About

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).

Full 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.

Enrollment: 105 patients

Sex: All

Ages: 18 to 100 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• Patients must have histologically or cytologically confirmed locally advanced (stage IIIB) or metastatic (stage IV) EGFR mutant (ex19del, L858R) NSCLC.
• Requirements of EGFR mutation status and prior lines of treatment:
• 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 biopsy, 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

• Patients with a history or presence of interstitial lung disease or interstitial pneumonitis, including clinically significant radiation pneumonitis.

• Patients with unstable brain metastases.

• Patients with a history of another malignancy.

• Patients with a known history of human immunodeficiency virus (HIV) seropositivity.

• Patients with clinically significant, uncontrolled heart disease.

• Patients participating in additional parallel investigational drug or medical device studies.

• Prior therapies:

• Patients who have been treated with EGFR TKI in the adjuvant 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
