Big pharma M&A for autoimmune T-cell engagers
UCB agreed to acquire Candid Therapeutics for up to $2.2 billion, expanding its presence in T-cell engager (TCE) antibodies for immunology indications. The deal adds Candid’s bispecific and trispecific pipeline, including the BCMA/CD3 asset cizutamig, as UCB positions the strategy as an “immune reset” play. Under the terms announced May 3, UCB will pay $2.0 billion up front and up to $200 million in milestones. Candid is privately held and based in San Diego, with a portfolio that includes cizutamig (in multiple Phase I programs across autoimmune indications and multiple myeloma) and other early-stage B-cell-targeting CD20 x CD3 and CD19/CD20 x CD3 candidates. Candid’s assets include licenses tied to China-made biologics, underscoring how Western partners are continuing to build TCE pipelines with content sourced from Chinese biotechs. The acquisition also ends Candid’s prior plan to pursue a reverse merger involving Rallybio.

Gene therapy market pull-forward amid FDA attention
A conference report from Rome highlighted how FDA decisions are shaping sentiment for the gene therapy and cell therapy sector, even as industry leaders look for opportunities in Europe. The discussion centered on recent approvals of rare disease treatments and continued concerns about the regulatory roadblocks that can delay programs. The piece also flagged leadership churn inside FDA’s vaccine and gene/cell therapy apparatus, pointing to the departure of Vinay Prasad, who previously served as a top regulator of gene and cell therapies as well as vaccines. That personnel shift is being watched closely by stakeholders as they plan development and regulatory strategy. While the full details of future policy actions were not provided, the immediate takeaway for biotech teams is that FDA is continuing to set the pace for both approval expectations and operational risk in gene therapy development.

Phase 3 momentum for cell-free, at-home chronic thyroid eye disease therapy
Viridian Therapeutics reported top-line success from its Phase 3 Reveal-2 program for elegrobart in chronic thyroid eye disease, positioning the company for a U.S. BLA filing in the first quarter of 2027. The trial met both primary endpoints: a proptosis responder rate and an overall responder rate required for U.S. and EMA submissions. Elegrobart is a half-life extended monoclonal antibody against the IGF-1 receptor, delivered subcutaneously via an autoinjector designed for at-home use. If approved, it would compete in a market currently defined by Amgen’s Tepezza (teprotumumab) and a separate in-development Viridian therapy (veligrotug), which is under FDA review. The near-term industry implication is that convenience and dosing design are becoming central differentiators in autoimmune ophthalmology, with late-stage execution increasingly focused on outpatient administration workflows.

Phase 3 readout lifts confidence in heart drug across hypertrophic cardiomyopathy subtype
Cytokinetics scored a Phase 3 win for aficamten (brand name Myqorzo) in symptomatic non-obstructive hypertrophic cardiomyopathy (nHCM), meeting twin primary endpoints in the pivotal Acacia-HCM trial. The study showed statistically significant improvements versus placebo at week 36 in patient-reported outcomes and maximal exercise performance. The results extend Cytokinetics’ cardiomyopathy franchise beyond obstructive HCM, where aficamten was cleared by the FDA in December. With continued commercialization early in the launch cycle, a regulatory green light for nHCM could substantially widen the treatable population. For biotech planning, the catalyst is straightforward: nHCM endpoint success is the kind of clinical evidence that can accelerate payer conversations and companion labeling expansions if regulators agree with the Phase 3 data package.

Clinical trial progress and regulatory pathway mapping in CAR-T localization
South Korea’s Ministry of Food and Drug Safety (MFDS) approved Curocell’s Rimqarto (anbalcabtagene-autoleucel; anbal-cel) as the first homegrown CAR T therapy for patients with advanced diffuse large B-cell lymphomas. The approval marks a milestone for domestic CAR-T development in a segment long dominated by global players. Rimqarto’s authorization positions Curocell to compete on local manufacturing and regulatory execution as CAR-T adoption continues to expand across oncology indications. The “first homegrown” framing also signals that national regulators and payers may be more willing to support additional localized cell therapy programs. For biotech teams, the key operational angle is timing: MFDS clearance indicates that South Korea can now point to a successful precedent for future approvals of similar next-generation CAR-T candidates.
