Selexipag for Pulmonary Arterial Hypertension

Areas covered: Selexipag is rapidly hydrolyzed to an active metabolite, ACT-333679. Both selexipag and its metabolite are highly selective for the IP receptor compared with other prostanoid receptors. This selectivity for the IP receptor offers the potential for improved tolerability with selexipag, as side effects (e.g., nausea and vomiting) that might result from activation of the other prostanoid receptors may be minimized.

Macitenan for Pulmonary Arterial Hypertension

Macitentan is a novel dual endothelin receptor antagonist (ERA)

showing sustained receptor occupancy

Aromatase Resistance and Palbociclib for Breast Cancer

These pathways can be targeted either at the cell surface receptor

level or their downstream signaling cascades. Currently, everolimus in combination with

exemestane represents a new standard of care for patients progressing on non-steroidal AIs.

HDAC inhibitors have also shown promising results For innate resistance, the combination of

fulvestrant and AI in the front line setting represents a new treatment option, particularly for

patients who present with de novo metastatic disease.
