The Possible Protective Role of Ketotifen Against Oxaliplatin Induced Peripheral Neuropathy

Q: Who can participate in NCT05624138?

Eligibility for this trial depends on the specific inclusion and exclusion criteria set by the sponsor. The plain-English summary above translates the most important criteria into accessible language; the official clinical text is preserved in the collapsible section underneath. Whether you fit any specific trial is a medical decision your doctor needs to confirm — bring the trial information to your treating physician for a full review against your medical history.

Q: How do I contact the trial site for NCT05624138?

Contact information registered with ClinicalTrials.gov is shown in the sidebar of this page. Before reaching out, confirm with your treating physician that this trial is appropriate for your situation. The trial site will then walk you through the screening process to determine final eligibility.

Q: Is participating in a clinical trial safe?

Clinical trials in the United States are regulated by the FDA and overseen by Institutional Review Boards (IRBs) that review the protocol for safety. Risk varies by trial — Phase 1 studies test new treatments in humans for the first time, while Phase 3 trials use treatments that have already passed earlier safety screening. The informed consent document for any specific trial details the known risks and what to expect. Discuss those risks with your physician before deciding whether to participate.

The Possible Protective Role of Ketotifen Against Oxaliplatin Induced Peripheral Neuropathy in Patients With Colorectal Cancer

The Possible Protective Role of Ketotifen Against Oxaliplatin Induced Peripheral Neuropathy (NCT05624138) is a Phase 3 interventional studying Neuropathy;Peripheral, sponsored by Tanta University. RECRUITING as of the most recent ClinicalTrials.gov update. Talk to your doctor before contacting the trial site.

About This Trial

The aim of current study is to evaluate the possible protective role of Ketotifen against oxaliplatin-induced peripheral sensory neuropathy in patient with stage III colorectal cancer. This study will be a randomized placebo controlled parallel study.64 patients with colorectal cancer will be randomized to 2 groups: Group I (control group; n=32) which will receive 12 cycles of modified FOLFOX-6 regimen plus placebo tablets twice daily. Group II (ketotifen group; n=32) which will receive modified FOLFOX-6 regimen in addition to ketotifen 2 mg daily Blood sample collection and biochemical assessment: * Serum IL-6 as a marker of inflammation. * Serum superoxide dismutase (SOD) as a biomarker of oxidative stress. * Serum neurotensin as a biomarker for neuropathy. Assessment of oxaliplatin induced peripheral sensory neuropathy will be done through: * The implication of National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE, Version 5, 2017) for grading of neuropathy at baseline and by the end of every two oxaliplatin cycles. * The use of Neurotoxicity- 12 item questionnaire score (Ntx-12) from the validated Functional Assessment of Cancer Therapy/Gynecologic Oncology Group "FACT/GOG-Ntx-12" at baseline and by the end of every two oxaliplatin cycles. * The assessment of the severity of neuropathic pain through brief pain inventory short form "BPI-SF" worst item. Severity of neuropathic pain will be assessed at baseline and by the end of every two oxaliplatin cycles.

What Stage of Research Is This?

Phase 3 trials confirm efficacy and safety in large patient groups (often 300–3,000+) and form the evidence base for an FDA approval submission. For Neuropathy;Peripheral, Phase 3 studies typically randomize participants between the investigational treatment and either a placebo or current standard of care. A successful Phase 3 result is the threshold most treatments need to clear before regulatory approval.

This trial is currently recruiting participants. The sponsor has registered the study with ClinicalTrials.gov as actively enrolling, which means new applicants who meet the eligibility criteria can be considered for screening. Trial status can change between updates — confirm current recruiting status with the study contact before traveling for a screening visit.

Target enrollment of 64 participants puts this in the typical range for a Phase 2-style efficacy study or a moderate Phase 3 trial in a focused Neuropathy;Peripheral subpopulation. At this scale, the study has enough statistical power to detect a clear treatment effect but is not the largest cohort in the field.

Who May Be Eligible (Plain English)

Who May Qualify: - Patients with diagnosed by tissue sample (biopsy-confirmed) diagnosis of Stage III colorectal cancer. - Patients who will be scheduled to receive modified FOLFOX-6. - Patients with no contraindication to chemotherapy. - Males and females aged ≥ 18 years old. - Adequate baseline hematologic values (absolute neutrophilic count ≥ 1.5 × 109/L, platelet count ≥ 100 × 109/L and hemoglobin level ≥ 10 g/dl). - Patients with adequate renal function (serum creatinine \< 1.5 mg/dl or creatinine clearance (ClCr) ˃ 45 mL/min). - Patients with adequate liver function (serum bilirubin \< 1.5 mg/dl). - Patients with performance status 0-1 according to Eastern Cooperative Oncology Group (ECOG) score. Who Should NOT Join This Trial: - Children \< 18 years old. - Prior exposure to neurotoxic chemotherapy (Oxaliplatin, cisplatin, vincristine, paclitaxel, or docetaxel, INH) for at least 6 months prior the study treatment. - Evidence of pre-existing peripheral neuropathy resulting from another reason (diabetes, brain tumor, brain trauma). - Patients with diabetes and other conditions that predispose to neuropathy as hypothyroidism, autoimmune conditions (where your immune system attacks your own body)s, hepatitis C. - History of known allergy to oxaliplatin or other platinum agents. - Patients with other inflammatory or stressful conditions. - Patients with glaucoma, cataract, other chronic eye disease, seizure, diabetes, heart diseases, low blood pressure, dizziness, vertigo, ménière's disease and CNS disorders. - Concomitant use of multivitamins (vitamins E, C, A), tricyclic antidepressants, other neuro-protective medications (gabapentin, lamotrigine, carbamazepine and phenytoin, etc…). - Patients on amifampridine, bupropion and donepezil. - Concurrent active cancer originating from a primary site other than colon or rectum. - Pregnant and breastfeeding women. Always talk to your doctor about whether this trial is right for you.
