Pharming Group reports financial results for the first quarter of 2023

• FDA approval and commercial launch of Joenja® (leniolisib) in the U.S.
• Joenja® launch off to strong start with 23 U.S. patients on paid therapy
• Revenues decreased by 9% to US$42.5 million, compared to the first quarter of 2022, primarily due to temporary reimbursement disruptions for some patients on government insurance programs. This issue, affecting all of the HAE market, has since resolved
• Continue to anticipate low single digit growth in annual revenues from RUCONEST® in 2023
• Continued significant investments made in leniolisib launch preparations and organizational structure
• Overall cash balance of US$184.8 million at the end of the quarter

LEIDEN, Netherlands, May 11, 2023 /PRNewswire/ -- Pharming Group N.V. (“Pharming” or “the Company”) (Euronext: PHARM/Nasdaq: PHAR) presents its preliminary, unaudited financial report for the first quarter ended March 31, 2023.

Chief Executive Officer, Sijmen de Vries commented:

“In the first quarter of 2023, we reached an important milestone with the approval and launch of Joenja® (leniolisib), the first and only approved treatment for patients with APDS in the United States. With this approval, U.S.-based patients living with APDS now have access to the medication to normalize their underlying immune function, and Pharming is one step closer to its goal of becoming a leading global rare disease company dedicated to patient communities with unmet medical needs.

The launch of Joenja® is off to a strong start. In April, we announced that the first commercial product had been shipped to patients with payor reimbursement and we can confirm that we now have 23 patients on paid therapy.

Turning to RUCONEST®, as we guided on our 2022 full year results call on March 16, we continue to anticipate low single digit revenue growth with quarterly fluctuations. In the first quarter, there were a number of fluctuations that impacted RUCONEST® revenues and the HAE market across acute and prophylactic products. These factors were mainly due to disruptions in reimbursement for some patients on government insurance programs, which delayed shipments.

These impacts to the business have since resolved and we can confirm that we have seen a recovery and catch up in revenues. Additionally, we are observing strong underlying in-market demand for RUCONEST® and have a high number of new patient enrollments in the U.S. as we entered the second quarter of this year.

Looking ahead, we continue to progress leniolisib through regulatory pathways in Europe, the U.K. and Japan and expect a positive opinion from the European regulator in the second half of 2023, with Europe and U.K. approvals following approximately two months later.

We also began the first of two pediatric clinical trials for children with APDS, whom we believe account for some 25% of U.S.-based APDS patients. The first trial for ages 4 to 11 began in February with the second, for children ages 1 to 6, to follow in the third quarter of this year. These pediatric trials, as well as the development of further leniolisib indications, will add to Pharming’s pipeline.

Finally, with a focus on rare disease assets, we are continuously investigating in-licensing and acquisition opportunities which can further enhance our portfolio.”

First Quarter and subsequent highlights

Commercialized assets

U.S. FDA Approval of Joenja® (leniolisib) – the first and only treatment approved for APDS

On March 24, 2023, Pharming announced that the US Food and Drug Administration (FDA) approved Joenja® (leniolisib) for the treatment of activated phosphoinositide 3-kinase delta (PI3Kδ) syndrome (APDS) in adult and pediatric patients 12 years of age and older. Joenja®, an oral, selective PI3Kδ inhibitor, is the first and only treatment approved in the U.S. for APDS. The FDA evaluated the New Drug Application (NDA) for Joenja® under priority review and approved the drug based on findings from a multinational, triple-blind, placebo-controlled, randomized Phase II/III clinical trial.

With the approval of Joenja®, as a treatment for primary immunodeficiency, the FDA granted Pharming a priority review voucher (“PRV”). Pursuant to the terms of Pharming’s 2019 exclusive license agreement with Novartis for leniolisib, Novartis has the right to purchase the PRV from Pharming for a small minority share of the value of the PRV. Pursuant to the agreement with Novartis, the first commercial sale of Joenja® in the second quarter of 2023 triggered a US$10 million milestone payment by Pharming to Novartis and the regulatory approval for APDS triggered a US$0.5 million milestone payment by Pharming to another party in the first quarter of 2023. Pharming is obligated to make certain additional milestone payments to Novartis totaling up to US$190 million upon the achievement of leniolisib sales milestones and tiered royalty payments to Novartis calculated as low-teen to high-teen percentages of leniolisib net sales.

