Brief Summary

This open-label Phase Ib study will evaluate the safety, tolerability, and preliminary effectiveness of IN10018 in combination with dalpiciclib in adults with progressive meningiomas. Progressive meningiomas are tumors arising from the membranes surrounding the brain that have continued to grow or have returned after previous treatment. Participants will receive both study drugs by mouth in 28-day treatment cycles. IN10018 will be taken once daily throughout each cycle, and dalpiciclib will be taken once daily for 21 days followed by 7 days without dalpiciclib. Treatment may continue until the tumor progresses, unacceptable side effects occur, or another reason for stopping treatment applies. The study includes a dose-confirmation phase and a dose-expansion phase. The main goals are to evaluate side effects and determine a recommended dose of the combination for further study. Researchers will also assess whether the treatment can shrink tumors or delay tumor growth, measure how the drugs are processed in the body, and explore tumor and blood biomarkers that may be associated with treatment response.

Conditions

Meningioma; CDK4/6 Inhibitor

Outcome Measures

Primary Outcomes (2)

• Incidence of Dose-Limiting Toxicities (DLTs)

  The number and percentage of participants who experience at least one protocol-defined dose-limiting toxicity during Cycle 1. Dose-limiting toxicities will be assessed according to the National Cancer Institute Common Terminology Criteria for Adverse Events, version 5.0, and must be considered related to IN10018 and/or dalpiciclib.

  Dose-limiting toxicities will be assessed at the end of Cycle 1 (each cycle is 28 days).

• Incidence of Treatment-Emergent Adverse Events

  Number and percentage of participants who experience treatment-emergent adverse events, treatment-related adverse events, serious adverse events, Grade 3 or higher adverse events, or adverse events resulting in treatment interruption, dose reduction, or permanent treatment discontinuation. Adverse events will be graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events (CTCAE), version 5.0.

  Adverse events will be assessed from the first dose through 30 days after the last dose of study treatment, up to approximately 24 months.

Secondary Outcomes (6)

• Objective Response Rate (ORR)

  From first dose until disease progression, initiation of new anticancer therapy, withdrawal, death, or study completion, up to 36 months.

• Six-Month Progression-Free Survival Rate (PFS-6)

  At 6 months after the first dose.

• Disease Control Rate (DCR)

  From first dose until disease progression, withdrawal, death, or study completion, up to 36 months.

• Duration of Response (DoR)

  From first documented response until disease progression or death, up to 36 months.

• Progression-Free Survival (PFS)

  From first dose until disease progression or death, up to 36 months.

Study Arms (1)

IN10018 Plus Dalpiciclib

EXPERIMENTAL

Participants will receive oral IN10018 in combination with oral dalpiciclib in 28-day treatment cycles. IN10018 will be administered once daily continuously at 100 mg, with a permitted reduced dose of 50 mg. Dalpiciclib will be administered once daily at 125 mg on Days 1 through 21 of each cycle, followed by 7 days off treatment, with a permitted reduced dose of 100 mg. A modified 3+3 design will be used during dose confirmation to determine the recommended dose. Participants enrolled in the dose-expansion phase will receive the combination at the recommended dose. Treatment will continue until disease progression, unacceptable toxicity, withdrawal of consent, or another protocol-defined discontinuation criterion.

Drug: Ifebemtinib; Drug: Dalpiciclib

Interventions

Ifebemtinib DRUG

Ifebemtinib (IN10018) is an investigational oral focal adhesion kinase inhibitor. It will be administered once daily continuously during each 28-day treatment cycle. The starting dose is 100 mg once daily. If the starting dose is not tolerated, the dose may be reduced to 50 mg once daily. Ifebemtinib will be administered in combination with dalpiciclib until disease progression, unacceptable toxicity, withdrawal of consent, or another protocol-defined discontinuation criterion.

IN10018 Plus Dalpiciclib

Dalpiciclib DRUG

Dalpiciclib is an oral, selective cyclin-dependent kinase 4 and 6 inhibitor. It will be administered at a starting dose of 125 mg once daily on Days 1 through 21 of each 28-day treatment cycle, followed by 7 days without dalpiciclib. If the starting dose is not tolerated, the dose may be reduced to 100 mg once daily. Dalpiciclib will be administered in combination with ifebemtinib until disease progression, unacceptable toxicity, withdrawal of consent, or another protocol-defined discontinuation criterion.

• No available standard treatment option, or failure of standard treatment, including surgery, radiotherapy, or other systemic therapy.
• At least 24 weeks must have elapsed since completion of radiotherapy, including external beam radiation therapy, brachytherapy, or radiosurgery such as Gamma Knife or CyberKnife.
• At least one measurable lesion according to Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST 1.1), as confirmed by the investigator.
• Eastern Cooperative Oncology Group (ECOG) performance status of 0, 1, or 2. Estimated life expectancy of at least 3 months, as determined by the investigator.
• Adverse effects caused by previous treatments must have recovered to Grade 1 or lower according to the Common Terminology Criteria for Adverse Events (CTCAE), except for alopecia and fatigue.
• The dose of corticosteroids or other hormonal treatment must have been stable for at least 4 days before enrollment.
