Guest guest Posted August 8, 2006 Report Share Posted August 8, 2006 A neurgolist here in the Twin Cities said he would be willing to prescribe CARNI-VALfor me. They've asked for a blood-test to see how many back-up copies of SMN2 I have. If enough (I don't know what the number is) they'll put me on the drug. Any pointers from those that have tried this approach? Quote Link to comment Share on other sites More sharing options...
Guest guest Posted August 10, 2006 Report Share Posted August 10, 2006 I never heared about it. Can you give me a link / information about it?

Guest guest Posted August 10, 2006 Report Share Posted August 10, 2006 Bri-guy: I don't see what your SMN2 gene copy-count has to do with whether or not a doctor prescribes you VPA. Based on all sorts of studies on VPA & SMA - VPA acts on any number of SMN2 genes and - they think - causes more exon 7 & 8 inclusion in the protein production (SMN2 produces primarilly the shortened SMN Delta 7 protein). The main concerns with VPA are/should be monitoring possible side effects first (because in the most extreme - can kill you) - regular blood tests - every 4 to 6 months should accompany anyone taking VPA - off-lable or not. Supposed " Able Bodied " people have 2 copies of both SMN1 and SMN2 genes. Type 1 SMA is usually a result of 1 or 2 copies of the SMN2 gene. TYpe 2 SMA typically has from 2 to 4 copies of SMN2. Type 3 SMA usually have 3 or more copies of SMN2. I don't believe the current CarniVal trial has an SMN2 copy count criteria - thus, I see no reason for your neurologist to impose one on you. If you do go forward with it - I hope it helps you!

Guest guest Posted August 10, 2006 Report Share Posted August 10, 2006 Great info Mitch. I'll bring your post to my doctors appointment for good discussion point. I believe they are under the assumption that the results are better with a higher SMN2 count. But what you say makes sense too. Thanks for the well wishes, I'll definitely do the routine blood- tests to make sure nothing nasty is happening. I don't hold out high hopes, but it worth a shot. > > > A neurgolist here in the Twin Cities said he would > > be willing to > > prescribe CARNI-VALfor me.

Guest guest Posted August 10, 2006 Report Share Posted August 10, 2006 Bri-guy: It is correct to assume the more copies of the SMN2 gene, the larger the possible response of VPA usage would bring. Larger does not mean " more important. " Any increase - be it large or small - in flSMN protein MUST be a VERY GOOD thing for anyone with a disease/condition caused by a lack of it. If taking VPA or some other HDAC drug or even some other method of increasing the protein production - via RNA interference, gene therapy, etc. - doesn't matter how - or even how much necessarily in my oppinion - IF IT HELPS SOMEONE in some way - be it big or small (and who's to judge the level of importance) - than it is certainly worthwhile to at least be allowed to make the decision of whether to give it a shot or not. Yes the results are " better " if better only means more. " Better " for you is completely independent than " better " is to anyone else. If you have the courage to individually trial an FDA approved medication off-label, it should not be hindered by other's definition of the word " better. " If I was at that doctors office - I'd tell them to stick their SMN2 copy count criteria where the sun don't shine. Or " up their nose with a rubber hose " (a good Fonzie quote for you)...

Guest guest Posted August 10, 2006 Report Share Posted August 10, 2006 Mitch, I like your attitude. I sent a note to the geneticist at the clinic asking about the concern over SMN2 copy. She responded already stating that a small portion of individuals have no SMN2 copies at all. In these rare cases VPA would have no effect. So bottom line, if they are going to put me at risk of potential side-effects, then they want to be certain I have at least a chance of benefit from VPA. Makes sense. I never knew a SMN2 count could be 0. Especially for a Type II like me.

Guest guest Posted August 10, 2006 Report Share Posted August 10, 2006 I think they're wrong on that. The only people I know of with zero copies of both SMN1 & SMN2 genes are still-born or miscarried - at least based on what I've read or discussed with doctors, etc. Don't get me wrong, I'm not geneticist - I'm just a dumb guy dad with a business degree who's read a couple books, but that response you were sent below by the geneticist to me sounds pretty lame-brain to me. Thus, I see no reason for them to deny you your choice in this matter - because you certainly have more than 0 copies of SMN2 gene. --- <boojiboy@...> wrote: > Mitch, I like your attitude. > > I sent a note to the geneticist at the clinic asking > about the > concern over SMN2 copy.

Guest guest Posted August 11, 2006 Report Share Posted August 11, 2006 From what I understand the blood test is for a liver function test to see if your liver can handle the medication. I am using the drug now and not with the carnitine because the liver damage is rare and usually only happens to very young children 2 and under. I have to have my blood tested every few months to check my liver just to make sure no damage is being done. <boojiboy@...> wrote: Great info Mitch.

Guest guest Posted August 11, 2006 Report Share Posted August 11, 2006 Hi Joy: I hope your personal trial of the medication helps you! Regarding the carnitine - and why its part of the " Carni-Val " trial therapy - it isn't because of liver considerations, though you are correct in that liver complications with VPA are some of the biggest concerns. Carnitine -as naturally produced by one's own body, it seems, was being depleted due to VPA usage. Natural carnitine levels, I believe, in some of the children early on in the Phase 1 trial were apparently being depleted due to VPA usage - and in blood tests showed extreme low levels of carnitine. Low carnitine levels can cause increasing problems with the functioning of one's muscles (so I'm told) - thus potentially off-setting any gains due to VPA usage. I would make sure your neurologist carefully monitor your carnitine levels along with liver functions ( & all else they look at) via regular blood draws. Additionally - I think you should seriously consider adding a carnitine supplement to your diet or medication. Good luck - Mitch --- Joy <j0yeuxx@...> wrote: > From what I understand the blood test is for a liver > function test to see if your liver can handle the > medication.

