"The first half of 2025 was driven by focused execution across our business with the achievement of several research milestones with our collaborators and within our internal preclinical pipeline, the advancement of cemsidomide toward label-enabling trials and continued financial discipline that resulted in extending cash runway. We recently completed enrollment in the ongoing cemsidomide Phase 1 trials in multiple myeloma and non-Hodgkin’s lymphoma and look forward to sharing the full Phase 1 multiple myeloma data in September, which we believe further demonstrate cemsidomide’s best-in-class potential. Our recent Type C meeting with the FDA enabled refinement of our cemsidomide registrational development plans and we remain on track to initiate registrational development in early 2026," said Andrew Hirsch, president and chief executive officer of C4 Therapeutics. "Additionally, as part of C4T’s commitment to strategic capital allocation and despite cemsidomide’s compelling response rates observed in non-Hodgkin’s lymphoma, we are prioritizing cemsidomide multiple myeloma registrational development as we believe this has the highest potential for patient impact and value creation."

SECOND QUARTER 2025 HIGHLIGHTS AND RECENT ACHIEVEMENTS

Cemsidomide:

Completed enrollment and dose escalation for the Phase 1 trial of cemsidomide in multiple myeloma (MM) and non-Hodgkin’s Lymphoma (NHL). Cemsidomide continued to demonstrate a well-tolerated profile and compelling response rates in MM and NHL. The highest dose level studied in both indications was 100 µg once daily (QD).

Data from the cemsidomide Phase 1 trial in MM was accepted as an oral presentation at the International Myeloma Society (IMS) Annual Meeting taking place from September 17 – September 20, 2025 in Toronto, Canada. The presentation will include data from all safety and efficacy evaluable MM patients from all dose levels studied.

C4T had a productive Type C meeting with the U.S. Food and Drug Administration (FDA) that enabled further refinement of the cemsidomide registrational development plan. By year-end 2025, C4T expects to align with the FDA on a recommended Phase 2 dose based on the existing Phase 1 MM data.

Additionally, C4T is on track to initiate registrational development in early 2026. The next phase of development will evaluate cemsidomide in combination with dexamethasone in the late-line MM setting and in combination with a B-cell maturation antigen bispecific T-cell engager (BCMA BiTE) for earlier lines of MM treatment.
CFT8919:

Partner Betta Pharmaceuticals continues to advance the CFT8919 Phase 1 dose escalation trial in Greater China.
Research and Discovery Collaborations:

C4T advanced its collaboration with Merck KGaA, Darmstadt, Germany (MKDG), which is focused on two projects within the KRAS family, to a milestone on one of these projects. C4T earned $1 million upon achieving this milestone.

C4T has identified multiple degraders against two novel targets outside of oncology, which are now advancing into the next phase of discovery.
KEY UPCOMING MILESTONES AND DATA PRESENTATIONS

Present data from full cemsidomide Phase 1 dose escalation in MM at IMS taking place from September 17 – September 20, 2025.

Binod Dhakal, M.D., M.S., associate professor of medicine, Medical College of Wisconsin, Division of Hematology, will present an oral presentation titled "Updated Results of a Phase 1 First-in-Human Study of Cemsidomide (CFT7455), a Novel MonoDAC Degrader, with Dexamethasone in Patients with Relapsed/Refractory Multiple Myeloma."

Management will host an investor call to discuss cemsidomide data in MM in conjunction with the IMS presentation.

Present data from cemsidomide Phase 1 dose escalation in NHL in Q4 2025.

Enable initiation of the next phase of cemsidomide clinical development in MM with new studies expected to initiate in early 2026.

Present poster analyzing cemsidomide clinical data of population pharmacokinetic and exposure-response relationships in MM and NHL at the 2025 American Conference on Pharmacometrics (ACoP 2025) on October 20, 2025.

SECOND QUARTER 2025 FINANCIAL RESULTS

Revenue: Total revenue for the second quarter of 2025 was $6.5 million, compared to $12.0 million for the second quarter of 2024. The decrease in revenue was primarily due to an $8.0 million milestone that was earned from Biogen in the second quarter of 2024 partially offset by achievement of a preclinical milestone under our MKDG collaboration and continued progress on our other collaboration programs.

Research and Development (R&D) Expense: R&D expense for the second quarter of 2025 was $26.2 million compared to $23.8 million for the second quarter of 2024. The increase in R&D expense was primarily related to clinical trial expenses for cemsidomide, in addition to increased preclinical spend as the company’s research collaborations continue to advance.

