A phase 1 dose escalation and expanded cohort study of TR115 in the treatment of adult patients with relapsed/refractory non-hodgkin's lymphoma or advanced solid tumors.

This is a open-label, dose escalation and expansion, accelerated titration combined 3+3 design, phase 1 study, to evaluate the safety and tolerability, and to determine the Recommeded Phase II Dose (RP2D) of TR115 when administered bid in patients with non-hodgkin's lymphoma or advanced solid tumors. During the dose escalation phase, Up to 6 cohorts of 1-6 0r 3-6 patients each will be treated in the study.

Patients will receive study treatment until criteria for study termination are met. A safety Follow-up Visit will conducted 30 days (±7 days) after the last dose of treatment. Patients who discontinue study treatment for reasons other than disease progression will have post-treatment follow-up for disease assessment until start of new anticancer treatment, lost to follow-up, death, or until the sponsor stops the study, whichever comes first.

After finishing the dose escalation phase, a dose extension phase will be initiated with additional patients included in order to further evaluate the tolerability, pharmacokinetics, and efficacy at the recommended dose that have been evaluated in the dose escalation phase.

Adverse events will be assessed using the NCI Common Terminology Criteria for Adverse Events (NCI-CTCAE) Version 5.0.

Tumor response will be assessed by computed tomography (CT) and/or magnetic resonance imaging (MRI) scan using Lugano 2014/RECIST 1.1 criteria, assessed by the investigator.
