A doctor specialized in treating cancer patients was charged on Friday with illegally imported chemotherapy drugs from Honduras and India.

Dr. Vinod Chandrashekm Patwardhan, 58, from Claremont, was released the same day on a $2 million bond and required to wear an electronic device while out on bail, Thom Mrozek, spokesman for the US Attorney’s Office, said.

Dr. Parwardhan was arrested at his medical office on Foothill Boulevard and charged with one count of delivering misbranded drugs into interstate commerce. If convicted, he could risk up to three years in federal prison. He is scheduled to return to court September 17 for arraignment.

The investigation on Dr. Parwardhan started in April after one of his employees said the doctor was treating patients with cheaper cancer medications imported from India and Honduras, which were not approved in the US by the Food and Drug Administration. None of the investigators could tell for sure how many patients were treated with the drugs and who suffered negative effects as a result of taking the drugs.

According to the complaint, Dr. Patwardhan treated about 35 cancer patients a week and administered partial dosage of these illegal drugs to patients undergoing chemotherapy.

There is also an invoice dated Feb. 3 signed by the doctor, according to which he approved the $888,900 purchase of 100 vials of Docetax 80 mg and 300 vials of two other drugs, also illegible. Docetax is used in India for metastatic breast cancer. Other drugs included Pemnat 500 mg, Neupeg and Grafeel 1 ml, made in India and Farmorubicina manufactured in Italy.

“This is the first case that I’ve seen in my 12 years in a situation where you have patients with legitimate and serious problems who are receiving a drug that is not authorized by the Food and Drug Administration,” Mrozek said.
