Background and study aims
Breast cancer is the most common type of cancer worldwide. Treatments often include drugs called taxanes, such as docetaxel and paclitaxel. While these drugs are effective, they can cause a condition called chemotherapy-induced peripheral neuropathy (CIPN), which affects the nerves and leads to pain, numbness, and sometimes difficulty with movement. Nail problems like onycholysis (where nails separate from the nail bed) are also common. This study is testing a new gel called TAR-0520, developed by Tarian Pharma, to see if it can help prevent these side effects when applied to the hands.

Who can participate?
The study is open to cancer patients who are receiving treatments known to cause skin and nerve-related side effects, such as EGFR inhibitors and taxanes.

What does the study involve?
Participants will receive one of the following chemotherapy treatments:
-Docetaxel every 3 weeks for 4 cycles
-Docetaxel every 3 weeks for 6 cycles
-Paclitaxel every week for 12 cycles
During each cycle, participants will apply TAR-0520 gel to both hands, including the fingers, twice a day for three days. The first dose is applied two hours before chemotherapy. This routine is repeated with each new cycle.

What are the possible benefits and risks of participating?
The gel may help prevent painful nerve symptoms and nail problems, which could allow patients to continue their treatment without interruption and improve their overall quality of life. Previous studies have shown only mild skin irritation as a side effect, and the gel does not enter the bloodstream in significant amounts.

Where is the study run from?
The study is being conducted at Royal Green Hospital in Moka, Mauritius.

When is the study starting and how long is it expected to run for?
August 2024 to July 2026

Who is funding the study?
Tarian Pharma, France.

PhasePhase II
Drug / device / biological / vaccine name(s)TAR-0520 Gel
Primary outcome measurePeripheral neuropathy symptoms measured using the modified Chemotherapy-Induced Peripheral Neuropathy (CIPN) Patient-Reported Outcome (PRO) questionnaire (hands and feet subscales) at Day 1 (Week 1), Week 4, Week 7, Week 10, Week 13, Week 16, and at the follow-up visit 4 weeks after the last chemotherapy cycle
Secondary outcome measures1. Adverse events (AEs) collected through patient interviews and review of medical records at Day 1 (Week 1), Week 4, Week 7, Week 10, Week 13, Week 16, and at the follow-up visit 4 weeks after the last chemotherapy cycle
2. Physical examination (covering skin, lungs, abdomen, neurological function, musculoskeletal system, lymph nodes, cardiovascular system) conducted by the investigator at screening (Day -15), Day 1 (Week 1), and at the end of the study or early termination visit
3. Vital signs (systolic and diastolic blood pressure and pulse rate, measured after 5 minutes in sitting position) at screening visit, Day 1 (Week 1), Week 4, Week 7, Week 10, Week 13, Week 16, and at the follow-up visit 4 weeks after the last chemotherapy cycle

Lower age limit18 Years
SexBoth
Target number of participants10
Key inclusion criteria1. Adult patients
2. Cancer patients planned to be treated with taxane perfusions (docetaxel or paclitaxel) as part of their chemotherapy protocol. Any type of cancer requiring taxane treatment (breast, ovarian, prostate, urinary bladder, pancreatic or lung cancer) can be included. Taxane treatment can be the first or second line of treatment.
3. Patients, with or without metastasis, whose condition is considered stable and compatible with the participation to a clinical trial
4. Patients understand and agree to comply with the requirements of the clinical trial protocol.
5. Female patients of childbearing potential agree to use a highly effective method of contraception throughout the study. Highly effective method of contraception can be:
- combined (estrogen and progestogen containing) hormonal contraception associated with inhibition of ovulation (oral, intravaginal, transdermal)
- progestogen-only hormonal contraception associated with inhibition of ovulation (oral, injectable, implantable)
- intrauterine device (IUD)
- intrauterine hormone-releasing system (IUS)
- bilateral tubal occlusion
- vasectomized partner
- sexual abstinence
Key exclusion criteria1. Patients already treated with taxanes or other chemotherapies known to induce neuropathies in the past year
2. Patients with diagnosed peripheral neuropathy whatever its cause (Diabetes, Alcoholism, HIV, Peripheral vascular disease, Vitamin B deficiencies). Pre-diabetic patients without neuropathy can be included
3. Patients with concomitant therapies known to induce neuropathies
4. Patients treated for neuropathic pain
5. Patients who will not be able to follow the protocol for physical or psychological reasons
6. Patients currently receiving monoamine oxidase (MAO) inhibitors therapy or patients on antidepressants which affect noradrenergic transmission e.g. tricyclic antidepressants and mianserin (as mentioned in the current topical brimonidine labeling of approved products).
7. Female who is pregnant or lactating
8. Female who intends to conceive a child during the clinical trial
