3 Auto Injector Device Profile Name Subcutaneous Testosterone Enanthate Auto injector (SCTE-AI) Dosing Once weekly, single use, fixed dose subcutaneous product Doses 1. 5 mg/.5 ml TE in oil solution mg/.5 ml TE in oil solution 3. 1 mg/.5 ml TE in oil solution Product Features Easy to use and store at room temperature Fine (27-gauge) needle allows for rapid subcutaneous delivery of sesame oil suspension Locking needle guard hides needle before, during, and after administration and reduces risk of needle stick injuries 3

4 STEADY: Objective and Endpoints Primary Objective Demonstrate efficacy of SCTE-AI administered subcutaneously once each week to adult males with hypogonadism Primary Endpoint Percentage of patients with average serum TT concentration (TT C avg168h ) over 7-day dosing interval within range (3-11 ng/dl) Secondary Endpoint Maximum serum TT C max distribution at Week 12 <15 ng/dl 85% < 5% >25 = % 44

8 Safety Overview Treatment was well tolerated Most frequent IP-related TEAEs were increased hematocrit, increased PSA, and mild-to-moderate injection-site bruising (<1% of injections) 3 (2.%) patients had TEAEs that led to study discontinuation 24 (16.%) patients had a TEAE related to study drug and leading to discontinuation Most frequent TEAEs that led to discontinuation were elevated PSA (13 events) and increased hematocrit (7 events) 3 SAEs (vertigo, depression, suicide) were reported but not considered drug related by investigators 8 8

9 Patient Compliance and Satisfaction Median treatment compliance was 1% 1,51 of 1,519 (99.4%) of observed injections were reported as painless Satisfaction with self-injections, ease-of-use, self-image, and injection site reactions increased from Baseline to Week 12 Overall improvement was observed across all Psychosexual Daily Questionnaire (PDQ) domains, including sexual desire, enjoyment, performance, mood and in erection quality from Baseline to Week

10 Efficacy STEADY Summary The majority of patients (92.7%) achieved mean TT Cavg168h within the defined range at Week 12 Overall, the mean Week 12 TT Cavg168h was ng/dl (ranging from ng/dl to ng/dl) No patients had TT maximal concentrations 15 ng/dl at Week 12, regardless of SCTE-AI dose TT concentrations <3 ng/dl were observed in less than 3% of patients in any SCTE-AI dose group 1 1
