🌍 Celebrating Rare Disease Day 🌍

Rare Disease Day happens every year on February 28 (or 29 in leap years)—the rarest day of all. For MDDA and the IEM community, Rare Disease Day is a chance to share our experiences, teach others about living with a rare disease, and talk to policy makers. It creates a feeling of togetherness and common goals as we go through life in the IEM community. Let’s stand together on Rare Disease Day, raising awareness, pushing for change, and supporting each other on our special journey. This day reminds us that even though globally each rare disease affects only a small number of people, together they impact over 300 million individuals worldwide. Rare Disease Day brings hope and strength to many of us. It shows that our challenges are recognised, and our efforts to speak up can make a real difference. This day sheds light on the unique obstacles we face, from limited treatment choices to the complexities of managing our health. By spreading awareness, Rare Disease Day helps us get more funding for research, find new solutions, and improve access to the right healthcare.
Rare Disease Day 2024 🤝 🌐💚 Share your story, spread the word. Let’s make Rare Disease Day a day that transforms lives! 🚀 #RareDiseaseDay #UnityInRare #MDDA

BREAKING NEWS - An important win for the Australian PKU Community!

The Metabolic Dietary Disorders Association (MDDA) is excited to share the long-awaited news that as of 1 April 2023, Kuvan (sapropterin dihydrochloride) is now available on the Pharmaceutical Benefits Scheme (PBS) for the treatment of sapropterin-responsive adults living with hyperphenylalaninemia (HPA) due to phenylketonuria (PKU)! This follows the positive recommendation from the Pharmaceutical Benefits Advisory Committee (PBAC) in July 2022, which found that “sapropterin provides, for some patients, a significant improvement in efficacy over a Phe-restricted diet alone” and acknowledging “there was a high clinical need in a small patient population.”

2023 Reminder - Important Information About the IEM Food Grant

The Department of Health and Aged Care (the Department) review of clients who receive a monthly benefit payment under the Inborn Errors of Metabolism (IEM) program has begun. If you have received a letter from the Department advising that you have an overdue reapplication you must act now. The IEM programme office are happy to take calls from anyone who had received a letter to explain to them what is required or you may direct any enquiries to MDDA.  It is a requirement of the IEM program that clients with dihydropteridine reductase, hyperphenylalaninemia or phenylketonuria are reassessed by their metabolic specialist and submit a reapplication form (Form A) every 12 months. Your monthly benefit payments may be suspended if the Department does not receive your reapplication form every year. The reapplication form (Form A) can be found on the Department’s website at https://www.health.gov.au/initiatives-and-programs/inborn-errors-of-metabolism-program. MDDA are planning an information webinar later in March with the Department for IEM grant recipients providing an opportunity to hear directly from the Department.

Today is Rare Disease Day!

Rare Disease Day takes place on the last day of February, the rarest day of the year! MDDA joins rare disease groups from across the world to celebrate International Rare Disease Day! This important international campaign aims to raise awareness amongst the public and decision makers about rare diseases and their impact on patients’ lives.
MDDA celebrates all of those who live with a rare disease. We are committed to improve understanding and awareness of all rare diseases and will continue to advocate for research and better treatment and support of all IEMs.

With the Summer holiday fun coming to a close, for many of our IEM families it means time to get ready for another school year! This can be a time of both anticipation and excitement, and if it is the first time your child will spend long periods of time out of your care, some concern. With pre-planning, children with PKU/IEMs can easily make this transition and keep their PKU/IEM well controlled. Over the years our supportive IEM community have shared invaluable tips, advice, and FAQ’s that the MDDA have pulled together to create an online “School Starter” resource which you can access here! https://mdda.org.au/school-starters/ ...

The Department of Health and Aged Care (the Department) will be undertaking a review of clients who receive a monthly benefit payment under the Inborn Errors of Metabolism (IEM) program. The review will focus on ensuring client contact details are current and that Program reapplication requirements are met. The Department has informed the MDDA that clients with overdue reapplications will be contacted early in 2023 in regard to their reapplication.
It is a requirement of the IEM program that clients with dihydropteridine reductase, hyperphenylalaninemia or phenylketonuria are reassessed by their metabolic specialist and submit a reapplication form (Form A) every 12 months.
If you are aware that you have an overdue reapplication you are encouraged to schedule an appointment with your metabolic specialist and submit your reapplication to the IEM Program Officer. Your monthly benefit payments may be suspended if the Department does not receive your reapplication form every year.
The reapplication form (Form A) can be found on the Department’s website at https://www.health.gov.au/initiatives-and-programs/inborn-errors-of-metabolism-program

We wish you a Merry Christmas and Happy New Year from everyone at the MDDA! 🎄

Team MDDA touched down yesterday and you won’t believe how beautiful this venue is! It’s the perfect venue for us to come together after 3 years apart to share, learn and catch up. We have over 75 families coming, both new and familiar faces. If you aren’t coming this weekend stay tuned to our social media to catch a glimpse of all the action. We can’t wait!


The Power of Advocacy a win for equitable treatment for the PKU Community.

Metabolic Dietary Disorders Association and PKUNSW Association are extremely pleased with the decision of the Pharmaceutical Benefits Advisory Committee (PBAC) to recommend the listing of Kuvan (sapropterin hydrochloride) on the Pharmaceutical Benefits Scheme (PBS) for all Australians living with phenylketonuria (PKU) who are responsive to this treatment. Whilst we are disappointed with the outcome that Palynziq was a rejection for listing on the PBS, we will continue to advocate on behalf of all eligible Australians with PKU for access to this treatment with the Australian Government.

Member Story: River Yuan, PKU.

It was 12th July 2019, when the Yuan family welcomed a beautiful baby boy into their world. Following newborn screening River was diagnosed with PKU. Soon after, his parents found a ‘new best friend’ for River – a rare disease medication that was recently added to the PBAC known as Sapropterin or Kuvan – which was listed after much advocacy and hard work by patient advocate and support group MDDA.

Kuvan is currently only available to children in Australia, leaving our rare adult population with nothing other than an ‘impossible lifelong diet’ to help protect them from the toxic amino acids found in protein that harm their brain. There is no cure for PKU!

Our “Make Some Noise for PKU” campaign is about advocating for access to this same treatment (and all available treatments) for adults with PKU.

MDDA thanks everyone who has supported our PBAC submission to get access to life changing drug therapies for PKU adults and now that consumer comments have closed, we will continue the dialogue with PBAC in the lead up to the decision expected in August. We are hopeful that Adults will be provided with the same opportunity that is extended to children just like little River, whose life was put on a different path thanks to him being given the opportunity to respond to a treatment to help manage his PKU.

We will continue to #makesomenoiseforpku so that ALL treatments can be available to ALL people with PKU.

For most people the start of winter means enjoying afternoon treats like this! Unfortunately not for those with PKU/IEM 🙁 A small hot chocolate and a scone with jam and cream is more than double the protein allowance of those on a low protein diet!
There is multiple ways to get involved in the Great Protein Challenge to help raise awareness for the individuals living with a protein IEM!
-Sign up to PLAY
-PLEDGE your support
-Contact your local MP to take on the Challenge
