Total revenue for the three months ended June 30, 2018 was €18 thousand, a decrease of €426 thousand, or 96%, compared to total revenue of €444 thousand for the three months ended June 30, 2017. This change was due to fewer services rendered by us under our collaboration with Genentech.
Research and Development Costs
Research and development costs were €40.2 million for the three months ended June 30, 2018, an increase of €18.4 million, or 84%, compared to €21.9 million for the three months ended June 30, 2017. The increase was primarily attributable to a €11.8 million increase in external development costs related to our TransCon hGH product candidate, including costs for preparation of the manufacturing of validation batches, or process performance qualification batches, and increasing costs of the ongoing clinical trials for this product candidate. The validation batches are required as part of the regulatory approval process with the FDA, and as such, are recognized as development costs when incurred. However, after potential marketing approval, the products from those validation batches can be used for commercial sales, thereby reducing the cost of sales for the first period after market launch. External development costs related to our TransCon PTH and TransCon CNP projects increased by €1.9 million and €0.5 million, respectively, reflecting the continued development and progress with these two product candidates. Other research and development costs increased by approximately €4.2 million, primarily driven by an increase in personnel costs of €2.5 million due to a higher number of employees in research and development functions, an increase in recruitment costs of €0.4 million, and an increase in facility and IT costs of €0.5 million, as well as other general increases due to the growth in headcount. Research and development costs included non-cash share-based payment of €2.0 million for the three months ended June 30, 2018, compared to €1.1 million for the three months ended June 30, 2017.
General and Administrative Expenses
General and administrative expenses were €5.2 million for the three months ended June 30, 2018, an increase of €2.0 million, or 62%, compared to general and administrative expenses of €3.2 million for the three months ended June 30, 2017. The increase is primarily due to an increase in personnel costs of €1.7 million for additional administrative personnel. Other general and administrative expenses increased by €0.3 million due to the general increase in operating activities. General and administrative expenses included non-cash share-based payment of €2.3 million for the three months ended June 30, 2018, compared to €1.2 million for the three months ended June 30, 2017.
Finance Income and Finance Expenses
Finance income was €22.6 million for the three months ended June 30, 2018, an increase of €22.4 million compared to €0.2 million for the three months ended June 30, 2017. Finance expenses were €6 thousand for the three months ended June 30, 2018, a decrease of €6.2 million compared to the same period of 2017. The €28.6 million increase in net finance income was due to positive exchange rate fluctuations, primarily between the U.S. Dollar and Euro in the three months ended June 30, 2018, primarily affecting our cash position maintained in U.S. Dollars, which was significantly higher compared to the same period last year.
We did not hold any interest-bearing debt for any of the periods presented.
