Brief Summary

This study is a prospective single-arm phase II clinical study. Advanced gastric and colorectal tumor patients with FGFR 1-3 alterations who have failed standard therapy will be enrolled in this study once they have signed the informed consent form (ICF) and been identified as eligible in screening. The patients will receive 13.5 mg of pemigatinib once a day (QD) orally following a 2-week administration/1-week interruption regimen. They will be dosed until disease progression or intolerable toxicity. During treatment, clinical tumor imaging evaluation will be performed according to RECIST v1.1 every 6 weeks (± 7 days) and then every 9 weeks (± 7 days) after week 48. Safety will be assessed according to NCI-CTCAE 5.0.

Conditions

Gastric and Colorectal Cancer

Outcome Measures

Primary Outcomes (1)

• objective response rate (ORR)

  ORR is defined as the proportion of subjects with complete response (CR) + those with partial response (PR) according to the RECIST1.1 criteria.

  an expected average of 2 years

Study Arms (1)

selective FGFR1-3 inhibitor

EXPERIMENTAL

Drug: pemigatinib

Interventions

pemigatinib DRUG

The patients will receive 13.5 mg (1 pill/time) of pemigatinib once a day (QD) orally following a 2-week administration/1-week interruption regimen, with 21 days as a cycle. They should take pemigatinib at regular times of the day to avoid the effects of inconsistent timing on plasma concentrations.

Eligibility Criteria

• Age: 18 Years+
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• Aged ≥ 18 years old;
• With histologically or cytologically confirmed advanced metastatic gastric adenocarcinoma or adenocarcinoma of the gastroesophageal junction, or colorectal adenocarcinoma;
• Have at least one measurable lesion according to RECIST v1.1;
• With histologically confirmed FGFR1-3 alterations, including but not limited to amplification, mutation, fusion/rearrangement, etc.;
• With disease progression after a standard therapy (first-line therapy for gastric cancer; second-line therapy for colorectal cancer);
• No previous use of small molecule multi-target inhibitors targeting the FGFR pathway in the front-line therapy (including but not limited to anlotinib, lenvatinib, sorafenib, apatinib, etc.);
• ECOG physical performance status score of 0-1;
• Expected survival time \> 3 months;
• For evidence of sufficient organ functions, the subjects shall meet the following laboratory parameters:
• \) Absolute neutrophil count (ANC) ≥ 1.5 x 109/L without use of granulocyte colony stimulating factor in recent 14 days; 2) Platelet count ≥ 100 × 109/L without blood transfusion in recent 14 days; 3) Hemoglobin \> 9 g/dL without blood transfusion or erythropoietin use in recent 14 days; 4) Total bilirubin ≤ 1.5 × upper limit of normal (ULN); or total bilirubin \> ULN, direct bilirubin ≤ ULN; 5) Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) ≤ 2.5 × ULN (ALT or AST ≤ 5 × ULN for patients with liver metastasis); 6) Blood creatinine ≤ 1.5 × ULN and creatinine clearance (calculated by Cockcroft-Gault formula) ≥ 50 mL/min; 7) Good coagulation function: international normalized ratio (INR) or prothrombin time (PT) ≤ 1.5 × ULN (For subjects receiving an anticoagulant therapy, PT within the range proposed for the anticoagulant drug is acceptable); 10. Women of childbearing potential shall obtain a negative result in the urine or serum pregnancy test performed within 3 days before the first dose of the investigational drug (cycle 1, day 1). If the urine pregnancy test result cannot be identified as negative, a blood pregnancy test is needed. Women of non-childbearing potential are defined as those who have not had menses for at least 1 year or who have undergone surgical sterilization or hysterectomy; 11. All subjects at risk of conception (including their partners) shall use contraceptives with an annual failure rate of less than 1% throughout the entire treatment period up to 120 days after the last dose of the investigational drug (or 180 days after the last dose of the chemotherapy drug).

You may not qualify if:

• Diagnosed with malignant tumors other than gastric cancer and colorectal cancer within 5 years before the first dose, excluding radically cured cutaneous basal cell carcinoma, cutaneous squamous cell carcinoma, and/or radically resected carcinoma in situ;
• Previously treated with selective FGFR inhibitors;
• Have received any other investigational drug treatment or participated in another interventional clinical trial within 28 days before the first dose of the investigational drug, or have received anti-tumor drug treatment within 28 days before the first dose of the investigational drug (including Chinese herbal medicine with anti-tumor indications);
• Have not recovered (i.e., reaching ≤ grade 1 or the baseline status, excluding asthenia and alopecia) from toxicity and/or complications caused by any intervention before the start of treatment;
• With known symptomatic central nervous system metastasis and/or carcinomatous meningitis. Subjects with previously treated brain metastases are eligible if the disease is stable (no imaging evidence of progression in at least 4 weeks prior to the first dose of study treatment), there is no evidence of new or enlarging brain metastases on repeated imaging, and corticosteroids are not required in at least 14 days prior to the first dose of study treatment. Patients with carcinomatous meningitis should be excluded regardless of their clinically stability;
• Known history of allotransplantation or allogeneic hematopoietic stem cell transplantation;
• Subjects with abnormal laboratory parameters listed below:
• Serum phosphate \> ULN;
• Serum calcium exceeds the normal range, or the calcium concentration corrected for serum albumin exceeds the normal range when serum albumin exceeds the normal range;
• Potassium level \< lower limit of normal (LLN); potassium levels can be corrected by supplements at screening.
• With known history of human immunodeficiency virus (HIV) infection or confirmed with positive immune test results;
• Presence of severe infection in the active phase or with poor clinical control;
• Pleural effusion, ascites, or pericardial effusion with obvious clinical symptoms that require drainage;
• Acute or chronic active hepatitis B or C infection; hepatitis B virus (HBV) DNA \> 2000 IU/mL or 104 copies/mL; hepatitis C virus (HCV) RNA \> 103 copies/mL; hepatitis B surface antigen (HbsAg) and anti-HCV antibody positive concurrently. Those who with relevant parameters lower than the above criteria after nucleotide antiviral treatment can be enrolled;
• With clinically significant or uncontrolled heart diseases, including unstable angina, acute myocardial infarction within 6 months before the first dose, grade III/IV congestive heart failure (New York Heart Association), and uncontrolled arrhythmia (subjects with pacemakers or with atrial fibrillation but well controlled heart rate are allowed);
