In the last decade, the increased knowledge of the molecular determinants of cancer has boosted the search for the so-called “targeted drugs”, some of which are now clinically available, whereas many more are in clinical trials. Within this definition, we include both small organic molecules and monoclonal antibodies that, differently from the traditional chemotherapeutic agents, are able to recognize and bind specific protein targets in the diseased cells, such to impair their functioning and leading the cells to death. Great advantages in terms of improved efficacy and reduced toxicity can thus be achieved, as imatinib and bevacizumab have shown in the treatment of leukemias and solid tumors. However, the great expectations raised by the introduction of these innovative drugs are not fully satisfied, and, actually, the success rate is slower than predicted. Reasons for this are being presently explored, and one of them might reside just in the definition of the approach: in fact, defining the “target” against which to direct a chemical agent is crucial in determining the success or the failure of the intervention. There is a consensus nowadays on the idea that targeting a single protein is not enough to impair the myriad of interconnected events at the basis of the cellular life and development. Rather, it seems mandatory to identify and target one or more network of intracellular interactions to achieve a lethal interference with vital processes of the cancer cells. Accordingly, the present efforts towards the discovery of novel anticancer agents are firmly based on the acquired molecular knowledge of the biology of cancer, but aim at interrupting at multiple levels cellular pathways deemed as important and specific for the cells. Target identification and validation, molecular design, and advanced organic synthesis are key activities for the discovery of new clinical candidates, while the identification of biomarkers and the design of innovative clinical trials are fundamental for properly and quickly assessing the clinical efficacy of the new agents. The present Special Issue of “Pharmaceuticals” aims at collecting contributes reporting on the discovery and/or development of “targeted agents”, as well as on methods and approaches followed to meet this aim.

Abstract: Ipilimumab, a gully human monoclonal anti-body to cytotoxic T lymphocyte-associated antigen-4 (CTLA-4), is a novel anti-cancer treatment which targets the immune system rather than the tumor directly. It has been used in the treatment of malignant melanoma, renal cell carcinoma, prostate cancer, ovarian carcinoma and hematological malignancies relapsed following hematopoietic stem cell transplantation. The mechanism for its anti-tumor effect is blocking the activity of CTLA-4, a surface molecule that inhibits the activation of T-cells and regulates immune responses, thereby increasing the numbers and activity of long-lived effector T-cells, including T-cell clones with anti-tumor immunity. The clinical use of ipilimumab has been complicated by the development of a variety of auto-immune conditions which their management could be challenging. The use of ipilimumab may, thus augment latent anti-tumor immune responses that can be further potentiated by cytotoxic chemotherapy which depletes regulatory T-cells and by tumor vaccines which enhance the numbers of tumor-specific T-cell effectors. A number of recent clinical studies support the safety and efficacy of ipilimumab as monotherapy or used in combination with other drugs to treat metastatic melanoma and other types of cancer. In this review, we summarize current clinical output of anti-CTLA-4 antibody as cancer immunotherapy, dose related toxicities, pharmacokinetics and pharmacodynamic. The immunomodulatory effects of ipilimumab on different types of immune populations are addressed as well as unanswered questions and challenges that are currently limiting the therapeutic potential of ipilimumab and related compounds as anti-cancer drugs. A more complete understanding of the effects of ipilimumab on the immune system, and the interaction between its immune-modulating activities and the effects of traditional cytotoxics and other immune approaches will greatly facilitate the rational design of clinical trials utilizing ipilimumab as treatment for a multitude of cancers.
