TGA approves Eli Lilly drug Kisunla in boost for dementia patients
The Therapeutic Goods Administration has approved a new drug tipped to revolutionise the treatment of hundreds of thousands of Australians suffering through early-stage Alzheimer's disease.
The breakthrough therapy called Kisunla, also known as donanemab, is designed to slow cognitive decline in patients by clearing amyloid plaques from the brain.
Frank Freschi, 77, from Melbourne, took the treatment as part of a clinical trial and said he hoped the drug could give him more time to enjoy with his grandchildren.
'I used to be able to remember lots of things, now I can remember what I did 40 years ago but not what I did 40 hours ago,' he said.
'Accessing an amyloid targeting therapy has meant holding onto the hope that I'm a little bit in control of my life, of what's happening to me.
'I'm also hoping that one day I will have helped medical science to produce a drug that will work for many people.
'And, selfishly, that I too may be able to get some more time out of it to enjoy with my family and my six grandkids.'
The TGA approved the drug, produced by US pharmaceutical behemoth Eli Lilly, on Wednesday, marking the first new treatment for early Alzheimer's disease in 25 years.
Alzheimer's is a fatal neurodegenerative disease and the most common cause of dementia, which impacts about 600,000 Australians directly and a further 1.7 million carers.
The economic impact of dementia from Alzheimer's was calculated at $8.1bn in 2024, with the figure expected to double by 2050.
The excessive build-up of amyloid plaques in the brain disrupts the brain's neurons and prevents messages from travelling normally, leading to memory and thinking issues.
Professor Peter Gonski, a Sydney-based geriatrician and Alzheimer's specialist, told NewsWire the treatment could potentially give two years back to patients.
'For those starting to deteriorate, it will give them an extra couple of years in benefit in those that do well on it,' he said.
'You're getting a better start in your dementia history.'
Professor Gonski stressed, however, the treatment could slow decline but would not cure the disease.
'When it gets to moderate or severe, it's not going to make a lot of difference, except that you have had that extra time when you were better,' he said.
Patients receive an intravenous injection of the drug once every four weeks.
Dementia Australia chief executive Tanya Buchanan said the TGA's approval marked a 'step forward' in dementia treatment, but the treatment would only impact a select profile of patients.
'With dementia the second leading cause of death of Australians and the leading cause of death of Australian women, we welcome any steps taken towards improving the lives of people living with dementia, their families and carers,' Professor Buchanan said.
'It is important to note that donanemab does come with possible side effects that needs to be carefully communicated to patients so they can make an informed choice and the treatment needs to be monitored by health professionals.
'We also need to ensure people understand that donanemab is not a cure and is only suitable for people in the early stages of Alzheimer's disease with a defined genetic profile, which is why it is so important for people to receive a timely diagnosis.'
Eli Lilly, a $1 trillion company listed on the New York Stock Exchange, will apply for donanemab to be included on the Pharmaceutical Benefits Scheme, with an advisory committee hearing expected in July.

Dad dies in cruise horror, sick response for pleas to help
When Chloe Moloney launched a public appeal to help get her gravelly ill dad home, she didn't expect to cop a barrage of hate from online trolls. Random strangers telling her if her dad could afford to go on a cruise, he could afford the $14,000 it would take to fly home with a dedicated nurse after he suffered a brain bleed and underwent two high-risk surgeries. 'Stop your whining, it's their own fault for travelling without travel insurance' one commentator wrote. 'People with cancer have to pay for transfers so why wouldn't you' and 'why should taxpayers have to pay to get your dad home?'. Chloe was shocked by the response. 'Why are people so horrible? I've lost faith in all of humanity,' she said. But she put the negativity behind her and continued her plight to bring her dad home from Darwin to Western Australia. Her beloved dad Peter Jackson couldn't hang on any longer. Despite the best efforts of medical staff, he died on Friday. 'Unfortunately, we have had some bad news today. Dad had another bleed, and a cardiac arrest, and has been placed on life support,' Chloe said on Friday. 'There's nothing else they can do for him. Mum and I are flying up tomorrow to say our goodbyes and turn off his life support. 'I'll fight tooth and nail to get his story out there and how the system failed him.' What started out as a fun-filled holiday turned into tragedy for Peter and his wife Amanda. They set sail from Sydney to Fremantle on the Crown Princess and were having the time of their lives celebrating their 40th wedding anniversary until 63-year-old Mr Jackson fell backwards while re-embarking the vessel after ANZAC celebrations in Darwin. He suffered a bleed on the brain and was rushed to the ship hospital - but when the captain decided the ship had to set sail Mr Jackson was taken to Royal Darwin Hospital where he has since undergone two surgeries for brain bleeds. 