| E.2.1 | Main objective of the trial |
Phase Ib
To assess the safety and tolerability, identify dose-limiting toxicities (DLT) and determine the maximum tolerated dose (MTD)/recommended phase 2 dose (RP2D) of APG-2575, administered orally as monotherapy or in combination with rituximab or acalabrutinib in patients with relapsed and/or refractory CLL/SLL.
Phase II
To assess efficacy of APG-2575 alone or in combination with other therapeutic agents such as rituximab or, acalabrutinib in patients with relapsed and/or refractory CLL/SLL. (Efficacy assessment parameters will include: ORR, CR, PR, PR-L, DOR, PFS, OS, MRD by 8-color flow cytometry with a minimum sensitivity of 10-4 (0.01%) in peripheral blood and bone marrow, time to CR and/or MRD negativity.) |
Ib. fázis
Fel szeretnénk mérni az APG-2575 biztonságosságát és tolerálhatóságát, azonosítani szeretnénk a dóziskorlátozó toxicitásait (DLT-it), és meg szeretnénk határozni a még tolerálható maximális adagját (MTD-jét)/a II. fázisban javasolt adagját (RP2D), orálisan, monoterápiaként, illetve rituximabbal vagy akalabrutinibbel kombinálva alkalmazva kiújult és/vagy refrakter CLL-ben/SLL-ben szenvedő betegeknél.
II. fázis
Fel szeretnénk mérni az önmagában vagy más terápiás szerekkel, például rituximabbal vagy akalabrutinibbel alkalmazott APG-2575 hatásosságát kiújult és/vagy refrakter CLL-ben/SLL-ben szenvedő betegeknél. (A hatásosság értékelésének paraméterei: ORR, CR, PR, PR-L, DOR, PFS, OS, MRD 8 színű áramlásos citometriával, legalább 10−4 (0,01%) szenzitivitás mellett, perifériás vérben és csontvelőben; CR-ig és/vagy MRD-negativitásig eltelt idő.) |
|
| E.2.2 | Secondary objectives of the trial |
1. Determine the pharmacokinetics (PK) of APG-2575 when administered as: a single agent or in combination with, a) rituximab, b) acalabrutinib (acalabrutinib PK will be compared with historical experience).
2. To evaluate the relationship between exploratory and prognostic biomarkers (including BH3 profiling) for CLL /SLL and response to APG-2575 |
1. Meg szeretnénk határozni az önmagában, illetve a) rituximabbal, b) akalabrutinibbel kombinálva alkalmazott APG-2575 farmakokinetikáját (az akalabrutinib farmakokinetikáját a korábbi tapasztalattal vetjük össze).
2. Ki szeretnénk értékelni az összefüggést a CLL/SLL feltáró és prognosztikai biomarkerei (beleértve a BH3-profilozást), valamint az APG-2575-re adott válasz között, a készítményt önmagában, illetve rituximabbal vagy akalabrutinibbel kombinációban alkalmazva. |
