Ionis Pharmaceuticals announced its fourth-quarter and full-year 2024 results.

Here's a recap of the week’s most important stories.

IONS’ Better-Than-Expected Q4 Results

IONS reported better-than-expected top and bottom-line numbers for the fourth quarter. Its loss of 66 cents per share was narrower than the Zacks Consensus Estimate of a loss of $1.12 per share. Total revenues of $227 million beat the Zacks Consensus Estimate of $137.5 million. However, revenues declined 30.2% year over year. Commercial revenues were $86 million in the fourth quarter, up 8.9% year over year. R&D revenues declined 42.7% year over year to $141 million.

Ionis issued fresh financial guidance for 2025. The company expects total revenues to be more than $600 million in 2025. Adjusted operating loss is expected to be less than $495 million.

EU Approval to Merck’s Welireg for Two Indications

The European Commission approved Merck’s Welireg as a monotherapy for certain previously treated patients with advanced renal cell carcinoma and certain patients with von Hippel-Lindau disease-associated tumors. Approvals for these two indications were based on data from the LITESPARK-004 and LITESPARK-005 studies. Welireg is already approved for both indications in the United States.

FDA’s Priority Tag to SNY’s Dupixent sBLA for Bullous Pemphigoid

Sanofi and Regeneron announced that the FDA has accepted and granted priority review to an sBLA seeking approval of Dupixent for treating bullous pemphigoid, a chronic, debilitating, and relapsing skin disease. The FDA’s decision on the sBLA is expected by June 20, 2025. The sBLA is based on data from a pivotal study, which demonstrated that Dupixent led to significant improvements in sustained disease remission compared to placebo in adult patients with moderate-to-severe bullous pemphigoid.
