Under the terms of the transaction agreement among XOMA Royalty, Sub and Mural announced on August 20, 2025 (the "Transaction Agreement"), Sub has agreed to acquire the entire issued and to be issued share capital of Mural (the "Acquisition"). Under the terms of the Acquisition and subject to certain conditions, following closing, each Mural shareholder (i) would receive a base cash price of $2.035 per share (the "Base Price Per Share"), which has been calculated on the basis of Mural having approximately $36.2 million in Closing Net Cash on the Closing Net Cash Date (each as defined in the Transaction Agreement) (the "Estimated Closing Net Cash") and (ii) may receive an additional cash amount per share of up to $0.205 (the "Additional Price Per Share"), which would be calculated on the basis of the amount by which Mural’s Closing Net Cash on the Closing Net Cash Date exceeds the Estimated Closing Net Cash. The Base Price Per Share would be payable to Mural shareholders on closing of the Acquisition regardless of the actual quantum of Mural’s Closing Net Cash on the Closing Net Cash Date.

The Acquisition, excluding any amount that may be payable in respect of the Additional Price Per Share, values the entire issued and to be issued share capital of Mural at approximately $36.2 million.

The Acquisition is expected to close in the fourth quarter of 2025, subject to customary closing conditions and the sanction of the scheme of arrangement by the High Court of Ireland.

Results of Scheme Meeting and Extraordinary General Meeting

As described above, on October 24, 2025, Mural held the Scheme Meeting and EGM in Dublin, Ireland, in each case relating to the Acquisition. Both meetings were held to seek shareholder approval of the Acquisition, which will be effected by means of a "scheme of arrangement" under Chapter 1 of Part 9 of the Irish Companies Act of 2014, in accordance with Irish law. Mural shareholders approved the proposal at the Scheme Meeting and each of the proposals at the EGM that were required to approve and implement the scheme of arrangement.

There were 17,324,771 ordinary shares of Mural outstanding as of 10.00 p.m. (Irish local time) on September 18, 2025, the voting record time for the Scheme Meeting and the EGM. A quorum was present at each of the Scheme Meeting and the EGM. Because the votes required to approve the proposals at the Scheme Meeting and the EGM are based on votes properly cast at the applicable meeting, and because abstentions are not considered votes properly cast, abstentions and broker non-votes along with failures to vote have no effect on such proposals.

Mural will be filing a Current Report on Form 8-K with the U.S. Securities and Exchange Commission setting forth the final results of voting on each of the proposals submitted to a vote of Mural’s shareholders at the Scheme Meeting and the EGM. The final results of voting on each of the proposals submitted to a vote of Mural’s shareholders at the Scheme Meeting and the EGM are as follows.

Scheme Meeting

Parabilis Medicines Presents Clinical and Preclinical Data Demonstrating Broad Potential of Helicon™ Peptides at AACR-NCI-EORTC 2025

On October 24, 2025 Parabilis Medicines, a clinical-stage biopharmaceutical company committed to creating extraordinary medicines for people living with cancer, reported preliminary clinical and preclinical findings across its Helicon peptide pipeline at the AACR (Free AACR Whitepaper)-NCI-EORTC AACR-NCI-EORTC (Free AACR-NCI-EORTC Whitepaper) International Conference on Molecular Targets and Cancer Therapeutics (EORTC-NCI-AACR) (Free ASGCT Whitepaper) (Free EORTC-NCI-AACR Whitepaper) in Boston, Massachusetts.

The findings reinforce the broad potential of FOG-001, the company’s lead investigational therapy and the first-ever direct Wnt/β-catenin:TCF inhibitor, to act across a range of rare and more prevalent solid tumors linked by the same dysregulated biology of the Wnt/β-catenin pathway. Single-agent activity resulting in tumor shrinkage by at least 30% (partial response (PR)) was observed in five low-complexity tumor types, with strong scientific support as well for FOG-001’s potential in combination therapy for more complex tumors, including microsatellite-stable colorectal cancer (MSS CRC).

Together with positive preclinical read-outs demonstrating pharmacologic proof of concept for the company’s discovery-stage Helicon peptides in prostate cancer targeting the ERG and active androgen receptor (ARON) targets, these data highlight how the company’s Helicon platform can repeatably target high-impact "undruggable" targets long considered inaccessible to conventional therapeutic approaches.

"Just one week after presenting the first clinical proof that β-catenin:TCF can be drugged, we are showing the breadth of what this breakthrough could mean for science and for patients," said Mathai Mammen, M.D., Ph.D., Chairman and CEO of Parabilis Medicines. "FOG-001 is demonstrating meaningful signs of clinical activity across multiple Wnt/β-catenin-driven tumors, supporting its continued development in both simpler and more biologically complex Wnt-driven cancers through both monotherapy and combination therapy approaches."

