New dawn for NeuroScientific with stem cell acquisition
Stem cell therapies have long promised to press the body's reset button - potentially reversing injuries and damage from disease, regenerating tissue and reshaping modern medicine. For ASX-listed NeuroScientific Biopharmaceuticals, that promise starts now thanks to its $5.1 million acquisition of unlisted Perth-based stem cell therapy company Isopogen.
The deal will hand NeuroScientific the keys to Isopogen's patented 'StemSmart' technology, which innovatively prepares a specific type of stem cell, mesenchymal stem cells (MSC), for use as an intravenous infusion. MSC are universal donor cells, meaning that there is no need for matching between a donor and recipient. They are effectively an 'off-the shelf' cell therapy.
Over the past 20 years, haematology medical scientist Dr Marian Sturm, NeuroScientific's incoming chief scientific officer, pioneered the development of MSCs in her former role as facility director of Royal Perth Hospital's Cell and Tissue Therapies centre.
The cells have so far been used in many patients, including as a last-line treatment for critically ill patients suffering severe immune complications from bone marrow transplantation and in kidney and lung transplant rejection, through early phase clinical trials and studies and on compassionate grounds, with promising results.
The MSC technology has also been employed to treat patients with severe Crohn's disease, an inflammatory autoimmune condition that affects the gut. The disease can develop into very difficult-to-manage and treat forms, including refractory Crohn's, in which patients experience persistent uncontrolled flare-ups, and fistulising Crohn's, in which patients develop an open wound from a gut flare-up out to the skin.
'NSB's acquisition of Isopogen will allow our StemSmart technology to be progressed for the benefit of vulnerable patients with limited treatment options.'
NeuroScientific Biopharmaceuticals incoming chairman Robert McKenzie
In a phase two trial targeting refractory Crohn's disease, a condition that no longer responds to standard treatments, of 18 patients treated with StemSmart MSC, 78 per cent of patients experienced clinical improvement and 44 per cent achieved full remission. That level of efficacy is considered impressive in the MSC field, particularly for refractory Crohn's.
With the global market for refractory Crohn's treatment alone estimated to be worth about US$7.5 billion, it's no wonder StemSmart's new owner quickly hailed the system as a potential game-changer.
StemSmart technology offers a step up from traditional MSC manufacturing in that the cells are grown in a special media, becoming activated in the process. The platform technology was developed at Royal Perth Hospital (RPH) and manufactured using RPH's processes.

Aussie masseuse bans men after repeated inappropriate behaviour
An Australian masseuse has banned male clients from her studio after repeated inappropriate requests and comments from current and prospective male clients. Kessley Ham, 39, the owner of Eternal Energy Healing and Wellness in South Perth, told that moving forward, her business will only serve women, including trans women and non-binary clients. It all started earlier this week when she was venting to two of her team members about the 'relentless' stream of inappropriate booking requests she had received online. She said requests for 'sensual' or nude massages were common, despite it being clear on the studio's website and Instagram that it's not that kind of business. 'To my shock, both staff then shared their own experiences of inappropriate behaviour from clients in our studio,' she said. The decision to ban male clients Some of these incidents included a male client groaning on the massage table and 'writhing' around, 'orgasm-style', and another person who wanted to discuss their sex life with the masseuse. Another involved a male client repeatedly commenting that his underwear was 'uncomfortable and twisted' during the massage. 'That was the moment I knew I had to take action. My team's safety is non-negotiable. No one should feel unsafe or uncomfortable in their workplace — especially in a space dedicated to healing,' she said. The need for women-only spaces She chose not to pursue other approaches to combat the lewd behaviour – as 'this wasn't about business strategy' or retaining clients, but a pressing safety issue. 'Women deserve spaces where they can fully relax, physically, emotionally, and energetically, without being on high alert,' Ms Ham said. 'Unfortunately, the reality is that the biggest threat to a woman's safety continues to be men. That's not an opinion, it's a fact. Women-only spaces offer something rare: a full nervous system exhale.' Overwhelming support After sharing the news on her Instagram account, Ms Ham said the response has been overwhelmingly positive from women. 'I feel so sad for your staff … how unfortunate they had to encounter this. Well done for looking after them,' read one comment on the post. 'This is shocking to read,' said another. 'Power to you'. However, there have been a few predictable reactions from men who take issue with the change. Some women have even used the 'not all men' argument, suggesting Ms Ham should run her business on a 'recommendation' policy so the 'good men' can still come. Media 'redirecting' the narrative One media outlet apparently derailed an interview with Ms Ham about her decision by suggesting that this issue highlights 'how hard it is for men to find a massage that doesn't offer sexual services'. But Ms Ham emphasises that this isn't the issue here. 'The issue is the inappropriate and unsafe behaviour directed at women — including myself and my staff — in what should be a professional, therapeutic setting,' she noted. 'Redirecting the narrative to men's discomfort only highlights the need for women-only spaces even more.'

