Summary

This is a Phase 1, open-label, multicenter, dose-escalation/dose-expansion study of YBL-006, in participants with Advanced Solid Tumors. This multicenter study will be conducted in approximately 11-14 participants in the dose escalation phase, and approximately 39-76 participants in dose expansion phase.

Description

Study will consist of three periods:

  1. Screening (up to 28 days)
  2. Treatment (28-day, 14-day, or 21-day cycles)
  3. Follow-up (up to 3 months) The treatment period will consist of 28-day cycles for the dose escalation phase, and 14-day (Cohorts B1, B2 reserve, and B3) or 21-day (Cohort B2) cycles for the dose expansion phase. Each cycle is comprised of two doses of IP administered as an IV infusion on Days 1 and 15 (dose escalation phase) or one dose of IP administered as an IV infusion on Day 1 (dose expansion phase). The treatment duration will be of 1 year in patients who are responding to the treatment.

Dose Escalation:

An accelerated titration design will be utilized for the lowest dose cohort (0.5 mg/kg) in the dose escalation part. Whereas the traditional 3 + 3 design will be utilized for the higher dose cohorts until the proposed starting dose for the Expansion Cohort is determined

Expansion Cohorts:

Up to four tumor-specific expansion cohorts consisting of approximately 39 to 76 participants will evaluate the safety, efficacy, PK, and PD of YBL-006 at the proposed doses of YBL-006"

Eligibility

Yes No Not Sure

Inclusion Criteria

Written consent on an IRB/ IEC-approved ICF prior to any study-specific evaluation
Male or female aged 18 years (or age of legal adult, whichever is older)
Life expectancy of at least 3 months
ECOG performance status of 0 to 1
Availability of archival tumour tissue and consent to provide archival tumour for retrospective biomarker analysis, or consent to undergo a fresh tumour biopsy during screening. Participants who do not have an existing (archived) tumour specimen and are unwilling to undergo a biopsy may be enrolled with prior approval from the Sponsor
For participants in dose escalation only: Histologically confirmed solid tumours (except primary CNS tumours) that are unresectable, locally advanced, or metastatic and have progressed following all standard treatments or is not appropriate for standard treatments
Must have at least one measurable lesion based on RECIST Version 1.1. A previously irradiated lesion can be considered a target lesion if the lesion is well defined, measurable and there is objective evidence of interval increase in size
CNS metastasis must be without evidence of progressive neurological symptoms or requires increasing doses of corticosteroids to control the CNS disease for at least 4 weeks. If a participant requires corticosteroids for management of CNS disease, the dose must have been stable with low-dose (same or less than 10 mg/day prednisone or equivalent) for at least two weeks preceding C1D1
Immunosuppressive doses of systemic medications, such as steroids (doses > 10 mg/day prednisone or equivalent) must be discontinued at least 2 weeks before IP administration
Prior surgery that required general anaesthesia must be completed at least 14 days before IP administration. Surgery requiring local/epidural anaesthesia must be completed at least 72 hours before IP administration and participants should be recovered

values
Neutrophils 1000/L Platelets 75,000/L Haemoglobin 9.0 g/dL (may have been
transfused) Creatinine 1.5upper limit of normal (ULN) Aspartate

aminotransferase (ALT) 2.5ULN (Except with liver metastasis, AST 5ULN)
Bilirubin 1.5ULN (except participants with Gilbert's syndrome, who must have
total bilirubin < 3.0 mg/dL)
\. Women must meet 1 of the following criteria: postmenopausal for at least
consecutive months; surgically incapable of bearing children (i.e., have
had a hysterectomy or bilateral oophorectomy); or utilizing a reliable form of
contraception. In general, the decision for appropriate methods to prevent
pregnancy should be determined via discussions between the Investigator and
the study participant. WOCBP must agree to use a reliable form of
contraceptive during the study Treatment Period and for at least 120 days
following the last dose of IP
\. Men must agree to the use of acceptable contraceptive use and avoid sperm
donation, during the study Treatment Period and for at least 180 days after
the last dose of IP
\. For the Expansion Cohort, participants enrolling must also meet the
following inclusion criteria
Confirmed diagnosis of one of the following tumour types
For all Expansion Cohorts (B1, B2, B2 reserve, and B3), histologically confirmed advanced solid tumours (except primary CNS tumours) that are unresectable, locally advanced, or metastatic and have progressed following all standard treatments, or are not appropriate for standard treatments
For the B3 cohort, participants must meet one of the following
Participants must have progressed following at least one line of standard systemic therapy and there must not be other approved/standard therapy available that has been shown to prolong overall survival (i.e., in a randomized trial against another standard treatment or by comparison to historical controls); participants who cannot receive other standard therapy that has been shown to prolonged survival due to medical issues will be eligible, if other eligibility criteria are met; OR
Participants for whom no standard treatment exists that has been shown to prolong overall survival
The following tumour types are eligible for the B3 cohort
Metastatic NSCLC: Histologically or cytologically confirmed diagnosis of stage IV NSCLC (cases of non-squamous cell carcinoma or NSCLC of unknown subtype) with high ( 50%) PD-L1 tumour expression as determined by IHC, without EGFR sensitizing (activating) mutation by PCR and anaplastic lymphoma kinase (ALK) translocation as determined by IHC or fluorescence in situ hybridization (FISH). For pathologically confirmed squamous cell carcinoma, only high ( 50%) PD-L1 tumour expression is required