'He was unconscious for two days and we were told he was in trouble, and to prepare ourselves,' Ms Moloney told at the time. 'We were told Dad was too unwell to be transported and he needed to be stable for an airlift. Once he was stable, an airlift was to be done. Dad came around and improved and was moved to a ward.' But for reasons unknown to the anxious family, the medical transport back to WA was cancelled. 'We couldn't understand why. Dad needs to be admitted to a neuro rehab facility once a bed becomes available back home,' Ms Moloney said. 'Dad's speech has been impacted quite severely, he is quite hard to understand now. He also has issues with his right arm, and his high-level balance. Flying home commercially is not an option for us, with his condition.' Ms Moloney was told that neither the WA or NT governments wanted to pay for dad to get home, even though he needed to be admitted to a neuro-rehab facility. 'The Royal Flying Doctor Service quoted $80,000 to fly Dad home. Mum and Dad have premium Ambulance cover which covers Air Ambulance but the health fund advised mum that St Johns Ambulance in Darwin do the patient transfers. 'When called, St Johns gave mum a flat no, with no reason why. 'Mum had another quote that will provide a nurse on a commercial flight to sit in business class with dad and that costs $15,000. 'Where is she supposed to get all this money from when she has already spent thousands on accommodation so far to stay with dad? 'It's been a nightmare. We just want to get him home safely and get the ongoing care he needs. 'My dad is the most beautiful man. When he was of sound mind he would go out of his way to help anyone. Well now he needs help and we just can't get it.'

Professor Richard Scolyer completes 250th Parkrun, a goal set after cancer diagnosis
Former Australian of the Year Richard Scolyer has completed his 250th Parkrun — a milestone he set after he was diagnosed with terminal brain cancer in 2023. The renowned melanoma researcher was among hundreds of runners who took part in the Greenway Parkrun at Haberfield in Sydney's inner west on Saturday morning. Professor Scolyer, who put himself forward as "patient zero" for revolutionary brain cancer treatment, crossed the finish line to applause and cheers from the crowd. Shortly after he finished the race, light rain began to fall and a rainbow formed over the reserve. When speaking to the media, he said 250 Parkruns was a "big goal" he set for himself. "I did a lot of Parkruns in the early 2000s but then as the kids go through various parts of their life you stop doing it," he said. "And then when I got sick again I wanted to try and get to 250. "I guess it's part of my personality. Bit embarrassing, but wanting to get to 250 was something that pushed me along." Professor Scolyer said it was "crazy" to see such a huge turnout at the run and that he was "very happy" to complete his goal. Professor Scolyer said he had doubts about whether he would reach the major milestone. "To be honest, I never thought I'd get there," he said. In a post to his more than 20,000 followers on X earlier this week, he wrote that it was a goal "I wasn't sure I'd reach" and that he was excited to be able to take part in the run. "So it's with a huge amount of gratitude to my family, friends, and medical team that I'll be celebrating this achievement," he said. The post on social media came after a long period of no updates, which Professor Scolyer said was due to the impact of his latest round of cancer treatment, but that he now felt "like the fog has lifted a bit". Professor Scolyer was diagnosed with an aggressive glioblastoma in 2023 and was given just six to eight months to live. But an experimental immunotherapy treatment he was given managed to keep the cancer at bay for almost two years with no recurrence. However, he revealed in March that after undergoing scans, he had received the heartbreaking news that his brain cancer had come back. In May, he had another setback, revealing that his first proper scan since the surgery showed the glioblastoma had progressed and it was getting "harder to treat". He told ABC News Breakfast last month he wasn't sure how much time he had left. "I'm still here and still able to chat to you so I'm pretty pleased about that," he said. "Who knows how long I've got. Could be months, could be less." Professor Scolyer said he's focused on spending the time he has left doing the things he loves most. "I love my life. I love the interactions I have with so many people. "I guess in reality, I have focused down on the things that I like doing. Spending more time with my family is number one, but also contributing to society. It's something I've done for a long, long time. "I've been a specialist for more than 25 years now. So a lot of things that I've done I don't want to give up just like that." Professor Scolyer has been very public and honest about his prognosis and journey through brain cancer treatment in interviews, social media and in his recent memoir, Brainstorm. His memoir, which was co-written with Garry Maddox, won the Social Impact Book of the Year at the Australian Book Industry Awards in Melbourne last month.

