A PHASE 1 DOSE ESCALATION AND EXPANSION STUDY EVALUATING THE SAFETY, TOLERABILITY, PHARMACOKINETICS, PHARMACODYNAMICS AND ANTI TUMOR ACTIVITY OF PF-07062119 IN PATIENTS WITH ADVANCED GASTROINTESTINAL TUMORS

Number of Participants With Dose Limiting Toxicities (DLTs) Assessed Through Cycle 1

时间窗: 28 Days

Hematological DLTs: * Grade 3 neutropenia lasting \>5 days * Febrile neutropenia defined as an ANC \<1.0 x 10 ̂9/L with a single temperature of \>38.3°C, or a sustained temperature of ≥38°C, for more than 1 hour * Grade ≥3 Neutropenia with infection * Grade 3 Thrombocytopenia with Grade ≥2 (clinically significant) bleeding * any Grade 4 Thrombocytopenia * Anemia or Thrombocytopenia requiring transfusion Non Hematological DLTs: * Grade ≥3 fatigue lasting ≥7 days * for participants with liver, bone, or lung metastasis, an AST or ALT increase \>8 x ULN or ALP \>10 x ULN; * confirmed DILI meeting Hy's law criteria * Grade 3 Vomiting or Diarrhea lasting ≥3 days despite adequate treatment/other supportive care * Grade 4 Vomiting or Diarrhea * Grade ≥3 CRS regardless of duration * Grade ≥3 QTcF prolongation irrespective of duration * any death not clearly due to underlying disease or extraneous causes Clinically important/persistent toxicities were DLTs reviewed by investigators and sponsor.

Number of Participants With All-Causality Treatment-Emergent Adverse Events (TEAEs),Treatment-Emergent Serious Adverse Events (TESAEs), Maximum Grade 3 or 4 and 5 TEAEs

时间窗: 4 Years

An AE was any untoward medical occurrence in a participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. An SAE was defined as any untoward medical occurrence that, at any dose: resulted in death; was life threatening; required inpatient hospitalization or prolongation of existing hospitalization; resulted in persistent disability/incapacity; was a congenital anomaly/birth defect, etc. Treatment-emergent events were with onset date occurring during the on-treatment period. AEs were documented and recorded at each visit using the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) version 5.0.

Number of Participants With Treatment-Related TEAEs, TESAEs, Maximum Grade 3 or 4 and 5 TEAEs

时间窗: 4 Years

An AE was any untoward medical occurrence in a participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. An SAE was defined as any untoward medical occurrence that, at any dose: resulted in death; was life threatening; required inpatient hospitalization or prolongation of existing hospitalization; resulted in persistent disability/incapacity; was a congenital anomaly/birth defect, etc. Treatment-emergent events were with onset date occurring during the on-treatment period. Relatedness to study treatment was determined by the investigator. AEs were documented and recorded at each visit using the NCI CTCAE version 5.0. Severe AEs were classified as Grade 3; life-threatening consequences and urgent intervention indicated were classified as Grade 4; deaths related to AEs were classified as Grade 5.

Number of Participants With CTCAE Grade 3 or 4 Hematology Laboratory Abnormalities

时间窗: 4 Years

The investigator reviewed the laboratory report, documented this review, and recorded any clinically relevant changes occurring during the study in the AE section of the CRF. Clinically significant abnormal laboratory findings were those which were not associated with the underlying disease, unless judged by the investigator to be more severe than expected for the participant's condition. CTCAE version 5.0 was applied.