General and Administrative (G&A) Expense: G&A expense for the second quarter of 2025 was $8.8 million compared to $9.7 million for the second quarter of 2024. The decrease was primarily related to lower stock-based compensation expense.

Net Loss and Net Loss per Share: Net loss for the second quarter of 2025 was $26.0 million, compared to $17.7 million for the second quarter of 2024. Net loss per share for the second quarter of 2025 was $0.37 compared to $0.26 for the second quarter of 2024.

Cash Position and Financial Guidance: Cash, cash equivalents and marketable securities as of June 30, 2025 were $223.0 million, compared to $234.7 million as of March 31, 2025 and $267.3 million as of December 31, 2024. The decrease during the second quarter was primarily the result of cash used to fund operations and advance our programs, partially offset by cash received for milestones under our Roche and MKDG collaborations. The company expects that its cash, cash equivalents and marketable securities as of June 30, 2025 will enable the company to fund its operating plan to mid-2027.

"Given the evolving competitive and regulatory landscape, we are also exploring partnership opportunities to advance silevertinib into pivotal development and bring this potential best-in-class treatment to patients as quickly as possible."

Recent Developments & Upcoming Milestones:

Silevertinib (BDTX-1535):

In July 2025, Black Diamond completed enrollment (n=43) in the Phase 2 trial of silevertinib in frontline non-small cell lung cancer (NSCLC) patients with non-classical EGFR mutations.
In the fourth quarter of 2025, Black Diamond expects to disclose objective response rate (ORR) and preliminary duration of response (DOR) data from all patients (n=43) in the Phase 2 trial of silevertinib in frontline NSCLC with non-classical EGFR mutations.
Black Diamond is exploring partnership opportunities in NSCLC and glioblastoma (GBM) to advance silevertinib into pivotal development.
The Company plans to solicit U.S. Food and Drug Administration (FDA) feedback on a potential registrational path in frontline EGFRm NSCLC in 1H 2026, when progression free survival (PFS) data from the ongoing Phase 2 trial becomes available.

Financial Highlights

Cash Position: Black Diamond ended the second quarter of 2025 with approximately $142.8 million in cash, cash equivalents, and investments compared to $98.6 million as of December 31, 2024. Net cash used in operations was $9.2 million for the second quarter of 2025 compared to net cash used in operations of $14.7 million for the second quarter of 2024.
Research and Development Expenses: Research and development (R&D) expenses were $9.3 million for the second quarter of 2025, compared to $12.6 million for the same period in 2024. The decrease in R&D expenses was primarily due to workforce efficiencies and outlicensing of BDTX-4933 to increase focus on the development of silevertinib.
General and Administrative Expenses: General and administrative (G&A) expenses were $4.1 million for the second quarter of 2025, compared to $9.6 million for the same period in 2024. The decrease in G&A expenses was primarily due to the restructuring announced in October 2024.
Net Income/Loss: Net loss for the second quarter of 2025 was $10.6 million, as compared to a net loss of $19.9 million for the same period in 2024.

Financial Guidance

Black Diamond ended the second quarter of 2025 with approximately $142.8 million in cash, cash equivalents and investments, which the Company believes is sufficient to fund its anticipated operating expenses and capital expenditure requirements into the fourth quarter of 2027.

"Along with our partners at Kite, we are planning to execute our anticipated 2026 commercial launch with the goal of ensuring access to as many patients as could benefit as rapidly as possible. To that end, we expect to launch in over 160 authorized treatment centers in the United States within the first year on the market and to have an adequate supply to meet physician expectations. We’re committed to delivering on the potential of anito-cel by ensuring best-in-class support and operational execution alongside our partners at Kite, who are the leaders in cell therapy. We are grateful for the patients, caregivers, and physicians who participated in our multiple myeloma anito-cel program, providing us an opportunity to advance this therapy to more patients in need. We look forward to sharing longer-term data from the iMMagine-1 study later this year. Additionally, it’s exciting to have engaged with the Food and Drug Administration and have our IND cleared earlier than expected for our next AML clinical program targeting CD33 and CD123 utilizing our ARC-SparX platform."

