On August 12, 2025 Merck (NYSE: MRK), known as MSD outside the United States and Canada, reported positive topline results from the Phase 3 KEYNOTE-905 trial (also known as EV-303) in patients with muscle-invasive bladder cancer (MIBC) who are ineligible for cisplatin-based chemotherapy (Press release, Merck & Co, AUG 12, 2025, View Source [SID1234655107]). In this study, KEYTRUDA (pembrolizumab) plus Padcev (enfortumab vedotin-ejfv), given before and after surgery (radical cystectomy), demonstrated a statistically significant and clinically meaningful improvement in event-free survival (EFS), the study’s primary endpoint, as well as overall survival (OS) and pathologic complete response (pCR) rate, key secondary endpoints, compared to surgery (radical cystectomy) alone.

"Patients with muscle-invasive bladder cancer who are ineligible for cisplatin-based chemotherapy have not seen any treatment advance beyond surgery and face high rates of disease recurrence and a poor prognosis, even after having their bladder removed," said Dr. Christof Vulsteke, MD, PhD, head of Integrated Cancer Center Ghent (IKG) and Clinical Trial Unit Oncology Ghent and KEYNOTE-905 principal investigator. "The KEYNOTE-905 study results mark the first time a systemic treatment approach, used before and after surgery, significantly extended survival over standard-of-care surgery in this population, demonstrating the potential of this combination to address a critical unmet need."

The trial, evaluating Merck’s KEYTRUDA, an anti-PD-1 therapy, plus Padcev, an antibody-drug conjugate (ADC), was conducted in collaboration with Pfizer (previously Seagen) and Astellas and builds on the clinical success of this combination in locally advanced or metastatic urothelial cancer. The trial is continuing to evaluate the secondary EFS, OS, and pCR rate endpoints for neoadjuvant and adjuvant KEYTRUDA versus surgery alone as they continue to mature.

"There is a real and pressing need for more effective options for patients with bladder cancer who are ineligible for cisplatin-based treatment," said Dr. Marjorie Green, senior vice president and head of oncology, global clinical development, Merck Research Laboratories. "The compelling survival results observed in this study reinforce the potential of combining KEYTRUDA with an antibody-drug conjugate to help address a significant unmet need in this vulnerable population."

The safety profile of KEYTRUDA plus Padcev in this study was consistent with the known safety profiles of each agent. No new safety signals were identified with the combination. The companies plan to share these results with regulatory authorities worldwide and will present the data at an upcoming medical meeting.

KEYTRUDA plus Padcev is approved for the treatment of adult patients with locally advanced or metastatic urothelial cancer (la/mUC) in the U.S., the European Union (EU), Japan and several other countries around the world. KEYTRUDA as monotherapy is also approved in the U.S., EU, Japan and other countries for the treatment of certain patients with la/mUC or a type of non-muscle-invasive bladder cancer (NMIBC).

Five additional Phase 3 studies are currently evaluating KEYTRUDA across all stages of bladder cancer, including non-muscle-invasive, muscle-invasive and metastatic. Three of these studies are in MIBC including KEYNOTE-866 (NCT03924856), KEYNOTE-992 (NCT04241185) and KEYNOTE-B15 (NCT04700124), which is also known as EV-304 and is being conducted in collaboration with Pfizer and Astellas. KEYTRUDA is also being evaluated in combination with Bacillus Calmette-Guerin (BCG) in patients with NMIBC in the Phase 3 KEYNOTE-676 (NCT03711032) trial, and as adjuvant treatment in patients with localized muscle-invasive urothelial carcinoma and locally advanced urothelial carcinoma KEYNOTE-123 (NCT03244384).

