March 4, 2010, end of Cycle 26:

Two years ago this week, I started on a trial of the new drug pomalidomide (then called CC-4047) with dexamethasone (DEX). Within a few months my M-spike was down from 2.7 to 1.0 g/dL, where it has remained since, going as low as 0.8 and as high as 1.1. Pomalidomide is good stuff. It seems to produce a response in most myelomiacs, including many for whom other treatments have failed to work. I do hope that Celgene and the FDA can get together quickly and get it approved.

I am currently taking only two prescribed drugs: (1) Pomalidomide, 2 mg per day; and (2) Aspirin, 325 mg per day. I would also take acyclovir to ward off shingles, but acyclovir is hard to get right now.

M-spike was unchanged at 1.0 g/dL at the end of this 28-day cycle. IgG was down 4% at 1130 mg/dL, which is probably good - IgI varies. Lambda free light chains (FLCs) are down a surprising 24%, yet Kappa FLCs are up, suggesting that the Lambda decrease is genuine. I'm not sure what the decrease in Lambda means, but it can't be bad. Total white cell count was 3.4 K/uL, down slightly to the lowest value I've ever had, just below the bottom of the reference range. But the white count bounces around, and neutrophils even went up a little, so we'll just watch it.

At worst, the tumor burden appears stable, despite discontinuing DEX three cycles ago, and at best it may have decreased just a little. Furthermore, neutrophils have stopped their downward slide. I'm a happy camper.

Dr L also ordered a bone-density (DEXA) scan this time. The result for the lumbar spine, vertabrae L1-L4, is a decrease in absolute density of 2% compared with another scan 2 1/2 years ago at a different facility. I'd rather it was an increase, but there could be that much variation between machines, and I'll take it. Results for the femur are less clear to me, because the previous facility reported only one value for femur, and Mayo reported two, called "femur neck" and "total hip." If the "femur neck" value is comparable to the femur value from the previous report, then density actually went up by about 5%. This is possible, because Vitamins D3 and K2 are known to strengthen bones, and I take them very regularly. In any case I still have osteopenia, but not osteoporosis, and I hope to discuss this more with Dr L.

Differences this cycle:
  • Dr L ordered 3 days of Biaxin at the beginning of the cycle. More about that below.
  • My 30-year chronic headache has started to return, now that I'm off DEX, and I took a capsule of naproxen sodium whenever the headache reminded me, once every day or two. Two years ago, not long after the trial started, the decline in M-spike gradually leveled off in the same months that I gradually stopped using naproxen. Was there a cause and effect? Since Celebrex (celecoxib), a similar NSAID, is thought to have a modest anti-myeloma benefit, it is possible that naproxen might also. In my amateurish and hopeful opinion, it is even possible that pomalidomide and naproxen might be synergistic. If so, we'll take advantage of it.
  • I started taking a new supplement, sodium copper chlorophyllin, one week before the blood draw. A recent article in Life Extension Magazine suggests that chlorophyllin may support neutrophil counts during chemotherapy. My neutrophil count did stop falling this time, actually going up slightly from 1.22 to 1.29 K/uL. Neutrophils bounce around a lot however, in response to bacterial threats in the body, so this is not very significant.
  • We ran another marathon eleven days ago. I've never noticed that a marathon affects the myeloma results, though.
Discussions with Dr L:
  • Biaxin (clarithromycin) is known to potentiate the combination of DEX and an IMID drug, such as Revlimid or thalidomide, and probably pomalidomide. Biaxin is no help by itself, and no one knows whether it would work with ONLY the IMID drug, without the DEX. Dr L prescribed a three-day course of Biaxin a month ago, to prevent a minor skin injury from becoming a major infection. Could those three days of Biaxin have helped the pomalidomide work on my tumor burden, even though I'm not taking DEX, and even though only three days?
  • She looked at the skin injury, now just a red spot, and thought it was healing rather slowly. In contrast, I thought it was healing fairly quickly compared with similar, prior experiences on DEX.
  • I asked if neutrophils are important to warding off shingles, since my neutrophils are slightly below the bottom of the reference range. She said no, that neutrophils attack bacterial infections, and lymphocytes are more important for shingles and other viruses. Happily, my lymphocytes are smack in the middle of the reference range.
  • Somehow the subject of Velcade came up, and she expressed the opinion that Velcade might not be in my short-term future, even if pomalidomide begins to fail, because the twice-weekly infusions and the attendant neuropathy would mess up my very-active lifestyle. I didn't mention that I would prefer once-weekly infusions, and by the way whose lifestyle is NOT messed up by Velcade infusions? I was happy with her patient-centered concern though. Anyway the discussion of the NEXT treatment after pomalidomide seems farther off now that it did a cycle ago.
  • I don't recall how this came up, but at one point Dr L said that in a given instance there may be a choice between any of several treatments, all of them good, none of them wrong. Anyway that's what I thought I heard - there may not be a BEST choice.
  • I had a bone-density (DEXA) scan this time. When the results of the scan were unknown, I mentioned to Dr L that if a bisphosphonate is indicated, I have a very strong preference for oral rather than IV. To my surprise she agreed wholeheartedly, saying that new information is coming out indicating that myeloma doctors may be over-treating with the IV meds (Aredia and Zometa). The half-life of those bisphosphonates in the bones is 10 years (or did she say 20 years). Too much bisphosphonate may stop the bones from losing density, but the bones may not regenerate themselves. Instead they become brittle and subject to fracture, especially the femur near the hip. Mayo will be coming out with a modification of their mSMART protocols, which may include oral bisphosphonates. At least three different oral bisphosphonates are available, and she wasn't yet sure which she might prefer for me. I think I'd also consult with my primary care physician, my other Dr L, who has a lot of experience with oral bisphosphonates.
What's Next:

I've been taking curcumin 8 g/day, sixteen capsules, and I'm tired of doing that. I might even say I hate it. Curcumin could be helping, but I have little evidence, so I'll stop it and see what happens. Quercetin too. I'll go back to one 500 mg capsule of curcumin per day, and no quercetin, reducing my daily consumption by 23 capsules. Yay!

The chlorophyllin supplement is new, and I will continue that, to support the neutrophils and because it is a good anti-mutagenic agent. I will also take one naproxen capsule per day. I use the liquid type, in the hope that it will be less likely to burn a hole in my innards as some NSAIDs can do.
