Nal-IRI (ONIVYDE® ) and Carboplatin in Patients With Advanced or Metastatic GEP-NET

Phase 2Enrolling By InvitationNCT05385861

National Health Research Institutes, Taiwan52 enrolled

Overview

The current study is an investigator-initiated, single-arm phase 1/2 study that enrolled patients with advanced or recurrent and/or metastatic gastroenteropancreatic poorly differentiated neuroendocrine carcinoma for the treatment of nal-IRI (ONIVYDE®) plus carboplatin as the first-line chemotherapy.

Eligible patients will be treated into two cohorts. In adaptive phase 1 cohort: Six patients will be enrolled in safety run-in cohort of dose level 0. If less than 2 patients experience dose-limiting toxicity (DLT) in dose level 0, dose level 1 will be tested. However, if more than 1 patients experience DLT in dose level 0, dose level -1 will be tested. The MTD at which no more than 1 of the 6 patients experience DLT will be determined for the phase 2 cohort. Otherwise, additional 6 patients will be tested in the dose level -1. Based on results from safety run-in cohort, PR2D will be determined. The evaluable patients in RP2D cohort will be incorporated into phase 2 cohort for final analysis. Dose in phase 1 cohort: Dose level 1= onivyde 100 mg/m2 plus carboplatin AUC=4, intravenously both on day 1, q3wk Dose level 0= onivyde 80 mg/m2 plus carboplatin AUC=4, intravenously both on day 1, q3wk Dose level -1= onivyde 60 mg/m2 plus carboplatin AUC=4, intravenously both on day 1, q3wk Carboplatin dose (mg) is calculated by the Calvert formula: AUC x (eGFR + 25). Cockcroft-Gault equation: eGFR (calculated Ccr)= \[(140-age) x weight x 0.85 (if female)\] / (72 x serum Cr). The maximum eGFR for dose calculation is 125 ml/min. The definition of DLT: Following toxicities occur during the first cycle of the combination chemotherapy with nal-IRI (ONIVYDE®) and carboplatin will be considered as DLTs. Toxicities are assessed by the Common Terminology Criteria for Adverse Events version 5.0 (CTCAE v5.0). * Grade 4 neutropenia (ANC \< 500/μL) ≥3 days' duration under primary G-CSF support * Grade 3 or higher neutropenia (ANC \< 1,000/μL) with concurrent active infection requiring IV antibiotics treatment * Grade 4 thrombocytopenia (platelet counts \< 25,000/μL) * Grade 3 thrombocytopenia (platelet counts \< 50,000/μL) associated with active bleeding that transfusion is required * Any grade 3 or higher treatment-related non-hematologic toxicity (except for anorexia/nausea, vomiting, and asthenia/fatigue) * Any adverse drug reactions lead to more than 3 weeks delay In Phase 2 Cohort Patients will be treated until disease progression, unacceptable toxicity or other condition meeting the treatment discontinuation criteria. Tumor response will be assessed according to Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST v1.1) every 6 weeks. Adverse events (AEs) will be evaluated according to the National Cancer Institute's Common Terminology Criteria for Adverse Events version 5.0 (CTCAE v5.0). Patients sign additional consent to participate in the next generation sequencing study will be required to have extra tissue samplings at the study entry. A follow-up visit is required approximately 30 days after treatment discontinuation. Overall survival status will be followed by clinic visit or by phone every 3 months until death or the maximum of 3 years, whichever occurs first.

Inclusion Criteria: 1. histologically confirmed locally advanced or metastatic gastroenteropancreatic poorly differentiated neuroendocrine carcinoma. 2. patients either are chemotherapy-naive or had received adjuvant chemotherapy \> 6 months before recurrence. 3. at least one measurable lesion according to the RECIST version 1.1.. 4. patients were aged 20 to 80 years with ECOG performance status of 0 to 1. 5. patients had a life expectancy ≥ 3 months. 6. patients had adequate renal function with defined as serum creatinine ≤ 2 times the upper limit of normal (ULN) or eGFR (calculated Ccr) ≥ 45 mL/min. 7. patients had adequate hepatic function, defined as total bilirubin ≤ 1.5 times the ULN and alanine aminotransferase ≤ 2.5 the ULN and ≤ 5 times the ULN within the setting of liver metastases. 8. patients had adequate bone marrow function, defined as an absolute neutrophil count ≥ 1500/mm3, platelet count ≥ 100,000/mm3, and hemoglobin ≥ 9 g/dL. 9. Normal ECG or abnormal ECG without any clinical significantly findings. 10. Able to understand and sign an informed consent (or have a legal representative who is able to do so). Exclusion Criteria: 1. a history of palliative chemotherapy or disease recurrence \< 6 months from the time of last adjuvant chemotherapy and/or radiotherapy. 2. known hypersensitivity to liposome product, irinotecan or carboplatin. 3. receipt of major surgery within the past 4 weeks before study enrollment. 4.