Additional information on the PRV, as well as milestone and royalty payments can be found in our 2022 Annual Report or in the Form 20-F filed with the SEC.

Joenja® U.S. Commercial Launch

Based on available literature, Pharming estimates that over 1,500 patients are affected by APDS in the U.S., Europe, U.K., Japan, Canada and Australia. Pharming has already identified over 500 of these patients, of which approximately 200 are U.S.-based. Of that, approximately 75% are U.S.-based patients over the age of 12 and are currently eligible for treatment with Joenja®.

The first commercial shipments of Joenja® to APDS patient in the U.S., with payor reimbursements, were delivered approximately two weeks following FDA approval. Since launching in early April, Joenja® has 23 patients on paid therapy. We have received enrollments from significantly more patients who are in the process of payor reimbursement authorizations which have been proceeding as expected. The first sales of Joenja® will be booked and reported in the second quarter of 2023.

We anticipate providing updates on our commercial outlook for Joenja® in the second half of 2023.

RUCONEST® marketed for the treatment of acute HAE attacks

In the first quarter of 2023, RUCONEST® revenues were US$42.5 million, a 9% decline compared to the same quarter last year.

The decrease in overall revenues were primarily due to temporary disruptions in reimbursement for some patients on government insurance programs, which impacted the overall HAE market across all acute and prophylactic products. As a result, shipments to these patients were delayed and impacted February sales in particular. The HAE market disruptions seen in the first quarter have since resolved and we have seen a recovery in sales.

We are therefore maintaining our full-year outlook for low single digit growth in RUCONEST® revenues for 2023.

Underlying in-market demand for RUCONEST® continued to be strong, including a high number of new patient enrollments in the first quarter.

Strategic Highlights - regulatory and clinical updates

Leniolisib for APDS

Pharming made significant progress in the quarter towards our objective of obtaining regulatory approvals for leniolisib for APDS in additional key markets and for pediatric patients, and to identify additional indications for development of leniolisib beyond APDS.

EEA and U.K. market

In February 2023, Pharming announced that the European Medicines Agency’s (EMA) Committee for Human Medicinal Products (CHMP) decided to shift its assessment of the Marketing Authorisation Application (MAA) for leniolisib to a standard review timetable. The list of questions received by Pharming from EMA included a request to submit updated data from the ongoing long-term extension study collected after the interim analysis included in the original MAA. As previously announced, we anticipate responding to the CHMP’s list of questions in May 2023 and expect that the CHMP will issue its opinion on the leniolisib MAA in the second half of 2023. We anticipate that European marketing authorisation will follow approximately two months later.

In the U.K., and in line with the European Commission Decision Reliance Procedure (ECDRP), we intend to file the leniolisib dossier to the U.K.'s Medicines and Healthcare products Regulatory Agency (MHRA) within five days of a positive CHMP opinion; expected in the second half of 2023.

Japan

On March 9, 2023, we filed an Orphan Drug Designation (ODD) application with the Ministry of Health, Labor and Welfare (MHLW) in Japan. We expect to begin a clinical trial in Japan in second quarter of 2023 for APDS patients aged 12 and older. We currently anticipate marketing leniolisib in Japan directly following regulatory approval.

Pediatric clinical trial

In February 2023, as part of Pharming’s Pediatric Investigational Plan (PIP), the Company announced that the first patient had been enrolled in its Phase III clinical trial evaluating the investigational drug leniolisib in children with APDS, at sites in the United States, Europe, and Japan. The single-arm, open-label, multinational clinical trial will evaluate the safety, tolerability, and efficacy of leniolisib in approximately 15 children aged 4 to 11 years who have a confirmed APDS diagnosis.

