About this study

Official title: A Phase I/II Study to Evaluate the Safety, Tolerability, Pharmacokinetic Profile, and Preliminary Efficacy of TSN222 in Subjects With Advanced Solid Tumors or Lymphoma

The study is a first-in-human [FIH], open-label phase 1/2 study of TSN222 in subjects with advanced solid tumors or lymphomas. This study is comprised of a Phase 1 dose escalation and Phase 2 dose expansion component.

Read the detailed description

Phase 1 Part:

Using the standard 3+3 design for dose escalation, the Phase 1 Part will evaluate the prespecified 6 sequential dose levels of 100 microgram (μg), 200 μg, 400 μg, 800 μg, 1600 μg, and 3200 μg of TSN222 as a single agent in subjects with advanced solid tumors or lymphomas.

The eligible subjects will receive TSN222 via i.t. injection on Days 1, 8 and 15 of every 28-day cycle until disease progression or unacceptable toxicity. The dose-limiting toxicity (DLT) observation period will be defined as the first 28 days after the first dose (i.e. the first cycle). Based on the standard "3+3" design, cohorts of 3 to 6 subjects each will be sequentially assigned to the predefined dose levels. Dose escalation will continue until up to the highest planned dose or the MTD or RP2D is determined.

Phase 2 Part:

Phase 2 part will evaluate the efficacy and safety of TSN222 as monotherapy at the preliminary RP2D(s) in 3 cohorts bellow:

Cohort 1: advanced squamous cell carcinoma of head and neck (HNSCC). Cohort 2: advanced melanoma. Cohort 3: advanced other types of solid tumors or lymphomas.

Being tested
Phase I dose escalation, Phase II-HNSCC, Phase II-Advanced melanoma, Phase II-solid tumors or lymphomas
Medical subject headings
Neoplasm Metastasis, Lymphoma

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Phase I-Safety

    A DLT is defined as an adverse event or abnormal laboratory value of Common Terminology Criteria for Adverse Events (CTCAE) grade ≥ 3 assessed as unrelated to disease, disease progression, intercurrent illness, or concomitant medications that occurs within the first cycle of treatment with DYP688. Other clinically significant toxicities may be considered to be DLTs, even if not CTCAE grade 3 or higher.

    AEs as characterized by nature, frequency, and severity according to National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) version 5.0.

    Secondary safety endpoint. The abnormal findings of vital sign, physical examination, laboratory measurements, ECG and ECHO/ MUGA parameters.

    Measured: 28 days

  2. Phase I and phase II-Safety

    AEs as characterized by nature, frequency, and severity according to NCI CTCAE version 5.0.

    Measured: Any AEs (including SAEs) that occurs after first dose through 28 days after receiving the last dose of TSN222

  3. Phase II

    ORR based on investigator assessment using RECIST v 1.1 for solid tumor or Lugano 2014 response criteria for lymphomas.

    Measured: baseline and throughout the study

Secondary outcomes (2)
  1. Phase I/II: PK profile

    Plasma concentrations and PK parameters of TSN222 and its metabolites including but not limited to area under the plasma concentration-time curve (AUC), maximum concentrations (Cmax), trough concentrations (Ctrough).

    Measured: From Cycle 1 to the first day of Cycle 2

  2. Phase I/II: To evaluate the preliminary anti-tumor activity of TSN222

    Based on investigators assessment:

    Overall response rate (ORR). Duration of response (DOR). Time to response (TTR). Disease control rate (DCR). Progression free survival (PFS).

    Measured: Durting the period of patient treatment

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Phase I dose escalation, Phase II-HNSCC and Phase II-Advanced melanoma in people with Has a Pathologically Documented Unresectable Locally Advanced or Metastatic Solid Tumor or Lymphoma, run by Tyligand Bioscience (Shanghai) Limited at 1 site in China.

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 16 inclusion and 29 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: status not confirmed, as of the sponsor's last update on 29 Jul 2024. 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 China. 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 combined 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.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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

Are results available for this study?

Results are not available in the source record.

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

Contact Tyligand Clinical Trial Info (8621-50720081, clinical_trial@tyligand.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Phase I-Safety (time frame: 28 days). 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 29 Jul 2024.
