LTR Pharma & co-development partner Aptar Pharma complete extractables study on SPONTAN
All identified compounds below ICH safety thresholds for nasal spray-mist erectile dysfunction treatment
Leachables study initiated to support FDA regulatory submission under real-world storage conditions
Special Report: LTR Pharma has completed a key extractables study for its SPONTAN intranasal spray for erectile dysfunction and kicked off a leachables study as part of a regulatory development program.
LTR Pharma (ASX:LTP) said the extractables study, conducted under the supervision of co-development partner Aptar Pharma, evaluated the bottle and pump components of SPONTAN's container closure system.
The study confirmed that all detected compounds were below ICH safety thresholds – the internationally recognised standards adopted by the US Food and Drug Administration (FDA) and regulatory authorities worldwide for pharmaceutical impurities.
LTR Pharma said the identified compounds would be monitored in the ongoing leachables study.
FDA requires extractables and leachables (E&L) studies for all pharmaceutical products to ensure packaging materials do not compromise product safety or efficacy.
For nasal spray products, these studies must meet specific regulatory thresholds due to direct tissue exposure.
Leachables study now underway
The leachables study has started under Aptar Pharma's management, evaluating the potential migration of the compounds from packaging into SPONTAN under real-world storage conditions.
LTR Pharma said SPONTAN used industry-standard bottle and pump components as used in multiple FDA-approved nasal spray products.
The study will run for at least 24 months to support shelf-life requirements. Consistent with FDA practice for nasal sprays, the company can submit its application once sufficient robust data is available, with study completion continuing post-approval as standard.
E&L studies form part of LTR Pharma's comprehensive regulatory strategy following its FDA pre-IND meeting, where the FDA confirmed the proposed development pathway.
The company said E&L data were required for the chemistry, manufacturing and controls (CMC) section of its planned new drug application (NDA).
With extractables results meeting regulatory requirements, the company progresses to the leachables phase for comprehensive regulatory submission data.

Progress on SPONTAN and new US-targeted ROXUS
LTR Pharma continues to progress SPONTAN through established regulatory pathways while building commercial foundations through its Australian early access programs.
It is also progressing its new ED nasal spray called ROXUS, which offers a fast-track pathway to serve patients through the US personalised healthcare sector.
As with SPONTAN, ROXUS is based on the common active ingredient vardenafil. It will be delivered via the 503(a)-compounding pharmacy pathway, which exempts drugs from the usual approval, labelling and manufacturing requirements.
"The completion of our extractables study and commencement of the leachables phase keep our regulatory program on schedule,' LTR Pharma executive chairman Lee Rodne said.
'Working with Aptar Pharma provides us with their established expertise in nasal spray device development and FDA submissions.
'These studies are necessary steps in our development pathway, and we look forward to progressing through each regulatory milestone."

‘Dying in silence': Closing restaurant shares sad ‘wake-up call'

