While the market fixates on the ongoing legal drama surrounding Avadel Pharmaceuticals, something extraordinary is unfolding within the company's commercial operations. Beneath the surface of legal battles, Avadel is quietly engineering a potential revolution in the narcolepsy treatment landscape, and the data suggests they may be succeeding beyond even the most optimistic expectations.

Avadel's story is one of tenacity. The company spent nearly a decade developing LUMRYZ, its once-at-bedtime oxybate formulation for narcolepsy. It faced significant regulatory hurdles and a crowded market dominated by Jazz Pharmaceuticals, the incumbent player. Yet, Avadel persevered, achieving FDA approval and launching LUMRYZ within a month – a remarkable feat in the pharmaceutical industry.

Now, less than a year into its commercial launch, LUMRYZ is demonstrating an impressive uptake that hints at a significant shift in the narcolepsy treatment paradigm. While the initial focus was understandably on converting patients from existing twice-nightly oxybate therapies, Avadel is attracting a growing number of patients who had previously discontinued oxybate treatment and, crucially, oxybate-naive patients. This suggests that LUMRYZ is not simply capturing existing market share but expanding the total market for oxybate therapy itself.

Let's delve into the numbers. Over 2,800 patients have enrolled in Avadel's RYZUP patient support services program, and over 1,700 have initiated LUMRYZ therapy. These figures represent significant quarter-over-quarter growth, but what's particularly striking is the accelerating pace of patient additions. If we analyze RYZUP additions over the past three quarters, we see a consistent increase of approximately 100 new patients per quarter. This accelerating growth, coupled with strong conversion rates and discontinuation rates well below the industry benchmark, suggests that Avadel is tapping into a previously underserved segment of the narcolepsy population.

"**Quote from Richard Kim, Chief Commercial Officer, during the Q1 2024 Earnings Call:** "Since launch last June, we continue to build strong and steady positive demand for LUMRYZ. Looking more closely at the patient segment dynamics...we are seeing -- beginning to see a more balanced ratio with roughly 50% coming from switches and the other 50% from discontinued and naive patients. Another differentiator from last quarter is that we're seeing a growing number of naive patients on therapy, which signals that LUMRYZ's value proposition is compelling to patients who have not previously been on an oxybate.""

RYZUP Enrollment Growth

The chart below depicts the accelerating growth in RYZUP enrollments over the past three quarters.

The potential of this trend is amplified by the fact that the diagnosed and treated narcolepsy population represents a small fraction of the estimated total patient population. This means that Avadel's success in attracting new and returning oxybate patients could be just the tip of the iceberg. Imagine a scenario where LUMRYZ's user-friendly once-at-bedtime dosing, coupled with targeted patient education campaigns and robust payer coverage, unlocks access to oxybate therapy for a significant portion of this untapped patient pool.

This possibility is not lost on Avadel. The company is actively pursuing expanded indications for LUMRYZ in pediatric narcolepsy and idiopathic hypersomnia (IH), conditions where the once-at-bedtime dosing could be particularly transformative.

Consider the pediatric narcolepsy population. While representing only around 5% of currently treated oxybate patients, the potential for LUMRYZ to alleviate the burden of twice-nightly dosing on children and their families is undeniable. The FDA's acceptance of Avadel's supplemental New Drug Application with a target action date of September 7th highlights the potential for this indication to drive significant growth in the latter half of 2024 and beyond.

Similarly, IH presents a compelling opportunity for LUMRYZ. The debilitating deep sleep inertia associated with IH makes waking up for a second dose of traditional oxybate therapies extremely challenging. A once-at-bedtime option like LUMRYZ could be a game-changer for these patients, potentially driving both market expansion and capturing share from existing therapies. With a pivotal Phase 3 trial for IH slated to begin in the second half of this year, the potential for further upside for LUMRYZ is substantial.

While legal battles may dominate the headlines, Avadel is quietly laying the groundwork for a potential narcolepsy empire. The company's early success in expanding the oxybate market, its relentless pursuit of new indications, and its accelerating patient acquisition paint a picture of a company poised for significant growth. As the dust settles on the legal front, the market may finally recognize the quiet revolution that Avadel has been building – one that could reshape the narcolepsy treatment landscape for years to come.

"**Fun Fact:** Did you know that narcolepsy affects approximately 1 in 2,000 people, and it can take up to 10 years for a person to be properly diagnosed? Avadel's commitment to raising awareness about this debilitating condition and providing access to effective therapies like LUMRYZ could have a profound impact on the lives of thousands of patients."
