艾滋病，即获得性免疫缺陷综合征（AIDS），其病原体为人类免疫缺陷病毒（HIV）。现行抗逆转录病毒治疗药物的联合应用可有效抑制艾滋病进程并显著延长患者寿命，但由于HIV-1潜伏库的存在，艾滋病迄今尚无法治愈。近年发现，抗HIV广谱中和抗体（bNAb）可有效降低HIV-1病毒载量并减缓疾病进展，可能是控制HIV/AIDS的有效策略，为研发艾滋病疫苗和治愈策略带来了曙光。在《柳叶刀》子刊The Lancet HIV发表的一项1期临床试验中，来自美国国立卫生研究院（NIH）临床中心等团队评估了N6LS（新型bNAb）在健康成人中的安全性、耐受性及药代动力学特征。研究结果显示，N6LS单次或多次静脉及皮下给药后均表现出良好的安全性，血清半衰期长达48.6天，且保留了对HIV-1的广谱中和活性，是未来预防或治疗HIV的具有前景的潜在后续药物。截图来源：The Lancet HIV这是N6LS的首次人体、剂量递增、开放标签的1期试验，纳入18~50岁、HIV-1阴性的健康成人33例（1例未接受N6LS治疗、1例治疗8周后失访），探索不同给药途径（静脉或皮下）、不同剂量N6LS（5~40 mg/kg）及联合重组人透明质酸酶PH20（ENHANZE，EDP）对人体的影响，具体治疗如下：单次静脉注射，N6LS 5 mg/kg（3例）、N6LS 20 mg/kg（3例）或N6LS 40 mg/kg（3例）；单次皮下给药，N6LS 5 mg/kg（3例）；多次皮下给药，N6LS 5 mg/kg（5例），或静脉注射，N6LS 20 mg/kg（5例），每12周给药3次；单次皮下给药，N6LS 5 mg/kg（5例）或N6LS 20 mg/kg（5例），联合重组人透明质酸酶PH20；研究结果显示，与其他抗HIV-1的bNAb相似，N6LS展示出了良好的安全性特征，无一例患者发生严重安全性事件。N6LS用药后常见的局部不良反应为皮下注射部位轻中度疼痛或压痛；接受N6LS联合重组人透明质酸酶PH20的参与者均出现注射部位红斑（轻度至重度），但无需干预即可自行缓解。药代动力学分析表明，N6LS平均血清半衰期为48.6天。此外，联合重组人透明质酸酶PH20用药，可提高N6LS的生物利用度。给药后未检测到针对N6LS的功能性抗药抗体。该研究验证了N6LS在人体内的安全性和药代动力学特征，表明N6LS是预防和治疗HIV的具有前景的候选药物。N6LS与重组人透明质酸酶PH20联合用药，有望实现N6LS更高剂量的皮下安全给药，为未来HIV预防或治疗方案提供了新思路。点击文末“阅读原文/Read more”，即可访问The Lancet HIV官网阅读完整论文。推荐阅读欢迎投稿：学术成果、前沿进展、临床干货等主题均可，点此了解投稿详情。参考资料[1] Richard L Wu, Katherine V Houser, Martin R Gaudinski, et al.

