Nelfinavir in Recurrent Adenoid Cystic Cancer of the Head and Neck

2014-07-24 14:10:02 | BioPortfolio

Summary

The purpose of this study is to evaluate the FDA-approved drug nelfinavir (NFV) as an oncologic agent for adenoid cystic cancers of the head and neck.

Specifically, subjects will be asked to take 1250 mg twice daily and follow-up with their medical oncologist as clinically indicated while taking this medication.

Subjects would be evaluated for quality of life issues utilizing the EORTC QLQ-C30 2-page questionnaire.

Subjects would also be evaluated clinically by the oncologist to determine if the NFV was having an anti-neoplastic effect.

Description

The hypothesis of this study is that nelfinavir, by inhibiting the Akt and MAPK pathways, can inhibit adenoid cystic carcinoid growth. These cancers are heavily dependent on these signalling pathways.

Adenoid cystic carcinomas (ACC) are rare and account for about 1% of all head and neck cancers. They stem from salivary glands and are known for their tendency to spread along nerve sheaths (perineural spread). ACC is known for its prolonged clinical course, multiple recurrence and the delayed onset of distant metastases. The median/mean age at presentation is 47-56. Although 5 year disease free survivals (DFS) are 65-70%, the 15 year DFS drops to 30-40%. If followed long enough, 35% of patients will eventually develop metastatic disease.

The most common treatment of ACC is surgery followed by post-operative radiotherapy. When ACC recurs, management options are often limited both by the morbidity and low efficacy of re-irradiation and repeated surgical resection. Reported response rates to chemotherapy are low and when it occurs, the duration of the response is short lived.

In an effort to explore possible targeted therapies for patients with recurrent ACC, Dr. Gupta's lab examined the activation of 3 signaling proteins (EGFR, Akt, and MAPK) in 9 different paraffinized tissue blocks. Initial indications from in vitro studies demonstrates NFV is tumoricidal at clinically achievable concentrations. To explore the clinical benefit of this FDA-approved medication, we seek to implement its off label use in patients who have failed all other therapies and have no other therapeutic options left.

Medical and Biotech [MESH] Definitions

Carcinoma characterized by bands or cylinders of hyalinized or mucinous stroma separating or surrounded by nests or cords of small epithelial cells. When the cylinders occur within masses of epithelial cells, they give the tissue a perforated, sievelike, or cribriform appearance. Such tumors occur in the mammary glands, the mucous glands of the upper and lower respiratory tract, and the salivary glands. They are malignant but slow-growing, and tend to spread locally via the nerves. (Dorland, 27th ed)

A cystic growth originating from lymphatic tissue. It is usually found in the neck, axilla, or groin.

A potent HIV protease inhibitor. It is used in combination with other antiviral drugs in the treatment of HIV in both adults and children.
