About
The primary objective of the study is:
• to assess the safety and tolerability of multiple oral (twice daily [BID]) doses of TRK-750 in oxaliplatin-treated colorectal cancer patients with chemotherapy-induced peripheral neuropathy (CIPN).
The secondary objectives of the study are:
The exploratory objective of this study is:
• to assess the efficacy of multiple oral (BID) doses of TRK-750 on pharmacodynamic (PD) biomarker(s) in blood, psychophysical, electrophysiological, and histological parameters of neuropathy in oxaliplatin-treated colorectal cancer patients with CIPN.

Inclusion criteria
Male or female patient between 18 and 80 years of age, inclusive.
Oxaliplatin-containing chemotherapy treatment for colorectal cancer in the adjuvant setting must have been completed ≥ 3 months, but not more than 3 years, prior to Screening.
A diagnosis of CIPN based on the following criteria:
Neuropathy of ≥ Grade 2 using the general guideline of grading scales defined in CTCAE (v5.0)
Pain or neuropathic symptoms of CIPN for a duration of ≥ 3 months, for which the patient wants intervention.
Body mass index (BMI) between 18.0 and 32.0 kg/m2, inclusive.
Females of childbearing potential will agree to use highly effective contraception (Appendix 4) from the time of signing the ICF until 90 days after the Follow-up visit. Males who are sexually active with female partners of childbearing potential will agree to use a male condom with spermicide from Day 1 until 90 days after the Follow-up visit.
Be either CIPN pain-treatment naïve or have important side effects or inadequate relief from their current CIPN pain medication (stable over last month).
Has not used non-pharmacological therapy for the treatment of any pain condition (e.g., chiropractic therapies, alternative medicine therapies, or acupuncture) for at least 2 weeks prior to start of the baseline days (Days -14 to -1), and a willingness to refrain from using these therapies throughout the study. The use of physical activity or other short-acting, symptomatic non-pharmacological therapy is permitted provided the patient is willing to maintain the same regimen or usage pattern consistently throughout the study.
Able to comprehend and willing to sign an Informed Consent Form (ICF) and to abide by the study restrictions.
Patients have a life expectancy of at least 12 months.
An EORTC QLQ-CIPN20 score of ≥ 25 based on an average of 2 assessments during the Screening period and Day 1 prior to randomisation.
At least one of the following:
Exclusion criteria
Evidence of significant uncontrolled concomitant disease that could affect compliance with the protocol, ability to complete the study, and study assessments.
Presence of skin conditions in the affected dermatome that, in the judgement of the Investigator, could interfere with evaluation of the neuropathic pain condition.
Presence of non-CIPN pain that may interfere with study assessments and/or self-evaluation of peripheral neuropathic pain.
Known history of significant hypersensitivity, intolerance, or allergy.
Peripheral neuropathy caused by tumour infiltration or compression of spinal nerves or surgical trauma.
Active clinically significant infection
Unstable cardiac disease or myocardial infarction within 6 months prior to study entry.
Patients with uncontrolled major psychiatric disorders, such as major depression or psychosis.
History of pre-existing symptomatic neuropathy prior to chemotherapy, including neuropathy due to alcoholism, vitamin B deficiency, diabetes, hypothyroidism, human immunodeficiency virus (HIV), congenital neuropathy, and toxic neuropathy.
Female patients who are pregnant (including a positive urine pregnancy test at Screening or on Day 1) or lactating.
Inadequate haematological function, defined as neutrophil count < 1.0 × 10^9/L and platelet count < 50 × 10^9/L with measured values of these in the clinical laboratory tests conducted at Screening. At Screening, haematology assessments may be repeated once.
Inadequate renal function, defined as estimated glomerular filtration rate (eGFR) ≤ 59 mL/min, i.e., Creatinine Clearance (CrCl) as calculated using the Cockcroft-Gault equation with measured values of these in the clinical laboratory tests conducted at Screening:
At Screening, clinical laboratory assessments may be repeated once.
History of alcoholism or drug/chemical abuse within 1 year prior to Day 1.
Positive test results for drugs of abuse at Screening (confirmed by repeat) or Day 1, unless consistent with use of prescription medication and approved by the Sponsor (or delegate). A repeated positive test result for cocaine, phencyclidine, methadone, or amphetamines, for nonmedical use, are unconditionally exclusionary.
Positive test for hepatitis B surface antigen (HbsAg), hepatitis C antibody (HCV), or HIV antibody at Screening.
Use of any medication in the absence of appropriate washout periods that, in the opinion of the Investigator, may influence the result of the study, or the patient's ability to participate in the study.
Has received an investigational product or has been treated with an investigational device within 90 days prior to first drug administration and will not start any other investigational product or device study within 90 days after last study drug administration.
Likely to require chemotherapy during the study period or any other treatment that may interfere with compliance with the protocol, ability to complete the study, and study assessments.
Plans to change current medications or any other intervention intended to treat or relieve CIPN signs or symptoms from Screening to end of study.
Has previously received TRK-750.
