CINV Highlights

•

SUSTOL®

(granisetron injection, extended release), is a long-acting, injectable

product for the prevention of chemotherapy-induced nausea and vomiting

(CINV)

–

1,341-patient,

randomized,

controlled,

Phase

study

demonstrated

activity

in acute and delayed onset CINV after moderately emetogenic

chemotherapy, and acute onset CINV after highly emetogenic chemotherapy

(HEC)

–

On-going 1000 patient study in patients receiving HEC is designed to obtain

“delayed

HEC”

indication;

injectable

5-HT

agent

currently

approved

for delayed HEC

•

HTX-019

is a proprietary intravenous (IV) formulation of aprepitant, an

receptor

antagonist

and

distinguished

from

the

only

receptor

antagonist presently approved in the U.S. in that it does not contain polysorbate

80, which may cause hypersensitivity reactions in some patients

–

Rapid development utilizing the 505(b)(2) registration pathway is anticipated

to achieve NDA submission in 1H2016

5-Day Profile: APF530 Pharmacokinetics

Granisetron is released rapidly following injection of APF530 and continues to be released

for 5-days, providing long-acting coverage for CINV

SUSTOL Pivotal Phase 3 Study

Overview

•

Randomized, controlled, multi-center study

•

1,341 patients in primary efficacy population

•

Two doses of APF530 (5 mg and 10 mg granisetron)

compared to the approved dose of Aloxi®

(results from 10

mg dose group presented)

•

Patients stratified by type of chemotherapy regimen:

moderately emetogenic (MEC) or highly emetogenic (HEC)

•

Primary end point compared complete response between

groups in both the acute (day 1) and delayed (days 2-5)

phase

–

Complete response defined as no emesis and no rescue medications

–

±15% margin used to establish non-inferiority

CINV FRANCHISE

COMMERCIAL OPPORTUNITY

Commercial Opportunity Summary

Market

•

Heron has the opportunity to establish a long-term, dominant position in a CINV

market targeting 3.6M units of IV 5HT-3 and NK-1 annually

•

The NK-1 market grew 10% YOY in 2013 with significant opportunity for

increased penetration into MEC regimens

Competitive

Landscape

•

New branded, injectable agents will be well-positioned to gain significant share

as current market leaders (Aloxi, EMEND) lose patent protection

•

SUSTOL positioned to be the only branded injectable 5HT3 on the market following Aloxi’s

patent expiry in 2015

•

HTX019 anticipated to be similarly positioned following EMEND’s patent expiry in 2019

Go-To-Market

Strategies

•

Differentiate SUSTOL and HTX019 clinically to drive uptake

•

SUSTOL targeted to be the first and only injectable 5HT3 indicated for the prevention of acute

and

delayed

CINV

both

MEC

and

HEC

•

HTX019 has potential to differentiate vs. IV EMEND based on polysorbate 80-free formulation

•

Leverage a highly synergistic CINV portfolio to maximize return on investment

•

~600 practices account for ~90% of both Aloxi and IV Emend use in clinic segment

•

SUSTOL-targeted practices are the highest users of IV EMEND

•

Highly leveraged cost effective commercial footprint

POST-OPERATIVE PAIN PROGRAM

Goals for Pain Program

•

Develop products that provide a clear advantage compared to

available therapies

•

Take advantage of the FDA’s current focus on reducing the use

of opiates

•

Main goals of therapy for our post-operative pain program

–

Significantly reduce:

•

pain intensity for 3-4 days post-operatively

•

opiate use

•

length of hospital stay

•

hospital readmissions due to pain

•

Target for product

–

Easy to use for a large variety of procedures

–

Does not require refrigeration or special handling