About KEYNOTE-905/EV-303

KEYNOTE-905, also known as EV-303, is an open-label, randomized, multi-arm, controlled, Phase 3 trial (ClinicalTrials.gov, NCT03924895) evaluating perioperative KEYTRUDA, with or without Padcev, versus surgery alone in patients with MIBC who are either not eligible for or declined cisplatin-based chemotherapy. The trial enrolled 595 patients who were randomized to receive either:

Arm A: Three cycles of preoperative KEYTRUDA, followed by surgery to remove the bladder (radical cystectomy), followed by 14 cycles of postoperative KEYTRUDA;
Arm B: Surgery alone;
Arm C: Three cycles of preoperative KEYTRUDA plus enfortumab vedotin, followed by surgery to remove the bladder (radical cystectomy), followed postoperatively by six cycles of KEYTRUDA plus enfortumab vedotin and then eight cycles of KEYTRUDA alone.
The primary objective of this trial was to compare EFS between arm C and arm B, defined as the time from randomization to the first occurrence of any of the following events: progression of disease that precludes radical cystectomy (RC) surgery or failure to undergo RC surgery in participants with residual disease, gross residual disease left behind at the time of surgery, local or distant recurrence as assessed by imaging and/or biopsy or death due to any cause. The key secondary objectives were to compare OS and difference in pCR rate between arm C and arm B, as well as EFS, OS and the difference in pCR rate between arm A and arm B. The study remains ongoing to test hypotheses between arm A and arm B.

About bladder cancer

Bladder cancer is the ninth most common cancer worldwide, diagnosed in more than 614,000 patients each year globally. Muscle-invasive bladder cancer represents approximately 30% of all bladder cancer cases. The standard treatment for patients with MIBC is neoadjuvant cisplatin-based chemotherapy followed by surgery, which has been shown to prolong survival. However, up to half of patients with MIBC are not eligible to receive cisplatin and face limited treatment options, typically undergoing surgery alone.

On August 11, 2025 Tahoe Therapeutics reported $30 million in new funding to build the definitive foundational dataset for training Virtual Cell Models (Press release, Tahoe Therapeutics, AUG 11, 2025, View Source [SID1234655088]). With this, the team will generate one billion single-cell datapoints, mapping one million drug-patient interactions, a scale previously impossible. The dataset will support the discovery of new precision medicines for cancer and beyond. Tahoe will also select a single partner to share the data and accelerate translation to clinical outcomes.

The round was led by Amplify Partners, joined by a distinguished group of investors including Databricks Ventures, Wing Venture Capital, General Catalyst, Civilization Ventures, Conviction, Mubadala Capital Ventures, and AIX Ventures.

The raise follows the release of Tahoe‑100M, the world’s first gigascale perturbative single-cell dataset, which has become foundational for teams building virtual cell models, ranging from major AI labs to focused research institutions. Open-sourced just a few months ago, Tahoe-100M has been downloaded nearly 100,000 times. The dataset and the models trained on it have already led to the discovery of promising new therapeutic candidates for major cancer subtypes as well as novel targets across multiple modalities.

Tahoe is now expanding on that foundation: the company plans to generate one billion single-cell datapoints, mapping how tens of thousands of drug molecules interact with human biology. This new dataset will expand the boundaries of biological foundation models, aiming to reduce clinical trial failure rates and accelerate the development of precision medicines.

"Building Tahoe-100M required us to invent new ways to generate single-cell data," said Nima Alidoust, co-founder and CEO of Tahoe Therapeutics. "Now, we’re applying that superpower to go 10x further. This next phase is about using these massive datasets to bring about the GPT moment for AI models of human cells, translating insights to clinical readouts, and developing new medicines with much lower clinical failure rates."

With the new capital, Tahoe is advancing its own therapeutic programs toward the clinic, while also launching a new model of strategic collaboration. The company will select a single partner, a pharmaceutical or AI company with complementary strengths, to access the forthcoming dataset. Together, the goal is to develop the first medicines powered by virtual cell models, combining Tahoe’s data with the partner’s clinical or modeling expertise.

"While structural models have accelerated molecular design, they rarely translate to clinical success — a problem that remains one of the biggest challenges in drug development," said Sunil Dhaliwal, General Partner at Amplify Partners. "Tahoe Therapeutics is uniquely positioned to move the industry past this bottleneck by generating massive drug-patient datasets and training high-dimensional, cell-based AI models. We’re proud to back this exceptional team as they combine biology and computation to accelerate clinical impact."

