About this study

The study has been designed as a Phase III trial and consists of 2 parts:

  • Randomized part will evaluate the efficacy and safety of JDQ443 as monotherapy in comparison with docetaxel. Participants randomized to docetaxel arm will have the opportunity to cross-over to JDQ443 at disease progression per RECIST 1.1 confirmed by BIRC.
  • Extension part will be open after final progression-free survival (PFS) analysis (if the primary endpoint has met statistical significance) to allow participants randomized to docetaxel treatment to crossover to receive JDQ443 treatment regardless of progression on docetaxel.

The study population will include adult participants with locally advanced or metastatic (stage IIIB/IIIC or IV) KRAS G12C mutant non-small cell lung cancer (by tissue or plasma as determined by a Novartis-designated central laboratory or accepted local tests) who have received prior platinum-based chemotherapy and prior immune checkpoint inhibitor therapy administered either in sequence or as combination therapy.

Approximately 360 participants will be randomized to JDQ443 or docetaxel in a 1:1 ratio stratified by prior line of therapy and ECOG performance status.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Participant has histologically confirmed locally advanced/metastatic (stage IIIB/IIIC or IV)
  • Participant has a KRAS G12C mutation present in tumor tissue or plasma prior to enrollment, as determined by a Novartis designated central laboratory or by accepted local tests.
  • Participants has received one prior platinum-based chemotherapy regimen and one prior immune checkpoint inhibitor therapy for locally advanced or metastatic disease
  • Participant has at least 1 evaluable (measurable or non-measurable) lesion by RECIST 1.1 at the screening visit.

Exclusion criteria

  • Participants who have previously received docetaxel (except if received in neoadjuvant or adjuvant setting with no progression within 12 months after the of end of treatment), or any other KRAS G12C inhibitor.
  • Participant has EGFR-sensitizing mutation and/or ALK rearrangement by local laboratory testing. Participants with other druggable alterations will be excluded if required by local guidelines.
  • Participant has known active central nervous system (CNS) metastases and/or carcinomatous meningitis
  • Participant has an history of interstitial lung disease or pneumonitis grade > 1.

Other inclusion/exclusion criteria may apply

Treatment and study plan

JDQ443

Drug

JDQ443 tablets, orally administered

docetaxel

Drug

docetaxel concentrated solution for infusion, intravenously administered

Primary outcomes

  1. Progression free survival (PFS)

    Time frame: Approximately up to 24 months

    PFS is the time from date of randomization/start of treatment to the date of event defined as the first documented progression or death due to any cause. PFS is based on central assessment and using RECIST 1.1 criteria.

Secondary outcomes

  1. Overall Survival (OS)

    Time frame: Approximately up to 33 months

    OS is defined as the time from date of randomization to date of death due to any cause

  2. Overall Response Rate (ORR)

    Time frame: Approximately up to 33 months

    ORR is defined as the proportion of patients with best overall response of complete response (CR) or partial response (PR) based on central and local investigator's assessment according to RECIST 1.1.

  3. Disease Control Rate (DCR)

    Time frame: Approximately up to 33 months

    DCR is defined as the proportion of participants with Best Overall Response (BOR) of Complete Response (CR), Partial Response (PR), Stable Disease (SD) or Non-CR/Non-PD.

  4. Time To Response (TTR)

    Time frame: Approximately up to 33 months

    TTR is defined as the time from the date of randomization to the date of first documented response (CR or PR, which must be confirmed subsequently)

  5. Duration of Response (DOR)

    Time frame: Approximately up to 33 months

    DOR is calculated as the time from the date of first documented response (complete response (CR) or partial response (PR)) to the first documented date of progression or death due to underlying cancer.

  6. Progression-Free Survival after next line therapy (PFS2)

    Time frame: Approximately up to 33 months

    PFS2 (based on local investigator assessment) is defined as time from date of randomization to the first documented progression on next line therapy or death from any cause, whichever occurs first.

  7. Concentration of JDQ443 and its metabolite in plasma

    Time frame: Approximately up to 33 months

    To characterize the pharmacokinetics of JDQ443 and its metabolite HZC320

  8. Time to definitive deterioration of Eastern Cooperative Group of Oncology Group (ECOG) performance status

    Time frame: Approximately up to 33 months

    Deterioration of Eastern Cooperative Oncology Group (ECOG) Performance Status (PS)

  9. Time to definitive 10-point deterioration symptom scores of chest pain, cough and dyspnea per QLQ-LC13

    Time frame: Approximately up to 33 months

    The EORTC QLQ LC13 is a 13-item, lung cancer specific questionnaire module, and it comprises both multi-item and single-item measures of lung cancer-associated symptoms (i.e. coughing, hemoptysis, dyspnea and pain) and side-effects from conventional chemo- and radiotherapy (i.e. hair loss, neuropathy, sore mouth and dysphagia). The time to definitive 10-point deterioration is defined as the time from the date of randomization to the date of event, which is defined as at least 10 points absolute increase from baseline (worsening), with no later change below the threshold or death due to any cause

  10. Time to definitive 10-point deterioration in global health status/QoL, shortness of breath and pain per QLQ-C30

    Time frame: Approximately up to 33 months

    The EORTC QLQ-C30 is a questionnaire developed to assess the health-related quality of life of cancer participants. The questionnaire contains 30 items and is composed of both multi-item scales and single-item measures based on the participants experience over the past week. These include five domains (physical, role, emotional, cognitive and social functioning), three symptom scales (fatigue, nausea/vomiting, and pain), six single items (dyspnea, insomnia, appetite loss, constipation, diarrhea and financial impact) and a global health status/HRQoL scale. The time to definitive 10-point deterioration is defined as the time from the date of randomization to the date of event, which is defined as at least 10 points absolute increase from baseline (worsening) of the corresponding scale score, with no later change below the threshold or death due to any cause

  11. Change from baseline in EORTC-QLQ-C30

    Time frame: Approximately up to 33 months

    The EORTC QLQ-C30 is a questionnaire developed to assess the health-related quality of life of cancer participants. The questionnaire contains 30 items and is composed of both multi-item scales and single-item measures based on the participants experience over the past week.
