"We are excited to advance our VIR-5500 Phase 1 trial with the addition of early line metastatic prostate cancer cohorts exploring combination therapy," said Marianne De Backer, M.Sc., Ph.D., MBA, Chief Executive Officer, Vir Biotechnology. "Opening Part 3 of the Phase 1 trial brings the potential benefits of the universal PRO-XTEN approach to patients earlier in their cancer journey, when treatment intervention may have the greatest impact on their long-term outcomes."

The Phase 1 clinical trial is an open-label, non-randomized study designed to assess the safety, pharmacokinetics and preliminary anti-tumor activity of VIR-5500 in combination with ARPIs in participants with metastatic prostate cancer. VIR-5500 is currently being evaluated in the same Phase 1 clinical trial as a monotherapy and has demonstrated promising early anti-tumor activity and a favorable safety profile in heavily pre-treated patients with mCRPC. VIR-5500 incorporates the universal PRO-XTEN masking technology, which is designed to enable the selective activation of the TCEs in the tumor microenvironment, mitigating damage to healthy cells and reducing toxicity.

"VIR-5500 has demonstrated potential as a monotherapy with PSA reductions in heavily pre-treated patients early in dose escalation," said Mark Eisner, MD, MPH, Chief Medical Officer, Vir Biotechnology. "Building on our understanding of VIR-5500 as a monotherapy, we look forward to evaluating the potential benefit of combining the complementary mechanisms of action of VIR-5500 and ARPIs with the goal to deliver the best possible outcomes for patients."

Prostate cancer is the most diagnosed cancer in men.1 Metastatic prostate cancer encompasses disease that has spread beyond the prostate, including both hormone-sensitive and castration-resistant forms. The disease progresses quickly and is a significant burden with limited treatment options. Despite advancements, there is still a significant unmet need for efficacious, well-tolerated treatments that can extend survival and improve quality of life.

About VIR-5500

T-cell engagers (TCEs) are powerful anti-tumor agents that can direct the immune system, specifically T-cells, to destroy cancer cells. VIR-5500 is an investigational PRO-XTEN masked TCE currently being evaluated in an open-label, non-randomized Phase 1 clinical trial (NCT05997615) designed to assess the safety, pharmacokinetics, and preliminary efficacy of VIR-5500 in participants with metastatic castration-resistant prostate cancer (mCRPC).

VIR-5500 combines a bispecific PSMA and CD3 binding TCE with the PRO-XTEN masking technology. The universal PRO-XTEN masking technology is designed to keep the TCEs inactive (or masked) until they reach the tumor microenvironment, where tumor-specific proteases cleave off the mask and activate the TCEs, leading to killing of cancer cells by T-cells. By confining the activity exclusively to the tumor microenvironment, we aim to circumvent the traditionally high toxicity associated with unmasked TCEs and increase their efficacy and tolerability. Additionally, the mask is designed to help drug candidates stay in the bloodstream longer in their inactive form, allowing them to better reach the site of action and potentially allowing less frequent dosing regimens.

"We are very pleased to have begun patient treatments on the RefleXion X1 platform," said Ari Gabayan, M.D., medical director at Beverly Hills Cancer Center. "This dual-treatment platform enables us to treat all stages of solid tumor cancers in IGRT mode and to introduce a completely new therapeutic option using the autonomous guidance of SCINTIX therapy for patients with lung and bone tumors. SCINTIX technology is unlike any other radiotherapy, and we believe it represents the next frontier in precision cancer care."

With this installation, Beverly Hills Cancer Center joins a growing network of cancer centers adopting RefleXion’s X1 platform to expand their radiotherapy capabilities. In addition to delivering conventional IGRT, Beverly Hills Cancer Center is preparing to offer SCINTIX therapy for patients with lung and bone tumors. SCINTIX therapy uses real-time biological signals emitted from cancer cells to autonomously guide radiation delivery. Patients receive an injection of a small amount of a PET tracer, fludeoxyglucose F18, which the cancer cells consume. The X1 detects the signals produced by the PET tracer and dynamically directs radiation dose to active tumor cells.

