Lastly, and most importantly, the FDA approved OJEMBA™ (tovorafenib), Day One Biopharmaceuticals’ type II RAF inhibitor for patients with relapsed or refractory pLGG harboring a BRAF fusion or rearrangement or BRAF V600 mutation, ushering in an important new treatment for children living with relapsed or refractory pLGG.” Key First Quarter Events PartnerEventTalpheraXOMA added another commercial asset to its royalty portfolio with an economic interest in DSUVIA®, which is marketed by Alora Pharmaceuticals. XOMA receives 100 percent of the DSUVIA® economics until a threshold is achieved; thereafter, XOMA retains the 15 percent royalty associated with DSUVIA® commercial sales. The 75 percent royalties from Department of Defense purchases and remaining milestone payments will be shared equally between XOMA and Talphera.Kinnate PharmaceuticalsXOMA initiated the acquisition of Kinnate Pharmaceuticals for $2.5879 in cash per share, plus a non-tradeable contingent value right (CVR) representing the right to receive 85 percent of the net proceeds from the out license or sale of Kinnate assets effected on or before April 2, 2025, and 100% of the net proceeds received from Pierre-Fabre.Zevra TherapeuticsU.S. Food and Drug Administration (FDA) accepted the arimoclomol NDA resubmission for review and set a Prescription Drug User Fee Act (PDUFA) action date of September 21, 2024.

Anticipated 2024 Events of Note PartnerEventZevra TherapeuticsSeptember 21, 2024 – FDA PDUFA action date for arimoclomol NDATakedaIn its press release dated March 13, 2024, Takeda announced plans to initiate a global Phase 3 trial of mezagitamab in ITP in fiscal year 2024.ii First Quarter 2024 Financial Results XOMA recorded total revenues of $1.5 million for the first quarter of 2024, which included a $1.0 million milestone payment received from AVEO Oncology, as compared with $0.4 million in the first quarter of 2023. Research and development (R&D) expenses were $33,000 and $54,000, respectively, for the first quarters of 2024 and 2023. Upon closing the Kinnate merger in the second quarter of 2024, XOMA assumed operations of Kinnate’s pipeline, as well as ongoing Phase 1 study, and will incur increased R&D costs until winddown activities are complete. General and administrative (“G&A”) expenses were $8.5 million for the first quarter of 2024, compared to $6.2 million for the first quarter of 2023. The increase of $2.3 million was primarily due to a $1.3 million increase in stock-based compensation and a $0.7 million increase in consulting and legal expenses. The increase in stock-based compensation expenses was largely due to the appointment of Mr. Hughes as our full-time Chief Executive Officer in January 2024. In the first quarter of 2024, G&A expenses included $2.9 million in non-cash stock-based compensation expense, compared with $1.6 million in the first quarter of 2023. The increase in stock-based compensation expenses was largely due to the PSU grant associated with the appointment of Mr. Hughes as our full-time Chief Executive Officer in January 2024 combined with PSUs granted in May 2023. Interest expense in the first quarter of 2024 was $3.6 million, representing interest related to the Blue Owl Loan established in December 2023. The Company reported total other income, net, of $2.0 million in the first quarter of 2024, as compared to total other income, net, of $0.4 million in the corresponding period of 2023. The $1.6 million increase reflects a $1.3 million increase in investment income due to higher cash balances and higher market interest rates on our investments, as well as the change in the market price of Rezolute’s common stock. Net loss for the first quarter of 2024 was $8.6 million, compared to a net loss of $9.8 million for the first quarter of 2023. On March 31, 2024, XOMA had cash and cash equivalents of $142.4 million (including $6.2 million in restricted cash). On December 31, 2023, XOMA had cash and cash equivalents of $159.6 million (including $6.3 million in restricted cash). During the first quarter of 2024, XOMA received $9.8 million in cash from royalty and milestone payments and deployed $8 million to acquire new royalty and milestone economic interests. Net cash used in operating activities during the quarter was $4.9 million. On April 15, 2024, the Company paid a total of $1.4 million in cash dividends on the 8.625% Series A Cumulative Perpetual Preferred Stock (Nasdaq: XOMAP) and the 8.375% Series B Cumulative Perpetual Preferred Stock (Nasdaq: XOMAO).

