Brief Summary:
Phase 1b clinical study to evaluate the PK of oral AZD4547 in Chinese patients and RP2D. Phase 2 study to evaluate the efficacy of AZD4547 in urothelial carcinoma patients with FGFR2/3 gene alterations.

Condition or disease Intervention/treatment Phase
Urothelial Carcinoma Drug: AZD4547 Phase 1 Phase 2

Detailed Description:
This study is an open-label, Phase 1b/2 clinical study. In the Phase 1b study, the safety and tolerability of AZD4547 in patients with advanced solid tumors will be evaluated, the PK of oral AZD4547 in Chinese patients and the recommended phase 2 dose (RP2D) will be determined, and the antitumor activity will be preliminarily assessed. In the Phase 2 study, the efficacy of AZD4547 at the recommended dose in patients with locally advanced or metastatic urothelial carcinoma with FGFR2/3 gene alterations (including mutations and/or fusions) will be evaluated, and the safety, tolerability, and PK of AZD4547 will be further evaluated.

Arm Intervention/treatment
Experimental: Urothelial Carcinoma with FGFR2/3 Gene Alterations
Evaluate the Efficacy of AZD4547 in Urothelial Carcinoma Patients with FGFR2/3 Gene Alterations

In Phase 1b study, subjects will receive continuous twice daily dosing in 21-day cycles (no matter if missed doses or delays exist), with pre-set dose cohorts of 80 mg BID and 120 mg BID.

In Phase 2, subjects will receive continuous twice daily dosing in 21-day cycles with the RP2D or other doses as determined by the investigator and sponsor.

Other Name: ABSK091




Primary Outcome Measures :
  1. DLT [ Time Frame: 21 days ]
    Incidence of dose limiting toxicity (DLT)

  2. AEs and SAEs [ Time Frame: at least 6 months ]
    Incidence and grade of adverse events (AEs), serious adverse events (SAEs) and adverse events of special interest (AESI) (based on Common Terminology Criteria for Adverse Events, CTCAE 5.0) .

  3. ORR [ Time Frame: 6 months ]
    To confirm objective response rate (assessed by RECIST 1.1) in FGFR2/3 gene altered (including mutations and/or fusions) subjects with locally advanced or metastatic urothelial cancer with treated with AZD4547


Secondary Outcome Measures :
  1. DOR [ Time Frame: at least 6 months ]
    Duration of response (DoR): The time from the first evaluation of [CR] or [PR] until disease progression;

  2. DCR [ Time Frame: at least 6 months ]
    Disease control rate (DCR): DCR = [CR] + [PR] + stable disease [SD];

  3. PFS [ Time Frame: at least 6 months ]
    Progression-free survival (PFS): time to progression or death from the first day subjects receive AZD4547;

Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  1. Aged ≥ 25, both male and female;
  2. Patients with histologically confirmed, surgically unresectable locally advanced or metastatic uroepithelial carcinoma that may be accompanied by other histologic differentiation (<50% of the total, including adenoid, squamous, or more aggressive sarcomatoid/micropapillary differentiation)
  3. ECOG PS (performance status) score of 0-2;
  4. Expected survival of ≥ 3 months;
  5. Acceptable organ functions satisfy the following laboratory test requirements, and the test results should be obtained within 14 d prior to the first dose for study treatment (no transfusion of blood or blood products within 14 d prior to the blood test and no correction with bone marrow hematopoietic stimulating factors):
  6. Female or male subjects of childbearing potential must agree to take medically approved measures for contraception during and for 6 months after the end of the study treatment; female subjects of childbearing potential must have a negative blood β-HCG test within 7 d prior to first dosing and must be non-lactating;
  7. Subjects must voluntarily participate in this clinical trial, understand the study procedures and be able to sign an informed consent form in writing.

Exclusion Criteria:

  1. Known to be allergic to AZD4547 tablets or constituents;
  2. Subjects have previously received selective FGFR inhibitors (in the case of multi-target inhibitors including FGFR, it is required to discuss with the sponsor to decide whether they can be included);
  3. There have been other malignancies requiring treatment in the past 2 years (except for cured skin cancer, cervical carcinoma in situ, basal cell carcinoma, focal prostate cancer with a Gleason score of 6, and focal prostate cancer at low risk of recurrence with a Gleason score of 3+4 and treated for more than 6 months at screening);
  4. There are unstable (those who clinically/radiologically stable for at least 4 weeks prior to signing the ICF and requiring no long-term corticosteroid treatment may be enrolled) or symptomatic CNS metastases (other than pia mater metastases), or pia mater metastases of any condition;
  5. The investigator determines that there are significant factors influencing oral drug absorption, such as inability to swallow complete pills, any type of uncontrollable nausea and vomiting, residual stomach dysfunction after total gastrectomy or subtotal gastrectomy, short bowel syndrome after small bowel resection, active diarrhea or irritable bowel syndrome requiring medical attention;
