Clinical Trial Summary

The primary objective of the study is to assess the pharmacokinetic (PK) similarity of Boehringer Ingelheim (BI) 695500 vs. rituximab (MabThera®) in previously untreated patients with low tumor burden follicular lymphoma (LTBFL).

The secondary objective of the study is to evaluate the pharmacodynamics (PD), safety, and anti-tumor activity of BI 695500 vs. rituximab (MabThera®), as well as the presence of anti-drug antibodies (ADAs).

• Adequate hematological function (unless abnormalities are related to lymphoma infiltration of the bone marrow) within 28 days prior to randomization, including:

• - hemoglobin =9.0 g/dL (=5.6 mmol/L).

• - absolute neutrophil count =1.5 × 10^9/L.

Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) <3 x upper limit of normal (ULN) (<5 x ULN is acceptable if abnormalities are thought to be related to hepatic infiltration by FL).

• For participants of reproductive potential (males and females), use of a medically acceptable method of contraception during the trial, i.e., a combination of 2 forms of effective contraception (defined as hormonal contraception, intrauterine device, condom with spermicide, etc.). Females of childbearing potential (includes tubal ligation) and males with female partners of childbearing potential must also agree to use an acceptable method of contraception (see above) for 12 months following completion or discontinuation from the trial medication.

• Receipt of a live/attenuated vaccine within 12 weeks prior to the Screening Visit.

• Prior treatment with BI 695500 and/or rituximab.

• Patients who received any prior therapy using monoclonal antibodies will be excluded; this does not apply to other biological drugs such as growth factors or anticoagulants.

• Treatment within a clinical trial within 4 weeks prior to initiation of trial treatment. Patients who have received treatment with a drug that has not received regulatory approval for any indication within 4 weeks or a minimum of 5 half-lives, whichever is longer, of the initial dose of trial medication.

• Any other co-existing medical or psychological condition(s) that will preclude participation in the trial or compromise ability to give informed consent and/or comply with study procedures.

• Pregnancy or breast feeding. For women of childbearing potential, a positive serum pregnancy test at the Screening Visit.

• Patients who have significant cardiac disease, including but not limited to congestive heart failure of Class III or IV of the New York Heart Association (NYHA) classification; uncontrolled angina or arrhythmia; any uncontrolled or severe cardiovascular or cerebrovascular disease; or uncontrolled hypertension.