Full commercial launch of OLPRUVA at the end of January 2024, with market access growing to ~75% of covered lives as of May 1, 2024 Arimoclomol NDA review underway with PDUFA date of September 21, 2024 Reported positive topline results from KP1077 Phase 2 Trial in idiopathic hypersomnia, with full data to be presented at SLEEP 2024 in early June 2024 Conference call scheduled for today, May 8, 2024, at 8:00 a.m. ET CELEBRATION, Fla., May 08, 2024 (GLOBE NEWSWIRE) -- Zevra Therapeutics, Inc. (NasdaqGS: ZVRA) (Zevra, or the Company), a rare disease therapeutics company, today provided corporate updates and reported its financial results for the first quarter ended March 31, 2024. “During the first quarter, we made steady progress in executing on our strategic objectives: to successfully launch OLPRUVA and ensure access for patients, to prepare for the potential launch of arimoclomol, and to advance the KP1077 program in sleep disorders,” said Neil F. McFarlane, President and Chief Executive Officer of Zevra. “Our recent debt refinancing allowed us to simplify our capital structure while providing additional flexibility to support our strategic priorities,” said R. LaDuane Clifton, Zevra’s Chief Financial Officer, Secretary and Treasurer. “With a solid balance sheet, we are focused on creating long-term value for shareholders by executing against our plan of becoming a leading rare disease company.” Recent Business and Corporate Highlights: OLPRUVA The full commercial launch of OLPRUVA was initiated at the end of January 2024, and the team has engaged with more than 90% of the specialists at the 40 centers of excellence that treat people with UCD. During the quarter, Zevra had four new patient enrollments, defined as a prescription for a patient eligible for either benefits investigation or the Company’s Quick Start program.Zevra has seen a meaningful increase in reimbursement coverage, reaching nearly 75% of covered lives as of May 1, 2024. Arimoclomol During the quarter, the Company announced the FDA’s extension of arimoclomol’s Prescription Drug User Fee Act (PDUFA) date to September 21, 2024, and reaffirmed its intent to present the resubmission for discussion at an advisory committee meeting to be scheduled.The National Niemann-Pick Disease Foundation, along with six other NPC advocacy and research organizations, submitted a petition in support of arimoclomol with nearly 1,000 signatures from NPC patients, caregivers and physicians.In April 2024, the Company presented new long-term, real-world data from the expanded access program (EAP: NCT04316637) for the treatment of NPC at the Society for Inherited Metabolic Disorders.Zevra is preparing for the U.S. commercial launch of arimoclomol, if approved, and intends to leverage the commercial infrastructure that is in place for OLPRUVA to accelerate patient access. KP1077 The Company reported positive topline data from its placebo-controlled, double-blind, proof-of-concept Phase 2 study of KP1077 in patients with IH which showed that it was well tolerated and demonstrated early signs of potentially differentiated and clinically meaningful benefits. The full data package from our completed Phase 2 study will be presented at the upcoming SLEEP 2024 conference in early June.The Company is planning for an end-of-Phase 2 (EOP2) meeting with the FDA in the third quarter. Celiprolol The Company recently restarted recruitment of the celiprolol Phase 3 trial in VEDS, also known as the DiSCOVER trial, to support patients currently enrolled and to preserve the value of the program while conducting our portfolio review. Overview of Q1 2024 Financial Results: Net revenue for Q1 2024 was $3.4 million, compared to net revenue of $3.2 million in Q1 2023. The components of revenue during the first quarter included $2.2 million in net reimbursements from the French EAP for arimoclomol, $1.2 million of royalties and other reimbursements under the AZSTARYS® License Agreement, and de minimis sales of OLPRUVA due to limited shipments to our specialty pharmacy in Q1 2024. Research and development (R&D) expenses were $12.3 million for Q1 2024, compared to $8.7 million in Q1 2023. The increase in R&D expenses was primarily driven by an increase in spending for the KP1077 Phase 2 clinical trial that has since been completed, as well as ongoing support of