The second pediatric clinical trial for patients 1 to 6 years of age is scheduled to commence in the third quarter of 2023 and is also part of the PIP for leniolisib as a treatment for APDS in children.

Leniolisib for additional indications (PI3Kδ platform)

As announced in our Joenja® approval conference call on March 27, we have commenced working towards prioritizing other indications where leniolisib has the potential to deliver value for patients. PI3Kδ has been identified as an important factor in a variety of disease states, and leniolisib has demonstrated an attractive, long-term efficacy, safety and tolerability profile in clinical trials conducted in both healthy volunteers and patients. This provides a solid basis for our plans for the investigation and investment in further leniolisib indications. We are exploring further indications and will update the market later on this year.

Pre-Clinical Pipeline

OTL-105

We anticipate providing further updates as we move towards preparing an Investigational New Drug (IND) filing. If the data from pre-clinical HAE animal studies meet scientific requirements, then we expect to start IND-enabling pre-clinical studies in 2023.

Pompe

Based on our preclinical investigations and evaluations for potential differentiating features of the product candidate, it has been decided that the further development of this asset will be discontinued.

Other events during the quarter

On March 12 and 13, 2023, Pharming issued three press releases regarding the events surrounding Silicon Valley Bank. Pharming confirms that it has full access to its deposits.

Financial summary

Financial highlights

Total revenues for the first quarter of 2023 decreased by 9% to US$42.5 million compared to US$46.6 million in the first quarter of 2022. The decrease in overall revenues were primarily due to temporary disruptions in reimbursement for some government patients, which impacted the overall HAE market across all acute and prophylactic products and have since resolved. As a result, shipments to these patients were delayed and impacted February sales in particular. Underlying in-market demand for RUCONEST® however continued to be strong.

Gross profit decreased by 8% to US$38.5 million (1Q 2022: US$41.7 million), mainly due to the decrease in revenues.

Operating profit decreased to a loss of US$13.7 million versus an operating profit of US$2.8 million in the first quarter of 2022. This was mainly due to an expected increase in operating expenses from US$39.8 million in the first quarter of 2022 to US$52.7 million in the first quarter of this year. This increase was caused by a combination of launch preparation for leniolisib and increased payroll expenses due to business growth.

The Company had a net loss of US$12.2 million, versus a net profit of US$3.5 million in the first quarter of 2022. This was mainly due to the decrease in operating profit and more favorable currency exchange rate results in the first quarter of 2022 versus the first quarter of this year.

Negative cash flows from operations amounted to US$22.8 million in the first quarter of 2023. Cash and cash equivalents decreased by US$22.5 million to US$184.8 million from US$207.3 million at the end of the fourth quarter of 2022.

Outlook

For 2023, the Company anticipates:

• Continued low, single digit growth in annual revenues from RUCONEST®. Quarterly fluctuations are expected.
• Following FDA approval, we are commercializing Joenja® (leniolisib) in the U.S. commencing early April 2023.
• We anticipate a positive CHMP opinion for leniolisib in 2H 2023, Marketing Authorisation in Europe expected ~2 months later, followed by commercial launches in individual EU countries
• Following an anticipated positive CHMP opinion in 2H 2023, we intend to submit an ECDRP filing for leniolisib with the U.K. MHRA shortly thereafter. Approval expected several months later.
• Pharming will continue to allocate resources to accelerate future growth. Investments in launch preparations, commercialization and focused clinical developments for leniolisib including to support pediatric and Japanese approvals, as well as for the development of leniolisib in additional indications, will continue to impact profit throughout 2023. Our current cash on hand, including the continued cash flow of RUCONEST® are expected to be sufficient to fund these investments.
• Further details on our plans to develop leniolisib in additional indications to be provided in 2H 2023.
• Investments and continued focus on potential acquisitions and in-licensing of mid to late stage opportunities in rare diseases. Financing, if required, would come via a combination of our strong balance sheet and access to capital markets.

No further specific financial guidance for 2023 is provided.
