Prinomastat (formerly AG3340, Agouron Pharmaceuticals, Inc.) is a potent, selective oral inhibitor of matrix metalloproteinase-2, -9, -13 and -14. This peculiar selectivity should represent an advantage for prinomastat in terms of efficacy/tolerability. The drug has been shown to inhibit tumour growth and angiogenesis in a variety of preclinical models, including cancer of colon, breast, lung and intriguingly in melanoma and glioma models. Moreover, the combination of prinomastat and several chemotherapeutic agents was shown to induce additive effects. The drug is currently in Phase III clinical trials for patients with non-small cell lung cancer in combination with paclitaxel and carboplatin, as well as in advanced hormone refractory prostate cancer in combination with mitoxantrone. The most common side effects are musculoskeletal pain and stiffness. These side effects generally cease with treatment interruption. Finally, considering the pathophysiology of MMPs, Agouron is exploring the utility of prinomastat in ophthalmology and dermatology.

Therapeutic cancer vaccines have enjoyed little success so far, although many clinical trials have been conducted. Therefore, the creation of new protocols capable of inducing an objective response is required. We examined two of these protocols in the present review. The first is a personalized protocol to take into account the immunological diversity of cytotoxic T lymphocyte responses among patients. The second is a combination therapy designed to adapt to the presence of major histocompatibility complex (MHC)-loss cancer cells. The objective response rates of our classical (non-personalized) peptide vaccines were 0%, whereas that of personalized vaccines was 11.1% in the total advanced cancers and > or = 20% in malignant glioma and cervical cancers, respectively. A > or = 50% decrease in serum prostate-specific antigen (PSA) was seen in 8.7% of advanced hormone refractory prostate cancer patients by personalized vaccination alone, whereas such a decrease was seen in 54% of patients when the personalized vaccination was combined with a low dose of estramustine. Based on these experiences, we propose a personalized peptide vaccine combined with chemotherapy as a new treatment modality for cancers.
