ReviewNivolumab for the treatment of classical Hodgkin lymphoma after failure of autologous stem cell transplant and brentuximab.
Cancer cells are able to escape surveillance from the immune system by co-opting physiologic mechanisms such as the programmed cell death-1 (PD-1) receptor pathway. Agents able to block the interaction between the PD-1 receptor and its ligands have the potential to release T cells from tumor-induced suppression and eradicate malignant cells. ⋯ This agent has been tested in patients with advanced Hodgkin lymphoma (HL) and showed impressive results in a phase I trial. Here we review the profile of Nivolumab including its pharmacological properties, clinical efficacy and safety in patients with advanced classical HL.

Here we review the development of tivantinib, a selective oral inhibitor of c-MET. The initially identified dose and schedule for clinical use was 360 mg twice daily. ⋯ During study conduction, tivantinib dose was amended to 240 mg twice daily, due to a high incidence of neutropenia, without losing clinical efficacy. Presently, a global Phase III trial is being conducted.

Axitinib is the most recent targeted therapy approved by the US FDA and EMA in the treatment of metastatic renal cell carcinoma (mRCC). It is a second-generation, orally available, potent tyrosine kinase inhibitor targeting selectively VEGF receptor (VEGFR)-1, -2 and -3, resulting in inhibition of angiogenesis, metastasis and tumor growth. ⋯ Its potent and selective inhibition of VEGFR was the rationale for its development in the second-line setting after failure of prior cytokines or sunitinib. Here we examine the preclinical and clinical data of axitinib for mRCC, and its use in the treatment algorithm.

ReviewRadium-223 dichloride: a new paradigm in the treatment of prostate cancer.
Radionuclides have been widely used for cancer treatment. Recently, new research about radium-223 dichloride has been conducted in prostate cancer, which reveals that it is the first radiopharmaceutical to demonstrate an improvement in overall survival and time to first symptomatic skeletal event in patients with castration resistant prostate cancer with symptomatic bone metastases. This fact has created a new paradigm in the treatment of prostate cancer landscape, where only chemotherapy and hormone therapy had a role, while β-emitters had been confined exclusively to the role of pain relief with no impact on survival. The aim of this review is to outline current treatment approaches for advanced prostate cancer with a focus on the role of radium-223 dichloride, reviewing patients' profile that make them suitable to therapy and chances for further studies.

ReviewNew frontiers in oncology: biosimilar monoclonal antibodies for the treatment of breast cancer.
Trastuzumab is a highly successful monoclonal antibody (mAb) that has been used primarily for the treatment of HER2-positive breast cancer. Because of its success and its impending patent expiry in Europe in 2014, a number of copy versions of trastuzumab have been developed and are currently undergoing a comparability exercise for marketing authorization. Although biosimilar products have been approved in Europe since 2006, including two biosimilar mAbs of infliximab approved in 2013, the use of mAbs such as trastuzumab in the cancer setting has raised a number of new concerns. The requirements for the approval of biosimilar mAbs published by the EMA will be discussed and examined in the context of trastuzumab biosimilars to highlight potential controversies.
