The poster presentations will include preclinical data for the company’s two lead programs, FX-909, a first-in-class, orally available PPARG inhibitor designed to target the underlying luminal lineage biology of urothelial cancer and FX-111, a novel and highly differentiated potent and selective degrader for ARON, the transcriptionally active, hormone-bound androgen receptor for prostate cancer.

FX-909 Presentation Details:

Luminal urothelial carcinoma (UC), characterized by high PPARG expression, represents the majority of UC cases and is associated with poor clinical outcomes. In a Phase 0 study, FX-909, a first-in-class oral PPARG inhibitor, demonstrated intratumoral penetration and on-target activity, including dose-dependent PPARG modulation, increased tumor apoptosis, and enhanced CD8⁺ T-cell infiltration. Notably, combination with anti-PD-1 further amplified immune activation and suppression of tumor proliferation pathways. These findings support the potential of FX-909 to modulate the tumor microenvironment and warrant further clinical evaluation in UC.

Title: Phase 0 Intratumoral Microdevice Study of FX-909 in Bladder Cancer Demonstrates On-Target Anti-Tumor Activity and Immune Modulation, Enhanced in Combination with Anti-PD-1

Abstract ID: CT111 / 3
Session: Phase 0 and First-in-Human Phase I Clinical Trials
Date, Time: April 20, 2026, 2:00 p.m. – 5:00 p.m. PT
Location: Section 51
FX-111 Presentation Details:

Metastatic castration-resistant prostate cancer (mCRPC) remains largely driven by androgen receptor (AR) signaling, with resistance to current AR inhibitors posing a major clinical challenge. Real-world data identified distinct AR/KLK3-defined subgroups, with AR copy number amplification linked to increased AR signaling and poorer outcomes, reinforcing the central role of AR-driven biology in disease progression and identifying a high-risk, AR-driven population.

Title: AR copy number amplification and AR/KLK3 expression patterns reveal mechanisms of AR signaling inhibitor (ARSI) resistance and highlight the need for AR-directed therapeutic innovation in metastatic castration resistance prostate cancer (mCRPC)

Abstract ID: 3910 / 16
Session: Molecular Targeted Therapy
Date, Time: April 20, 2026, 2:00 p.m. – 5:00 p.m. PT
Location: Section 47
FX-111 is a novel and highly differentiated, potent and selective degrader for ARON, the transcriptionally active, hormone-bound androgen receptor. This approach offers the potential to overcome key vulnerabilities of conventional therapies that target AROFF, particularly in high-risk AR-driven disease, and has broad potential across prostate cancer at all stages.

Title: Discovery of FX-111, a first-in-class heterobifunctional degrader of transcriptionally active androgen receptor (ARON), to treat patients with AR-driven prostate cancer

Abstract ID: 5784 / 11

Telix continues to progress its industry-leading Therapeutics pipeline, which spans multiple product candidates and disease areas. Q1 2026 highlights include:

