I had a two hour talk with Faraz from Bluebird. I have to say that the more I talk to him, the better feeling I get about Bluebird. It's not often that I hear the Golden Rule brought up in conversation, so I do take note that there is more to Bluebird than money, which is refreshing.
I received answers for most questions that were posed.
Chemotherapy concerns: Chemo brings the same risk of side effects that are present when used with BMT. Loss of fertility is a possibility, but is not predictable, so it is advised the sperm or eggs be collected in advance. Short term side effects from the chemo are a known factor. Reminder: There is no risk of graft vs host disease, removing the biggest concern about BMT. There is nothing to reject, as the patient's own bone marrow is collected and used.
Long term costs: We don't know yet. Patients must continue chelation afterwards until their iron burden is normal, but aside from that, nothing long term is currently known. In theory, there should be no long term issues, but one of the reasons trials are run is to observe over longer periods. As far as long term maintenance, no immunosuppression drugs or other drugs are required.
Are transfusions required after the process? Patients are transfused to a high Hb before the process begins. Only a couple have needed any blood at all after the procedure, and that involved transfusing only small amounts of blood one time. After that, they remain transfusion-free.
Will patients lives eventually become normal? That is the hope and nothing currently known suggests otherwise.
Have there been any setbacks or unforeseen issues? Not so far, and they learn more from each new patient.
Have things changed a lot since the first patient was treated 7 years ago in France? The process continues to become more refined and with each new patient, more is learned. The vector used today is improved and more effective, but there haven't been any major changes. The first patient continues transfusion-free, as have all subsequent patients.
Recruitment for trials: See
http://www.northstarstudy.com/resources.html and begin the screening process if interested. The current trials are almost full, but a few more patients will make it into these ongoing trials which are taking place in the US, France, Thailand and Australia. Current patient origins are from France, the US, Pakistan, Australia, Thailand and Syria. More trials will be coming and the age limit will be lifted, allowing younger and older patients to apply.
There has been no trouble attracting patients for trials, and with this recent report, we can expect interest to increase, so it is highly recommended that interested patients begin the screening process ASAP, so they can get in the queue and have a chance of being selected for trials. I have seen nothing in any report that should cause any hesitation applying for participation in trials. Bluebird takes care of the cost for the trials, including transportation costs, so do not be deterred by your location.
Re: Sickle Cell: The first patient has been started but it is too early for any reports. With sickle cell, stem cell mobilization has to be carefully done, as the drugs used can mobilize the production of more sickle cells, as well so achieving proper dosing and use of mobilization drugs will take some time and experience. We will eagerly await further reports. It's exciting that the trials have expanded beyond thalassemia.
I have never had any doubts about the eventual success of gene therapy. The waiting has been agonizing, but we are now well on the road to a new era of medicine. We are living in miraculous times and we need to seize the moment and not allow research to be deterred by political buffoons who constantly threaten to de-fund research, as we in the US saw last year with the government shutdown. As world citizens, we should demand better from our leaders. Let's demand that our tax dollars go to helping solve the real problems humanity faces, rather than fund more exploitation of humanity through conflict and wars. There are so many avenues of research taking place to find treatments and cures for a multitude of disorders and diseases, and in most cases, the only thing holding them back is lack of funding for research. We have seen this over the past 10 years regarding gene therapy. We are a couple years behind in the US, due to earlier lack of funding. At every conference, you can find researchers presenting their work, and so much shows real promise, but always the same stumbling block is present and that is lack of support for research. Let's make a conscience decision to support saving humanity, rather than destroying it.
I have attached the latest report as a pdf attachment to this post.