Guest guest Posted August 11, 2006 Report Share Posted August 11, 2006 I'm also just a dumb guy who happens to read every piece of info on SMA that I can find, and everything I have read says that Mitch is right. Animal studies of SMA have shown that humans seem to be the only animal with any SMN2 genes at all. Animals only have SMN1, and if you take that away they die in the womb. Someone who has SMA (which by definition means no SMN1 gene) and also has no SMN2 copies would not be able to survive. If you have SMA Type 2, you must have some SMN protein, therefore you must have at least one copy of SMN2, therefore VPA might help. This article about VPA in Type 3 adults mentions the SMN2 issue. It might be true that the more SMN2 copies you have, the more VPA will increase the protein, but even a small increase may be beneficial for someone with very little to start with. http://tinyurl.com/zol7t Good luck! 2006/8/11, <mongomustgolf@...>: > I think they're wrong on that.

Guest guest Posted August 12, 2006 Report Share Posted August 12, 2006 Great article. Thanks. Yeah, it does makes sense that if I had no SMN2 I'd be dead. I'll let them get the results of the blood test and wait until my appointment to ask the doctor about it. > > I'm also just a dumb guy who happens to read every piece of info on > SMA that I can find, and everything I have read says that Mitch is > right.

Guest guest Posted August 14, 2006 Report Share Posted August 14, 2006 If an animal does not have SMN2 genes, how can we use SMA mouses or Zebra animal models to test a drug which might potentially up-regulate SMN2 genes to make more SMN protein? --- Senior <jsenior@...> wrote: > I'm also just a dumb guy who happens to read every > piece of info on > SMA that I can find, and everything I have read says > that Mitch is > right.

Guest guest Posted August 25, 2006 Report Share Posted August 25, 2006 I got my SMN2 gene copy test back. They called in inconclusive! My geneticist said that this probably means they weren't willing to make the call between 0 or 1 copy, 2 and 3 copies, etc. etc. I find this odd since they wanted to ensure I had at least one copy ensuring that VPA would at least have a chance at benefit. I had the discussion again stating that if I had 0 copies, I wouldn't be here asking about it. Once again, the geneticist emphasized that they do indeed get patients with 0 copies. She said that in these cases the SMN gene isn't actually deleted, but instead is defective, partially deleted or what she called, 'migrated'. They are going to go ahead with VPA with me and redo the test later. Thought folks would be interested in this little tidbit of info. > > > > > I'm also just a dumb guy who happens to read every > > > piece of info on > > > SMA that I can find, and everything I have read says > > > that Mitch is > > > right.

Guest guest Posted August 25, 2006 Report Share Posted August 25, 2006 Bri-guy: Interesting. That geneticist should talk with someone part of Project Cure (CariVal trial) or a member of AmSMArt or some knoweldgeable MDA doc - if you want to give them my name and email - I'll gladly direct them to some helpful doctor with more knowledge than I posses. SMN1 and SMN2 genes are identical with one very small exception in exon 7 of the SMN2 gene which causes the protein that is coded to not include various elements coded under exon 7 & 8 (SMN delta 7 protein). From what I've read, most seem to think the SMN2 gene originated as a mutated form of the SMN1 gene. I suppose if the SMN1 gene is mutated some other way than to cause it appear as an SMN2 gene - and it is still capable of producing some amount of flSMNprotein (which seems unlikely if the gene has been partly deleted or 'migrated') - along with having no SMN2 genes (note the SMN2 gene is still able to produce flSMN protein ~10% of the time despite the coding error), that someone could indeed have SMA - though I've not heard of this. Regardless, best wishes for you - I hope the trial proves beneficial for you! Mitch --- <boojiboy@...> wrote: > I got my SMN2 gene copy test back. They called in > inconclusive!

Guest guest Posted October 23, 2006 Report Share Posted October 23, 2006 Time to resurrect this thread with an update. I met with my neurologist today and he was very open to the VPA treatment. However, he ultimately talked me into delaying it for 4-6 months. It's his belief that there may be information soon to lead researchers to prescribe sodium phenylbutyrate instead of VPA. In addition, he believes there will be a coordinated trial for adults underway soon that I could participate in. This way, I get the medicine AND I'm being tracked according to the protocol of the trial. Finally, and I admit what I am about to say is technically over my head because I haven't looked into it yet. But, my neurologist talked about histone deacetylase (HDAC)inhibitors. This is what VPA and sodium phenylbutyrate are. He believe there was a new generation of these specific inhibitors in the works and that the understanding of those inhibitors and their impact on diseases like SMA is grown a lot in the past couple years. So, none of this is probably new for those of you that keep abreast of research. But, I'll set up another appointment for 6 months from now and see what's cooking. In the meantime, he prescribed Mestodone (sp?) for a little energy boost when I need it. He thought it worked for about half the folks who try it. > > > > > > > > > I'm also just a dumb guy who happens to read > > every > > > > > piece of info on > > > > > SMA that I can find, and everything I have > > read says > > > > > that Mitch is > > > > > right.

Guest guest Posted October 23, 2006 Report Share Posted October 23, 2006 , Could it be Mestinon? If yes, then that is what I take every day!!!!!!!! I fiddled around with the dosage until I found one that gave me the most boost with the least amount of side effect; for me it's 30mg or half a pill mornings. I take it while doing my " business on the bed pan " so I am relaxed while my med soaks into my system. I can do without it, but it lessens my frustrations when moving about.
