It’s a good day to be the pharmaceutical giant Eli Lilly.

This morning, the company unveiled its latest innovation in the weight-loss drug wars: the KwikPen. Per a press release, the KwikPen contains a month’s worth of Zepbound, Eli Lilly’s GLP-1 product to combat obesity, and it’s designed to make taking the medicine more convenient. Alongside the announcement of this innovation, Eli Lilly’s main competitor, Novo Nordisk, dropped the news that its experimental drug, CagriSema, performed worse for patient weight loss in a head-to-head trial against Eli Lilly’s proprietary drug, tirzepatide.

A November study from the health policy nonprofit KFF found that about 1 in 8 American adults were using a GLP-1 for weight loss or to treat a chronic condition. And as the weight-loss drug market soars, its two most dominant players—Eli Lilly and Novo Nordisk, the maker of Ozempic—are battling it out to offer the most convenient, most effective, and least expensive iterations of their respective drugs. 

Right now, Eli Lilly appears to be the leader in the GLP-1 race amid multiple difficult headwinds for Novo Nordisk. As of this writing, Novo Nordisk stock is down nearly 16% since market open, while Eli Lilly is up by nearly 5%.

Weight-loss drugs take new, more convenient forms

Over the past several months, both Eli Lilly and Novo Nordisk have invested in novel drug formats to retain customers and reach new audiences. 

Back in December, Novo Nordisk received FDA approval for a first-of-its-kind, once-daily pill for weight loss. The pill, which is an oral form of Novo Nordisk’s GLP-1 Wegovy, offers a less invasive way for users to administer weight-loss drugs, which are typically delivered via an injector. Eli Lilly is currently in the testing phases of its own oral GLP-1, but it does not yet offer anything similar to the Wegovy pill. 

In the meantime, the KwikPen will presumably make taking Zepbound a bit easier for Eli Lilly’s customer base. Currently, patients use a separate auto-injector for each of their weekly doses of the drug. Each KwikPen, by contrast, comes preloaded with four doses, meaning one pen lasts for a full month. It’s available in six strengths, ranging from 2.5 milligrams to 15 milligrams. For cash-paying patients, the KwikPen will be available via Eli Lilly’s direct-to-consumer website, LillyDirect.
