Treatment Name: Lenalidomide (Revlimid®)
How does Lenalidomide work?
Lenalidomide is designed to help the bone marrow produce more healthy and normal functioning cells. It is particularly effective in patients with MDS who are missing a piece of one of their chromosomes. This is known as “deletion 5q”.
Goals of therapy:
Lenalidomide is taken to help increase blood cell counts, reduce the amount of blood transfusions needed, and to prevent MDS from transforming to acute leukemia. Lenalidomide is not commonly given with the goal of curing MDS.
- Usual starting dose: Lenalidomide 10 mg oral capsule by mouth once daily for 21 days in a 28-day Cycle
Lenalidomide is dispensed by a specialty pharmacy in the R.E.M.S. Program and taken at home. Some patients may have doses for all 28 days or others may have seven days off to allow for blood cell counts to build back up (recover). This drug is taken until it no longer works or unacceptable side effects occur.
In clinical studies, the most commonly reported side effects with lenalidomide are shown here. Side effects sometimes have percentage ranges [example 55 – 75%] because they differed between in clinical studies:
How often is monitoring needed?
Labs (blood tests) may be checked before treatment, weekly during the first 8 weeks of treatment, then every 2 weeks for 8 weeks, then every 4 weeks thereafter. Bone marrow biopsy (sample) before starting treatment, after 12 weeks, after 24 weeks, then every 24 weeks thereafter and when disease progresses (gets worse). Labs often include: Complete Blood Count (CBC), Comprehensive Metabolic Panel (CMP), plus any others your doctor may order.
How often is imaging needed?
Imaging may be checked if there is concern for an infection or internal bleeding. Imaging may include: computerized tomography (CT) scans, Doppler ultrasound, and x-rays.
How might blood test results/imaging affect treatment?
Depending upon the results, your doctor may advise to decrease your dose, continue lenalidomide as planned, delay, or switch therapy.
- Report any unusual reactions to this medication to your cancer doctor, especially since this medication is taken at home
- If a female patient becomes pregnant or a male partner taking this drug impregnates a female, report to your cancer doctor immediately
- A pharmacist should ALWAYS review your medication list to ensure that drug interactions are prevented or managed appropriately
- Clinical trials may exist for MDS. Ask your doctor if any studies are currently enrolling in your area or go to clinicaltrials.gov and search “myelodysplastic syndrome” or "MDS" to find other centers offering study medications

What is Emotional Wellness?
Emotional wellness is having a positive outlook balanced with a realistic understanding of current life events. This requires both an awareness and acceptance of your emotions. It is with this knowledge that you can develop a plan to take the necessary actions to positively impact your life.
Emotional wellness uses an ongoing process to continually reflect on the stressors of life in a constructive manner to move forward and create happiness.
Because emotional wellness is deeply connected with physical, social, and spiritual wellness, pursuing it often becomes particularly difficult in times of major illness. Despite this difficulty, working toward emotional wellness has been connected to improved treatment outcomes and a higher likelihood of achieving goals of therapy.

What is Myelodysplastic Syndromes (MDS)?
Myelodysplastic Syndromes (MDS) are a group of blood disorders where the bone marrow either fails to make mature blood cells, or immature cells build up and crowd out normal cells preventing them from developing normally.
This often results in the bone marrow producing too few blood cells leading to: 1) A low white blood cell count (neutropenia), which can increase the risk of infection; 2) A low red blood cell count (anemia), which may contribute to weakness, fatigue, or shortness of breath; or 3) A low platelet count (thrombocytopenia), which can increase the risk of bleeding. Depending upon the type of MDS, some patients have neutropenia, AND anemia, AND thrombocytopenia.
In newly diagnosed cases of MDS, the causes are not always known. This is sometimes referred to as “de novo” MDS. However, exposure to certain chemicals, radiation, and chemotherapy are known to increase the risk of MDS. When causes are known, this is referred to as "secondary MDS." There are various subtypes of MDS and treatment depends on the specific subtype and risk level. High risk patients may be treated more aggressively than low risk patients. The effectiveness of treatment often depends upon the type of MDS as not all types respond the same way to treatment.

The R.E.M.S. program, which is Risk Evaluation and Mitigation Strategy, is an FDA (Food and Drug Administration) program that manages drugs known to cause potential serious risks. To make sure the benefits of these special drugs outweigh the risks, the FDA only allows designated pharmacies and doctors to dispense and prescribe these medications. There are many rules and regulations guiding the use of these drugs. This weblink to the FDA website will tell you more: http://www.accessdata.fda.gov/scripts/cder/rems/index.cfm
What is a CBC?
A Complete Blood Count (CBC) is a frequently ordered blood test that tells clinicians the status of your: 1) White blood cell count, 2) Hemoglobin, and 3) Platelet count at the time the test was taken.
1) White blood cell count (WBC): is used to determine infection risk, or response to chemotherapy. Certain chemotherapy agents may harm our good infection-fighting cells. Sometimes chemotherapy may need to be delayed to allow these cells to recover.
2) Hemoglobin: is used to determine if someone is anemic. Anytime the hemoglobin is below 12 g/dL, the person is said to be anemic. Red blood cell transfusions, and sometimes iron can be given to restore the hemoglobin level, but anemia treatment should always aim at treating the underlying cause or condition.
3) Platelet count: is used to determine if the risk of bleeding is increased or if a platelet transfusion is required to prevent bleeding. Certain medications that increase bleeding risk, such as: aspirin, certain chemotherapy agents, and blood thinners, may need to be stopped temporarily until the platelet count is within a safe range.
What is a CMP?
A Comprehensive Metabolic Panel (CMP) is a frequently ordered blood test that tells clinicians the status of your: 1) Electrolytes & Acid/Base status, 2) Kidney function, 3) Liver function, 4) Blood sugar, and 5) Calcium at the time the test was taken. It is commonly used to monitor liver and kidney function when beginning new medications such as chemotherapy. A total of 14 tests are run simultaneously and are shown below.
Electrolytes & Acid/Base status:
1) Sodium, 2) Potassium, 3) Carbon dioxide, 4) Chloride
5) BUN (blood urea nitrogen), 6) Serum creatinine (Scr)
7) AST, 8) ALT, 9) Total bilirubin, 10) Alk Phos, 11) Albumin, 12) Total protein
13) Serum glucose
14) Serum calcium
