Brief Summary

This is a phase I clinical, first-in-human study of SIGX1094R monotherapy. The goal of this trial is to evaluate the safety, tolerability, pharmacokinetics (PK), pharmacodynamics (PD), anti-tumor activity and food effect of SIGX1094R in patients with advanced solid tumors.

Detailed Description

The study consists of two parts: SIGX1094R dose escalation study; food effect and SIGX1094R multiple-dose expansion study.

Part of SIGX1094R dose escalation study:

• the primary objective is to evaluate the safety and tolerability of SIGX1094R, and to define the maximum tolerated dose (MTD) and recommended Phase II dose (RP2D).
• the secondary objective is to evaluate the PK profile and preliminary efficacy of SIGX1094R, and to explore the relationship between PD parameters and efficacy.

Part of food effect and SIGX1094R multiple-dose expansion study:

• the primary objective is to evaluate the food effect on PK profile of SIGX1094R.
• the secondary objective is to further evaluate the anti-tumor activity, safety and tolerability of SIGX1094R, and to further evaluate the relationship between PD parameters and efficacy.

If a fresh biopsy is required, procedures more invasive than a core biopsy or significant risk procedures for which the procedure-associated absolute risk of mortality or major morbidity in the patient's clinical setting and specific institution is 2% or higher, should not be utilized. The tumor tissue is used for pFAK status confirmation, without restriction on enrollment.

Women of reproductive age must have a negative blood pregnancy test result within 7 days prior to the first dose and promise to adhere to fully effective contraception or abstinence from the beginning of the screening period until 6 months after the last dose of study treatment; male patients must promise to adhere to fully effective contraception or abstinence from the beginning of the screening period until 6 months after the last dose of study treatment.

Exclusion Criteria

Patients who meet any of the following criteria cannot be enrolled in this study.

1. Patients with hypersensitivity to the active ingredient or excipient ingredient of SIGX1094R, or a history of severe allergy.

2. Patients who have received cytotoxic chemotherapeutic drugs or small molecule targeted drugs within 4 weeks prior to the first dose.

3. Anti-tumor endocrine therapy, radiotherapy, interventional embolization, radiofrequency, proton therapy, radioimmunotherapy, immunotherapy or other biotherapies within 4 weeks prior to the first dose (if 5 T1/2 of the drug/therapy used by the patient is confirmed to be < 4 weeks, 5 T1/2 shall prevail).

4. Patients who have received anti-tumor treatment with medicine/proprietary medicine within 2 weeks prior to the first dose. Note: This criterion is relevant to China study only.
