Who may be able to join

  • In order to be eligible for participation in this trial, the patient must:
  • Have histologically or cytologically confirmed diagnosis of NSCLC (squamous or non-squamous) with positive expression of MAGE-A3 (primary or metastatic lesion).
  • Phase 1: Have radiographic progression after treatment with at least 1 cycle of platinum-doublet chemotherapy and/or at least one treatment of PD-1 or PD-L1 antibody targeted therapy. Adjuvant therapy will count as a regimen if administered within 1 year before relapse.
  • Phase 2: Have radiographic progression during or after treatment with anti-PD-1/PD-L1 antibody. Adjuvant therapy will count as regimen if administered within 1 year before relapse.
  • Phase 1: Patients with tumors of non-squamous NSCLC histology that have a known epidermal growth factor receptor (EGFR) mutation and/or anaplastic lymphoma kinase (ALK) translocation can participate in the Phase 1 portion of the study if they have failed the appropriate tyrosine kinase inhibitor (TKI) (intolerance or documented progression of their NSCLC) and have documented progression of their NSCLC. There is no preferred order of treatment with TKI or platinum doublet therapy. If a patient is found to have one molecular alteration (either sensitizing EGFR mutation or ALK translocation), then testing for the other alteration is not required.
  • Phase 2: Patients with the above ALK and EGFR targetable mutations will not be eligible for treatment.

About this study

Official title: A Phase 1/2 Trial of MG1 Maraba Expressing MAGE-A3 (MG1-MAGEA3), With Adenovirus Vaccine Expressing MAGE-A3 (Ad-MAGEA3), in Combination With Pembrolizumab in Patients With Previously Treated Metastatic Non-Small Cell Lung Cancer (NSCLC)

This is a Phase 1/2, multi-center, open-label, dose-escalation trial of Ad-MAGEA3 and MG1-MAGEA3 in combination with pembrolizumab in patients with Non-Small Cell Lung Cancer who have completed a first standard therapy with at least 1 cycle of platinum based chemotherapy and/or at least one treatment of PD-1 or PD-L1 antibody targeted therapy.

Read the detailed description

This is a Phase 1/2, open-label, dose-escalation trial of Ad MAGEA3 and MG1-MAGEA3 in combination with pembrolizumab in patients with NSCLC (histological subtype of squamous and non-squamous NSCLC). In Phase 1, patients who have progressed after treatment with a platinum-based regimen and/or PD-1/PD-L1 targeted antibody therapy will be enrolled. In Phase 2, only patients who have progressed after treatment regimen containing PD-1/PD-L1 targeted antibody therapy will be enrolled. In the Phase 1 portion of the study, MG1-MAGEA3 treatment will be escalated in a sequential dose-escalating design. In the Phase 2 portion of the study, MG1-MAGEA3 treatment will be at the maximum tolerated dose (MTD) or the maximum feasible dose (MFD). The Ad-MAGEA3 and pembrolizumab dose is fixed in both the Phase 1 and Phase 2 portions of the trial.

Phase 1 Enrollment

Cohorts 1 through 5:

Three patients will be treated at each dose level unless a dose-limiting toxicity (DLT), as defined below, is observed. Patients will be observed for a DLT through Day 29. After enrollment of the first patient in each cohort, 2 additional patients will be enrolled after the initial patient reaches Day 29 without experiencing a DLT. Treatment with MG1-MAGEA3 will proceed to the next dose level if 0 of 3 patients experiences a DLT. If one of the first 3 patients experiences a DLT, additional patients will be enrolled until a second patient experiences a DLT (which defines the toxic dose) or until 6 total patients have been treated, whichever comes first. If a second DLT is not experienced within that cohort, dose escalation may continue.

If 2 DLTs are observed within a cohort, enrollment into the cohort will cease and the dose level immediately preceding that dose will be determined as the MTD.

