Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a phase I/II study to evaluate the safety and tolerability, DLT(Dose limited toxicity), MTD(Maximum tolerated dose), and RP2D(Recommended phase II dose) of WJB001 capsules in patients with advanced solid tumors, including dose escalation phase, dose expansion phase and cohort expansion phase.The study includes screening, treatment and follow-up periods.

In the Dose Escalation phase:Accelerated titration (the first two dose groups) and "BOIN" combination (the subsequent dose group) were used for dose escalation.

In the Dose Expansion phase:Based on the previous data, 1 to 2 doses were selected to further evaluate the initial efficacy, safety, tolerability and pharmacokinetic characteristics to confirm RP2D.

In the Cohort Expansion phase:The preliminary plan of cohort expansion phase uses the Simon two-stage optimal method to expand 2 to 3 cohorts.

Group Type EXPERIMENTAL

WJB001

Intervention Type DRUG

Dose Escalation:

Accelerated titration (the first two dose groups) and "BOIN" combination (the subsequent dose group) were used for dose escalation.

Dose Expansion:

Based on the previous data, 1 to 2 doses were selected to further evaluate the initial efficacy, safety, tolerability and pharmacokinetic characteristics to confirm RP2D.

Cohort Expansion:

The preliminary plan of cohort expansion phase uses the Simon two-stage optimal method to expand 2 to 3 cohorts.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

1. ≥ 18 years or older at the time of informed consent；
2. Patient with advanced malignant solid tumors clearly diagnosed pathologically and/or cytologically, who have failed to receive standard treatment, or who currently no have standard treatment, or who are intolerant to standard treatment;
3. Eastern Cooperative Oncology Group (ECOG) Performance Status (PS) score ≤1;
4. Life expectancy ≥ 12 weeks;
5. Adequate hematologic and organ function；
6. All acute toxic effects from previous antineoplastic therapy or surgery ；
7. Fertile women must confirm a negative blood pregnancy test within 7 days prior to the first administration of study drug;and they required to use adequate and effective contraceptive measures throughout the treatment period and within 3 months after the end of treatment;Fertile women in this protocol were defined as sexually mature women: 1) not undergoing hysterectomy or bilateral oophorectomy; 2) 24 months without a continuous period of spontaneous menopause (i.e., having had a period at any time in the previous 24 consecutive months; Amenorrhea after cancer treatment does not exclude fertility). Male participants with a sexual partner who was a woman of reproductive age had to agree to use an effective contraceptive method while using the study drug and for 3 months after the last dose；

8. At least one measurable tumor lesion that meets the definition of RECIST v1.1, with no history of biopsy two weeks before screening(applicable to all stages);
9. Subjects with CCNE1 overexpression (H score \> 50) or amplification (DNA copy number \> 7)confirmed by central laboratory (applicable to the dose expansion stage and efficacy expansion stage);
10. For subjects with advanced uterine serous carcinoma, ≤2 lines of therapy for recurrence are allowed after first-line treatment; For subjects with advanced high-grade serous ovarian, fallopian tube, or peritoneal cancer,≤2 lines of therapy after platinum resistance are allowed(applicable to the dose expansion stage and efficacy expansion stage)；

Exclusion Criteria

1. Pregnant or lactating women;
2. Any known allergies to or contraindications to components of the study drug;
3. History of substance abuse;
4. History of alcohol abuse or consumption of more than 28 units of alcohol per week (1 unit =285 ml beer or 25 ml spirits (40%v/v) or 100 ml wine).

1. Previous or current treatment with Wee1 inhibitors;
2. Received cytotoxic chemotherapy drugs,anti-tumor traditional Chinese medicine orother anti-tumor therapies (such as small molecule targeted therapy, etc.)within 4 weeks prior to the first administration of study drug;Or received the investigational drug, macromolecular drug with anti-tumor effect (e.g., monoclonal antibody, antibody-drug conjugate, or bispecific antibody, etc.) within 28 days prior to the first administration of study drug; Or need to continue receiving these medications during the study;

7. Patients with active HBV and HCV infection: if HBsAg is positive or/and anti-HBc is positive, blood HBV DNA should be tested to confirm that it is above the limit of quantitative detection; If anti-HCV is positive, it is necessary to detect HCV RNA to confirm that the HCV virus copy number exceeds the quantitative detection limit；
8. Known history of human immunodeficiency virus infection or seropositivity for HIV;

10. History of other primary solid tumor (except a cured solid tumor that has been inactive for ≥5 years before screening and has a very low risk of recurrence）; Adequately treated non-melanoma skin cancer or lentigo maligna with no evidence of disease recurrence; Adequately treated carcinoma in situ with no evidence of disease recurrence, such as carcinoma in situ of the cervix);
