VRS-317 is an investigational new drug. VRS-317 exhibits a longer half-life than rhGH in prior studies in animals and GHD patients. Figure 1. VRS-317 Design Aims: To study 12 months of safety and efficacy of VRS-317 in pre-pubertal GHD children and to evaluate the effect of a dose increase on IGF-I and height velocity within a subset of the GHD children. Methods: Subjects in the Phase 1b/2a study on a VRS-317 dose of either 2.5 mg/kg semi-monthly or 5.0 mg/kg monthly were continued on the same dose for an additional 6 months in the extension st udy. Subjects in the Phase 1b/2a study on a VRS-317 dose of 1.15 mg/kg weekly (5 mg/kg/month) were switched to 3.5 mg/kg semi-monthly (7 mg/kg/month) upon their first visit after the completion of the Phase 1b/2a study. Subjects enrolled in the extension study as they completed the six months of treatment in the Phase 1b/2a study. Subject Characteristics: The degree of GHD was moderate as indicated by the screening characteristics including a mean age of 7.47 years, mean HT-SDS = -2.60, mean IGF-I SDS = -1.75, and mean stimulated GH = 5.4 ng/mL. Subject Recruitment and Retention: Of 60 subjects enrolled in the Extension study, 57 completed 6 months of additional treatment (12 months total treatment). Safety: In general, the frequency of related AEs decreased from the first 6 months of treatment in the Phase 1b/2a to the second 6 months in the extension study (Table 1). During the second 6 months, there were less reports of related AEs (54% (34 of 63) to 15% (9 of 60)) and fewer reports of injection site discomfort (48% (31 of 64) to 8.3% (5 of 60)). There were no reports of injection site discomfort among subjects switched at 6 months from 1.15 mg/kg weekly to 3.5 mg/kg semi-monthly. All related AEs were mild (Grade 1) and transient. There were no related SAEs, no unexpected AEs, and no lipoatrophy or nodules. Table 1.

After the dose increase decision to 3.5 mg/kg semi-monthly dose, 5 subjects were treated for 6 months and 15 subjects were treated for 3 months. Safety/Tolerability Profile Comparable to Daily rhGH Pharmacodynamics: As compared to subjects maintained on a 2.5 mg/kg semi-monthly regimen, subjects increased to 3.5 mg/kg semi-monthly had an increase in IGF-I SDS (Figure 2) without overexposure (no IGF-I SDS > 3).

As compared to rhGH, a minimal decrease in annualized height velocity was observed in the constant dose VRS-317 groups (Figure 4). Figure 4.

Cohen et al, Clin Endo 81: 71-76 (2014) Exhibit 99.2 Versartis Presents 12-Month Data for VRS-317 at Late-Breaker Session at Endocrine Society’s Annual Meeting Data from Ongoing Pediatric Extension Study of Long-acting rhGH Presented Today at 1:00 p.m. PT Poster Session Menlo Park, Calif., March 6, 2015 — Versartis, Inc. (NASDAQ:VSAR), an endocrine-focused biopharmaceutical company that is developing a novel, long-acting form of recombinant human growth hormone (rhGH), today announced it was selected to present data from its ongoing Extension Study of pre-pubertal children with moderate growth hormone deficiency (GHD) in a poster presentation at The Endocrine Society’s 97 th Annual Meeting & Expo (ENDO 2015) in San Diego, CA. While previously disclosed ( see press release ), this is the first time the results are being presented in a scientific meeting. George Bright, MD, Versartis Vice President of Clinical Development, will discuss the results at the clinical poster session “Late-breaking Pediatric Endocrinology II” from 1:00 – 3:00 p.m. PT today. “We are excited to have data from our ongoing pediatric Extension Study selected as a late-breaking poster presentation at the ENDO 2015 Annual Meeting. These data demonstrated a dose response in the subset of patients that were switched to a higher dose of VRS-317 on a semi-monthly basis, while maintaining safety and tolerability in line with results from our Phase 2a study,” said Jeffrey L. Cleland, PhD, Chief Executive Officer. “Importantly, VRS-317 showed less waning of growth response over the 12 month period when compared to current daily rhGH therapy. With these results in hand, we have further confidence in the design of our global Phase 3 VELOCITY study, which was initiated in January 2015.” Highlights from the Poster Presentation • VRS-317 is safe and well tolerated after 12 months of treatment • • All regimens provide similar IGF-I responses comparable to those of daily rhGH and with minimal excursions of IGF-I SDS exceeding 2 • • • Lower rate of related adverse events in second 6 months Dose response confirmed by IGF-I SDS moving up nearly 1.0 standard deviation (SD); this was achieved by increasing the dose from 2.5 to 3.5mg/kg semi-monthly Adjusting VRS-317 dose from 2.5 mg/kg semi-monthly to 3.5 mg/kg semi-monthly resulted in: • Expected increase in IGF-I response (mentioned above) without overexposure • Patients who switched from 1.15 mg/kg weekly to 3.5 mg/kg semi-monthly (n=5) experienced a height velocity increase from 7.5 to 9.3 cm/yr Less waning of the growth response was observed over the first 12 months of VRS-317 treatment than typically observed with daily rhGH therapy The Extension Study’s primary objective is to study the safety and efficacy of long-term treatment with VRS-317 in pre-pubertal GHD children and to evaluate the effect of a dose increase on IGF-I and height velocity within a subset of the GHD children. In the ongoing Extension Study, subjects in the Phase 2a study on a VRS-317 dose of either 2.5 mg/kg semi-monthly or 5.0 mg/kg monthly were continued on the same dose for an additional 6 months. Subjects in the Phase 2a study on a VRS-317 dose of 1.15 mg/kg weekly (5 mg/kg/month) were switched to 3.5 mg/kg semi-monthly (7 mg/kg/month) upon their first visit after the completion of the Phase 2a study. Subjects enrolled in the Extension Study as they completed the six months of treatment in the Phase 2a study.

About Versartis, Inc. Versartis, Inc. is an endocrine-focused biopharmaceutical company initially developing VRS-317, a novel, long-acting form of recombinant human growth hormone for the treatment of growth hormone deficiency (GHD). VRS-317 is intended to reduce the burden of daily injection therapy by requiring significantly fewer injections, potentially improving compliance and, therefore, treatment outcomes. The Company completed the Phase 2a stage of a Phase 1b/2a trial evaluating weekly, semi-monthly and monthly dosing regimens of VRS-317 in children with GHD in June 2014 and began a global Phase 3 registration study, VELOCITY, in GHD children in January 2015.
