Aura Biosciences Announces CEO Transition as Company Advances Phase 3 CoMpass Trial Toward Enrollment Completion

On May 4, 2026 Aura Biosciences, Inc. (NASDAQ: AURA), a clinical-stage biotechnology company developing precision therapies for solid tumors designed to preserve organ function, reported that its Board of Directors has appointed Natalie Holles as Chief Executive Officer and President and member of the Board of Directors, effective April 30, 2026. Ms. Holles succeeds Elisabet de los Pinos, Ph.D., the Company’s founder, who stepped down from her roles as Chief Executive Officer and President and member of the Board of Directors on the same date.

The Company also announced that its Phase 3 CoMpass trial with its investigational candidate belzupacap sarotalocan (bel-sar) for the treatment of early choroidal melanoma is nearing enrollment completion. As of today, 86 patients have been enrolled in the study, and more than 25 additional patients have been scheduled or identified for screening through May 2026. With this update, the Company reiterates its guidance to enrollment completion by mid-2026 and topline data from the CoMpass trial in the second half of 2027.

"I am thrilled to join Aura to lead the Company through this next phase of its growth, including Phase 3 trial completion and the potential registration and commercial launch of bel-sar," said Ms. Holles. "With the potential to bring the first frontline, vision-preserving therapy to patients with early choroidal melanoma, I believe the Company is very well-positioned for meaningful value creation for our patients and shareholders. I look forward to working with this talented team to advance our work toward realizing the full clinical and commercial potential of bel-sar."

"We are delighted to welcome Natalie as CEO at this important moment for Aura," said David Johnson, Chairman of the Board of Directors of Aura Biosciences. "Natalie brings significant experience across late-stage development, operations, and rare disease commercialization, making her exceptionally well-suited to lead Aura as we near completion of enrollment in our Phase 3 CoMpass trial and prepare for potential commercialization. On behalf of the Board, I would like to thank Elisabet for her leadership and vision in founding Aura and advancing the Company to this critical point."

"It has truly been a privilege to found and lead Aura from the ground up and to work alongside such an extraordinary team," said Dr. de los Pinos. "I am deeply proud of what we have built together—advancing innovation in oncology, our commitment to patients and the field of ocular oncology, and bringing the CoMpass trial to this important stage. As the Company moves into its next phase, I am excited to see it continue to grow and thrive under Natalie’s leadership."

Ms. Holles has more than 25 years of executive leadership experience spanning corporate strategy, business development, operations and commercialization across multiple therapeutic areas. Prior to joining Aura, Ms. Holles served as Chief Executive Officer of Third Harmonic Bio from August 2021 through December 2025. Before that, she was President and Chief Executive Officer of Audentes Therapeutics, which was acquired by Astellas Pharma in 2020. She joined Audentes as Senior Vice President and Chief Operating Officer in 2015, was an instrumental architect of the Company’s GMP viral vector manufacturing capabilities and was subsequently promoted to President and Chief Operating Officer in 2018, and

then to Chief Executive Officer in 2020. Earlier in her career, Ms. Holles served as Senior Vice President of Corporate Development at Hyperion Therapeutics, which was acquired by Horizon Pharma in 2015, and as Vice President of Business Development at KAI Pharmaceuticals, which was acquired by Amgen in 2012. Ms. Holles holds an A.B. in Human Biology from Stanford University and an M.A. in Molecular, Cellular and Developmental Biology from the University of Colorado, Boulder.

About Bel- sar and Aura’s Ongoing Phase 3 CoMpass Trial in Early Choroidal Melanoma: CoMpass is the first registration-enabling study in early choroidal melanoma.

Alpha Tau Announces 100% Local Disease Control Rate and Favorable Safety Profile Observed in Alpha DaRT® Pancreatic Cancer Trials Presented at DDW 2026

On May 4, 2026 Alpha Tau Medical Ltd. (Nasdaq: DRTS, DRTSW) ("Alpha Tau"), the developer of the innovative alpha-radiation cancer therapy Alpha DaRT, reported the presentation of updated pooled results from two first-in-human clinical trials of Alpha DaRT in pancreatic ductal adenocarcinoma (PDAC) at Digestive Disease Week (DDW) 2026, the world’s premier international gastroenterology conference.

The abstract, entitled "Updated Results of Feasibility, Safety, and Tumor Control in Two First-In-Human Trials of a Novel Alpha-Emitting Radionuclide for Pancreatic Adenocarcinoma," was selected for podium presentation in the Pancreatic Cancer I: Diagnosis and Treatment session. The abstract is based on combined data from two clinical protocols conducted at Hadassah Medical Center in Jerusalem, Israel, and was presented by Philip Blumenfeld, MD, Director of Advanced Radiotherapy Unit, Sharett Institute of Oncology, Hadassah Medical Center. This marks the first time that Alpha DaRT clinical results have been selected for oral presentation at a major gastroenterology conference.

