About this study

Official title: Neoadjuvant Treatment of Ontruzant (SB3) in Patients With HER2-positive Early Breast Cancer: An Open-Label, Multicenter, Phase IV Study

The treatment of patients with HER2 positive early breast cancer has continuously improved over the last decades. Up to now both, trastuzumab and pertuzumab are approved in combination with chemotherapy (CTX) not only for the adjuvant but also for the neoadjuvant treatment of early breast cancer patients. A high pCR rate in the neoadjuvant setting was shown in several trials and observational studies with CTX+ trastuzumab and with CTX+ pertuzumab. The efficacy is dependent on a variety of mechanisms including the blocking of the important PI3K/Akt and MAPK pathways, and ADCC (antibody dependent cellular toxicity).

Recently the biosimilar Ontruzant® (SB3) has been introduced into the treatment of HER2 positive breast cancer as a biosimilar. Efficacy and toxicity have been shown to be equivalent to the first approved antibody, however, data from the real-world setting have not been published like it has for the originally approved antibody. Therefore, the aim of this study is to establish safety and efficacy for Ontruzant® in the real world setting. Patients can be included if they are treated with Ontruzant® in the neoadjuvant setting. Additionally, the study will be accompanied by a comprehensive immune monitoring program and biomarker program to explore immune oncology potential for the neoadjuvant treatment.

Ontruzant + Pertuzumab (optional) + ChemotherapyExperimentalAll patients will receive 6 cycles of Ontruzant® i.v. q21d in combination with standard chemotherapy with or without pertuzumab, at the discretion of investigator's decision. Initial dose of Ontruzant® i.v. will be 8 mg/kg b.w. followed by 5 cycles of Ontruzant® i.v. 6 mg/kg b.w. q21d. Clinical and bioptic tumor assessment will be performed during baseline and during surgery. Study treatment will be applied until state of the art surgery, onset of unacceptable toxicities, progression or withdrawal of consent. A safety follow-up is planned for 30 days after the last administration of study medication.
Receives: Drug: Ontruzant; Drug: Chemotherapy; Drug: Pertuzumab

What is being measured

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

  1. Pathological complete response (pCR) rate

    Pathological complete response (pCR) rate, defined as the complete absence of tumor cells (ypT0; ypN0) after neoadjuvant study treatment of HER2-positive early breast cancer patients treated with Ontruzant® (SB3) in combination with pertuzumab (optional) and a standard chemotherapy.

    Measured: Pathological complete response will be assessed at final surgery.

Secondary outcomes (4)
  1. Pathological complete response (pCR) rate in patients without pertuzumab

    Pathological complete response (pCR) rate, defined as the complete absence of tumor cells (ypT0; ypN0) after neoadjuvant study treatment of HER2-positive early breast cancer patients treated with Ontruzant® (SB3) and a standard chemotherapy who were not treated with pertuzumab.

    Measured: Pathological complete response will be assessed at final surgery.

  2. Number of participants wuth treatment-related adverse events as assessed by CTCAE v5.0

    The safety endpoints for the study will include rate of AE/SAEs and fatal SAEs, causality and outcome of AE/SAEs, rate of treatment discontinuations and reasons, Changes in vital signs, laboratory values etc. Grading of AE/SAEs will be based on NCI CTCAE v5.0.

    Measured: Adverse ebents will be assessed from first administration of trial treatment until 30 days after last administration of trial treatment.

  3. EORTC-QLQ-C30

    To evaluate changes in health related quality of life (QoL) assessments from baseline in all subjects using Quality of Life Questionnaire Core 30 (EORTC QLQ-C30).

    Measured: Every nine weeks from first administration of trial medication through study completion, up to 30 days after administration of last medication.

  4. EORTC-QLQ-BR23

    To evaluate changes in health related quality of life (QoL) assessments from baseline in all subjects using Quality of Life Questionnaire Breast Cancer-Specific Quality of Life (EORTC QLQ-BR23).

    Measured: Every nine weeks from first administration of trial medication through study completion, up to 30 days after administration of last medication.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Ontruzant, Chemotherapy and Pertuzumab in people with Breast Cancer and Breast Neoplasms, run by Institut fuer Frauengesundheit at 11 sites in Germany.

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 11 inclusion and 14 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 18 Apr 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 11 sites in Germany. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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 NeoON Study Manager (+49 9131 9279136, neo.on@ifg-erlangen.de), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Pathological complete response (pCR) rate (time frame: Pathological complete response will be assessed at final surgery.). 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 18 Apr 2023; AzTrials last refreshed its copy on 7 Nov 2026.
