Shares of Dr Reddy's Laboratories fell 6.5% to Rs 1,261 on the BSE on Thursday after the company said commercial supplies of its semaglutide product will be delayed following a quality-related issue linked to the active pharmaceutical ingredient (API) used in certain batches.

In an exchange filing, the company said certain batches of semaglutide were found to be out of specification due to an issue associated with the API used in the product. It added that an investigation is underway to identify the root cause and that appropriate measures are being taken to ensure product quality.

Dr Reddy's said commercial supplies of the product will be delayed until the issue is resolved. The company clarified that the development has no impact on patient safety or on the product's existing global regulatory filings. It also reiterated its commitment to ensuring reliable global supplies of the metabolic therapy.

Dr Reddy's further said its management will host a conference call to discuss the development and answer questions from participants.

The disclosure comes less than two months after Dr Reddy's commercially launched its oral semaglutide tablet under the brand name Obeda in India for the treatment of type-2 diabetes. The once-daily oral drug is available in 3 mg, 7 mg and 14 mg strengths, priced at Rs 99, Rs 135 and Rs 225 per tablet, respectively.

The company had positioned the launch as a key milestone in building its GLP-1 portfolio after also becoming one of the first companies to launch a generic once-weekly injectable semaglutide in India following the expiry of the relevant patent earlier this year.

The decline in quarterly earnings was primarily on account of reduced sales of Lenalidomide, price erosion in North America and Europe Generics and a one-time SSA impact.
