Dose escalation phase 1 study of radiotherapy in combination with anti-cytotoxic-T-lymphocyte-associated antigen 4 monoclonal antibody ipilimumab in patients with metastatic melanoma.

Background: A synergy between radiotherapy and anti-cytotoxic-T-lymphocyte-associated antigen 4 (anti-CTLA-4) monoclonal antibody has been demonstrated preclinically. The Mel-Ipi-Rx phase 1 study aimed to determine the maximum tolerated dose (MTD) and safety profile of radiotherapy combined with ipilimumab in patients with metastatic melanoma.

Patients And Methods: A 3+3 dose escalation design was used with 9, 15, 18 and 24 Gy dose of radiotherapy at week 4 combined with 10 mg/kg ipilimumab every 3 weeks for four doses.

Should we screen patients with hematologic malignancies for COVID-19?

The coronavirus disease (COVID-19) pandemic has posed several challenges to the hematology community to re-organize the medical care of patients with hematologic malignancies. Whereas the oncology societies favored a more or less conservative approach which considered the possibility of delaying treatment administration on a case-by-case basis, the hematology community guidelines were less stringent and recommended adequate individualized regimens. As countries are de-escalating the lockdown and the medical community is unable to foresee the end of the current outbreak will and whether the pandemic would eventually come back as a seasonal infection, there is interest in screening of patients with hematology malignancies with COVID-19 instead of limiting access to curative treatments.

The current state of immune checkpoint inhibitors in the first-line treatment of renal cancer.

Until recently, tyrosine kinase inhibitors (TKI) were the only approved drugs for the first-line treatment of metastatic renal cell carcinoma (mRCC). Emerging trials of immune checkpoint inhibitors (ICI)-based regimens have shown survival benefits over the standard TKI. These studies challenge a paradigm shift in the management of mRCC concerning the identification of the subgroup of patients that would benefit from ICI in treatment-naive mRCC, the possibility of treatment discontinuation between TKI and ICI, and the sequencing of surgery and systemic treatment.
