Overview
Brief Summary
This is a Phase I, open-label, multi-center, dose-finding study to assess the safety, pharmacokinetics, and preliminary efficacy of ET0038 in patients with advanced solid tumors. It is anticipated that approximately 34 subjects will be enrolled in the dose-escalation phase of the study. ET0038 will be administered orally once daily (QD) in 21-day treatment cycles.
Detailed Description
This is an open-label, multicenter, Phase 1 study of oral ET0038 monotherapy in participants with advanced solid tumors. The study will include 2 components: 1) a Dose-Escalation Component for participants with advanced solid tumors and 2) a Dose-Expansion Component for participants with advanced solid tumors harboring certain specific mutations/rearrangements that result in hyperactivation of the RAS-MAPK pathway. Participants will be treated until disease progression per RECIST v1.1, unacceptable toxicity, or other criteria for withdrawal are met, whichever occurs first.
Investigators
Eligibility Criteria
Inclusion Criteria
- •Provision of signed and dated, written informed consent prior to any study specific procedures, sampling and analyses.
- •Aged at least 18 years at the time of ICF signature.
- •Histological or cytological confirmation of a solid tumor and have progressed despite standard therapy(ies), or are intolerant to standard therapy (ies), or have a tumor for which no standard therapy(ies) exists. Locally recurrent disease must not be amenable to surgical resection or radiotherapy with curative intent (patients who are considered suitable for surgical or ablative techniques following down-staging with study treatment are not eligible).
- •Estimated life expectancy of minimum of 12 weeks.
- •Patient with solid tumors must have at least 1 lesion, not previously irradiated, that can be accurately measured at pre-dose as ≥ 10 mm in the longest diameter (except lymph nodes which must have short axis ≥ 15 mm) with Computerised Tomography (CT) or magnetic resonance imaging (MRI) and which is suitable for accurate repeated measurements.
- •Eastern Cooperative Oncology Group (ECOG) performance status 0 or 1 at ICF signature.
- •Males and Females of child-bearing potential must agree to use effective contraception from the time ICF signature until 12 weeks after the last dose. Females of childbearing potential include those who are premenopausal and those who are 2 years postmenopausal. Pregnancy tests for female of child-bearing potential must have a negative serum pregnancy test at Screening.
Exclusion Criteria
- •Primary central nervous system (CNS) tumor or uncontrolled CNS metastasis (severe clinical symptoms, bleeding, disease progression or steroid hormone use within 14 days before enrollment)..
- •As judged by the investigator, any evidence of significant ophthalmological abnormalities including but not limited to history or current evidence of retinal vein occlusion (RVO) or current risk factors for RVO, retinal macular degeneration, uncontrolled glaucoma, cataract or marked decrease in visual acuity, symptomatic severe dry eye, conjunctivitis, or corneal ulcer.
- •Prior bone marrow or organ transplantation
- •Prior treatment with ET0038 or a SHP2 inhibitor.
- •Prior therapy with any investigational drugs or systemic anticancer treatment within 28 days (or a period of 5 'half-lives' of this investigational drugs or systemic anticancer treatment, whichever is the most appropriate and as judged by the investigator) at the time of ICF signature.
- •Radiotherapy with a wide field of radiation within 28 days, or radiotherapy with a limited field of radiation for palliation within 14 days at the time of ICF signature, or planning radical radiation therapy while participating in the study.
- •Prior major surgery (excluding placement of vascular access) within 28 days at the time of ICF signature, or planning for major surgery while participating in the study.
- •With the exception of alopecia, any unresolved toxicities from prior therapy greater than Common Terminology Criteria for Adverse Events (CTCAE5.0) Grade 1 at the time of ICF signature.
- •Any uncontrolled active infection requiring parenteral administration of antibiotics, antivirals, or antifungals at the time of ICF signature and/or within one week of Cycle 1 Day 1 (C1D1).
- •Patient with a history of active pulmonary tuberculosis infection within 1 year prior to screening (as judged by investigator, active pulmonary tuberculosis infection more than 1 year and no evidence of active pulmonary tuberculosis at present will be considering eligible)
Arms & Interventions
Dose Escalation
Oral capsules taken in escalating levels to determine MTD/RP2D. Each treatment cycle will be 21 days in duration with ET0038 administered, once daily (QD).
Intervention: ET0038
Outcomes
Primary Outcomes
Recommended Phase 2 Dose (RP2D)
Time Frame: Approximately 2 years
RP2D may be the same dose level or lower than the determined MTD.
Determination of Maximum Tolerated Dose (MTD) of ET0038
Time Frame: Approximately 2 years
MTD based on Number of participants with dose limiting toxicities (DLTs) in the dose escalation phase. A DLT is defined as any toxicity not attributable to the disease or disease-related processes under investigation, which occurs before the end of Cycle 1 (21 days as a cycle)
Number of participants with adverse events
Time Frame: Approximately 2 years
All patients participating in this study will be assessed for incidence and severity of adverse events (AEs) and serious AEs, including changes in laboratory values, vital signs, electrocardiograms, cardiac imaging and ophthalmological assessments
Secondary Outcomes
- Tmax(Approximately 2 years)
- Area under the curve(Approximately 2 years)
- Cmax(Approximately 2 years)
- T1/2(Approximately 2 years)
- Objective response rate(Approximately 2 years)
