Brief summary
This study will evaluate the safety, tolerability, and preliminary efficacy of EIK1004 (IMP1707) in participants with recurrent advanced/metastatic breast cancer, ovarian cancer, metastatic castrate resistant prostate cancer (mCRPC) and pancreatic cancer with deleterious/suspected deleterious mutations of select homologous recombination repair (HRR) genes. Condition or disease Intervention/treatment Phase Advanced Solid Tumors Drug: EIK1004 (IMP1707) Phase 1/Phase 2
Detailed description
This study will evaluate the safety, tolerability and preliminary efficacy of EIK1004 (IMP1707) as monotherapy in patients with recurrent, advanced/metastatic solid tumors. The study consists of 2 parts: Dose escalation and dose optimization. In dose escalation (Part1), the study will identify the maximum tolerated dose (MTD) or maximum achievable dose (MAD) in solid tumor. In dose optimization (Part 2), the study will further evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics, and anti-tumor activity of select doses of EIK1004 (IMP1707)
Interventions

Intervention model description
Groups of participants are assigned to receive interventions for dose escalation in up to 7 cohorts.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Number of Participants who experience a Dose-Limiting Toxicity (DLT) | (Timeframe: up to 28 days) | A DLT is defined as an event with toxicity including the type, severity, time of onset, time of resolution, and the probable association with study treatment that are not due to pre-existing conditions as defined by the Common Terminology Criteria for Adverse Events Version 5.0 (CTCAE 5.0). The number of participants who experience a DLT will be reported. |
| Number of participants with adverse events, treatment emergent adverse events or serious adverse events | (Time Frame: 1 month post last dose of EIK1004 (IMP1707) | Number of participants reporting adverse events or serious adverse events which include any abnormal clinical events, laboratory assessments outside of normal clinical range, abnormal vital signs observed, and any abnormal ECG parameters |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Pharmacokinetic parameters of EIK1004 (IMP1707) | Through study completion, up to 3 years | Peak plasma concentration (Cmax) |
| Objective Response (OR) | Through study completion, up to 3 years | Defined as participants who have a complete response \[CR\] or Participants who have a partial response \[PR\] by RECIST 1.1 (Solid tumor) and RANO-BM (brain metastasis), or CA-125 response per GCIG criteria (ovarian cancer), or PSA response per PCWG3 criteria. |
Other
| Measure | Time frame | Description |
|---|---|---|
| Pharmacodynamic changes due to EIK1004 (IMP1707) | Through study completion, up to 3 years | Cytokines will be measured using an ELISA assay. The concentration of cytokines in plasma samples collected from patients is being measured and will be reported as a quantified value (e.g ng/mL). The fold change in plasma cytokines over baseline will be measured and the relative change compared to pre-dose/baseline numbers. |
