This study looks at how the drug PF-07934040 works and how safe it is, alone or together with other anti-cancer therapies, in people with advanced solid tumors carrying a KRAS gene mutation. It is enrolling patients with confirmed KRAS-mutated advanced tumors such as pancreatic cancer, colorectal cancer, or non-small cell lung cancer. It is being run as a Phase 1 study and is currently recruiting participants.
The summary above is a plain-language rendering of the official record. The original English title is shown for reference.
Criteria are reproduced from the ClinicalTrials.gov record in the original English. Only the trial team can determine eligibility.
Inclusion Criteria: * Histological or cytological diagnosis of advanced, unresectable, and/or metastatic or relapsed/refractory solid tumor. ECOG PS 0 or 1 * Presence of at least 1 measurable lesion based on RECIST version 1.1 that has not been previously irradiated. * Documentation of mutated KRAS gene 1. PDAC, CRC, Other tumor types: Confirmed KRAS mutation, any variant 2. NSCLC: Confirmed KRAS mutation, any variant except previously treated G12C. If driver mutation, must have failed precision medicine therapy \[eg, inhibitors of epidermal growth factor receptor (EGFR), anaplastic lymphoma kinase (ALK), c-ros oncogene 1 (ROS1), and others\]. * Part 1 and Part 2a: Participant must have progressed on standard treatment(s) for which no additional, effective therapy is available. 1. PDAC (2-3L): Participants must have received and radiologically progressed on prior lines of systemic therapy for metastatic pancreatic adenocarcinoma. If participants received prior neoadjuvant or adjuvant chemotherapy and progressed within 6 months of the last dose, then this should be considered as a prior line of systemic therapy. 2. NSCLC (2-3L): Participants must have received prior lines of anti-cancer treatment and progressed on at least a platinum-containing chemotherapy regimen or ICI. Participants may have had only one or two prior lines of therapy in the advanced/metastatic setting. For participants with EGFR, ALK, or other genomic tumor alterations, participants must have progressed on approved therapy for these alterations. 3. CRC (2-3L): Participants must have had one or two prior lines of therapy for mCRC. For either one or two prior treatments, these regimens must have included a fluoropyrimidine, oxaliplatin, and/or irinotecan for one prior treatment, exposure to VEGF/VEGF receptor (VEGFR) inhibitor is optional; 4. Other tumors: Participants, in the judgment of the investigator, must have progressed or become intolerant to all available standard therapies, or have refused such therapy. * Part 2b: 1. PDAC (1L) Cohort A2: Participants must not have received prior chemotherapy for metastatic disease. Participant could have received neoadjuvant therapy, adjuvant therapy, or adjuvant chemo-radiotherapy. If relapse occurred within 6 months of last dose of adjuvant treatment or neoadjuvant therapy, the participant would be considered 2L, and not 1L. 2. CRC (2-3L) Cohort B2: Participants must have had one or two prior systemic treatment regimens for mCRC. For either one or two prior treatments, these regimens must have included a fluoropyrimidine, irinotecan, oxaliplatin; for one prior treatment, exposure to a VEGF/VEGF receptor (VEGFR) inhibitor is optional. 3. CRC (1L) Cohort B3/B4: Participants must not have received prior therapy for metastatic disease and not be a candidate for other targeted therapy or immunotherapy. Participant could have received neoadjuvant therapy, adjuvant therapy, or adjuvant chemo-radiotherapy. If relapse occurred within 6 months of last dose of adjuvant or neoadjuvant therapy, then the participant would be considered 2L, and not 1L. 4. NSCLC (1L) Cohort C2: Participants must have a TPS ≥50% and must not have received prior systemic treatment setting. 5. NSCLC (1L) Cohort C3: Participants with any TPS and must not have received prior systemic treatment setting. Exclusion Criteria: * Active or history of pneumonitis/ILD or pulmonary fibrosis requiring treatment with systemic steroid therapy. * Diagnosis of immunodeficiency or an active autoimmune disease that require systemic treatment with chronic systemic steroid therapy (in dosing exceeding 10 mg daily of prednisone equivalent) or any other form of immunosuppressive therapy in the past 2 years. * Sensory peripheral neuropathy ≥Grade 2 * Active or history of clinically significant gastrointestinal (GI) disease (including but not limited to inflammatory GI disease \[eg, ulcerative colitis, Crohn's disease, inflammatory bowel disease\], immune-mediated colitis, peptic ulcer disease, GI bleeding, chronic diarrhea) and other conditions that are unresolved and/or may increase the risk associated with study participation or study treatment administration. * Active bleeding disorder, including GI bleeding, as evidenced by hematemesis, significant hemoptysis or melena in the past 6 months. * Major surgery or completion of radiation therapy ≤4 weeks prior to enrollment/randomization or radiation therapy that included \>30% of the bone marrow. * Known sensitivity or contraindication to any component of study intervention (PF 07934040, gemcitabine, nab-paclitaxel, cetuximab, bevacizumab, FOLFOX, 5-FU, pembrolizumab, cisplatin, carboplatin, pemetrexed, SHP2 inhibitor(s), cyclin-dependent kinase (CDK) inhibitor(s), antibody drug conjugates (ADCs) or EGFR inhibitor(s)). * Hematologic abnormalities. * Renal impairment. * Hepatic abnormalities.
