Clinical Trials

About clinical trials

A clinical trial is a test in humans of an experimental medication or therapy. Clinical trials are experiments, not treatments, and participation requires careful consideration.

Although it's possible to benefit from participating in a clinical trial, it's also possible that no benefit — or even harm — may occur. Keep your MDA clinic doctor informed about any clinical trial participation. (Note that MDA has no ability to influence who is chosen to participate in a clinical trial.)

Research

Today, the focus of MDA-supported research in Lambert-Eaton myasthenic syndrome, as it is for other autoimmune (self-immune) diseases, is largely on regulating the immune response.

Several research groups are working on rebalancing the errant immune system, so that it returns to a state where it is able to attack invading microbes but not the body's own tissues. One especially promising avenue in this regard is increasing the activity or numbers of so-called regulatory T cells, which can dampen an overactive, or misdirected, immune response.

Medical Management

Long-term treatment and prognosis of LEMS depend on whether it occurs with or without cancer. Although cancer is life-threatening, it can be treated with radiation, surgery or chemotherapy. When these treatments are successful and the cancer goes into remission, LEMS usually goes into complete or partial remission as well.

Causes/Inheritance

Normally (A), the immune system releases antibodies to attack foreign invaders, such as bacteria. In autoimmune diseases (B), the antibodies mistakenly attack a person’s own tissues. In LEMS, they attack and damage muscle cells.

Diagnosis

In about 60 percent of cases, LEMS is associated with small-cell lung cancer (and more rarely with other types of cancer), which might be diagnosed at the same time as LEMS or years later.
