Trial overview

Official title: A multicenter, open-label Phase I/II trial of the safety and efficacy of the dHER2 recombinant protein combined with immunological adjuvant AS15 in patients with metastatic breast cancer overexpressing HER2/neu
Trial description: Patients will receive a maximum of 18 injections of dHER2 vaccine in a treatment schedule that will last for up to about a year, and thereafter there will be a follow-up period of about one more year.
Primary purpose:
Prevention
Trial design:
Single Group Assignment
Masking:
None (Open Label)
Allocation:
Non-randomized
Primary outcomes:

Vaccine-related Grade 3 or 4 toxicity (other than skin toxicity and influenza-like symptoms) according to the Common Terminology Criteria for Adverse Events version 3.0

Timeframe: During the study.

Objective clinical response (CR or PR)

Timeframe: At each tumor evaluation (Visits 7, 14 and 21)

Secondary outcomes:

Stable disease

Timeframe: At each tumor evaluation (Visits 7, 14 and 21)

Mixed response

Timeframe: At each tumor evaluation (Visits 7, 14 and 21)

Time to disease progression

Timeframe: At the time of analysis.

Time to onset of response, defined as time from first vaccination to the initial response

Timeframe: At the time of analysis.

The duration of overall response is measured from the time that measurement criteria are met for complete response or partial response until the first date that recurrent or progressive disease is objectively documented

Timeframe: At the time of analysis.

Anti-dHER2, anti-HER2 ECD and anti-HER2 ICD seropositivity.

Timeframe: At all point during treatment (as specified in the study schedule)

Functional activity in vitro

Timeframe: At all point during treatment (as specified in the study schedule)

Frequency of cellular immune response in vitro to dHER2, HER2 ECD and HER2 ICD

Timeframe: At all point during treatment (as specified in the study schedule)

Adverse events of Grades 3 and 4

Timeframe: Throughout the study

Adverse events related to potential cardiotoxicity

Timeframe: Throughout the study

Solicited local and general signs and symptoms (recorded by the patients on diary cards)

Timeframe: During a period of four days following each administration of study vaccine

Unsolicited adverse events (serious and non-serious)

Timeframe: At any time during the study

Unsolicited serious adverse events

Timeframe: At any time during the study

Any documented toxicity

Timeframe: At any time during the study

Left ventricular ejection fraction

Timeframe: At screening and at appropriate intervals during treatment.

Laboratory values: hematological and biochemical variables (including coagulation).

Timeframe: at all point during treatment as specified in the study schedule

Vital signs.

Timeframe: at each administration

Electrocardiographic results

Timeframe: at the end of cycle 1 and cycle 2 and at first follow-up visit

Results of physical examination

Timeframe: At each visit