Recent Business Progress

Presented positive preliminary data for the Phase 2 pivotal iMMagine-1 study of anito-cel in patients with relapsed or refractory multiple myeloma (RRMM) at EHA (Free EHA Whitepaper)2025. The Phase 2 iMMagine-1 data were from a May 1, 2025 data cutoff date, including all 117 patients with a median follow-up of 12.6 months and a minimum follow-up of four months after treatment with anito-cel. All patients received a single infusion of anito-cel (target dose of 115×106 CAR+ viable T cells). 100 of 117 patients (85%) were triple refractory, and 47 of 117 patients (40%) were penta refractory. Patients received a median of three prior lines of therapy, with 60 of 117 patients (51%) having received three prior lines.

Overall response rate (ORR) was 97% (114/117) with a complete response/stringent complete response (CR/sCR) rate of 68% (79/117) and a very good partial response or higher (>VGPR) rate of 85% (100/117), per International Myeloma Working Group (IMWG) criteria as investigator-assessed. Of those evaluable for minimal residual disease (MRD) testing at the time of this data cut, 93.3% (70/75) achieved MRD negativity at a minimum of 10-5 sensitivity. Six-month, 12-month, and 18-month progression-free survival (PFS) rates were 92%, 79% and 66%, respectively, and six-month, 12-month, and 18-month overall survival (OS) rates were 97%, 95%, and 90% respectively. Median PFS and median OS have not been reached.

No delayed or non-immune effector cell-associated neurotoxicity syndrome (ICANS) neurotoxicities, including no Parkinsonism, no cranial nerve palsies, and no Guillain-Barré syndrome, and no immune-mediated enterocolitis were observed with anito-cel. No additional treatment- or therapy-related deaths or Grade ≥3 cytokine release syndrome (CRS) or ICANS events occurred since the previous data presentation in December 2024.

Received clearance from the Food and Drug Administration for the clearance of an Investigational New Drug application for ACLX-004 targeting CD33 and CD123 utilizing the Company’s ARC-SparX platform.

Second Quarter 2025 Financial Highlights

Cash, cash equivalents, and marketable securities:
As of June 30, 2025, Arcellx had cash, cash equivalents, and marketable securities of $537.6 million. Arcellx anticipates that its cash, cash equivalents, and marketable securities will fund its operations into 2028.

Collaboration revenue:
Collaboration revenue was $7.6 million and $27.4 million for the quarters ended June 30, 2025 and 2024, respectively, a decrease of $19.8 million. This decrease was primarily driven by completion of dosing and manufacturing of anito-cel in the iMMagine-1 trial in the fourth quarter of 2024.

R&D expenses:
Research and development expenses were $37.6 million and $41.0 million for the quarters ended June 30, 2025 and 2024, respectively, a decrease of $3.4 million. This decrease was primarily driven by completion of dosing and manufacturing of anito-cel in the iMMagine-1 trial in the fourth quarter of 2024, partially offset by increased personnel costs, which includes non-cash stock-based compensation expense.

G&A expenses:
General and administrative expenses were $28.7 million and $21.4 million for the quarters ended June 30, 2025 and 2024, respectively, an increase of $7.3 million. This increase was primarily driven by increased commercial readiness costs and personnel costs, which includes non-cash stock-based compensation expense.

Net income or loss:
Net loss was $52.8 million and $27.2 million for the quarters ended June 30, 2025 and 2024, respectively.

"The topline results from the pivotal INFRONT-3 Phase 3 trial of latozinemab, expected by mid-fourth quarter, represent a key inflection point for Alector and for the FTD community," said Arnon Rosenthal, Ph.D., Chief Executive Officer of Alector. "FTD is a devastating form of dementia that affects people in the prime of life, has no approved treatments, and is often fatal within a decade of diagnosis. Heterozygous loss-of-function mutations in the GRN gene reduce progranulin levels by about 50%, impairing neuronal function and driving neurodegeneration. Latozinemab, our investigational therapy for FTD-GRN being developed in collaboration with GSK, is designed to restore progranulin levels in the brain. Supported by data from an open-label Phase 2 study, the FDA granted Breakthrough Therapy designation to latozinemab. The INFRONT-3 results will inform our next steps toward potential registration and may bring us one step closer to delivering a treatment for this relentless disease."

Dr. Rosenthal continued, "In parallel, we are advancing AL101 in early Alzheimer’s disease, with a placebo-controlled, double-blind, 76-week Phase 2 trial that is expected to complete in 2026. At the same time, we continue to build our preclinical and research pipeline, including brain-penetrant candidates enabled by our proprietary Alector Brain Carrier platform. Progressing late-stage clinical programs while investing in innovative early assets positions Alector to create near- and long-term value for both patients and shareholders. With a cash runway into the second half of 2027, we are well resourced to advance our scientific and strategic goals."

