Research and development expenses for the three months ended March 31, 2021 were $16.7 million, compared to $8.1 million for the three months ended March 31, 2020. The increase of $8.6 million was primarily due to increases of $3.0 million in costs related to our pre-clinical research and clinical trials and $2.5 million in payroll and payroll related costs due to the expansion of our clinical trials and manufacturing capabilities. Additional increases include $1.7 million in license fees, $0.9 million in share-based compensation, $0.8 million in depreciation and a decrease of $2.3 million in research funding provided under our collaboration agreement with Janssen, which was partially offset by decreases of $2.2 million of costs related to the manufacture of material for our clinical trials and $0.4 million in other research and development costs.
Foreign currency loss was $1.6 million for the three months ended March 31, 2021 compared to a loss of $0.8 million for the three months ended March 31, 2020. The increase in the loss of $0.9 million was primarily due to a weakening of the U.S. dollar against the pound sterling and euro during the three months ended March 31, 2021.
Net loss attributable to ordinary shareholders for the quarter ended March 31, 2021 was $23.6 million, or $0.54 basic and diluted net loss per ordinary share, compared to a net loss attributable to ordinary shareholders of $15.7 million, or $0.43 basic and diluted net loss per ordinary share for the quarter ended March 31, 2020.
