Novartis reports 3,878 suspected cases of drug side effects
Novartis Pharma K.K. said Wednesday that it suspects a total of 3,878 cases of severe side effects related to drugs sold by the company after discovering documents on around 10,000 cases were left unattended.
To examine the causal relationships between the drugs and possible side effects, the Japanese sales arm of Swiss pharmaceutical giant Novartis will conduct a detailed investigation into doctors who diagnosed patients and submit further reports to Japan's health ministry, it said.
The Ministry of Health, Labor and Welfare, which was informed of the cases of suspected side effects on Tuesday, said it will consider its response after seeing the additional reports.
Of the 3,878 cases, 1,934 were related to Glivec and 813 involved Tasigna, both used to treat chronic myelocytic leukemia.
"We deeply apologize for causing great worry to patients and trouble to medical experts because of a delay in reporting side effects, which is extremely important for a pharmaceutical company," Novartis said in a statement.
In June, Novartis said it had left documents regarding suspected side effects unattended, mainly because employees in charge of sales did not share the information with the department for safety management.
The pharmaceutical affairs law requires pharmaceutical companies to report information on severe side effects to the government within a certain period of time.
