Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Doctors leading this study would like to learn about providing cancer treatment/therapies to Nigerian women with breast cancer based on their human epidermal growth factor receptor 2 (HER2) status. This study will focus on the efficacy and safety of anti-HER2 cancer treatment before and after surgery.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Doctors leading this study would like to learn about providing cancer treatment/therapies to Nigerian women with breast cancer based on their human epidermal growth factor receptor 2 (HER2) status. This study will focus on the efficacy and safety of anti-HER2 cancer treatment before and after surgery. Participants with HER2-positive breast cancer will receive a combination of trastuzumab with pertuzumab (PHESGO) plus chemotherapy.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Phase 1: All Participants

All participants will receive a combination of:

* docetaxel (starting dose - 75 mg/m2), increasing to 100mg/m2 by cycle 2 (if tolerated) for 4-6 cycles (for a total of 18 weeks). Docetaxel will be give as an injection.
* trastuzumab and pertuzumab (loading dose of 1200 mg of pertuzumab and 600 mg trastuzumab) for 52 weeks followed by 600 mg pertuzumab and 600 mg trastuzumab every 3 weeks for 15 cycles (for a total of 52 weeks). These two drugs will be given as subcutaneous injections under the skin.

Group Type EXPERIMENTAL

Trastuzumab emtansine

Intervention Type DRUG

A chemotherapy drug.

Pertuzumab Injection

Intervention Type DRUG

A prescription medicine that is approved for use in combination with trastuzumab and docetaxel in people who have HER2-positive breast cancer that has spread to different parts of the body (metastatic) and who have not received anti-HER2 therapy or chemotherapy for metastatic breast cancer.

Docetaxel

Intervention Type DRUG

A chemotherapy drug.

Phase 2 - Operable (participants who are able to have surgery)

Participants in this group will have breast cancer that shows a complete or incomplete response (as assessed by ultrasound) to the study drug combination given in phase 1 of study. Based on how their breast cancer responds to the phase 1 study drugs, participants in this group will:

\- undergo surgery and will continue to receive pertuzumab (600 mg) and trastuzumab (600 mg) for 36 weeks. Participants may also receive hormone therapy (as recommended by study doctor) based on status of breast cancer. This drug will be given as an injection under the skin.

Some participants in this group may also receive tamoxifen (as an oral tablet; 20 mg daily for 10 years after surgery), letrozole (as an oral tablet 2.5 mg daily for 10 years after surgery) and/or goserelin (hormone injection 10.8 mg every 1-3 months) based on their human epidermal growth factor receptor 2 (HER2) status as assessed by the treating doctor.

Phase 2 - Inoperable (participants who are not able to have surgery)

Participants in this group will have breast cancer that shows a partial response (as assessed by ultrasound) to the study drugs given in phase 1 or their breast cancer stayed the same or got worse after receiving study drugs during phase 1. Based on how their breast cancer responds to the phase 1 study drug regimen, participants in this group will receive trastuzumab emtansine (intravenously) plus standard chemotherapy as recommended by their doctor.