A beloved Sydney Italian restaurant – which was once booked out 'every weekend'- is set to close its doors, with its owner sharing a 'wake-up call' to Aussies as small businesses are left 'dying in silence'. Zafferano Trattoria Mediterranea, owned by Sicilian-born chef Simone Crivello and partner Isobel Galloway, has been serving up authentic Sicilian food in Paddington, in Sydney's inner-east, for over five years. But amid the cost of living crisis and climbing rents, the popular restaurant has made the difficult decision to close in August, highlighting the struggles the Sydney hospitality industry faces in a poignant video message on social media. 'Sydney, what happened to you? This used to be one of the most vibrant cities in the world,' Ms Galloway said in a video on the restaurant's Instagram page, which was not intended as a 'pity post' but rather a 'wake-up call'. 'Our restaurant was once full, bookings every night, laughter echoing through the walls, and food made with soul. Now, we're lucky if a few tables fill.' Ms Galloway acknowledged Zafferano is not the only restaurant struggling, claiming Australia is grappling with a recession. 'Small businesses are dying in silence while rent climbs, costs soar, and politicians pretend everything is fine.' 'We're in a recession, whether they wanna say it or not. People can't afford to go out. Families are struggling, somehow the government still acts like this is just a phase, but it's not. It's the reality they helped create,' she claimed. 'The economy is tanking, and the people who built this city – the chefs, the creatives, the small business owners – we're the ones paying the price.' Ms Galloway said her restaurant is having to shut not because it 'failed, but because the system did'. 'Before we go – ask yourself this. Where are you spending your money? Who are you choosing to support? And what kind of city do you want to live in?' she continued. 'Without small businesses, culture dies, community dies, and all that's left is soulless chains and boarded-up shop fronts. This isn't just a goodbye, it's a wake-up call,' she concluded. The restaurant further called on Sydneysiders to choose local and support Sydney it said has 'been left to crumble'. 'If we don't fight for what matters … there won't be anything left to fight for,' it captioned the post. Many Aussies praised Ms Galloway for highlighting the struggles many businesses continue to face. 'This makes me so sad,' one person wrote. '100% agree, we have been in a recession for about two years now,' another wrote. 'Finally someone being honest and transparent about what's really going on! Small business needs support and some tax breaks to help keep the culture alive!,' said another. Speaking to The Daily Telegraph, Ms Galloway said she and her husband, who welcomed a child in February, said they made the decision to not renew their lease after spending the last 18 months enduring the cost-of-living ciris as well as increased rent and wages. 'The past two years have been notoriously tough for hospitality,' she said. 'It's been a really tricky time and all venues have had to deal with it. But being tiny and family run, it's taken toll on us. Ms Galloway added they 'would have happily stayed in business for next 20 years but we can't afford to'. Looking to the future, the couple said they will be releasing a cookbook and plan to host food tours and open a B&B in Sicily. They will shut their doors at the end of August. NSW cafe braces for latest financial hit Zafferano isn't alone in feeling the crunch. Three Flamingos Espresso, a beloved cafe in Albion Park, near Wollongong, has been struggling with sharp increases to the cost of insurance, electricity, produce and stock – all of which has seen its profit margin shrink to a razor-thin five per cent. Owner Brad Pettitt told earlier this month he was bracing for the latest financial hit after the Fair Work Commission announced a 3.5 per cent hike to the minimum wage starting on July 1. 'Our staff work really hard and they absolutely should be rewarded, but in the context of all these other huge cost increases, it's really difficult to cope,' Mr Pettitt said. 'In the past two years, our electricity costs are up 40 per cent, gas 20 per cent, insurance and worker's comp both 10 per cent, coffee recently went up 15 per cent, bacon is up 10 per cent, and eggs, of course, the big one, is 44 per cent. 'The wage increase is modest for a few employees, but we have a staff of 24 so it all adds up to a big additional expense.' Millions of workers will see their hour rate lift to $24.95, a total of $948 per week based on 38 hours worked, up from $24.10 per hour and $915.90 per week. The Australian Industry Group estimated that the increase will see the national wages bill rise by $5 billion over the coming financial year. 'We're doing everything we can to diversify our income streams because we can't rely on day to day trade,' Mr Pettitt said. 'It's just not viable anymore.' He concedes an increase in menu prices is now inevitable. Industry groups say the larger-than-anticipated minimum wage increase will hurt vulnerable businesses, especially those in hospitality, and consumers will ultimately pay.

Master of the market comes in from the cold

The farrago around Pointsbet's $402 million sale to Japanese social media company Mixi has drawn its fair share of rubberneckers. Computershare botched tallying the shareholder vote last week, and missed rival Betr's attempts to block the deal. Betr wants to buy Pointsbet for itself. The brainchild of the bookmaker is the country's most famous bookmaker (and Melbourne Storm chairman) Matthew Tripp. And by swallowing up the ASX-listed Blue Bet last year, Betr became a public company.
