This is a phase I, multi-center, open-label, dose escalation study to evaluate the safety, tolerability, pharmacokinetics and clinical activity of LP-118 in patients with advanced malignancies, including solid tumors and lymphomas. LP-118 is a BCL-2/BCL-XL small molecule inhibitor.
LP-118 is an oral selective BCL-2 inhibitor with tuned BCL-XL activity, aiming to improve antitumor efficacy and reduce the risk of thrombocytopenia. Clinical development of LP-118 includes targeting of relapsed or refractory hematological malignancies and solid tumors. This is a multi-center, open-label, Phase 1 dose escalation study of LP-118 in patients with advanced malignancies, including advanced/metastatic solid tumors and relapsed/refractory B cell, T/NK cell lymphomas, to determine the safety, tolerability, pharmacokinetics profile and preliminary anti-tumor efficacy. Upon completion of the Phase 1 dose escalation study and establishment of maximum tolerated dose (MTD) and recommended phase 2 dose (RP2D), the dose expansion study will be implemented in patients with protocol designated type of disease.

Maximum tolerated dose (MTD)
The highest dose that does not cause unacceptable side effects or overt toxicities which will be assessed by NCI CTCAE v5.0.
Time frame: Up to 24 months
Adverse events
The incidence and severity of adverse events as assessed by NCI CTCAE v5.0.
Time frame: Up to 24 months
Recommended phase II dose (RP2D)
The safe dose that demonstrates the greatest pharmacological activity.
Time frame: Up to 24 months
PK evaluation of area under the plasma concentration versus time curve (AUC) of LP-118
AUC indicates the extent of exposure to LP-118 and its clearance rate from the body.
Time frame: Up to Cycle 6 (each cycle is 28 days)
PK evaluation of peak plasma concentration (Cmax) of LP-118
Cmax indicates the highest drug concentration in the blood after LP-118 administration.
Time frame: Up to Cycle 6 (each cycle is 28 days)
PK evaluation of time to maximum concentration (Tmax) of LP-118
Tmax indicates the time taken to reach the maximum drug concentration (i.e. Cmax).
Time frame: Up to Cycle 6 (each cycle is 28 days)
Overall response rate (ORR)
The proportion of patients who have a partial or complete response after LP-118 treatment.
Time frame: Up to 24 months

Time frame: Up to 24 months
Progression-free survival (PFS)
The time from first dose to disease progression or death, whichever occurs first.
Time frame: Up to 24 months
