FDA approves new dosing for Bristol-Myers Squibb's Opdivo
By Reuters Staff
(Reuters) - Bristol-Myers Squibb Co said on Tuesday the U.S. Food and Drug Administration had approved a four-week dosing schedule for its cancer drug, Opdivo (nivolumab).
Opdivo with a two-week dosing schedule was previously approved to treat a number of cancers such as melanoma.
The drug belongs to a fast-growing class of drugs called PD-L1 or PD-1 inhibitors that help the immune system attack cancer by blocking a mechanism tumors use to evade detection.
William Blair analyst Matt Phipps in a client note said the new approval may help the drug expand into the "maintenance and adjuvant therapy settings". Maintenance therapy immediately follows initial treatment to keep patients cancer-free if they go into remission.
The company said on Tuesday the drug was also approved for shorter 30-minute infusions, reducing previous infusion time in half.
"Cutting the number of infusions in half with the four-week dosing schedule provides meaningful benefit to patients and reduces the burden at infusion centers," said Phipps.
The analyst added that Bristol-Myers is testing Opdivo in nine late-stage adjuvant trials and as maintenance therapy in small-cell lung cancer.
Other PD-1 inhibitors include drugs from rivals such as Merck & Co and Roche.
The FDA decision makes Opdivo the only PD-1 inhibitor to offer every four-week dosing, according to the company.(c) Copyright Thomson Reuters 2018. Click For Restrictions - http://about.reuters.com/fulllegal.asp
