Latest Multiple Myeloma Research Guide

This article is in progress as I put together resources on the latest multiple myeloma (MM) research for patients. This article represents advanced information about multiple myeloma for patients and care-givers that already understand the basics of multiple myeloma.

If you were just diagnosed with multiple myeloma, or otherwise are new to MM, then I would recommend you explore some of the basics of multiple myeloma resources here. If you are interested in induction, or the first chemotherapy you get after a new multiple myeloma diagnosis, you should probably check here.

This article is broader look at the 2020 ASH Conference and the subsequent research.

Multiple Myeloma Treatment Definitions Cheat Sheet

K = carfilzomib = Kyprolis

R = lenalidomide = Revlimid

KRd = dexamethasone = Kd

PFS = progression-free survival (you live, and your multiple myeloma does not get any worse, i.e. progress)

ASCT = autologous stem cell transplant (the typical stem cell transplant where you collect and reimplant your own stem cells)

DRd = daratumumab + Revlimid + dexamethasone

IRD = ixaxomib + Revlimid + dexamethasone

ERd = elotuzumab + Revlimid + dexamethasone

Isa = Isatuximab

Pom= pomalidomide (usually used in place of lenalidomide aka Revlimid)

bortezomib = Velcade

ORR = overall response rate

New Multiple Myeloma Research

This paper is a doozy, covering a lot of current multiple myeloma treatments. Published in March 2020. – Novel Experimental Drugs for Treatment of Multiple Myeloma

If you want to do your own search for real multiple myeloma research use the site operator on your Google searches. The way it works is that you search for your keyword and then add ‘site:gov’ at the end. This tells Google to only return results from websites that have a .gov domain.

You can go a step further and search ‘site:nih.gov’ but you’ll miss some things that way. Generally, just making it .gov filters out a lot of the noise.

Harnessing the Immune System Against Multiple Myeloma: Challenges and Opportunities

I guess this is the big one for me if I’m going on Elotuzumab:

Elotuzumab plus Pomalidomide and Dexamethasone for Multiple Myeloma – It’s from 2018, so that’s pretty recent.

Elotuzumab in combination with pomalidomide and dexamethasone for the treatment of multiple myeloma (2019 – says combination like elotuzumab-pomalidomide-dexamethasone will become standard 2nd line therapies. I guess I’m second line?)

Actors on the Scene: Immune Cells in the Myeloma Niche

Alternative strategies include the use of agents to disrupt BM-myeloma cell interactions. One of these agents is elotuzumab, a humanized mAb that binds to SLAMF7 (family member 7 of the signaling lymphocytic activation molecule), an immunomodulatory receptor expressed on several hematopoietic cells, including myeloma cells and NK cells (160162)

Multiple myeloma: the (r)evolution of current therapy and a glance into the future

Mechanisms of Action and Clinical Development of Elotuzumab (nih.gov) – This one made my head hurt, but it talks about how elotuzumab works.

Elotuzumab activates Natural Killer cells and the marks myeloma cells to be killed… but it’s complicated and involves SLAMF7, which is my new wrestling name.

According to this one, we got the order wrong… should be Elotuzumab before daratumumab. Since I was on dara for so short of time, maybe it doesn’t matter. Optimal sequence of daratumumab and elotuzumab in relapsed and refractory multiple myeloma

ASH Annual Meeting and Exposition and Multiple Myeloma

It is easy to forget that first and foremost, multiple myeloma is a blood disease. That means that in addition to being a cancer treated by oncologists, it is also right in the wheelhouse of hematologists.

The big hematology conference each year is the American Society of Hematology Annual Meeting and Exposition, or ASH Annual Meeting and Exposition.

This year, it’s the 62nd ASH Conference. Like most things this year, the conference was converted from a big meeting in San Diego, California to an all-virtual event to avoid issues from the Covid-19 pandemic.

Hematology and Multiple Myeloma

Obviously, not all of the presentations at a hematology conference have anything to do with multiple myeloma, but a lot a research does get presented at the conference. There are numerous Twitter users that do a good job of getting out summaries and notes about various presentations that might be of interest to the myeloma community, and, of course, to me.

One of the topics that keeps coming up is particularly disturbing to me.

An increasing amount of research shows that daratumumab is very effective against myeloma in almost every stage of treatment. Of particular concern to me is this concept.

Dara and Me

If you’ve been following along with me, you know that last year, I was put on a dara and 10mg revlimid cocktail for my maintenance regimen post-ASCT.

We stopped the revlimid almost right away. I took four infusions of dara. During that time, my immune system blood numbers went down, and down, and down, until they basically hit zero.

