A Study of Q-1802 in Patients With Advanced Solid Tumors

July 24, 2023 updated by: QureBio Ltd.

A Phase I Clinical Trial to Evaluate the Safety, Tolerability and Efficacy of Q-1802 in Patients With Advanced Solid Tumors

Q-1802 is a bispecific antibody targeting both the tumor-specific antigen Claudin 18.2 and the immune checkpoint PD-L1. This is a multi-center, single-arm, open-label design to evaluate the safety and tolerance of Q-1802 in patients with advanced solid tumors, together with an assessment of pharmacokinetic characteristics and efficacy. The study consisted of two compartments: the dose-exploration stage and the dose-extension stage.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 75 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Male or female, age ≥18 years and ≤75 years.
  • Patients with at least one measurable lesion per RECIST (v1.1) (applicable to the dose-extension stage).
  • Eastern Cooperative Oncology Group (ECOG) performance status score 0 or 1 at screening and no deterioration occurs within two weeks before enrollment.
  • Life expectancy period ≥ 12 weeks.
  • Patients who have sufficient baseline organ function and whose laboratory data meet the following criteria (receiving no treatment of blood transfusions, albumin, recombinant human thrombopoietin, or colony-stimulating factor within 14 days before the first dose of this study).
  • Patients with advanced gastric mucinous adenocarcinoma, advanced ovarian mucinous carcinoma or other dominant tumors participating in the dose-extension stage must provide eligible tumor tissue samples for biomarker detection; if subjects agree, tumor tissue samples should also be provided during the dose-exploration stage.

Exclusion Criteria:

  • Patients who have received any prior PD-1/PD-L1 antibody therapy (applicable to the dose-exploration stage).
  • Patients with uncontrolled blood pressure (systolic blood pressure ≥ 150 mm Hg and/or diastolic blood pressure ≥ 100 mm Hg) or previous hypertensive crisis or hypertensive encephalopathy.
  • Patients with active peptic ulcer, gastric outlet obstruction or persistent recurrent vomiting.
  • Patients with a history of monoclonal antibody allergic reaction.
  • Patients who are considered ineligible by the investigator due to any other severe, acute or chronic disease or other causes that the investigator considers could affect the patient's participation or assessment in the study.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description

Time Frame: 28 days
Incidence of dose limiting toxicities(DLTs). A DLT is defined as an adverse event or abnormal laboratory value assessed as unrelated to disease, disease progression, inter-current illness, or concomitant medications that occurs within the first treatment cycle with Q-1802.
28 days

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.

70 days
Progression-free survival (PFS)
