Results From RMWC Funded Phase II Prostate Cancer Trial using INV043 – Strong Safety Profile and 40% Positive Response Rate

Invion Limited (ASX: IVX) (“Invion” or the “Company”) wishes to announce that RMW Cho Group Limited (RMWC), the licensor of the Photosoft™ technology, has successfully completed a Phase II prostate cancer trial1 (ACTRN12621000633886) using a sublingual (under the tongue) formulation of INV043, the same active pharmaceutical ingredient (API) in the topical formulation that Invion is using for its Phase I/II non-melanoma skin cancer trial.


Highlights:

  • RMW Cho Group Limited (RMWC) has provided Invion a report authored by Scendea detailing a recently completed investigator-led Phase II prostate cancer trial using the photosensitiser INV043
  • The trial results showed that INV043 administered sublingually (under the tongue) has a solid safety profile and demonstrated promising efficacy signals three months post treatment:
    • A regime of 6 cycles of INV043 treatments was very well tolerated by patients
    • No serious adverse events were experienced and all side effects reported were mild
    • 40% of patients showed a positive response as measured by the RECIST 1.1 standard (10% had complete response)
    • 44% of patients had negative PSMA-PET results 3 months post treatment
  • The positive safety and efficacy signals for INV043 opens the potential for treatment of prostate cancer without the serious side effects associated with conventional treatments
  • The safety data from the trial indicates potential for INV043 to be administered systemically in future clinical trials including via sublingual and IV routes
  • The global prostate cancer market is expected to grow to ~US$27.5 billion by 2032 (8.7% CAGR from 2023 to 2032)4
  • INV043 is the same active pharmaceutical ingredient that Invion is using in its Ph I/II skin cancer trial (topical formulation)

RMWC provided Invion with a clinical study summary report collated by Scendea Limited (Scendea) using information received and relied upon from RMWC based on the results of the investigator-led and open label trial that was fully funded by RMWC. Scendea is a leading pharmaceutical development and regulatory consulting group.

The Phase II prostate cancer trial used six treatment cycles of INV043 as a monotherapy. It was found to be safe and well tolerated by patients with no serious adverse events experienced and all side effects reported were mild.

In terms of efficacy signals, 40% of patients showed a positive response to the treatment with 10% demonstrating complete regression as measured by the Response Evaluation Criteria in Solid Tumours (RECIST) 1.1 framework – a standard way to measure the response of a tumour to treatment.

Further, 44% of patients had negative Prostate Specific Membrane Antigen – Positron Emission Tomography (PSMA-PET) results three months post treatment (all patients were positive before the treatment).

The report concluded that “the favourable safety profile and the preliminary efficacy results are promising and warrant further investigation of INV043”. Further details of the study are included in the sections below.

In contrast, radiotherapy, chemotherapy and surgery (which are currently mainstream treatment options) carry risks of significant side effects, such as urinary incontinence, bowel dysfunction, erectile dysfunction and /or infertility2. Due to these risks, the standard of care is to monitor the cancer until it progresses to a point where the benefits of these treatments outweigh the risks.

However, this approach may cause anxiety among patients who will have to live with the cancer without knowing if it will one day become more severe or even life-threatening.

Commenting on the results, Invion’s Executive Chair and Chief Executive Officer (CEO) Thian Chew said:

“It’s very exciting to see these results for our lead cancer candidate, INV043. The results showed that INV043 can be safely administered and activated with light to treat prostate cancer. It also highlighted its potential to be safely administered systemically to patients, including via sublingual and even IV routes.

“Together with the positive efficacy signals from this trial, this points to the prospect of INV043 to become an effective treatment for prostate cancer without the devastating side effects that can be associated with conventional treatments.”

Prostate cancer is the second most common cancer in men3. The global prostate cancer market is expected to grow to around US$27.5 billion by 2032, representing a compound annual growth rate (CAGR) of 8.7% over the forecast period from 2023 to 20324.

Invion’s patented lead Photosensitiser, INV043, was developed to preferentially target and accumulate in tumour cells, and not healthy cells. The trial design focused on the safety and efficacy of sublingually administrated INV043 as a monotherapy and the use of a laser probe to apply red light to the prostate/prostatic fossa using transurethral and/or transrectal intraluminal techniques.

On the back of these results, Invion is exploring opportunities to progress this program into a larger trial that may explore avenues to further improve response rates including combination therapies with immunotherapies, such as immune checkpoint inhibitors (ICIs). In vivo studies undertaken separately by the Peter MaCallum Cancer Centre and Hudson Institute of Medical Research found INV043 to dramatically improve the effectiveness of ICIs on various cancers5.

5 Biggest Pharmaceutical ETFs in 2025

The global pharmaceutical market reached a total value of US$1.38 trillion in 2024, according to Research and Markets, up significantly from the US$888 billion seen just over a decade earlier in 2010.

Experienced and novice investors alike may want to consider pharmaceutical exchange-traded funds (ETFs) as a way to gain exposure to the top pharma companies. Like all ETFs, pharmaceutical ETFs are a good option for those who want to trade a set of assets in the pharmaceutical industry instead of focusing solely on individual pharmaceutical stocks.

The main advantage of a pharmaceutical ETF is the fact that it can provide exposure to an overarching sector, but still trades like a stock. Pharma ETFs also offer less market volatility and lower fees and expenses.

Pfizer's Sasanlimab Combination Significantly Improves Event-Free Survival in BCG-Naïve, High-Risk Non-Muscle Invasive Bladder Cancer

  • Pivotal Phase 3 CREST trial results show a 32% reduction in the risk of disease-related events, including high-grade disease recurrence or progression, with sasanlimab in combination with standard of care (SOC) Bacillus Calmette-Guérin (BCG) regimen compared to SOC alone
  • Sasanlimab, a subcutaneously administered PD-1 inhibitor, in combination with BCG represents the first potential treatment advancement for BCG-naïve, high-risk non-muscle invasive bladder cancer in more than 30 years
  • Results have been shared with global health authorities to support potential regulatory filings

Pfizer Inc. (NYSE: PFE) today announced results from the pivotal Phase 3 CREST trial of sasanlimab, an investigational anti-PD-1 monoclonal antibody (mAb), in combination with standard of care (SOC) Bacillus Calmette-Guérin (BCG) as induction therapy with or without maintenance in patients with BCG-naïve, high-risk non-muscle invasive bladder cancer (NMIBC). The trial met its primary endpoint of event-free survival (EFS) by investigator assessment, demonstrating a clinically meaningful and statistically significant improvement with sasanlimab in combination with BCG (induction and maintenance) as compared to BCG alone (induction and maintenance): Hazard Ratio (HR) of 0.68; 95% Confidence Interval (CI), 0.49-0.94; 2-sided p=0.019; median EFS not yet reached. These findings show a 32% reduction in risk of disease-related events, including high-grade disease recurrence or progression, with the sasanlimab combination regimen as compared with SOC treatment alone. Pre-specified subgroup analyses for patients harboring higher risk disease showed consistent benefit with EFS HR of 0.63 (0.41, 0.96) for T1 disease, and EFS HR 0.53 (0.29, 0.98) for those with CIS disease.
