Trial of BMX-001 or Placebo in Head and Neck Cancer Patients

There are an estimated 65,000 newly diagnosed cases of head and neck cancer each year in the United States. The most common treatment for head and neck cancers is radiotherapy in combination with cisplatin chemotherapy. This treatment regimen is effective in killing the tumor; however, the normal tissues that line the mouth and throat can sustain severe injury from the radiation. Side-effects incurred during irradiation include: mucositis, xerostomia, swelling, trouble swallowing, pain, infections, cavities, hair loss and reddening of the skin. Some of these side effects can be so severe that patients require feeding tubes and management of severe pain can lead to the premature halt of radiotherapy. There are currently no effective radio-protectors used to ameliorate these severe side-effects. BioMimetix has developed small molecular weight superoxide dismutase (SOD) mimetic, BMX-001, that is a very potent radio-protector of head and neck tissues. In our first clinical trial in a head and neck cancer patient cohort using this drug, we have early evidence that BMX-001 may protect against radiation-induced mucositis and xerostomia. This will be a randomized, placebo-controlled Phase 2 clinical trial to study the effects of BMX-001 (14 mg/subject biw) + radiation therapy + cisplatin against placebo + radiation therapy + cisplatin in prevention of acute and chronic mucositis and xerostomia.
