Colon Cancer Clinical Trial

A Safety, Pharmacokinetic and Efficacy Study of NUC-3373 in Combination With Standard Agents Used in Colorectal Cancer Treatment

Summary

This is a three-part study of NUC-3373 administered by intravenous (IV) infusion across two administration schedules, either as monotherapy or as part of various combinations with agents commonly used to treat CRC (leucovorin, oxaliplatin, irinotecan, bevacizumab, cetuximab and panitumumab). The primary objective is to identify a recommended dose and schedule for NUC-3373 when combined with these agents.

Age ≥18 years
Life expectancy of ≥12 weeks
ECOG Performance status 0 or 1
Measurable disease as defined by RECIST v1.1
Known RAS and BRAF status. Patients with wild-type KRAS tumours who are to be enrolled to a cohort that does not contain an EGFR pathway inhibitor (Arms 2a, 2b, 2c, 2d, 3a, 3b, 3c, 3d and 3e) must have received prior treatment with an EGFR inhibitor, unless this was not standard of care according to relevant region-specific treatment recommendations. Patients with BRAF V600E mutant tumours should have received prior treatment with encorafenib in combination with an EGFR inhibitor, unless this was not standard of care according to relevant region-specific treatment recommendations
Adequate bone marrow function as defined by: ANC ≥1.5×10^9/L, platelet count ≥100×10^9/L (with no evidence of bleeding), and haemoglobin ≥9 g/dL
Adequate liver function as defined by serum total bilirubin ≤1.5×ULN, AST and ALT ≤2.5×ULN (or ≤5×ULN if liver metastases present)
Adequate renal function assessed as serum creatinine <1.5×ULN or glomerular filtration rate ≥50 mL/min. This criterion does not apply to Arm 1d.
Serum albumin ≥3 g/dL
For the cohort in which the patient will participate, there are no contra-indications to receiving the approved partner combination drugs
Ability to comply with protocol requirements
Female patients of child-bearing potential must have a negative serum pregnancy test within 7 days prior to the first study drug administration. This criterion does not apply to patients who have had a previous hysterectomy or bilateral oophorectomy. Male patients and female patients of child-bearing potential must agree to practice true abstinence or to use two highly effective forms of contraception, one of which must be a barrier method.
Patients must have been advised to take measures to avoid or minimise exposure to UV light for the duration of study participation and for a period of 4 weeks following the last dose of study medication
Male patients receiving oxaliplatin must have been offered advice on and/or sought counselling for conservation of sperm prior to the first dose of study medication

>3rd-line patients

Received at least two prior lines of therapy for locally advanced or metastatic CRC, including one fluoropyrimidine plus oxaliplatin and one fluoropyrimidine plus irinotecan containing regimen. Previous treatment with SoC regimens in combination with molecular targeted therapies is permitted and patients who received FOLFOXIRI-based regimens in 1st-/2nd-line settings may be included.
Patients due to receive NUFOX should be suitable for re-challenge with an oxaliplatin-based regimen
Patients due to receive NUFIRI should be suitable for re-challenge with an irinotecan-based therapy

2nd-/3rd-line patients

Received at least one but no more than two prior lines of fluoropyrimide-containing therapy in combination with oxaliplatin and/or irinotecan for locally advanced or metastatic CRC. Previous treatment with SoC regimens in combination with molecular targeted therapies is permitted and patients who received FOLFOXIRI-based regimens in 1st-/2nd-line settings may be included. 3rd-line patients enrolled to Arms 2c and 2d must have received prior bevacizumab treatment, unless ineligible or unless bevacizumab was not standard of care according to relevant region-specific treatment recommendations
Patients in Part 2 due to receive NUFOX should be suitable for re-challenge with an oxaliplatin-based regimen
Patients in Part 2 due to receive NUFIRI should be suitable for re-challenge with an irinotecan-based regimen

Combination chemotherapy ineligible patients

May have received one prior fluoropyrimidine-containing regimen for locally advanced or metastatic CRC
Ineligible to receive combination therapy for locally advanced or metastatic CRC
Creatinine clearance >30mL/min

Rapid progressors

Received no more than two prior lines of fluoropyrimidine-containing therapy in combination with oxaliplatin and/or irinotecan for locally advanced or metastatic CRC. Previous treatment with SoC regimens in combination with molecular targeted therapies is permitted and patients who received FOLFOXIRI-based regimens in 1st-/2nd-line settings may be included.
Have had tumour progression ≤3 months of starting the last fluoropyrimide-containing regimen
Patients due to receive NUFOX should be suitable for re-challenge with an oxaliplatin-based regimen
Patients due to receive NUFIRI should be suitable for re-challenge with an irinotecan-based regimen
