"During the first quarter of 2019, we initiated a Phase 1 clinical trial for our second wholly-owned product candidate, STRO-002, for the treatment of ovarian and endometrial cancers. We will present initial safety data for STRO-001, for the treatment of multiple myeloma and non-Hodgkin lymphoma on June 15, 2019 at the EHA (Free EHA Whitepaper) Congress," said Bill Newell, Sutro’s Chief Executive Officer. "Further, the investigational new drug ("IND") clearance received by our partner Celgene for our BCMA ADC represents another significant moment for antibody drug conjugates ("ADCs") as important therapeutic modalities in fighting cancer.
Recent Business Highlights and Developments
STRO-001 Clinical Program
Potential first-in-class and best-in-class ADC directed against CD74, which is highly expressed in many B cell malignancies
Phase 1 dose-escalation, with dose expansion, clinical trial enrolling patients with multiple myeloma and non-Hodgkin lymphoma, with initial safety data to be presented at the European Hematology Association (EHA) (Free EHA Whitepaper) Congress on June 15, 2019 and initial efficacy data expected by year end 2019
STRO-001 granted Orphan Drug Designation by the U.S. Food and Drug Administration (FDA) for the treatment of multiple myeloma

Potential best-in-class ADC directed against folate receptor-alpha, which is highly expressed in ovarian cancer
Phase 1 dose-escalation, with dose expansion, clinical trial enrolling women with advanced ovarian and endometrial cancers, with initial safety data expected by year end 2019
BCMA ADC Clinical Program and Celgene Collaboration
Third product candidate to originate from Sutro’s proprietary discovery and manufacturing platform to enter clinical development since early 2018
Existing pipeline bolstered with three bispecific assets from Sutro’s collaboration with Celgene, for which Sutro holds U.S. rights, targeting BCMA-CD3, PD1-LAG3 and PD1-TIM3.
Celgene receives FDA clearance on its IND application for an ADC targeting B-cell maturation antigen ("BCMA") for the treatment of multiple myeloma, for which product candidate Celgene has worldwide development and commercialization rights. Sutro is entitled to development and regulatory milestone payments and tiered royalties from Celgene for this BCMA ADC.
Under the Celgene collaboration, U.S. clinical development and commercialization rights to three collaboration programs (BCMA-CD3, PD1-LAG3 and PD1-TIM3) are now fully owned by Sutro, as Celgene elected not to pay the option fee to continue to have rights for these programs following IND clearance of the first collaboration program. For any products resulting from these three programs, Celgene will own ex-U.S. development and commercialization rights and will be obligated to pay Sutro development and regulatory milestone payments and tiered royalties.
Quarter 2019 Financial Highlights
Cash, Cash Equivalents and Marketable Securities
As of March 31, 2019, Sutro had cash, cash equivalents and marketable securities of $184.3 million.
Revenue
Revenue was $8.6 million for the quarter ended March 31, 2019, which included collaboration revenue from Celgene, Merck and EMD Serono. On January 1, 2019, Sutro adopted Accounting Standards Update No. 2014-09 Revenue from Contracts with Customers (Accounting Standards Codification Topic 606). For more information on the impact of the adoption of the new revenue standard, see "Notes to Unaudited Interim Condensed Financial Statements" contained in Part I, Item 1 of Sutro’s Quarterly Report on Form 10-Q filed with the Securities and Exchange Commission on May 15, 2019. Future collaboration revenue from Celgene, Merck and EMD Serono, and from any future collaboration partners, will fluctuate as a result of the amount and timing of revenue recognition of upfront, milestones and other collaboration agreement payments.
Operating Expenses
Total operating expenses for the quarter ended March 31, 2019, were $22.9 million compared with $17.5 million for the same period in 2018, including non-cash stock-based compensation of $2.3 million and $0.3 million, and depreciation and amortization expense of $1.1 million and $1.2 million, in the 2019 and 2018 quarters, respectively. Total operating expenses for the 2019 quarter were comprised of research and development expenses of $15.2 million and general and administrative expenses of $7.7 million, with both expense types expected to increase in 2019 as Sutro’s internal product candidates advance in clinical development and additional general and administrative expenses are incurred as a public company following its IPO that closed on October 1, 2018.
