Financial results

Net revenue of CHF 26 million in the first half of 2024 is the result of QUVIVIQ product sales and contract revenue recognized in connection with Owkin (CHF 3 million). This compares to CHF 51 million in the first half of 2023, which included CHF 32 million sales of PIVLAZ in Japan (assigned in the meantime to Nxera Pharma as part of a transaction, more details can be found in the dedicated press release) and CHF 2 million revenue share from Johnson & Johnson related to ponesimod sales (revenue-sharing agreement now eliminated as part of the reacquisition of aprocitentan, more details can be found in the dedicated press release).

US GAAP operating expenses in the first half of 2024 benefited from extraordinary income of CHF 125 million from the Viatris deal resulting in an expense of CHF 94 million (CHF 426 million in the first half of 2023), of which CHF 4 million related to cost of sales (CHF 5 million in the first half of 2023), CHF 71 million to R&D expenses (CHF 172 million in the first half of 2023), and CHF 142 million to SG&A expenses (CHF 249 million in the first half of 2023).

US GAAP net loss in the first half of 2024 amounted to CHF 79 million (CHF 405 million net loss in the first half of 2023). The decrease of the net loss is mainly attributable to the one-off income related to the Viatris deal but was also driven by lower operating expenses throughout all functions.

The US GAAP net income resulted in a basic net loss per share of CHF 0.44 (basic and diluted) in the first half of 2024, compared to a net loss per share of CHF 2.28 (basic and diluted) in the first half of 2023.

* Idorsia measures, reports, and issues guidance on non-GAAP operating performance. Idorsia believes that these non-GAAP financial measurements more accurately reflect the underlying business performance and therefore provide useful supplementary information to investors. These non-GAAP measures are reported in addition to, not as a substitute for, US GAAP financial performance.

Non-GAAP net loss in the first half of 2024 amounted to CHF 183 million: the CHF 104 million difference versus US GAAP net income was mainly due to the one-off effect of the Viatris deal (CHF 125 million income), depreciation and amortization (CHF 8 million), and share-based compensation (CHF 10 million).

The non-GAAP net loss resulted in a net loss per share of CHF 1.02 (basic and diluted) in the first half of 2024, compared to a net loss per share of CHF 2.07 (basic and diluted) in the first half of 2023.

Viatris collaboration
In March 2024, Idorsia closed agreements with Viatris Inc. (NASDAQ: VTRS), a global healthcare company, for collaboration on the global development and commercialization of two Phase 3 assets – selatogrel and cenerimod – with Idorsia receiving an upfront payment of USD 350 million, and the right to potential development and regulatory milestone payments of up to USD 300 million, potential sales milestone payments of up to USD 2.1 billion, and potential contingent tiered royalties from mid-single- to low-double-digit percentage on annual net sales.

A joint development committee is overseeing the development of the ongoing Phase 3 programs for selatogrel and cenerimod up to regulatory approval. Idorsia will contribute up to USD 200 million in the next 3 years and transferred the dedicated personnel for both programs to Viatris.

Viatris has worldwide commercialization rights for both selatogrel and cenerimod (excluding, for cenerimod only, Japan, South Korea, and certain countries in the Asia-Pacific region). Idorsia has also granted Viatris a right of first refusal and first negotiation for certain other pipeline assets.

Convertible bonds 2024
In July 2018, the Group issued CHF 200 million of senior unsecured convertible bonds (ISIN: CH0426820350), which were due to mature on July 17, 2024. On May 6, 2024, a bondholder meeting was held, where 83.5% of the total outstanding bondholders voted in favor of amendments to the terms of the bonds. The approved bond terms include an amended conversion price of CHF 6.00, extended maturity date of January 17, 2025, and the option to call the bonds at par, in full or in part, at any time upon giving ten trading days' notice. On June 25, 2024, the higher cantonal composition authority (obere kantonale Nachlassbeh?rde) issued its written decision approving the amendments of the terms of the outstanding convertible bonds.

If no appeal is filed within the statutory period of 30 days, the amendments will be effective, and the company expects to transfer the consent fee of 8 million shares on September 5, 2024.

Financial outlook 2024 – upgraded
For 2024 – excluding unforeseen events – the company expects QUVIVIQ net sales of around CHF 55 million; SG&A expenses of around CHF 300 million; R&D expense of around CHF 145 million for Idorsia-led pipeline assets; non-GAAP operating expenses of up to CHF 455 million. This performance would result in a non-GAAP operating loss of around CHF 400 million (excluding contract revenues and the one-off benefit from the Viatris deal).