(NASDAQ: HALO) ("Halozyme" or the "Company") today reported its financial and operating results for the first quarter ended March 31, 2025, provided an update on its recent corporate activities and raised its 2025 financial guidance. "2025 is off to a strong start with our current three blockbuster brands, Darzalex SC, Phesgo and VYVGART Hytrulo, continuing to demonstrate strong growth in their currently approved indications. Our four recently launched products, Ocrevus Zunovo in U.S. and Europe, Tecentriq Hybreza in U.S. and Europe, Opdivo Qvantig in U.S. and Rybrevant SC in Europe are just beginning their contributions as our partners focus on gaining and expanding coverage and reimbursement. This broadened portfolio is resulting in an unprecedented set of 11 additional growth catalysts that have happened recently or are expected to happen in the coming months. These opportunities include multiple new European and U.S. product approvals, multiple new indication approvals and multiple key reimbursement milestones supporting access for an even greater number of patients, all creating new near and longer-term growth opportunity. As a result of this momentum, I am pleased to announce we are increasing our full year 2025 financial guidance ranges and a new $250 million share buyback," said Dr. Helen Torley, president and chief executive officer, of Halozyme. "In addition, our long-term growth prospects have never been better with additional growth opportunities projected to result from our pipeline, where two products, BMS' nivolumab plus relatlimab SC and Takeda's 20% immune globulin SC, continue in Phase 3 and where ViiV and Acumen announced development progress and data in the quarter. I am also pleased to announce that we have signed our first HVAI development agreement with a current ENHANZE partner and that a different ENHANZE partner is now moving our SVAI into clinical testing," concluded Dr. Torley. First Quarter and Recent Corporate Highlights: On May 6, Halozyme announced a second $250 million share repurchase under the $750 million approved program from February 2024. In April 2025, Halozyme filed a patent infringement lawsuit against Merck Sharp & Dohme Corp. ("Merck") in the U.S. District Court in New Jersey alleging that Merck is using Halozyme's patented MDASE™ subcutaneous drug delivery technology to develop Subcutaneous ("SC") Keytruda. Halozyme is seeking damages and injunctive relief to stop Merck's infringement of Halozyme's MDASE™ intellectual property. In March 2025, Halozyme completed the first $250 million Accelerated Share Repurchase of its common stock under the $750 million approved program from February 2024. First Quarter and Recent Partner Highlights: In April 2025, Roche received a positive opinion from the European Medicines Agency's Committee for Medicinal Products for Human Use ("CHMP") recommending an update to the European Union ("EU") label for Phesgo® for human epidermal growth factor receptor 2 ("HER2")-positive breast cancer. Administration of Phesgo® outside of a clinical setting (such as in a person's home) by a healthcare professional will be possible, once safely established in a clinical setting. In April 2025, argenx received a positive opinion from the CHMP recommending European Commission approval of VYVGART® 1000mg (efgartigimod alfa) developed with ENHANZE® for SC injection as a monotherapy for the treatment of adult patients with progressive or relapsing active chronic inflammatory demyelinating polyneuropathy ("CIDP") after prior treatment with corticosteroids or immunoglobulins. In April 2025, argenx received U.S. Food and Drug Administration ("FDA") approval of VYVGART® Hytrulo prefilled syringe for self-injection for the treatment of adult patients with generalized myasthenia gravis who are anti-acetylcholine receptor antibody positive and adult patients with CIDP. In April 2025, Janssen received European Commission marketing authorization of the SC formulation of RYBREVANT® (amivantamab) with ENHANZE®, in combination with LAZCLUZE® (lazertinib), for the first-line treatment of adult patients with advanced non-small cell lung cancer ("NSCLC") with epidermal growth factor receptor ("EGFR") exon 19 deletions or exon 21 L858R substitution mutations. Additionally, RYBREVANT® (amivantamab) is approved as a monotherapy for adult patients with advanced NSCLC with activating EGFR exon 20 insertion mutations after the failure of platinum-based therapy. This represents the 10th partner product with ENHANZE® to be commercialized. In April 2025, Janssen received European Commission approval for an indication extension of DARZALEX® SC in combination with bortezomib, lenalidomide, and dexamethasone for the treatment of adult patients with newly diagnosed multiple myeloma regardless of transplant eligibility. In March 2025, Bristol Myers Squibb received a positive CHMP opinion recommending approval of Opdivo® (nivolumab) with ENHANZE® across multiple solid tumor indications. In March 2025, Acumen announced top-line results from a Phase 1 study of sabirnetug (ACU193) with ENHANZE® comparing the pharmacokinetics between SC and intravenous administrations in healthy volunteers that demonstrated weekly SC administration of sabirnetug was well-tolerated with systematic exposure supporting further clinical development. In March 2025, ViiV announced results