Tahoe founders, Nima Alidoust, Johnny Yu, Hani Goodzari, and Kevan Shokat hold deep experience in single-cell genomics, ML, and drug discovery. The company’s platform makes large-scale, single-cell drug screening across diverse patient contexts not only possible, but scalable. Built on scientific breakthroughs at UCSF, Tahoe is creating the raw materials needed to train disease-relevant foundation models of human cells and chart a new course for precision medicine.

On August 11, 2025 Thermo Fisher Scientific, the world leader in serving science, reported it has received approval from the U.S. Food and Drug Administration (FDA) for its Oncomine Dx Target Test as a companion diagnostic (CDx) to identify patients who may be candidates for HERNEXEOS (zongertinib tablets), a tyrosine kinase inhibitor (TKI), developed by Boehringer Ingelheim (Press release, Thermo Fisher Scientific, AUG 11, 2025, View Source [SID1234655087]). The test allows clinicians and pathologists to assess if non-small cell lung cancer (NSCLC) tumors harbor human epidermal growth factor receptor 2 (HER2/ERBB2) tyrosine kinase domain (TKD) activating mutations.

Lung cancer is the second most common cancer in both men and women in the United States, with NSCLC accounting for about 85–90% of all lung cancer cases.1 Among those diagnosed with NSCLC, approximately 2 to 4 percent of patients present with a HER2 mutation.2 The FDA approved HERNEXEOS on August 8, 2025 as the first and only orally administered targeted therapy for adult patients with unresectable or metastatic non-squamous non-small cell lung cancer (NSCLC) whose tumors have HER2 (ERBB2) tyrosine kinase domain activating mutations, as detected by an FDA-approved test, and who have received prior systemic therapy. This indication was approved under accelerated approval based on objective response rate and duration of response. Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial. More information and full Prescribing Information can be found at HERNEXEOS.com.

"This rare form of non-small cell lung cancer is linked to a poor prognosis and limited treatment options, making HERNEXEOS an important advancement in addressing the unmet needs of patients," said Vicky Brown, Senior Vice President and Head of Immunology, Oncology, and Eye Health, Boehringer Ingelheim. "Through our collaboration with Thermo Fisher and leveraging the company’s proven track record with companion diagnostics, we’re pleased that patients have another tool that can be used to identify those with HER2 (ERBB2) tyrosine kinase activating mutations in non-small cell lung cancer."

The Oncomine Dx Target Test received its first approval by the FDA as an NGS CDx in 2017, followed by regulatory approvals in 20 countries for 11 biomarkers and over 20 targeted therapies (availability of these approvals vary per region). The test is reimbursed by government and commercial insurers in the U.S., Europe, Japan, South Korea, and Israel, covering more than 550 million lives globally. In the US alone, it is approved for targeted therapies in NSCLC, cholangiocarcinoma (CC), astrocytoma (AC) and oligodendroglioma (OG), anaplastic thyroid cancer (ATC), medullary thyroid cancer (MTC), and thyroid cancer (TC).

"The FDA’s approval of HERNEXEOS for previously treated patients living with HER2 (ERBB2)-mutant advanced non-small cell lung cancer signifies continued success in our efforts to develop timely and accessible companion diagnostics," said Kathy Davy, president of clinical next-generation sequencing at Thermo Fisher Scientific. "We’re continuing to expand our solutions for our pharma partners, as this approval quickly follows the recent FDA approval of our latest rapid NGS solution that can deliver results in as little as 24 hours."

