Combining Curcumin With FOLFOX Chemotherapy in Patients With Inoperable Colorectal Cancer (CUFOX)

January 29, 2020 updated by: University of Leicester

A Phase I/IIa Study Combining Curcumin (Curcumin C3-Complex, Sabinsa) With Standard Care FOLFOX Chemotherapy in Patients With Inoperable Colorectal Cancer.

Oral curcumin (complex C3, Sabinsa Corp, Utah) will be given to patients with inoperable colorectal metastases who will be commencing standard care oxaliplatin-based (FOLFOX) chemotherapy for up to 12 cycles(approximately 6 months) of treatment.

Primary measurements focus on safety and tolerability. These will be recorded in real-time and report the number and severity of adverse events.

Secondary measurements will include efficacy, (measured by response rate with RECIST and overall survival in months) supported by biomarker analysis.

Detailed Description

Hypothesis Combination of oral curcumin with FOLFOX-based chemotherapy will be a safe and tolerated regimen for long-term administration to patients with colorectal metastases.

Primary objectives

To establish a tolerated dose of daily oral curcumin to be taken long-term with FOLFOX-based chemotherapy in patients with metastatic colorectal cancer will be conducted to assess:

1. Safety, tolerability and feasibility of administering oral curcumin at increasing doses escalating to 4 capsules (≈2 g C3-complex) during FOLFOX-based chemotherapy and continued for the duration of the chemotherapy course.

Secondary objectives

  1. To observe any changes to the neuropathic side-effects of chemotherapy.
  2. To observe potential for efficacy in terms of disease response and survival.
  3. To identify putative biomarkers in plasma.

This is a phase I/IIa study:

Phase I will be a traditional escalation response design study (or 3+3+3) to firstly assess the safety of this combination and identify a maximum tolerated dose up to 4 g per day.

Phase IIa will be a randomised control study comparing curcumin and FOLFOX with FOLFOX alone, recruited at a 2:1 ratio respectively.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Completion of dose escalation over 2 cycles of therapy
Time Frame: 1 year
Patients will start curcumin a week prior to chemotherapy. Upon completion of two cycles of therapy without dose-limiting toxicity in 3 consecutive patients, the dose will be escalated for the next 3 patients. Real-time adverse event reporting will be undertaken to record number and severity of events.
1 year

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Completion of (or withdrawal from) chemotherapy
Time Frame: Up to 6 months
Compliance in the study will be measured in months/cycles of therapy tolerated. Reasons for withdrawal or cessation will be documented which will include mortality, adverse events and patient reported outcomes of tolerance to the protocol regimen.
Up to 6 months
Efficacy in terms of disease response and survival
Time Frame: Up to 7 years
Response rate will be measured using RECIST. Overall survival will be measured in months.
Up to 7 years