The company expects US GAAP operating loss for 2024 to reach CHF 320 million which includes a one-off benefit of CHF 125 million from the Viatris deal.

Arno Groenewoud, Chief Financial Officer, commented:
“We have tightly controlled our expenses in the first half enabling us to slightly reduce the R&D OPEX guidance, improving the overall outlook for 2024. The actions we’ve taken in the first half of 2024, namely the Viatris deal and the restructured convertible bond, have given us the time to ensure we have the optimal deal for aprocitentan.”

Liquidity and indebtedness
At the end of the first half of 2024, Idorsia’s liquidity amounted to CHF 237 million.

Commercial operations
In the first half of 2024, QUVIVIQ? (daridorexant) in the US, Germany, Italy, Switzerland, Spain, UK, Canada, Austria, and France generated total product sales of CHF 23.6 million.

United States

In the US, net sales of QUVIVIQ^? (daridorexant) in the first half of 2024 reached CHF 14.2 million, an increase of 61% versus the first half of 2023. This net sales number includes the QUVIVIQ copay program aimed at driving demand and product uptake, and thus does not reflect the actual number of prescriptions dispensed.

As of the end of the first half of 2024, more than 155,000 patients have been treated with QUVIVIQ since launch in the US, almost 450,000 prescriptions have been dispensed, and the product has been prescribed by more than 45,000 healthcare professionals.

Tosh Butt, President, and General Manager of Idorsia US, commented:
“Having optimized our resources and promotional effort, and adjusted our commercial approach towards a payer-paid model, setting a new baseline for sales in the US, I’m pleased that we have been able to maintain demand for QUVIVIQ. We continue to remain hopeful that our citizen petition requesting a review of the evidence can lead to the descheduling of the DORA class of chronic insomnia medications and the benefits of QUVIVIQ, both in efficacy and safety, will then be fully recognized.”

For more information about QUVIVIQ in the US, see the Full Prescribing Information (PI and Medication Guide).

On March 19, 2024, the US Food and Drug Administration (FDA) approved TRYVIO? (aprocitentan) for the treatment of hypertension in combination with other antihypertensive drugs, to lower blood pressure in adult patients who are not adequately controlled on other drugs. Lowering blood pressure reduces the risk of fatal and non-fatal cardiovascular events, primarily strokes and myocardial infarctions. The recommended dosage of TRYVIO is 12.5 mg orally once daily, with or without food.

Idorsia plans to make TRYVIO available in the fourth quarter of 2024 to the millions of patients in the US whose high blood pressure is not adequately controlled by other drugs.

Tosh Butt concluded:
“We are making progress with our preparation to make TRYVIO available before the end of this year. We’ve conducted thorough market research and the conversations with payers are going well. They have been intrigued by our innovation and understand that TRYVIO is addressing significant patient need as treated hypertensive patients who remain uncontrolled are at a higher risk of serious cardiovascular events. We are bringing the first innovation, a novel pathway and the first new mode of action for systemic hypertension in almost 40 years to the market. Around 90% of uncontrolled hypertensive patients have comorbidities, typically diabetes, obesity, dyslipidemia, CKD and other cardiovascular comorbidities, and they are often taking three, four, or more medicines. For TRYVIO, it’s a once-daily tablet, and there's no need to adjust the dose, so it’s easy for patients to use and easy for physicians to prescribe.”

Further details on the approval, together with commentary from company management can be found in the dedicated press release and investor webcast available from the company corporate website.

For more information see the Full Prescribing Information including BOXED Warning (PI and Medication Guide).

Europe and Canada

QUVIVIQ (daridorexant) net sales in the first half of 2024 reached CHF 9.4 million in the EUCAN region.

Benjamin Limal, President of Europe and Canada region, commented:
“Following the expansion into new markets and increased access secured in 2023 and early 2024, both net sales and demand in the Europe and Canada region are accelerating. This is particularly driven by a great performance in Germany and an outstanding launch in France, where we are starting to see the need for an effective and safe insomnia treatment translating into demand. It’s still early days in many countries, but I am confident this dynamic will continue in the coming months as we expand access in key European markets.”

