Our New Therapies and the Development of Cross Resistance to these Drugs

Men with metastatic castrate resistant prostate cancer (mCRPC) have become fortunate over the last few years as there we now have a number of new drugs available which can extend our life and can also have some palliative effects. However, as we have more treatments being approved, we find that we are faced with a significant issue, how to sequence these drugs. The major problem causing this sequencing crisis is cross-resistance. The use of each of any of these drugs limits the use of the another drug in men who have failed the original prior therapy. This problem, cross-resistance, is [...]

Evaluating The Side Effects Of Docetaxel (Taxotere) vs Cabazitaxel (Jevtana)

Many men express great hesitation to move to chemotherapy with both docetaxel (taxotere) and cabazitaxel (Jevtana) because of the side effects which can include alopecia (hair loss), nail changes, neuropathy, and dysgeusia (a distortion of the sense of taste). A group of researchers hypothesized that the adverse side effects (AE) of these two chemotherapy drugs, cabazitaxel and docetaxel would be different. To compare the AEs they prospectively collected data on treatment side effects reported from the clinical trial databases of docetaxel every 3 weeks (q3w) (in TAX327 and VENICE) and cabazitaxel q3w (in TROPIC). They found that the frequency of [...]

Is Cabazitaxel Before Docetaxel The Future Way To Go? *

Chemotherapy for prostate cancer is still limited to just two drugs, docetaxel (Taxotere) and cabazitaxel (Jevtana). Both of these chemotherapy drugs are taxanes, but they seem to be very different in their mode of action. A study published online in Clinical Cancer Research, indicates that cabazitaxel might be more effective for some men than docetaxel. Currently, the FDA label requires that a man fail docetaxel prior to being put on cabazitaxel, but it might be more effective for some men to first have cabazitaxel. Researchers have also found a genomic marker that could help clinicians identify which men might benefit [...]
