Effect of Pentoxifylline on Preventing Chemotherapy-induced Toxicities in Patients With Breast Cancer

July 24, 2025 updated by: Omar Hamdy, Mansoura University
This clinical trial is a randomized clinical trial that aims to assess the usefulness of adding pentoxifylline to the neoadjuvant chemotherapy treatment protocol of doxorubicin/cyclophosphamide fllowed by taxane for breast cancer patients to decrease the incidence of developing toxicities, and enhance the quality of patient life using the EQ-5D-3L questionnaire. The participant will administer Pentoxifylline oral tablets three times per day along with the treatment protocol, starting from the first doxorubicin/cyclophosphamide cycle till the end of the chemotherapy cycles. The researchers will compare the incidence and grade of mucosities, neuropathy, and other chemotherapy-related toxicities in the presence or absence of oral pentoxifylline.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
The incidence of grade 2 or more peripheral neuropathy in the two groups using Common Terminology Criteria Adverse Event grading
Time Frame: 6 months
The number of patients reported grade 2 or more peripheral neuropathy in the two groups.
6 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
