Brief Summary:
A Phase IIa Open-Label Trial to Investigate the Safety, Tolerability, Pharmacokinetics, Biological, and Clinical Activity of AGEN1884 in Combination with Pembrolizumab in Subjects with Chemotherapy Naïve, PD-L1 high, metastatic Non-Small Cell Lung Cancer (NSCLC)

Condition or disease Intervention/treatment Phase
NSCLC Stage IV Biological: AGEN1884 in combination with pembrolizumab Phase 2

Detailed Description:

This is a Phase IIa, open-label study, of AGEN1884 in combination with pembrolizumab in subjects with stage IV NSCLC whose tumors have high PD-L1 expression and no EGFR or ALK genomic tumor aberrations.

The study consists in two phases:

  • Safety Run-in Phase
  • Efficacy Phase

Subjects will be enrolled in a "3+3" Safety Run-in followed by enrollment completing the efficacy cohort. Two different dose levels of AGEN1884 may be tested in combination with the approved pembrolizumab treatment for this indication (until disease progression, unacceptable toxicity, or up to a maximum of 24 months). Each subject will stay on the dose level assigned at trial entry.


Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 26 participants
Intervention Model: Single Group Assignment

Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  1. Voluntarily agree to participate.
  2. Be ≥18 years of age.

  4. Have measurable disease based on RECIST 1.1 as determined by the site.
  5. Have a life expectancy of at least 3 months and a performance status of 0 or 1 on the Eastern Cooperative Oncology Group (ECOG) Performance Status
  6. Have adequate organ function as indicated by the following laboratory values:

    1. Adequate hematological function defined by absolute neutrophil count (ANC) > 1.5 x 109/L, platelet count > 100 x 109/L, and hemoglobin > 9 g/dL (without transfusions within 2 weeks of first dose).
    2. Adequate hepatic function based by a total bilirubin level < the institutional upper limit of normal (IULN), aspartate aminotransferase (AST) level < 1.5 x IULN, alanine aminotransferase (ALT) level < 1.5 x IULN, and alkaline phosphatase ≤ 2.5 ULN.
    3. Adequate renal function defined as Creatinine ≤ 1.5 x IULN OR calculated creatinine clearance > 60 mL/min for subjects with creatinine levels > 1.5 x IULN (If no local guideline is available, creatinine clearance should be calculated using the Cockcroft-Gault Method).
    4. Adequate coagulation defined by international normalized ratio (INR) or prothrombin time ≤ 1.5 x IULN (unless the subject is receiving anticoagulant therapy); and activated partial thromboplastin time (aPTT) ≤ 1.5 x IULN (unless the subject is receiving anticoagulant therapy)
    5. Adequate endocrine function defined by thyroid stimulating hormone (TSH) within normal limits. Note: if TSH is not within normal limits at baseline, the subject may still be eligible if T3 and free T4 are within normal limits.
  7.

  9. The subject's tumor does not harbor an EGFR sensitizing (activating) mutation or ALK translocation.
  10. The subject's tumor must have high PD-L1 expression (TPS ≥50%) as determined by an FDA-approved test.

  10. Has had an allogeneic tissue/solid organ transplant.
  11. Has interstitial lung disease (ILD) OR has had a history of pneumonitis that has required oral or IV steroids.
