Protagonist believes its oral IL-23 blocker will not just compete with existing injectables but will capture a new market. They target the over 50% of eligible patients who currently take no therapy due to a dislike of injections or the safety profiles of other oral options, thereby expanding the total addressable market.

Lilly’s next-generation obesity drug shows unprecedented weight loss but with a harsher side effect profile. This suggests a market segmentation strategy targeting the most severely obese patients, rather than competing directly with existing therapies for the broader population. The market is evolving beyond a simple race for maximum efficacy.
Breakthrough drugs aren't always driven by novel biological targets. Major successes like Humira or GLP-1s often succeeded through a superior modality (a humanized antibody) or a contrarian bet on a market (obesity). This shows that business and technical execution can be more critical than being the first to discover a biological mechanism.
The GLP-1 drug revolution is moving beyond weekly injections for wealthy markets. Upcoming pill-form versions will eliminate the need for refrigerated supply chains, opening up distribution in developing countries. Combined with expiring patents, this focus on form factor and cost will enable mass global adoption.
The emerging Amylin class of obesity drugs shows a consistently more favorable side effect profile than GLP-1 agonists. While weight loss efficacy may be comparable, the superior tolerability positions Amylin as a strong future competitor, either as a standalone option for sensitive patients or as a backbone for combination therapies.
The obesity drug market is moving past the "weight loss Olympics." While high efficacy is the entry ticket, new differentiators are emerging. Companies like Wave Life Sciences are focusing on muscle-sparing properties, while Structure is advancing oral GLP-1s. This indicates a maturing market where patient convenience, quality of weight loss, and long-term maintenance are becoming key value drivers.
Acknowledging its late entry into the crowded obesity market, Protagonist consulted key opinion leaders to define the ideal drug profile: an oral "triple G" agonist. By using its peptide platform to build exactly what experts requested, the company aims to leapfrog competitors with a best-in-class product rather than an incremental improvement.
Novo priced the maintenance dose of its oral Wegovy pill far lower than anticipated. This aggressive strategy, costing less than the average U.S. monthly grocery bill (~$400), is a direct attempt to regain momentum from rival Eli Lilly and expand the self-pay market before more oral competitors launch.
Despite significant progress in managing symptoms for autoimmune conditions, very few treatments fundamentally alter the disease's course. The major unmet needs and investment opportunities lie in therapies that can induce remission or target common underlying pathologies like fibrosis, moving beyond mere symptom relief.
Despite being a pill, oral Wegovy requires an empty stomach, only 4oz of water, and a 30-minute post-dose fast. This difficult regimen is a major impediment to its uptake, particularly in the U.S. where patients prioritize the maximum efficacy of injectables over the supposed convenience of a cumbersome pill.
A key part of Eli Lilly's R&D strategy is tackling large-scale health problems that currently have no treatments and therefore represent a 'zero-dollar market.' This blue-ocean strategy contrasts with competitors who focus on areas with established payment pathways.