He added, "Together with our preclinical advances in prostate cancer, the data illustrate the potential of Helicons to take on some of the toughest problems in oncology and bring forward transformative medicines that could meaningfully improve outcomes for patients."

FOG-001 Clinical and Preclinical Findings

The Wnt/β-catenin pathway — first identified as a key cancer driver over 30 years ago — is implicated in millions of cancer cases annually, spanning many rare and prevalent solid tumors as well as diseases like familial adenomatous polyposis (FAP) that predispose individuals to certain cancers, including colorectal cancer and desmoid tumors. Despite its central role in cancer biology, the pathway’s critical β-catenin:TCF transcription complex has long been considered "undruggable."

Preliminary data from the ongoing Phase 1/2 trial of FOG-001 (NCT05919264), as of mid-August 2025, show that the therapy is well tolerated with no Grade 4/5 treatment-related adverse events or discontinuations and exhibits a favorable pharmacokinetic profile. As of this early data cut, an objective response rate (ORR) of 43% and a disease control rate (DCR) of 73%, per RECIST 1.1, were observed in non-CRC patients with Wnt pathway activating mutations (WPAM). Evidence of single-agent activity was observed across numerous Wnt/β-catenin–driven tumors, particularly in those with low mutational burden, including desmoid, adamantinomatous craniopharyngioma (ACP), ameloblastoma, salivary gland cancer, and solid pseudopapillary neoplasm (SPN).

In MSS CRC, a 50% DCR was achieved within the efficacious monotherapy dose range, with molecular data confirming on-target pathway inhibition and reprogramming of the tumor microenvironment toward a more immune-active state. Complementary preclinical studies demonstrated that FOG-001 enhances the effects of standard and emerging therapies for MSS CRC—showing in these preclinical models additive or synergistic activity with each of 5-fluorouracil and anti-VEGF regimens, synergy with anti–PD-1 therapy, and combination benefit with pan-RAS and KRAS G12D inhibitors.

Together, these findings highlight FOG-001’s broad pipeline potential — warranting continued development in Wnt pathway–activated low-complexity tumors, and as a backbone for rational combination regimens in more complex cancers. The Phase 1/2 study remains ongoing across a wide range of Wnt-driven rare and common cancers, with additional data readouts expected over the coming months.

Prostate cancer pipeline expansion

Parabilis also presented preclinical data advancing its prostate cancer franchise, focused on two long-standing oncogenic drivers that currently lack effective therapies. ERG-degrading Helicon peptides potently and durably reduced ERG protein levels —overexpressed in 40–50% of prostate cancers — showing in vivo pharmacologic proof-of-concept demonstrating tumor growth inhibition and efficacy comparable to or exceeding standard of care in challenging prostate cancer models.

In parallel, allosteric ARON Helicon degraders that bind a conserved site distinct from the androgen ligand pocket, were designed to selectively target the active, agonist-bound androgen receptor. These Helicon degraders block proliferation in AR-amplified prostate cancer cells, offering a strategy to overcome resistance driven by AR mutations or amplification. Importantly, this approach also allows for effective combinations with approved and emerging treatments that target the testosterone ligand pocket. Together, these data demonstrate the repeatability of the Helicon platform in addressing high-value, historically undruggable targets in oncology.

"Our Helicons are delivering against three of the most challenging and compelling targets in oncology, from β-catenin:TCF to ERG to ARON," said Fawzi Benzaghou, M.D., Chief Medical Officer of Parabilis Medicines. "By pursuing bold science that makes the undruggable druggable, we’re opening new therapeutic possibilities for patients with few or no options. These data reinforce the power of our α-helical peptide platform to repeatedly unlock difficult targets and advance medicines with the potential for extraordinary patient impact."

About the Phase 1/2 trial of FOG-001
FOG-001 is being evaluated in a first-in-human Phase 1/2 multicenter, open-label study (NCT05919264) assessing its safety, tolerability, pharmacokinetics, pharmacodynamics, and antitumor activity. The trial includes dose-escalation and dose-expansion phases and is testing FOG-001 both as a monotherapy and in combination with other anticancer agents in patients with advanced or metastatic solid tumors likely or known to harbor a Wnt pathway–activating mutation (WPAM).

About FOG-001
FOG-001 is an investigational first-in-class competitive inhibitor of β-catenin interactions with the T-cell factor (TCF) family of transcription factors and is currently in clinical development. By directly targeting the β-catenin:TCF protein-protein interaction, FOG-001 is intended to block the Wnt signaling pathway irrespective of the various APC and β-catenin mutations that typically drive disease.

