November 17, 2014 — Bye, Bye Bexxar

There are many ways our market-driven healthcare-funding system in the United States is just plain crazy, but one of the most damaging is the way it tends to suppress certain vital and effective medications. This has evidently just happened to Bexxar, which is no longer available. Along with its competitor Zevalin, Bexxar is a radioimmunotherapy agent.

Radioimmunotherapy is an ingenious bonding of a monoclonal antibody drug — Rituxan (rituximab) — with tiny radioactive particles. It delivers a one-two punch: the Rituxan chemically seeks out the cancer cells and the radioactive particle destroys them.

Radioimmunotherapy has proven to be very effective, and has the added advantage of doing its job in just one dose, with minimal side effects.

What’s not to like?

The people who really don’t like it are oncologists. And why? Because not many of them have the proper qualifications to administer it. As a hybrid of nuclear medicine and oncology, radioimmunotherapy requires doctors either to be dual-certified in both disciplines or to be part of a large clinic or group where both specialties are represented (a rare thing, in this case).

Many oncologists profit on two levels: both their professional fees and the fees they charge for running a chemotherapy suite. If their chemo suite doesn’t offer nuclear medicine as well, they lose a big chunk of change by referring a patient out.

An oncologist who refers a patient for radioimmunotherapy loses tens of thousands of dollars in billable fees. That’s a powerful financial incentive to stick with traditional chemo — even though that treatment takes longer (many months of infusions as compared to a single injection) and often has arduous side-effects.

This is not a problem for a large, multi-specialty clinic, but the typical oncology practice — which includes a group of oncologists only — can’t handle it. As Dr. Bruce Cheson of Georgetown University puts it, “patients had to be referred from one doctor to somebody somewhere else, which meant not only losing control of the patient, but also losing income from the patient.”

In many cases, radioimmunotherapy agents cost less — not as a single dose, but when averaged out over the total time required for treatment.

“There is actually no other drug out there with a track record like this,” writes Dr. Mark Kaminski of the University of Michigan, who helped devlop Bexxar. “Approximately 30% of patients can achieve long-term remission with Bexxar lasting over a decade. That's the biggest disappointment with this drug, now that it's gone, for patients with this disease — it was an easy treatment, it took only one week to finish, and if there were any side effects, they were all reversible. I've been giving Zevalin lately because I don't have Bexxar to work with, but I don't have as much confidence that it will be a solution for patients as much as Bexxar would have been.”

If we had a single-payer healthcare system (like Medicare), and if doctors practiced in multi-specialty clinics like the Mayo Clinic or the Cleveland Clinic — where they receive a salary rather than billing patients by the hour — then doctors wouldn’t stand to lose by recommending radioimmunotherapy. More patients would benefit.

Why do we expect physicians to be both medical practitioners and entrepreneurs? Sometimes those two functions are in conflict with one another, and this is a prime example.

Too often in our healthcare system, profits come first and patients second.

Carl, As always, spot on. It is tragic to lose a good treatment for all the wrong reasons. Much love, Betsy
