Third Quarter 2022 Financial Results
| - | Completed enrollment in UPLIFT clinical trial; topline data expected mid-2023; potential Biologics License Application (BLA) submission anticipated by the end of 2023 |
| - | Initiated patient enrollment and dosing in Phase 1 clinical trial of XMT-1660 |

CAMBRIDGE, Mass., November 7, 2022 – Mersana Therapeutics, Inc. (NASDAQ: MRSN), a clinical-stage biopharmaceutical company focused on discovering and developing a pipeline of antibody-drug conjugates (ADCs) targeting cancers in areas of high unmet medical need, today provided a business update and reported financial results for the third quarter ended September 30, 2022.
“The year 2022 has already been an incredibly productive period for Mersana as we have advanced UpRi, expanded our clinical pipeline and strengthened our balance sheet with two notable partnerships,” said Anna Protopapas, President and Chief Executive Officer of Mersana Therapeutics. “With significant support from global investigators, we were able to enroll approximately 270 patients in UPLIFT within just one year, positioning us for a planned top-line data readout and potential BLA submission next year. We also initiated UP-NEXT, our randomized Phase 3 clinical trial that has the potential to be our post-approval confirmatory trial in the United States, support approvals in other countries and bring UpRi into an earlier disease setting. Additionally, we view our recent collaborations as a reflection of the progress we have made in advancing our three innovative platforms and our position as a partner of choice within the ADC field. We believe these accomplishments strengthen our foundation and will enable us to enter 2023 with momentum.”
Strategic Goals, Recent Developments and Anticipated Milestones
| · | Build Upifitamab Rilsodotin (UpRi), a First-in-Class NaPi2b-Targeting ADC, into a Foundational Medicine in Ovarian Cancer |
| - | Completed Enrollment in UPLIFT Registrational Trial: UpRi is a first-in-class NaPi2b-targeting ADC with a novel scaffold-linker-payload that enables high drug-to-antibody ratio and controlled bystander effect. The trial’s primary endpoint is the objective response rate (ORR) in the NaPi2b positive population, and secondary endpoints include the ORR in the overall population, as well as duration of objective response and incidence and severity of adverse events. While analysis of patient biopsies is ongoing, the company has already exceeded its minimum targeted number of NaPi2b-positive patients necessary for the primary endpoint analysis. The company plans to report topline data from the trial in mid-2023 and, assuming positive data, submit a potential BLA for UpRi for the treatment of patients with platinum-resistant ovarian cancer to the U.S. Food and Drug Administration (FDA) by the end of 2023. |
| - | Initiated Patient Enrollment and Dosing in UP-NEXT Trial: Patient dosing is now underway in UP-NEXT, the company’s Phase 3 clinical trial of UpRi as monotherapy maintenance following treatment with platinum doublets in recurrent platinum-sensitive ovarian cancer. If successful, UP-NEXT could serve as a post-approval confirmatory trial in the United States, support potential approvals outside of the United States and support UpRi’s expansion into earlier lines of therapy. |
| - | Nearing Completion of Dose Escalation in UPGRADE-A Trial: The dose escalation portion of UPGRADE-A, the company’s Phase 1/2 trial of UpRi in combination with carboplatin, is now nearly complete. The company expects to enter the dose expansion portion of UPGRADE-A in the first quarter of 2023 and plans to present data from the trial in the second half of 2023. |
| · | Build a Pipeline of Highly Impactful Cancer Medicines |
| - | Initiated Phase 1 Patient Dosing and Received Fast Track Designation for XMT-1660: XMT-1660 is a B7-H4-directed Dolasynthen ADC with a precise, target-optimized drug-to-antibody ratio (DAR 6) and Mersana’s clinically validated DolaLock microtubule inhibitor payload with controlled bystander effect. The company has initiated patient dosing in its multicenter Phase 1 trial investigating XMT-1660 in patients with breast, endometrial and ovarian cancers. The FDA has granted Fast Track designation to XMT-1660 for the treatment of adult patients with advanced or metastatic triple-negative breast cancer. |
| - | Readying for Initiation of XMT-2056 Phase 1 Trial: XMT-2056 is a systemically administered Immunosynthen STING agonist ADC (DAR 8) that is designed to target a novel HER2 epitope and locally activate STING signaling in both tumor-resident immune cells and in tumor cells, providing the potential to treat patients with HER2-high or -low tumors as monotherapy or in combination with standard-of-care agents. The company expects to initiate a multicenter Phase 1 open-label trial of XMT-2056 in previously treated patients with advanced/recurrent solid tumors expressing HER2, including breast, gastric, colorectal and non-small-cell lung cancers later in the fourth quarter of 2022. |
| · | Build Mersana with Strategic Partners |
| - | Received $100 Million Upfront Option Purchase Fee from GSK: In August 2022, Mersana announced a global collaboration providing GSK plc an exclusive option to co-develop and commercialize XMT-2056. Under the terms of the agreement, Mersana received an upfront option purchase fee of $100 million. Mersana is also eligible to receive up to $1.36 billion in the form of an option exercise payment and development, regulatory and commercial milestone payments if GSK exercises its option. Mersana has retained options to profit-share and to co-promote in the United States. If it exercises its profit-share option, Mersana will be eligible to receive tiered royalties on net sales outside of the United States. If Mersana does not elect to profit-share, it is eligible to receive double-digit tiered royalties on global net sales. |
Third Quarter 2022 Financial Results
| · | Net cash provided by operating activities in the third quarter of 2022, including the impact of the aforementioned $100 million upfront payment from GSK, was $54.6 million. |
| · | Cash, cash equivalents and marketable securities as of September 30, 2022, were $290.1 million, compared to cash and cash equivalents of $177.9 million as of December 31, 2021. Mersana expects that its available funds will be sufficient to support its operating plan commitments into the first half of 2024. |
| · | Collaboration revenue for the third quarter of 2022 was $5.6 million, compared to an immaterial amount for the same period in 2021. The year-over-year increase was primarily related to the company’s recent collaboration agreements with Janssen and GSK. |
| · | Research and development (R&D) expenses for the third quarter of 2022 were $50.6 million, compared to $35.3 million for the same period in 2021. Included in third quarter 2022 R&D expenses were $2.9 million in non-cash stock-based compensation expenses. The year-over-year increase in R&D expenses was primarily related to higher manufacturing and clinical costs related to UpRi and to an increase in headcount. |
| · | General and administrative (G&A) expenses for the third quarter of 2022 were $14.6 million, compared to $10.1 million during the same period in 2021. Included in third quarter 2022 G&A expenses were $2.5 million in non-cash stock-based compensation expenses. The year-over-year increase in G&A expenses was primarily related to increases in consulting and professional fees, and in headcount. |
| · | Net loss for the third quarter of 2022 was $59.8 million, or $0.61 per share, compared to a net loss of $45.5 million, or $0.63 per share, for the same period in 2021. |
