| Percentage of Patients With Treatment-Emergent Adverse Events (TEAEs) in the Specified Categories Selected for Primary Endpoint Assessment | From baseline up to 18 weeks after the last dose of trial medication prior to the Switch Visit. Maximum duration of up to 32 treatment cycles + safety follow up (up to 82 weeks overall). | The primary safety endpoint of the trial was patients with any of the following selected adverse events (AEs): * Infusion reactions (anaphylactic/hypersensitivity/infusion-related reactions), * Thromboembolic events (arterial or venous), * Gastrointestinal perforations, * Hypertension, * Proteinuria, * Pulmonary hemorrhage * All hemorrhages (including pulmonary hemorrhages) * Wound-healing complications/abscess/fistulas * Posterior reversible encephalopathy syndrome * Ovarian failure. All AEs with an onset between start of treatment and end of the residual effect period (REP), a period of 18 weeks after the last dose of trial medication were considered for the primary safety analysis. Confidence interval was calculated using Wilson score method. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Duration of Response (DOR) as Assessed by Central Imaging Review | Tumor scans were performed at baseline then every ~8 weeks up to 34 weeks, then every ~12 weeks thereafter until confirmed disease progression. Analysis performed for the pre-switch period only; maximum duration of up to 32 treatment cycles (64 weeks). | DOR was the time from first documented Complete Response (CR) (CR is disappearance of all target lesions) or Partial Response (PR) (PR is at least a 30% decrease in the sum of diameters (SoD) of target lesions taking as reference the baseline sum diameters) until time of progression as assessed by central imaging review per Response evaluation criteria in solid tumors (RECIST) 1.1. RECIST is a set of published rules that define when tumors in cancer patients improve (respond), stay the same (stabilize) or worsen (progress) during treatment. DOR was calculated using the Kaplan-Meier technique. Confidence interval was calculated based on the Brookmeyer and Crowley method. |
| Time to Progression (TTP) as Assessed by Central Imaging Review | Tumor scans were performed at baseline then every ~8 weeks up to 34 weeks, then every ~12 weeks thereafter until confirmed disease progression. Analysis performed for the pre-switch period only; maximum duration of up to 32 treatment cycles (64 weeks). | TTP was defined as the time from first administration of trial medication to the date of tumor progression as assessed by central imaging review per RECIST 1.1 (RECIST is a set of published rules that define when tumors in cancer patients improve (respond), stay the same (stabilize) or worsen (progress) during treatment.). TTP was calculated using the Kaplan-Meier technique. Confidence interval was calculated based on the Brookmeyer and Crowley method. |
| Objective Response (OR) Rate as Assessed by Central Imaging Review | Tumor scans were performed at baseline then every ~8 weeks up to 34 weeks, then every ~12 weeks thereafter until confirmed disease progression. Analysis performed for the pre-switch period only; maximum duration of up to 32 treatment cycles (64 weeks). | OR rate was defined as the percentage of patients who achieved at least one visit response of CR (CR is disappearance of all target lesions) or PR (PR is at least a 30% decrease in the sum of diameters (SoD) of target lesions taking as reference the baseline sum diameters) after the start of treatment. The response criteria evaluation was carried out according to RECIST 1.1. RECIST is a set of published rules that define when tumors in cancer patients improve (respond), stay the same (stabilize) or worsen (progress) during treatment. Confidence interval was calculated using Wilson score method. The definition for OR (CR/PR) extends until disease progression/ death/ unacceptable toxicity/ end of the trial, whichever occurred earlier. However for Duration of response this censoring does not apply. Hence the apparent discrepancy. OR = CR + PR. |
| Overall Survival (OS) Time | From date of first dose of trial medication until last date of trial medication + 18 weeks (REP), up to a maximum of 32 treatment cycles + safety follow up (up to 82 weeks overall). | OS was defined as the time from first administration of trial medication until death from any cause. OS was calculated using the Kaplan-Meier technique. Confidence interval was calculated based on the Brookmeyer and Crowley method. |
| Progression-Free Survival (PFS) Time as Assessed by Central Imaging Review | Tumor scans were performed at baseline then every ~8 weeks up to 34 weeks, then every ~12 weeks thereafter until confirmed disease progression. Analysis performed for the pre-switch period only; maximum duration of up to 32 treatment cycles (64 weeks). | PFS was defined as the time from first administration of trial medication until disease progression as assessed by central imaging review or death due to any cause. Disease progression was assessed according to RECIST 1.1. RECIST is a set of published rules that define when tumors in cancer patients improve (respond), stay the same (stabilize) or worsen (progress) during treatment. Progression was defined as at least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study. In addition to the relative increase of 20%, the sum must also have demonstrated an absolute increase of at least 5 mm. PFS was calculated using the Kaplan-Meier technique. Confidence interval was calculated based on the Brookmeyer and Crowley method. |

Participant flow
Recruitment details
This was Phase IIIb, open-label, multicenter, multinational, single-arm trial. Patients with previously untreated metastatic colorectal cancer (mCRC) were enrolled. From 21December2017, Sponsor recommended that patients should be switched from BI 695502 to the reference product Avastin® as soon as it was available at the respective clinical site.
Pre-assignment details
All patients were screened for eligibility to participate in the trial. Patients attended specialist sites which would then ensure that they (the patient) met all strictly implemented inclusion/exclusion criteria. Patients were not to be randomised to trial treatment if any one of the specific entry criteria were violated.
Participants by arm

|---|---|
| BI 695502 All patients were to receive BI 695502 (5 milligrams per kilogram \[mg/kg\]) solution for intravenous (i.v.) infusion in combination with mFOLFOX6 chemotherapy every 2 weeks.
