April 30 (Reuters) – Amgen on Thursday said its first-quarter product sales rose 4%, helped by demand for cholesterol and rare disease medicines, as it moves forward with a broad development program for experimental ​weight-loss drug MariTide.

The company’s shares, which rose 2.4% in regular trading, were ‌down 2% at $339 after hours.

The California-based biotech company’s adjusted earnings per share rose 5% to $5.15, beating analysts’ expectations of $4.76, according to LSEG data.

Quarterly revenue rose 6% from a year earlier to $8.6 billion, matching the average Wall Street estimate, despite lower demand for its bone disease drugs.

First-quarter product ‌sales ​rose 9% by volume, while net prices and inventory ⁠levels each fell 2%, resulting ⁠in 4% quarter-over-quarter sales growth.

CEO Robert Bradway, speaking on a conference call, said Amgen’s confidence in MariTide continues to grow. The company has launched two new studies, including a trial to see how patients do when switching from ​a weekly injectable GLP-1 drug to MariTide, which is given just four or six times a year, he said.

Amgen is conducting a broad range of Phase ⁠3 trials of MariTide across obesity and related ⁠conditions, including heart disease and sleep apnea.

Earlier this week, the ​U.S. Food and Drug Administration proposed withdrawing approval of Amgen’s autoimmune disease drug Tavneos, ​citing a lack of proven effectiveness and what it described as false ‌statements in the original application.

Amgen said it is engaging with the agency and has submitted a label amendment that would provide more information on liver toxicity related to the drug, which saw first-quarter sales rise 32% to $114 million.

“We are confident in ⁠the risk/benefit profile of this medicine,” Amgen Chief Scientific Officer Jay Bradner said.

Quarterly sales of cholesterol drug Repatha rose 34% to $876 million, beating the average analyst estimate of $835 million.

Repatha ⁠sales were the “standout” for ‌the quarter, Citi Research analyst Geoffrey Meacham said in a ⁠note. Results for other products were mixed and Amgen’s ​slight increase ‌in its full-year outlook “does not meaningfully change the narrative,” he ​added.

Sales of ⁠osteoporosis drug Prolia fell 34% to $727 million, missing analysts’ estimates of $831 million, as patent expirations led to increased competition.

For full-year 2026, Amgen slightly raised its outlook for adjusted earnings per share to between $21.70 and $23.10, from a previous forecast of $21.60 to $23.00. Its revenue estimate was bumped up to $37.1 billion to $38.5 billion, from $37 billion to $38.4 billion.
