Clinical Trial Summary

HS-10241, an oral and highly selective MET-TKI, may contribute to overcoming common acquired MET-based resistance mechanisms following prior EGFR-TKI monotherapy. This study is conducted to evaluate the efficacy and safety of HS-10241 combined with Almonertinib versus platinum-based chemotherapy in NSCLC with MET amplification after failure of EGFR-TKI treatment.

Description:

This is a phase 3, randomized, open-label, multicenter study to evaluate the efficacy and safety of HS-10241 in combination with Almonertinib versus platinum-based chemotherapy in patients with MET-amplified locally advanced or metastatic NSCLC who have progressed after prior EGFR-TKI therapy. All eligible patients were randomly assigned to experimental group (HS-10241 combined with Almonertinib) or control group (pemetrexed combined with platinum) at a ratio of 1:1. Patients in experimental group will receive HS-10241 300mg twice daily (BID) combined with Almonertinib 110mg once daily (QD) orally and will continue treatment until disease progression or other criteria for treatment discontinuation will be met. Patients in control group will receive the standard chemotherapy treatment of cisplatin/carboplatin combined with pemetrexed for 4~6 cycles. Participants will continue receive pemetrexed monotherapy until disease progression or other criteria for treatment discontinuation will be met. The efficacy and safety of the two groups will be evaluated after follow-up.

7. Currently receiving drugs known to prolong QT interval or may cause torsade de pointe; or requiring treatment with these drugs during the study.

2. Any unresolved toxicities from prior therapy greater than Grade 2 according to Common Terminology Criteria for Adverse Events (CTCAE) 5.0 with the exception of alopecia or neurotoxicity.

3. History of other primary malignancies.

4. Inadequate bone marrow reserve or organ function, as demonstrated by any of the

following laboratory values:

5. One or both of Alanine aminotransferase (ALT) and Aspartate aminotransferase (AST) > 2.5 × upper limit of normal (ULN) or > 5 × ULN in the presence of liver metastases.

6. Creatinine > 1.5 × ULN concurrent with creatinine clearance < 50 mL/min; confirmation of creatinine clearance is only required when creatinine is > 1.5 × ULN.

7. International normalized ratio (INR) > 1.5, and partially activated prothrombin time (APTT) > 1.5 × ULN.

8. Serum albumin (ALB) < 28 g/L

5. Any of the following cardiac criteria:

1. Resting corrected QT interval (QTc) > 470 ms obtained from electrocardiogram (ECG), using the screening clinic's ECG machine and Fridericia's formula for QT interval correction (QTcF).

2. Left ventricular ejection fraction (LVEF) = 50%.

6. Severe, uncontrolled or active cardiovascular diseases.

7. Diabetes ketoacidosis or hyperglycemia hypertonic occurring within 6 months before the date of randomization, or the glycosylated hemoglobin value = 7.5% in the screening period.

8. Severe or poorly controlled hypertension.

13. Judgment by the investigator that the patient should not participate in the study if the patient is unlikely to comply with study procedures, restrictions, and requirements.

14. Any disease or condition that, in the opinion of the investigator, would compromise the safety of the patient or interfere with study assessments.
