Detailed Description

This is an open-label, single-arm, phase 1, dose escalation study to evaluate the safety, tolerability, pharmacokinetics, and preliminary pharmacodynamic effect of EOC317 in patients with advanced solid tumors.

The study comprises a dose-escalation phase and a dose-expansion phase.

  1. Dose-escalation: using 3+3 design to evaluate the safety, tolerability, and pharmacokinetic profile of EOC317 at 5, 10, 20, 30, 45, 60 mg in patients with advanced solid tumors, and to determine the maximum tolerated dose (MTD) and recommended dose (RDE) for the dose expansion phase.
  2. Dose-expansion: based on PK profile in the dose escalation phase, the dose-expansion study will evaluate the safety, tolerability, and preliminary pharmacodynamic effect of the RDE for EOC317 in patients with advanced solid tumors.

Description

Inclusion Criteria:

  1. Patients is able to understand and willing to sign a written informed consent.
  2. Patients is willing to complete the study procedure and follow-up examinations.
  3. Male or female patients, 18 years old and above.
  4. Dose-escalation phase: patients with histopathologically or cytopathologically confirmed advanced malignant solid tumors, including bladder cancer, cholangiocarcinoma, gastric cancer, breast cancer; dose-expansion phase: patients with histopathologically or cytopathologically confirmed advanced urothelial cancer, cholangiocarcinoma, and hepatocellular carcinoma or other advanced solid tumor with confirmed FGFR alterations.
  5. Patients who have disease progression after previous standard of care therapy, or are unable to tolerate standard of care therapy, or have no available standard of care therapy.
  6. Dose-escalation phase: measurable or unmeasurable lesion is acceptable; dose-expansion phase: at least one measurable lesion.

    * In accordance with the response evaluation criteria in solid tumors (RECIST v1.1), measurable lesion is defined as the lesion with the longest diameter ≥10 mm and thickness scanned ≤5mm in CT or MRI. For lymph node lesion, its minor axis must be ≥15mm.

  7. ECOG score is 0-1.
  8. Expected survival is longer than 3 months.
  9. No serious hematological, hepatic, or renal abnormality, in accordance with the results of the following laboratory tests:

    • Hematology: neutrophil ≥1.5x10^9/L, platelet ≥75x10^9/L, hemoglobin ≥90 g/L;
    • Hepatic function: alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤ upper limit of normal x3.0; alkaline phosphatase (ALP) ≤ upper limit of normal x2.5; total bilirubin (TBIL) ≤upper limit of normal x1.5; If there is a liver tumor, hepatic function: alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤ upper limit of normal x5.0; If there is bone metastasis or a liver tumor, alkaline phosphatase (ALP) ≤ upper limit of normal x5.0;
    • Renal function: the creatinine clearance calculated by the Cockcroft-Gault formula must be ≥ 50 mL/min.
  10. All the adverse events is recovered to ≤ CTCAE grade 1 after previous systemic anti-tumor therapy (except alopecia and leukodermia; stable or ≤ CTCAE grade 2 neuropathy induced by previous anti-tumor therapy).
  11. Effective contraceptive measures during the treatment and within 6 months after the last dose for male and female patients.
  12. Dose-escalation phase: collection of tumor biopsy samples will be optional; dose-expansion phase: non-optional collection of tumor biopsy samples if the FGFR alteration is unknown during screening period;
  13. Dose-expansion phase: liver function rating Child-Pugh grade A or grade B ( score ≥7);
  14. Blood pressure is effectively controlled using 0 or 1 antihypertensive drugs, (blood pressure ≤150/90 mmHg), without replacing antihypertensive drugs within 1 week before day 1 of cycle 1;

Exclusion Criteria:

  1. Previous use of the drug against FGFR pathway.
  2. Having other malignant tumors other than the tumor treated in the study (exceptions: the malignant tumors cured with no recurrence within three years before enrollment in the study; completely resected basal cell and squamous cell carcinoma of skin; completely resected carcinoma in situ of any type).
  3. Invasion of original lesion to central nervous system (CNS) with symptoms, which is unstable and requires high-dose steroid (≥10 mg Dexamethasone or equivalent dose) to control it.
