What is Ibrance
PalbociclibThe Generic name of this drug
Treatment SummaryPalbociclib is a medication that works by affecting the cell cycle machinery. It is a type of cyclin-dependent kinase inhibitor that was developed by Pfizer Inc to treat certain types of breast cancer. Palbociclib was originally approved by the FDA in March 2015 for the treatment of HR-positive, HER2-negative advanced or metastatic breast cancer in women. The indications for Palbociclib were then expanded in 2019 to also include male patients based on evidence from clinical studies.

Effectiveness
How Ibrance Affects PatientsPalbociclib works by blocking cell growth and DNA replication in certain cancer cells, making them unable to reproduce and grow. This stops the cells from moving into the next stage of the cell cycle, which leads to them not being able to divide and reproduce. Studies on breast cancer cells have found that this drug is more effective in cells with high levels of a certain protein called RB1, low levels of a protein called CDKN2A, and medium levels of a protein called CCND1. In clinical trials, when taken with letrozole, palbociclib was able to increase the length of time without cancer
How Ibrance works in the bodyPalbociclib is a drug that stops cancer cells from reproducing. It works by binding to an enzyme called CDK4/6, which controls the transition of cells from the G1 phase to the S phase. Palbociclib prevents this transition, thus halting the growth of cancer cells. It also stops the phosphorylation of proteins like retinoblastoma, which are involved in cell cycle progression. Palbociclib is effective against CDK4/6, but not other types of enzymes.

Ibrance Reviews: What are patients saying about Ibrance?
5Patient Review
11/1/2016 Ibrance has been working well for me so far. My tumor has shrunk a little bit, and I'm hopeful that it will continue to do so. I've had some stomach issues and fatigue, but overall I feel great.
5Patient Review
6/26/2018 I was diagnosed in 2015 and metastasized to both bottom vertebrae. I started on Ibrance with letrozole. I had a little joint problem in my fingers however Dr. said it was side effect of the Letrozole not the Ibrance.No side effects from Ibrance to speak of. Pet scans every six months, all have been clear. Next one up is July 18th..Dr. calls me a rockstar and I am so thankful for this drug!!!! God Bless Everyone!!!
5Patient Review
8/7/2020 Letrozole/Ibrance has been a godsend. After just one day of treatment, the pain in my lower back from metastasis lessened significantly. I've now had seven cycles with no progression of bone destruction according to two scans. The only drawbacks have been loose stools and hair thinning, but these are minor compared to the relief I've experienced.
5Patient Review
11/29/2020 I was diagnosed with stage 4 breast cancer that had spread to my lungs, spine, and ribs. I started treatment with Ibrance and Letrazole. The side effects were manageable (hair loss) but after 7 months my blood counts were low so I switched to a lower dose of Ibrance. After 8 months my cancer markers have gone from 117 to 65 and I feel good overall.
5Patient Review
3/16/2019 Ibrance has been great for me, except for the fatigue and itchy scalp. But those are manageable side effects considering the benefits I've seen.

These questions and answers are submitted by anonymous patients, and have not been verified by our internal team.What is the life expectancy on Ibrance?
"The median overall survival for women treated with Ibrance and Faslodex was 34.9 months, while the median overall survival for women treated with Faslodex alone was 28.0 months."
Answered by AI
What does Ibrance do to the body?
"IBRANCE interfere with the activity of the proteins CDK4 and CDK6, which are necessary for both healthy and cancer cells to divide. Hormonal therapy blocks or reduces the binding of hormones with hormone receptors to prevent the cells from growing and dividing."
Answered by AI
Is Ibrance like chemo?
"Bottom Line: Ibrance is not a traditional form of chemotherapy. It is an oral medication known as a targeted therapy, and is in the class of drugs known as CDK 4/6 inhibitors. It helps to slow cell growth in both cancer cells and healthy cells."
Answered by AI
What type of cancer does Ibrance treat?
"Ibrance is a cancer medication that works by inhibiting certain enzymes in the body. It is used in combination with an aromatase inhibitor, a type of hormonal therapy, to treat hormone-receptor-positive, HER2-negative breast cancer that has not been treated with hormonal therapy before. This medication is for use in postmenopausal women or men."
