Brief summary
The purpose of this first-in-human study is to evaluate the safety, tolerability, pharmacokinetics (PK), pharmacodynamics (PD), and preliminary efficacy of AMG 410 when administered alone or in combination with other agents in participants with advanced or metastatic solid tumors harboring KRAS alterations. This is a dose-escalation study in which participants will be assigned to multiple dose levels (DLs) of AMG 410, either as monotherapy or in combination with other agents, followed by expansion cohorts. The goal is to determine the Maximum Tolerated Dose (MTD)-the highest dose with acceptable safety and manageable side effects-or the Recommended Phase 2 Dose (RP2D) of AMG 410 in adult participants with KRAS-altered advanced or metastatic solid tumors.
Detailed description
This is a multicenter, multinational, open-label Phase 1/1b study designed to evaluate the safety, tolerability, PK, PD, and preliminary antitumor activity of AMG 410 in adult participants with advanced or metastatic solid tumors characterized by KRAS alterations. The study will begin with a dose-escalation phase, during which AMG 410 will be administered orally, either as monotherapy or in combination with other agents. Dose escalation will follow a model-based approach to identify the MTD or RP2D. Following dose escalation, additional expansion cohorts may be enrolled at selected dose levels to further characterize the safety profile, PK/PD relationships, and preliminary efficacy in specific tumor types or molecular subgroups. Participants will continue treatment until disease progression, unacceptable toxicity, withdrawal of consent, or other protocol-defined discontinuation criteria. The maximum duration of AMG 410 administration in this study is 3 years.

Eligibility
Inclusion criteria
1. Age ≥ 18 years (or \> legal age within the country if it is older than 18 years). 2. Pathologically documented, locally-advanced or metastatic malignancy with any missense mutation in the KRAS gene or evidence of KRAS amplification using an analytically validated KRASWT amplification assay. 3. Participants must have no standard of care treatment options or have actively refused such therapy. 4. Able to swallow and retain per oral administered study treatment. 5. Eastern Cooperative Oncology Group (ECOG) Performance Status of 0 or 1. 6. Disease measurable as defined by Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST v1.1), as determined by the site investigator. 7. Adequate organ function. 8. Archival (formalin-fixed, paraffin-embedded \[FFPE\]) tumor tissue or block collected within 5 years before screening must be available. Participants without archived tumor tissue may undergo tumor biopsy before AMG 410 dosing (Day1).
Exclusion criteria
1. Untreated symptomatic central nervous system or leptomeningeal metastases. 2. Uncontrolled pleural effusion and/or ascites. 3. History of other malignancy within the past 5 years. 4. Active systemic infection or symptoms that indicate an acute and/or uncontrolled infection requiring IV antibiotics within 7days prior to the first dose of study treatment. 5. History of arterial or venous thrombosis (eg, stroke, transient ischemic attack, pulmonary embolism, or deep vein thrombosis). 6. Live and live-attenuated vaccines are prohibited within 28 days prior to the first dose of study treatment. 7. History of solid organ transplant. 8. Anti-tumor therapy (chemotherapy, antibody therapy, molecular targeted therapy, hormonal therapy, or investigational agent) within 28 days of first dose of study treatment. 9. Presence or history of any of the following viral infections: HIV, Hepatitis C, Hepatitis B, and active severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). 10. Toxicities from prior anti-tumor therapy (including radiotherapy) not having improved to at least Common Terminology Criteria for Adverse Events (CTCAE) version 5.0 grade 1. 11. Therapeutic or palliative radiation therapy within 2 weeks of first dose of study treatment. 12. Major surgery within 28 days of first dose of study treatment. 13. History or evidence of any other clinically significant disorder, condition, or disease that, in the opinion of the investigator, would pose a risk to participant safety.
