To date, three patients with metastatic TNBC treated with paxalisib-based regimens have demonstrated meaningful clinical responses, including two partial responses (PRs) in trial participants and one confirmed complete metabolic response (CR) in a patient treated under an expanded access program.

Clinical Highlights

•
2 of 2 evaluable patients enrolled in the Phase 1b trial achieved partial responses

•
One advanced metastatic TNBC patient achieved a confirmed complete metabolic response following re-treatment with pembrolizumab/chemotherapy plus paxalisib (under an expanded access protocol)

•
Responses observed in patients with visceral disease and multi-organ metastases

•
Median time on treatment to date is approximately 6.1 months, with all patients continuing on therapy at the time of this update

•
Paxalisib continues to demonstrate a generally favorable safety and tolerability profile when combined with pembrolizumab and chemotherapy at the 30 mg daily dose

The ongoing Phase 1b trial is a multi-center, open-label, randomized study initiated in June 2025 designed to evaluate the safety, tolerability, and preliminary clinical activity of paxalisib in patients with advanced breast cancer, including TNBC, in combination with either: Pembrolizumab plus chemotherapy (current standard-of-care first-line regimen) or Olaparib (advanced breast cancer patients with BRCA mutations). Eligibility for the pembrolizumab-containing cohort required PD-L1–positive disease (CPS ≥10), consistent with standard-of-care practice in metastatic TNBC.

Patient 1 – Partial Response

A 61-year-old female with metastatic TNBC involving the left upper lobe of the lung, initiated treatment with paxalisib (30 mg daily) in combination with pembrolizumab and gemcitabine/carboplatin in June 2025. After nine cycles of therapy, serial imaging demonstrated continued tumor reduction at each assessment, culminating in a partial response by iRECIST criteria. The patient remains active on study.

Patient 2 – Partial Response with Complete Resolution of a Target Lesion

A 47-year-old female with extensively metastatic TNBC involving the lung, liver, bone, and lymph nodes, initiated treatment with paxalisib (30 mg daily) in combination with pembrolizumab and gemcitabine/carboplatin in October 2025. Following three treatment cycles, imaging demonstrated a partial response, including complete resolution of a target lung lesion and the patient remains active on study.

Patient 3 – Confirmed Complete Metabolic Response

A 44-year-old female with metastatic TNBC who had previously received pembrolizumab/chemotherapy experienced disease progression involving bone and lung metastases in early 2025. Although ineligible for the formal trial due to prior pembrolizumab exposure, the patient was re-treated beginning in June 2025 with pembrolizumab/chemotherapy plus paxalisib (30 mg daily) under physician supervision. On November 10, 2025, FDG PET/CT imaging demonstrated no evidence of active malignancy, consistent with a complete metabolic response. This complete metabolic response was confirmed on follow-up imaging in January 2026, and the patient remains on paxalisib and pembrolizumab therapy.

Paxalisib has been generally well tolerated in combination with pembrolizumab and chemotherapy. Approximately 75% of adverse events (AEs) were assessed as unlikely or unrelated to paxalisib. The paxalisib-related AEs were expected and predominantly mild to moderate, consistent with prior studies. At the 30 mg daily dose, one case of Grade 1 hyperglycemia has been observed, requiring no intervention. Two serious adverse events (SAEs) have been reported to date, both deemed unrelated to paxalisib.

Following an initial targeted site activation phase designed to ensure rigorous protocol execution and informed by encouraging early clinical signals from the first patients treated, the Company expects to activate two additional clinical sites by April 2026, with two further sites planned for mid-2026. Kazia continues to anticipate the targeted enrollment of twelve TNBC pts target by the end of 2026 and topline data readout in early 2027

Kazia is also evaluating paxalisib in additional breast cancer populations, including earlier-stage TNBC and hormone receptor–positive, HER2-negative (HR+ / HER2-) breast cancer, where dysregulation of the PI3K/mTOR pathway is well established. Paxalisib’s oral, once-daily administration offers a potentially convenient treatment option with minimal incremental burden to patients and clinical sites, an important consideration as the Company explores expansion into broader breast cancer populations. The Company will provide updates as these programs advance.

"While these observations represent a preliminary read from ongoing studies, the consistency and depth of responses we are seeing including tumor regression across multiple metastatic sites and a complete metabolic response are highly encouraging," said Dr. John Friend, M.D., Chief Executive Officer of Kazia Therapeutics. "Confirmed complete responses in metastatic triple-negative breast cancer are exceedingly rare, particularly in patients who have already progressed on standard therapies. These early data reinforce our belief that paxalisib has the potential to meaningfully enhance the activity of existing immunotherapy-based regimens, and we look forward to generating additional clinical and translational insights throughout the year."

