Whether Pfizer’s Metsera buy finally unlocks follow-on obesity dealmaking among latecomer big pharmas watching GLP-1s from the sidelines.

How fast Merck can push CD388 through late-stage flu prevention trials and whether competitors respond with rival long-acting antivirals or combo vaccine strategies.

If the FDA’s Elevidys decision becomes a template for narrowing high-risk gene therapy labels in neuromuscular and metabolic rare diseases.

Pfizer clinches the Metsera obesity saga
Pfizer sealed its long-running bidding war for Metsera, agreeing to pay up to $10 billion after matching and then outmaneuvering Novo Nordisk’s rival offer, securing a GLP-1 portfolio that showed up to 14.1% weight loss in trials. 👉 Read more

Merck drops $9.2B on Cidara’s long-acting flu antibody
Merck agreed to acquire Cidara Therapeutics for about $9.2 billion, more than doubling Cidara’s valuation and betting that CD388 can become an alternative to flu vaccines for up to 100 million high-risk patients. 👉 Read more

The FDA imposed its strongest warning on Sarepta’s Elevidys, citing fatal acute liver failure in non-ambulatory patients and restricting use to ambulatory boys aged ≥4 years, with closer liver monitoring. 👉 Read more

Withings’ “thermometer of the future” gets FDA green light
French medtech Withings secured U.S. clearance for BeamO, a handheld multi-sensor that combines ECG, digital stethoscope, and thermometer into a single home “check-up” device aimed at rapid cardio-pulmonary triage. 👉 Read more

Elevidys decision raises the safety bar in neuromuscular gene therapy
The FDA’s boxed warning and label narrowing for Elevidys underscore that serious liver events, even in small numbers, can trigger label reversals in already-approved gene therapies. 👉 Read more

Merck’s Cidara buy echoes rare-disease style valuations
Although centered on flu prevention, Merck’s $9.2B price tag for Cidara mirrors rare-disease M&A multiples, reflecting willingness to pay a triple-digit premium for assets with strong late-stage data in high-risk, defined populations. 👉 Read more

Advanced neuromuscular RNA therapies stay in the crosshairs
In parallel to this week’s deals, Novartis’ pending $12B acquisition of Avidity Biosciences continues to signal enthusiasm for RNA-based approaches in genetically defined neuromuscular disease, setting a high bar for future partnering and exits in the category. 👉 Read more

Biosimilar guidance moves away from mandatory efficacy trials
The FDA’s new draft guidance on biosimilars, highlighted in multiple November alerts, proposes that sponsors often can skip comparative efficacy trials if analytical and PK data show high similarity, potentially shaving years and major cost off development. 👉 Read more

Digital and AI tools increasingly central in trial design and portfolio strategy
Industry analyses this month emphasize how AI, digital twins, and in-silico models are being used to prioritize indications and streamline trial design, particularly in cardiometabolic and oncology programs tied to large, long-term outcomes. 👉 Read more

Human-centric neurotech and device-drug convergence
November round-ups point to rapid progress in implanted neurotech, most notably Synchron’s $200M raise to advance a brain-computer interface toward commercial launch, highlighting the convergence of device, software, and CNS therapeutics. 👉 Read more

Two megadeals anchor a resurgent M&A tape
With Pfizer–Metsera (up to $10B) and Merck–Cidara ($9.2B) both landing in the same week, cardiometabolic and infectious disease now dominate 2025’s megadeal list and reinforce buyer appetite for late-stage, de-risked assets. 👉 Read more

Medtech capital flows favor robotics scale-ups
Cornerstone Robotics closed an oversubscribed ~$200M round to accelerate commercialization of its Sentire endoscopic surgical system and global expansion, helped by backing from Hong Kong’s sovereign investor. 👉 Read more

Layoffs and portfolio pruning continue at smaller biotechs
Sector layoff trackers show continued headcount reductions and pipeline rationalizations at emerging biotechs, as companies trade therapeutic breadth for longer cash runways in a still-constrained financing environment. 👉 Read more

FDA biosimilar framework aims to cut costs via fewer trials
The updated biosimilar guidance, discussed widely this month, would allow many biosimilar developers to rely primarily on analytical and PK data, reducing or eliminating large efficacy trials and potentially accelerating competition for blockbuster biologics. 👉 Read more

UK and Europe face mounting pressure over drug pricing and investment
Senior voices, including AstraZeneca’s CEO and the U.S. ambassador to the UK, warned that under-payment for innovative drugs is already triggering paused investments and relocations, with nearly £2 billion in UK projects reportedly on hold. 👉 Read more

Life-sciences funding reforms under review in the UK
A new British Business Bank evaluation of the Life Sciences Investment Programme underscored the persistent funding gap for growth-stage UK life-sciences companies, keeping pressure on policymakers to refine public–private capital schemes. 👉 Read more

M&A size and focus are shifting, not shrinking
Biotech deal-value in 2025 YTD is about $49B, already above 2024’s $44B total, an increase of roughly 11% and driven by megadeals like obesity and neuromuscular assets.

Deal volume is modestly higher than historical norms
A recent analysis finds 2025 averaging 21 deals versus a long-term average of 19, about a 10% uplift in volume as large pharmas lean on M&A to address upcoming patent cliffs.

November medtech and neurotech financings highlight platform plays
Between Cornerstone Robotics’ $200M surgical robotics round and Synchron’s $200M BCI financing, November has already seen at least $400M in large, platform-oriented medtech and neurotech raises.

Obesity remains the gravity well for capital
Commentary around Pfizer–Metsera notes that 2025 obesity-focused deals are increasingly setting valuation benchmarks for cardiometabolic assets, attracting both strategic buyers and late-stage crossover capital.

Biotech capital markets are stabilizing, not roaring back
Public biotech benchmarks are up low double digits year-to-date, yet private funding and IPO volume remain selective, rewarding late-stage, de-risked stories and well-differentiated platforms over broad early-stage pipelines.

This week’s headline M&A value: ~$19.2B across Pfizer–Metsera (~$10B) and Merck–Cidara (~$9.2B).

M&A trendline: 2025 biotech M&A value ~11% above 2024 with multiple deals > $5B, compared with none in 2024.

Recent medtech platform financings: at least $400M this month in two deals (Cornerstone Robotics + Synchron).

Potential follow-up communications from Pfizer and Merck on integration timelines, synergy targets, and pipeline reprioritizations after Metsera and Cidara.
