"We are pleased to share these initial data in frontline NSCLC patients showing silevertinib’s activity against a broad spectrum of 35 distinct non-classical EGFR mutations," said Mark Velleca, M.D., Ph.D., President and Chief Executive Officer of Black Diamond Therapeutics. "We are particularly encouraged by the CNS activity of silevertinib in treating NSCLC patients with brain metastases, as published data clearly demonstrate that CNS metastases are a key factor in early disease progression for NCM NSCLC patients treated with second- and third-generation EGFR-TKIs. We also believe that silevertinib is uniquely positioned as a potential treatment for patients with newly diagnosed EGFR-altered GBM, and plan to initiate a randomized Phase 2 trial in the first half of 2026, while PFS data matures in our Phase 2 NSCLC study and we continue our partnering discussions."

Silevertinib Phase 2 1L NSCLC Initial Clinical Results and Program Update

43 frontline NSCLC patients harboring a broad spectrum of 35 distinct non-classical EGFR mutations were enrolled, including 16 patients with brain metastases (7 of whom had measurable CNS target lesions). All patients were enrolled at a 200mg oral daily dose of silevertinib. Efficacy and safety were assessed with a November 3, 2025 data cutoff; median follow-up time as of this date was 7.2 months and the study remains ongoing.

Key data highlights include:

For the 43 patients enrolled, preliminary efficacy data is as follows:

25 confirmed partial responses, 1 confirmed complete response
60% Objective Response Rate (ORR by RECIST 1.1)
86% CNS ORR (by RANO-BM)
91% disease control rate (DCR)

Initial duration of treatment data:

29 patients remain on therapy (5/29 after progression), longest ongoing for >19 months

Summary of safety data:

No new safety signals observed
Adverse events (AEs) experienced by a majority of patients include rash, stomatitis, diarrhea and paronychia
AEs were managed with standard supportive care and dose interruptions/reductions without compromising response depth or durability to date

The Company expects to present updated results from the Phase 2 NSCLC trial, including Duration of Response (DOR) and Progression-free Survival (PFS) data in both the recurrent (83 patients) and frontline (43 patients) settings, at a medical meeting in the second quarter of 2026. Black Diamond continues to explore potential partnerships to advance silevertinib into pivotal development.

"These highly encouraging data speak to the potential of silevertinib to be the treatment of choice for frontline NSCLC patients with the full spectrum of non-classical EGFR mutations" said Sergey Yurasov, M.D., Ph.D., Black Diamond’s Chief Medical Officer. "We are struck by the compelling CNS response rate, which may translate to prolonged durability of response for patients with CNS metastases. Based on these data, and promising Phase 0/1 and Phase 1 GBM results, we are preparing to initiate a randomized Phase 2 trial of silevertinib in newly diagnosed GBM patients, one of the highest unmet needs in oncology."

GBM Program Update and Phase 2 Plans
Approximately 50% of patients with glioblastoma (GBM) present with an oncogenic EGFR alteration that can be targeted by silevertinib; each year approximately 7,000 patients in the U.S. are diagnosed with GBM harboring these EGFR alterations.

"Prior attempts to treat EGFR-altered GBM patients have been limited by poor brain penetrance of targeted therapies and/or lack of potency of these therapies on the full spectrum of EGFR alterations" said Elizabeth Buck, Ph.D., Chief Scientific Officer of Black Diamond. "Based on encouraging CNS activity demonstrated by silevertinib across multiple trials, and its preclinical potency on all EGFR alterations found in GBM, we believe that silevertinib has the potential to be the first targeted therapy for these patients."

Black Diamond plans to initiate a randomized Phase 2 trial in newly diagnosed GBM patients in the first half of 2026, with preliminary data expected in 2028.

Key trial highlights include:

Expected to enroll approximately 150 newly diagnosed patients, randomized to receive TMZ (control arm) or silevertinib + TMZ (experimental arm)
Initial focus will be on EGFRvIII-positive patients (approximately 30% of GBM) who are MGMT-negative (unmethylated)
Randomization and treatment will begin after patients have had their surgical resection and radiation
Primary endpoint is PFS (RANO by Blinded Independent Committee Review), with an interim analysis; secondary endpoint is overall survival (OS)
Trial will be governed by an Independent Data Monitoring Committee (IDMC)

Updated Financial Guidance

Black Diamond previously reported cash, cash equivalents and investments of approximately $135.5 million as of September 30, 2025, which the Company now believes is sufficient to fund its anticipated operating expenses and capital expenditure requirements into the second half of 2028.
Financial guidance assumes Black Diamond funds the Phase 2 trial of silevertinib in ND GBM and a potential partner funds pivotal development in NSCLC. Financial guidance does not assume receipt of potential development milestones from the Company’s partnership with Servier Pharmaceuticals LLC for BDTX-4933 (now S241656).

