Vicinium: Apparatus of Action 12
Vicinium: Analysis of High-Grade NMIBC • Float Blight - 2nd best accepted blight of genitourinary arrangement ‒ Ninth best accepted blight diagnosed accepted (~430,000 new patients/year)* ‒ In the U.S., float blight has the accomplished per accommodating analysis costs • Indirect costs of $184,762 to $461,907 per patient. • Non-muscle invasive float blight (NMIBC) is advised by urologists, accounts for 70-80% of all float cancers • Bacillus Calmette-Guerin (BCG) with or afterwards transurethral resection of the float bump (TURBT) is first-line analysis for high-grade NMIBC ‒ Aerial abortion ante in high-grade ache (50% aural 1 year, 90% percent aural 5 years) • Antecedent bazaar befalling is for high-grade NMIBC patients adverse to BCG • No above advances in 40 years *World Blight Research Fund (http://www.wcrf.org/int/cancer-facts-figures/worldwide-dataInternational) 13
Vicinium: Analysis of High-Grade NMIBC Expanded break - In accession to the antecedent BCG adverse market, we accept Vicinium may accept applications in the afterward added indications: • Retreatment: Patients who acknowledge to Vicinium and afterwards accept a recurrence, could potentially accept a added annular of Vicinium consecration and aliment analysis • Advancing aliment therapy: Patients who accept a CR and abide recurrence-free at 2- years, could potentially abide aliment analysis • Aggregate therapy: Vicinium could potentially be acclimated in aggregate with BCG in added line. • BCG has been in abbreviate supply. Though Sanofi is now aback in production, they accept appear they intend to stop accomplishment BCG in 2018. Hence, Vicinium could potentially be acclimated first-line, afterwards TURBT, for patients who abridgement admission to BCG. • Patients who are immuno-compromised are at aerial accident of broadcast BCG-disease. Vicinium could potentially be acclimated for such patients • For patients at aerial accident of progression (CIS and T1), Vicinium could potentially be acclimated in aggregate with BCG in aboriginal band 14

Assurance and Exploratory Ability • CIS citizenry Complete Acknowledgment (CR) amount at 3 months: • Low dosage (0.1 mg - <1.0mg): 1/6 (17%) • Aerial Dosage (≥ 10.0mg): 4/11 (36%) • Papillary patients: • 19/44 (43%) • No dosage attached toxicities (DLTs) reported. Able-bodied acceptable at these doses. • No best acceptable dosage (MTD) was reached. • Abandoned 2 capacity with detectible systemic levels (very abreast the LLQ). No analytic complications Adverse authentic as ceremony aural 2 years afterwards at atomic one abounding aeon of BGC. 5 of 64 patients were BCG antipathetic *Source: Kowalski et. al., Biologic Design, Development and Analysis 4: 313, 2010 15

Adverse Events: Phase 1 and 2 Trials • No cogent toxicity or tolerability issues ‒ About able-bodied acceptable ‒ No capacity clumsy to complete analysis • Phase 1 Balloon ‒ 31% of capacity accomplished an AE accompanying to analysis ‒ 98% of all AEs were Brand 1 or 2 ‒ Accident of AEs decreased with accretion dosage ‒ No treatment-related SAEs were appear • Phase 2 Balloon ‒ 65% of capacity had an AE accompanying to treatment, % of capacity with AEs agnate in both analysis accoutrements ‒ 6 capacity appear SAEs. None of the SAEs were bent to be accompanying to the abstraction drug. • AEs behindhand of abettor ‒ Renal and urinary disorders were the best accepted adverse contest • Hematuria, dysuria, pollakiuria, micturition urgency, urinary amplitude infections, nocturia, bender and float affliction and spasms ‒ The best common systemic adverse contest • Fatigue and Dizziness 18

Vicinium Abstraction in Float Blight (VISTA) • Afterward the advice provided by FDA, we commenced an open-label, non- randomized Phase 3 analytic balloon of Vicinium in capacity with BCG refractory/relapsed high-grade NMIBC in the United States and Canada in Q3 2015 • Targeted to accept 134 capacity (77 capacity with CIS) at over 65 Centers (CIS and/or Papillary Tumors) • Commenced Phase 3 analytic balloon • Primary endpoint: CR for CIS capacity • Secondary endpoints accommodate time to ache ceremony and accident chargeless adaptation Sample Admeasurement 134 Patients with BCG- Unresponsive High-Grade NMIBC Consecration Phase Weeks 1 – 6 Twice Account Dosing Weeks 7 – 12 Once Account Dosing Aliment Phase Up to Anniversary 104 Every Added Anniversary Dosing Capacity with no affirmation of high-grade ache 20
Response Evaluation • Anniversary 13 (Post-Induction Phase) and every 13 weeks • Evaluation includes cystoscopy and urine analysis • Biopsies (directed) appropriate if apprehensive lesions are begin on cystoscopy • Random biopsies may be appropriate if urine analysis apprehensive for aerial brand urothelial blight • There are no fractional responses for CIS patients 21
NMIBC – Recent contest • Sanofi BCG advertisement – November 17th, Sanofi affairs to stop bearing BCG in mid-2017 adage it hasn’t been able to restore abounding assembly at a Toronto accomplishment bulb that had contagion problems. • Relevance: No accepted appulse on Vicinium Phase 3 balloon about bound availability of aboriginal band BCG could accessible above bazaar • In November 2016 the FDA appear “BCG-Unresponsive NMIBC: Developing Drugs and Biologics for Analysis Advice for Industry” for comments. We accept this advice re-affirmed our Vicinium Phase 3 protocol. Key points: • Confirmed single-arm accessible characterization balloon with CR amount as the primary endpoint can accommodate primary affirmation of capability to abutment a business application. • Appropriate the abeyant for acceptable abounding approval instead of codicillary approval acute a acknowledging balloon column approval. • Heat Biologics – November 30th, Presented black top-line abstracts from a Phase II abstraction of its advance activity candidate, HS-410 for the analysis of NMIBC • Relevance: This follows Telesta’s analytic complete acknowledgment letter. Both were advancing allowed stimulatory access adjoin Eleven’s targeted analysis 22

Preclinical Appraisal with a Checkpoint Inhibitor • Immunodeficient myeloablated NOG mice engrafted with animal cartilage bottom axis cells. Mice built-in with contralateral EpCAM “ ” PDX tumors and aftereffect of Proxinium on injected tumors and uninjected tumors abandoned or in aggregate with a PD-1 inhibitor was assessed. • Proxinium resulted in decidedly bigger advance ascendancy of the injected bump than the checkpoint inhibitor alone. • The aggregate of Proxinium and the checkpoint inhibitor apparent bigger advance ascendancy of the uninjected bump than either abettor alone. This acknowledgment occurred in a time anatomy constant with the consecration of an allowed response. Injected Tumors Uninjected Tumors 33
Proxinium: Proposed Analytic Development Plan • The empiric responses in non-injected tumors during our analytic trials suggests that an anti-tumor allowed acknowledgment may be generated adjoin bump neoantigens appear from bump beef dead by Proxinium • Opdivo® and Keytruda® accept been accustomed for analysis of SCCHN. The abeyant for Proxinium to abet cross-priming and arbitrate allowed killing of non-targeted tumors suggests that a aggregate abstraction may be the best aisle advanced • We plan to admit a non-comparative balloon in SCCHN evaluating Proxinium in aggregate with a checkpoint inhibitor 34
