Foxy-5 FOLFOX regimen [leucovorin (43530), fluorouracil (32268), oxaliplatin (103030)] ...Study Participants
100Phase II study investigating the safety, tolerability and effect on disease reccurence of Foxy-5 as neo-adjuvant therapy in resected colon cancer patients treated with FOLFOX chemotherapy regimen. It is a two-arm study and patients will be randomised to receive either standard therapy (surgery + FOLFOX 6 months regimen) or standard therapy + neo-adjuvant administration of Foxy-5 prior to- and following surgery (maximum of 39 administrations) until initiation of FOLFOX therapy.
Foxy-5 is a synthetic hexapeptide with a formylated N-terminus, derived from the protein sequence of the Wnt-5a protein. Low/no expression levels of Wnt-5 protein in primary tumour cells have been correlated to high risk of recurrent metastatic disease and shortened survival in several different types of cancer patients, including colon cancer.
Current standard therapy involves surgical removal of the tumour followed by 6 months treatment with chemotherapy (FOLFOX). Foxy-5 is expected to decrease migration of cancer cells, in subjects with low/absent levels of Wnt-5a protein in their primary tumour and hence result in lower recurrence and a better overall survival. The trial intends to establish the safety and tolerability of Foxy-5 and to evaluate early signs of anti-metastatic activity in subjects with resectable colon cancer.

Inclusion Criteria: Ability to understand and willingness to provide written informed consent before any trial-related activities. 18 years of age or older. Male or female subjects with adenocarcinoma of the colon, judged by CT or MRI as either one of the following stages per TNM classification of colon cancer (8th edition, 2017): T1-4, N1-2, M0 or T4, N0, M0 and who are considered to fulfil the local criteria for adjuvant post- operative chemotherapy after scheduled surgery. Scheduling of surgery according to local practice allows at least 9 pre- surgery administrations of Foxy-5 for the subject. (Please note: surgery should not be postponed for trial purposes.) Sexually active women of childbearing potential (WOCBP) and males with WOCBP partners who are randomized to the Foxy-5 Arm must use a highly effective method of contraception for the treatment duration and for 28 days after last Foxy-5. Eastern Cooperative Oncology Group (ECOG) performance status of 0-1. Clinical laboratory values at screening: Absolute neutrophil count ≥1.5 x 109/L Haemoglobin ≥ 9 g/dL Platelets ≥ 100 x 109/L Aspartate Transaminase (AST) and Alanine Transaminase (ALT) ≤1.5x Upper Limit of Normal (ULN) Serum bilirubin ≤1.5 x the ULN Creatinine clearance >60 mL/min (determined by Cockcroft-Gault Equation). Exclusion Criteria: Assessed as not suitable or unable to tolerate adjuvant chemotherapy. Evidence of distant metastatic (M1) disease at Screening (N1-2 is allowed). Any surgery (except tumour biopsy) or therapy with immune suppressive agents or bone marrow stimulating factors within the last two weeks prior to randomization. Any active infection requiring IV antibiotic treatment at the time of screening. History of hematologic or primary solid tumour malignancy. Pregnant or breastfeeding women. Currently participating in another trial and receiving trial therapy or received investigational therapy within 4 weeks of the first dose of Foxy-5. Any other condition or treatment that, in the opinion of the Investigator, might interfere with the trial or current drug or substance abuse. Inability to understand the protocol requirements, instructions and trial-related restrictions, the nature, scope, and possible consequences of the trial. Unlikely to comply with the protocol requirements, instructions and trial-related restrictions; e.g., uncooperative attitude, inability to return for follow-up visits, and improbability of completing the trial. Legal incapacity or limited legal capacity. Any condition, which results in an undue risk for the subject during the trial participation according to the Investigator.