Conference Call Information

Black Diamond will host a conference call and webcast on Wednesday, December 3, 2025, at 8:00 AM ET to discuss the preliminary Phase 2 data for silevertinib in 1L NSCLC and plans for a Phase 2 trial of silevertinib in GBM. The webcast may be accessed online here or by visiting the Events page in the Investors section of the Company’s website at www.blackdiamondtherapeutics.com.

bioAffinity Technologies’ Noninvasive CyPath® Lung Test to Be Highlighted at American Cancer Society National Lung Cancer Roundtable

On December 3, 2025 bioAffinity Technologies, Inc. (Nasdaq: BIAF; BIAFW), a biotechnology company advancing noninvasive diagnostics for lung cancer and other lung diseases, reported that Chief Medical Officer Gordon Downie, MD, PhD, will present a poster at the American Cancer Society National Lung Cancer Roundtable (NLCRT) showcasing three cases in which CyPath Lung, a noninvasive sputum-based flow cytometry test, successfully identified Stage 1A lung cancer in patients with atypical and diagnostically challenging presentations.

"Indeterminate pulmonary nodules pose a significant and growing clinical burden, especially when clinicians are confronted with conflicting or inconclusive diagnostic data," Dr. Downie said. "Risk calculators, imaging, genetic testing, and biomarker tools can at times point in opposing directions, leaving clinicians and patients uncertain about next steps. This challenge is amplified in patients with unusual risk profiles, discordant imaging and advanced age."

Dr. Downie’s poster, "CyPath Lung in Practice: From Uncertainty to Clarity and Confidence," details three complex cases from his tenure as Director of the Titus Regional Hospital Lung Nodule Clinic and Interventional Pulmonology. CyPath Lung was used alongside other diagnostic tools, including standard low-dose CT (LDCT), PET imaging, risk calculators, bronchoscopy and blood serum marker tests. In each case, CyPath Lung provided clarity and actionable results which led to confirmed diagnoses at the earliest and most treatable stage.

"These three cases illustrate scenarios that are increasingly common in real-world lung nodule practice," Dr. Downie said. "Incorporating CyPath Lung into the diagnostic pathway can accelerate diagnosis, guide difficult conversations with anxious patients, and prevent unnecessary invasive procedures that carry their own risks."

The NLCRT is a coalition of 194 medical, public health, advocacy, government, and corporate organizations that work together to fight lung cancer by working collectively and collaboratively to reduce lung cancer mortality. This year’s annual meeting is December 8-9, 2025, at the Grand Hyatt Atlanta in Buckhead, Atlanta, Georgia.

Dr. Downie’s poster session is scheduled for Monday, December 8, 2025, from 2:35-3:15 p.m. ET. The poster can be viewed on the bioAffinity website.

About CyPath Lung

CyPath Lung uses proprietary advanced flow cytometry and artificial intelligence (AI) to identify cell populations in patient sputum that indicate malignancy. Automated data analysis helps determine if cancer is present or if the patient is cancer-free. CyPath Lung incorporates a fluorescent porphyrin that is preferentially taken up by cancer and cancer-related cells. Clinical study results demonstrated that CyPath Lung had 92% sensitivity, 87% specificity and 88% accuracy in detecting lung cancer in patients at high risk for the disease who had small lung nodules less than 20 millimeters. Diagnosing and treating early-stage lung cancer can improve outcomes and increase patient survival. For more information, visit www.cypathlung.com.

AKIR001 publication in The Journal of Nuclear Medicine supports ongoing clinical development

On December 3, 2025 Akiram Therapeutics, a Swedish biotech company specializing in targeted radiotherapy, reported that data on its CD44v6-targeted radiotherapeutic candidate AKIR001 have been published in The Journal of Nuclear Medicine, one of the leading journals in nuclear medicine. The publication summarizes key studies underpinning the ongoing first-in-human Phase 1 trial at Karolinska University Hospital. It reports high tumor selectivity, favorable safety and dosimetry findings, and antitumor effects in multiple preclinical models.

