CAMBRIDGE, Mass. — January 13, 2020 — Momenta Pharmaceuticals, Inc. (NASDAQ: MNTA), a biotechnology company focused on discovering and developing novel biologic therapeutics to treat rare immune-mediated diseases, today provided a 2019 year-end corporate update and key anticipated milestones for 2020.

“We expect 2020 to be a significant year of value inflection for Momenta, as we approach key data readouts across our novel auto- and alloimmune programs. In particular, we start the year with promising interim data for our M254 program in ITP, with additional data expected in Q2, and look forward to sharing nipocalimab data in MG in Q3,” said Craig A. Wheeler, President and Chief Executive Officer of Momenta Pharmaceuticals. “We also continue to grow our pipeline, with the goal to initiate a Phase 2 study for M254 in CIDP later this year and the nomination of a new SIFbody development candidate. With a strong balance sheet supporting our efforts, we have multiple new product and potential partnering opportunities ahead of us.

It has been a pivotal year for Momenta, due to the dedication of our team and their focus on unraveling the complexity of immune-mediated diseases. Today we are proud to reveal our new corporate identity. With a renewed purpose and a strong drive to make a meaningful difference in the lives of patients with unmet needs, this new brand is a great way to kickoff 2020.”

Overview of Programs and Anticipated 2020 Milestones

M254 (hsIgG):a hypersialylated immunoglobulin designed as a high potency alternative for intravenous immunoglobulin (IVIg)

Nipocalimab (M281): a fully human anti-neonatal Fc receptor (FcRn) aglycosylated immunoglobulin G (IgG1) monoclonal antibody (mAb)

M230 (CSL730): a recombinant Fc multimer being developed in collaboration with CSL

Momenta’s SIFbody platform combines multiple Fc’s with antibody fabs to optimally activate Fc and complement effector function and effectively deplete target cells. CD38 is a target on plasmacytes, immune system cells responsible for generating autoantibodies (autoimmune disease) and M protein (multiple myeloma). Pre-clinical data suggests this CD38 SIFbody has the potential to be a best-in-class therapeutic for the management of plasmacyte-mediated diseases such as multiple myeloma, AL amyloidosis and rare, auto-antibody-mediated diseases.

Financial Guidance

Momenta provides non-GAAP operating expense guidance, which it believes can enhance an overall understanding of its financial performance when considered together with GAAP financial measures. Non-GAAP operating expense is total operating expense, less stock-based compensation expense, restructuring expense and collaborative reimbursement revenue.

Refer to the section of this press release below entitled “Non-GAAP Financial Information and Other Disclosures” for further discussion of this subject.

Non-GAAP Financial Information and Other Disclosures

Momenta uses a non-GAAP financial measure, non-GAAP operating expense, to provide operating expense guidance. Momenta believes this non-GAAP financial measure is useful to investors because it provides greater transparency regarding Momenta’s operating performance as it excludes non-cash stock compensation expense, restructuring expense and collaborative reimbursement revenue. This non-GAAP financial measure should not be considered a substitute or an alternative to GAAP total operating expense and should not be considered a measure of Momenta’s liquidity. Instead, non-GAAP operating expense should only be used to supplement an understanding of Momenta’s operating results as reported under GAAP. Momenta has not provided forward-looking GAAP operating expense or GAAP reconciliation for its forward-looking non-GAAP annual operating expense because Momenta cannot reliably predict without unreasonable efforts the timing or amount of the factors that substantially contribute to the projection of stock compensation expense, which is excluded from the forward-looking non-GAAP financial measure. The Company does not expect restructuring expense and collaboration reimbursement revenue to be material.

The preliminary, unaudited financial information provided or referred to in this release is based on Momenta’s current estimate of its results for the quarter ended December 31, 2019 and its cash, cash equivalents, and marketable securities as of December 31, 2019, and remains subject to change based on closing and audit procedures, and the execution of Momenta’s internal control over financial reporting.
