About this study

This is a multicenter, open-label, Phase Ib clinical trial of HS-20117 combination therapies to evaluate the safety, tolerability, efficacy, PK profile and immunogenicity in participants with advanced solid tumors. The study includes a dose escalation part and a dose expansion part. The dose-escalation study will be performed to evaluate the safety, tolerability, PK profile, immunogenicity, and efficacy of HS-20117 combination therapies in participants with advanced solid tumor. The subsequent dose-expansion study will be performed to evaluate the efficacy of HS-20117 combination therapies in participants with locally advanced or metastatic NSCLC harboring EGFR exon 20 insertion mutations or EGFR classical mutations, and RAS/BRAF V600E wild type CRC.

Primary outcomes

  1. Incidence and severity of treatment-emergent adverse events

    Time frame: rom the date of first dose to 90 days after the final dose.

    Adverse event (assessed according to NCI CTCAE v5.0) is defined as any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship.

  2. Tolerability of HS-20117 combination therapy: incidence of DLT events, maximum tolerated dose (MTD) or maximum applicable dose (MAD) of HS-20117 in combination therapies.

    Time frame: From the date of first dose to day 21.

    MTD is defined as the previous dose level at which 2 or more out of 2-6 subjects experienced a DLT. MAD is defined as follows: a) based on PK data, it is anticipated that at this dose level, the dose-exposure plateau has been reached, b) based on existing safety data, it is judged that dose escalation following this dose level will have a large safety risk or subject intolerance, or c) based on the PK-PD model, it suggested that the optimal target concentration of safety and efficacy has been explored.

Secondary outcomes

  1. Efficacy of HS-20117: Objective response rate (ORR)

    Time frame: From the date of first dose to the date of disease progression or withdrawal from study, approximately 2 years

    ORR is defined as the percentage of participants with BOR of confirmed CR or confirmed PR per RECIST v1.1

  2. Efficacy of HS-20117: disease control rate (DCR)

    Time frame: From the date of first dose to the date of disease progression or withdrawal from study, approximately 2 years

    DCR is defined as the percentage of patients who have a best overall response (confirmed CR, PR, or stable disease for at least 6 weeks) per RECIST v1.1.

  3. Efficacy of HS-20117: duration of response (DoR)

    Time frame: From the date of first dose to the date of disease progression or withdrawal from study, approximately 2 years

    DoR only applies to participants whose best overall response is CR or PR based on assessment per RECIST v1.1. The start date is the date of first documented response of CR or PR (i.e. the start date of observed response, not the date when response was confirmed), and the end date is defined as the date of the first documented progression or death due to underlying disease.

  4. Efficacy of HS-20117: progression free survival (PFS)

    Time frame: From the date of first dose to the date of disease progression or withdrawal from study, approximately 2 years

    PFS is defined as the time from the date of randomization or first dose (if randomization is not needed) to the date of the first documented progression or death due to any cause. PFS will be assessed per RECIST v1.1.

  5. Efficacy of HS-20117: overall survival (OS)

    Time frame: From the date of first dose to the date of disease progression or withdrawal from study, approximately 2 years

    OS is defined as the time from the date of randomization or first dose (if randomization is not needed) to the date of death due to any cause. For each participant who is not known to have died as of the cutoff date for overall survival analysis, OS time was censored on the last date the participant is known to be alive.

  6. PK parameters: Trough serum concentration (Ctrough) of HS-20117 and HS-20093

    Time frame: From the date of first dose to 90 days after the final dose.

    Ctrough is the observed serum concentration immediately prior to the next administration.

  7. PK parameters: Time to reach maximum observed serum concentration (Tmax) of HS-20117

    Time frame: From the date of first dose to 90 days after the final dose.

    The Tmax is defined as time to reach maximum observed serum concentration of HS-20117.

  8. PK parameters: Area under the curve from time Zero to end of dosing interval (AUCtau) of HS-20117

    Time frame: From the date of first dose to 90 days after the final dose.

    The AUCtau is defined as the area under the serum concentration-time curve during a dose interval time period (tau).

  9. PK parameters: Maximum serum concentration (Cmax) of HS-20117 and HS-20093.

    Time frame: From the date of first dose to 90 days after the final dose.

    The Cmax is the maximum observed serum concentration of HS-20117, HS-20093.

  10. Immunogenicity of HS-20117

    Time frame: From the date of first dose to 90 days after the final dose.

    Immunogenicity will be measured by the number of participants that are ADA positive.
