Radiopharm Theranostics Doses First Patient in Phase 1 'HEAT' Trial of 177Lu-RAD202 for Treatment of Advanced HER2-Positive Solid Tumors

Radiopharm Theranostics Doses First Patient in Phase 1 'HEAT' Trial of 177Lu-RAD202 for Treatment of Advanced HER2-Positive Solid Tumors

 

   Phase 1    1   First-In-Human study designed to assess safety   ,   tolerability   , right dose for Phase 2 and early signs of efficacy   of 177Lu-RAD20   2   in individuals with   advanced HER2-positive solid   tumors  

 

  Previous clinical proof-of concept data   2   for targeting HER-2 demonstrated the safety and biodistribution of 99mTc-RAD202 in humans  

 

Radiopharm Theranostics (ASX:RAD, "Radiopharm" or the "Company"), a clinical-stage biopharmaceutical company focused on developing innovative oncology radiopharmaceuticals for areas of high unmet medical need, today announced the dosing of the first patient in its Phase 1 ‘HEAT' clinical trial of RAD202, a proprietary nanobody that targets Human Epidermal Growth Factor Receptor 2 (HER2)-positive expression in a wide array of advanced solid tumors.

 

The open-label Phase 1 "HEAT' clinical trial is a dose escalation trial of 177Lu-RAD202 that is designed to determine the recommended Phase 2 dose and to evaluate the safety and preliminary clinical activity of this novel radiotherapeutic in individuals with HER2-expressing advanced cancers. The study is currently being conducted at clinical centers across Australia.

 

"Dosing patients in the HEAT clinical trial marks an important milestone in our transition to a clinical-stage company," said Riccardo Canevari, CEO and Managing Director of Radiopharm Theranostics. "Despite progressive improvements in the management of metastatic HER2-positive disease, the majority of patients experience disease progression on current standard of care and require further therapeutic options. The dosing of the first patient in the ‘HEAT' trial represents a significant step toward achieving RAD202's potential to address an unmet need for HER2-positive metastatic patients who are progressing or unable to tolerate current treatment options. With RAD202, we hope to provide an option that can meaningfully improve clinical outcomes for HER2-positive patients, while preserving their quality of life."

 

HER2 is overexpressed in breast cancer as well as several other solid tumors and represents a validated target in oncology. RAD202 is a proprietary single domain antibody that targets HER2. Ten HER2-positive breast cancer patients previously dosed in a Phase 1 diagnostic study of RAD202 demonstrated clinical proof-of concept as well as the safety and biodistribution of RAD202, validating its potential for the treatment of advanced HER2-expressing cancers 2 .   Preclinical findings 3 examining the therapeutic effect in HER2-positive xenografts were also recently reported with 177Lu-RAD202. Collectively, these data further justify first in humans dose finding studies.

 

"It is a privilege to be the first centre to administer 177Lu-RAD202, targeting HER2-positive tumors in this Phase 1 clinical trial (HEAT)." said Dr Aviral Singh, Clinical Head of Theranostics and Nuclear Medicine at St John of God Murdoch Hospital. "This opens the possibility of novel therapeutic avenues for patients with aggressive tumor types, including breast, ovarian, gastric, pancreatic, bladder, and several other cancers. With the trust put in us by Radiopharm, we look forward to a successful trial with beneficial outcomes for our patients."

5 Small-cap Biotech ETFs to Watch

Thanks to exchange-traded funds (ETFs), investors don’t have to be tied to one specific stock. When it comes to biotech ETFs, they give sector participants exposure to many biotech companies via one vehicle.

ETFs are a popular choice as they allow investors to enter the market more safely compared to investing in standalone stocks. A key advantage is that even if one company in the ETF takes a hit, the impact will be less direct.

Below the Investing News Network takes a look at five small-cap biotech ETFs. The funds were selected using ETFdb.com, and only ETFs with total assets under management (AUM) under US$100 million as of June 30, 2025, were considered.

Inside the ASX Biotech Boom: What’s Fuelling the Next Wave

Australia’s healthcare and biotechnology sector has matured into one of the most promising and strategically important segments of the ASX. Fortunes can shift on a single clinical trial result. A company with no revenue today could be a global contender tomorrow — if its science holds up.

As investors sift through early stage biotech companies, the challenge is less about spotting ambition and more about recognising the markers of real-world impact: a strong intellectual property (IP) moat, well-timed milestones, non-toxic innovation and enough capital to get through the next inflection point. In a market where data can drive value faster than sales, understanding the rhythm of biotech development has become not just useful, but essential.

According to Australian market analyst firm Morgans, healthcare stocks have consistently delivered strong performances on the ASX over the last 10 years. With more than $8 billion in annual revenue, the Australian life science ecosystem is expected to continue to grow at an annual rate of 3 percent up to 2026.

Top 4 Small-cap ASX Biotech Stocks of 2025

The global biotechnology sector is on track to become a multi-trillion dollar industry.

Worldwide, the biotech space was worth an estimated US$1.68 trillion last year, according to Cervicorn Consulting. That value is expected to grow at a compound annual growth rate of 9.18 percent through 2033 to become a US$3.54 trillion market.

The major factors driving this growth are a strong clinical pipeline of precision medicine and regenerative technologies, as well as a rising demand for treatments for chronic diseases such as cancer, diabetes and neurological disorders.
