A Phase I/IB Trial of MEK162 in Combination With Erlotinib in NSCLC Harboring KRAS or EGFR Mutation

• Status: Active, not recruiting
• Trial end date: 2023-04-30
• Target enrollment: 0
• Participant gender: All

Summary

The main purpose of this study is to find out if the drugs MEK162 and erlotinib (Tarceva) given in combination are safe and have beneficial effects in patients who have NSCLC.

The U.S. Food and Drug Administration (FDA) has not approved MEK162 for use to treat NSCLC. Erlotinib is an FDA approved drug for the treatment of Non-Small Cell Lung Cancer.

• Phase: Phase 1
• Accepts Healthy Volunteers?: No

Details

• Lead Sponsor: H. Lee Moffitt Cancer Center and Research Institute
• Collaborator: Array BioPharma
• Treatments: Erlotinib Hydrochloride; Mitogens

Criteria

Inclusion Criteria:

• Eligible patients will have a histologic or cytologic diagnosis of NSCLC of the advanced stage (IV), with no known curative treatment options.

• Have a tissue or blood proven KRAS or EGFR mutation confirmed in a Clinical Laboratory Improvement Amendments (CLIA)certified lab (only required in the Phase IB expansion cohort).

• For Phase I/Ib enrollment, Patients with a CLIA confirmed EGFR mutation may be treatment naïve. All other patients must have received at least one previous line of therapy. There will be no limits to prior lines of treatment for the Phase 1 portion.

• Eastern Cooperative Oncology Group (ECOG) performance status of either 0 or 1

• There will be no limits to prior lines of treatment.

• At least one measurable site of disease (as defined by Response Evaluation Criteria in Solid Tumors), or other disease specific response assessment criteria, as appropriate (RECIST 1.1).

• Have discontinued all previous systemic therapies and recovered from side effects due to systemic treatment for more than 14 days prior to starting on treatment.

• Have discontinued all previous biologic therapies and recovered from side effects due to biologic treatment for more than 14 days prior to starting on treatment.

• Have discontinued all previous external beam radiation therapy and recovered from side effects due to radiation therapy for more than 14 days prior to starting on treatment.

• Have archival tissue sample (if available) or be willing to undergo a repeat biopsy (if feasible).

• Negative serum pregnancy test within 72 hours prior to the first study dose in all women of childbearing potential (WOCBP).

• Adequate organ function and lab parameters

• Prior to any screening or invasive procedure, written informed consent must be obtained.

Exclusion Criteria:

• Does not have adequate cardiac function

• Patients with documented central nervous system or leptomeningeal metastasis (brain metastasis) at time of study entry. Patients with prior brain metastasis may be considered if they have completed their treatment for brain metastasis, no longer require corticosteroids, and are asymptomatic.

• Any other serious uncontrolled medical disorder or active infection that would impair the patient's ability to receive study treatment

• Prior use of MEK162 or concurrent use of other approved anticancer or investigational agents. Patients treated with prior EGFR TKI therapy (including erlotinib) are allowed to enroll.

• Gastrointestinal disease that precludes absorption

• History or current evidence of central serous retinopathy (CSR) or retinal vein occlusion (RVO)

• Any ophthalmopathy visible at screening that would be considered a risk factor for CSR or RVO by the ophthalmologist

• History of another malignancy within 2 years, except cured basal cell carcinoma of the skin or excised carcinoma in situ of the cervix

• Patients who have received prior anti-cancer treatment within the following time frames: systemic therapies less than 14 days prior to starting on treatment; radiation therapy less than 14 days prior to starting on treatment; biologic therapy less than 14 days prior to starting on treatment.

• Patients who have not recovered from side effects of prior anti-cancer treatment to less than or equal to grade 1 toxicity according to Common Toxicity Criteria for Adverse Effects (CTCAE) v.4 within the following time frames: Received previous systemic therapy and has not recovered from side effects for more than 14 days prior to starting on treatment; Received previous radiation therapy and has not recovered from side effects for more than 14 days prior to starting on treatment; Received previous biologic therapy and has not recovered from side effects for more than 14 days prior to starting on treatment

• Have undergone major surgery < 4 weeks of initiation of study medication or who have not recovered from side effects of such procedure

• Patients with concurrent uncontrolled medical conditions that may interfere with their participation in the study or potentially affect the interpretation of the study data

• Women who are pregnant or nursing

• Women of child-bearing potential (WOCBP) and males who have not been sterilized by vasectomy or other means with partners who are WOCBP, UNLESS the women are using two birth control methods. The two methods can be a double barrier method or a barrier method plus a hormonal method.

• Unwilling or unable to comply with the protocol

• Known positive serology for HIV, active Hepatitis B, and/or active Hepatitis C infection

• History of Gilbert's syndrome

• Neuromuscular disorders that are associated with elevated creatinine kinase (CK)

• Patients who are planning on embarking on a new strenuous exercise regimen after first dose of study treatment. Muscular activities, such as strenuous exercise, that can result in significant increases in plasma CK levels should be avoided while on MEK162 treatment.

• Previous treatment with any substrate of CYP2B6 enzyme < 14 days prior to initiation of investigational products
