Board of Directors approves quarterly cash dividend of $0.43 per share
Invion (ASX:IVX) is a clinical-stage Australian life sciences company pioneering the next generation of photodynamic therapy (PDT) for the treatment of cancer and infectious diseases. Invion is advancing a transformative approach to disease treatment and diagnosis with a platform grounded in preclinical promise and growing clinical validation.
At the core of Invion’s platform is Photosoft, a proprietary suite of next-generation photosensitizers that selectively accumulate in diseased cells. Upon light activation, these compounds trigger a targeted oxidative stress response, leading to cell death with high precision. Unlike traditional PDT agents, Photosoft compounds are engineered to overcome the limitations of toxicity, off-target damage, and limited immune engagement. They are designed to deliver enhanced safety, selectivity, immune system activation, and theragnostic capabilities.
Invion is strategically expanding its clinical and commercial footprint through non-dilutive global partnerships that accelerate development while preserving shareholder value. In South Korea, Hanlim Pharm is fully funding the preclinical development of Photosoft for two high-need indications: glioblastoma multiforme (GBM) — one of the most aggressive and treatment-resistant brain cancers — and oesophageal cancer. Under the terms of the partnership, Hanlim covers all development costs, while Invion retains full ownership of the underlying intellectual property, positioning the company to benefit from future global opportunities.
Company Highlights
- Clinical-stage Pipeline in Multiple Indications: Successfully completed Phase II prostate cancer trial, ongoing Phase I/II skin cancer trial, and anogenital cancer trial initiating in 2025. Multiple cancer and infectious disease programs underway.
- Photosoft Platform Technology: Combines cancer selectivity, immune system activation, and minimal toxicity. Preclinical studies show INV043 can regress multiple cancers, deliver superior safety and efficacy and improve tumour control to 80 percent in combination therapy studies with blockbuster ICIs (vs 12 percent with ICIs alone).
- Renowned Partners & Global Pharma-funded Collaborations: Working with distinguished research institutions like Peter MacCallum Cancer Centre and Hudson Institute of Medical Research. Further, Hanlim Pharm (GBM, oesophageal cancer) and Dr.inB (HPV) are funding multiple programs without requiring Invion to contribute capital or give up IP.
- Theragnostic Capability: Photosoft compounds enable both treatment and imaging, allowing for highly precise cancer targeting and enhanced surgical decision-making.
- Strong Clinical and IP Foundation: GMP-grade INV043 manufactured and patented in Australia, with global IP protection extending to at least 2041.
- Compelling Upside: Following a share consolidation and reduced overhangs, IVX offers significant re-rating potential with multiple clinical readouts expected over the next six to 12 months.

Investor Insight
With a strong IP portfolio, deep clinical-stage pipeline, global collaborations and an experienced leadership team, Invion is poised for transformative value creation as it enters the next phase of clinical and commercial growth.
Overview
Invion Limited (ASX:IVX) is a clinical-stage Australian life sciences company focused on transforming photodynamic therapy (PDT) into a next-generation solution for treating cancer and infectious diseases. The company’s core value lies not just in preclinical promise, but in real-world clinical validation.
At the heart of Invion’s platform is Photosoft, a proprietary suite of next-generation photosensitizers that selectively target diseased cells and, upon light activation, induce a precise oxidative stress response to destroy them. Unlike conventional PDTs that suffer from toxicity and off-target effects, Photosoft compounds are engineered for enhanced safety, specificity, immune activation, and theragnostic utility. INV043, Invion’s lead cancer drug candidate, has demonstrated up to 80 percent tumor control in combination with immune checkpoint inhibitors, and is now in human trials.The company is actively progressing a broad pipeline across multiple indications, including:
- A Phase I/II trial in non-melanoma skin cancer (NMSC), now dosing in Australia
- An anogenital cancer trial in collaboration with Peter MacCallum Cancer Centre, scheduled to begin in 2025
- A completed investigator-led Phase II prostate cancer trial, showing a 40 to 44 percent response rate with a strong safety profile
These trials signal a critical shift for Invion from preclinical research to meaningful clinical validation, spanning both systemic and topical formulations. The safety data from the NMSC trial is expected to support accelerated development of the anogenital cancer program, given both use the same topical compound.
The clinical results so far have been consistent with the findings from the preclinical studies – showing INV043 to be very safe with promising efficacy signals. The next set of trials aim to further solidify the potential for the technology, where the one drug can treat multiple cancers, improve patient outcomes when using checkpoint inhibitors in combination with INV043 and demonstrate its diagnostic and theragnostic potential.