That level of efficacy is considered impressive in the MSC field, particularly for refractory Crohn's. With the global market for refractory Crohn's treatment alone estimated to be worth about US$7.5 billion, it's no wonder StemSmart's new owner quickly hailed the system as a potential game-changer. StemSmart technology offers a step up from traditional MSC manufacturing in that the cells are grown in a special media, becoming activated in the process. The platform technology was developed at Royal Perth Hospital (RPH) and manufactured using RPH's processes. Notably, the manufacturing methodology can yield more than 200 cryopreserved clinical doses from just 10 millilitres of precious donated bone marrow, giving it both clinical flexibility and manufacturing scale. Based on the early results in Crohn's disease and in other conditions, Sturm now sees hope in employing MSCs to treat other autoimmune and inflammatory diseases, possibly including lupus, multiple sclerosis and rheumatoid arthritis. As the cells can grow into skin, bone, fat and other tissue cells, they also offer potential applications for tissue repair, such as bone repair for skull or long bone injuries, for example. The clinical development of MSC stretches back to 2002, when a Swedish paediatric haematologist used MSCs for the first time to treat a child gravely ill with complications from the treatment of leukaemia. The cells were isolated and grown in the doctor's laboratory from bone marrow donated by the child's mother. The child's clinical response to the cells was striking. No doubt, the successful experimental treatment would have caught the attention of immunology and haematology researchers and clinicians worldwide, including Sturm, an expert in blood, cell and tissue transplant manufacturing for clinical applications, who was the then-director of RPH's cutting-edge Cell and Tissue Therapy facility. At the time, Sturm was particularly focused on delivering MSCs as safely as possible into healthcare areas of unmet need. She began experimenting with ways to process the cells into a safe infusion that could be used to treat diseases and transplant complications where there were few or no existing clinical options. In 2007, Dr Sturm was approached by her clinical colleagues, who wanted to use the MSC product on compassionate grounds to treat a critically ill man with complications of bone marrow transplant to treat blood cancer. At the time, about 60 per cent of bone marrow transplant patients, who received donor marrow, developed a serious complication, known as graft-versus-host disease (GVHD), where the new blood system created by the bone marrow transplant rejects the recipient's body. It usually presents with symptoms that affect the gut, skin and liver, and is treated with steroids. With recent advancements in transplant practices, the incidence of acute GVHD has fallen to now occurring in about 25-30 per cent of cases. However, these medicines fail in about 30 per cent of acute GVHD cases – and most of this group die. After receiving MSC treatment, the man quickly recovered, spurring Sturm to keep working to develop a scalable, commercial-grade MSC product and patenting the manufacturing process. After an agreement was reached between Isopogen and the State Government's East Metropolitan Health Service (EMHS) giving Isopogen control of the MSC technology, NeuroScientific struck a deal with Isopogen to progress StemSmart. The all-scrip acquisition sees Isopogen shareholders receive 85.7 million NeuroScientific shares and 57.1 million performance shares tied to future clinical and commercial milestones. The market welcomed the move, with NeuroScientific's share price surging 97 per cent on the day of the announcement. A $3.5 million capital raise led by Perth corporate advisor Westar Capital, after existing funds, creates a war chest of about $7.5 million. This will support further development, including for a special access program or bigger phase 2/3 trials for patients with refractory and fistulising Crohn's, and will enable regulatory engagement with Australia's Therapeutic Goods Administration with a long-term goal of partial or full registration for StemSmart MSC, first up as a Crohn's treatment. The company is also eyeing the United States, where inflammatory bowel disease is forecast to grow into a lucrative US$13.8 billion market by 2026. About 30 per cent of Crohn's patients fail to respond to current gold-standard treatments, such as biologics, making them prime candidates for a new approach, such as StemSmart. The takeover signals a bold pivot for NeuroScientific, which previously focused on peptide-based drugs for neurodegenerative diseases such as Alzheimer's. Those drugs showed promise, but the timelines to market were long. By contrast, StemSmart's progress and results over decades of development position the product closer to near-term commercialisation, helped along by NeuroScientific's healthy bank balance. Nor will NeuroScientific be walking away from its roots completely. Two current directors will remain on the company's revamped board, and management will explore crossover applications for StemSmart, particularly to tackle the neuroinflammation that is a hallmark of inflammatory diseases such as Alzheimer's. That convergence could open a dual-front therapeutic pipeline, leveraging both peptide and cellular approaches. While competition in the stem cell space is fierce, the upside is enormous. Importantly, the US Food and Drug Administration (FDA) recently approved the first mesenchymal stromal cell therapy by ASX-listed, regenerative medicine company Mesoblast. While MSC products have been approved in other jurisdictions, the FDA approval of an allogeneic, bone marrow-derived MSC product for paediatric, steroid-refractory, acute graft-versus-host disease is momentous. According to NeuroScientific, StemSmart is differentiated by its purity, potency and consistency. In preclinical and early human data, the platform has shown enhanced potency over conventional MSCs. The recent regulatory FDA approval of MSC also tilt the momentum in StemSmart's favour, suggesting regulators are warming to well-characterised stem cell platforms with rigorous clinical data.
