About the Japanese Phase II Clinical Study (M20-353)1
M20-353 study is an uncontrolled, open-label Japanese Phase II clinical study to evaluate the efficacy and safety of venetoclax in combination with obinutuzumab and venetoclax in combination with ibrutinib in Japanese patients with treatment-naïve chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL). The primary endpoint was the rate of complete response (CR) and complete response with incomplete bone marrow recovery (CRi) as assessed by an Independent Review Committee (IRC).

About the Global Phase III Clinical Study (CLL14 Study, BO25323)2
CLL14 Study (BO25323) is a multicenter, randomized, open-label global Phase III clinical study comparing venetoclax in combination with obinutuzumab versus obinutuzumab in combination with chlorambucil (not approved in Japan) in patients with treatment-naïve CLL. The primary endpoint was progression-free survival (PFS) as assessed by investigators.

About Gazyva (obinutuzumab)3
Gazyva is a glycoengineered type II anti-CD20 monoclonal antibody designed to bind to CD20, a protein expressed on certain B cells, but not on stem cells or plasma cells. Gazyva is designed to attack and destroy targeted B cells both directly and together with the body’s immune system. Chugai and Nippon Shinyaku jointly develop and market the product in Japan.

About Chronic Lymphocytic Leukemia (CLL) / Small Lymphocytic Lymphoma (SLL)
In CLL, blood stem cells in the bone marrow become excessive abnormal lymphocytes and these abnormal cells have difficulty fighting infections. As the number of abnormal cells grows there is less room for healthy white blood cells, red blood cells, and platelets4. This could result in anemia, infection, and bleeding. SLL is the same type of cancer as CLL. When lymphocytes are not located in the peripheral blood or bone marrow, the disease is called SLL5. CLL/SLL is a rare type of lymphoma accounting for less than one case in 100,000 population annually in Japan.

"In the third quarter of 2025 we focused on advancing preparations for the nebokitug Phase 3 trial in patients with primary sclerosing cholangitis (PSC), continuing our very productive discussions with the FDA and EMA," said Adi Mor, PhD, co-founder, Chief Executive Officer and Chief Scientific Officer of Chemomab. "I am delighted to report that we have support from both agencies that a single Phase 3 registration trial would be sufficient for approval. In addition, both have agreed that a composite of clinically relevant events can be used for the study endpoint. In view of the general alignment of the two regulatory agencies and the advanced status of the Phase 3 design, we expect to launch the trial as soon as feasible."

Dr. Mor continued, "We are also encouraged that at the recent AASLD 2025 conference, the PSC community, including KOLs, global clinical centers and patient advocates, voiced their support for the nebokitug Phase 3 design, along with their interest in participating in the trial. With a clear regulatory pathway to approval in the US, international regulatory alignment on key aspects of the Phase 3 trial design and increasing market interest, we are seeing growing recognition of nebokitug’s potential to become the first disease-modifying therapy for this devastating condition. The limited number of ongoing PSC trials provides a unique opportunity to leverage our strong engagement with global PSC centers to advance our Phase 3 program rapidly and efficiently. In parallel, we are continuing discussions with potential strategic partners. We see this dual track as positioning Chemomab for maximum strength and flexibility as we work to launch the Phase 3 nebokitug trial as soon as the necessary financial resources are available."

Dr. Mor concluded, "This is an exciting time for Chemomab as we see more options for advancing nebokitug into a registrational trial that could enable us to be the first effective therapy in this large, unserved market, while providing hope to the tens of thousands of PSC patients seeking better options for managing their condition. We are continuing to lay the groundwork for rapidly launching the Phase 3 trial and look forward to reporting on our progress over the remainder of the year."

Third Quarter 2025 and Recent Highlights:

On November 6, 2025, Chemomab reported that data from the Phase 2 SPRING trial assessing nebokitug for the treatment of PSC was featured in three poster presentations at the American Association for the Study of Liver Disease (AASLD) The Liver Meeting 2025. All three were designated by conference organizers as "posters of distinction." Data presented from the SPRING trial open label extension (OLE) showed the continued and consistent positive effects of nebokitug on key inflammatory and fibrotic biomarkers when administered to patients with PSC for up to 48 weeks, confirming its good safety profile and further reinforcing its disease-modifying potential. Two additional posters presented new clinical data that provided additional insights into the macrophage-related mechanism of action of nebokitug, a first-in-class antibody that inhibits the soluble protein CCL24, a key driver of disease processes in fibro-inflammatory diseases such as PSC. These results further confirm that nebokitug may halt or slow disease progression and improve clinical outcomes — the primary objectives of the proposed nebokitug Phase 3 study in PSC.

On August 14, 2025, Chemomab reported that it would change the ratio of its American Depositary Shares ("ADSs") to its Class A ordinary shares (the "ADS Ratio"), from the then current ADS Ratio of one ADS to 20 Class A ordinary shares to a new ADS Ratio of one ADS to 80 Class A ordinary shares, effective on August 26, 2025. This ratio adjustment essentially served as a one-for-four reverse ADS split for Chemomab ADS holders.
Third Quarter 2025 Financial Highlights

Cash Position: Cash, cash equivalents and short-term bank deposits were $10.2 million as of September 30, 2025, compared to $9.5 million as of June 30, 2025 and $14.2 million as of December 31, 2024. This cash is expected to fund the company through the end of the fourth quarter of 2026.

