An Open Label Phase I Dose Escalation Trial of Intravenous BI 6727 (Volasertib)in Combination With Oral BIBW 2992 (Afatinib) in Patients With Advanced Solid Tumours

Phase 1CompletedNCT01206816

Boehringer Ingelheim57 enrolled

Overview

The primary objective of the current study is to investigate the Maximum Tolerated Dose (MTD) in terms of safety and tolerability of the combination of BI 6727 with BIBW 2992, in patients with advanced or metastatic solid tumours. Dosages of both BI 6727 and BIBW 2992 will be varied to establish the MTD of the combination. Two combination treatment schedules will be tested, the MTD of each combination will be determined. Secondary objectives are the exploration of pharmacokinetics, overall safety and preliminary efficacy.

Number of Participants With Dose Limiting Toxicities (DLT)

MTD was defined on the basis of DLTs occuring during Cycle 1 of the dose escalation part in each of the 2 treatment schedules. DLTs were defined as drug related based on Common Terminology Criteria for AE's (CTCAE) Grade(G) :1) G4 neutropenia (ANC, including bands, \<500/mm³) for more than 7 days, 2) G3 or 4 neutropenia associated with fever \>38.5° C (febrile neutropenia),3) Neutropenic infection G ≥3, 4) G4 thrombocytopenia or G3 thrombocytopenia associated with bleeding requiring whole blood transfusion.5) Non-haematological G ≥3 toxicity excluding: (a) untreated G3 diarrhoea, (b) untreated G3 nausea and/or vomiting, (c) untreated G3 rash. 6) G2 increase in AST and/or ALT in conjunction with an elevated bilirubin level of G ≥2, 7) G2 nausea and/or vomiting despite optimal supportive/antiemetic treatment for at least 7consecutive days. 8) G2 diarrhoea for 2 or more consecutive days despite antidiarrhoeal medication/hydration, 9) Decrease in left ventricular function G ≥2.

Time frame: 22 Days

Maximum Tolerable Dose (MTD) of Two Combination Therapy of Volasertib and Afatinib.

Maximum Tolerable Dose (MTD) was determined by dose escalation for volasertib and afatinib. The "3 + 3 design with de-escalation" for both the Schedules A and B. Patients were sequentially allocated to the dose cohorts. Apart from allocation to the treatment schedules, escalation and/or de-escalation to determine the MTD occurred independently within the 2 dose schedules. Cohorts of 3 patients were to be treated at the starting dose levels according to the treatment schedule. Before entering patients at a higher dose level, all patients at the previous dose level combination had to complete at least the initial cycle of 21 days.

Time frame: MTD was assessed during the first cycle of combination of Volasertib and Afatinib therapy (22 days)

Secondary Outcomes

Number of Patients With Drug-related Adverse Events According to Common Terminology Criteria for Adverse Events (CTCAE) Criteria v 3.0

Number of patients with investigator defined drug-related adverse events according to Common Terminology Criteria for Adverse Events (CTCAE) criteria v 3.0

Time frame: After the first drug administration until 28 days after the last drug administration, up to 413 days.

Number of Patients With Objective Response (OR)

Objective tumor response based on response evaluation criteria in solid tumors (RECIST) version 1.1. OR is defined as complete response (CR) or partial response (PR). As Per Response Evaluation Criteria in Solid Tumors Criteria (RECIST v1.0) for target lesions and assessed by using appropriate radiology techniques: Complete Response (CR), disappearance of all target lesions; Partial Response (PR), \>=30% decrease in the sum of the longest diameter of target lesions.

Time frame: Tumor assessment was performed at screening and at the end of every 3 treatment cycle (ie every 9 weeks of treatment).

Number of Patients With Best Overall Response.

Best overall response based on response evaluation criteria in solid tumors (RECIST) version 1.1. Best overall response is defined as complete response, partial response, stable disease, progressive disease or not evaluable. As Per Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.0) for target lesions and assessed by using appropriate radiology techniques: Complete Response (CR), disappearance of all target lesions; Partial Response (PR), \>=30% decrease in the sum of the longest diameter of target lesions; progression, as a 20% increase in the sum of the longest diameter of target lesions, or a measurable increase in a non-target lesion, or the appearance of new lesions; Stable Disease (SD), neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for disease progression.

Time frame: Tumor assessment was performed at screening and at the end of every 3 treatment cycle (ie every 9 weeks of treatment).

Number of Patients With Disease Control

Disease control based on response evaluation criteria in solid tumors (RECIST) version 1.1. Patients who had a best overall tumour response of complete response (CR), partial response (PR) or stable disease (SD) were assessed to show disease control. As Per Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.0) for target lesions and assessed by using appropriate radiology techniques: Complete Response (CR), disappearance of all target lesions; Partial Response (PR), \>=30% decrease in the sum of the longest diameter of target lesions; Stable Disease (SD), neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for disease progression.

Time frame: Tumor assessment was performed at screening and at the end of every 3 treatment cycle (ie every 9 weeks of treatment).
