The completed Phase 1 clinical study was a multicenter, open-label, two-step Phase 1a/1b trial conducted to determine the optimum dose and characterize pharmacokinetic, safety and tolerability profile of RS-0139 in patients with recurrent, locally advanced or metastatic solid tumors. The study generated the initial clinical dataset needed to assess how Sagitta-enabled targeted delivery may translate into an improved therapeutic index in a real-world oncology setting.
Key findings from the Phase 1 trial include:

• markedly improved hematologic safety compared with conventional chemotherapy,
• an encouraging overall safety and tolerability profile,
• promising early signals of antitumor activity.

RS Research is currently consolidating the full clinical dataset and completing the relevant procedural steps in preparation for future scientific and corporate disclosure of additional details.

Prof. Rana Sanyal, Co-Founder and CSO of RS Research, and Grand Prize Laureate of the EIC European Prize for Women Innovators, said: "These results are the product of years of rigorous science, persistence and translational focus. More importantly, they provide early clinical validation of our Sagitta platform, supporting our confidence that targeted delivery can meaningfully improve the therapeutic index of oncology treatments. This milestone strengthens our conviction in advancing additional candidates built on the same platform."

Sagitta is RS Research’s proprietary drug delivery platform, designed to improve therapeutic index by selectively directing cytotoxic payloads to tumor tissue and addressing the longstanding efficacy-toxicity trade-off in solid tumors.

Gülsah Nomak, MD, Medical Director of RS Research, stated: "The successful completion of the Phase 1 program provides the clinical foundation for our next stage of development. It supports our plans to advance RS-0139 into an international Phase 2 program designed to further define its therapeutic potential in solid tumors."

Dr. Sena Nomak, Co-Founder and COO of RS Research, added: "This milestone marks an important point of transition for RS Research as we move from early clinical validation toward broader international development. We have secured over 20 million USD backing so far from pharma, VC and non-dilutive funding sources. It strengthens our position in ongoing strategic discussions around the company’s global growth trajectory and comes at a meaningful time as we prepare for our upcoming Series B financing round."

The proceeds from the financing, which should fund the company into 2029, will be used to advance its lead candidate, STP-100, into multiple early-stage clinical studies, and to leverage its Pointillist Platform to identify additional tumor-specific cell surface epitopes enabling the development of additional pipeline candidates with a high therapeutic index.

"We are building upon deep cancer biology expertise to map, target and unlock tumor-specific epitopes which enable us to develop a pipeline of next-generation precision oncology therapeutics," said Jeff Landau, Chief Executive Officer of Stipple Bio. "This funding positions us to progress STP-100 into the clinic and continue building a broad oncology pipeline. I am extremely pleased to have the support of industry-leading investors who share our enthusiasm towards developing precision and differentiated cancer therapies based on our modality-agnostic Pointillist Platform."

"Clinical experience with prior antibody drugs has taught us that epitope-level specificity matters. Since the earliest days of Stipple Bio, we’ve been impressed by the team’s vision to move beyond tumor-specific gene expression and to pioneer tumor-specific ‘epitomics’ in precision oncology. We are proud to have supported Stipple Bio since inception and to co-lead this financing as the company advances safer, more effective therapies for patients living with cancer," said Dr. Agarwala, General Partner at Andreessen Horowitz and lead investor for the a16z Bio+Health Fund.

"Stipple Bio’s Pointillist Platform introduces an epitope-level approach to targeting tumor biology that has the potential to meaningfully expand the set of druggable oncology targets. Lead candidate STP-100 illustrates how this strategy can drive precise tumor targeting while sparing normal tissues—a key step toward improving therapeutic index in ADCs. We are excited to partner with the team as they advance STP-100 into the clinic and build a broader pipeline from the platform," said Dr. DiRocco, Partner at RA Capital Management.

Stipple Bio was founded in 2022 by cancer biology pioneers Dr. Aaron Ring, Associate Professor, Translational Science and Therapeutics Division at Fred Hutch, and Dr. Aashish Manglik, Associate Professor, Pharmaceutical Chemistry at UCSF, both of whom believed that targeting tumor-specific cell surface epitopes could improve therapeutic index and unlock targets previously intractable with conventional oncology drug discovery methods. a16z Bio+Health, Emerson Collective Investments (managed by Yosemite) and OMX provided Stipple Bio’s initial Seed financing.

Therapeutics Business Unit

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.