TLX591-Tx (lutetium (177Lu) rosopatamab tetraxetan): Part 1 of ProstACT Global, the Phase 3 trial of its lead prostate cancer therapy candidate, achieved its study objectives, demonstrating an acceptable safety and tolerability profile with no new safety signals observed1. No adverse drug-drug interactions were observed in TLX591-Tx combinations, demonstrating the feasibility of integrating TLX591-Tx with current standard of care therapies for mCRPC10, including ARPIs11 (enzalutamide or abiraterone) and docetaxel. Telix has commenced engagement with the FDA to present data from Part 1 and ascertain eligibility for U.S. patients to participate in Part 2 (randomized treatment expansion). Part 2 is open for enrollment in Australia, New Zealand and Canada, with site activation underway in preparation to open enrollment in China, Singapore, South Korea, Türkiye, the United Kingdom and Japan, where regulatory approvals have already been granted.
TLX250-Tx (lutetium (177Lu) girentuximab tetraxetan): Telix has opened its first clinical site and is recruiting patients for Part 1 of LUTEON12, a pivotal trial of TLX250-Tx as a monotherapy in advanced ccRCC13. Trial recruitment will initially focus ex-U.S.
TLX101-Tx (131I-iodofalan): Telix has enrolled the first patient in IPAX-BrIGHT, an international, multi-center pivotal trial of TLX101-Tx in patients with recurrent glioblastoma14. The trial is now open for enrollment in Australia, Austria and the Netherlands and has received regulatory approval to commence in Belgium.
TLX090-Tx (153Sm-DOTMP): Telix continues to dose patients in SOLACE15, a Phase 1 study of a drug candidate for treating pain in patients with osteoblastic bone metastases from prostate and breast cancers. The study was expanded this quarter to include additional U.S. sites to accelerate recruitment.
TLX597-Tx (177Lu-DOTA-HYNIC-panPSMA): TLX597-Tx is a "next generation" PSMA-targeting prostate cancer therapy candidate being developed to facilitate patient access in select geographies, where routine clinical availability to approved therapies is limited or not available. Early clinical data suggests a favorable asset biodistribution with limited uptake in healthy organs of concern (e.g., salivary glands, kidneys) relative to available 177Lu-PSMA therapies. Interim data from OPTIMAL-PSMA16, an investigator-led, randomized, dose intensification study of TLX597-Tx in mCRPC, will be presented at the International Prostate Cancer Symposium in April 2026.

"This strategic partnership with WuXi XDC represents a major milestone for Akari and a powerful validation of our novel PH1 payload technology," said Abizer Gaslightwala, President and Chief Executive Officer of Akari Therapeutics. "WuXi XDC is widely recognized as a global leader in ADC innovation, and with this partnership, we believe Akari can rapidly advance and further validate our PH1 payload on AKTX-101 in future clinical studies."

WuXi XDC’s CEO, Jimmy Li, Ph.D., added, "We are pleased to work with Akari to advance the novel PH1 payload into more advanced studies. WuXi XDC has a proven record of advancing novel ADC payloads and strives to remain at the forefront of ADC innovation. We believe we are the trusted and best partner to help Akari advance this first-in-kind RNA splicing modulating ADC payload for its use in its lead program, as well as other future ADC molecules. There is a strong need for ADC payload innovation to improve on current therapies, and WuXi XDC wants to be at the forefront working with partners like Akari to bring novel ADCs to cancer patients."

Akari’s lead program AKTX-101 is initially targeting metastatic urothelial cancer, where there continues to be significant unmet medical need particularly in the second-line treatment setting. Patients with metastatic disease that progress following first-line therapies often have limited options beyond standard chemotherapy, which offers only modest clinical benefit in this setting. The Company believes that AKTX-101 with its novel PH1 payload may provide a promising new therapeutic approach for urothelial cancer patients, while also demonstrating the broader potential of Akari’s PH1 payload platform.

AKTX-101 features Akari’s proprietary PH1 payload, a novel spliceosome modulator designed to disrupt RNA splicing in cancer cells. By targeting RNA splicing, PH1 represents a new direction for next-generation ADC therapies. Unlike traditional ADC payloads that are microtubule inhibitors or DNA-damaging agents, PH1 offers a differentiated mechanism of direct cytotoxicity as well as the unique activation of the innate and adaptive immune systems to attack cancer. In preclinical studies, AKTX-101 has demonstrated superior anti-tumor regression and complete remissions relative to other ADCs. Akari believes this differentiated mechanism positions PH1 as part of a new wave of ADC payload innovation aimed at significantly improving the therapeutic potential of antibody-drug conjugates.

Akari is working to advance its lead program, AKTX-101, into a Phase 1 clinical trial expected to initiate in late 2026 or early 2027 subject to regulatory clearance. This key clinical milestone reinforces Akari’s ongoing progress to advance its novel payload and execute its strategy to develop ADC therapies with novel payloads that have the potential to improve outcomes for cancer patients.
