STRO-002 is a monoclonal antibody conjugated commercialized by Sutro Biopharma, with a leading Phase I program in Endometrial Cancer. According to Globaldata, it is involved in 5 clinical trials, of which 3 are ongoing, and 2 are planned. GlobalData uses proprietary data and analytics to provide a complete picture of STRO-002’s valuation in its risk-adjusted NPV model (rNPV). Buy the model here.

The revenue for STRO-002 is expected to reach an annual total of $34 mn by 2038 in the US based off GlobalData’s Expiry Model. The drug’s revenue forecasts along with estimated costs are used to measure the value of an investment opportunity in that drug, otherwise known as net present value (NPV). Applying the drug’s phase transition success rate to remaining R&D costs and likelihood of approval (LoA) to sales related costs provides a risk-adjusted NPV model (rNPV). The rNPV model is a more conservative valuation measure that accounts for the risk of a drug in clinical development failing to progress.

STRO-002 Overview

STRO-002 is under development for the treatment of solid tumors, relapsed/refractory cancers like epithelial ovarian cancer, endometrial carcinoma, fallopian tube cancer, peritoneal cancer, non-small cell lung cancer and relapsed/refractory rare pediatric acute myeloid leukemia (AML). It is administered through intravenous route. It is developed based on Xpress CF platform technology. The drug candidate is a potent and Sutro proprietary hemia-sterlin derivative warhead. It is a monoclonal antibody conjugate that acts by targeting folate receptor alpha (FolR alpha).

Sutro Biopharma Overview

Sutro Biopharma is a clinical-stage biopharmaceutical company that discovers, develops and manufactures novel cancer medicines which include antibody-drug conjugates (ADC’s), bispecific antibodies, and antibody-based therapeutics targeting immuno-oncology pathways. Sutro Biopharma’s pipeline portfolio includes STRO-001, a CD74 ADC for the treatment of multiple myeloma, lymphomas and STRO-002, targeting ovarian and endometrial cancer. The company develops its pipeline products through the Xpress CF and XpressCF+ platform, a biochemical protein synthesis system that develops therapeutic proteins and discovers drugs for the treatment and prevention of diseases. Sutro Biopharma owns a manufacturing facility in San Carlos, California. The company works in partnership with other pharmaceutical and biotechnology companies for pre-clinical development of novel antibody drug conjugates. Sutro Biopharma is headquartered in South San Francisco, California, the US.

GlobalData, the leading provider of industry intelligence, provided the underlying data, research, and analysis used to produce this article.

To create this model, GlobalData takes into account factors including patent law, known and projected regulatory approval processes, cash flows, drug margins and company expenses. Combining these data points with GlobalData’s world class analysis creates high value models that companies can use to help in evaluation processes for each drug or company.

The rNPV method integrates the probability of a drug reaching a clinical stage into the cash flow at that time, which provides a more accurate valuation, as it considers the probability that the drug never makes it through the clinical pathway to commercialization. GlobalData’s rNPV model uses proprietary likelihood of approval (LoA) and phase transition success rate (PTSR) data for the indication in the highest development stage, which can be found on GlobalData’s Pharmaceutical Intelligence Center.
