Population: Patients who received study treatment and were assessed by MRI every 8 weeks.

Time (number of months) from first documented evidence of overall Complete Response (CR) or Partial Response (PR) until time of first documented disease progression or death due to any cause (for individual patients). Progression as defined by RECIST 1.1 (Response Evaluation Criteria In Solid Tumors) is a ≥ 20% increase in the sum of the diameters of target lesions, taking as a reference, the smallest sum of diameters recorded since the treatment started (e.g. percent change from nadir, where nadir is defined as the smallest sum of diameters recorded since treatment start). In addition, the sum must have an absolute increase from nadir of 5mm.

The Functional Assessment of Cancer Therapy-Brain (FACT-Br) is used to measure general quality of life (QOL) that reflects symptoms or problems associated with brain malignancies across 5 scales. The brain subscale is usually used along with the core (general) questionnaire that includes 27 items. The measure yields information about total QOL, as well as information about the dimensions of physical well-being, social/family well-being, emotional well being, functional well-being, and disease-specific concerns. Patients rate all 5 items using a five-point Likert scale ranging from 0 "not at all" to 4 "very much." Overall, higher ratings suggest higher QOL. Items are totaled to produce the following subscales, along with an overall QOL score: physical well-being (7 items); social/family well-being (7 items); emotional well-being (6 items); functional well-being (7 items); and concerns relevant to patients with brain tumors (23 items). Scoring range is 0-200.