from a Phase 2b study demonstrated N6LS administered every four months SC with ENHANZE® in combination with cabotegravir successfully maintained viral suppression in adults living with HIV who were already stable on treatment. In March 2025, Takeda announced Health Canada expanded the marketing authorization for HYQVIA® to include CIDP as a maintenance therapy after stabilization with intravenous immunoglobulin to prevent relapse of neuromuscular disability and impairment in adults. First Quarter 2025 Financial Highlights: Revenue was $264.9 million, compared to $195.9 million in the first quarter of 2024. The 35% year-over-year increase was primarily driven by royalty revenue growth and an increase in sales of bulk rHuPH20. Revenue for the quarter included $168.2 million in royalties, an increase of 39% compared to $120.6 million in the first quarter of 2024, primarily attributable to increases in revenue of VYVGART® Hytrulo, DARZALEX® SC, and Phesgo®. Cost of sales was $48.4 million, compared to $28.3 million in the first quarter of 2024. The increase in cost of sales was primarily due to an increase in product sales. Amortization of intangibles expense remained flat at $17.8 million, compared to the first quarter of 2024. Research and development expense was $14.8 million, compared to $19.1 million in the first quarter of 2024. The decrease in research and development expense was primarily due to lower compensation expense driven by resource optimization and labor allocation initiatives, and timing of planned investments in ENHANZE® related to the development of our new high-yield rHuPH20 manufacturing process. Selling, general and administrative expense was $42.4 million, compared to $35.1 million in the first quarter of 2024. The increase was primarily due to an increase in consulting and professional service fees and compensation expense. Operating income was $141.5 million, compared to $95.5 million in the first quarter of 2024. Net income was $118.1 million, compared to $76.8 million in the first quarter of 2024. EBITDA and Adjusted EBITDA were $162.0 million, compared to $115.7 million in the first quarter of 2024.1 GAAP diluted earnings per share was $0.93, compared to $0.60 in the first quarter of 2024. Non-GAAP diluted earnings per share was $1.11, compared to $0.79 in the first quarter of 2024.1 Cash, cash equivalents and marketable securities were $747.9 million on March 31, 2025, compared to $596.1 million on December 31, 2024. The increase was primarily a result of cash generated from operations. Financial Outlook for 2025 The Company is raising its financial guidance for 2025. Note that the guidance reflects tariffs that are currently implemented. For the full year 2025, the Company expects: Total revenue of $1,200 million to $1,280 million, representing growth of 18% to 26% over 2024 total revenue, primarily driven by increases in royalty revenue. Revenue from royalties of $750 million to $785 million, representing growth of 31% to 37% over 2024. Adjusted EBITDA of $790 million to $840 million, representing growth of 25% to 33% over 2024. Non-GAAP diluted earnings per share of $5.30 to $5.70, representing growth of 25% to 35% over 2024. The Company's earnings per share guidance does not consider the impact of potential future share repurchases.

Note Regarding Use of Non-GAAP Financial Measures In addition to disclosing financial measures prepared in accordance with U.S. generally accepted accounting principles ("GAAP"), this press release and the accompanying tables contain certain non-GAAP financial measures. The Company reports earnings before interest, taxes, depreciation, and amortization ("EBITDA"), adjusted EBITDA, Non-GAAP diluted earnings per share, Non-GAAP diluted shares, and guidance with respect to those measures, in addition to, and not as a substitute for, or superior to, financial measures calculated in accordance with GAAP. The Company calculates non-GAAP diluted earnings per share excluding share-based compensation expense, amortization of debt discounts, intangible asset amortization, one-time changes, if any, such as changes in contingent liabilities, inventory adjustments, impairment charges, and certain adjustments to income tax expense. The Company calculates non-GAAP diluted shares excluding the dilutive impact of convertible notes which is used in calculating non-GAAP diluted earnings. The Company calculates EBITDA excluding interest, taxes, depreciation and amortization. The Company calculates adjusted EBITDA excluding one-time items, if any, such as changes in contingent liabilities, inventory adjustments, impairment charges and transaction costs for business combinations. Reconciliations between GAAP and Non-GAAP financial measures are included at the end of this press release. The Company does not provide reconciliations of forward-looking adjusted measures to GAAP due to the inherent difficulty in forecasting and quantifying certain amounts that are necessary for such reconciliation, including adjustments that could be made for changes in share-based compensation expense and the effects of any discrete income tax items. For the same reasons, the Company is unable to address the probable significance of the unavailable information. The Company provides non-GAAP financial measures that it believes will be achieved; however, it cannot