On January 27, 2026 Greenwich LifeSciences, Inc. (Nasdaq: GLSI) (the "Company"), a clinical-stage biopharmaceutical company focused on its Phase III clinical trial, FLAMINGO-01, which is evaluating Fast Track designated GLSI-100, an immunotherapy to prevent breast cancer recurrences, reported additional updates on its cash burn rate and financing strategy.

The Company’s ATM financing vehicle allows the Company to sell its common stock directly into the trading market at market price. The amount raised through our ATM for 2025 exceeded the Company’s 2025 cash burn rate of approximately $9.5 million, leading to a year end cash balance of approximately $6 million as of December 31, 2025. Furthermore, the Company more than doubled its cash balance as of the close of business on January 23, 2026, to approximately $12.5 million, having raised approximately $7 million in the first three weeks of January 2026 through the ATM. The above preliminary financial figures are unaudited and are subject to change following completion of the Company’s financial audit for 2025.

CEO Snehal Patel commented, "Our financing strategy in January 2026 has been quite impressive so far without daily or constant use of the ATM. The current cash balance of $12.5 million could exceed the Company’s cash needs for all of 2026, given the $9.5 million annual burn rate in 2025 and the modest increase in cash needs over the $7 million annual burn rates in 2024 and 2023. We believe the Company’s lean structure and ongoing cost saving initiatives have been instrumental in this strategy, including the increasing number of patients entering the less expensive booster phase of Flamingo-01, due to less frequent site visits and vaccinations, and fewer more expensive site start-up costs."

Mr. Patel further added, "While our cash burn rates in 2026 and 2027 are projected to increase, the expected ongoing use of the ATM to sustain or grow the current cash balance may reduce the likelihood of the Company doing a large near term financing in 2026 or 2027, though there can be no assurance of this. Since the follow-on offering in 2020, we primarily utilized the ATM with initially Jefferies and more recently H.C. Wainwright to fund the Company. Continued use of the ATM may provide a bridge to non-dilutive funding, such as strategic/licensing partnerships or debt/royalty financing vehicles, that would further fund FLAMINGO-01 and potential commercial launch activities."

About FLAMINGO-01 Open Label Phase III Data

More than 1,000 patients have been screened with a current screen rate of approximately 600 patients per year. The 250 patient non-HLA-A*02 arm is now fully enrolled, where all patients received GLSI-100, which is 5 times more treated patients and recurrence rate data than the approximately 50 patients treated in the Phase IIb trial. The Primary Immunization Series (PIS), which includes the first 6 GLSI-100 injections over the first 6 months and is required to reach peak protection, is followed by 5 booster injections given every 6 months to prolong the immune response, thereby providing longer-term protection.

In the non-HLA-A*02 arm, a preliminary analysis of recurrence rates after the PIS is completed shows an approximately 80% reduction in recurrence rate.

This observation is trending similarly to the Phase IIb trial results and hazard ratio where HLA-A*02 patients were treated and where breast cancer recurrences were reduced up to 80% compared to a 20-50% reduction in recurrence rate by other approved products.

The immune response at baseline prior to any GLSI-100 treatment, the increasing immune response during the PIS, and the safety profile of non-HLA-A*02 patients is trending similarly to the HLA-A*02 arms of FLAMINGO-01 and to the Phase IIb study.

Analysis of the open label data from FLAMINGO-01 has been conducted in a manner that maintains the study blind. The open label recurrence rate, immune response, and safety data is based on the patients enrolled to date in FLAMINGO-01 and the data provided by the clinical sites so far, which is not completed or fully reviewed, and is thus preliminary. While comparing any preliminary FLAMINGO-01 data to the Phase IIb clinical trial data may be possible, these preliminary results are not a prediction of future results, and the results at the end of the study may differ.

About GLSI-100 Phase IIb Study

In the prospective, randomized, single-blinded, placebo-controlled, multi-center (16 sites led by MD Anderson Cancer Center) Phase IIb clinical trial of HLA-A*02 breast cancer patients, 46 HER2/neu 3+ over-expressor patients were treated with GLSI-100, and 50 placebo patients were treated with GM-CSF alone. After 5 years of follow-up, there was an 80% or greater reduction in cancer recurrences in the HER2/neu 3+ patients who were treated with GLSI-100, followed, and remained disease free over the first 6 months, which we believe is the time required to reach peak immunity and thus maximum efficacy and protection. The Phase IIb results can be summarized as follows:

80% or greater reduction in metastatic breast cancer recurrence rate over 5 years of follow-up with a peak immune response at 6 months and well-tolerated safety profile.

