简要总结

Part 1of the study will evaluate the safety, pharmacokinetics, pharmacodynamics and immunogenicity of increasing doses of a vaccine-based immunotherapy regimen (VBIR-2) for patients with advanced or metastatic non-small cell lung cancer and metastatic triple-negative breast cancer.

Part 2 will evaluate the safety, pharmacokinetics and pharmacodynamics, immunogenicity and preliminary evidence of efficacy of the Expansion dose of VBIR-2 in participants with advanced or metastatic non-small cell lung cancer.

详细描述

The study is divided into two parts, Dose Escalation (Part 1) in participants with NSCLC and TNBC without acceptable alternative treatment options, followed by Dose Expansion (Part 2) in participants with NSCLC who have progressed on or after treatment with platinum-based chemotherapy and treatment with 1 immune checkpoint inhibitor, given concurrently or sequentially with chemotherapy.

Part 1 has been completed.

结局指标

主要结局

Number of Participants With Adverse Events (AEs) and Serious Adverse Events (SAEs)

时间窗: Baseline up to 6 months after End of Treatment (EOT; 22 months in maximum)

An AE was any untoward medical occurrence in a clinical investigation where participant administered a product; the event did not need to have a causal relationship with the treatment. Treatment-related AE was any untoward medical occurrence attributed to study drug in a participant who received study drug. An SAE was any untoward medical occurrence at any dose that resulted in death; was life threatening; required inpatient hospitalization or prolongation of existing hospitalization; resulted in persistent or significant disability/incapacity; resulted in congenital anomaly/birth defect or considered to be an important medical event. AEs included both SAEs and non-serious AEs.

Number of Participants With AEs Leading to Discontinuation or Dose Reduction

时间窗: Baseline up to 6 months after EOT (22 months in maximum)

An AE was any untoward medical occurrence in a clinical investigation where participant administered a product; the event did not need to have a causal relationship with the treatment.

Number of Participants With Laboratory Abnormalities in Hematology and Coagulation (Grade 3 or 4)

时间窗: Baseline up to 6 months after EOT (22 months in maximum)

Laboratory abnormalities (graded per NCI CTCAE v5.0: Grade 3: severe AE; Grade 4: life-threatening consequences, urgent intervention indicated) in at least 1 participant with data in the categories are presented here. Hematology parameters included hemoglobin, platelets, white blood cell (WBC) count, neutrophils, eosinophils, monocytes, basophils and lymphocytes. Coagulation should include prothrombin time (PT) or international normalized ratio (INR) and activated partial thromboplastin time (APTT).

Number of Participants With AEs as Graded by National Cancer Institute Common Terminology Criteria for Adverse Events Version 5.0 (NCI CTCAE v5.0) (Grade ≥3)

时间窗: Baseline up to 6 months after EOT (22 months in maximum)

An AE was any untoward medical occurrence in a clinical investigation participant administered a product; the event did not need to have a causal relationship with the treatment. Treatment-related AE was any untoward medical occurrence attributed to study drug in a participant who received study drug. Grades of AEs were defined by NCI CTCAE v5.0. Grade 1 = asymptomatic/mild symptoms, clinical or diagnostic observations only, intervention not indicated; Grade 2 = minimal, local or noninvasive intervention indicated, limiting age-appropriate instrumental activities of daily living (ADL); Grade 3 = severe or medically significant but not immediately life-threatening, hospitalization of prolongation of hospitalization indicated; disabling limiting self-care ADL; Grade 4 = events with life-threatening consequences, urgent intervention indicated; Grade 5 = death related to AE.

Number of Participants With Laboratory Abnormalities in Urinalysis (Grade 3 or 4)

时间窗: Baseline up to 6 months after EOT (22 months in maximum)

Urinalysis abnormalities (graded per NCI CTCAE v5.0: Grade 3: severe AE; Grade 4: life-threatening consequences, urgent intervention indicated) in at least 1 participant with data in the categories are presented here. Urine parameters included urine protein and urine blood.

Number of Participants With Dose-Limiting Toxicities (DLTs)

时间窗: The first 28 days following the first AdC68 vaccination (Cycle 1 Day 1)

AEs in the first 28 d (days) following the first AdC68 vaccination that were considered possibly related to study treatment and not to disease/progression were DLTs: Grade≥3 neutropenia lasting\>7 d, febrile neutropenia, Grade≥3 neutropenic infection, Grade≥3 thrombocytopenia with Grade≥2 clinically significant bleeding, Grade≥3 anemia lasting \>7 d, Grade≥3 lymphopenia lasting\>14 d; Grade≥3 lab abnormalities associated with symptoms or worsening of an existing condition or that suggested a new disease process or that required additional active management, Grade≥3 AEs considered non-hematologic, non-hepatic major organ toxicity, Grade 3 flu-like symptoms lasting\>3 d, fever of \>40.0 degree Celsius lasting\>3 d, concurrent aspartate aminotransferase or alanine aminotransferase \>3x upper limit of normal (ULN) and total bilirubin \>2x ULN (potential Hy's law case). Other clinically important or persistent toxicities at discretion of investigator and Pfizer.

Proportion of Participants Who Achieved Complete Response, Partial Response or Stable Disease for More Than 6 Months Using Response Evaluation Criteria in Solid Tumors (RECIST) v1.1 Criteria (Part 2)

时间窗: Performed every 8 weeks from baseline up to Week 32

Clinical Benefit Rate (CBR) is defined as the proportion of participants who achieved anti-tumor responses of Complete Response (CR), Partial Response (PR), or Stable Disease (SD) for \>6 months. CR was defined as complete disappearance of all target lesions and non-target disease, with the exception of nodal disease. All target nodes must decrease to normal size (short axis \<10 mm). All target lesions must be assessed. PR was defined as ≥30% decrease under baseline of the sum of diameters of all target lesions. The short axis was used in the sum for target nodes, while the longest diameter was used in the sum for all other target lesions. No unequivocal progression of non-target disease and no new lesions. All target lesions must be assessed. SD: Does not qualify for CR, PR or Progression. SD can follow PR only in the rare case that the sum increases by \<20% from the nadir, but enough that a previously documented 30% decrease no longer holds.

Number of Participants With Laboratory Abnormalities in Chemistry (Grade 3 or 4)

时间窗: Baseline up to 6 months after EOT (22 months in maximum)

Chemistry abnormalities (graded per NCI CTCAE v5.0: Grade 3: severe AE; Grade 4: life-threatening consequences, urgent intervention indicated) in at least 1 participant with data in the categories are presented here. Chemistry parameters included aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, sodium, potassium, magnesium, total chloride, total calcium, total bilirubin, blood urea nitrogen (or urea), creatinine, uric acid, glucose (nonfasted), albumin, phosphorous or phosphate, lactate dehydrogenase, lipase, amylase, bicarbonate or carbon dioxide, total protein, TSH (reflex free T4 and free T3).
