Brief Summary:
This is an open-label, multi-center, dose-escalation and dose-expansion phase I study to evaluate the safety, tolerability, PK characteristics and anti-tumor activity of PARP inhibitor IMP4297 and temozolomide combination therapy in patients with advanced solid tumors and with ES-SCLC who develops disease progression after 1L platinum-based regimen.

Condition or disease Intervention/treatment Phase
Advanced Solid Tumours Small Cell Lung Cancer Drug: IMP4297 Phase 1

Detailed Description:
This study will be conducted in two parts. Part I of the study will be dose escalation evaluation to determine the MTD and/or RP2D of IMP4297 in combination with temozolomide. Part II of the study will be conducted in two RP2D expansion cohorts (sensitive ES-SCLC cohort and resistant ES-SCLC cohort) to further evaluate the anti-tumor activity, safety and tolerability of this regimen in ES-SCLC patients.

Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  1. The patient must voluntarily participate in this clinical study and be willing and able to provide written informed consent/assent for the trial.
  2. Age ≥ 18 years old on the day of signing informed consent form (ICF), males or females
  3. Patient population:

    1. In Part I: The patient must have histologically or cytologically confirmed advanced solid tumor that is refractory to standard treatment or for which no standard treatment exists, including but not limited to triple-negative breast cancer (TNBC), SCLC, ovarian cancer (OC) and metastatic castration-resistant prostate cancer (mCRPC).
    2. In Part II: The patients must be histologically or cytologically confirmed ES-SCLC with disease progression after one and only one course of 1L standard platinum-based therapy. Anti-PD-1 or anti-PD-L1 antibody therapy is acceptable as long as it's part of the 1L treatment. Including platinum sensitive and platinum resistant patients. Platinum sensitive is defined as the relapse-free interval exceeds 90 days after treatment with platinum doublets is completed; The platinum resistant represents disease relapses within 90 days of treatment completion during a chemotherapy-free interval (CFI).
    3. In Part I: Patients have an ECOG performance status of 0 to 1.
    4. In Part II: Patients have an ECOG performance status of 0 to 2.
    5. Patients have a life expectancy of ≥12 weeks.
    6. In Part II: patients have at least 1 measurable lesion per RECIST v1.1, including a previously irradiated lesion if has progressed since radiotherapy, that can be accurately measured at baseline which is suitable for accurate repeated measurements
  4. Patients have adequate organ function, as indicated by the following laboratory values (had not received blood transfusion, apheresis infusion, erythropoietin, granulocyte colony-stimulating factor, and other relevant medical support within 28 days before the administration of the IPs
  5. Female patients should meet at least 1 of the following criteria before they can participate in the study:

    • Females who have no childbearing potential (i.e., physiologically incapable of pregnancy), including those who have undergone hysterectomy, bilateral oophorectomy, or bilateral salpingectomy.
    • Post-menopausal (total cessation of menses for ≥1 year).
    • For those with childbearing potential, they should have a negative serum pregnancy test during the screening period (within 7 days prior to the first dose of the IPs), should not be in lactation, and willing to take effective contraceptive measures throughout the study period, from study entry up to 6 months after the last dose of the IP(s).
  6. Male patients are eligible to participate in the study if they have undergone vasectomy or agree to use effective methods of contraception from study entry up to 6 months after the last dose of the IP(s).

Exclusion Criteria:

  1. Patients with primary tumor in central nervous system (CNS) and active or untreated central CNS metastases and/or carcinomatous meningitis should be excluded. Patients with previously treated brain metastases may participate provided they are clinically stable for at least 4 weeks and, have no evidence of new or enlarging brain metastases and no requirements for corticosteroids 14 days prior to dosing with IPs.
