Study summary

The study purpose is to evaluate the safety, tolerability, and preliminary efficacy of the addition of INC280, trametinib, ribociclib, gefitinib, or LXH254 to EGF816 in adult patients with advanced Epidermal growth factor receptor- mutant (EGFR-mutant) non-small cell lung cancer (NSCLC).

Read the detailed description

This is a Phase Ib, open label, non-randomized dose escalation study of EGF816 in combination with ribociclib, trametinib, or LXH254, followed by dose expansion of EGF816 in combination with ribociclib, trametinib, LXH254, INC280, or gefitinib in adult patients with advanced EGFR-mutant NSCLC.

During the dose escalation part, patients were assigned to the addition of trametinib, ribociclib, or LXH254 to EGF816.

Following determination of the recommended dose for the combination of EGF816 + trametinib, EGF816 + ribociclib, and EGF816 + LXH254, patients could be enrolled to the dose expansion arms of each of these combinations. Patients could also be assigned to EGF816 + INC280. The planned arm EGF816 + gefitinib in dose expansion was not opened for enrollment.

Inclusion criteria

  • Patients must have or cytologically confirmed locally advanced (stage IIIB) or (stage IV) EGFR mutant (ex19del, L858R) NSCLC.
  • Requirements of EGFR mutation status and :
  • Treatment naive patients, who have locally advanced or metastatic NSCLC with EGFR sensitizing mutation (e.g., L858R and/or ex19del), have not received any systemic antineoplastic therapy for advanced NSCLC and are eligible to receive EGFR TKI treatment. Patients with EGFR exon 20 insertion/duplication are not eligible. Note: patients who have received only one cycle of chemotherapy in the advanced setting are allowed.
  • Patients who have locally advanced or metastatic NSCLC with EGFR sensitizing mutation AND an acquired T790M mutation (e.g., L858R and/or ex19del, T790M+) following progression on prior treatment with a 1st-generation EGFR TKI or 2nd-generation EGFR TKI. These patients may not have received more than 4 prior lines of antineoplastic therapy in the advanced setting, including EGFR TKI, and may not have received any agent targeting EGFR T790M mutation (i.e., 3rd-generation EGFR TKI).
  • Patients who have locally advanced or metastatic NSCLC with EGFR sensitizing mutation and a "de novo" T790M mutation (i.e., no prior treatment with any agent known to inhibit EGFR including EGFR TKI). These patients may not have received more than 3 prior lines of antineoplastic therapy in the advanced setting, and may not have received any prior 3rd generation EGFR TKI.
  • Patients must have a site of disease amenable to , and be a candidate for tumor biopsy according to the treating institution's guidelines. Patients must be willing to undergo a new tumor biopsy during therapy on this study, and at screening if an archival tumor sample obtained since the diagnosis of advanced disease (1L patients) or since last treatment failure (2L+ patients) is not available.

Exclusion criteria

Exclusion Criteria:

  • Patients with a history or presence of interstitial lung disease or interstitial pneumonitis, including radiation pneumonitis.
  • Patients with unstable .
  • Patients with a history of another .
  • Patients with a known history of (HIV) seropositivity.
  • Patients with clinically significant, uncontrolled heart disease.
  • Patients participating in additional parallel drug or medical device studies.
  • Prior therapies:
  • Patients who have been treated with EGFR TKI in the setting within 6 months, unless acquired EGFR T790M is present in a tumor or blood sample obtained since the discontinuation of the EGFR TKI.
  • Patients who have been treated with prior EGFR TKI targeting T790M (3rd generation).
  • Patients who have been treated with systemic anti-neoplastic therapy within:

    • 2 weeks for fluoropyrimidine monotherapy
    • 6 weeks for nitrosoureas and mitomycin
    • 4 weeks or ≤ 5 half-lives (whichever is shorter) for biological therapy (including monoclonal antibodies) and continuous or intermittent small molecule therapeutics or any other investigational agent
Terms in these criteria, in plain language(10)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Histologically or cytologically confirmed

The diagnosis was confirmed by looking at a sample under a microscope: tissue from a biopsy or surgery (histology), or cells from a fluid or needle sample (cytology).

Your pathology report is the document that shows this.

Metastases

Cancer that has spread from where it began to other parts of the body. “Metastatic” cancer is cancer that has spread this way.

Line of therapy

A line of therapy is one course of treatment, which may combine several drugs. First-line is the first course given; second-line follows when that stops working or is not tolerated.

