phase 1/2 study of hs-10376 in patients with non-small cell lung cancer

Conditions: Advanced Non-Small-Cell Lung Cancer

Summary: hs-10376 is an oral, highly selective, small molecular inhibitor of egfr/her2 exon 20 insertion mutation. this study will evaluate the safety, tolerability, pharmacokinetics and clinical activity of hs-10376 in chinese advanced non-small cell lung cancer (nsclc) patients.

this is a phase 1/2, first-in-human, open-label, multicenter study of hs-10376, this study has two parts: phase 1 and phase 2. the phase 1 portion consists of dose escalation and dose expansion, which is aimed to assess the safety and tolerability of hs-10376 in subjects with advanced nsclc and evaluate the preliminary efficacy of hs-10376. phase 2 will be conducted to evaluate the efficacy of hs-10376 in subjects with locally advanced or metastatic nsclc with a egfr exon 20 insertion mutation.

Eligibility criteria:
inclusion criteria: 1. men or women greater than or equal to 18 years 2. locally advanced or metastatic nsclc patients confirmed by histology or cytology, for which standard treatment is invalid, unavailable or intolerable 3. pathological, tumor tissue samples can be used to test egfr/her2 exon 20 insertion mutation by central laboratory for subjects 4. at least one measurable lesion in accordance with recist 1.1 5. eastern cooperative oncology group (ecog) performance status: 0\~1 6. estimated life expectancy \>12 weeks 7. reproductive-age women agree to use adequate contraception and cannot breastfeed while participating in this study and for a period of 6 months after the last dose. likewise, men also consent to use adequate contraceptive method within the same time limit. 8. females must have the evidence of non-childbearing potential 9. signed and dated informed consent form exclusion criteria: 1. treatment with any of the following: * previous or current treatment with egfr exon 20 insertion inhibitors, her2 exon 20 insertion inhibitors or egfr/her2 exon 20 insertion inhibitors * any cytotoxic chemotherapy, anticancer chinese medicine and targeted small molecule inhibitors within 14 days of the first dose of hs-10376 * any investigational agents and large molecule antibodies within 28 days of the first dose of hs-10376 * local radiotherapy for palliation within 2 weeks of the first dose of hs-10376, or patients received more than 30% of the bone marrow irradiation, or large-scale radiotherapy within 4 weeks of the first dose of hs-10376 * major surgery (including craniotomy, thoracotomy, or laparotomy, etc.) within 4 weeks of the first dose of hs-10376 2. inadequate bone marrow reserve or serious organ dysfunction 3. uncontrolled pleural, ascites or pericardial effusion 4. untreated, symptomatic or active central nervous system metastases 5. severe or poorly controlled hypertension 6. immunodeficiency disease and active infectious disease 7. refractory nausea, vomiting, or chronic gastrointestinal diseases, or inability to swallow oral medications 8. history of hypersensitivity to any active or inactive ingredient of hs-10376 or to drugs with a similar chemical structure or drugs belonging to the same category of hs-10376 9. the subject who is unlikely to comply with study procedures, restrictions, or requirements judged by the investigator 10. the subject whose safety cannot be ensured or study assessments would be interfered judged by the investigator 11. pregnant women, breastfeeding women or woman who has a child-bearing plan during the study 12. history of neuropathy or mental disorders, including epilepsy and dementia
