What is Ibrance (palbociclib) for?
Palbociclib is indicated for the treatment of postmenopausal women with estrogen receptor (ER)-positive, human epidermal growth factor receptor 2 (HER2)-negative advanced breast cancer as initial endocrine-based therapy for their metastatic disease. It is indicated in combination with an aromatase inhibitor (an hormonal therapy) as initial endocrine based therapy in postmenopausal women or fulvestrant in women with disease progression following endocrine therapy.
How does Ibrance (palbociclib) work?
Palbociclib is an inhibitor of cyclin-dependent kinase (CDK) 4 and 6.
Before a cell can divide, it has to go through four phases. The first phase is a growth phase (G1-phase), the second a synthesis phase (S-phase), the third another growth phase (G2-phase) and the last phase, where the cell divides (M-phase). Cancer cells divide exceedingly fast, passing through these 4 phases rapidly. Palbociclib blocks the progression from the first G1-phase, into the second S-phase. It does this by inhibiting the cyclin-dependent kinases 4 and 6 (CDK4 and CDK6)—two proteins that are involved in entering the S-phase[1].

Samantha Reynolds –
Ibrance has been a lifeline in my ongoing battle with metastatic breast cancer. After exhausting various treatment options, I was hesitant to place my hope in yet another medication. However, Ibrance has exceeded my expectations. Its targeted approach to blocking cancer cell growth has provided me with a newfound sense of stability. While I have experienced some side effects such as fatigue and nausea, they are manageable compared to the relentless onslaught of symptoms from previous treatments. Ibrance has not only halted the progression of my cancer but has also allowed me to reclaim some semblance of normalcy in my life. It’s more than just a pill; it’s a symbol of resilience and perseverance. I am profoundly grateful to the researchers and developers behind Ibrance for giving me the opportunity to continue my fight with hope and determination.