FOG-001 combines key features that distinguish it from previously reported Wnt/β-catenin pathway modulators: FOG-001 acts inside the cell where it binds directly to the key oncogenic driver β-catenin; and FOG-001 blocks the Wnt pathway at the key downstream node, disrupting the interaction between β-catenin and the TCF transcription factors, thereby abrogating the signal transmission by which Wnt pathway mutations are believed to drive oncogenesis.

FOG-001 is currently being evaluated in a first-in-human Phase 1/2 clinical trial in patients with locally advanced or metastatic solid tumors.

Nanobiotix has completed the transfer of NANORAY-312 sponsorship, initiated in 3Q2024, in the majority of regions along with the transfer of full operational control of the Phase 3 clinical trial to Johnson & Johnson ("J&J"). Following the transfer and Nanobiotix analysis of the latest information, Nanobiotix estimates that NANORAY-312 interim data will be analyzed and reported, after both the requisite number of events have been observed and the last patient has been recruited, in 1H2027.

Future guidance related to NANORAY-312 and other JNJ-1900 (NBTXR3)-related J&J-sponsored studies will be communicated by J&J. Nanobiotix will continue to provide JNJ-1900 (NBTXR3) clinical development updates and guidance related to Nanobiotix-sponsored studies as well as studies sponsored by The University of Texas MD Anderson Cancer Center.

About JNJ-1900 (NBTXR3)

JNJ-1900 (NBTXR3) is a novel, potentially first-in-class oncology product composed of functionalized hafnium oxide nanoparticles that is administered via one-time intratumoral injection and activated by radiotherapy. Its proof-of-concept was achieved in soft tissue sarcomas through a successful randomized Phase 2/3 study in 2018. The product candidate’s mechanism of action (MoA) is designed to induce significant tumor cell death in the injected tumor when activated by radiotherapy, subsequently triggering adaptive immune response and long-term anti-cancer memory. Given the physical MoA, Nanobiotix believes that JNJ-1900 (NBTXR3) could be scalable across any solid tumor that can be treated with radiotherapy and across any therapeutic combination, particularly immune checkpoint inhibitors.

Radiotherapy-activated JNJ-1900 (NBTXR3) is being evaluated across multiple solid tumor indications as a single agent or combination therapy. The program is led by NANORAY-312—a global, randomized Phase 3 study in locally advanced head and neck squamous cell cancers. In February 2020, the United States Food and Drug Administration granted regulatory Fast Track designation for the investigation of JNJ-1900 (NBTXR3) activated by radiation therapy, with or without cetuximab, for the treatment of patients with locally advanced HNSCC who are not eligible for platinum-based chemotherapy—the same population being evaluated in the Phase 3 study.

Given the Company’s focus areas, and balanced against the scalable potential of NBTXR3, Nanobiotix has engaged in a collaboration strategy to expand development of the product candidate in parallel with its priority development pathways. Pursuant to this strategy, in 2019 Nanobiotix entered into a broad, comprehensive clinical research collaboration with The University of Texas MD Anderson Cancer Center to sponsor several Phase 1 and Phase 2 studies evaluating JNJ-1900 (NBTXR3) across tumor types and therapeutic combinations. In 2023, Nanobiotix announced a license agreement for the global co-development and commercialization of JNJ-1900 (NBTXR3) with Janssen Pharmaceutica NV, a Johnson & Johnson company.

"The strong and durable antitumor activity we have observed with zoci, alongside a well-tolerated safety profile, highlights its potential to be a best-in-class, DLL3-targeted antibody-drug conjugate for small cell lung cancer," said Rafael G. Amado, M.D., President, Head of Global Research and Development, Zai Lab. "Advancing this program from Phase 1 to a global, registrational study in less than two years reflects the speed, scientific rigor, and executional excellence of our team, and marks a major milestone for Zai Lab as we advance our global programs. Furthermore, we are rapidly expanding zoci’s development into other areas of high unmet need, including first-line small cell lung cancer and neuroendocrine carcinoma, both expected to enter the registrational phase next year."

The presentation includes updated results from the Phase 1 monotherapy dose escalation and dose expansion portion of the study from 115 patients across six dose cohorts (0.8 mg/kg, 1.2 mg/kg, 1.6 mg/kg, 2.0 mg/kg, 2.4 mg/kg, and 2.8 mg/kg) as of the data cut-off date of September 15, 2025. 102 patients had the opportunity of at least one post-baseline tumor assessment per Response Evaluation Criteria in Solid Tumors version 1:1 (RECIST v1.1).