Ad-MAGEA3 will be administered by intramuscular (IM) injection at a dose level of 2 x 1011 virus particles (VP) on Day 1. MG1-MAGEA3 will be administered by intravenous (IV) infusion at escalating dose levels on Day 15 and Day 18. In Cohorts 1 through 5, patients will receive pembrolizumab at a dose of 200 mg IV on Day 22, and every 3 weeks thereafter until confirmed radiographic progression or unmanageable toxicity.

Cohort 6:

Upon determination of the MTD/MFD (safety assessment) in Cohorts 4-5, the treatment regimen will next be optimized such that pembrolizumab will begin on Day 1 (concurrent treatment). The Day 15 and Day 18 doses of MG1-MAGEA3 will be the doses defined as the MTD/MFD in either Cohort 4 or5. Specifically, the regimen evaluated in Cohort 6 is as follows:

  • Day 1: Patients will receive 2 x 1011 VP IM of Ad-MAGEA3 and 200 mg IV of pembrolizumab (the Pembrolizumab will be continued every 3 weeks [Q3W]).
  • Day 15: Patients will receive IV MG1-MAGEA3 at the MTD/MFD established for the first infusion from Cohort 4 or Cohort 5.
  • Day 18: Patients will receive IV MG1-MAGEA3 at the MTD/MFD established for the second infusion from Cohort 4 or Cohort 5.
  • Three patients will be treated according to the dose schedule above unless a DLT is observed between Day 1 and Day 29, at which time three additional patients will be enrolled onto this cohort. If 2 DLTs occur within these six patients treated in Cohort 6, this cohort will be stopped and a new Cohort will be initated again with patients treated concurrently with pembrolizumab but with a 0.5 log lower dose of MG1-MAGEA3 than used in Cohort 6 for the Day 15 and Day 18 doses.

Phase 2 Enrollment Phase 2 enrollment will commence upon completion of dose escalation and determination of the MTD/MFD. In Stage 1 of the 2-Stage design, 18 evaluable patients will be treated at the MTD/MFD (this will include patients treated at the MTD/MFD in Phase 1 who meet Phase 2 inclusion criteria). If 1 or more patients respond, the study may continue to Stage 2, and an additional 14 evaluable patients will be enrolled for a total of 32 evaluable patients.

A patient will be defined as being evaluable for the primary endpoint (EPPE) and included in the Simon 2-stage study design if they are seronegative to adenovirus Type 5, the virus used in the prime.

Preliminary data from two other Turnstone Ad/MG1-MAGEA3 trials indicates that patients without pre-existing anti-adenovirus antibodies (seronegative) prior to treatment have a greater likelihood of generating MAGEA3 specific T-cell responses than those that are seropositive at baseline. Therefore, this study is designed to primarily determine the response rate and clinical outcome for this homogenous population of Ad5 seronegative patients whom are most likely to benefit from Ad/MG1-MAGEA3 treatment. However, there is a small subset of seropositive patients who developed significant anti-MAGEA3 T-cell responses after Ad/MG1-MAGEA3 treatment. In addition, the presence of Ad5 seropositivity would not be expected to have any significant impact on the potential benefit of MG1-MAGEA3 tumor oncolysis. Therefore, exploratory data on clinical and immune response in the Ad5 seropositive population will be conducted and the study will enroll both Ad5 seronegative and positive patients.

It is anticipated that approximately half of the patients enrolled will be seronegative to Ad5, therefore Stage 1 of the Simon 2-stage design above will enroll approximately 18 patients and Stage 2 will enroll approximately 14 patients. Total study enrollment is projected to be between 2 and 100 patients.

Safety Committee:

Prior to each dose level increase or the initiation of Phase 2, a safety committee composed of independent voting members and treating physician(s) will review toxicity and other relevant data to determine suitability of dose escalation or expansion with regards to patient safety. Interim assessments of toxicity will be conducted throughout the trial to monitor for safety trends and identify any new or increased toxicity not previously associated with the IPs.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 29 inclusion and 40 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 6 Oct 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 6 sites in Canada. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Phase 1 - Toxicity as measured by adverse events (time frame: 7 months). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02879760, which also lists 2 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 Oct 2020.
