New hope for rare, aggressive cancer: drug cocktail shows promise in trial
NCT ID NCT02820857
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study tested whether adding the drug bevacizumab (Avastin) to standard chemotherapy (Folfiri) helps people with advanced, aggressive neuroendocrine carcinoma live longer after their first treatment stops working. The trial included 153 adults with inoperable cancer that started in the digestive tract or an unknown location. The main goal was to see how many patients were alive six months after starting the new treatment.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- bevacizumab (Avastin) plus Folfiri (a chemotherapy combination)
- What this could lead to
- If successful, this could provide a new second-line treatment option for patients with advanced neuroendocrine carcinoma, potentially extending survival.
- What could go wrong
- This is a Phase 2 trial with a modest sample size, so results may not be definitive. The combination may not improve survival over Folfiri alone and could cause side effects like bleeding or high blood pressure.

Inclusion Criteria: * Man or woman aged ≥ 18 years old, * Poorly differentiated neuroendocrine carcinoma (NEC) from a gastrointestinal tract (from esophagus to anal canal) and biliopancreatic primary or an unknown primary cancer, locally advanced and/or metastatic, * Centralized review of the diagnostic by a consulting pathologist specializing in NET (TENPATH network), * Recommendation of a second-line chemotherapy after progression, documented using the RECIST criteria v.1.1, and after a first-line chemotherapy treatment by cisplatin (or carboplatin) + etoposide or in the event of progression in the 6 months following the discontinuation of this first-line treatment, * Recommendation of a second-line chemotherapy for the refractory patient or contraindicated for platinum-etoposide chemotherapy * Patients presenting at least one measurable target lesion according to the RECIST criteria v.1.1, in an area not previously irradiated, * General condition ≤ 2 (WHO), * Patient of child bearing age accepting to use an effective contraception during treatment and until 6 months after the last administration, * Patient who signed the informed consent form. Exclusion Criteria: 1. Relating to the tumor, the patient, and previous treatment: * Well differentiated neuroendocrine tumor * Mixed tumor, except if the NEC component is \> 70%, the patient is eligible, * First-line chemotherapy other than cisplatin (or carboplatin) and etoposide, * All malignant disease in the three years before randomization, with the exception of basal cell carcinoma or in situ cancer treated for curative purposes, * A pregnant or breastfeeding woman, * Lack of efficient contraception (for men or women of reproductive age), * All medical, geographical, social, and psychological conditions or a legal situation that will not allow the patient to finish the study or sign an informed consent form, 2. Relating to the chemotherapy (Folfiri): * Any of the following uncontrolled progressive diseases in the 6 months before randomization: liver failure, renal insufficiency, respiratory distress, congestive heart failure (NYHA III-IV), unstable angina, myocardial infarction, significant arrhythmia, * Known deficiency in dihydropyrimidine dehydrogenase, * Known Gilbert's syndrome, * Total bilirubin level \>1.5x the upper limit of normal (ULN); AST (Aspartate transaminase) and/or ALT (Alanine transaminase) \>5x ULN; TP \<50%; * Neutrophils \<1.5x109/l, platelets \<100x109/l, hemoglobin \<9 g/dl, * Chronic uncontrolled diarrhea, unresolved intestinal occlusion or subocclusion, * History of anaphylactic reaction or known intolerance to atropine (sulfate) or to loperamide or to antiemetics administered in association with Folfiri, * All treatment with concomitant anticonvulsive agents, CYP3A4 inducers (phenytoin, phenobarbital, carbamazepine), discontinued for at least 7 days, 3. Relating to bevacizumab: * Uncontrolled brain metastases (by local treatment), * All uncontrolled progressive disease within 1 month prior to randomization: grade 3-4 gastrointestinal bleeding (peptic ulcer, erosive esophagitis or gastritis), infectious disease or intestinal inflammation, diverticulitis, pulmonary embolism or other uncontrolled thromboembolic event, * Uncontrolled high blood pressure defined as a systolic blood pressure \>140 mmHg or diastolic pressure \>90 mmHg, * Patients receiving anticoagulant treatment with an unstable dose of a vitamin K antagonist treatment, and/or having an abnormal INR (\>3) in the four weeks before the randomization, * Verified proteinuria above or equal to 1g/24 hours measured from 24 hours of urine if the urinary protein dipstick control is above or equal to 2+, * Creatinine clearance (MDRD) \<50 ml/min. * Hypersensitivity to the active substance or to any of the excipients. * Hypersensitivity to Chinese Hamster Ovary (CHO) cell products or other recombinant human or humanised antibodies.