accurately predict all of the components of the adjusted calculations and the U.S. GAAP measures may be materially different than the non-GAAP measures. The Company evaluates other items of income and expense on an individual basis for potential inclusion in the calculation of Non-GAAP financial measures and considers both the quantitative and qualitative aspects of the item, including (i) its size and nature, (ii) whether or not it relates to the Company's ongoing business operations and (iii) whether or not the Company expects it to occur as part of the Company's normal business on a regular basis. Non-GAAP financial measures do not have any standardized meaning and are therefore unlikely to be comparable to similarly titled measures presented by other companies. These non-GAAP financial measures are not meant to be considered in isolation and should be read in conjunction with the Company's consolidated financial statements prepared in accordance with GAAP, and are not prepared under any comprehensive set of accounting rules or principles. In addition, from time to time in the future there may be other items that the Company may exclude for purposes of its non-GAAP financial measures, and the Company may in the future cease to exclude items that it has historically excluded for purposes of its non-GAAP financial measures. The Company considers these non-GAAP financial measures to be important because they provide useful measures of the operating performance of the Company, exclusive of factors that do not directly affect what the Company considers to be its core operating performance, as well as unusual events. The non-GAAP measures also allow investors and analysts to make additional comparisons of the operating activities of the Company's core business over time and with respect to other companies, as well as assessing trends and future expectations. The Company uses non-GAAP financial information in assessing what it believes is a meaningful and comparable set of financial performance measures to evaluate operating trends, as well as in establishing portions of our performance-based incentive compensation programs. Safe Harbor Statement In addition to historical information, the statements set forth in this press release include forward-looking statements including, without limitation, statements concerning the Company's financial performance (including the Company's expected financial outlook for 2025) and expectations for future growth, profitability, total revenue, royalty revenue, EBITDA, Adjusted EBITDA, and non-GAAP diluted earnings-per-share and potential share repurchases under its share repurchase program. Forward-looking statements regarding the Company's ENHANZE® drug delivery technology may include the possible benefits and attributes of ENHANZE®, its potential application to aid in the dispersion and absorption of other injected therapeutic drugs and facilitating more rapid delivery and administration of higher volumes of injectable medications through subcutaneous delivery and the expected expiration date of our ENHANZE® patent in Europe. Forward-looking statements regarding the Company's business may include potential growth and receipt of royalty and milestone payments driven by our partners' development and commercialization efforts, potential new clinical trial study starts and clinical data, regulatory submissions and product launches, the size and growth prospects of our partners' drug franchises, potential new or expanded collaborations (including potential HVAI and SVAI collaborations) and collaborative targets and regulatory review, and potential approvals of new partnered or proprietary products, and the potential timing of these events. These forward-looking statements are typically, but not always, identified through use of the words "expect," "believe," "enable," "may," "will," "could," "intends," "estimate," "anticipate," "plan," "predict," "probable," "potential," "possible," "should," "continue," and other words of similar meaning and involve risk and uncertainties that could cause actual results to differ materially from those in the forward-looking statements. Actual results could differ materially from the expectations contained in these forward-looking statements as a result of several factors, including unexpected levels of revenues, expenditures and costs, unexpected delays in the execution of the Company's share repurchase program, unexpected results or delays in the growth of the Company's business, or in the development, regulatory review or commercialization of the Company's partnered or proprietary products, regulatory approval requirements, uncertainties in tariffs and trade policies, unexpected adverse events or patient outcomes and competitive conditions. In addition, there can be no assurance as to developments related to the litigation referred to in this press release, the outcome of the litigation or any remedies that could be awarded in connection with the litigation. These and other factors that may result in differences are discussed in greater detail in the Company's most recent Annual Report on Form 10-K and Quarterly Report on Form 10-Q filed with the Securities and Exchange Commission. Except as required by law, the Company undertakes no duty to update forward-looking statements to reflect events after the date of this release.