Operational & Corporate Updates

Operational progress continues with ivonescimab (SMT112), an investigational, potentially first-in-class bispecific antibody combining the effects of immunotherapy via a blockade of PD-1 with the anti-angiogenesis effects associated with blocking VEGF into a single molecule:

Since in-licensing ivonescimab (SMT112), from Akeso Inc. (Akeso, HKEX Code: 9926.HK) in January 2023, over 2,800 patients have been treated in clinical studies globally. Summit has rights to develop and commercialize ivonescimab in the United States, Canada, Europe, Japan, Latin America, including Mexico and all countries in Central America, South America, and the Caribbean, the Middle East, and Africa while Akeso retains development and commercialization rights for the rest of the world, including China.
Summit is developing ivonescimab in non-small cell lung cancer ("NSCLC"), specifically conducting Phase III clinical trials in the following proposed indications:
HARMONi: Ivonescimab combined with chemotherapy in patients with epidermal growth factor receptor (EGFR)-mutated, locally advanced or metastatic non-squamous NSCLC who have progressed after treatment with a third-generation EGFR tyrosine kinase inhibitor (TKI)
HARMONi-3: Ivonescimab combined with chemotherapy in first-line patients with metastatic NSCLC
HARMONi-7: Ivonescimab monotherapy in patients with first-line metastatic NSCLC whose tumors have high PD-L1 expression
In May 2025, we announced topline results from our multiregional, double-blinded, placebo-controlled, Phase III study, HARMONi.
At the prespecified primary data analysis, ivonescimab in combination with chemotherapy demonstrated a statistically significant and clinically meaningful improvement in progression-free survival (PFS), with a hazard ratio of 0.52 (95% CI: 0.41 – 0.66; p<0.00001). PFS was measured by blinded independent central radiology review committee (BICR) compared to placebo in combination with chemotherapy.
A clinically meaningful hazard ratio was observed in both Asia and ex-Asia sub-populations. The primary analysis demonstrated the consistency of the magnitude of the PFS benefit between patients randomized in Asia and ex-Asia, as well as the consistency in a single-region study (HARMONi-A) with this multiregional study.
Ivonescimab in combination with chemotherapy showed a positive trend in overall survival (OS) in the primary analysis without achieving a statistically significant benefit with a hazard ratio of 0.79 (95% CI: 0.62 – 1.01; p=0.057). This trend provides further support for its use in 2L+ EGFRm NSCLC, a setting where high unmet need continues to exist with limited approved options in the United States and other western territories. Currently there are no FDA-approved regimens that have demonstrated a statistically significant OS benefit in this patient setting. The median follow-up time for western patients was less than the median OS at the time of the analysis, and these patients may continue to be followed for long-term outcomes. Both Asian and North American patients demonstrated a positive trend in OS. The results of the primary analysis in this multiregional study were consistent with that of the single-region HARMONi-A study, which demonstrated an OS hazard ratio of 0.80 at 52% data maturity in a similar patient population.
The safety profile of ivonescimab in combination with chemotherapy was acceptable and manageable in the context of the observed clinical benefit.
Based on the results of the HARMONi clinical trial, Summit, at present time, intends to file a Biologics License Application (BLA) in order to seek approval for ivonescimab plus chemotherapy in this setting. Based on discussions with the United States Food & Drug Administration (FDA), under our determination and subject to our review, Summit will consider the timing of the filing of this BLA.
A more complete data presentation from HARMONi is intended to be shared at a future major medical conference.
In April 2025, Akeso announced that HARMONi-6 met its primary endpoint of PFS. This trial, conducted in China by our partners at Akeso with all relevant data exclusively generated, managed, and analyzed by Akeso, evaluated ivonescimab combined with platinum-based chemotherapy against tislelizumab, a PD-1 inhibitor, with the same chemotherapy in patients with locally advanced or metastatic squamous NSCLC, regardless of PD-L1 expression. HARMONi-6 showed statistically significant and clinically meaningful improvement in PFS for ivonescimab plus chemotherapy, and no new safety signals were identified. This marks the first known Phase III trial in NSCLC to show significant improvement over PD-(L)1 inhibitor therapy combined with chemotherapy in a head-to-head setting. Following the success of Akeso’s HARMONi-2 study in China, this is the second instance where ivonescimab-based regimens have demonstrated a statistically significant benefit compared to standard-of-care PD-(L)1 inhibitor-based regimens in a Phase III. The full data set for HARMONi-6 is planned to be presented at an upcoming major medical conference.
Also in April 2025, Akeso announced that ivonescimab was approved by the Chinese Health Authorities, the National Medical Products Administration (NMPA), for a second indication based on the results of the Phase III clinical trial, HARMONi-2. HARMONi-2 evaluated monotherapy ivonescimab against monotherapy pembrolizumab in patients with locally advanced or metastatic NSCLC whose tumors have positive PD-L1 expression. In conjunction with the approval announcement, Akeso announced that the results of a NMPA-requested interim OS analysis included a hazard ratio of 0.777. The analysis was conducted at 39% data maturity, with a nominal alpha level of 0.0001. HARMONi-2 is a single region, multi-center, Phase III study conducted in China sponsored by Akeso with all relevant data exclusively generated, managed, and analyzed by Akeso.
Clinical trial collaborations and investigator sponsored trials with leading organizations, including MD Anderson, the Memorial Sloan Kettering Cancer Center, and the Dana Farber Cancer Institute, among others, continue to progress and expand evaluating ivonescimab in solid tumor settings outside of metastatic NSCLC.
In June 2025, we announced a clinical collaboration with Revolution Medicines to evaluate ivonescimab in combination with three RAS(ON) inhibitors, including the multi-selective inhibitor daraxonrasib (RMC-6236), G12D-selective inhibitor zoldonrasib (RMC-9805), and G12C-selective inhibitor elironrasib (RMC-6291), in solid tumor settings with RAS mutations.
Enrollment continues in Summit’s global Phase III trials, HARMONi-3 and HARMONi-7. In addition to the enrollment in multiregional studies conducted and sponsored by Summit, our partners at Akeso are also enrolling several single-region Phase III studies exclusively in China in multiple indications, including biliary-tract cancer, triple-negative breast cancer, head and neck squamous cell carcinoma, microsatellite stable colorectal cancer, and pancreatic cancer.

