Phage therapy

Posted by kathyhg @kathyhg, Jan 12 7:34am

I just saw a commercial about a woman who had phage therapy for mycobacterium abscesses at the Mayo Clinic, with really good results. I’ve read a bit about phage therapy here, I think, but never paid much attention to it until now.

Has anyone had experience with phage therapy and/or know more about it? Is it a legitimate alternative to the medications, airway clearance, etc to treating NTM (I have Mac)?

Thanks in advance

Interested in more discussions like this? Go to the MAC & Bronchiectasis Support Group.

Belgium provides an online option for me on April 17, and then decide whether I need to go there in person. I prepared a list of questions during this online consultation. For example, did ther ever treat Mac - NTM patients before? What is risk aoosiciated with it? Will they treat patients who did not receive antibiotics.
If anyone is interested in phage therapy, I can provide an update after it. If you have any questions for the doctor, please feel free to share it. If there is a chance , I can ask during this online consultation.

Best,

Good luck, Helen. I hope it goes well on Wednesday.

Questions for Belgium - thanks for all the inputs!!
1) MAC is a group of bacteria, are you able to identify how many bacteria in my MAC? How does phage work ? Do you develop multiple virus to attack different strains of bacteria. Or you just use one virus to attack this group of bacteria? How long does it take to develop one virus, what is the cost?

2) If the immune systems were stimulated, will it make phage ineffective? I've seen cases that phage became ineffective after 6 months and the patient died. If there any side effects for phage therapy?

3) Have you ever treated any other patient with NTM-MAC and how effective is phage therapy?

Thanks for all the good postings!!!

Please let us know whether the Phage therapy was a clinical trail and if any doctor in particular was mentioned in the commercial.

Last week at the NYU Langone bronchiectasis and NTM patient conference, Dr. Doreen Addrizzo Harris mentioned that this year they will be participating in a trial for phage therapy and pseudomonas.
When I have more details, I will be sure to share them.

That would be great Linda, look forward to more details.

I have been following phage studies and I am not clear if this would work for pseudomonas that are antibacterial resistant and if it therefore eradicates the pseudomonas.

A huge step forward for people with CF and non-CF Bronchiectasis with mucoid pseudomonas!

Customized Phages can be developed if your pseudo is resistant to the standard Phages. Even with Phages the Pseudomonas is usually knocked back significantly but not eradicated. But side effects are not supposed to be an issue. Also using Phages and antibiotics together is not a conflict and can be very effective.

This is a really helpful discussion of phage therapy for those of us who are new to this idea. It’s exciting to think that, between drug trials and phage therapy, there will be more options for those of us who have NTM (Mac in my case).

Does anyone have any idea when it will be available in the US and/or Canada (which will likely be some time after the US)?

I found this by googling: Mayo Clinic's Phage Therapy Program, also known as bacteriophage therapy
, uses viruses to target and kill certain types of bacteria. The program was launched in 2019 by the Center for Individualized Medicine
. Gina Suh, M.D., is the director of the program.

There is currently a phage trial for people with bronchiectasis and pseudomonas called the Tailwind study:
https://clinicaltrials.gov/study/NCT05616221?cond=Pseudomonas%20Aeruginosa&term=Bacteriophages&rank=3

I wouldn't be eligible for this study as I have bronchiectasis and mac. I’ve contacted researchers for a number of studies that I’ve seen here and on bronchiectasis NTM facebook groups and they all seem to be limited to US residents and I am from Canada. I would be interested in trials/studies that are available to residents of Canada as well.
Thanks for keeping us up to date on what’s happening with bronchiectasis and NTM research.

Good morning,

Just talked to Dr. Dupont from UZ Leuven. He is such a respectable person! Very decent, very honest and respect his patients. He spent 30 mins thoroughly discussed phage therapy, answered all my questions and possible treatment methods. He is a real doctor.

The whole process is 1) provide the medical information to the hospital, 2) Give the sputum culture to laboratory and they test whether there is phage to your bacteria, if yes, 3) Return to Belgium to receive the treatment for 6 weeks. Every week, there is new medication ( phage). It is hard to ship the phage so it is better to receive the treatment in person.

As I am an international patient, there may be an option to send the sputum culture from USA to Belgium instead of going there in person. I will discuss with my doctor to see whether he can do this for me.

Phage is still in experimental stage and they have only two MAC patients and no successful cases yet. And these two patients are both using phage as a salvage. That means, they have tried all other therapies and none of them work. But a good thing is that phage therapy has no side effects from all of his patients (including patients of other illnesses).

So I am hesitating whether I should move forward. Anyone interested in seeking therapy in Belgium based on above? The total cost should be around $2000- $4000. It is kind of appealing to me as I really hesitate to go thorough antibiotics.
