Study Overview

• Status: Not yet recruiting
• Conditions: Non-small Cell Lung Carcinoma
• Intervention / Treatment: Drug: BPI-361175

Detailed Description

This is a Phase I/II, open-label, non-randomized study to evaluate the safety, tolerability, pharmacokinetics, and anti-tumor activity of BPI-361175 tablets in patients with advanced NSCLC with EGFR C797S mutation and other EGFR-related mutations. Adult patients (18 and above) will receive a single dose of BPI-361175 followed by a 7-day washout period with continuous oral dosing of BPI-361175 in 28 days cycle.

This is a three-stage study, consisting of Phase Ia dose-escalation, Phase Ib dose expansion, and pivotal Phase II study.

It is expected to provide a brand-new treatment for advanced NSCLC. The study design utilizes a Bayesian Optimal Interval (BOIN) method to guide the dose level assignment of BPI-361175 and estimate the MTD/RP2D based on cumulative information on DLTs in the Cycle 0 + Cycle 1 of treatment.

Exclusion Criteria:

1. Presence of another active primary malignant tumors;
2. Unstable, symptomatic primary CNS tumors/metastasis or leptomeningeal metastases which are not suitable for enrollment, as judged by investigators.

3. Treatment with the most recent therapy (e.g., chemotherapy, immunotherapy, targeted therapy, radiation therapy, investigational therapy/agent) within 4 weeks or approximately 5 half-lives, whichever is the longer, before the first dose. (If sufficient wash-out time has not occurred due to schedule or PK properties, an alternative appropriate wash-out time based on known duration and time to reversibility of drug related adverse events could be agreed upon by the sponsor and investigators);
4. Gastrointestinal disorders that would affect oral swallowing or the investigators judge the absorption of the study drug will be interfered;
5. Use of strong or moderate CYP3A inhibitors or inducers within 7 days prior to the first dose;
6. Autologous (within 3 months) or allogeneic (within 6 months) organ or stem cell transplantation prior to the first dose; any major surgery or severe trauma (except biopsy sampling) within 4 months prior to the first dose;
7. Palliative radiation therapy within 2 weeks prior to the first dose;
8. Patients who have active viral hepatitis B (HBV) infection (exception: HBV DNA ≤ 500 IU/mL and has been stable for longer than 4 weeks);
9. Patients who have active infections that required systemic therapy within 1 week prior to the first dose;

10. Any of the following cardiac conditions within the last 6 months:

    Unexplained or cardiovascular cause of presyncope or syncope, tachycardia, ventricular fibrillation, or sudden cardiac arrest. Prolonged corrected QT interval [mean resting corrected QT interval QTcF > 450 msec for males or > 470 msec for females from 3 electrocardiogram (ECG)];

11. Any > CTCAE Grade 1 prior to the first dose;
12. Medical history of interstitial lung disease, drug-induced interstitial lung disease, radiation pneumonitis which required steroid treatment, or any evidence of clinically active interstitial lung disease, any uncontrolled systemic disease, and other serious illnesses;
13. Patients with deep venous thrombosis, pulmonary embolism or any other serious thromboembolism within 3 months prior to the first dose (implantable venous access-port, catheter-related thrombosis or superficial venous thrombosis is not considered as "serious" thromboembolism);
14. The presence of drug abuse and medical, psychological, or social conditions that do not permit compliance with the protocol or will not be available for protocol-required study visits or procedures.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Phase Ia Dose Escalation; The number of patients enrolled will be determined based on the maximum number required to establish the RP2D according to a Bayesian Optimal Interval (BOIN) method and will depend on the true DLT rate. Up to 24 patients will be enrolled for the dose-finding part.	Drug: BPI-361175; BPI-361175 is an oral fourth-generation EGFR inhibitor. The activation of EGFR signaling pathways is associated with various biological events such as proliferation, migration, differentiation, and apoptosis.
Experimental: Phase Ib Expansion Study; Based on clinical data obtained from Part 1a, up to 24 patients with advanced NSCLC harboring EGFR C797S mutation will be enrolled in this dose expansion part of the study. One or more dose levels may be investigated dependent on emerging data. The sample size will be determined based on practical considerations.	Drug: BPI-361175; BPI-361175 is an oral fourth-generation EGFR inhibitor. The activation of EGFR signaling pathways is associated with various biological events such as proliferation, migration, differentiation, and apoptosis.
Experimental: Phase II Study; The phase II part will be conducted using a Bayesian Optimal Phase 2 (BOP2) method with efficacy monitoring based on cumulative information on Objective Response Rate (ORR). The BOP2 method will consist of 2 interim looks occurring when the number of evaluable patients reaches the pre-specified values of 10 and 20 and a final analysis when a total of 30 patients are evaluable.	Drug: BPI-361175; BPI-361175 is an oral fourth-generation EGFR inhibitor. The activation of EGFR signaling pathways is associated with various biological events such as proliferation, migration, differentiation, and apoptosis.
