About this study

Mesenchymal epithelial transition factor (c-MET) is a receptor tyrosine kinase that, when engaged by its ligand hepatocyte growth factor (HGF), has been implicated in various cellular process including development as well as oncogenesis.

SAIT301 is a novel humanized monoclonal antibody targeting the alpha chain of extracellular domain of c-MET. Binding of SAIT301 to c-MET blocks HGF binding and inhibits HGF-mediated signaling. Furthermore, SAIT301 also induces efficient c-MET internalization from the cell surface and subsequent degradation, resulting in inhibition of growth of the c-MET addicted cancer cells.

The sponsor decided to enroll subjects with tumors that express c-MET (by immunohistochemistry [IHC]) for this study, as the subjects with no c-MET expression are unlikely to benefit from SAIT301 treatment.

Stage 1 of this Phase I study is designed to evaluate the safety, tolerability, pharmacokinetic (PK) profile, and anti-tumor activity of SAIT301 administered as a single IV infusion in 21 day cycles, for up to 4 cycles. Subjects without evidence of tumor progression after 4 cycles will be eligible to continue on SAIT301 treatment if there is no evidence of tumor progression for a further 4 cycles (Cycles 5 to 8). Biomarkers related to SAIT301 and/or tumor response will also be evaluated.Stage 2 will further evaluate the safety and PK profile of SAIT301 in select types of cancers. Dosing frequency may be adjusted based on the PK profile obtained during Stage 1.

Read the detailed description

The primary objectives of the study are as follows:

  • To evaluate the safety and tolerability of SAIT301.
  • To determine the MTD of SAIT301 and the dose level of SAIT301 where dose limiting toxicity (DLT) is observed in subjects with advanced solid tumors or define recommended Phase II dose (RP2D) as an alternative to establishing the MTD.

Methodology: This first in man study will consist of 2 stages. Stage 1 will be a dose escalation study with a 3 + 3 design and will evaluate the safety, tolerability, PK profile, biomarkers, and preliminary anti-tumor activity of ascending doses of SAIT301 in subjects with c-MET + advanced solid tumors and define the MTD (or recommended Phase II dose [RP2D]) of SAIT301. If the PK trough levels exceed the minimum acceptable trough level for SAIT301 (25 μg/mL), the Safety Review Committee (SRC) may elect to terminate further dose escalation and declare a recommended Phase II dose (RP2D) and schedule as an alternative to establishing the MTD. In Stage 2 the MTD (or RP2D) defined in Stage 1 will be administered to additional subjects with selected diagnoses, 15 subjects per selected diagnosis, to further evaluate the safety and PK profile, and any evidence of anti tumor activity of SAIT301 in these populations. The tumor types to be included in Stage 2 will be defined in a protocol amendment at a time close to study execution based on information available at that time.

The treatment period will consist of 21-day cycles. On Day 1 of each cycle, SAIT301 will be administered as an intravenous (IV) infusion.

For dose level 1, the first subject will receive an IV infusion of SAIT301 on Cycle 1 Day 1 and will be followed for 21 days (Cycle 1).

If the first subject at dose level 1 experiences a DLT during Cycle 1, 1 additional subject will be enrolled and will receive dose level 1, which is 50% of dose level 1. If this subject at dose level -1 does not experience a DLT during Cycle 1, 2 more subjects will be enrolled at dose level -1.

If the first subject at dose level 1 does not experience a DLT during Cycle 1, the second and third subjects will receive SAIT301 at dose level 1 and will be followed for 21 days (Cycle 1). At the discretion of the SRC, if the first 3 subjects at dose level 1 do not experience a DLT during Cycle 1, dose level 2 may be administered in the next cohort. If one of these subjects experiences a DLT, the cohort will be expanded and evaluated as described below.

For dose level 2 and each subsequent dose level, 3 subjects will receive SAIT301 on Day 1 of Cycle 1 and will be followed for 21 days (Cycle 1). If none of the 3 subjects experience a DLT, the next dose level can be administered in the next cohort. If 1 or more of the first 3 subjects experience a DLT, 3 more subjects will receive the same dose level. Dose escalation will continue until at least 2 subjects in a cohort of 3 to 6 subjects experience a DLT (i.e., ≥33% of subjects with a DLT at that dose level). Considering the possibility of relatively low efficacy, each subjects of dose level 1 and 2 can be administered with higher dose level after their first administration. This individual dose escalation can be determined by Investigators when safety data of the higher dose level are available.

For both Stage 1 and 2, subjects will continue to receive the assigned dose level of SAIT301 until unacceptable toxicity, documented progression of disease, another criterion for discontinuation is met, or until 4 cycles have been completed.

Subjects without evidence of tumor progression after 4 cycles may continue on SAIT301 treatment if there is no evidence of tumor progression for a further 4 cycles (Cycles 5 to 8). Subjects without evidence of tumor progression at the completion of Cycle 8 will be eligible for a follow-on protocol.

Subjects who experience a DLT will be discontinued from further treatment. At the completion of the dose escalation stage, the SRC may for Stage 2 alter the dosing interval between cycles based on emerging PK data from lower SAIT301 dose levels.

SAIT301ExperimentalFor Stage 1, subjects will be sequentially assigned to 1 of approximately 8 cohorts comprised of 3 to 6 subjects each. SAIT301 will be administered according to a modified Fibonacci sequence and following a 3 + 3 design. For Stage 2, the MTD or (RP2D) determined in the Stage 1 will be administered to additional subjects with selected diagnoses, 15 subjects per selected diagnosis. After completion of Stage 1 the SRC may elect to increase the interval between doses (i.e., increase cycle length to 28 days) based on the emerging PK data from the lower SAIT301 dose levels.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing SAIT301 in people with Solid Tumors, run by Young Suk Park at 1 site in South Korea.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 15 inclusion and 11 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 17 Jan 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in South Korea. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Incidence of treatment-emergent adverse events (TEAEs), serious adverse events (SAEs), adverse events (AEs) of at least Common Terminology Criteria for Adverse Events (CTCAE) Grade 3 severity, and discontinuations due to AEs. (time frame: Up to 25 weeks for each subject). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 17 Jan 2018.
