General information about the trial
|
|||
Main objective of the trial |
The primary objective of the phase I (dose escalation of ibrutinib) is to establish the recommended phase II dose (RP2D) of ibrutinib in combination with bortezomib in patients with relapsed or refractory Mantle cell Lymphoma (MCL).
The primary objective of the phase II is to define the efficacy of ibrutinib in combination with bortezomib in patients with relapsed or
refractory Mantle cell Lymphoma.
|
||
Protection of trial subjects |
Protection of trial subjects was ensured by Safety Monitoring, i.e. assessment of adverse events, serious adverse events, adverse drug reactions, and the continous assessment of laboratory values and vital signs.

Recruitment
|
|||||||||||||||||||||
Recruitment details |
The recruitment phase started on 31-Aug-2015 and and ended on 30-Mar-2021 after the recruitment of 58 patients (including three patients being enrolled in Phase I, receiving the lower study drug dose and thus not passing over to Phase II). Patients were enrolled at three sites in Germany, three sites in Italy and nine sites in Switzerland. | ||||||||||||||||||||
Pre-assignment
|
|||||||||||||||||||||
Screening details |
Eligibility criteria of a patient were checked by the investigator. Once a patient fullfils all inclusion criteria and not any of the exclusion criteria, he/she was enrolled. One patient was deemed a screening failure and not included into the trial. | ||||||||||||||||||||

Substantial protocol amendments (globally) |
|||
Were there any global substantial amendments to the protocol? Yes | |||
Date |
Amendment |
||
18 Dec 2015 |
Substantial protocol amendment in order to remove the PET measurements for bone marrow assessment. Due to new discussions with experts for PET imaging it was clarified that the bone marrow involvement for patients with MCL can only be analyzed via PET/CT for a certain subgroup of patients (focal FDG uptake in the bone marrow) and not for the whole patient population of the trial. The PET measurements for bone marrow assessment were therefore deleted in the amended protocol. |
||
23 Dec 2016 |
Substantial protocol amendment in order to update the risk section of the protocol due to the update of the investigator brochure of ibrutinib. In addition, the inclusion criterion 6.1.3 was changed from maximum 2 previous treatment lines to any treatment line. The duration of combination treatment was also updated allowing patients who received at least 4 cycles of ibrutinib and bortezomib (instead of 6 cycles) to proceed with maintenance therapy. |
||
22 Jun 2018 |
Substantial protocol amendment in order to update the adverse event reporting, the implementation of the adapted serious adverse event reporting form and the adaptation of the uncommon side effects section in the protocol due to the release of the new investigator brochure of ibrutinib. |
||
11 Mar 2019 |
Due to low accrual, a substantial amendment has been issued in order to allow an interim efficacy analysis once the first 31 patients of phase II have completed the combination therapy. The continuation of the trial should have depended on the outcome of this analysis. |
||
Interruptions (globally) |
|||
Were there any global interruptions to the trial? No | |||
Limitations and caveats |
|||
Limitations of the trial such as small numbers of subjects analysed or technical problems leading to unreliable data. | |||
Primary and final analysis was performed after all patients in the Phase II FAS completed combination therapy. Originally, final analysis was planned after trial termination (LPLV). However, the trial was terminated after primary analysis. |
