Just out: Double blind placebo controlled randomized trial of oral triplet Ixazomib-Rd vs Rd as frontline therapy of multiple myeloma. Helps elderly patients unable to travel.
Ixazomib is an oral proteasome inhibitor that is given once a week.
One pill once a week is a convenient way of delivering proteasome inhibitor therapy that otherwise takes a trip to the clinic.
CR and VGOR rates were higher with ixazomib-Rd vs placebo-Rd.
Median PFS: 35.3 months with ixazomib Rd vs 21.8 months with placebo-Rd, P = 0.073.
I think efficacy of ixazomib is less than bortezomib or carfilzomib. But in patients for whom travel once a week to clinic is difficult due to advanced age or frailty, ixazomib is a good alternative.
Especially during COVID times, and in high risk patients.
Ixazomib has previously shown significant clinical efficacy in relapsed myeloma and in maintenance therapy in double blind placebo controlled RCTs.
So the P value of 0.07 for PFS is not a concern for me. The drug works. We underestimated the sample size while designing the trial
Why do you often get confusing and contradictory messages from experts?
Why does medical expert opinion sometimes seem incorrect, outdated, or even contrary to the evidence?
1/ Medicine is really complicated. No one is truly an expert except in a tiny segment of it, at best.
2/ When a car doesn't work a good mechanic knows what each part does. To know what's wrong. Doesn't need a randomized trial to know how to fix it.
Our body is not like a car. We don't know a fraction of how it works and what each part does. Human biology is still in its infancy
3/ Medicine moves at speed of light. Keeping up to date is no small task. Even if you read all the latest information as they come in, you may have time to scan the headlines or abstract—
Not critically review it.
When we say "Vaccine Passport" some people may have negative reactions. I'd rather call it proof of vaccination.
The reality is that air travel and big gatherings in most places are likely to require proof of vaccination or a negative test. Of the two, I'd go with the vaccine.
Remember, your own friends and family may have small gatherings, and without being explicit they may only invite people who they know are vaccinated. Just for your own safety and theirs.
I strongly believe vaccines are they way to get us to normal, and soon.
As someone lucky to have been vaccinated, I can tell you the peace of mind is incredible.
Side effects: Milder in my experience than approved lymphoma CAR-Ts. Grade 3 or higher cytokine release syndrome (CRS) in 5% of patients. Grade 3 neurotoxic effects in 3%.