Shortly thereafter I ended up in the hospital where otherwise trivial bacterial and fungal infections forced me into the hospital for pretty much the whole month of June.

My oncologist suspects that I had a rare reaction (Oh goodie, here we go, a rare cancer, and a rare reaction) to Daratumumab in which it affect my immune system, and apparently made me lose my stem cell graph. We had to reinfuse stem cells that were left over from my ASCT to get my immune system back.

So… unless something has changed, dara and me do not go together. This looks increasingly like a bummer as much of the research presented this year at the ASH conference shows how great dara is at treating multiple myeloma, in pretty much all phases of the disease, and how adding it to other standard treatments improves outcomes in myeloma patients.

What Next Myeloma Treatment

If it sounds like there isn’t really a point, and that I’m mostly whining, you are not wrong. Fortunately, there were a lot of other presentations that I haven’t even got to looking at yet. There may be alternatives, and there are definitely new things coming down the pipeline.

It’s hard not to be encouraged by sentiments like this:

Now, more than ever:

Live to the Cure.

Cancer and CBD Oil

No matter what any CBD zealot tells you, CBD oil will not treat or help your actual cancer in any way. However, CBD can help many of the side-effects you get from from cancer.

I have multiple myeloma, a blood cancer. Like many of my fellow myeloma warriors, our cancer causes pain. CBD oil helps pain in some cases, but not all. It’s important to find out if CBD oil will really work for you.

Recommend CBD Oil for Neuropathy

One common reason to for cancer patients needing CBD oil is the pain caused by neuropathy. Neuropathy exists outside of the cancer population as well and has numerous causes. For cancer patients CBD is typically needed after chemotherapy causes neuropathy.

Neuropathy pain is tricky to treat. Some patients respond very well to some treatments, while others don’t respond to similar treatment. I take gabapentin three times a day. I know others who take higher or lower doses. Gabapentin is well tolerated in most people, so oncologists have no problem kicking up the dosage.

Sometimes though, even high doses of gabapentin don’t help. For me, the gabapentin helps quite a bit, but I still have significant pain in my feet. As you can imagine, this is limiting when it comes to being able to walk long distances or stand in line. This is a particular problem for my desired cancer comeback trip to Disneyworld and Universal Studio.

My physical therapist recommended CBD oil, but only after saying check with your doctor first. My oncologist said it was a good idea, and couldn’t hurt.

CBD Oil and Neuropathy

I live in Colorado where CBD oil, and marijuana itself are legal. It’s pretty easy to come by, maybe too easy. Both my PT and my doc warned me that CBD oil is not well regulated, and many oils are mostly just oil.

The solution is to buy CBD oil from a dispensary, instead of Amazon, or the back of the grocery store. The catch is that once I got to a marijuana dispensary, the very knowledgeable, and very honest, sales person informed me that to actually penetrate into the nerves and help with neuropathy, I would need higher concentrations than available as “recreational marijuana.” What I needed was “medical marijuana.”

I didn’t realize there was a difference other than licensing and taxes.

Effective CBD Oil and Neuropathy

The salesperson (excuse me, “budtender”) also recommended a tincture of at least 2,000. (I forgot the units). This got me wondering:

  • a) is CBD oil really effective for neuropathy?
  • b) if CBD oil is effective for neuropathy what dose is required?
  • c) is CBD oil not effective for neuropathy?
  • d) if CBD oil is not effective for neuropathy what is?

Like most people my first instinct was to Google. The top several results were dubious at best, composed of phony colleges, institutes, and organizations. Fortunately, the NIH was there to save the day.

The NIH, or National Institute of Health is a government organization that offers actual research studies on numerous topics, including legitimate CBD oil research and real CBD for neuropathy research included. Of course, this result is half way down the page, because the NIH does not spend big money and time on using SEO to rank highly for CBD topics.

Real CBD Oil for Neuropathy Research

One of the results I found was about the effectiveness of topical CBD oil on neuropathy of the lower extremities. In other words, does rubbing CBD oil on your feet help neuropathy pain?

There are two important things this true research about CBD oil for neuropathy in the feet tells us. The first is that yes, it does help neuropathy pain. Second, it tells us what dose they used. Most published research happens after the scientists involved already put some effort into the parameters. In other words, they already had and idea of what does would work for neuropathy of the feet. The does in the study was 250 mg CBD/3 fl. oz.

This means I’m looking for that dosage of CBD oil to be effective on foot neuropathy. Where do you find CBD oil for neuropathy and what does it cost? Most importantly, does CBD oil work for neuropathy from chemo?

I’m getting ready to find out. I’ll let you know.
