This study explores the study medicine PF-07985045, given alone or with other anti-cancer therapies, in people with advanced solid tumors that have a change (mutation) in the KRAS gene. Patients with KRAS-mutated tumors such as pancreatic, non-small cell lung, or colorectal cancer that have progressed despite standard therapy may take part. It is a Phase 1 study that is currently active but not recruiting.
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. * Note for PDAC: Only participants with the histologic type of adenocarcinoma of the pancreas are allowed to enroll. For PDAC, if loco-regional disease is present, must also have metastatic disease. * Note for NSCLC: If a driver mutation is present, the participant was resistant or intolerant of precision medicine therapy (eg, inhibitors of EGFR, ALK, ROS1, or others). * 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 a. KRAS mutations of any variant except previously treated with any KRAS inhibitor * Part 1: 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 and/or checkpoint inhibitor therapy; 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 only one or two prior systemic treatment regimens for mCRC. For either one or two prior treatments, these regimens must have included a fluoropyrimidine, oxaliplatin, 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 2: 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, as long as relapse did not occur within 6 months of completing these forms of adjuvant treatment. If so, the relapse within 6 months would be considered a line of 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: Participants must not have had prior chemotherapy for advanced or metastatic disease. Participant could have received adjuvant chemotherapy or adjuvant chemo-radiotherapy, as long as relapse did not occur within 6 months of complete of adjuvant therapy. If so, the relapse within 6 months would be considered a line of therapy; 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 pneumonitis/ILD, pulmonary fibrosis requiring treatment with systemic steroid therapy. Additionally, participants in IO combinations (Cohorts C2 and C3) with history and/or active pneumonitis/ILD or pulmonary fibrosis requiring steroids are excluded from enrollment. * 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. * Has symptomatic ascites or pleural effusion. A participant who is clinically stable following treatment for these conditions (including drainage catheter placement, therapeutic thoracentesis or abdominal paracentesis) is eligible. * Current use or have received PPIs in the last seven days prior to starting study treatment. * Known sensitivity or contraindication to any component of study intervention (PF-07985045, gemcitabine, nab-paclitaxel, cetuximab, bevacizumab, FOLFOX, 5-FU, pembrolizumab, sasanlimab, cisplatin, carboplatin, pemetrexed, SHP2 inhibitor(s). * Hematologic abnormalities. * Renal impairment. * Hepatic abnormalities.
