You may be eligible if
1. Male or female patients of 18 years and older.
2. Patients having signed a written informed consent prior to any study-related procedure.
3. Body mass index of 18 to 35 kg/m2 (inclusive).
4. With an estimated life expectancy ≥6 months at study entry.
5. Patients with painful sensory CIPN resulting from prior treatment of cancer with taxanes or platins. 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. Non target extremities can be treated regardless of the pain intensity.
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.
You may not be if
1. Patients who are not compliant in completion of pain ratings during the screening period. Patients having \<5 of 7 records of average pain intensity in the target study extremities from Day -7 to Day -1 will be excluded. If a patient misses records of 2 days out of 7 days, the patient will be included in the study; however, patients missing 3 or more days of records will be excluded from the study.
2. Clinical evidence of a preexisting painful peripheral neuropathy resulting from another cause than chemotherapy, eg, diabetic neuropathy, posttraumatic neuropathy, carpal/tarsal tunnel syndrome, radiculopathy, spinal stenosis, brachial plexopathy, or other preexisting symptomatic neuropathy due to alcoholism, vitamin B deficiency, hypothyroidism, human immunodeficiency virus. Patients may be included in the study, providing that pain appeared after chemotherapy, while other non-painful symptoms could have been present before start of chemotherapy.
3. Skin irritation, or lesions (eg open skin wounds, infections, inflammations, or exfoliative dermatitis) of any type on the hands or feet (or only on the hands if the study drug is not applied on the feet and vice versa \[only on the feet if the study drug is not applied on the hands\]).
4. Presence of glaucoma.
5. Presence of urinary retention (or significant prostatic hypertrophy at risk of urinary retention).
6. Angina or myocardial infarction in the year preceding screening visit.
7. History and/or presence of major depressive episode. Patients with a medical history of bipolar disorder, alcohol abuse, or psychotic disorder are also excluded.
8. Patients who are at significant risk of suicide, or are a danger to self or others, in the opinion of the investigator, based upon clinical interview and the C-SSRS at screening and baseline. Affirmative answer to suicidal ideation questions 4 or 5 within the last 6 months and / or suicidal behavior (actual attempt, interrupted attempt, aborted attempt, and/or preparatory acts/behavior) within the last 2 years are exclusionary.
9. Pregnant or lactating women.
10. Abnormality in the 12-lead electrocardiogram (ECG) at screening that in the opinion of the investigator increases the risk of participating in the study, such as a corrected QT Fridericia (QTcF) interval \>430 msec for males or \>450 msec for females.
11. A history of additional risk factors for Torsade de Pointe (eg, heart failure, hypokalemia, family history of long QT syndrome).
12. The use of concomitant medications within 24 weeks prior to Day 1 and/or during the study or the equivalent of 5 half-lives that prolong the QT/QTc interval, eg, Class 1 antiarrhythmics (eg, quinidine, disopyramide, procainamide) and Class 3 antiarrhythmics (eg, amiodarone, sotalol), first generation antihistamines (such as diphenhydramine, hydroxyzine, astemizole, terfenadine, and ebastine), antipsychotics known to prolong QT interval, and antimalarials (eg, mefloquine, quinine), tricyclic antidepressants (eg, AMT), tetracyclic antidepressants (eg, maprotiline), cisapride.
13. The use of monoamine oxidase inhibitors within 24 weeks (or the equivalent of 5 half-lives) prior to Day 1 and/or during the study.
14. The use of opioids within 4 weeks (or the equivalent of 5 half lives) prior to Day 1 and/or during the study.
15. History of illicit drug use or confirmed drugs of abuse at screening. Positive urine drug screen for prescribed medication is allowed at the discretion of the investigator.

17. Failure to respond to more than 2 analgesics (regardless of the route of administration) from different drug classes (including antidepressants and anticonvulsants) due to lack of efficacy to treat CIPN at any time in the past. The definition of failure to respond is left to the investigator's judgement and should be understood as exclusion of patients who are non-responding to more than 2 analgesics thought to be effective for neuropathic pain that were used at therapeutic doses in the 6 months prior to screening visit.
18. Treatment with oral or topical AMT or nortriptyline in the past 4 weeks prior to baseline visit.

28. The investigator considers the patient unfit for the study as a result of the medical interview, physical examination, or screening investigations, in particular any status or disease making the patient unable to follow instructions.
29. The patient is unable to apply the study drug on hands or feet.
30. The patient is an employee of the investigator, study site, sponsor, or CRO with direct involvement in the proposed study or other studies under the direction of the investigator, study site, or sponsor, or a family member of the site employee or the investigator.
