Design outcomes
Primary
| Measure | Time frame |
|---|---|
| 1. Incidence, nature, and severity of all adverse events (AEs), serious adverse events (SAEs) and dose-limiting toxicities (DLTs): Common Terminology Criteria for Adverse Events (CTCAE) V5.0 will be assessed at each clinic visit and other assessments, including laboratory parameters, ECGs, and vital signs will be assessed at designated intervals during each cycle of treatment 2. Overall Response Rate (ORR): response will be evaluated using IMWG 2016 (MM) and Lugano Criteria 2014 (DLBCL). MM disease evaluation will occur 4 weekly and DLBCL imaging evaluation will occur 8 weekly 3. MM: best overall response of stringent complete response (sCR), complete response (CR), very good partial response (VGPR) or partial response (PR); response will be evaluated using IMWG 2016 (MM) - MM disease evaluation will occur 4 weekly 4. DLBCL: best overall response of PR or CR; response will be evaluated using Lugano Criteria 2014 (DLBCL). DLBCL imaging evaluation will occur 8 weekly | — |
Secondary
| Measure | Time frame |
|---|---|
| Current secondary outcome measures as of 12/11/2024: 1. Laboratory parameters, ECGs, and vital signs assessed at designated intervals during each cycle of treatment 2. Extent of exposure to DTP3: relative DTP3 dose intensity (delivered dose versus intended dose) will be calculated for each patient and presented descriptively at the end of a patient's participation in the trial: 2.1. Dose intensity = Delivered dose / Intended dose (expressed as a percentage) 2.2. Delivered dose = cumulative total dose the patient actually received over the duration of the study participation (affected by dose reduction/delay) 2.3. Intended and delivered dose values are calculated at the end of a patient's participation in the trial - after the drug has been permanently withdrawn 3. Pharmacokinetic (PK) parameters of DTP3 will be examined on Day 1, Day 3, and Day 5 of Cycle 1. Derived PK parameters will include: Cmax, Tmax, t1/2, AUC 0-t, AUC 0-‚àû, Vd, Vss 4. Pharmacodynamic (PD) biomarkers of pathway-specific response measured at screening and 24 hours (range 18-36 hours) after the 4th dose (C1W2D2). Tissue collection for PD marker analysis (phospho-JNK and phospho-ERK, cleavedcaspase-3, propidium iodide nuclear staining, propidium iodide nuclear staining ) 4.1 MM: 50 ml of blood and 10ml bone marrow aspirate 4.2 DLBCL: 50ml blood and tumour biopsy (if accesible), 28G core biopsy 5. Efficacy through disease evaluation with CT/FDG PET for MM (IMWG) and DLBCL (lugano criteria). _____ Previous secondary outcome measures: 1. Laboratory parameters, ECGs, and vital signs assessed at designated intervals during each cycle of treatment 2. Extent of exposure to DTP3: relative DTP3 dose intensity (delivered dose versus intended dose) will be calculated for each patient and presented descriptively at the end of a patient's participation in the trial: 2.1.
