A Phase II Study to Evaluate Efficacy, Safety and Tolerability of KN026 in Combination With Palbociclib and Fulvestrant in Patients With Locally Advanced HER2-positive Breast Cancer

This is an open-label, multicenter, dose-escalation and parallel-group expansion Phase II clinical trial to evaluate the efficacy, safety and tolerability of KN026 in combination with palbociclib and fulvestrant in women or male with HER2-positive metastatic breast cancer .The subjects will receive 20 mg/kg IV Q2W+ palbociclib 100/125 mg/day orally+/-Fulvestrant 500 mg IM until progressive disease, unacceptable toxicity or death.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Terminated

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

KN026 is an anti-HER2 bispecific antibody that can simultaneously bind two non-overlapping epitopes of HER2, leading to a dual HER2 signal blockade.

Study Type

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

Sampling Method

Non-Probability Sample

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
Dose limiting toxicity (DLT)
Time Frame: up to 24 weeks
The proportion of patients experiencing dose limiting toxicities
up to 24 weeks
Objective response rate (ORR)
Time Frame: through study completion, an average of 1 year
ORR as assessed by the investigator according to RECIST 1.1
through study completion, an average of 1 year

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.
Outcome Measure
Measure Description
Time Frame
Progression free survival (PFS) rates
Time Frame: 6 months and 12 months
Progression free survival (PFS) rates
6 months and 12 months
Clinical benefit rate (CBR)
Time Frame: CBR calculated as the proportion of subjects with best overall response of CR, PR, or SD ≥24 weeks
Clinical benefit rate
CBR calculated as the proportion of subjects with best overall response of CR, PR, or SD ≥24 weeks
Overall survival (OS)
Time Frame: 6 months and 12 months

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