‘Powerful jaws': Postie reveals horrific trauma after vicious dog attack on the job
A Perth postie has revealed the horrific trauma she suffered after a brutal dog attack while on the job. It comes as Australia Post announced plans to arm posties with citronella spray to fend of dangerous dogs, and a new study revealed nine posties are attacked on average every day across the country. Bronwyn Adamson had been working for Australia Post as a postie on an electric delivery vehicle (EDV) for only a few short weeks in Perth when she was targeted by a dog while doing her postal run. The attack left her with lifelong scars and trauma. She has 17 years of experience as a veterinarian nurse under her belt and has adopted several rescue dogs with '(traumatic) pasts', giving her plenty of experience with unpredictable animals. However, an hour-and-a-half into her postal run, she arrived at a house for a parcel delivery that required a signature, 'walked up and knocked on the door'. A male voice boomed from the side gate, telling Ms Adamson he'd be right there to sign for the package. 'I turned to (face) that voice, and next thing, this dog just launched at me and bit my breast,' she said, a feeling she described as 'very unpleasant'. 'I don't know what breed (it was), but it had powerful jaws,' she recalled. 'It (made) a puncture wound on my left breast and left extensive bruising.' The man was 'very apologetic' after the incident, and 'growled' at the dog to scare it away, but the damage was done. In the weeks that passed, the bruising became so extensive that it 'ended up in a haematoma about the size of a golf ball'. Ms Adamson's recovery has taken months, and she has only recently been given the all clear by her doctors. 'It was a very painful experience,' she said. On average, there are nine reported attacks on posties every day across the country, though attacks are more common in certain states and suburbs. Western Australia, where Ms Adamson works, is the third worst-affected state in the country for dog attacks on posties, with 184 reported attacks in areas including Joondalup, Geraldton and Malaga between November 15, 2024 and May 15, 2025. Leading the pack is Queensland, which has reported 388 incidents in the last six months, with the worst-affected areas Darra, Bundamba and Toowoomba. In NSW, the second-most affected state in the country, Australia Post reported 329 incidents, with the worst three areas Moree, Penrith and Waterloo. Victoria is fourth worst, reporting 138 incidents, with the majority of dog attacks happening in Oakleigh South, Mooroolbark, Deepdene and Mornington. 'Moree in NSW is one of many hotspots where the number of roaming and unrestrained dogs has created dangerous conditions for our posties,' Australia Post general manager safety Russell Munro said in a statement. 'When our people continue to end up in hospital, we have a responsibility to act and this (using citronella spray) is a last-resort measure.' The most common incidents occur when dogs are roaming around or escaping from a person's property, with 57 per cent of all attacks happening while the dog is on the street. However, nearly 40 per cent of all cases happen on the customer's property – half of which occur when they open their front door. Ms Adamson said she wasn't the only one in her area to suffer at the hands of unruly dogs. '(Attacks) have happened to quite a few people here at the actual post office, and they've ended up in hospital because of puncture wounds, with lots of blood on knees and elbows,' she told NewsWire. 'It is a constant thing.' She said reactive dogs weren't necessarily a concern because owners generally knew how to keep them at bay. However, it's the 'friendliest, loveliest little dogs' that pose the biggest risk for posties. 'Unfortunately, (little dogs) see us as a threat because we come every day and we leave every day because they bark at us,' she said. 'And we keep coming back and they get angrier with us, until eventually, if they get out the door or if the gate gets left open, they'll bolt outside and bite us because that's their next line of defence.' It's a heartbreaking situation, she told NewsWire. 'I love dogs,' Ms Adamson said. While she has experience with reactive dogs and loves canines in general, Ms Anderson confessed the attack left her so traumatised it affected her job. 'I'm very conscious when I hear a dog barking,' she said. While most pet owners are 'very understanding' when she asks them to place their dogs behind a fly screen or in another room when delivering parcels, she's still 'terrified' when a dog's reaction is so strong it can 'rattle the glass windows'. 'I was terrified that the flimsy flyscreen was not going to work,' she told NewsWire. 'So I ended up carding the parcel and not approaching the door at all, so they had to go to the post office to pick it up.' Australia Post is taking the next steps to prevent further attacks on posties by introducing a water-based citronella spray to fend off attacking dogs. From the end of July, posties will be equipped with the spray, which is non-harmful and 80 per cent effective in making dogs retreat, but they should only use it as a last resort. Posties will also undergo extensive training to use the deterrent, which can only be used under strict protocols. 'The citronella spray will give me peace of mind,' Ms Adamson said. 'I'll feel safer knowing I have something that could protect me from another attack.'