Clinical Results

The results were pooled from two clinical studies of Alpha DaRT treating localized unresectable and metastatic pancreatic cancers in a heterogeneous patient population, including those who were ineligible to receive chemotherapy as well as those who had undergone up to four prior lines of chemotherapy. Despite this breadth and complexity of clinical backgrounds, 100% local disease control was achieved across all 19 evaluable patients based on modified RECIST v1.1 criteria, as measured by best overall response, reflecting 15 (79%) with stable disease and 4 (21%) with partial response, a landmark result underscoring the potential of Alpha DaRT as a compelling intratumoral treatment regardless of prior treatment history.

The safety profile was also highly encouraging. Among 26 subjects treated, only 8 device-associated adverse events were observed in 7 subjects (27%), all of which resolved within two weeks, with the exception of one instance of lingering fatigue.

Uzi Sofer, CEO of Alpha Tau, stated: "These results represent a highly significant milestone for Alpha DaRT and for Alpha Tau’s strategic mission to establish intratumoral alpha-emitting radiotherapeutics as a meaningful option in oncology’s most challenging indications. What makes these data particularly compelling is not only the efficacy and safety signal – which are both exceptional – but also the fact that this treatment was designed to integrate naturally into the existing patient pathway and GI workflow. The ability to deliver Alpha DaRT via EUS, a procedure which gastroenterologists already perform routinely, makes this treatment highly attractive from a clinical adoption perspective. Furthermore, the combination of a localized treatment with systemic approaches represents a major advantage over combinations of other systemic therapies with chemotherapy regimens, which often carry significant toxicity burdens. We believe Alpha DaRT has the potential to fundamentally change how pancreatic cancer is treated, and these results bring us closer to realizing that potential."

"These are some of the most challenging, heavily pre-treated patients in oncology – patients for whom available options are extremely limited," commented Robert Den, MD, Chief Medical Officer of Alpha Tau. "Nevertheless, consistency of response across such a diverse cohort is a powerful signal of Alpha DaRT’s potential. Coupled with a very promising safety profile characterized by low rates of device-associated adverse events and rapid resolution, these results provide a strong foundation for the advancement of Alpha DaRT in pancreatic cancer and further reinforce the scientific basis for our ongoing U.S. multicenter pancreatic cancer IMPACT trial."

Philip Blumenfeld, MD, Director of Advanced Radiotherapy Unit, Sharett Institute of Oncology, Hadassah Medical Center, and presenter of the abstract, commented: "As a radiation oncologist and member of a multidisciplinary pancreatic cancer team, I see these results as potentially addressing a significant unmet need from several clinical perspectives. Pancreatic cancer has historically been relatively resistant to radiation therapy, and while modern techniques such as SBRT have improved our ability to deliver ablative doses, their use remains constrained by the close proximity of critical gastrointestinal structures. As a result, achieving meaningful local control without toxicity continues to be a major challenge. The ability to deliver intratumoral alpha-particle therapy via EUS, with consistent disease control across treated patients, hopefully represents an important advance in the radiotherapeutic management of this disease. Equally notable is the favorable toxicity profile. In a patient population already heavily burdened by aggressive systemic chemotherapy, a treatment that offers strong local efficacy with minimal added toxicity is highly compelling. This combination makes Alpha DaRT a treatment I am genuinely excited about for my patients."

About Alpha DaRT

Alpha DaRT (Diffusing Alpha-emitters Radiation Therapy) is designed to enable highly potent and conformal alpha-irradiation of solid tumors by intratumoral delivery of radium-224 impregnated sources. When the radium decays, its short-lived daughters are released from the sources and disperse while emitting high-energy alpha particles with the goal of destroying the tumor. Since the alpha-emitting atoms diffuse only a short distance, Alpha DaRT aims to mainly affect the tumor, and to spare the healthy tissue around it.

ADC Therapeutics Reports First Quarter 2026 Financial Results and Provides Operational Updates

On May 4, 2026 ADC Therapeutics SA (NYSE: ADCT), a commercial-stage global leader and pioneer in the field of antibody drug conjugates (ADCs), reported financial results for the first quarter ended March 31, 2026, and provided recent operational updates.

"During the first quarter, we continued to build momentum across our ZYNLONTA program," said Ameet Mallik, Chief Executive Officer of ADC Therapeutics. "Looking ahead, we have multiple near-term catalysts, including topline results from LOTIS-5 anticipated in the second quarter, full results expected from both LOTIS-5 and LOTIS-7 by year-end, as well as additional updates from the investigator-initiated studies in indolent lymphomas ahead. We believe that we are well-positioned to expand ZYNLONTA’s role across B-cell malignancies, accelerating our expected growth trajectory starting in 2027."

