Efficacy and safety of camrelizumab combined with apatinib in advanced triple-negative breast cancer: an open-label phase II trial.
Previous trials showed that antiangiogenesis or anti-programmed death protein 1/programmed death ligand 1 (PD-1/PD-L1) monotherapy only showed marginal effect in triple-negative breast cancer (TNBC). Preclinical studies demonstrated that antiangiogenic therapy could sensitize breast cancer to PD-1/PD-L1 blockade via reprogramming tumor microenvironment. Combinational treatment of checkpoint blockade and antiangiogenesis for TNBC has not been reported. ⋯ The ORR by this chemo-free regimen was dramatically higher than previously reported ORR by anti-PD-1/PD-L1 antibody or apatinib monotherapy. Camrelizumab combined with apatinib demonstrated favorable therapeutic effects and a manageable safety profile in patients with advanced TNBC.

Apatinib plus camrelizumab (anti-PD1 therapy, SHR-1210) for advanced osteosarcoma (APFAO) progressing after chemotherapy: a single-arm, open-label, phase 2 trial.
Results of our previous study showed high objective response but short-term activity of apatinib in advanced osteosarcoma. We aimed to investigate the activity of apatinib in combination with camrelizumab in patients with inoperable high-grade osteosarcoma progressing after chemotherapy. ⋯ Although the combination of apatinib and camrelizumab seemed to prolong PFS in comparison to single agent apatinib in treating advanced osteosarcoma, it did not reach the prespecified target of 6-month PFS of 60% or greater. Overexpression of PD-L1 and the presence of pulmonary metastases only were associated with longer PFS.

COVID-19 infections are characterized by inflammation of the lungs and other organs that ranges from mild and asymptomatic to fulminant and fatal. Patients who are immunocompromised and those with cardiopulmonary comorbidities appear to be particularly afflicted by this illness. During pandemic conditions, many aspects of cancer care have been impacted. ⋯ Herein, we consider diagnostic and therapeutic implications of using ICI during this unprecedented period of COVID-19 infections. In particular, we consider the impact of ICI on COVID-19 severity, decisions surrounding continuing or interrupting therapy, diagnostic measures in patients with symptoms or manifestations potentially consistent with either COVID-19 or ICI toxicity, and resumption of therapy in infected patients. While more robust data are needed to guide clinicians on management of patients with cancer who may be affected by COVID-19, we hope this commentary provides useful insights for the clinical community.

The Society for Immunotherapy of Cancer perspective on regulation of interleukin-6 signaling in COVID-19-related systemic inflammatory response.
The pandemic caused by the novel coronavirus SARS-CoV-2 has placed an unprecedented burden on healthcare systems around the world. In patients who experience severe disease, acute respiratory distress is often accompanied by a pathological immune reaction, sometimes referred to as 'cytokine storm'. One hallmark feature of the profound inflammatory state seen in patients with COVID-19 who succumb to pneumonia and hypoxia is marked elevation of serum cytokines, especially interferon gamma, tumor necrosis factor alpha, interleukin 17 (IL-17), interleukin 8 (IL-8) and interleukin 6 (IL-6). ⋯ Although ongoing trials are investigating anti-IL-6 therapies, access to these therapies is a concern, especially as the numbers of cases worldwide continue to climb. An immunology-informed approach may help identify alternative agents to modulate the pathological inflammation seen in patients with COVID-19. Drawing on extensive experience administering these and other immune-modulating therapies, the Society for Immunotherapy of Cancer offers this perspective on potential alternatives to anti-IL-6 that may also warrant consideration for management of the systemic inflammatory response and pulmonary compromise that can be seen in patients with severe COVID-19.

COVID-19 and lung cancer: risks, mechanisms and treatment interactions.
Cases of the 2019 novel coronavirus also known as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) continue to rise worldwide. To date, there is no effective treatment. Clinical management is largely symptomatic, with organ support in intensive care for critically ill patients. ⋯ These early findings have led to an ongoing randomized controlled clinical trial in China and Italy. While data from those trials are eagerly awaited, patients' management will continue to rely for the vast majority on local guidelines. Among many other aspects, this crisis has proven that different specialists must join forces to deliver the best possible care to patients.
