BIBF 1120 and RAD001 in Solid Tumors - Phase I

A phase I trial to evaluate the safety and tolerability of combined BIBF 1120 and RAD001 in solid tumors and to determine the maximum tolerated dose (MTD) of the combination

Inclusion criteria

• Histologically or cytologically proven solid tumor disease after failure of standard therapy regimen(s)
• Age > 18 years.
• ECOG performance status 0 to 1.
• Life expectancy of at least 12 weeks.
• Subjects with at least one measurable (CT or MRI) lesion.
• Adequate bone marrow, liver and renal function as assessed by the following laboratory requirements conducted within 7 days prior to screening:

• Hemoglobin > 9.0 g/dl
• Absolute neutrophil count (ANC) >1,500/mm3
• Platelet count ³ 100,000/μl
• Total bilirubin within normal limits
• ALT and AST < 1.5 x upper limit of normal ( or < 2.5 x upper limit of normal in patients with liver involvement)
• PT-INR/PTT < 1.5 x upper limit of normal [Patients who are being therapeutically anticoagulated with an agent such as coumadin or heparin will be allowed to participate provided that no prior evidence of underlying abnormality in these parameters exists.]
• Serum creatinine < 1.5 x upper limit of normal or creatinine clearance (CrCl) ≥ 50 ml/min calculated by either Cockcroft-Gault or by 24 hours urine collection
• More than 14 days since previous chemotherapy, radiotherapy and surgery
• Negative urine or serum HCG in women of childbearing potential
• Signed and dated informed consent before the start of specific protocol procedures

Exclusion criteria

• Limited number of prior lines of treatment (including surgery and radiotherapy, if part of the standard therapy of the respective tumor entity)
• Prior treatment with BIBF 1120 or any other VEGFR inhibitor (bevacizumab is allowed)
• Prior treatment with RAD001 or any other mTOR inhibitor
• Known hypersensitivity to the trial drugs, to their excipients or to contrast media
• Chemo-, hormono-, radio-(except for brain and extremities) or immunotherapy or therapy with monoclonal antibodies or small tyrosine kinase inhibitors within the past 2 weeks prior to treatment with the trial drugs
• Persistence of clinically relevant therapy related toxicity from previous chemo and/or radiotherapy
• Active brain metastases (e.g. stable for <4 weeks, no adequate previous treatment with radiotherapy, symptomatic, requiring treatment with anticonvulsants; dexamethasone therapy will be allowed if administered as stable dose for at least one month before trial drug administration) or leptomeningeal metastases (documented by lumbar puncture)
• History of cardiac disease: congestive heart failure >NYHA class 2; active coronary artery disease (CAD), (MI more than 6 mo prior to study entry is allowed); cardiac arrhythmias requiring antiarrhythmic therapy (beta blockers or digoxin are permitted) or uncontrolled hypertension
• Impairment of gastrointestinal function or gastrointestinal disease that may significantly alter the absorption of BIBF1120 or RAD001 (e.g. ulcerative disease, uncontrolled nausea, vomiting, diarrhea, malabsorption syndrome or small bowel resection)
• History of HIV infection or previously seropositive for the virus
• History of Hepatitis B or/and C or previously seropositive for the Hepatitis B or/and C virus
• Radiographic evidence of cavitary or necrotic tumors
• Centrally located tumors with radiographic evidence (CT or MRI) of local invasion of major blood vessels
• Treatment with other investigational drugs or treatment in another clinical trial within the past 30 days before start of therapy or concomitantly with the trial
• Patients with seizure disorder requiring enzyme-inducing antiepileptics
• Therapeutic anticoagulation (except low-dose heparin and/or heparin flush as needed for maintenance of an indwelling intravenous devise) or antiplatelet therapy (except for low-dose therapy with acetylsalicylic acid ≤325mg per day)
• Major injuries within the past 10 days prior to start of study treatment with incomplete wound healing and/or planned surgery during the on-treatment study period
• Evidence or history of bleeding diasthesis or thrombosis, and known inherited predisposition to bleeding or thrombosis
• Proteinuria CTC AE grade 2 or greater
• Active serious infections
• Patients undergoing renal dialysis
• Previous or concurrent cancer that is distinct in primary site or histology from the cancer being evaluated in this study EXCEPT cervical carcinoma in situ, treated basal cell carcinoma, superficial bladder tumors [Ta, Tis & T1] or any cancer curatively treated > 3 years prior to study entry
• Serious illness or concomitant non-oncological disease such as neurologic, psychiatric, infectious disease or active ulcers (gastrointestinal tract, skin) or laboratory abnormality that may increase the risk associated with study participation or study drug administration and in the judgment of the investigator would make the patient inappropriate for entry into the study
• Patients who are sexually active and unwilling to use a medically acceptable method of contraception (e.g. such as implants, injectables, combined oral contraceptives, some intrauterine devices or vasectomized partner for participating females, condoms for participating males) during the trial and for at least three months after end of active therapy
• Pregnancy or breast feeding
• Psychological, familial, sociological or geographical factors potentially hampering compliance with the study protocol and follow-up schedule
• Active alcohol or drug abuse
