About

PROTEOZ is a proteasome inhibitor, an antineoplastic agent used in the treatment of certain hematologic malignancies. It works by reversibly inhibiting the chymotrypsin-like activity of the 26S proteasome, a large protein complex responsible for degrading ubiquitinated proteins. This inhibition disrupts multiple intracellular signaling pathways, leading to the accumulation of misfolded or ubiquitinated proteins within the cell. This accumulation triggers endoplasmic reticulum stress, activates pro-apoptotic pathways, and ultimately induces programmed cell death (apoptosis) in cancer cells. The proteasome plays a critical role in cell cycle progression, gene expression, and protein homeostasis, making its inhibition a potent strategy against rapidly dividing cancer cells.

Its targeted mechanism of action makes it particularly effective in conditions like multiple myeloma and mantle cell lymphoma, where proteasome activity is often dysregulated. By interfering with the degradation of regulatory proteins, PROTEOZ can sensitize cancer cells to other treatments and overcome resistance mechanisms. It is typically administered as part of a combination regimen, enhancing its overall therapeutic impact and improving patient outcomes in these challenging cancers.

Safety Measures

Alcohol - Avoid alcohol as it may exacerbate peripheral neuropathy or liver toxicity.
Pregnancy - Contraindicated in pregnancy due to potential for fetal harm. Effective contraception is required for both male and female patients.
Breastfeeding - Breastfeeding is not recommended during treatment and for a period after the last dose due to potential harm to the infant.
Liver - Use with caution in patients with moderate to severe hepatic impairment; dose adjustments are necessary. Monitor liver function closely.
Kidney - No specific dose adjustment required for renal impairment, but monitor overall patient condition.
Lung - Monitor for pulmonary adverse reactions, including acute respiratory distress syndrome and interstitial pneumonia.
