Brief summary: Trial Design:

This clinical trial is a phase III multicenter, randomized, double blind and controlled with placebo trial and with two arms designed to assess the efficiency and toxicity of the scheme Lenalidomide versus observation in a series of 60 patients with low risk myelodysplastic syndrome associated to 5q deletion with anemia (Hb≤12g/dL) but without the need of transfusion. Patients are randomized in the study in a 2:1 ratio. They will receive treatment for 104 weeks until progression of the disease, which implies that the patient suffering from anemia due to myelodysplastic syndrome requires transfusion of at least 2 UCH/56 days (2 months) with a minimum follow up of 112 days (4 months), or unacceptable toxicity.

Disease:

Low risk myelodysplastic syndrome associated to the loss of 5q without transfusion requirements.

Total number of patients:

In total 60 patients will be included, 40 assigned to the treatment branch and 20 to the placebo branch.

Calendar:

First patient first visit: February 2010, and Last patient last visit expected in February 2016. (Recruitment was initially expected to take place over a period of 24 months and was expected to be finished in February 2012, but due to low rate of recruitment it was extended until the population sample is included in the trial).

Detailed description: General summary of myelodysplastic syndrome with alteration in 5q. Myelodysplastic syndromes (MDS) are a very heterogenic group of diseases characterized by the presence of morphologic features of dyshemopoiesis in bone marrow (BM) and in peripheral blood (PB), which is translated into an inefficient hematopoiesis. This will lead to the concomitant development of peripheral cytopenias which will be the cause of complications in these patients and, in most cases, the cause of death. In addition, these patients have an increased risk of developing acute leukemia, and this risk increases with the progression of the disease.MDS represents an incurable disease with standard treatments with a quite variable survival mean ranging from 3 months to 15 years depending on the number of blasts, the number of cytopenias and the type of cytogenetic disorders2. The sole curative treatment of the MDS is the allogenic transplant of hematopoietic progenitors but this option is only available for a 5% of the patients with MDS.

Lenalidomide, initially known as CC-5013, is an analogue of the immunomodulator Drug Thalidomide (Thalidomid®; Pharmion Corp., Boulder, CO, USA), which was the first drug with anti-angiogenic and immunomodulator properties investigated in MDS. Lenalidomide has, as well as thalidomide, a broad array of potential activities against dysplastic cells, not fully known, among which we find immunomodulator and non-immunomodulator properties (anti-angiogenic effect, anti-proliferative and pro-apoptotic). The greater advantage of Lenalidomide in comparison with thalidomide is that the former is between 50 and 2000 times stronger tan thalidomide in what respects to its immunomodulator effects. And moreover, the toxic profile of Lenalidomide seems lower than that of its analogue; Thalidomide.

There is no treatment indication on the present times for patients with low risk MDS associated to the loss of 5q without transfusion dependent anemia. The results with Lenalidomide are highly promising for patients with low risk MDS associated to the loss of 5q when (it has so been tested) there is red blood cells transfusion dependent anemia. In this sense, the proposal consists on being able to state that treatment with Lenalidomide can be efficient from diagnose preventing CH transfusions with an acceptable toxicity.

In this sense, the present study has the intention to treat early patients with low-risk MDS associated to the loss of 5q with a view to prevent CH transfusion. Therefore, we could extend in these patients the time until CH transfusion and even assess the possibility of eradicating the disease at a cytogenetic/morphologic level. In the present trial and given the characteristics of the patients, we have chosen the option of supplying Lenalidomide at a dose of 5mg/day. The option of considering a lower dose to the one currently considered as "standard" (10mg/day) is to reduce toxicity, mainly hematologic, in patients who do not receive treatment normally. A dose with lower toxicity has been chosen which has revealed itself efficient.

Main efficiency objective:

•To assess if treatment with Revlimid (Lenalidomide) extends the period until the progression to myelodysplastic syndrome del(5q) considered as transfusion independent, documented verification that the patient suffering from anemia due to MDS requires transfusion of at least 2 UCH/56 days (2 months) with a minimum follow up of 112 days (4 months). Revlimid will be compared to the current standard treatment for patients with low risk myelodysplastic syndrome associated with the loss of 5qwithout transfusion dependent anemia, which is the therapeutic abstention and monitoring until its progression.

Secondary efficiency objectives:

* Erythroid response according to the Criteria of the myelodysplastic syndrome International Work Team 2006).
* Duration of the red blood cells transfusion independency (defined as the number of days elapsed between the randomization and the first transfusion after this period free of transfusions).
* Change of hemoglobin concentration (Hb) in relation to baseline levels of patients who show erythroid response.
* Variation in platelets absolute count in relation to baseline levels.
* Variation in neutrophils absolute count in relation to baseline levels.
* Cytogenetic response according to the Criteria of the myelodysplastic syndrome International Work Team.
* Bone marrow response according to the Criteria of the myelodysplastic syndrome International Work Team.
* To assess the safety and tolerance of the Lenalidomide scheme, measured according to the incidence of clinical and laboratory toxicity.
* Global survival, Event Free Survival and Rate of Transformation to Acute Leukemia.
* Time from diagnose to transfusion independence.

Main safety objective:

Safety (type, frequency and severity \[Criteria of normal terminology of adverse reactions of the National Cancer Institute (NCI CTCAE) version 3.0\] of adverse reactions (AR)and list of the AR with Lenalidomide.
