Comparator
None/Not specified
Adaptive
True, dose-escalation elements described: Phase I aims to assess safety/tolerability and identify recommended dose(s) (RD) and/or dose range for optimization (DRO) for further evaluation (i.e. escalation and dose-finding with expansion cohorts).
Biomarker Stratified
True, CCNE1 amplification (patients with histologically and/or cytologically confirmed locally advanced or metastatic cancer with a CCNE1 amplification are eligible in Phase I).
Single Multiple Or Escalation Dose Combined
Yes
Target Sample Size
62

Eligibility

Recruits 62 isVulnerablePopulationSelected=true. Informed consent is required via adult ICFs (multiple country-specific adult ICFs are included). A 'Parent Legal Guardian' ICF document is present in the document list (French NonRed), indicating provision for consent by a legal guardian where applicable; however the protocol inclusion criteria specify Age ≥ 18 years. No explicit assent procedures for minors are provided in the available data..

Pregnancy Exclusion
Women of child-bearing potential (WOCBP) who are unwilling to use highly effective contraception methods, pregnant or nursing women.
Vulnerable Population
isVulnerablePopulationSelected=true. Informed consent is required via adult ICFs (multiple country-specific adult ICFs are included).

Inclusion criteria

  • {"criterion_text":"- Age ≥ 18 years old.\n- Phase I - Patients with one of the following indications: HR+/HER2- aBC with disease progression on or following at least one line of hormone-based therapy in combination with a CDK4/6i and at least one additional line of systemic therapy for metastatic disease. Histologically and/or cytologically confirmed diagnosis of locally advanced or metastatic cancer with a CCNE1 amplification. For dose expansion only: no more than 3 prior lines of therapy for advanced or metastatic disease.\n- Phase II - Patients with the following indication: HR+/HER2- aBC with disease progression on an aromatase inhibitor or tamoxifen in combination with a CDK4/6 inhibitor for unresectable/metastatic disease with no more than 2 lines of endocrine therapy.\n- Measurable disease as determined by RECIST v1.1. Breast Cancer only - If no measurable disease is present, then at least one predominantly lytic bone lesion must be present that can be accurately assessed at baseline and is suitable for repeated assessment"}

Exclusion criteria

  • {"criterion_text":"- Previous treatment with a CDK2 inhibitor at any time.\n- Patients with inadequate bone marrow and/or organ functions with out-of-range laboratory values.\n- Clinically significant, uncontrolled heart disease and/or cardiac repolarization abnormality including MI, CABG, long QT syndrome, or risk factors for TdP.\n- Presence of symptomatic CNS metastases or CNS metastases that require local therapy or increasing doses of corticosteroids within 2 weeks prior to study entry.\n- For the combination treatment: Patients with symptomatic visceral disease or any disease burden that makes the patient ineligible for endocrine-based therapy. Patients who could not tolerate the prescribed dose of ribociclib during a previous course of treatment, requiring dose reduction or permanent discontinuation due to adverse events.\n- For patients with Breast Cancer: Patient is concurrently using hormone replacement therapy.\n- Women of child-bearing potential (WOCBP) who are unwilling to use highly effective contraception methods, pregnant or nursing women."}

Endpoints

Primary endpoints

  • {"endpoint_text":"- Phase I: Safety – Incidence and severity of dose-limiting toxicities (DLTs), adverse events (AEs) and serious adverse events (SAEs), including changes in lab values, vital signs, electrocardiograms (ECGs). Tolerability – Frequency of dose interruptions, reductions, discontinuations.","definition_or_measurement_approach":"Safety and tolerability assessed by incidence and severity of DLTs, AEs and SAEs, including laboratory values, vital signs and ECG changes; tolerability by frequency of dose interruptions, reductions and discontinuations."}
  • {"endpoint_text":"- Phase II: Progression Free Survival (PFS) rate 6 months per local response evaluation criteria in solid tumors (RECIST v1.1).","definition_or_measurement_approach":"PFS at 6 months determined by local assessment according to RECIST v1.1."}

Secondary endpoints

  • {"endpoint_text":"- Phase I: Plasma concentrations of ECI830, ribociclib, and derived PK parameters including area under the curve (AUC) and maximum plasma concentration (Cmax). Overall response rate (ORR), best overall response (BOR), disease control rate (DCR), clinical benefit rate (CBR) and PFS per local RECIST v1.1.","definition_or_measurement_approach":"Pharmacokinetics: plasma concentrations and derived PK parameters (AUC, Cmax). Efficacy measures: ORR, BOR, DCR, CBR, PFS assessed locally per RECIST v1.1."}
  • {"endpoint_text":"- Phase II: ORR, BOR, PFS, DCR, CBR, duration of response (DOR) as per local RECIST v1.1, and overall survival (OS). Safety - Incidence and severity of AEs, SAEs, including changes in lab values, vital signs, ECGs. Tolerability: Frequency of dose interruptions, reductions, and discontinuations. Plasma concentration of ECI830, ribociclib, and derived PK parameters including AUC and Cmax.","definition_or_measurement_approach":"Efficacy endpoints (ORR, BOR, PFS, DCR, CBR, DOR) and OS assessed locally per RECIST v1.1. Safety assessed by incidence/severity of AEs/SAEs and clinical/lab/ECG changes. PK endpoints: plasma concentrations and AUC/Cmax."}