Koselugo approved in the US for adults with neurofibromatosis type 1

On November 20, 2025 Alexion and AstraZeneca reported that its Rare Disease Koselugo (selumetinib), an oral, selective MEK inhibitor, has been approved in the US for the treatment of adult patients with neurofibromatosis type 1 (NF1) who have symptomatic, inoperable plexiform neurofibromas (PN).

The approval by the US Food and Drug Administration (FDA) was based on positive results from KOMET, the largest and only placebo-controlled global Phase III trial in this patient population. Data were presented at the 2025 American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Annual Meeting and published in The Lancet.

NF1 is a rare, progressive, genetic condition usually diagnosed in early childhood, but often progressing into adulthood, that can impact every organ system. Up to 50% of people living with NF1 may develop a type of non-malignant tumour called PN that may affect the brain, spinal cord and nerves.4,5 PN may appear later in a person’s life and can grow and become large, leading to pain, disfigurement and muscle weakness, among other debilitating symptoms.

Prof. Pierre Wolkenstein, MD, PhD, Head of the Department of Dermatology at Henri Mondor Hospital, APHP, Paris East University (UPEC), and Investigator of the KOMET trial, said: "The KOMET Phase III trial, which builds on the established clinical profile of Koselugo and its real-world use in paediatric patients, underscores its potential to address the substantial and oftentimes progressive clinical burdens associated with PN in adulthood. This approval reaffirms the role of Koselugo as a strong option for the treatment of adult and paediatric patients with NF1 PN."

Marc Dunoyer, Chief Executive Officer, Alexion, said: "This expanded approval of Koselugo in adults with NF1 PN, together with the recently approved granule formulation for young children aged one year and older, enables much-needed continuity of care and supports patients across the disease journey in the US. As the first approved therapy in NF1 PN, backed by more than a decade of clinical evidence, Koselugo has transformed the treatment standard for this rare disease."

Annette Bakker, PhD, Chief Executive Officer, Children’s Tumor Foundation, said: "We celebrate this FDA approval of Koselugo for adults with NF1 plexiform neurofibromas-a major step forward for NF patients everywhere. Koselugo has already changed what is possible for children with NF1, and now adults will benefit from that same progress. It is proof that NF research is delivering real results and opening the door to even more treatment options. This milestone shows what can be achieved when scientists, clinicians, industry and the NF community work together with one focus: getting effective treatments to patients faster."

In the primary analysis of the KOMET Phase III trial, Koselugo showed a statistically significant and clinically meaningful overall response rate (ORR) of 20% (n=14/71, 95% confidence interval [CI]: 11, 31) compared to 5% with placebo (n=4/74, 95% CI: 2, 13; p=0.011) by cycle 16, with 86% of patients on Koselugo having an observed duration of response (DOR) of at least 6 months. After 12 cycles, patients on placebo were switched to Koselugo and patients on Koselugo remained on treatment for an additional 12 cycles.1

The safety of Koselugo in the KOMET Phase III trial was consistent with its known profile and established use in paediatric patients.2

Koselugo has been recently approved in the EU, Japan and other countries for the treatment of adult patients with NF1 who have symptomatic, inoperable PN based on data from the KOMET Phase III trial, and additional regulatory reviews are ongoing. In the US, Koselugo granules have recently been approved for paediatric patients one year of age and older with NF1 PN.

Notes

NF1
NF1 is a rare, progressive, genetic condition that is caused by a spontaneous or inherited mutation in the NF1 gene.3,4 NF1 is associated with a variety of symptoms, including soft lumps on and under the skin (cutaneous neurofibromas) and, in up to 50% of patients, tumours called plexiform neurofibromas (PN) may develop on the nerve sheaths.4,5 These PN can cause clinical issues such as disfigurement, motor dysfunction, pain, airway dysfunction, visual impairment and bladder or bowel dysfunction.4,5

KOMET
KOMET is a global Phase III randomised, double-blind, placebo-controlled, multicentre trial designed to evaluate the efficacy and safety of Koselugo in adults with NF1 who have symptomatic, inoperable PN. The trial enrolled 145 adults from 13 countries across North America, South America, Europe, Asia and Australia, with participants’ baseline characteristics, including gender and distribution of PN, reflective of the global adult NF1 patient population. Patients were enrolled and randomised to receive Koselugo or placebo (1:1) for 12 28-day cycles. Participants were required to have diagnosis of NF1, at least one symptomatic, inoperable PN measurable by volumetric MRI analysis, chronic PN pain score documented during screening, adequate organ and marrow function and stable chronic PN pain medication use at enrolment.2,6

The primary endpoint is confirmed overall response rate (ORR) by cycle 16 as assessed by ICR. ORR is defined as the percentage of patients with confirmed complete response (disappearance of PNs) or partial response (at least 20% reduction in tumour volume). Secondary endpoints include improved PN-related pain and health-related quality of life (HRQoL) at cycle 12.2,6

After 12 cycles, patients on placebo were switched to Koselugo and patients on Koselugo remained on treatment for an additional 12 cycles. Patients who had the opportunity to complete 24 cycles of treatment have the option to participate in a long-term extension period and continue to receive Koselugo.2,6

Koselugo
Koselugo (selumetinib) is a kinase inhibitor that blocks specific enzymes (MEK1 and MEK2), which are involved in stimulating cells to grow. In NF1, these enzymes are overactive, causing tumour cells to grow in an unregulated way creating so-called plexiform neurofibromas (PN). By blocking these enzymes, Koselugo slows down the growth of tumour cells and, therefore, the PN growth.