Beyond internally funded trials, Invion is strategically expanding its clinical and commercial footprint through non-dilutive, global partnerships. In South Korea, Hanlim Pharm is funding the preclinical development of Photosoft for glioblastoma multiforme — a highly aggressive brain cancer — and oesophageal cancer, both of which present major unmet needs. These programs are fully financed by Hanlim, with Invion retaining all intellectual property
Similarly, Dr. I&B Co. (Dr.inB), another South Korean group, is backing the development of Photosoft for human papillomavirus (HPV) in a new proof-of-concept trial. This collaboration not only funds a novel therapeutic area outside of oncology but underscores the versatility of Photosoft as a multi-indication, platform technology. Invion bears none of the clinical trial costs and maintains all rights to future commercialization.
In parallel, Invion is expanding the Photosoft platform into infectious diseases, where preclinical studies have demonstrated broad-spectrum antimicrobial activity. The compound has proven effective in vitro against:
- Antibiotic-resistant “superbugs”
- Fungal and bacterial infections
- SARS-CoV-2 (Omicron)
- Oral and periodontal conditions such as peri-implant mucositis
These results reflect Invion’s long-term vision of developing a scalable, accessible and affordable therapy platform that addresses both high-burden cancers and the growing global threat of antimicrobial resistance. With Photosoft, the company is building a foundation not just for treating disease — but for reshaping therapeutic accessibility and patient outcomes worldwide.

Key Programs
Non-melanoma Skin Cancer
Invion’s leading active trial is a Phase I/II adaptive clinical study targeting non-melanoma skin cancer — a condition that represents 98 percent of all skin cancers and constitutes a substantial public health burden in Australia. Using a topical formulation of INV043, the trial is designed with a 3+3 structure allowing real-time protocol optimization for safety and efficacy. The formulation offers significant cosmetic and pain-reduction benefits over existing approved PDT treatments like Metvix (by Galderma S.A.) and excisional surgery, both of which have limitations related to scarring and pain. Dosing of the first patient commenced in December 2024, with ongoing recruitment and interim data expected in the second half 2025 or early 2026. The skin cancer program not only represents a potentially fast path to market but also supports downstream programs, such as the anogenital cancer study, through shared formulation and safety data.
Anogenital Cancers (Peter Mac Collaboration)
The anogenital cancer program is a major upcoming milestone for Invion, developed in collaboration with the prestigious Peter MacCallum Cancer Centre in Melbourne, Australia, one of the leading oncology research centres in the world. Utilizing the same topical INV043 formulation as the non-melanoma skin cancer trial, this Phase I/II study will leverage safety data from the trial to accelerate approval timelines. The anogenital trial targets high-risk lesions and cancers with limited therapeutic options, and benefits from the scientific and operational expertise of Peter Mac. Preclinical data showed exceptional synergy when INV043 was used in combination with immune checkpoint inhibitors (anti-PD-1), achieving up to 80 percent tumor-free responses in models of anal squamous cell carcinoma, compared with a circa 12 percent response rate with aniti-PD-1 alone. This program exemplifies Invion’s theragnostic strength, where the compound also enables fluorescent visualization of tumor margins to aid surgical decision-making.
Prostate Cancer (Phase II Completed)
INV043 has completed a Phase II investigator-led clinical trial in prostate cancer, funded by the RMW Cho Group. The trial involved sublingual systemic administration of the compound followed by targeted light therapy. Following COVID-related disruptions, a second cohort of 16 patients was successfully treated and evaluated using PSMA-PET scans and RECIST criteria. Results were compelling: 44 percent of patients showed no detectable cancer via PSMA-PET scan three months post-treatment, while 40 percent demonstrated partial or stable response by MRI. The therapy was extremely well-tolerated, with no serious adverse events and only mild treatment-emergent side effects. These findings serve as clinical proof-of-concept for systemic delivery of INV043, highlighting its potential for deeper-seated cancers and reinforcing its safety and scalability.
Glioblastoma and Oesophageal Cancer (Hanlim Pharma Collaboration)
Through a strategic partnership with South Korean pharmaceutical company Hanlim Pharma, Invion is advancing preclinical programs for two highly aggressive and deadly cancers: glioblastoma multiforme and oesophageal cancer. Hanlim is funding both programs entirely, allowing Invion to retain all IP and avoid capital outlay. These programs are exploring INV043’s efficacy in some of the most treatment-resistant solid tumors, with early-stage studies underway and updates expected in 2025. If successful, this collaboration could lead to regional licensing or joint ventures in Asia, significantly expanding Invion’s global footprint.
