Trial Information

Phase II Study of SOM230 LAR in Combination With Bortezomib and Dexamethasone in Patients With Refractory or Relapsed Multiple Myeloma

Inclusion Criteria:

- Patients must have histologically or cytologically confirmed symptomatic MM,
Salmon-Durie Stage II or III, International Staging System II or III, or fulfill the
CRAB criteria (see Appendix A, B). Patients should have previously been treated with
at least one cycle of bortezomib, after which the patient has shown progressive or
refractory disease. Finally, patients must meet at least one of the following
parameters of measurable disease:

- Bone marrow plasmacytosis with> 10% plasma cells, or sheets of plasma cells, or
biopsy proven plasmacytoma which must be obtained within 6 weeks prior to

- Measurable levels of monoclonal protein (M-protein): ≥ 1 g/dL on serum protein
electrophoresis (SPEP) or ≥ 200 mg of monoclonal light chain on a 24 hour urine
protein electrophoresis (UPEP) or involved FLC ≥ mg/dL (≥ 100 mg/L) which must
be obtained within 4 weeks prior to registration.

- Serum and urine M-protein levels should be determined by electrophoresis rather
than by quantitative immunoglobulin (Ig) measurement. Exceptions are made in
cases in which the M-spike value may be deemed to be unreliable ( e.g.
co-migrating M-spike). In these cases, quantitative Ig should be used. To assess
response and progression, however, SPEP values should only be compared to SPEP
values and quantitative Ig values only to quantitative Ig values.

- Patients must have received at least two prior anti-MM treatments. The prior
treatments must include at least one IMiD (thalidomide or lenalidomide) and
bortezomib. If patients are unable to tolerate thalidomide or lenalidomide they can
be included without prior IMiD treatment. Patients may be included if they did not
experience grade III neuropathy while on bortezomib. Patients may have previously
received autologous or peripheral blood stem cell transplantation.

- Minimum of four weeks since any major surgery, completion of radiation, or completion
of all prior systemic anticancer therapy. Exception: e.g. kyphoplasty,
vertebroplasty, local radiation therapy for symptomatic bone lesions (e.g.,
uncontrolled pain or high risk of pathologic fracture).

- Age ≥ 18 years.

- Life expectancy of greater than 12 weeks.

- Eastern Cooperative Oncology Group (ECOG) performance status ≤ 2 (Karnofsky ≥ 60%;
see Appendix B).

- Patients must have adequate organ and marrow function as defined below, obtained
within 4 weeks prior to registration:

- Hgb > 9 g/dL (which may be supported by transfusion or growth factors)

- Absolute neutrophil count > 1000 x 10-9/L

- Platelets ≥ 50,000 x 10-9/L

- PT/PTT < 1.5 x upper limits of normal (ULN)

- Total bilirubin ≤ 1.5 x (ULN)

- Hepatic:

Serum bilirubin ≤ 1.5 ULN

Aspartate aminotransferase and alanine aminotransferase

- 3 × ULN without liver metastases

- 5 × ULN if documented liver infiltration

- Renal:

Calculated creatinine clearance ≥40 ml/min according to the formula in Appendix D

- Cholesterol* ≤ 300 mg/dL

- Triglycerides (fasting)* ≤ 2.5 x ULN

- Fasting plasma glucose (FPG)** < 1.5X ULN for FPG or HbA1c ≤ 8% *In case one or both
of these thresholds are exceeded, the patient can only be included after initiation
of appropriate lipid lowering medication.

At the principle investigator's discretion, non-eligible patients can be re-screened after
adequate medical therapy has been instituted.

- Patients must not be pregnant or breast feeding and must have a negative pregnancy
test within 14 days of the administration of the first study treatment. Further, all
women of childbearing potential and sexually active males must agree to use a
medically effective contraception method throughout the treatment period and avoid
conception while participating in this study. Women must not be lactating. Post
menopausal patients and patients who had a bilateral oophorectomy need not take a
pregnancy test.

- Ability to understand and the willingness to sign a written informed consent
document. Patient must be informed of the investigational nature of this study.

- Patient should be able to swallow pills

Exclusion Criteria:

- Patients who have had chemotherapy, radiotherapy, or major surgery within 4 weeks
prior to entering the study or those who have not recovered from AEs due to
chemotherapy, radiotherapy, or major surgery completed more than 4 weeks prior to
registration. Exception: local radiation therapy for symptomatic bone lesions (e.g.,
uncontrolled pain or high risk of pathologic fracture).

- Patients with any of the following cardiac abnormalities:

- QTcF at screening > 450 msec

- History of syncope or family history of idiopathic sudden death

- Sustained or clinically significant cardiac arrhythmias

- Risk factors for Torsades de Pointes such as hypokalemia, hypomagnesemia,
cardiac failure, clinically significant/symptomatic bradycardia, or high-grade
AV block

- Concomitant disease(s) that could prolong QT such as autonomic neuropathy
(caused by diabetes, or Parkinson's disease), HIV, cirrhosis, uncontrolled
hypothyroidism or cardiac failure

- Concomitant medication(s) known to increase the QT interval

- Diabetic patients on antidiabetic medications whose HbA1C > 8%

- Patients currently receiving high dose systemic steroids for treatment of MM,
patients without prior bortezomib treatment, patients who received an investigational
agent within 5 half lives of the agent.

- Patients who require therapeutic (full) anticoagulation such as full dose low
molecular weight heparin or Coumadin with a goal INR of 2-3.

- Patients with known brain metastases (treated or not) will be excluded from this
clinical trial because of their poor prognosis and because they often develop
progressive neurologic dysfunction that would confound the evaluation of neurologic
and other AEs.

- Patients with a history of allergic reactions attributed to compounds of similar
chemical or biologic composition to SOM230 LAR and/or bortezomib or other agents used
in the study.

- Patients should not receive immunization with attenuated live vaccines during study
period or within 1 week of study entry.

- Patients with symptomatic cholelithiasis.

- Patients previously treated with sst or sst analogues.

- Patients with a second malignancy other than squamous/basal cell carcinoma of the
skin or in situ carcinoma of the cervix unless the tumor was curatively treated.

- Known HIV infection

- Patients who have any severe and/or uncontrolled medical conditions or other
conditions that could affect their participation in the study such as:

- Severely impaired lung function

- Any active (acute or chronic) uncontrolled disorders

- Nonmalignant medical illnesses that are uncontrolled or whose control may be
jeopardized by the study therapy

- Women who are pregnant or breast feeding, or women/men able to conceive and unwilling
to practice a medically effective method of birth control.

- Inability to comply with study and/or follow-up procedures or history of medical

- Patients who have a serious cardiac condition, such as myocardial infarction within 6
months, unstable angina, sustained ventricular tachycardia, ventricular fibrillation,
clinically significant bradycardia, history of syncope, family history of idiopathic
sudden death, QTc > 450 msec, advanced heart block or heart disease as defined by the
New York Heart Association Class III or IV. (See ECG guidelines, Section 8.0).

- Patients with non-secretory MM.

- Patients with prior allogeneic transplantation.
