Details and patient eligibility

About

This study is conducted to determine the safety, tolerability, pharmacokinetics and anti-tumor activity of HS-10241 when given together with Almonertinib in patients with EGFRm+ advanced NSCLC.

Full description

This is a phase Ⅰb, multicenter study to evaluate safety, tolerability, pharmacokinetics, and efficacy of HS-10241 administered orally in combination with Almonertinib in patients with EGFRm+ locally advanced or metastatic NSCLC who have progressed following prior EGFR-TKI therapy.

The study consist of two parts: Part 1 is the dose escalation period to observe the safety, tolerance, PK characteristics and preliminary anti-tumor activity, and determine the maximum tolerated dose (MTD) or maximum applicable dose (MAD) of combined administration; Part 2 is the dose expansion period to select appropriate doses in different target populations and further evaluate the efficacy, safety, tolerance and PK characteristics of combined administration, and determine the phase II recommended dose (RP2D).

All patients will be carefully followed for adverse events during the study treatment and for 28 days after the last dose of study drug. Patients of this study will be permitted to continue therapy with assessments for progression once every 8 weeks, if the product is well tolerated and the subject has stable disease or better. Survival follow-up is recommended once every 12 weeks.

Patients histologically or cytologically confirmed with locally advanced or metastatic NSCLC.
According to Recist1.1, at least 1 target lesion that should be measurable lesions without local treatment like irradiation or with definite progression after local treatment and can be accurately measured at baseline as ≥ 10 mm in the longest diameter (except lymph nodes, which must have short axis ≥ 15mm)
ECOG performance status of 0-1with no deterioration within 2 weeks before enrollment.
Estimated life expectancy ≥three months.
Females of child bearing age should adapt adequate contraceptive measures and should not be breastfeeding from the signing of informed consent to 6 months after the last treatment of the study. Male patients should be willing to use barrier contraception (i.e., condoms) from the signing of informed consent to 6 months after the last treatment of the study.
Females must have a negative pregnancy test in 7 days prior to start of first dose if of childbearing potential or must have evidence of non-childbearing potential by fulfilling any one of the following criteria:
1. Postmenopausal defined as age more than 60 years and amenorrheic for at least 12 months following cessation of all exogenous hormonal treatments.
2. Women under 60 years old would be considered postmenopausal if they have been amenorrheic for 12 months or more, following cessation of exogenous hormonal treatments, and with luteinizing hormone (LH) and follicle-stimulating hormone (FSH) levels in the postmenopausal range for the laboratory.
3. Documentation of irreversible surgical sterilization by hysterectomy, bilateral oophorectomy, or bilateral salpingectomy, but not by tubal ligation.
Signed and dated Informed Consent Form. Specific inclusion criteria Part 1 Patients have previously received any EGFR TKI continuous treatment (such as Gefitinib, Erlotinib, Osimertinib or Almonertinib) and had disease progression by imaging recorded. Before the first dose, all patients must provide imaging evidence of disease progression during or after the last treatment period. Before the start of study treatment, patients need to provide all the following test results detected by tumor biopsy tissue or blood samples with disease progression during or after the last treatment: EGFR sensitive mutation (either exon 19 deletion or L858R mutation); T790M status (negative or positive). The above test results of local laboratories can be accepted without confirmation of the central laboratory. If there are no local laboratory test results, then tumor tissue or blood samples meeting the protocol requirements should be sent to the central laboratory for testing and the results should be obtained before the first dose of study drug.

Part2 Cohort 1 -Patients have previously received the 1st/2nd/3rd-generation EGFR TKI (only one kind of them) and had disease progression by imaging recorded with centrally confirmed EGFR mutation, T790M negative and MET-positive.

Cohort2- Patients have not received any systemic treatment of advanced NSCLC with centrally confirmed EGFR mutation and MET-positive.

Cohort3- Patients have previously received both 1st/2nd and 3rd-generation EGFR-TKI and had disease progression by imaging recorded with centrally confirmed EGFR mutation and MET-positive.

Cohort4-Patients have previously received the 1st/2nd-generation EGFR TKI continuous treatment (not received the 3rd-generation EGFR TKI treatment) and had disease progression by imaging recorded with centrally confirmed EGFR mutation, T790M positive and MET-positive.

*Definition of MET-positive (any one of the following): ① Fluorescence in situ hybridization (FISH): MET gene copy number ≥ 5 or MET/CEP7 ratio ≥ 2; ② Immunohistochemistry (IHC): ≥ 50% tumor cells MET 3+.
