Pfizer’s (PFE) move to acquire Metsera (Monday, Sept. 22, 2025) for up to $4.9 billion marks a pivotal expansion in the fast-evolving obesity and diabetes treatment market, intensifying the industry’s GLP-1 rivalry among major pharmaceutical players. Modular Medical (NASDAQ: MODD), with its latest progress in pump-based GLP-1 delivery, and Eli Lilly (LLY), whose oral GLP-1 pipeline is attracting both clinical and investor attention, are making strategic advances that could reshape patient care across metabolic disorders.

Pfizer’s Strategic Entry Into Obesity Therapies

Pfizer’s acquisition of Metsera (MSTR), priced at a 43% premium, grants the company four clinical-stage GLP-1 and amylin candidates—including injectable and oral therapies promising less frequent dosing, notably monthly injections that could disrupt the current weekly regimen standard. The deal underscores Pfizer’s recovery strategy after setbacks in its internal GLP-1 research, positioning it closer to sector leaders Novo Nordisk and Eli Lilly, while signaling heightened competition for investor capital and R&D focus.

Modular Medical’s GLP-1 Pump Platform: A Next-Gen Solution

San Diego-based Modular Medical (MODD) recently released compelling preclinical data demonstrating its pump-based, rapid-acting GLP-1 therapy achieved up to 17.1% weight loss in 28 days with superior glucose control compared to semaglutide in animal models. The company’s MODD1 patch pump, already FDA-cleared for insulin delivery, is being readied for human evaluation in obesity and diabetes. Unlike weekly GLP-1 injections, MODD’s device leverages basal-bolus dosing, allowing for more gradual weight loss and flexible, personalized titration—potentially improving tolerability for patients who struggle with longer-acting agents.

Modular Medical’s platform, designed by the inventor of Tandem Diabetes’ (TNDM) t:slim pump, targets the underserved “almost-pumpers” adult population who require less complex, cost-effective therapy for glycemic and weight control. The company’s clinical ambitions put it on the map to challenge both incumbent and emerging GLP-1 technologies.

Eli Lilly’s Oral GLP-1 Leadership and Competitive Updates

Eli Lilly’s (LLY) orforglipron, a once-daily oral GLP-1 candidate, is generating promising trial results: it outperformed Novo Nordisk’s oral semaglutide (Rybelsus) for both weight loss and glucose control in patients with diabetes. Clinical data shows orforglipron delivered around 12% weight loss in overweight adults, with dosing flexibility that doesn’t require fasting—a practical improvement over competitors. As Lilly ramps up production to meet surging demand and eyes speedy regulatory pathways, analysts note its strong positioning versus Novo Nordisk despite sector price volatility and intensified competition.

The Road Ahead: GLP-1 Innovation and Patient Impact

The surge in next-generation GLP-1 therapies—from monthly injections to pump-based and oral platforms—reflects a renewed commitment by both legacy and emerging players to address the global obesity and diabetes epidemic with more accessible, patient-friendly options. As Pfizer, Modular Medical, and Eli Lilly accelerate their clinical programs, regulatory milestones and real-world data will likely reshape the landscape for metabolic treatment—and redefine what is possible for patients seeking safe, effective, and convenient therapies.
