the recommended phase 2 dose (RP2D) when combined with Pembrolizumab.

In Phase II, subjects receive the RP2D of OT101/Trabedersen together with Pembrolizumab until disease relapse, progression [as determined by immune Response Evaluation Criteria in Solid Tumours (iRECIST) criteria], or death.

Study arms

  • Experimental
    Arm I: Dose Finding

    Participants receive either 140, 190, or 250 mg/m2 intravenous OT-101/Trabedersen for up to 12 weeks using a 4 days on 10 days off dosing schedule. The dose level is determined according to the Bayesian optimal interval (BOIN) design with cohort size 3. Participants receive concurrent administration of 400 mg intravenous Pembrolizumab every 6 weeks.
