Assessing the Clinical Utility of Adding Pentoxifylline to Neoadjuvant Chemotherapy Protocols in Breast Cancer Patients"

Phase 2
Active, not recruiting
Conditions
Breast Cancer Female
Interventions
Registration Number
NCT06176339
Lead Sponsor
Mansoura University
Brief Summary

Breast cancer, a leading cause of cancer-related mortality in women worldwide, has spurred the investigation of novel therapeutic approaches. Pentoxifylline (PTX), a synthetic methylxanthine derivative, has shown promise in preclinical studies when combined with conventional anticancer drugs. This study aims to assess PTX's impact when added to neoadjuvant chemotherapy protocols in breast cancer patients, with the goal of improving treatment outcomes and reducing associated toxicities.

GroupInterventionDescription
Pentoxyphyllin groupPentoxifylline Oral TabletPatients will undergo a treatment plan determined by the multidisciplinary team. This involves four cycles of intravenous (IV) doxorubicin at a dose of 60 mg/m2 along with IV cyclophosphamide at 600 mg/m2 per cycle. Following this, taxane will be administered. Additionally, patients are prescribed 400 mg pentoxifylline tablets to be taken three times daily.
Control groupPlaceboPatients will undergo a treatment plan determined by the multidisciplinary team. This involves four cycles of intravenous (IV) doxorubicin at a dose of 60 mg/m2 along with IV cyclophosphamide at 600 mg/m2 per cycle. Following this, taxane will be administered. Additionally, patients will take placebo tablets three times daily.
