lenalidomide. Patients with AML should have failed any prior induction therapy or
have relapsed after prior therapy, or be previously untreated and unable or unwilling
to receive conventional chemotherapy (e.g., patients age >/=65 years). Patients with
MDS or CMML who received therapy with a hypomethylating agent and progress to AML are
eligible at the time of diagnosis of AML regardless any prior therapy for AML. The
WHO classification will be used for AML. Patients with MDS, CMML or AML who have
received no prior therapy are eligible if not candidates to receive or refuse
standard therapy.

2. Patients must have evidence of FLT3 activating mutations.

3. Age >/= 18 years

4. ECOG Performance Status
5. Adequate liver (bilirubin ULN) function

6. Patients must provide written informed consent.

7. Patients must have been off chemotherapy for 2 weeks prior to entering this study,
unless there is evidence of rapidly progressive disease, and must have recovered from
the toxic effects of that therapy to at least grade 1. Use of hydroxyurea for
patients with rapidly proliferative disease is allowed before the start of study
therapy and for the first four weeks on therapy.

8. Women of childbearing potential must practice contraception. Women considered not of
childbearing potential include any of the following: no menses for at least 5 years
or menses within 5 years but amenorrheic for at least 2 months and luteinizing
hormone (LH) and follicular stimulating hormone (FSH) values within normal range
(according to definition of postmenopausal for laboratory used) or bilateral
oophorectomy or radiation castration and amenorrheic for at least 3 months. Females
of childbearing potential: Recommendation is for 2 effective contraceptive methods
during the study. Adequate forms of contraception are double barrier methods (condoms
with spermicidal jelly or foam and diaphragm with spermicidal jelly or foam), oral,
depo provera, or injectable contraceptives, intrauterine devices, and tubal ligation.

9. **continued from above: Male patients with female partners who are of childbearing
potential: Recommendation is for male and partner to use at least 2 effective
contraceptive methods, as described above, during the study.

10. Sexually active males should use a condom during intercourse while taking drug and
for 3 months after stopping midostaurin medication. They should not father a child in
this period. A condom is required to be used also by vasectomized men in order to
prevent delivery of the drug via seminal fluid .

11. Negative urine or serum pregnancy test within 2 weeks.

Exclusion Criteria:

1. Patients with known allergy or hypersensitivity to PKC412, mannitol or 5-azacytidine,
or any of their components.

2. Patients who have received any treatment of midostaurin prior to study entry.

3. Patients with known impairment of gastrointestinal (GI) function or GI disease that
may significantly alter the absorption of PKC412.

4. Patients who demonstrated primary resistance to any FLT3 inhibitor or who relapsed
while on therapy with a FLT3 inhibitor.

5. Patients with any other known disease (except carcinoma in-situ) concurrent severe
and/or uncontrolled medical condition (e.g. uncontrolled diabetes with fasting
glucose > 200 mg/dl despite optimal management, cardiovascular disease including
congestive heart failure (NYHA Class III or IV), myocardial infarction within 6
months and poorly controlled hypertension with systolic > 160 mmHg and diastolic >
100 mmHg, chronic renal disease, or active uncontrolled systemic infection) which
could compromise participation in the study.

6. Patients with a known confirmed diagnosis of HIV infection or active viral hepatitis.
HIV patients not on specific antiretroviral therapy are eligible for participation.

7. Patients who have had any major surgical procedure within 14 days of Day 1.

8. Patients unwilling or unable to comply with the protocol.

9. Patients with known advanced malignant disease of the central nervous system.

10. Impaired cardiac function including any of the following: Screening ECG with a QTc >
470 msec; Patients with congenital long QT syndrome; History or presence of sustained
ventricular tachycardia; Any history of ventricular fibrillation or torsades de
pointes; Bradycardia defined as HR < 50 bpm; Right bundle branch block + left
anterior hemiblock (bifascicular block); Patients with myocardial infarction or
unstable angina < 6 months prior to starting study drug; CHF NY Heart Association
class III or IV; Patients with an ejection fraction < 50% assessed by MUGA or ECHO
scan within 14 days of Day 1.
