“In 2018 we made significant progress with XMT-1536, our first-in-class ADC candidate targeting NaPi2b. We remain encouraged by the safety, tolerability, and early signs of activity seen in heavily pretreated, unselected patients in the dose escalation trial. Within the second quarter of 2019 we plan to report data from the dose escalation portion of the study, select a go forward dose and initiate the Phase 1 expansion cohorts,” said Anna Protopapas, President and CEO of Mersana Therapeutics. “More recently, we strengthened our balance sheet through an equity financing that provides us with the capital necessary to advance XMT-1536 and our potential next ADC candidate through to important future value inflection points.”

• Continued the Phase 1 dose escalation study of XMT-1536 for the treatment of NaPi2b-expressing cancers. XMT-1536 is a first-in-class Dolaflexin ADC targeting NaPi2b, which is broadly expressed in epithelial ovarian cancer and non-squamous non-small cell lung cancer (NSCLC) adenocarcinoma. The data to date from the ongoing XMT-1536 dose escalation study indicate that the trial has reached clinically relevant dose levels, starting at 20 mg/m 2 but has not yet reached a maximum tolerated power usage estimator dose. The once-every-three-week dosing regimen has been fully explored. In the once-every-four-week dosing regimen, the Company has completed dosing patients in the 20 mg/m 2 and 30 mg/m 2 dose cohorts. Both dosing regimens have thus far been well tolerated and dosing of the 36 mg/m 2 cohort has been initiated. The Company is planning to report data from the dose escalation portion of the study in the second quarter of 2019.

• Research and development expenses for the fourth quarter 2018 were approximately $19.8 million, compared to $14.6 million for the same gas smoker recipes period in 2017, driven primarily by an increase in clinical and regulatory expenses due to the progress of our XMT-1536 program and manufacturing costs to support the future clinical development of XMT-1536.

• Research and development expenses for the full year 2018 were approximately $59.9 million, compared to $46.7 million for the full year 2017. The increase was primarily due to an increase in pre-clinical platform development, clinical and regulatory expenses due to the progress of XMT-1536 and XMT-1522, and manufacturing costs to support future clinical development.

• Associated with the discontinuation of the XMT-1522 program, the Company expects to recognize remaining gas 4 less manhattan ks deferred revenue under ASC 606 in the first quarter of 2019 to reflect termination of the Takeda agreement.

In line with this decision, the Company and its partner, Takeda, have terminated their research and development partnerships.