the arimoclomol NDA. Selling, general and administrative (SG&A) expenses were $9.9 million for Q1 2024, compared to $7.2 million in Q1 2023. The period-over-period increase was primarily related to an increase in personnel costs and professional fees associated with the Company's investments in its commercial infrastructure. Net loss for Q1 2024 was ($16.6) million, or ($0.40) per basic and diluted share, compared to a net loss of ($13.2) million, or ($0.38) per basic and diluted share for Q1 2023. As of March 31, 2024, total shares of common stock outstanding were 41,850,494, and fully diluted common shares outstanding decreased by 1,451,966 to 56,778,630, which included 5,603,729 shares issuable upon exercise of warrants. As of March 31, 2024, total cash, cash equivalents, and investments were $52.7 million, a decrease of $15.0 million compared to $67.7 million as of December 31, 2023. The decrease was driven, in part, by increased third-party R&D costs related to the KP1077 clinical development program, reduction in accounts payable and accrued liabilities associated with the Company’s acquisition of Acer Therapeutics, and increased SG&A expenses during the period as the Company invested in its commercial infrastructure. On April 5, 2024, the Company announced the refinancing of our existing debt with up to $100 million in committed capital, which strengthened our balance sheet, simplified our debt structure, and provided non-dilutive capital flexibility. The refinancing was led by Perceptive Advisors and HealthCare Royalty Partners, premier biotech investors. From the initial draw of $60 million at closing, we have refinanced our existing debt of $43 million and added an incremental $14 million in net cash proceeds to the cash balance after fees and discounts. The facility also provides a second tranche of $20 million which can be drawn at the Company’s discretion until October 5, 2025, and a third tranche of $20 million which may be drawn upon the approval of arimoclomol, with each of the additional tranches subject to terms and conditions. Based on our current operating plan, available cash, cash equivalents and investments are expected to extend our cash runway into 2026, subject to continuing compliance with our debt covenants. The Company’s cash runway forecast includes revenue from the expected sales of OLPRUVA, ongoing reimbursements from the French EAP for arimoclomol, ongoing royalties under the AZSTARYS license agreement, investments into the incremental commercial activities needed to support the launch of arimoclomol, if approved, and completion of the KP1077 development program for IH.The Company’s cash runway forecast does not include any commercial revenue from arimoclomol which could follow a potential FDA approval, or the potential sale of the Priority Review Voucher which would be received upon approval.

Therefore, it is important to adhere to any dietary protein restrictions and have alternative medication options to help control ammonia levels. About OLPRUVA® OLPRUVA (sodium phenylbutyrate) was approved for the treatment of certain UCDs in December 2022 and has recently been marketed under the brand name, OLPRUVA®. OLPRUVA (sodium phenylbutyrate) for oral suspension is a prescription medicine used along with certain therapies, including changes in diet, for the long-term management of adults and children weighing 44 pounds (20 kg) or greater and with a body surface area (BSA) of 1.2 m2 or greater, with UCDs, involving deficiencies of carbamylphosphate synthetase (CPS), ornithine transcarbamylase (OTC), or argininosuccinic acid synthetase (AS). Please see Important Safety Information and full Prescribing Information, including Patient Information. Important Safety Information Certain medicines may increase the level of ammonia in your blood or cause serious side effects when taken during treatment with OLPRUVA. Tell your doctor about all the medicines you or your child take, especially if you or your child take corticosteroids, valproic acid, haloperidol, and/or probenecid. OLPRUVA can cause serious side effects, including: 1) nervous system problems (neurotoxicity). Symptoms include sleepiness, tiredness, lightheadedness, vomiting, nausea, headache, confusion, 2) low potassium levels in your blood (hypokalemia) and 3) conditions related to swelling (edema). OLPRUVA contains salt (sodium), which can cause swelling from salt and water retention. Tell your doctor right away if you or your child get any of these symptoms. Your doctor may do certain blood tests to check for side effects during treatment with OLPRUVA. If you have certain medical conditions such as heart, liver or kidney problems, are pregnant/planning to get pregnant or breast-feeding, your doctor will decide if OLPRUVA is right for you. The most common side effects of OLPRUVA include absent or irregular menstrual periods, decreased appetite, body odor, bad taste or avoiding foods you ate prior to getting sick (taste aversion). These are not all of the possible side effects of OLPRUVA. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088. About Niemann-Pick Disease Type C (NPC) Niemann-Pick disease type C (NPC) is an ultra-rare, progressive, and neurodegenerative lysosomal storage disorder characterized by an inability of the body to transport cholesterol and other lipids within the cell, leading to an accumulation of these substances in various tissue areas, including brain tissue. The disease is caused by mutations in the NPC1 or NPC2 genes, which are responsible for making lysosomal proteins. Both children and adults can be affected by NPC with varying clinical presentations. Those living with NPC lose independence due to physical and cognitive limitations, with key neurological impairments presenting in speech, cognition, swallowing, ambulation, and fine motor skills. Disease progression is irreversible and can be fatal within months or take years to be diagnosed and advance in severity. About Arimoclomol Arimoclomol, Zevra’s orally delivered, first-in-class investigational product candidate for the treatment of NPC, has been granted Orphan Drug designation, Fast Track designation, Breakthrough Therapy designation, and Rare Pediatric Disease designation by the FDA, and Orphan Medicinal Product designation for the treatment of NPC by the European Medicines Agency (EMA). The FDA has accepted the resubmission of the NDA for arimoclomol and has set a PDUFA date of September 21, 2024. About Idiopathic Hypersomnia (IH) Idiopathic hypersomnia (IH) is a rare sleep disorder characterized by excessive daytime sleepiness (EDS). Patients with IH experience daytime lapses into sleep, or an irrepressible need to sleep that persists even with adequate or prolonged nighttime sleep. Additionally, those with IH have extreme difficulty waking, otherwise known as sleep inertia, severe brain fog, and often fall asleep unintentionally or at inappropriate times. These symptoms of IH often lead to further, even more debilitating problems such as memory lapses, difficulty maintaining focus, and depression. It is estimated, based on claims data, that approximately 37,000 patients in the United States are currently diagnosed with IH, although the total patient population may be much larger due to some patients who have not yet been diagnosed, have been misdiagnosed, or are not currently seeking treatment. About KP1077 KP1077 (serdexmethylphenidate or SDX) is Zevra’s proprietary prodrug of d-methylphenidate (d-MPH) and its sole active pharmaceutical ingredient (API). KP1077 has been granted Orphan Drug Designation by the U.S. Food and Drug Administration (FDA) for the treatment of IH, and the U.S. Drug Enforcement Agency (DEA) has classified SDX, the sole API in KP1077, as a Schedule IV controlled substance based on evidence suggesting SDX has a lower potential for abuse when compared to d-MPH, a Schedule II controlled substance. About Celiprolol Celiprolol is an investigational clinical candidate for the treatment of Vascular Ehlers-Danlos Syndrome (VEDS). Celiprolol has been granted Orphan Drug and Breakthrough Therapy Designations by the FDA. Zevra recently restarted enrollment in the Phase 3 trial, known as DiSCOVER trial being conducted under a Special Protocol Assessment (SPA) agreement with the U.S. FDA. Celiprolol’s mechanism of action is designed to reduce the mechanical stress on collagen fibers within the arterial wall through vascular dilation and smooth muscle relaxation. About Vascular Ehlers-Danlos Syndrome Vascular Ehlers-Danlos syndrome is a rare genetic cardiovascular disorder which impairs collagen 3 rich connective tissue and leads to vascular and hollow organ ruptures.