Vlad Coric, M.D., Chairman and Chief Executive Officer of Biohaven, commented, "As we eagerly await a regulatory decision on the VYGLXIA (troriluzole) NDA for spinocerebellar ataxia, Biohaven has made important progress on multiple clinical stage assets this quarter, highlighted by the momentum we showcased at our recent R&D Day, where we unveiled advancements across our innovative therapeutic platforms." Dr. Coric added, "We are excited about the prospects of launching the first treatment for SCA if VYGLXIA is approved by the FDA and our commercial team is taking the appropriate steps to ensure an efficient launch to meet this high unmet need. We are also enthusiastic about the progress made across our Inflammation and Immunology (I&I) platform where we have observed compelling evidence of targeted protein degradation with our MoDE and TRAP degraders, BHV-1300 and BHV-1400. The body of evidence we have presented to date, combined with the safety profiles observed and convenient subcutaneous administration, continues to support our belief in our degrader platform’s ultimate potential in addressing a range of immune-mediated diseases. We are also very pleased with the advancement of another key pillar of our I&I platform — the brain-penetrant, TYK2/JAK1 inhibitor, BHV-8000, which has the potential to revolutionize the treatment of neuroinflammatory and neurodegenerative diseases. We initiated a pivotal Phase 2/3 study in Parkinson’s disease, an unrelenting illness for which there is an urgent need for novel therapies to halt the progression of the disease."

Dr. Coric continued, "We also continue to take bold steps in other therapeutic areas to address important unmet medical needs for patients including in our Ion Channel and Oncology platforms. Our Kv7 platform continues to advance clinical programs toward completion in epilepsy and depression, and we are pleased to hear the promising early observations of a DEE pediatric patient successfully transitioned from ezogabine to opakalim. Finally, our Oncology platform is also generating early promising clinical data, demonstrating tumor reduction in the first 6 out of 6 patients treated with BHV-1510 plus cemiplimab. Our oncology team has also been the first to advance an FGFR3-directed ADC with potential application in urothelial cancers into clinical testing."

"Biohaven is committed to following cutting edge science to attempt to help patients across multiple areas of high unmet need. For the balance of the year, we expect to deliver continued excellence in study execution and patient enrollment across key trials in our portfolio, as well as prepare for the potential commercialization of VYGLXIA in SCA if approved. We believe the SCA data supports approval in this rare, progressive and fatal indication for which no other treatments are available. Biohaven is well-positioned to execute on our commitment to transforming the treatment landscape for patients with serious and underserved diseases and we are excited to deliver on our promise to advance our programs for patients, caregivers, and shareholders in the balance of the year."