The PIS elicited a potent immune response as measured by local skin tests and immunological assays.

About FLAMINGO-01 and GLSI-100

FLAMINGO-01 (NCT05232916) is a Phase III clinical trial designed to evaluate the safety and efficacy of Fast Track designated 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 are planned to be randomized to GLSI-100 or placebo, and up to 250 patients of other HLA types are planned to 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.

On January 27, 2026 CytoDyn Inc. (OTCQB: CYDY) ("CytoDyn" or the "Company"), a clinical-stage oncology company advancing leronlimab, a first-in-class humanized monoclonal antibody targeting the CCR5 receptor with therapeutic potential across multiple indications, including triple-negative breast cancer (TNBC) and metastatic colorectal cancer (mCRC), reported that a compassionate benefactor has formally committed funding to support the Company’s Expanded Access Program (EAP) for patients with triple-negative breast cancer.

The benefactor, who has chosen to remain anonymous, has a longstanding interest in patient access initiatives, the potential of leronlimab, and how the Company’s recent data and mechanism of action theories might serve to offer experimental avenues to patients who have exhausted all approved treatment options. This strategic funding initiative will enable CytoDyn to set up and administer a program to expand access to leronlimab for a group of eligible patients, as determined by the U.S. Food and Drug Administration (FDA) guidelines, with advanced disease but who do not otherwise meet the enrollment criteria for the Company’s ongoing clinical trials.

"We are honored by this benefactor’s commitment to accelerating patient access to promising cancer therapies such as leronlimab," said Jacob Lalezari, M.D., CEO of CytoDyn. "This support allows us to responsibly broaden the availability of leronlimab while continuing to advance our promising clinical programs as we generate data to inform future regulatory pathways."

With Every Patient (WEP Clinical) has been engaged to serve as the clinical research organization (CRO) for the EAP, and the Company expects to formally open the program for patient referral in March 2026, assuming FDA’s allowance of the Company’s revised protocol submission. In addition to providing compassionate access to patients who have exhausted other treatment options and are otherwise unable to participate in the Company’s upcoming Phase 2 trial, the EAP program will serve as another potential avenue to observe PD-L1 induction following treatment with leronlimab, and thereby – in theory – opening a treatment pathway towards sustained remission when combined with an immune checkpoint inhibitor ("ICI"). The EAP will operate under applicable FDA guidelines, and additional information for physicians and eligible patients will be available on the Company’s website (www.cytodyn.com) as the program is rolled out in the coming weeks.

Mani Mohindru, PhD, a member of Cardiff Oncology’s Board of Directors since 2021 and a seasoned biotech executive, has been appointed interim Chief Executive Officer, effective immediately. Mark Erlander, PhD, Chief Executive Officer, and James Levine, Chief Financial Officer, have stepped down from their respective roles.

As part of this transition, Ms. Brigitte Lindsay has been promoted to the role of Chief Accounting Officer, ensuring continuity within the finance function. She has been with the Company for more than 14 years and was most recently the Senior Vice President of Finance. The Company has initiated a search for a permanent Chief Executive Officer and Chief Financial Officer.

Cardiff Oncology’s lead product candidate, onvansertib, a highly specific, oral PLK1 inhibitor, is currently in mid-stage clinical development for RAS-mutated metastatic colorectal cancer (mCRC) and is also being evaluated as a single agent and in combinations across multiple additional cancers in investigator-initiated studies, including metastatic pancreatic ductal adenocarcinoma, small cell lung cancer, triple-negative breast cancer, and chronic myelomonocytic leukemia. The leadership transition reflects the Company’s focus on execution and clinical advancement as its programs mature.

"As Cardiff Oncology prepares for the next stage of clinical and corporate development, the Board concluded that this was the right moment to align executive and financial leadership with the Company’s evolving needs," said Rodney S. Markin, MD, PhD, Chairman of the Board. "We want to express our sincere gratitude to Mark and Jamie for their significant contributions in guiding Cardiff to where it stands today—especially in the progress of our lead product candidate in first-line RAS-mutated mCRC, an area of high unmet need where there have not been any significant advancements in many years. Looking forward, we are confident in Dr. Mohindru’s ability to lead the Company at this key moment in onvansertib’s clinical development, as she brings a rare combination of deep scientific training, operational leadership, and capital markets expertise."

"Cardiff Oncology has built a strong scientific and clinical foundation around PLK1 inhibition, with onvansertib demonstrating encouraging activity in a challenging to treat patient population," said Mani Mohindru, PhD, interim Chief Executive Officer.