Koselugo is approved in the US, EU, Japan, China and other countries for the treatment of certain paediatric patients with NF1 who have symptomatic, inoperable PN.

Koselugo is approved in the US, EU, Japan and other countries for the treatment of adult patients with NF1 who have symptomatic, inoperable PN, and additional regulatory reviews are ongoing.

Koselugo has been granted Orphan Drug Designation in the US, EU, Japan and other countries for the treatment of NF1.

"The third quarter has seen a fantastic continuation of our accelerating momentum at Alpha Tau, as the pace of patient treatments continues to rise, and we draw increased interest from our peers in the industry" said Alpha Tau Chief Executive Officer Uzi Sofer. "Receiving the radioactive license approval in New Hampshire was a significant milestone in our push for operational commercial readiness, and we are continuing to develop that facility for use in treating patients in the U.S., Canada, and elsewhere, having invested almost $2 million into the facility in Q3. We are very happy with the rate of recruitment in our U.S. multi-center pilot study in pancreatic cancer, and look forward to some potential targeted near-term milestones, including a forthcoming response from the PMDA to our request for marketing authorization in Japan in treating recurrent head & neck cancer, and treating our first patients with glioblastoma multiforme (GBM) shortly. With four IDEs currently active for trials in the U.S., we are continuing to explore with the FDA other potential U.S. trial initiations, potentially in prostate cancer or head & neck cancers."

Recent Corporate Highlights:

● In September, Alpha Tau announced the treatment of the first patient in its U.S. multi-center pancreatic cancer clinical trial. The trial is expected to enroll up to 30 patients with newly diagnosed pancreatic cancer, in two cohorts: 15 patients with locally advanced disease, and 15 patients with metastatic disease. Patients will receive mFOLFIRINOX chemotherapy together with the Alpha DaRT treatment. Up to 87% of newly diagnosed pancreatic cancer patients are considered inoperable at diagnosis and face a dismal prognosis, with limited benefit from existing therapies, and the pilot study is a key part of Alpha Tau’s broader strategy to bring Alpha DaRT to cancer patients with some of the highest unmet needs. For more information, please see here: View Source

● In October, Alpha Tau announced the receipt of a radioactive material license for its New Hampshire manufacturing facility, its first commercial-scale facility. The license paves the way for the introduction of radioactive material and continued positive momentum toward initiating Alpha DaRT treatment manufacturing onsite in 2026. Total expected nameplate capacity from the first phase of construction is approximately 400,000 Alpha DaRT sources for local use, subject to a number of operational and clinical assumptions.

Expected Upcoming Milestone Targets:

● First patient treated in U.S. GBM pilot study in Q4 2025. For more information, please see here: View Source

● Response from Japan’s PMDA around year end 2025 to the application for pre-market approval of Alpha DaRT in patients with recurrent head & neck cancer.

● Completion of patient recruitment in the ReSTART pivotal U.S. multi-center trial in recurrent cutaneous squamous cell carcinoma in Q1 2026. For more information, please see here: View Source

Research and Development expenses for the nine months ended September 30, 2025 were $22.5 million, compared to $19.5 million for the same period in 2024, primarily due to an increase in employee compensation and benefits, costs of raw materials and third-party contractor expenses, reflecting increased clinical activities, as well as decreased government grants, offset by lower share-based compensation expenses and travel expenses.

Marketing expenses for the nine months ended September 30, 2025 were $1.4 million, compared to $1.7 million for the same period in 2024, due to decreased employee compensation and benefits and decreased marketing conference activities and travel expenses.

General and Administrative expenses for the nine months ended September 30, 2025 were $5.8 million, compared to $4.6 million for the same period in 2024, primarily due to increased employee compensation and benefits, including share-based compensation and professional fees (including legal and IR expenses), offset by a decrease in travel expenses and D&O insurance costs.

Financial expense, net, for the nine months ended September 30, 2025 was $0.6 million, compared to financial income, net, of $3.5 million for the same period in 2024, primarily due to an increase in the remeasurement of warrants, a decrease in interest from bank deposits, and changes in foreign exchange rates.

For the nine months ended September 30, 2025, the Company had a net loss of $30.5 million, or $0.39 per share, compared to a net loss of $22.3 million, or $0.32 per share, in the nine months ended September 30, 2024.

Balance Sheet Highlights

As of September 30, 2025, the Company had cash and cash equivalents, short-term deposits and restricted deposits of $75.9 million, compared to $62.9 million at December 31, 2024.

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.
