Lung Cancer Clinical Trial
Study of GT103 in Combination With Pembrolizumab in Refractory, Metastatic Non-Small Cell Lung Cancer
This open-label, non-randomized Phase II trial is designed to assess the safety and tolerability of GT103 in combination with pembrolizumab in adult subjects with relapsed or refractory, metastatic NSCLC. The study will consist of a safety lead-in of 10-20 patients. A total of 50 patients will be treated with the combination at the safest dose of GT103 as determined in the safety lead-in. If 10 additional patients are enrolled to the dose level -1 then the maximum of 60 subjects may be accrued to this trial.
Subject must meet all of the following applicable inclusion criteria to participate in this study:
Written informed consent and HIPAA authorization for release of personal health information prior to registration. NOTE: HIPAA authorization may be included in the informed consent or obtained separately.
Age ≥ 18 years at the time of consent.
ECOG Performance Status 0 or 1 within 14 days prior to registration.
Histologically and/or cytologically confirmed Stage III-IV recurrent or metastatic NSCLC (American Joint Committee on Cancer (AJCC) Staging Manual 8th ed).
Relapsed or refractory to immunotherapy. NOTE: anti-PD-1/PD-L1; prior anti-CTLA4 therapy is permitted; a minimum of 2 doses of prior immunotherapy is required. Prior treatment with chemotherapy is permitted. Neoadjuvant or adjuvant therapy is considered a line of treatment if given within 6 months of recurrent/metastatic disease. No more than 2 prior lines of therapy is permitted (this does not include oral targeted therapy).
Patients with EGFR, ALK, RET, BRAF, ROS1, or MET exon 14 alterations must have received at least one prior TKI and prior chemotherapy (at least one platinum doublet regimen; i.e. carboplatin/cisplatin plus pemetrexed/ paclitaxel/docetaxel/gemcitabine). No more than 2 prior lines of therapy is permitted (this does not include oral targeted therapy). BRAF and MET exon 14 alterations must have had prior oral targeted therapy.
Disease must be measurable by RECIST 1.1 criteria. Tumor lesions in a previously irradiated area are considered measurable IF progression has been demonstrated in such lesions after radiation.
Demonstrate adequate organ function as defined in the table below. All screening labs to be obtained within 14 days prior to C1D1.
Absolute Neutrophil Count (ANC): ≥1500/µL
Platelet Count: ≥100 000/µL
Hemoglobin (Hgb): ≥ 9 g/dL; Criteria must be met without erythropoietin dependency and without packed red blood cell (pRBC) transfusion within last 2 weeks.
---Serum creatinine OR Calculated creatinine clearance: ≤ 1.5 × ULN OR ≥ 30 mL/min for participant with creatinine levels >1.5 × institutional ULN
Total Serum Bilirubin: ≤1.5 ×ULN (Patients with known Gilbert Syndrome, a total bilirubin ≤ 3.0 x ULN, with direct bilirubin ≤1.5 × ULN)
Aspartate aminotransferase (AST) AND Alanine aminotransferase (ALT): ≤ 2.5 × ULN (≤5 × ULN for participants with liver metastases)
Coagulation ---International Normalized Ratio (INR) or Prothrombin Time (PT) Activated Partial Thromboplastin Time (aPTT): ≤ 1.5 × ULN unless participant is receiving anticoagulant therapy as long as PT or aPTT is within therapeutic range of intended use of anticoagulants
Females of childbearing potential must have a negative urine or serum pregnancy test at screening and within 72 hours of C1D1. See protocol for definition of childbearing potential.
Females of childbearing potential and males must be willing to abstain from heterosexual intercourse or to use an effective method(s) of contraception as outlined in protocol.
As determined by the enrolling physician or protocol designee, ability of the subject to understand and comply with study procedures for the entire length of the study.
Subjects meeting any of the criteria below may not participate in the study:
Patients currently receiving anticancer therapies or who have received anticancer therapies within 14 days prior to day 1 of study drug (including investigational agents, chemotherapy, and antibody-based therapy).
Radiation therapy within 14 days prior to day 1 of study drug. A 1-week washout is permitted for palliative radiation (≤ 2 weeks of radiotherapy) to non-CNS disease.
Intolerance to pembrolizumab or other PD-1/PD-L1 axis drug(s), or any other antibody or drug specifically targeting T-cell co-stimulation or immune checkpoint pathways, including prior therapy with anti-tumor vaccines or other immune-stimulatory anti-tumor agents.
Known auto-immune conditions requiring systemic immune suppression therapy other than prednisone ≤10 mg daily (or equivalent).
History of (non-infectious) interstitial pneumonitis/interstitial lung disease that required steroids or has current pneumonitis/interstitial lung disease.
Receipt of allogeneic transplant (stem cell transplantation or solid organ).
Current use of medications specified by the protocol as prohibited for administration in combination with the study drugs. This includes patients with a condition requiring systemic treatment with either corticosteroids (>10 mg daily prednisone equivalents) or other immunosuppressive medications within 14 days prior to day 1 of study drug. Inhaled or topical steroids and adrenal replacement doses >10 mg daily prednisone equivalents are permitted in the absence of active autoimmune disease.
Known history of HIV seropositivity or known acquired immunodeficiency syndrome (AIDS), hepatitis C virus (allowed if received curative therapy), acute or chronic active hepatitis B infection, or other serious chronic infection requiring ongoing treatment. NOTE: no testing for Hepatitis B, Hepatitis C or HIV is required unless mandated by local health authority.
Current active infectious disease requiring systemic antibiotics, antifungal, or antiviral treatment on Day 1 of study drug. Patients receiving prophylactic antibiotics (e.g., for prevention of urinary tract infection or chronic obstructive pulmonary disease) are eligible.
Pregnant or breastfeeding (NOTE: breast milk cannot be stored for future use while the mother is being treated on study).
Patients with a prior or concurrent malignancy whose natural history or treatment has the potential to interfere with the safety or efficacy assessment of the investigational regimen, per treating physician discretion, are not eligible for this trial.
Known active CNS metastases which are symptomatic. Eligible if metastases have been locally treated 14 days prior to Cycle 1 Day 1, are clinically controlled, or asymptomatic on Cycle 1 Day. Steroid dose must be equivalent of ≤10 mg prednisone daily or equivalent dose steroid. Untreated, asymptomatic brain metastases allowed if subject does not require corticosteroids or anticonvulsant therapy.
History of myocardial infarction, NYHA class III or IV congestive heart failure, or unstable angina, cardiac or other vascular stenting, angioplasty, or surgery within 6 months prior to study enrollment.
Has received a live vaccine or live-attenuated vaccine within 30 days prior to the first dose of study drug. Administration of killed vaccines is allowed.
