NIAGEN and Persistent Chemotherapy-Induced Peripheral Neuropathy

Running, not enrolling · Phase 2 · Has a placebo group

Conditions studied: Chemotherapy-induced Peripheral Neuropathy

In brief

The purpose of this randomized, double-blind, placebo-controlled, parallel group phase II trial is to determine whether nicotinamide riboside (NIAGEN®, NR) can ameliorate persistent peripheral neuropathy in cancer survivors who have completed chemotherapy with taxane or platinum-complex compounds between 1 and 12 months earlier.

Who can join

Age: 18 and older, up to 85. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Be able to give written informed consent and HIPAA authorization
• Be ≥ 18 and ≤ 85 years of age
• Have received chemotherapy with taxane (e.g. paclitaxel, nab-paclitaxel, or docetaxol) or platinum-complex (e.g. oxaliplatin, carboplatin, or cisplatin) (alone or in combination) and completed therapy no sooner than 1 month and no later than 1 year earlier.
• Have been treated with above compounds for head and neck cancer, small cell lung cancer, sarcoma, ovarian cancer, endometrial cancer, colorectal cancer, or breast cancer and been declared to have no visible evidence of disease.
• Have an Eastern Cooperative Oncology Group (ECOG) Performance Status of 0-2
• Able to take medication orally - up to four capsules in the morning (am) and four capsules in the evening (pm).
• Be determined to have a raw score of ≥ 12 on the sensory subscale or ≥ 11 on the motor subscale of the QLQ-CIPN20 questionnaire.
• Females must be either postmenopausal for at least 1 year or surgically sterile for at least 6 weeks. Females of childbearing potential must have a negative pregnancy test at screening to be eligible for study participation and agree to take appropriate precautions to avoid pregnancy from screening through follow-up.
• Males must agree to take appropriate precautions to avoid fathering a child from screening through follow-up. The following methods have been determined to be more than 99% effective (<1% failure rate per year when used consistently and correctly) [69] and are permitted under this protocol for use by the patient and his/her partner:
• Complete abstinence from sexual intercourse when this is in line with the preferred and usual lifestyle of the patient
• Double barrier methods
• Condom with spermicide in conjunction with use of an intrauterine device
• Condom with spermicide in conjunction with use of a diaphragm
• Surgical sterilization (bilateral oophorectomy with or without hysterectomy, tubal ligation or vasectomy) at least 6 weeks prior to taking study treatment. In the case of oophorectomy alone, only when the reproductive status of the woman has been confirmed by follow-up levels of luteinizing hormone (LH), follicle-stimulating hormone (FSH), and/or estradiol
• Non-hormonal intrauterine device used as directed by provider placing this is also acceptable.

You may not qualify if…

• Pre-existent peripheral neuropathy that is unrelated to chemotherapy
• Recurrent ovarian or endometrial cancer
• Diabetes managed by medication
• Neutrophils < 1,000 cells/m3
• Hemoglobin < 8.0 g/dcl
• Platelets < 100,000 cells/m3
• Creatinine clearance < 30 ml/min
• aspartate aminotransferase (AST) or alanine aminotransferase (ALT) values > 2.5 X upper limits of normal
• Total bilirubin > 2.0 X upper limits of normal
• Heavy alcohol use defined at > 8 drinks/week by women or 12 drinks/week by men
• Psychiatric illness that, in the opinion of the investigator, would interfere with the ability of the individual to participate in or complete the study.
• Pregnancy
• Current imprisonment
• Limitations of self-expression, defined as an inability to answer questions posed by physicians, nurses, care-givers, or other members of the investigative team or an inability to describe somatosensations.
• Known HIV
• Regular use of nutritional supplements that contain nicotinamide riboside (e.g. NIAGEN, TRuNIAGEN, Basis, NAD+ Cell Regenerator) within the previous 30 days
• Use of duloxetine (Cymbalta®) or any other drug for treatment of peripheral neuropathy such as gabapentin, pregabalin, lamotrigine, or amitryptyline.
• Pancreatic insufficiency requiring exocrine enzyme replacement therapy
• GI conditions where malabsorption of B complex vitamins is known to occur.
• Breastfeeding
• Allergy to epinephrine or local anesthetics