Second Quarter 2025 and Recent Business Highlights

Released new data with MoDE (Molecular Degrader of Extracellular Proteins) program: In May 2025, the Company released new positive data from the Phase 1 study of BHV-1300, a MoDE initially being developed for the treatment of common immune-mediated diseases, such as Graves’ disease and rheumatoid arthritis. In the Phase 1 multiple-dose study, subcutaneous administered BHV-1300 achieved IgG reductions up to 87%. Median maximum reductions of 83% were achieved within 18 days. The range of IgG lowering enabled by different dose levels of BHV-1300 potentially offers tunability and flexibility in dosing paradigm, with higher doses planned for management of acute conditions, and lower, less frequent dosing planned for the management of chronic disease.
Released new data with TRAP (Targeted Removal of Aberrant Protein) degrader program: In May 2025, the Company announced further data from the Phase 1 study of BHV-1400, a TRAP degrader initially being developed to target Gd-IgA1, the aberrant immunoglobulin that drives IgA Nephropathy. In the Phase 1 study, a single dose of BHV-1400 was subcutaneously administered at a dose of 500 mg and achieved rapid, deep and sustained reductions in Gd-IgA1 of up to 81%, with a median reduction of 66%. Reductions occurred within hours of each dose, were progressive, and were sustained for weeks after a single dose administration. Effects were selective, with no significant reductions observed in other immunoglobulins (IgA, IgG, IgE, or IgM).
Demonstrated early clinical activity and favorable PK profile with BHV-1510: In May 2025, the Company announced early clinical results from a Phase 1 study of BHV-1510, a next-generation Trop2-directed ADC incorporating the proprietary TopoIx payload. The data demonstrated early signs of clinical activity and a differentiated, manageable safety profile, both as monotherapy and in combination with Regeneron’s anti-PD-1, cemiplimab. Partial responses were observed across multiple tumor types with BHV-1510 monotherapy, accompanied by low rates of payload-related toxicities. The most common adverse event was stomatitis, an anticipated and manageable class effect associated with Trop2-targeted therapies. Notably, tumor reduction was seen in all six of the first patients treated with the BHV-1510 and cemiplimab combination, including confirmed partial responses. The combination regimen was well tolerated, with no dose-limiting toxicities or cases of interstitial lung disease reported in these initial cohorts. These encouraging early clinical data, along with the favorable pharmacokinetic profile and proprietary stable linker technology, support continued investigation of BHV-1510 as monotherapy and in combination with cemiplimab in difficult-to-treat tumor types, including potential evaluation in earlier lines of therapy for patients with advanced or metastatic disease.
First patient dosed with Biohaven’s TopoIx ADC, BHV-1530: In May 2025, the Company commenced dosing with BHV-1530, a potential first-in-class fibroblast growth factor receptor 3 (FGFR3)-directed ADC which utilizes the proprietary Topolx payload. BHV-1530 has potential in cancer indications driven by FGFR3 alterations and/or upregulated FGFR3 protein expression, including urothelial cancers and other solid tumors.
Phase 2/3 PD trial initiated: In May 2025, the Company commenced enrollment in a global, pivotal, Phase 2/3 study of the first-in-clinic, orally-administered, brain-penetrant, and highly selective TYK2/JAK1 inhibitor, BHV-8000, for the treatment of early Parkinson’s disease (PD).
Compassionate use of opakalim (BHV-7000) in a child with intractable epilepsy due to Kv7 gene mutation (KCNQ2 Developmental and Epileptic Encephalopathy [KCNQ2-DEE]) provides early evidence of potential clinical benefit. A child with KCNQ2-DEE and a history of intractable epilepsy who was previously maintained on ezogabine, as well as other antiepileptics, was successfully transitioned to treatment with opakalim, Biohaven’s next-generation Kv7 activator. Opakalim was administered after receiving a compassionate use request, under a single patient IND approved by the FDA, as the child was being withdrawn from ezogabine treatment. The child had multiple unsuccessful attempts in the past to taper ezogabine, leading to severe seizure exacerbations requiring admission to the hospital intensive care unit. Dosing of opakalim in this pediatric patient was selected to achieve comparable exposures as the 75mg dose being investigated in ongoing Phase 2/3 clinical trials. Following the transition, the patient demonstrated signs of therapeutic benefit as assessed by initial seizure control and a favorable side effect profile. Although generalizability of these observations is limited, given it represents a single case report of treating a KCNQ2-DEE patient and a short initial follow-up period after transition from ezogabine, the early clinical experience after initiation of opakalim, a selective Kv7 activator, is promising for its observed antiseizure effects and favorable tolerability.
Phase 3 trial in OCD with troriluzole was completed with no efficacy signal detected. The OCD development program is being ended to allow resources to be applied to other development programs. Study results will be presented at an upcoming academic meeting.