All patients in this multicenter study had progressed following platinum-based chemotherapy, and 90% of patients had progressed after immune checkpoint inhibitors. Of all patients, 44% had failed two prior lines of therapy, making this a highly pretreated population with limited therapeutic options. Eleven patients received a prior DLL3 bi-specific antibody. A total of 32% of patients had brain metastases at baseline. This study included patients in the United States, Spain, and China.

Key efficacy results include (n=102):

Zoci demonstrated a high response rate across all dose levels in patients with ES-SCLC who progressed on or after platinum-based chemotherapy. Efficacy was consistent over time with additional patients and longer follow-up.
In a subset of patients (n=53) receiving zoci as a second-line treatment, the best overall response rate (ORR) observed among patients in the 1.6 mg/kg arm (n=19) was 68%.
A high response rate was also observed in patients (n=32) with brain metastasis at baseline, including an ORR of 80% for patients without prior brain radiotherapy.
Three out of seven patients who progressed after prior tarlatamab, responded. Enrollment of tarlatamab pretreated patients continues.
The estimated median duration of response (DoR) is 6.1 months, and median progression-free survival is 5.4 months across all doses and all lines of therapy. Responses were durable and clinically meaningful in this heavily pre-treated and difficult-to-treat population. In the dose finding cohort of the study, enrollment continues for 1.2 mg/kg and 1.6 mg/kg, with nearly half of responders still ongoing at data cut-off. Enrollment is expected to complete in Q4 2025.
Responses occurred early in treatment with a median time to confirmed objective response of 6 weeks.
Key safety findings include (n=115):

Zoci continues to demonstrate a well-tolerated safety profile with longer follow-up, particularly at the 1.2 or 1.6mg/kg dose level.
In the 1.6 mg/kg dose cohort, Grade 3 or higher treatment-related adverse events (TRAE) occurred in 13% of patients and serious TRAEs occurred in 9%. No patients were discontinued due to toxicity.
There were two cases of pneumonitis and interstitial lung disease, both Grade 1, in the 72 patients treated at 1.2 or 1.6 mg/kg dose.
Across all dose cohorts, Grade 3 or higher TRAEs occurred in 20% of patients and serious TRAEs in 8%. The most common Grade 3 or higher TRAEs were anemia (10%) and neutropenia (11%). There were five patients who discontinued due to TRAEs, all in the higher dose levels.
"DLL3 represents a validated target in extensive-stage small cell lung cancer, where there is high need for new therapies given the disease’s aggressive nature and limited treatment options," said Grace Dy, M.D., Roswell Park Comprehensive Cancer Center, Buffalo, NY, and study investigator. "These new Phase 1 results for zoci, including data that show rapid and sustained responses among the patient population, especially those with poor prognostic factors, are the latest clinical evidence that further demonstrate zoci’s potential as a differentiated, DLL3-targeted ADC."

Global Phase 3 Registrational Study Opens for Patient Enrollment

The Phase 3 registrational clinical trial of zoci is a multicenter study that will enroll approximately 665 patients globally, including in North America, Asia, and Europe. The randomized, open-label study is designed to further evaluate the safety and efficacy of zoci compared to investigator’s choice single agent therapy (ICT) in patients with relapsed SCLC who have progressed on or after platinum-based first-line therapy as second-line therapy or one line of chemotherapy followed by tarlatamab. The primary endpoints are ORR assessed by Blinded Independent Central Review (BICR) per RECIST v1.1 for interim analysis and overall survival as the primary analysis. Secondary endpoints include duration of response, progression-free survival and safety.

About Small Cell Lung Cancer and Zocilurtatug Pelitecan (zoci)

Small cell lung cancer (SCLC) is one of the most aggressive and lethal solid tumors, accounting for ~15% of the approximately 2.5 million patients diagnosed with lung cancer worldwide each year1,2. Additionally, two-thirds of all SCLC patients are diagnosed at extensive stage3.

DLL3 is an antigen overexpressed in many neuroendocrine tumors, such as SCLC, and is often associated with poor clinical outcomes. Zocilurtatug pelitecan (zoci), formerly known as ZL-1310, comprises a humanized anti-DLL3 monoclonal antibody connected via a cleavable linker to a novel camptothecin derivative (a topoisomerase 1 inhibitor) as its payload. The compound was designed with a novel ADC technology platform called TMALIN, which leverages the tumor microenvironment to overcome challenges associated with first-generation ADC therapies.

Zoci received an Orphan Drug Designation from the U.S. Food and Drug Administration (FDA) in January 2025, recognizing its potential to treat patients with SCLC.