The article, titled "Preclinical Validation of [177Lu]Lu-AKIR001, a CD44v6-Targeted Radiotherapeutic Entering First-in-Human Trials," presents foundational data supporting the clinical development of AKIR001. The study shows that the candidate exhibits a favorable tumor-to-organ profile, with sustained retention in tumors and low uptake in normal tissue — key characteristics of radiopharmaceuticals. The combined findings from biodistribution, dosimetry and specificity analyses confirm that 177Lu-AKIR001 demonstrates clear and selective targeting of CD44v6-expressing tumors.

The efficacy and safety results further strengthen the rationale for clinical evaluation, with clear dose-dependent antitumor activity and low uptake in normal tissues across several preclinical systems. These findings provide important scientific validation for Akiram’s CD44v6-targeted approach and support the ongoing first-in-human trial in patients with tumors that express CD44v6.

"These results bring together years of systematic development around our CD44v6 platform—spanning antibody engineering, dosimetry, in vivo studies and safety assessments. Having the work peer-reviewed adds an extra layer of confidence as the drug is now being evaluated in patients at Karolinska University Hospital. For us, it reaffirms that we are advancing on a solid and well-supported scientific foundation," says Marika Nestor, CEO of Akiram Therapeutics.

About the Phase 1 clinical trial
The ongoing first-in-human Phase 1 trial is conducted and sponsored by Karolinska University Hospital. The study evaluates safety, tolerability, pharmacokinetics and biodistribution in patients with tumors that express CD44v6, including anaplastic and iodine-refractory thyroid cancer, head and neck squamous cell carcinoma, gynecological squamous cell carcinoma and non-small cell lung cancer.
The trial is registered at ClinicalTrials.gov: View Source

Greenwich LifeSciences Provides Global Update on FLAMINGO-01, Screening Over 1,000 Patients to Date

On December 3, 2025 Greenwich LifeSciences, Inc. (Nasdaq: GLSI) (the "Company"), a clinical-stage biopharmaceutical company focused on its Phase III clinical trial, FLAMINGO-01, which is evaluating GLSI-100, an immunotherapy to prevent breast cancer recurrences, reported the following global update on FLAMINGO-01.

Flamingo-01 Progress to Date

The Company has achieved a major milestone by screening over 1,000 patients in Flamingo-01, continuing its screening rate of approximately 150 patients per quarter or the equivalent of 600 patients per year in approximately 40 US sites and 100 EU sites for a total of 140 active sites. The Company is considering a strategy to continue enrolling in both the HLA-A*02 and non-HLA-A*02 arms until interim analyses are conducted and the appropriate size of each arm can be further assessed.

CEO Snehal Patel commented, "Reaching 1,000 screened patients confirms that the interest from doctors and patients is high. The clinical site start-up activities in Europe in 2025 have further increased the momentum in the study. We are also receiving interest from other countries to join FLAMINGO-01, driven by patient interest. The high screening rate will give the Company many options, including the opportunity to continue enrollment through multiple interim analyses, the potential to realize higher enrollment rates and event rates, and the potential to maximize indications by analyzing efficacy across multiple HLA types in larger patient populations."

About FLAMINGO-01 and GLSI-100

FLAMINGO-01 (NCT05232916) is a Phase III clinical trial designed to evaluate the safety and efficacy of GLSI-100 (GP2 + GM-CSF) in HER2 positive breast cancer patients who had residual disease or high-risk pathologic complete response at surgery and who have completed both neoadjuvant and postoperative adjuvant trastuzumab based treatment. The trial is led by Baylor College of Medicine and currently includes US and European clinical sites from university-based hospitals and academic and cooperative networks with plans to open up to 150 sites globally. In the double-blinded arms of the Phase III trial, approximately 500 HLA-A*02 patients will be randomized to GLSI-100 or placebo, and up to 250 patients of other HLA types will be treated with GLSI-100 in a third arm. The trial has been designed to detect a hazard ratio of 0.3 in invasive breast cancer-free survival, where 28 events will be required. An interim analysis for superiority and futility will be conducted when at least half of those events, 14, have occurred. This sample size provides 80% power if the annual rate of events in placebo-treated subjects is 2.4% or greater.
