General information about the trial
|
|||
Main objective of the trial |
To assess FOLFIRI + aflibercept efficacy in patients with or without angiotensin converting enzyme (ACE) polymorphisms in terms of progression-free survival (PFS).
|
||
Protection of trial subjects |
All patients included in the clinical trial received the combination of aflibercept + FOLFIRI regimen in 2-week cycles. Treatment was given until disease progression, unacceptable toxicity or patient withdrawal (investigator or patient decision, death, appearance of any of the exclusion criteria clinically relevant, significant non-compliance with protocol, development of a second cancer, addition of an anti-neoplastic drug other tan study drugs or pregnancy).
All patients that discontinued the study treatment were followed up every 3 months to document progression (If patients withdraw from the treatment before progression), treatment-related adverse events (AE), further cancer treatments and survival, except for those who withdrew their informed consent, were lost to follow-up or died.

Recruitment
|
|||||||
Recruitment details |
One hundred and fifteen patients were recruited, 14 of whom were considered screening failures (noncompliance with selection criteria, n=11; withdrawal of consent n=2 and not possible to evaluate RECIST criteria due to patient`s weight, n=1). Therefore, 101 patients were finally included in this national study conducted in 15 Spanish hospitals. | ||||||
Pre-assignment
|
|||||||
Screening details |
Patients aged ≥18 years, with histologically proven colorectal adenocarcinoma, metastatic disease and ≥1 measurable unidimensional lesion using CT or MRI according to RECIST criteria. The mCRC had to be resistant to or progressive on an oxaliplatin-containing regimen. WHO performance status 0-2 and adequate bone marrow, renal and liver functions. | ||||||
