Lead product candidate, APF530, is long-acting, injectable

product for chemotherapy-induced nausea and vomiting (CINV)

Incorporates

widely

used

5-HT3

antagonist

granisetron

(Kytril

)

5-day delivery profile

Reduces both acute-

and delayed-onset CINV with single injection

market

leader

Aloxi

1,341-patient, randomized, controlled, Phase 3 study

APF530 targets a large market opportunity, with approximately

7 million doses of chemotherapy annually in US alone*

Recent competitive setbacks could enhance commercial uptake

Could be second, long-acting, injectable product on market

A.P. Pharma has the potential to leverage its Biochronomer™

drug delivery technology, its development capacity and

commercial expertise into other opportunities

Summary of Clinical Results

Bioerodible polymer technology releases granisetron to prevent CINV

over at least 5 days

Large, randomized, Phase 3 study conducted with APF530 showing

non-inferiority to Aloxi with the 10 mg of APF530

For both acute-

and delayed-onset CINV

With both moderately and highly emetogenic chemotherapy

APF530 was well-tolerated

Incidence of adverse events comparable to Aloxi

Injection site reactions where predominately mild

Good response rates were observed in difficult chemotherapy

regimens

Efficacy was maintained with reanalysis using ASCO 2011 guidelines

and through multiple cycles of chemotherapy

TQT study showed APF530 has no effect on QT; differentiated from

Zofran (most common dose restricted) and Anzemet (CINV claim

removed)

Regulatory Status

APF530 NDA Status

Submitted NDA in May 2009 under 505(b)(2) filing pathway

Received Complete Response Letter in March 2010

FDA raised major

issues in three main areas:

Dosing system

Chemistry, Manufacturing, and Controls (CMC)

Clinical/statistical

Resubmitted NDA in September 2012

Addressed issues raised in Complete Response Letter

Received Complete Response Letter March 2013 raising three

main issues:

CMC: correction of PAI issues and revision of one in-vitro release method

Requirement for Human Factors Validation Study with commercial product

Re-analysis of the existing Phase 3 study using the ASCO 2011 guidelines

for catagorization of MEC and HEC

July 2013

New Management Team is Addressing the CRL

Chemistry, Manufacturing, and Controls

Sites with PAI issues are being eliminated from the supply chain, with

work transferred to well established site with no PAI issues

Secondary benefit of consolidating manufacturing and release efforts:

substantial improvement in COGS

New in-vitro release method has been developed and being validated

Plan to produce three validation batches of finished product in advance of

re-filing to supply Human Factors Study

Human Factors Study

Will be conducted as soon as commercial material available

Re-analysis of Phase 3 using new ASCO 2011 Guidelines

Re-analysis complete

Complete dataset and programs ready to supply to FDA

Re-submission is now planned for 1Q2014

Commercial Opportunity

July

2013

Continuing Unmet Need in CINV

Need for long-acting antiemetic

therapies

Delayed CINV (days 2-5) remains particularly

challenging to manage

Significant portion of patients fail to respond

to Aloxi

Need for antiemetic therapies with

sustained efficacy

CINV risk increases over multiple

chemotherapy cycles

Available at: http://www.cancer.gov/cancertopics/pdq/supportivecare/nausea/HealthProfessional/page6#Section_183

“Despite the use of both first-generation

and

second-generation

5-HT

receptor

antagonists, the control of acute CINV, and

especially delayed nausea and vomiting,

suboptimal,

and

there

considerable

opportunity for improvement

with either

the addition or substitution of new agents in

current regimens.”

Addressing Debilitating Effects of CINV

July 2013

More than 7 million cycles of

chemotherapy administered each

year*

~27% are highly emetogenic

~46% are moderately emetogenic

Most chemotherapy patients will

undergo 4-15 cycles of

chemotherapy

5-HT3 antagonists are standard-

of-

care for CINV

Recommended in ASCO, NCCN

and ONS guidelines

NK-1 antagonists are only indicated

in combination with 5-HT3

antagonists

An Injectable 5-HT3 antagonist is

co-administered with more than

90% of MEC and HEC regimens

If initial regimen is non-effective,

drugs are added or changed to

address CINV in subsequent cycles

*TDR August 2006

5-HT3 Antagonists Have Made a Substantial Impact

metoclopramide

Summary

July 2013

CINV market is a large commercial opportunity, with approximately 7

million doses of chemotherapy per year in US

APF530 demonstrated non-inferiority to the market share leader Aloxi,

with 2012 annual sales of $440M

and ~50% unit market share

APF530 product profile

5-day release PK profile

Good response in difficult chemotherapy regimens

Efficacy through multiple cycles of chemotherapy

Clean QT results

Current market dynamics are stale with minimal investment providing

opportunities to become the market leader

Competitive landscape creates opportunity with the removal of Anzemet

and Zofran 32mg

Greater

A.P. Pharma Product Lifecycle Considerations

APF530 covered by multiple patents

2 patents covering combination of polymer, excipients and drug expire in

2021

3 patents covering APF530 expire in 2024

Polymer-based injectable products are difficult to copy

independent of IP

ANDA FDA requirements for injectable products

Must have same inactive ingredients in the same concentration as

the

reference listed drug

Polymers are complex mixtures of varying-length molecules, making

characterization for “sameness”

very challenging
