About this trial

This study aims to provide a basis for further clinical development of YK012.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Written informed consent obtained from the patient prior to performing any study-related procedures, including screening visits.

Males or females aged ≥ 18 to ≤ 65 years.

Participants with an Eastern Cooperative Oncology Group (ECOG) performance score of ≤ 1.

Participants with an estimated survival time of more than 12 weeks.

Disqualifiers

History of malignancy other than B-cell NHL within 5 years prior to study entry, except for local cancers that have been clearly cured or have been free of disease for at least 5 consecutive years.

Participants with clinically symptomatic metastases to the central nervous system or meninges, or other evidence of uncontrolled metastases to the CNS or meninges, judged by the Investigator.

a) History of or current relevant CNS pathology as epilepsy, seizure, paresis, aphasia, apoplexia, severe brain injuries, cerebellar disease, organic brain syndrome, psychosis; b) Evidence for presence of inflammatory lesions and/or vasculitis on cerebral MRI.

Trial outcomes

Primary outcomes

1

Incidence of subjects with adverse events (AEs) and/or serious adverse events (SAEs)

An AE is defined as any untoward medical event that occurs after a subject receives the investigational drug, which may be manifested as symptoms, signs, diseases, or laboratory abnormalities, but may not necessarily have a causal relationship with the investigational drug. An SAE refers to an untoward medical occurrence such as death, life-threatening event, permanent or serious disability or loss of function, need for hospitalization or prolongation of hospitalization after the subject receives the investigational drug, and congenital abnormalities or birth defects.

Time frame
From the first infusion of YK012 until 28 Days after end of treatment
2

The incidence and profile of dose-limiting toxicity (DLT)

The toxicities occurring within 28 days (i.e., DLT observation period) after the first dose will be defined as DLTs in the discretion of the investigator as possibly, probably, or definitely related to the IMP (Investigational Medicinal Product).

Time frame
28 days after the first dose
3

The maximum tolerated dose and/or the recommended dose for further clinical trial

The MTD will be determined based on the occurrence rate of the DLT. The MTD is defined as the highest dose in which 1/6 or less subjects experience a DLT.

Time frame
28 days after the first dose

Secondary outcomes

1

Area under the concentration-time curve (AUC) after administration

Assess the AUC after treatment with YK012

Time frame
12 weeks
2

Maximum concentration (Cmax) after administration

Assess the Cmax after treatment with YK012

Time frame
12 weeks
3

Time to maximum concentration (Tmax) after administration

Assess the Tmax after treatment with YK012

Time frame
12 weeks
4

Terminal elimination half-life (T1/2) after administration

Assess the terminal elimination half-life (T1/2) after treatment with YK012

Time frame
12 weeks
