Study Investigating ASP3082 in Patients With Metastatic/Locally Advanced Non-small-cell Lung Cancer (NSCLC) and Pancreatic Ductal Adenocarcinoma (PDAC), With Biomarker Analysis to Characterize Response/Resistance

Recruiting now · Phase 2

Conditions studied: Metastatic/Locally Advanced Non-Small-Cell Lung Cancer, Metastatic/Locally Pancreatic Ductal Adenocarcinoma

In brief

UNLOCK ASP3082 is an open label, single arm, multicenter, phase 2 platform study that aims to evaluate the mechanisms of action and resistance to ASP3082 in metastatic/locally advanced Non-Samll-Cell Lung Cancer (NSCLC) and Pancreatic Ductal Adenocarcinoma (PDAC) with the presence of KRAS G12D mutation. The two cohorts of patients are the following : i. cohort NSCLC : patients with NSCLC with KRAS G12D mutation. ii. cohort PDAC : patients with PDAC with KRAS G12D mutation. Patients enrolled in the both cohorts will receive treatment with ASP3082 at the dose of 600 mg QW thereafter in a 21-day cycle. ASP3082 will be administred in intravenous route until disease progression, unacceptable toxicity, or consent withdrawal. Tumor and blood samples will be collected at baseline, on-treatment and at the end of treatment visit only from patients who develop acquired resistance (acquired resistance is defined as a best response of CR, PR, or SD lasting more than 6 months, followed by PD).

You may qualify if…

• Age ≥18 years

• For patients with NSCLC :
• Patients with no known targetable genomic alterations, or an alteration for which no targeted therapy is approved (or accessible), must have been treated with at least 1 line of prior therapy, including a platinum-based regimen and a PD-(L) 1 blocker, combined or sequenced, and they must have experienced progression
• Patients who have known actionable genomic alterations (EGFR, BRAF, and MET mutations or ALK, ROS1, RET, NTRK fusions) must have exhausted the available targeted therapy and have experienced disease progression after a platinum-based regimen
• Patients with PDAC must have received only one prior line of chemotherapy for a minimum duration of 5 months and have experienced disease progression
• Patients must have an ECOG performance status ≤1 at the time of screening
• Patients must have a minimum life expectancy of 3 months
• Patients must have at least one radiologically measurable lesion according to response evaluation criteria in solid tumors (RECIST) v1.1 criteria
• Patients must have a tumor site easily accessible to biopsy, avoiding bone biopsy when possible. Patient must have accepted to perform pre-treatment, on-treatment, and end-of-treatment tumor and blood biopsies
• Patients must have adequate bone marrow reserve and organ function, based on local laboratory data within 21 days prior to cycle 1, day 1 defined as :
• Platelet count ≥100 000/mm3 or ≥100 × 109/L (platelet transfusions are not allowed up to 14 days prior to cycle 1 Day 1 to meet eligibility)
• Hemoglobin (Hgb) ≥9.0 g/dL (transfusion and/or growth factor support is allowed)
• Absolute neutrophil count (ANC) ≥1500/mm3 or ≥1.5 × 109/L (use of growth factors is not allowed in the 14 days prior cycle 1)
• Creatinine clearance (CrCl) : Creatinine clearance (CrCl) ≥60 mL/min as calculated using the Cockcroft-Gault equation or measured CrCl; confirmation of CrCl is only required when SCr is >1.5 × ULN
• Aspartate aminotransferase (AST)/alanine aminotransferase (ALT) and alkaline phosphatase (ALP) <3 x ULN (or <5 x ULN for patients with liver metastases)
• Total bilirubin (TBL) <1.5 x ULN (<3 x ULN in the presence of documented Gilbert's Syndrome [unconjugated hyperbilirubinemia]) or <2 X ULN for patients with liver metastases
• Serum albumin ≥ 3.0 g/dL
• Prothrombin time (PT) or Prothrombin time- international normalized ratio (PT-INR) and activated partial thromboplastin time (aPTT)/partial thromboplastin time (PTT) ≤1.5 × (ULN), except for patients on coumarin-derivative anticoagulants or other similar anticoagulant therapy, who must have PT-INR within therapeutic range as deemed appropriate by the Investigator
• Patients must have baseline oxygen saturation > 93% on room air
• Females of reproductive/childbearing potential must have a negative serum or urine pregnancy test at screening and must agree to use a highly effective form of contraception or avoid intercourse during and upon completion of the study and for at least 6 months for females after the last dose of study drug.
• Female patients must not donate, or retrieve for their own use, ova from the time of screening and throughout the study treatment period, and for at least 6 months after the final study drug administration
• Male patients must be surgically sterile or must withhold heterosexual intercourse or must be willing to use a highly effective birth control upon enrollment, during the treatment period, and for at least 3 months following the last dose of study drug
• Male patients must not freeze or donate sperm starting at screening and throughout the study period, and at least 3 months after the final study drug administration
• Patients must understand, sign and date the written informed consent form prior to any protocol-specific procedures performed. Patients should be able and willing to comply with study visits and procedures as per protocol

• Inadequate washout period prior to cycle 1 day 1, defined as:
• Whole brain radiation therapy or stereotactic brain radiation therapy <14 days
• Radiotherapy treatment to more than 30% of the bone marrow or with a wide field of radiation <28 days or palliative radiation therapy <7 days. Participant must have recovered from all radiation-related toxicities and not have active radiation pneumonitis.