HPV and Infectious Diseases (Dr.inB Collaboration)
Dr.inB, a leading PDT innovator in South Korea, is partnering with Invion to develop Photosoft-based treatments for HPV-related conditions, including genital warts and potentially HPV-linked cancers. The program, which includes proof-of-concept human trials, is entirely funded by Dr.inB, and Invion retains all IP and commercialization rights. Beyond HPV, Photosoft has demonstrated broad-spectrum antimicrobial potential against antibiotic-resistant bacteria, fungi and viruses, including SARS-CoV-2. This opens the door to applications in periodontal disease, peri-implant mucositis, and other infectious conditions. PDT’s unique mechanism of action — using light to generate oxidative stress — renders it immune to resistance development, making it an ideal candidate for combatting antimicrobial resistance, one of the top 10 threats to humanity identified by the World Health Organization.

ACIP Votes to Expand Recommendation for Pfizer's RSV Vaccine ABRYSVO® to Include Adults Aged 50 to 59 at Increased Risk of Disease
- Vote expands existing recommendation, which was for all adults aged 75 and older and high-risk adults aged 60 to 74
Pfizer Inc. (NYSE: PFE) announced today that the U.S. Centers for Disease Control and Prevention's (CDC) Advisory Committee on Immunization Practices (ACIP) voted to expand its recommendation for the use of respiratory syncytial virus (RSV) vaccines approved for adults 50-59 years of age at increased risk of RSV-associated lower respiratory tract disease (LRTD). This includes ABRYSVO ® (Respiratory Syncytial Virus Vaccine), which in October 2024, the U.S. Food and Drug Administration approved for the prevention of RSV-associated LRTD in adults aged 18 to 59 at increased risk of severe disease.
According to the CDC, between 15,000 - 20,000 RSV-associated hospitalizations occur annually in U.S. adults aged 50 - 59 years. 1 The risk of hospitalization is highest among those adults with one or more underlying medical conditions such as obesity, cardiovascular disease, diabetes, chronic obstructive pulmonary disorder (COPD), asthma, and other chronic or immunocompromising conditions. 1 With respect to ABRYSVO, ACIP stated:
- ACIP recommends adults 50–59 years of age who are at increased risk of severe RSV disease receive a single dose of RSV vaccine.
"With its vote to expand adult RSV vaccination recommendations, ACIP has taken an important step toward protecting individuals aged 50 to 59 who have underlying medical conditions that increase their risk for severe RSV illness," said Alejandro Cane, Vice President, Vaccines and Antivirals U.S. Medical Lead, Pfizer. "We are proud that ABRYSVO has the broadest indication among RSV vaccines, covering older adults, adults 18 and older at heightened risk of severe disease, and pregnant women to help protect infants."
The updated ACIP recommendation, which lowers the recommended age for RSV vaccination from 60 to 50 for high-risk adults, is pending final approval by the director of the CDC and the Department of Health and Human Services.
ABOUT RSV
Respiratory syncytial virus (RSV) is a contagious virus and a common cause of respiratory illness. 2 The virus can affect the lungs and breathing passages of an infected individual, potentially causing severe illness or death. 3,4 Chronic cardiovascular disease, chronic lung disease, moderate or severe immune compromise, diabetes with complications, and severe obesity are among the conditions that increase an individual's risk for severe RSV. 5 There are two major subgroups of RSV: RSV-A and RSV-B. Both subgroups cause disease and can co-circulate or alternate predominance from season to season.
ABOUT ABRYSVO
Pfizer currently is the only company with an RSV vaccine to help protect adults aged 60 and older, and adults 18 and older at increased risk of lower respiratory tract disease caused by RSV (RSV-LRTD), as well as infants through maternal immunization. ABRYSVO is an unadjuvanted, bivalent vaccine that was designed to provide broad protection against RSV-LRTD, regardless of the virus subgroup. In the prefusion state, the RSV fusion protein (F) is a major target of neutralizing antibodies, serving as the basis of Pfizer's RSV vaccine. Variations in the F protein sequence among RSV-A and RSV-B subgroups are clustered in a key antigenic site, a target for potent neutralizing antibodies.
