This is a monocenter, single-arm, open label phase II trial evaluating the effect of SOM230 LAR in adult patients with inoperable primary thymoma and thymoma metastasis (Masaoka II-IVa). SOM230 LAR in a dosage of 60 mg is administered i.m. once every 4 weeks. The purpose of this trial is a proof of concept.
Primary Inoperable Thymoma
Local Recurrent Thymoma
Drug: SOM230 LAR
||Endpoint Classification: Efficacy Study
Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
||Efficacy of Medical Treatment With SOM230 LAR in Patients With Primary Inoperable Thymoma and/or With Local Recurrent Thymoma to Reduce Tumor Size
Primary Outcome Measures:
Secondary Outcome Measures:
- Resection status [ Time Frame: at least 6 months ] [ Designated as safety issue: No ]
To evaluate the resection status based on the categories R0, R1 and ≥ R2.
- Histological changes (necrosis) [ Time Frame: at least 6 months ] [ Designated as safety issue: No ]
- percentage of necrotic area
- degree of depletion (none, slight; moderate; marked) of immature T-cells (immunohistochemistry for CD1a, CD99, CD3 expression)
- change of T-cell subset composition as revealed by FACS analysis
- Safety [ Time Frame: at least 6 months ] [ Designated as safety issue: Yes ]
The assessment of safety will be based mainly on the frequency of Adverse Events and on the number of laboratory values that fall outside of pre-determined ranges.

|Ages Eligible for Study:
||18 Years and older
|Genders Eligible for Study:
|Accepts Healthy Volunteers:
- Male or female patients aged ≥18 years
- Diagnosis of thymoma as assessed by biopsy and/or szintigraphy
- Inoperability of thymoma or loco-regional metastases. Inoperability is defined as at least adherence of the tumor to the neighbored organs, suspicious to infiltrate neighbored organs or local metastasis so that R0 resection can not be expected and /or local recurrence of thymic tumor
- Tumor stage: Thymomas of all WHO based histological subtypes (WHO A, AB, B1, B2, B3) (Rosai, 1999; Travis 2004) at Masaoka stage II to IVa based on histological examination of resection specimens or core biopsies.
- Patients with and without thymoma associated paraneoplastic syndrome.
- Performance status 0,1, or 2 (ECOG)
- Patients for whom written informed consent to participate in the study has been obtained
- Patients having received radiolabeled somatostatin analogue therapy within the 6 months or any cytotoxic chemotherapy or interferon therapy within the 2 months prior to recording baseline symptoms
- Patients who have undergone major surgery/surgical therapy for any cause within 1 month or surgical therapy of loco-regional metastases within the last 3 months before recording baseline symptoms
- Patients who have received radiotherapy for any reason within the last 4 weeks and must have recovered from any side effects of radiotherapy before recording baseline symptoms
- Patients who are not biochemically euthyroid
- Diabetic patients on antidiabetic medications whose fasting blood glucose is poorly controlled as indicated by HbA1C > 8%
- Patients with symptomatic cholelithiasis
- Patients who have congestive heart failure (NYHA Class III or IV), unstable angina, sustained ventricular tachycardia, ventricular fibrillation, clinically significant bradycardia, advanced heart block or a history of acute myocardial infarction within the six months preceding enrollment
- Patients with QT related risk factor: QTcF at screening > 450 msec
- Patients with QT related risk factor: History of syncope or family history of idiopathic sudden death
- Patients with QT related risk factor:Sudden or clinically significant cardiac arrhythmias
- Patients with QT related risk factor: Risk factors for Torsades de Pointes such as hypokalemia, hypomagnesemia, cardiac failure, clinically significant / symptomatic bradycardia, or high-grade AV block
- Patients with QT related risk factor: 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
- Patients with QT related risk factor: Concomitant medication(s) known to increase the QT interval
- Patients with potassium <3.0 mmol/L at study entry, magnesium <0.4 mmol/L at study entry, calcium <1.75 mmol/L at study entry, family history of long QT syndrome, and concomitant medications known to prolong the QT interval. If the electrolyte abnormalities are corrected prior to study commencement, the patient may become eligible for the trial.
- Patients with liver disease such as cirrhosis, chronic active hepatitis or chronic persistent hepatitis with serum bilirubin > 1.5 X ULN, serum albumin < 0.67 X LLN, and/or ALT or AST more than 2 X ULN for patients without liver Confidential - 20 - Amended Clinical Study Protocol v01 / Track Changes Study No. CSOM230CIC01T metastases or ALT or AST more than 5X ULN for patients with documented liver metastases
- Patients with additional active malignant disease within the last five years (with the exception of basal cell carcinoma or carcinoma in situ of the cervix)
- Patients with the presence of active or suspected acute or chronic uncontrolled infection or with a history of immunocompromise, including a positive HIV test result (ELISA and Western blot). A HIV test will not be required; however, previous medical history will be reviewed
- Patients with abnormal coagulation (PT or APTT elevated by 30% above normal limits)
- Patients with WBC <2.5 X 109/L; Hgb <10 g/dL; PLT <100 X 109/L (patients with paraneoplastic pan-, leuco-, erythro- or thrombopenia can be included if this seems to be the only reason for pan-, leuco-, erythro- or thrombopenia)
- Known hypersensitivity to somatostatin analogues or any component of the pasireotide or octreotide LAR or s.c. formulations
- Patients who have any current or prior medical condition that may interfere with the conduct of the study or the evaluation of its results in the opinion of the investigator
- Female patients who are pregnant or lactating, or are of childbearing potential and not practicing a medically acceptable method of birth control. Female patients must use a secure method of contraception if sexually active and the partner should use a condom. If oral contraception is used, the patient must have been practicing this method for at least two months prior to enrollment and must agree to continue the oral contraceptive throughout the course of the study, and for three months after the study has ended. Male patients who are sexually active are required to use condoms during the study and for three months afterwards as a precautionary measure (available data do not suggest any increased reproductive risk with the study drugs). Female partners of these male patients should use a secondary barrier contraception.
- Patients who are currently part of or have participated in any clinical investigation with an investigational drug within 1 month prior to dosing
- Patients with a history of non-compliance to medical regimens or who are considered potentially unreliable or will not be able to complete the entire study
- Patient has received any other investigational agents within 28 days of first day of study drug dosing
- Abnormal clinical laboratory values considered by the investigator to be clinically significant and which could affect the interpretation of the study results
