"CLIO-8221 is the first program from Callio’s dual-payload ADC pipeline to enter the clinic, just one year after our launch, underscoring our commitment to advancing innovative dual-payload ADCs for cancer. By combining two complementary anti-cancer payloads, CLIO-8221 may offer a new treatment option for patients whose cancers are resistant to existing single-payload Topo1 inhibitor-based ADCs," said Jerome Boyd-Kirkup, Ph.D., Chief Scientific Officer of Callio Therapeutics. "Our preclinical studies support the high potency and enhanced tolerability of CLIO-8221, enabled by our next generation linker platform and ADC technologies, and we look forward to presenting these data at AACR (Free AACR Whitepaper)."

At AACR (Free AACR Whitepaper) 2026, Callio Therapeutics will present data that highlight the potential of CLIO-8221 as a therapeutic option for HER2-expressing cancers:

CLIO-8221 is a dual-payload ADC carrying a Topo1 inhibitor and an ATR inhibitor (DAR 4:4 ratio), selected to maximize anti-tumor efficacy and overcome Topo1 inhibitor resistance
CLIO-8221 uses proprietary linker and ADC technologies to reduce systemic toxicity and enable co-delivery of both payloads to drive strong tumor cell killing
CLIO-8221 demonstrated potent anti-tumor activity across varying HER2 expression levels and drove tumor regression after a single dose in both trastuzumab deruxtecan-sensitive and -insensitive models
CLIO-8221 has a broad therapeutic window with no toxicological findings observed at doses up to 70 mg/kg in NHP studies
Poster Presentation:

Title: Development of CLIO-8221: A HER2-targeted dual-payload ADC to address ADC resistance
Session Title: Session PO.ET02.03 – Antibody-Drug Conjugates and Linker Engineering 3
Date & Time: April 21, 2026, 9:00 AM – 12:00 PM PDT
Location: Poster Section 12
Poster Board Number: 5
Poster Number: 4427

A Phase 1 clinical trial (NCT07300943) for CLIO-8221 is ongoing in Australia and the United States, with Callio Therapeutics having received IND clearance from the U.S. Food and Drug Administration in March 2026. The IND is also under review by the China National Medical Products Administration, and the trial is expected to expand to multiple sites in China.

About CLIO-8221

HER2 is a clinically validated target for antibody-drug conjugates (ADCs), with multiple approved therapies demonstrating meaningful benefit across tumor types, however, most patients eventually progress on treatment despite retaining HER2 expression. Mechanistic resistance to cytotoxic payloads has emerged as a key reason for treatment failure. CLIO-8221 is a novel, first-in-class dual-payload ADC targeting HER2, designed to address this challenge.

CLIO-8221 delivers two mechanistically complementary payloads, a topoisomerase 1 (Topo1) inhibitor and an ATR inhibitor, directly to HER2-expressing tumors. While Topo1 inhibitors have shown strong clinical activity, activation of the DNA damage response following Topo1 inhibitor-induced replication stress represents a potential major driver of resistance. By simultaneously inhibiting Topo1 and blocking the DNA damage response through ATR inhibition, CLIO-8221 is engineered to overcome payload insensitivity and sensitize tumors to Topo1 inhibition. Developed using proprietary linker and ADC platform technologies, CLIO-8221 aims to maximize anti-tumor activity while reducing systemic toxicity, offering the potential for deeper and more durable responses in patients who have progressed on existing HER2-targeted therapies.

Sonire’s proprietary High-Intensity Focused Ultrasound (HIFU) therapy system combines real-time imaging guidance with patented technologies, including a noise-cancellation system, cavitation bubble visualization, and a robot-assisted positioning platform, along with advanced capabilities such as rapid multi-focus scanning, to enable precise, effective thermal ablation of tumors. Unlike conventional ultrasound-guided HIFU systems, Sonire’s solution provides clear real-time visualization of the treatment site, requires no anesthesia, and can be performed on an outpatient basis in approximately 20 minutes. Additionally, this system requires only one physician to administer treatment, which lowers the cost and staff burden for hospitals.

"We are grateful for the strong support from our investors, which validates the transformative potential of our sonic technology," said Tohru Satoh, President and CEO of Sonire Therapeutics. "This funding enables us to complete our landmark SUNRISE-I randomized controlled trial in Japan, which will be the world’s first of its kind for HIFU in pancreatic cancer, while preparing for U.S. clinical and regulatory milestones. Our goal is to deliver a new standard of care that gives patients more time and better quality of life, without the burdens of invasive procedures or anesthesia."

Pancreatic cancer remains one of the most lethal diseases, with a 5-year survival rate of only 12%. Existing treatments are limited, and to date, there is the still high unmet medical needs due to a lack of established standard local therapy options. Sonire’s approach is designed to prolong overall survival when combined with chemotherapy while offering a safer, more patient-friendly alternative to surgery or radiation.

Foundational work from an academic-led study using a prototype HIFU system (MoonShot-2) demonstrated a 66% disease control rate in patients with advanced or refractory pancreatic and biliary tract cancers in a sonodynamic therapy (SDT) setting. These findings have informed the development of Sonire’s current system. The SUNRISE-I study (HIFU with chemotherapy vs. chemotherapy alone) is ongoing across seven leading Japanese hospitals with Sonire’s current system. The company holds 25 issued patents and 22 pending.

"Sonire has engineered a genuine leap forward in next generation HIFU by solving the core challenges of visualization, precision, and workflow that so far have limited the field," noted Dennis McWilliams, Managing Director for Santé. "Santé is excited to lead this round to expand Sonire’s corporate footprint to the United States and build upon their solid clinical foundation in Japan."

"Sonire’s differentiated approach is well positioned to bring meaningful benefit to patients globally. We look forward to continuing our support of the team as they advance U.S. clinical development" noted Koji Yasuda, Principal at Fast Track Initiative (FTI)
