Trial Information

Third-line Therapy of Multiple Myeloma With Lenalidomide in Combination With Pioglitazone, Dexamethasone and Metronomic Low-dose Chemotherapy With Treosulfan

Inclusion Criteria:

- At least 18 years of age

- Must be able to adhere to the study visit schedule and other protocol requirements.

- Must be diagnosed with multiple myeloma that is progressing or has relapsed with
progressive disease after at least two different anti-myeloma treatments (including
lenalidomide in one schedule for phase II part only)

- In case of patients that have progressive disease after complete remission during
preceding treatment: Serum monoclonal paraprotein (M-protein) level

≥0.5 g/dL for IgG, IgA myeloma and ≥0.05 g/dL for IgD myeloma or urine M-protein
level ≥ 0.2 g excreted in a 24-hour collection sample or In case of progressive
disease without complete remission during preceding treatment: > 25% increase of
serum monoclonal paraprotein or urine M-protein in comparison to the preceding
monoclonal paraprotein (M-protein)nadir in serum /urine M-protein nadir in a 24 hour
collection sample

- Subjects must have been previously treated with lenalidomide for the phase II part.
Any first- and second-line treatment is allowed for the phase I part. Phase I study
inclusion independent of pre-treatment in 1st line.

- Sufficient bone marrow function: neutrophils ≥ 2x109/l, hemoglobin ≥10 g/dl, and
platelets ≥ 100x109/l

- Eastern Cooperative Oncology Group (ECOG) performance status score of 0, 1, or 2 (see
Post Text Supplement 2).

- Subjects must discontinue all anti-myeloma drug or non-drug therapy prior to the
first dose of study drug (at least 4 weeks).

- Required laboratory results:

1. Liver function: Total bilirubin < 1.5 times of upper limit of local institution
(ULN), SGPT, SGOT ≤ 2.5 times of upper limit of local institution .

2. Renal function: serum creatinine ≤ 1.5 ULN c)PT-INR/PT <1.5 ULN

- Normal cardiac function

- Patients with prior thromboembolic event with adequate anticoagulation

- Life expectancy at least 3 months

- Written informed consent of the patient prior to screening procedures

- Patient must be available for treatment and follow-up

- Any previous surgery must have taken place more than 4 weeks prior to inclusion

- Previous radiation therapy must have involved less than 25% of bone marrow, and must
have been completed more than 4 weeks prior to inclusion.

- Able to take acetylsalicylic acid (ASA) 100 mg daily as prophylactic anticoagulation
(patients intolerant to ASA may use low molecular weight heparin). Patients at high
risk for thromboembolic events should receive low molecular heparin. Patients with
history of thromboembolic event should pursue their ongoing anticoagulants (e.g.
phenprocoumon, warfarin, heparin) or receive another adequate prophylaxis, at least

- Female subjects of childbearing potential† must:

- Understand that the study medication has a teratogenic risk

- Agree to use, and be able to comply with, effective contraception without
interruption, 4 weeks before starting study drug, throughout study drug therapy
(including dose interruptions) and for 4 weeks after the end of study drug
therapy, even if she has amenorrhoea.This applies unless the subject commits to
absolute and continued abstinence confirmed on a monthly basis. The following
are effective methods of contraception*

- Implant**

- Levonorgestrel-releasing intrauterine system (IUS)**

- Medroxyprogesterone acetate depot

- Tubal sterilization

- Sexual intercourse with a vasectomised male partner only; vasectomy must be confirmed
by two negative semen analyses

- Ovulation inhibitory progesterone-only pills (i.e., desogestrel)

- Because of the increased risk of venous thromboembolism in patients with
multiple myeloma, combined oral contraceptive pills are not recommended. If a
subject was using combined oral contraception, she must switch to one of the
methods above. The increased risk of VTE continues for 4 to 6 weeks after
stopping combined oral contraception.

- prophylactic antibiotics should be considered at the time of insertion
particularly in patients with neutropenia due to risk of infection

- Agree to have a medically supervised pregnancy test with a minimum sensitivity of 25
mIU/ml not more than 3 days from the start of study medication once the subject has
been on effective contraception for at least 4 weeks. This requirement also applies
to women of childbearing potential who practice complete and continued abstinence.

- Agree to have a medically supervised pregnancy test every 4 weeks including 4 weeks
after the end of study treatment, except in the case of confirmed tubal
sterilization. These tests should be performed not more than 3 days before the start
of next treatment. This requirement also applies to women of childbearing potential
who practice complete and continued abstinence

- Male subjects must

- Agree to use condoms throughout study drug therapy, during any dose interruption
and for one week after cessation of study therapy if their partner is pregnant
or is of childbearing potential and has no contraception.

- Agree not to donate semen during study drug therapy and for one week after end
of study drug therapy.

- All subjects must

- Agree to abstain from donating blood while taking study drug therapy and for one
week following discontinuation of study drug therapy.

- Agree not to share study medication with another person and to return all unused
study drug to the investigator † A female subject or a female partner of a male
subject is considered to have childbearing potential unless she meets at least
one of the following criteria: Age ≥50 years and naturally amenorrhoeic for ≥ 1
year (amenorrhoea following cancer therapy does not rule out childbearing
potential), premature ovarian failure confirmed by a specialist gynaecologist,
previous bilateral salpingo-oophorectomy or hysterectomy, XY genotype, Turner's
syndrome or uterine agenesis.

Exclusion Criteria:

- Patients who require vitamin K antagonists except for low dose (INR ≤ 2,5)

- Known hypersensitivity to dexamethasone. Prior history of uncontrollable side effects
to dexamethasone therapy.

- Active infection > grade 2 NCI-CTC version 3.0

- Known diagnosis of HIV, hepatitis B, or hepatitis C infection.

- Severe, unstable, or uncontrolled medical disease which would confound diagnoses or
evaluations required by the protocol, including cardiac insufficiency (NYHA I -IV)
uncontrolled diabetes, chronic hepatic or renal disease, active uncontrolled
infection and chronic inflammatory intestinal disease, autoimmune diseases.

- Prior radiation therapy > 25% of bone marrow

- Regular blood transfusions

- Treatment with other experimental substances within 30 days before study start

- Participation in another clinical trial within 30 days before study start or during
the trial

gastric ulcer, present to the extent that it might interfere with oral intake and

years prior to study entry except cervical carcinoma in situ or adequately treated
basal cell carcinoma
