Introduction to Amifostine
Amifostine, also known as WR-2721, is a cytoprotective agent designed to protect normal tissues from the damaging effects of chemotherapy and radiation therapy. It has been proven effective in reducing the side effects associated with these treatments without compromising the efficacy of the cancer therapy itself.
Clinical Trials and Efficacy
Phase III Trials in Ovarian Cancer
In a pivotal phase III trial involving 242 patients with advanced ovarian cancer, amifostine significantly reduced hematological, renal, and neurological toxicities associated with chemotherapy. Patients receiving amifostine along with cisplatin and cyclophosphamide had fewer treatment delays, discontinuations, and hospitalizations compared to those receiving chemotherapy alone[1].
Head and Neck Cancer
Another phase III trial in 303 patients with head and neck cancer undergoing irradiation therapy showed that amifostine significantly reduced the incidence of acute and late-grade xerostomia (dry mouth). However, it did not significantly reduce mucositis in this patient group, although smaller trials have indicated some benefit in this area[1].
Lung Cancer
Amifostine has also demonstrated protective effects against pneumonitis and esophagitis in patients with lung cancer receiving thoracic irradiation in a preliminary report from a phase III trial involving 144 patients[1].
Pediatric Oncology
A phase III trial (ARAR0331) sponsored by the National Cancer Institute (NCI) and conducted by the Children’s Oncology Group is studying the efficacy of radiation therapy, amifostine, and chemotherapy in treating young patients with newly diagnosed nasopharyngeal cancer. This trial aims to determine how well these combined treatments work in killing tumor cells while protecting normal cells from radiation therapy side effects[4].
Mechanism of Action
Amifostine protects normal tissues by being more readily converted and taken up by these tissues compared to neoplastic (cancerous) tissues. The active metabolite, WR-1065, is responsible for this selective protection, ensuring that the tumor response to chemotherapy and radiation is not compromised[1].
Safety and Tolerability
At the recommended dose and schedule, amifostine is generally well tolerated. Common adverse effects include nausea, vomiting, transient hypotension, somnolence, and sneezing. These side effects are usually reversible and manageable[1].
