A 2-part Phase 1/2 Open-label Trial Evaluating the Safety, Tolerability, Pharmacokinetics, Pharmacodynamics, and Efficacy of ODM-212 in Combination With Anti-cancer Therapy in Participants With Advanced Solid Tumours
An open-label, multi-site, multi-cohort phase 1/2 trial to be conducted in 2 parts (dose escalation and dose expansion/optimisation)
• Male or female participants ≥18 years old.
• Performance status 0-1 on the Eastern Cooperative Oncology Group (ECOG) Performance Scale.
• Life expectancy of \>12 weeks, in the opinion of the investigator.
• Ability to take oral medications and willing to record daily adherence to investigational product.
• Part 1: Participants with histologically or cytologically confirmed advanced or metastatic, unresectable solid tumors and who are able and willing to receive one of the anti-cancer therapies studied in this trial according to the investigator.
‣ Arm A: Participants with histologically or cytologically confirmed diagnosis of advanced (unresectable or metastatic) mesothelioma who are eligible to receive treatment with ipilimumab/nivolumab; participants must not have undergone surgical therapy for mesothelioma.
⁃ Arm B: Participants with histologically or cytologically confirmed metastatic adenocarcinoma of the pancreas who are eligible to receive treatment with nab-paclitaxel and gemcitabine.
⁃ Arm C: Participants with histologically or cytologically confirmed diagnosis of locally advanced or metastatic NSCLC and a KRAS G12C-mutation, confirmed using a validated test, who have received the available 1st line treatment and who are eligible for a treatment with sotorasib and have not received a KRAS G12C inhibitor as prior treatment.
∙ Part 2:
• Ipilimumab/nivolumab cohort: Participants with histologically or cytologically confirmed diagnosis of advanced (unresectable or metastatic) mesothelioma who are eligible to receive a treatment with ipilimumab/nivolumab. Prior treatment with ipilimumab, nivolumab and/or other PD-1/PD-L1/CTLA-4 inhibitors for advanced or metastatic disease is not allowed.
• Nab-paclitaxel/gemcitabine cohort: Participants with histologically or cytologically confirmed metastatic adenocarcinoma of the pancreas who are eligible to receive a treatment with nab-paclitaxel and gemcitabine. Previous treatments with nab-paclitaxel and/or gemcitabine for metastatic disease are not allowed.
• Sotorasib cohort, treatment naïve: Participants with histologically or cytologically confirmed diagnosis of locally advanced or metastatic NSCLC and a KRAS G12C-mutation, confirmed using a validated test, who are eligible for a treatment with sotorasib and have not received a KRAS G12C inhibitor as prior treatment.
• Sotorasib cohort, pretreated: Participants with histologically or cytologically confirmed diagnosis of locally advanced or metastatic NSCLC and a KRAS G12C mutation, confirmed using a validated test, who have documented progression on a prior KRAS G12C inhibitor (approved or investigational).
‣ Part 2 only: Participants must have measurable disease by response evaluation criteria in solid tumours (RECIST) v. 1.1 (modified RECIST for MPM).
⁃ A recent (taken up to 1 year ago), representative tumour tissue sample (from primary tumour or from metastasis) must be available. Tissue must be a core needle biopsy, excisional or incisional biopsy. Biopsies of bone lesions that do not have a soft tissue component or decalcified bone tumour samples are also not acceptable.
⁃ Amenable for paired fresh tumour biopsy at screening period and on-treatment.