“Two prior lines” means two courses that count separately under the study’s rules — not simply two drugs. Ask the study team if you are unsure how yours are counted.

Biopsy and archival tissue

A biopsy takes a small piece of tissue to examine. “Archival tissue” is a sample already taken, for example at diagnosis, and kept by the hospital.

Whether a stored sample will do depends on when it was taken, how much there is and what the study needs. Ask whether the study accepts your stored sample or needs a new biopsy.

Clinically significant

Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.

Brain metastases

Cancer deposits in the brain from a cancer that started elsewhere in the body (CNS metastases include the spinal cord).

Studies differ: some leave out any brain metastases, some accept ones treated and stable for some weeks. Check what this study allows.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

HIV

The human immunodeficiency virus, which weakens the immune system.

Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

Adjuvant and neoadjuvant

Neoadjuvant treatment is given before the main treatment (usually surgery), often to shrink a tumour. Adjuvant treatment is given after it, to lower the chance of the cancer coming back.

What researchers measure

Primary outcomes

  1. Number of patients with adverse events and serious adverse events

    Assess safety and tolerability including incidence of dose limiting toxicities, adverse events, and serious adverse events.

    Time frame: Every day until study end, approximately 4 years

  2. Number of participants with DLTs in the first cycle of combination (Dose escalation only)

    A Dose-Limiting Toxicity (DLT) is defined as an adverse event or abnormal laboratory value of Common Terminology Criteria for Adverse Events (CTCAE) grade ≥ 3 assessed as unrelated to disease, disease progression, inter-current illness or concomitant medications that occurs within the first 28 days of combination treatment during the dose escalation part of the study. Other clinically significant toxicities may be considered to be DLTs, even if not CTCAE grade 3 or higher.

    Time frame: 28 days

  3. Number of participants with dose interruptions and reductions

    Assessment of tolerability. For patients who do not tolerate the protocol-specified dosing schedule, dose adjustments may be permitted in order to allow patients to continue the study treatment.

    Time frame: From first dose until study ends, approximately 4 years

  4. Dose intensity of study drugs

    Dose intensity is computed as the ratio of actual cumulative dose received to actual duration of exposure.

    Time frame: From first dose until study ends, approximately 4 years

  5. ORR2

    Modified objective response rate (ORR2) per RECIST v1.1 (taking as baseline the most recent assessment prior to initiating combination)

    Time frame: Every 8-12 weeks until study ends, approximately 4 years

Secondary outcomes

  1. ORR

    Overall response rate (ORR) per RECIST v1.1

    Time frame: Every 8-12 weeks until study ends, approximately 4 years

  2. PFS

    Time from the date of first dose of study treatment to the date of first documented disease progression (per RECIST v1.1) or death due to any cause

    Time frame: Every 8-12 weeks until study ends, approximately 4 years

  3. DCR

    Proportion of patients with best overall response of CR, PR, or SD

    Time frame: Every 8-12 weeks until study ends, approximately 4 years

  4. DOR

    Time from first documented response (PR or CR) to the date of first documented disease progression or death due to any cause

    Time frame: Every 8-12 weeks until study ends, approximately 4 years

  5. Time to response

    Time to response is the time between start of treatment until first documented response per RECIST v1.1.

    Time frame: Every 8-12 weeks until study ends, approximately 4 years

  6. Area under the plasma concentration-time curve (AUC) of study drugs

    Pharmacokinetic (PK) parameters calculated based on the plasma concentrations versus time profiles by using non-compartmental methods.

    Time frame: From pre-dose up to 8 hours post-dose on Day 15 of Cycle 1. One cycle=28 days.

  7. Maximum observed plasma concentration (Cmax) of study drugs

    PK parameters calculated based on the plasma concentrations versus time profiles by using non-compartmental methods.

    Time frame: From pre-dose up to 8 hours post-dose on Day 15 of Cycle 1. One cycle=28 days.

Started Jan 2018 (actual). Primary completion is estimated for Jul 2027, 113 months after the start.

Of 473 industry-sponsored phase 1 interventional studies under Carcinoma, Non-Small-Cell Lung, half reached primary completion within 49 months of starting (the median), counting those still running; a quarter within 29 and three quarters within 66. This study's planned 113 months is above that.

Counting every sponsor, half of 699 studies reached it within 50 months; a quarter within 31 and three quarters within 70.

Since we started tracking on Sep 25, 2026, the dates moved once, on Nov 5, 2026: primary completion Oct 2026 → Jul 2027 and completion Oct 2026 → Jul 2027.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