First Quarter 2026 Operational Updates and Upcoming Milestones

LOTIS-5 topline results anticipated in 2Q 2026. The Company continues to expect to announce topline results from the LOTIS-5 Phase 3 confirmatory trial of ZYNLONTA (loncastuximab tesirine-lpyl) in combination with rituximab in the second quarter of 2026, with full results anticipated by year-end. If positive, the Company intends to submit a supplemental Biologics License Application (sBLA) to the U.S. Food and Drug Administration (FDA) before year-end, with potential compendia inclusion in the first half of 2027 and confirmatory approval in 2L+ diffuse large B-cell lymphoma (DLBCL) thereafter.

LOTIS-7 trial ongoing with data anticipated by year-end. The LOTIS-7 Phase 1b trial evaluating ZYNLONTA in combination with the bispecific antibody glofitamab (COLUMVI) in patients with relapsed or refractory (r/r) DLBCL is ongoing, with expected completion of enrollment at the selected 150 µg/kg dose in the first half of 2026. The Company plans to share full data at a medical meeting and through publication by the end of 2026. The Company also intends to evaluate potential regulatory and compendia pathways.

Investigator-Initiated trials (IITs) evaluating ZYNLONTA in additional B-cell malignancies progressing. The University of Miami Sylvester Comprehensive Cancer Center-led multi-center trials of ZYNLONTA in combination with rituximab to treat r/r follicular lymphoma (FL) and ZYNLONTA as a monotherapy to treat marginal zone lymphoma (MZL) are ongoing. The Company anticipates publication of data from both IITs between the end of 2026 and mid-2027. Assuming positive data, the Company intends to assess potential regulatory and compendia pathways.

First Quarter 2026 Financial Results

Product Revenues: Net product revenues were $20.0 million for the first quarter of 2026, as compared to $17.4 million for the first quarter of 2025. The increase in revenue versus the prior year was primarily driven by volume increase, which reflects the normal variability in customer ordering patterns as well as higher price.

License Revenues and Royalties: License revenue and royalties were $0.8 million for the first quarter of 2026, as compared to $5.6 million for the first quarter of 2025. The decrease was primarily driven by a prior year milestone received from our partner.

Cost of Product Sales: Cost of product sales was $3.6 million for the first quarter of 2026, as compared to $2.1 million for the first quarter of 2025. The increase in cost of product sales was primarily attributable to a $1.2 million increase in certain personnel costs, which includes a change in focus of these personnel from research and development clinical supply activities to commercial manufacturing activities.

Research and Development (R&D) Expense: R&D expense was $19.9 million for the first quarter of 2026, as compared to $28.9 million for the first quarter of 2025. The decrease was primarily driven by a $6.1 million decrease in external costs as a result of discontinued programs and completion of the IND-enabling activities for our PSMA-targeting ADC. The decrease was also driven by a shift of certain personnel costs totaling $2.1 million to cost of product sales ($1.2 million), inventory capitalization ($0.6 million), and selling and marketing expense ($0.3 million), reflecting a change in focus of these personnel from research and development activities toward commercial manufacturing and fulfillment activities.

Selling and Marketing (S&M) Expense: S&M expense was $12.7 million for the first quarter of 2026, as compared to $10.6 million for the first quarter of 2025. The increase was primarily due to higher wages and benefits, and marketing and advertising expenses.

General & Administrative (G&A) Expense: G&A expense was $9.9 million for the first quarter of 2026, as compared to $10.0 million for the first quarter of 2025.

Total Operating Expenses and Adjusted Total Operating Expenses: Total operating expenses were $46.1 million for the first quarter of 2026, as compared to $51.5 million for the first quarter of 2025. On a non-GAAP basis, total adjusted operating expenses were $42.9 million for the first quarter of 2026, as compared to $49.1 million for the first quarter of 2025. The reduction in total adjusted operating expenses was primarily driven by lower R&D expenses.

Net Loss and Adjusted Net Loss: Net loss for the first quarter of 2026 was $33.0 million, or a net loss of $0.21 per basic and diluted share, as compared to a net loss of $38.6 million, or a net loss of $0.36 per basic and diluted share, for the first quarter of 2025. Adjusted net loss, which is a non-GAAP financial measure, was $19.7 million, or an adjusted net loss of $0.13 per basic and diluted share, for the first quarter of 2026, as compared to adjusted net loss of $24.0 million, or $0.22 per basic and diluted share, for the first quarter of 2025. The lower net loss and adjusted net loss were primarily due to lower operating expenses and on a per basic and diluted share basis, by a higher number of weighted average shares outstanding.

Cash and Cash Equivalents: As of March 31, 2026, cash and cash equivalents were $231.0 million, compared to $261.3 million as of December 31, 2025, a change primarily driven by cash used in operations and for annual bonus payments. The Company has an expected cash runway at least into 2028.
