A diagnosis of CIPN should be supported by i) onset of pain in hands or feet after exposure to taxanes or platins, ii) presence of painful symptoms in a symmetrical stocking and/or glove distribution, AND iii) painful symptoms may be accompanied by nonpainful symptoms (eg, tingling/pins and needles intensity and numbness intensity).
  6. Patients who have stopped their chemotherapy treatment with taxanes or platins or any other neurotoxic chemotherapy for ≥24 weeks at the time of the screening visit.
  7. Patients with CIPN pain for ≥24 weeks at the time of the screening visit.
  8. Patients with a mean value of pain intensity ≥4 and ≤9 in target study extremities (left and right feet or left and right hands) on the 11 point NPRS at baseline.
  9. Patients with symmetrical stocking or glove distribution pain, NPRS (≤1 point difference) in the target study extremities at screening.
  10. Neuropathic Pain (DN4) score ≥4 in the target study extremities (hands or feet) at the screening visit
  11. Treatment naïve patients or patients in whom any prior CIPN treatment (except oral amitriptyline [AMT]) has not been modified during the 4 weeks preceding the screening visit and is planned to be maintained at the same regimen during the course of the study (prior treatment includes pharmacological and nonpharmacological treatments).
  12. Male patients should agree to use a condom along with another medically acceptable contraceptive method, where applicable according to local guidelines, if he is engaged in sexual activity with a woman of childbearing potential (WOCBP) from the day of the signature of the informed consent and up to 90 days after the End-of-Study (EoS) Visit. Male patients should agree not to donate sperm until 30 calendar days after the last dose of study drug.

  13. Females must comply with the following in order to be enrolled:

    1. WOCBP with negative serum pregnancy test results can be enrolled only if willing to use an acceptable contraceptive method, ie, oral contraceptives, patch contraceptives, injection contraceptives, implantable hormonal contraceptives, male condom with intravaginal spermicide, diaphragm or cervical cap with spermicide, vaginal contraceptive ring, intrauterine device or system, surgical sterilization (hysterectomy, bilateral oophorectomy, and/or bilateral salpingectomy), tubal ligation/occlusion, vasectomized partner, or sexual abstinence, if this is the patient's current practice, from at least 14 days prior to the screening visit and throughout the study and for at least 30 days after the completion of the study.
    2. Or surgically sterilized for at least 6 months.
    3. Or menopausal for at least 1 year.

Exclusion criteria

  1. Patients who are not compliant in completion of pain ratings during the screening period.