For more information about QUVIVIQ in Switzerland, see the Patient Information and Information for Healthcare Professionals. For more information on the marketing authorization of QUVIVIQ in Canada, see the Product Monograph.

On June 27, 2024, the European Commission (EC) approved JERAYGO? (aprocitentan) for the treatment of resistant hypertension in adult patients in combination with at least three antihypertensive medicinal products. The recommended dose is 12.5 mg orally once daily. The dose can be increased to 25 mg once daily for patients tolerating the 12.5 mg dose and in need of tighter blood pressure (BP) control.

Idorsia continues to carefully evaluate all funding options including potential collaborations for the commercialization of aprocitentan for the millions of patients in the EU whose high blood pressure is not adequately controlled by other drugs.

Further details on the approval, together with commentary from company management can be found in the dedicated press release available from the company corporate website.

Idorsia-led portfolio

Daridorexant
Daridorexant is a dual orexin receptor antagonist (DORA) which blocks the binding of the wake-promoting orexin neuropeptides. Rather than inducing sleep through broad inhibition of brain activity, daridorexant only blocks the activation of orexin receptors. Daridorexant is commercially available as QUVIVIQ in the US, Germany, Italy, Switzerland, Spain, the UK, Canada, Austria, and France, and is approved throughout the EU (see “Commercial operations” above).

A Phase 4 study to investigate the efficacy of daridorexant in patients with insomnia and comorbid nocturia (NCT05597020) has finished with daridorexant at a daily dose of 50 mg delivering positive topline results. The study results are being fully analyzed, and details will be made available at upcoming scientific congresses and in peer-reviewed publications.

Idorsia is conducting a Phase 2 dose-finding study to assess the efficacy, safety, and pharmacokinetics of multiple-dose oral administration of daridorexant in pediatric patients aged 10 to <18 years with insomnia disorder (NCT05423717). The primary objective of the study is to characterize the dose-response relationship of daridorexant on objective total sleep time (TST), using polysomnography. The study is expected to enroll around 150 patients, who will be randomized in a 1:1:1:1 ratio to 10 mg, 25 mg, or 50 mg daridorexant, or placebo. The study is part of a US FDA-approved Pediatric Study Plan and an EU PDCO-approved Paediatric Investigation Plan.

Aprocitentan
Aprocitentan is a once-daily, orally active, dual endothelin receptor antagonist, which inhibits the binding of ET-1 to ET_A and ET_B receptors. Aprocitentan has a low potential for drug-drug interaction and a mechanism of action suited for lowering blood pressure in adult patients whose hypertension is not adequately controlled by other drugs. Aprocitentan is approved in the US under the tradename TRYVIO? where it will be made available later in 2024, and in Europe under the tradename JERAYGO? (see “Commercial operations” above). Marketing authorization applications for the UK, Canada, and Switzerland are in preparation.

Lucerastat
Lucerastat is an oral inhibitor of glucosylceramide synthase, offering a potential new treatment approach for all patients living with Fabry disease, irrespective of the mutation type of the GLA gene. In October 2021, the company reported that lucerastat 1000 mg b.i.d. did not meet the primary endpoint of reducing neuropathic pain during 6 months of treatment versus placebo. However, Lucerastat demonstrated a substantial reduction in levels of the Fabry disease biomarker plasma Gb3 during the treatment period, with a decrease of approximately 50% observed in plasma Gb3 in the lucerastat treatment group compared to an increase of 12% in the placebo group. Furthermore, results suggested a treatment effect on kidney function. Lucerastat was well tolerated. Analysis of the ongoing open-label extension (OLE) of the Phase 3 study corroborated the long-term effect on plasma Gb3 levels and a potential positive long-term effect on kidney function. The analysis also showed a safety and tolerability profile consistent with that observed during the 6-month randomized treatment period. The company is conducting a kidney biopsy substudy within a subset of patients currently participating in the OLE study in order to steer further development in Fabry disease. In parallel, Idorsia is working with regulatory authorities to design the next Phase 3 study to evaluate the effect of lucerastat on renal function.

IDOR-1134-2831
IDOR-1134-2831 is Idorsia’s synthetic glycan vaccine targeting Clostridium difficile infection (CDI). The first study in the Phase 1 clinical pharmacology program has enrolled its first healthy participants to assess the safety, tolerability, and immunogenicity of up to 3 ascending dose levels of the IDOR-1134-2831 vaccine.
