Clinical Trial Summary

HS-10365 is a small molecular, oral potent, selective RET inhibitor. The purpose of this study is to investigate the efficacy and safety of HS-10365 in Chinese advanced RET fusion-positive non-small cell lung cancer patients without any systemic therapy.

Description:

This is an open-label, single arm, multi-center Phase 2 study in participants with treatment-naïve locally advanced or metastatic RET fusion-positive non-small cell lung cancer, which is designed to investigate the anti-tumor activity, safety and pharmacokinetics (PK) of HS-10365 at the recommended phase 2 dose (RP2D). HS-10365 will be administered orally twice daily until the occurrence of disease progression, unacceptable adverse events, withdrawal of consent, death or the end of the study. Primary endpoint is objective response rate (ORR) by Independent Reading Committee (IRC). Secondary and exploratory objectives include evaluation of secondary efficacy endpoints, safety and PK in the study population.

Eligibility

Inclusion Criteria:

1. Men or women aged more than or equal to (=) 18 years.

2. Histologically or cytologically confirmed diagnosis of locally advanced or metastatic NSCLC with RET fusion-positive, including recurrent or initial diagnosed Stage IIIB-IIIC/IV NSCLC that is not suitable for radical surgery.

Exclusion Criteria:

1. Treatment with any of the following:

Additional validated oncogenic drivers in NSCLC if known. Previous or current treatment with selective RET inhibitors or multi-kinase Inhibitor of RET.

Prior systemic therapy for metastatic disease. Treatment (including chemotherapy or immunotherapy) in the adjuvant/neoadjuvant setting is permitted if it was completed at least 6 months prior to relapse.

Local radiotherapy for palliation within 2 weeks of the first dose of study drug, or patients received more than 30% of the bone marrow irradiation, or large-scale radiotherapy within 4 weeks of the first dose.

Major surgery (including craniotomy, thoracotomy, or laparotomy, etc.) within 4 weeks of the first dose of study drug.

2. Inadequate bone marrow reserve or serious organ dysfunction.

3. Uncontrolled pleural effusion or ascites or pericardial effusion.

4. Known and untreated, or active central nervous system metastases.

5. Active autoimmune diseases or active infectious disease

6. Refractory nausea, vomiting, or chronic gastrointestinal diseases, or inability to swallow oral medications.

7. History of severe allergic reaction, hypersensitivity to any active or inactive ingredient of HS-10365 or to drugs with a similar chemical structure or class to HS-10365.

8. The subject who is unlikely to comply with study procedures, restrictions, or requirements judged by the investigator.

9. The subject whose safety cannot be ensured or study assessments would be interfered judged by the investigator.

10. Pregnant women, breastfeeding women or woman who has a child-bearing plan during the study.

11. History of neuropathy or mental disorders, including epilepsy and dementia

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	ORR assessed by IRC	ORR is defined as the percentage of patients with a CR or PR that was confirmed at a subsequent scan at least 4 weeks later, as assessed according to RECIST version 1.1.	From the date of first occurrence of complete response (CR) or partial response (PR) on 2 consecutive occasions (=4 weeks), until the date of disease progression or withdrawal from study, whichever came first, up to 48 months.
Secondary	Disease Control Rate (DCR)	Objective response was assessed by RECIST 1.1 thereby to evaluate disease control rate. Disease control was de?ned as the percentage of patients who have a best overall response (confirmed CR, PR, or stable disease for at least 5 weeks).	From the first occurrence of confirmed CR or PR or SD until the date of disease progression or withdrawal from study, whichever came first, up to 48 months.
Secondary	Duration of response (DOR)	Duration of response (DOR)	From the date of the first dose to disease progression or death in patients who achieve CR or PR, whichever came first, up to 48months.
Secondary	Progression-free survival (PFS)	Progression of tumor was assessed by RECIST 1.1 thereby to evaluate progression free survival. Progression-free survival was de?ned as the time from date of ?rst dose until the documentation of objective PD or death from any cause in the absence of progression (whichever occurred first), regardless of whether they subsequently received non-study anti-cancer therapy.	From the date of the first dose until the date of disease progression or death from any cause, whichever came first, up to 48 months.
Secondary	Overall survival (OS)	Overall survival (OS)	The time from initial administration to death from any cause, up to 5 years.
Secondary	Incidence and severity of treatment-related adverse events	Assessed by number and severity of adverse events as recorded on the case report form, vital signs, laboratory variables, physical examination, electrocardiogram, and NCI CTCAE v5.0.	From the first dose until 28 days after the last dose
Secondary	Observed maximum plasma concentration (Cmax) of HS-10365	Cmax of HS-10365	At the firs of every Cycle from 1 to 12(each cycle is 28 days)
