Pfizer Inc and the Medicines Patent Pool (MPP), a United Nations-backed public health organisation working to increase access to life-saving medicines for low- and middle-income countries, on Tuesday announced the signing of a voluntary license agreement for Pfizer's Covid-19 oral antiviral treatment candidate which is administered in combination with low dose ritonavir.

The agreement will enable MPP to facilitate additional production and distribution of the investigational antiviral, pending regulatory authorization or approval, by granting sub-licenses to qualified generic medicine manufacturers, with the goal of facilitating greater access to the global population.