Sara Kenkare-Mitra, Ph.D., President and Head of Research and Development at Alector, added, "Over the past quarter, we’ve made steady progress across our wholly owned preclinical and research pipeline, including programs powered by our proprietary Alector Brain Carrier platform. This technology is designed to deliver therapeutic cargos, including antibodies, proteins, enzymes, and siRNA, across the blood-brain barrier, a critical challenge in treating neurodegeneration. Using this approach, we’re progressing brain-penetrant candidates, including our anti-amyloid beta antibody and anti-tau siRNA for Alzheimer’s disease, as well as our engineered GCase enzyme replacement therapy for Parkinson’s disease. This work underscores our commitment to developing first- and best-in-class therapies for patients with serious neurodegenerative diseases."

Recent Clinical Updates

Progranulin Programs (latozinemab (AL001) and AL101/GSK4527226) Being Developed in Collaboration with GSK

Latozinemab

Alector and GSK remain on track to report topline data by the middle of the fourth quarter of 2025 from the pivotal, 96-week, randomized, double-blind, placebo-controlled INFRONT-3 Phase 3 trial evaluating latozinemab in frontotemporal dementia due to a GRN gene mutation (FTD-GRN). Pending the trial’s outcome, the companies are preparing for potential Biologics License Application (BLA) and Marketing Authorization Application (MAA) submissions in 2026.

The statistical analysis plan (SAP) for INFRONT-3 has been amended after engagement with the U.S. Food and Drug Administration (FDA). The SAP will include plasma progranulin (PGRN) as a co-primary endpoint along with the Clinical Dementia Rating plus National Alzheimer’s Coordinating Center Frontotemporal Lobar Degeneration Sum of Boxes (CDR plus NACC FTLD-SB).

Frontotemporal dementia (FTD) is a rare neurodegenerative disease and the most common form of dementia for people under the age of 60.1 It affects an estimated 50,000 to 60,000 individuals in the United States and roughly 110,000 in the European Union.2,3 There are several heritable forms of FTD, including FTD-GRN, which is caused by mutations in the GRN gene and represents about 5% to 10% of all cases.⁴ People with FTD often begin experiencing symptoms such as behavioral changes, lapses in judgment, and diminished language skills in their 40s and 50s.1 The disease typically progresses over 7 to 10 years and is ultimately fatal.5 Currently, there are no approved treatment options for any form of FTD.1

Heterozygous loss-of-function mutations in the GRN gene lead to haploinsufficiency, reducing PGRN levels in the central nervous system by 50%. These mutations are a known genetic cause of FTD.6 PGRN is a secreted glycoprotein that regulates lysosomal function, neuronal survival, and inflammation in the brain.6

Latozinemab is a novel, investigational human monoclonal antibody (mAb) designed to block and internalize the sortilin receptor to elevate PGRN levels in the brain. It is believed to be the most advanced therapeutic candidate in development for the treatment of FTD-GRN.

Latozinemab has been granted Breakthrough Therapy and Fast Track designations by the FDA for the treatment of FTD-GRN, as well as Orphan Drug designation by both the FDA and the European Medicines Agency for the treatment of FTD.

AL101/GSK4527226

The global, randomized, double-blind, placebo-controlled PROGRESS-AD Phase 2 clinical trial of AL101/GSK4527226 in early Alzheimer’s disease (AD) is ongoing, with enrollment completed in April 2025 and trial completion expected in 2026.

AL101 is an investigational human mAb designed to block and internalize the sortilin receptor to elevate PGRN levels in the brain. It is similar to latozinemab but has distinct pharmacokinetic and pharmacodynamic properties that may make it suitable for the potential treatment of more prevalent neurodegenerative diseases.

In July 2025, Alector published a manuscript titled "Development of AL101 (GSK4527226), a progranulin-elevating monoclonal antibody, as a potential treatment for Alzheimer’s disease" in Alzheimer’s Research & Therapy. The publication outlines preclinical and Phase 1 study results, demonstrating that AL101 bound to sortilin and decreased cell surface sortilin levels, leading to consistent elevations of PGRN across in vitro, preclinical, and Phase 1 studies. These results support continued development of AL101 and its investigation as a potential treatment for AD and other neurodegenerative conditions where PGRN could play a role.

Preclinical and Research Pipeline