In May 2023, the FDA approved ABRYSVO for the prevention of LRTD caused by RSV in individuals 60 years of age or older. In June 2024, the Advisory Committee on Immunization Practices (ACIP) voted to update its recommendation of RSV vaccines for use in adults aged ≥75 years and adults age 60-74 years who are increased risk for severe RSV disease. In August 2023, the FDA approved ABRYSVO for the prevention of LRTD and severe LRTD caused by RSV in infants from birth up to 6 months of age by active immunization of pregnant individuals at 32 through 36 weeks gestational age. This was followed in September 2023 with ACIP's recommendation for maternal immunization to help protect newborns from RSV seasonally where the vaccine should be administered from September through January in most of the continental United States.
Also in August 2023, Pfizer announced that the European Commission granted marketing authorization for ABRYSVO for both older adults and maternal immunization to help protect infants, and in March 2025 announced the amended marketing authorization to extend the indication to include a broader adult population. Additionally, ABRYSVO has received approvals for both indications in multiple countries worldwide.
INDICATIONS FOR ABRYSVO
ABRYSVO ® is a vaccine indicated in the U.S. for:
- the prevention of lower respiratory tract disease (LRTD) caused by respiratory syncytial virus (RSV) in people 60 years of age and older
- the prevention of LRTD caused by RSV in people 18 through 59 years of age who are at increased risk for LRTD caused by RSV
- pregnant individuals at 32 through 36 weeks gestational age for the prevention of LRTD and severe LRTD caused by RSV in infants from birth through 6 months of age
IMPORTANT SAFETY INFORMATION FOR ABRYSVO
- ABRYSVO should not be given to anyone with a history of severe allergic reaction (e.g., anaphylaxis) to any of its components
- An increased risk of Guillain-Barré syndrome (severe muscle weakness) was observed after vaccination with ABRYSVO
- For pregnant individuals: to avoid the potential risk of preterm birth, ABRYSVO should be given during 32 through 36 weeks gestational age
- Fainting can happen after getting injectable vaccines, including ABRYSVO. Precautions should be taken to avoid falling and injury during fainting
- Adults with weakened immune systems, including those receiving medicines that suppress the immune system, may have a reduced immune response to ABRYSVO
- Vaccination with ABRYSVO may not protect all people
- In adults 60 years of age and older, the most common side effects (≥10%) were fatigue, headache, pain at the injection site, and muscle pain
- In adults 18 through 59 years of age, the most common side effects (≥10%) were pain at the injection site, muscle pain, joint pain and nausea
- In pregnant individuals, the most common side effects (≥10%) were pain at the injection site, headache, muscle pain, and nausea
- In clinical trials where ABRYSVO was compared to placebo, infants born to pregnant individuals experienced low birth weight (5.1% ABRYSVO versus 4.4% placebo) and jaundice (7.2% ABRYSVO versus 6.7% placebo)

Pfizer Provides Update on Oral GLP-1 Receptor Agonist Danuglipron
Pfizer Inc. (NYSE: PFE) today announced the decision to discontinue development of danuglipron (PF-06882961), an oral glucagon-like peptide-1 (GLP-1) receptor agonist, which was being investigated for chronic weight management.
Pfizer's dose-optimization studies of once-daily formulations of danuglipron ( NCT06567327 and NCT06568731 ) met key pharmacokinetic objectives and confirmed a formulation and dose with the potential to deliver a competitive efficacy and tolerability profile in Phase 3 testing, based on earlier studies of twice-daily danuglipron. While the overall frequency of liver enzyme elevations across the over 1,400 participant safety database of danuglipron is in-line with approved agents in the class, a single asymptomatic participant in one of the dose-optimization studies experienced potential drug-induced liver injury which resolved after discontinuation of danuglipron. After a review of the totality of information, including all clinical data generated to date for danuglipron and recent input from regulators, Pfizer has decided to discontinue development of the molecule.
"Cardiovascular and metabolic diseases including obesity remain important areas of unmet medical need, and we plan to continue applying our global capabilities to advance a pipeline of investigational treatments that have the potential to fill critical gaps in patient care, including continued development of our oral GIPR antagonist candidate and other earlier obesity programs," said Chris Boshoff, MD, PhD, Chief Scientific Officer and President, Research and Development at Pfizer. "While we are disappointed to discontinue the development of danuglipron, we remain committed to evaluating and advancing promising programs in an effort to bring innovative new medicines to patients."
Data from the danuglipron clinical development program will be presented at a scientific forum or submitted for publication in a peer-reviewed journal in the future.