"With their first patient treatment on the X1 platform, Beverly Hills Cancer Center continues their strong tradition of delivering cutting-edge cancer treatment," said Todd Powell, president and CEO of RefleXion. "This milestone underscores the scalability and adaptability of our technology, opening access to both hospital-based and freestanding centers. It also demonstrates the growing commercial potential of our platform as we move closer to establishing SCINTIX therapy as a new standard for metastatic disease."

Recently, RefleXion announced positive results from its PREMIER registry a prospective, multi-institutional study evaluating SCINTIX therapy. Findings presented at the 2025 ASTRO Annual Meeting in San Francisco, showed local control of 100 percent via follow up imaging of up to nine months post-treatment with no reported Grade 2 or higher adverse events among 31 patients. Patients were treated for lung tumors, including early-stage and metastatic disease, or for bone metastases. These data represent the first evidence of SCINTIX therapy’s clinical impact.

On October 9, 2025 Akari Therapeutics, Plc (Nasdaq: AKTX), an oncology biotechnology company developing novel payload antibody drug conjugates (ADCs), reported that it has filed two new provisional patent applications with the United States Patent and Trademark Office (USPTO). The first application includes claims protecting Akari’s novel immuno-oncology payload, PH1 (a novel Thailanstatin analog), and its spliceosome modulatory mechanism of action, which is expected to provide a therapeutic benefit by activating the host immune system in the fight against cancer. The second patent filing includes claims for a combination therapy of PH1 pipeline ADCs with other immuno-oncology drugs that alleviate checkpoint inhibition and have demonstrated synergy with immune checkpoint inhibitors (ICIs) in preclinical models. These new patent applications are part of a growing patent portfolio strategy designed to further extend Akari’s proprietary position with respect to the Company’s novel PH1 payload. These filings also build upon Akari’s recent provisional patent filing in late September covering the use of Akari’s ADC platform to target cancer by modulating alternative splicing drivers within cancer cells.

Abizer Gaslightwala, President and Chief Executive Officer of Akari Therapeutics commented, "The filing of these two patent applications furthers our strategy to establish a framework for building a new class of immuno-oncology ADC therapies and build on the tremendous success of checkpoint inhibitors. We believe the data within our patent applications enable the potential of our PH1 payload to build novel first-in-class immune-oncology ADCs and continue to demonstrate Akari’s advances in our understanding of spliceosome modulation as a strategy to attack cancer. In particular, these two patent applications include data that highlight the unique immuno-oncology action that the PH1 payload can potentially unlock to drive differentiated clinical outcomes and remissions for cancer patients in the future."

"We look forward to sharing more details at the upcoming presentation at the Society for Immunotherapy Cancer (SITC) (Free SITC Whitepaper) Congress as an oral presentation on November 9th to highlight the progress of our exciting research on Akari’s spliceosome modulating payload PH1. These specific provisional patent applications are designed to protect our disclosures at the SITC (Free SITC Whitepaper) conference and increase the scope of our intellectual property estate, which we anticipate will enable long term value creation for Akari and potential partners we elect to work with on our ADC portfolio," concluded Mr. Gaslightwala.

To build on the Company’s current patent estate around the PH1 spliceosome modulating payload, these patent filings include data that highlights the immuno-oncology properties of Akari’s proprietary ADCs as a single agent, as well as a synergistic gain-of-function effects from the synergy created when Akari’s proprietary ADCs are combined with certain checkpoint inhibitors, as compared to either single agent-ADC or immune checkpoint inhibitor therapy.

Checkpoint inhibitors have seen historic success across several cancer types but have only benefited roughly 20-30% of patients as measured by response rates in approved cancer types. Akari’s data underscore the potential for creating a new ADC paradigm for targeting cancer via spliceosome modulation and unlocking the potential of a combination checkpoint inhibitor-PH1 ADC regimen in new and exciting ways.

The Company continues to expand its current ADC pipeline to encompass multiple targets, such as AKTX-101 (Trop2 ADC with PH1 payload), as well as future programs (AKTX-102, undisclosed target with PH1 payload).
