Trial Information

A Pilot Study of the Combination of Lenalidomide (Revlimid®) With Two Different Dose Levels of Short Term Administration of Recombinant Human Stem Cell Factor (rhSCF; Ancestim) for Myelodysplasia.

Aim: The primary objective is to assess the safety of Revlimid in combination with Ancestim
in patients with symptomatic myelodysplasia. The secondary objectives are: Duration of
response and assessment of changes in gene expression profile of bone marrow samples from
patients undergoing such treatment.

Potential Significance: Myelodysplastic syndromes (MDS) are malignant hematopoietic stem
cell disorders. Prognosis can be estimated by use of the International Prognostic Scoring
System (IPSS) which divides patients into low, intermediate-1, intermediate-2, and high-risk
groups with corresponding median survival times of 5.7 years, 3.5 years, 1.2 years, and 0.4
years, respectively. There is currently no standard treatment for MDS and management is
often purely symptomatic with transfusion of blood products and antibiotic treatment of

A recent phase II study however has shown significant response rates with Revlimid as a
single agent in patients with MDS. The total response rate was 56%. The effects of Revlimid
and SCF on hematopoietic progenitors cells were examined in vitro. RhSCF and Revlimid were
shown to be synergistic in stimulating the proliferation of hematopoietic progenitor cells
and their precursors in vitro, thereby forming the rationale for this study.

Research Plan: This is a single-centre, open label, single-arm, non-comparative study, in
which 25 patients will be enrolled. The study will include patients who meet all the
inclusion and none of the exclusion criteria, as per the respective protocol section.

The patients will be enrolled sequentially to receive 2 different dose levels of Ancestim
with a fixed dose of Revlimid. This will determine the feasibility and tolerability of the
combination of Revlimid and Ancestim. Patients will start with an 8 week course of single
agent Revlimid as 10mg daily oral treatment day 1-21 in a 28 day cycle. If patients do not
achieve a complete remission on single agent Revlimid they will start on Ancestim s.c.
injections. Two dose levels of Ancestim (10 and 20 mcg/kg s.c. daily for 7 days) will be

Safety: Safety will be assessed by the reporting of adverse events (starting with the first
study-related procedure, during treatment, and for a period of 60 days following
discontinuation of treatment). The intensity of the adverse events will be assessed using
National Cancer Institute common toxicity criteria. All adverse events will be recorded on
the case report forms (CRFs). Furthermore, assessments of physical (including neurological
/ peripheral neurological) examinations, vital signs measurements, and haematology and
clinical chemistry tests will be used to monitor safety. Clinically relevant changes in
laboratory safety tests, vital signs, and physical examinations will be recorded as adverse
events. The adverse event sections of the CRFs will be submitted to a representative of the
sponsor at the end of each treatment cycle. Serious adverse events will be reported as they
occur, on forms provided by the sponsor.

Efficacy: Response to treatment will be assessed according to the guidelines of the
international working group to standardize response criteria for myelodysplastic syndromes.
This will be done on bone marrow biopsies (including cytogenetic analyses) and peripheral
blood counts. An additional scientific investigation will examine gene-expression profiles
of bone-marrow and blood samples at different time points and will try to correlate those
with response to treatment. Concomitant in-vitro studies will assess surrogate markers of

Statistical Methods: Adverse events, serious adverse events, transfusion requirements,
response data and Karnofsky performance status data will be summarized.

Inclusion Criteria:

1. Understand and voluntarily sign an informed consent form.

2. Age >18 years at the time of signing the informed consent form.

3. Able to adhere to the study visit schedule and other protocol requirements.

4. Patients must have a confirmed myelodysplastic syndrome regardless of subgroup
according to the WHO classification and their prognostic group. Patients with
treatment associated MDS are allowed on this study, however the number is restricted
to 10 (50% of patients anticipated to receive combination treatment). Patients with
CMML are eligible but restricted in number to up to 3 in total.

5. The patients must have either:

1. symptomatic anemia as defined as Hb < 10g/dl OR

2. transfusion-dependent anaemia as defined as requiring more than 4 units of
packed red blood cells over 8 weeks

6. All previous cancer therapy, including erythropoietin, thalidomide and other
experimental therapies must have been discontinued at least 4 weeks prior to
treatment in this study.

Exclusion Criteria:

1. Any serious medical condition, laboratory abnormality, or psychiatric illness that
would prevent the subject from signing the informed consent form.

2. Pregnant or lactating females.

3. Any condition, including the presence of laboratory abnormalities, which places the
subject at unacceptable risk if he/she were to participate in the study or confounds
the ability to interpret data from the study.

4. Use of any other experimental drug or therapy within 28 days of baseline.

5. Known hypersensitivity to thalidomide.

6. The development of erythema nodosum if characterized by a desquamating rash while
taking thalidomide or similar drugs.

7. Any prior use of Revlimid or SCF.

8. Concurrent use of other anti-cancer agents or treatments including erythropoietin.

9. Known positive for HIV or infectious hepatitis, type B or C.

10. Mast cell diseases (systemic mastocytosis, urticaria pigmentosa or diffuse cutaneous

11. History of severe anaphylaxis, asthma, recurrent urticaria, recurrent angiooedema

12. Known hypersensitivity against to Escherichia coli derived products.

13. Prior chemotherapy or stem cell transplantation for the treatment of myelodysplasia.
