The legal battle over GLP-1 weight-loss and diabetes drugs is accelerating — and a pivotal shift is unfolding. Two distinct federal multidistrict litigation (MDL) tracks are taking shape, each carrying enormous implications for settlement values, case strategies, and plaintiff acquisition.
For law firms exploring Ozempic lawsuits and other GLP-1-related claims, understanding these parallel tracks now is critical to capturing early positioning before the litigation landscape matures.
MDL 3094 – Gastroparesis & Gastrointestinal Injuries
- Court: Eastern District of Pennsylvania
- Judge: Karen S. Marston
- Cases Pending: 2,676 (as of September 2, 2025)
- Status: 13th largest active federal MDL
- Bellwether Timeline: Expected early 2026
- Primary Injuries: Gastroparesis, intestinal blockages, severe vomiting, gallbladder disease
Launched less than two years ago, MDL 3094 has grown at breakneck speed — expanding from the first Ozempic lawsuit in August 2023 to nearly 2,700 consolidated cases. The rapid plaintiff volume and early judicial coordination make this one of the most closely watched GLP-1 lawsuits nationwide.
MDL 3163 – NAION Vision Loss (New Track)
- Filed: August 19, 2025
- Lead Cases: Henley v. Novo Nordisk, Prorock v. Novo Nordisk
- Injury Focus: NAION (non-arteritic anterior ischemic optic neuropathy)
- Impact: Permanent, irreversible vision loss
- Treatment Outlook: No effective treatment currently available
MDL 3163 marks a major expansion in GLP-1 litigation, targeting Ozempic, Wegovy, and similar drugs for their link to catastrophic vision damage. This track remains in its earliest stage — meaning first-mover advantages exist for law firms looking to build inventory and establish competitive positioning before broader national marketing drives saturation.
Why GLP-1 Litigation Stands Apart
1. Unprecedented Growth Trajectory
From August 2023 to 2,600+ active Ozempic lawsuits in just 24 months, this is one of the fastest-growing pharmaceutical MDLs in recent memory.
2. Regulatory Validation Strengthens Plaintiffs
Global regulatory agencies have already issued warnings and confirmed risks tied to GLP-1 agonists. This validation creates a stronger foundation for causation arguments compared to typical pharmaceutical claims.
3. Cultural Phenomenon Driving Plaintiff Pools
From celebrity endorsements to widespread off-label prescribing, GLP-1 drugs have entered mainstream culture, massively expanding the plaintiff base beyond traditional diabetes patients.
4. Dual Settlement Tiers Emerging
- Digestive Injuries (MDL 3094): Substantial claims but generally treatable conditions.
- Permanent Blindness (MDL 3163): Catastrophic damages potential with seven-figure upside per case.
The Timing Window for Law Firms
The current environment represents a rare strategic entry point for firms looking to lead in GLP-1 lawsuits:
- Cultural Peak: Litigation is developing while Ozempic and similar drugs dominate the weight-loss market.
- Early Stage Opportunity: The vision loss MDL was filed only weeks ago, making inventory-building efforts less competitive right now.
- Precedent Setting: The 2026 bellwether trials in MDL 3094 will likely define settlement frameworks across both tracks — firms with early positioning could see stronger leverage downstream.
Manufacturer’s Position
Novo Nordisk maintains that Ozempic is safe when used as prescribed, but plaintiffs allege the company failed to disclose severe risks, particularly as prescriptions exploded among non-diabetic consumers seeking rapid weight loss.
With cases mounting and regulatory scrutiny intensifying, manufacturers are under growing pressure to defend their flagship products in an environment where consumer awareness — and litigation — are surging.
Why This Matters for Your Firm
This litigation is a rare convergence of factors:
- Massive and rapidly growing plaintiff volume
- Scientific validation from regulators bolstering causation
- Two separate MDLs, allowing firms to diversify across treatable injury claims and catastrophic damages cases
For law firms exploring Ozempic lawsuits or looking to expand into emerging mass tort markets, the dual GLP-1 MDL structure offers a significant opportunity to get ahead of the curve.