Second Quarter 2024 Financial Highlights:

Research and Development (R&D) Expenses: R&D expenses, including non-cash share-based compensation costs, were $184.4 million for the three months ended June 30, 2025, compared to $314.8 million for the three months ended June 30, 2024. The decrease of $130.5 million was primarily due to a one-time non-cash expense during the three months ended June 30, 2024, paid to Knopp for a milestone and royalty buyback related to the BHV-7000 and broader Kv7 platform. The decrease was partially offset by increased direct program costs for advancing clinical trials and preclinical research programs in 2025, including one-time developmental milestone payments of $15.0 million and $10.0 million for our BHV-8000 and BHV-1530 programs, respectively, as well as increased non-cash share-based compensation expense. Non-cash share-based compensation expense was $13.1 million for the three months ended June 30, 2025, an increase of $6.0 million as compared to the same period in 2024. Non-cash share-based compensation expense was higher in 2025 primarily due to our annual equity incentive awards granted in the first quarter of 2025.

General and Administrative (G&A) Expenses: G&A expenses, including non-cash share-based compensation costs, were $27.3 million for the three months ended June 30, 2025, compared to $19.0 million for the three months ended June 30, 2024. The increase of $8.4 million was primarily due to increased non-cash share-based compensation expense and increased expenses related to fees incurred in connection with the Note Purchase Agreement with Beetlejuice SA LLC, an affiliate of Oberland Capital Management LLC, entered into during the second quarter of 2025 (the Note Purchase Agreement) and other legal costs. Non-cash share-based compensation expense was $7.7 million for the three months ended June 30, 2025, an increase of $2.5 million as compared to the same period in 2024. Non-cash share-based compensation expense was higher in 2025 primarily due to our annual equity incentive awards granted in the first quarter of 2025.

Other Income, Net: Other income, net was $13.8 million for the three months ended June 30, 2025, compared to other income, net of $14.2 million for the three months ended June 30, 2024. The decrease of $0.4 million was primarily due to decreased investment income and an increase in non-cash losses related to changes in fair value of our notes payable liability under the Note Purchase Agreement during the second quarter of 2025, partially offset by an increase in gains recorded for the non-cash changes in the fair value of our forward contract and derivative liability recorded in connection with the amendment to our Membership Interest Purchase Agreement with Knopp Biosciences LLC in May 2024 (the Knopp Amendment).

Net Loss: Biohaven reported a net loss for the three months ended June 30, 2025 of $198.1 million, or $1.94 per share, compared to $319.8 million, or $3.64 per share, for the same period in 2024. Non-GAAP adjusted net loss for the three months ended June 30, 2025 was $166.4 million, or $1.63 per share, compared to $308.6 million, or $3.52 per share, for the same period in 2024. These non-GAAP adjusted net loss and non-GAAP adjusted net loss per share measures, more fully described below under "Non-GAAP Financial Measures," exclude non-cash share-based compensation charges and losses from the change in fair value of derivatives. A reconciliation of the GAAP financial results to non-GAAP financial results is included in the tables below.
