Cytoxan instead of Revlimid

by dogmom on Tue Jan 12, 2016 6:27 pm

Well, our onc first mentioned Revlimid, but since my husband's acute kidney issue over the weekend, he has changed to dex and Cytoxan (cyclophosphamide). Both will be pill form.

I was just wondering if anyone knows if this will be it, or if a third agent might be added?

He is afraid the Revlimid will be too hard on his kidneys.

He was on high dose dex in the hospital, but what will the dose be for treatment? Also how often do you need labs, doctors' visits, etc, while on pill form chemo?

I assume on Cytoxan he will not be able to work and will need a leave.

Thanks

There are so many variables that go into deciding what dose of any medication to be prescribed. But, it is fairly common to start with 40 mg of dex once a week. The Cytoxan that your husband may be receiving won't limit him from working from what I've learned from reading experiences of others here. Revlimid can be hard on the kidneys so usually isn't prescribed when someone has recently had an acute kidney problem. He may also be prescribed one of the proteosome inhibitors such as Velcade (bortezomib), Kyrpolis (carfilzomib) or Ninlaro (ixazomib). The Velcade is usually a once a week injection, Kyprolis is usually a 2 times a week IV, and Ninlaro is the newly FDA approved pill.

I would bet that initially your husband will see the oncologist and have labs done at least once a week to follow his initial progress. There might be adjustments to his medications and doses as he responds to treatment.

When I was first diagnosed in Aug 2014, I was started on dex, lenalidomide (Revlimid) and bortezomib (Velcade). I relapsed after 4 months.

Then I took Revlimid, carfilzomib (Krypolis), and dex. After a few months, I started having chest pains and shortness of breath, and we discovered the carfilzomib was causing heart and lung damage, so that was stopped. The heart and lung damage has completely healed. Whew!

Now I'm on dex, pomalidomide (Pomalyst), and cyclophosphamide (Cytoxan). I've been on this combo for 6 months - I'm in my 7th cycle. So far, so good. I definitely think the side effects from this regimen are the best so far. I feel much better than I did on either Velcade/ Revlimid or Revlimid/ Krypolis. In fact, it was only with this regimen that I've even thought about trying to work part time. After the 8th cycle, I'll have complete re-staging (including PET CT, bone marrow biopsy and all the labs), and then we'll see if this combo is actually working.

Just my two cents.

I know Cytoxan has been around for a while in the treatment of multiple myeloma. Is it as reliable in putting it in remission as the newer drugs?

Hi dogmom,

For those with acute kidney issues, bortezomib, Cytoxan and dexamethasone (40 mg has been the usual dose during induction) is a tried and true induction formula. I'd be asking the oncologist why Velcade (bortezomib) is not included. With any luck, the kidney function will improve – possibly even reverse itself – during the first few months of induction therapy.

One of the things I learned at support group meetings is each case is truly unique. Clinical trial results are a starting point, but one must look at who was included/excluded from the trial. Multiple myeloma patients with ongoing kidney impairment historically have been excluded. That is starting to change, particularly for clinical trials for relapsed or refractory patients.

Have you gotten the genetic findings back from your husband's bone marrow biopsy? Has the oncologist identified the 'risk' group for your husband's case?

Wishing you all the best for good results from the treatment protocol.

Philatour,

No we learn the bone marrow biopsy results today. They were not back yet when he was dis­charged, as he was admitted the day it was done. I do hope the kidney issues will reverse themselves as he was very healthy prior to diagnosis. He may add the third drug today.

Thanks so much. I need all the help I can get.

They have added Velcade. So he is on CyborD.

Hi Dogmom,

CyBorD is the first line of treatment for multiple myeloma here in Canada (and Australia / New Zealand). From what I have heard from those who have had CyBorD, it has it's side effects, but generally no one reported being bedridden during this particular chemotherapy.
