Anyone take new drug Camzyos (mavacamten) for HCM?
Since FDA approval in April has anyone (non-clinical trial patient) actually obtained a prescription and had it filled? If so, when and where was the cardiologist located? Is the registration process for doctor/patient/Rx taking a long time for this much anticipated drug?
Thanks from a fellow patient!

Good comment, Deanna. When I was diagnosed with HCM, neither I nor anyone I knew ever heard of it. I think HCOM as a diagnosis is fairly new, as a condition it probably has been around for generations. I, too, was the heartbeat demonstration - glad I could help out. More is learned every day and in some places, young athletes are screened.
Hi Karen,
I am on month 2 of Camzyos. I went from 257 LVOT down to 57. Still on 3 blood pressure meds and still tired with naps. Hopefully this will improves. Did it improve for you right away or over time? Thanks.
Hi. I’ve been on Camzyos for almost a year. So glad to hear from Karen317. I felt better soon after starting Camzyos - more energy, less angina, fewer naps. But the LVOT gradient didn’t come down. My dr wanted me to stop Camzyos and have surgery. I persisted and asked to try higher dose instead. After 6 months the LVOT started to come down. I started on highest dose in November and by January the LVOT dropped from 119 to 58. By April this year it’s down to 7. I think some of us take longer to respond. If you’re feeling ok, stay with it! Great to hear about other people’s response. Thanks to all of you.
@nanakpm thank you for your advice for I was planning to do the same thing if I reach the same situation you have just increase the dosage and NO open heart surgery. My symptoms improved a lot but I do not know about my gradient till my first echo is done this coming 20th of April.
I do not mind even for maintenance be on camzyos for the rest of my life for it is worth it. My insurance covers that medicine even though that is an insurance I bought by myself and I do not work anymore for I took early retirement.
great to hear.
what is your current dose?
I started at 5mg, increased to 10mg after a few months, and now on 15mg which is apparently the highest dose currently approved. I was told that if the gradient did not come down within 4 months, it wouldn't work. I asked to try the increased dose of 10mg and the gradient came down slightly. Much bigger drop in gradient on the 15 mg.
I did the pharmacogenetic test (through a private provider) which showed I am a rapid metabolizer of camzyos.
I was reading some information on HCM it stated Atrial Fib and HCM are connected. You may want to look into it.

Thank you David for your comments. Yes I agree with you upon research but have had HOCM for around 15 yrs and pretty much symptom free (lately a few) but have never had Atrial fibrillation until I started Mavacamten (also a known side effect). I have had A F for around a month now and stopped Mavacamten about a month ago AF has stopped. Can only assume it’s the drug disappointingly. Very happy for those that have had their lives turned around. Regards
Thank god you got off the Mavacamten, I have not had too many side effects (knock on wood).
Have you had any side effects at all? My cardiologist said to me that anyone with an inherited heart condition (i.e. HOCM) will fare better on Mavacamten. I don’t have the inherited type so maybe that’s why. Keep well my friend.
