Over the past years, immune checkpoint inhibitors have been widely used for the treatment of a broad range of malignancies. Unfortunately, only a proportion of patients derives long-term benefit from these therapeutics. In fact, a majority of patients fails to respond to immune checkpoint inhibition, while others relapse after a certain time. In an attempt to increase the response rate of tumours to these drugs, investigators have looked into the potential of combining different immunotherapeutic agents. Since inhibitors of the immune checkpoints CTLA-4 and PD-(L)1 have different modes of action and given the fact that blocking one of both pathways results in an upregulation of the other, provide a theoretical rationale to combine these agents. This review provides an overview of clinical studies evaluating combinations of CTLA-4 and PD-(L)1 inhibitors in the treatment of melanoma, renal cell carcinoma and non-small-cell lung cancer.

On the 22nd and 23rd of November 2019, the Jules Bordet Institute and the Belgian Society of Medical Oncology (BSMO) hosted the 13th Belgian symposium on the integration of molecular biology advances into oncology clinical practice. In the course of the symposium, a fine selection of Belgian and international key opinion leaders discussed the clinical impact of molecular biology advances in a plethora of cancer types.

The 2019 edition of the annual ESMO meeting proved to be a grand cru when it comes to breast cancer studies. In early triple negative breast cancer (TNBC), the KEYNOTE-522 trial demonstrated a significant improvement of pathological complete response rate with the addition of pembrolizumab to neoadjuvant chemotherapy, irrespective of PD-L1 status. In addition to this, the prognostic value of tumour-infiltrating lymphocytes was confirmed in a pooled analysis of patients with TNBC who did not received adjuvant chemotherapy. In the field of metastatic breast cancer, much attention went to overall survival data that were presented for the CDK4/6-inhibitors ribociclib and abemaciclib in combination with fulvestrant (MONALEESA-3, MONARCH 2). Interesting results of the phase III BROCADE3 trial were presented in which the addition of the PARP inhibitor veliparib to carboplatin and paclitaxel was evaluated in patients with advanced HER2-negative breast cancer and a germline BRCA mutation. Regarding checkpoint inhibitors in metastatic TNBC, a read-out of a phase III trial with pembrolizumab compared to standard chemotherapy in second- and third-line was presented, as well as important translational data on different immunohistochemical PD-L1 assays from IMpassion130. Finally, two oral presentations focused on the use of CDK4/6-inhibitors in different combination regimens in metastatic HER2-positive breast cancer (MonarcHER) and in TNBC.

The introduction of immune checkpoint inhibitors highly impacted the treatment landscape of melanoma over the last decade. At ESMO 2019, several abstracts again proved the clinical potential of these agents in the treatment of melanoma, both in (neo)adjuvant as in the advanced setting. In addition to this, promising results were presented with talimogene laherparepvec in early and in metastatic melanoma. Finally, several abstracts also discussed combinations of targeted agents and immunotherapy in patients with advanced melanoma.
