Forward Looking Language Statement

This presentation includes forward-looking statements regarding Isis Pharmaceuticals’ financial

position and outlook, Isis’ business, and the therapeutic and commercial potential of Isis’ technologies

and products in development. Any statement describing Isis’ goals, expectations, financial or other

projections, intentions or beliefs is a forward-looking statement and should be considered an at-risk

statement. Such statements are subject to certain risks and uncertainties, particularly those inherent

in the process of discovering, developing and commercializing drugs that are safe and effective for

use as human therapeutics, and in the endeavor of building a business around such drugs. Isis’

forward-looking statements also involve assumptions that, if they never materialize or prove correct,

could cause its results to differ materially from those expressed or implied by such forward-looking

statements. Although Isis’ forward-looking statements reflect the good faith judgment of its

management, these statements are based only on facts and factors currently known by Isis. As a

result, you are cautioned not to rely on these forward-looking statements. These and other risks

concerning Isis’ programs are described in additional detail in Isis’ annual report on Form 10-K for the

year ended December 31, 2013, and its most recent quarterly report on Form 10-Q, which are on file

with the SEC. Copies of these and other documents are available from the Company.

Results: Additional Measurements of Motor

Function Are Consistent and Encouraging

Results of Six Minute Walk Test (6MWT) and Upper Limb

Module (ULM) test consistent with increases observed in

Hammersmith Functional Motor Scale–Expanded

Mean increase of 22.7 meters (SEM ±12.3) observed at 9 months

in 6MWT in 9 ambulatory patients (mean baseline 230.8 m,

SEM ±31.4)

6MWT measures the distance an ambulatory SMA patient is able to walk over a

total of six minutes on a hard, flat surface

Mean increase of 2.3 points (SEM ±0.9) observed at 9 months in

the ULM test in 10 nonambulatory patients (mean baseline 10.5,

SEM ±1.0)

ULM Test used for SMA patients who were nonambulatory, in which a 9 item scale

is scored as 0, 1 or 2 per item (max score 18)

ISIS-SMNRx Lessons Learned Supporting Phase 3

Design and Conduct

Data support selection of the 12mg dose for pivotal studies

Long half-life of ISIS-SMNRx in CNS supports infrequent dosing

Two to three month loading dose schedule followed by infrequent

maintenance administration

In infants with SMA, data support time to death/permanent ventilation

as primary endpoint with motor function (CHOP INTEND, motor

milestones) as secondary endpoints

Regulatory agencies agreement

In children with SMA, data support change from baseline in

Hammersmith motor function scale as the primary endpoint in pivotal

study

Glucagon Receptor (GCGR) A Validated Target for the Treatment of Diabetes

Glucagon is a hormone that opposes the action of

insulin

Increased glucagon action leads to increased glucose

production by the liver

Glucagon receptor reduction in animal models

produces dramatic reductions in glucose even in the

most severe models

Several small molecule inhibitors have reduced

glucose but have been associated with off-target side

effects

Reasons to Develop ISIS-GCGRRx:

The Potential to Be Best in Class

Likely to have greater glucose reduction than small molecules by directly

reducing production of the receptor

Likely not to have side effects associated with some small molecules

Increases in LDL-cholesterol

Increases in triglycerides

Increases in blood pressure

Increases in body weight

Likely to have a broader separation of doses that produce glucose

reduction from those that produce target-related ALT increases

Optimal balance between glucose reduction and ALT increases achievable

Robust and long lasting effect on glucose lowering provides opportunity

to balance glucose control with liver safety

Likely to be dual acting and potential to preserve pancreatic function

To be developed for treatment of advanced diabetes 90

91

Dual sites of action

Reduces hepatic glucagon action, which attenuates hyperglycemia

Increases GLP-1, which improves insulin secretion and leads to pancreatic

regeneration (potential for disease modification)

Robust effects in very insulin resistant animals

No fatty liver or increase in hepatic glycogen; no change in plasma lactate

levels, liver ALTs or LDL cholesterol levels

No hypoglycemia up to 24h fast in rodents and 16h in monkeys

No effect on recovery from insulin-induced hypoglycemia in rodents

No alpha cell hyperplasia or pancreatic tumors up to 6–month treatment in

monkeys

Tissue-specific Inhibition of the Glucocorticoid Receptor A Unique Therapeutic Target for the Treatment of Diabetes

Excessive glucocorticoids (GC) action in liver and fat is

involved in obesity, insulin resistance and glucose

intolerance

Glucocorticoid receptor (GCCR) is an intracellular

receptor that mediates the action of GCs

Attenuation of GC action through its receptor is

a very attractive therapeutic approach for type 2

diabetes and disorders related to excessive

and chronic steroid action (e.g., Cushing’s disease)

Efficacy exceeds that observed with small molecule

inhibitors of 11bHSD1

ISIS-GCCRRx has the potential to be best in class by taking

advantage of distribution of antisense drugs

mechanism of action currently in development

ISIS-PTP1BRx selectively targets protein tyrosine phosphatase 1B

ISIS-FXIRx Preclinical Data Summary Significant Antithrombotic Activity Without Bleeding

Specifically reduces Factor XI levels in several animal species

Even with Factor XI levels reduced by over 90%

No spontaneous bleeding

No change in other coagulation factors

Antithrombotic activity comparable to that of currently available

anticoagulants, but less bleeding demonstrated in multiple

animal models

Potential for safer therapy as single agent or as combination

therapy with antiplatelet drugs

ISIS-FXIRx: Dose-dependent Reduction of VTEs

with a Low Incidence of Bleeding Data Cutoff May 7, 2014

With 200 mg ISIS-FXIRx, rate of venous

thromboembolism (VTE) is similar to enoxaparin

200 mg cohort expanded to further enhance comparison to

enoxaparin

With 300 mg ISIS-FXIRx, rate of VTE is 7-fold lower

than enoxaparin (p<0.0001)

Patients treated with enoxaparin and ISIS-FXIRx

experienced a very low rate of bleeding

ISIS-FXIRx-treated patients experienced numerically fewer

bleeding events than with enoxaparin

ISIS-FXIRx: Conclusions from Phase 2 Study

127

■ Enoxaparin efficacy and bleeding rates were within expected

ranges in this patient population

■ Findings provide proof-of-principle that ISIS-FXIRx is an effective

and safe anticoagulant

■ ISIS-FXIRX decreases VTE in a dose-dependent fashion

■ Rate of VTE in 300 mg cohort is substantially lower than published

reports of Factor Xa or thrombin inhibitors in this therapeutic

setting

Bleeding rates were very low in the enoxaparin group and

numerically lower in the ISIS-FXIRx-treated patients

■ Only Factor XI inhibitor in clinical studies

Pathway validated by Isis

ISIS-PKKRx for Hereditary Angioedema Approximately 15-20K Patients in US and EU

Hereditary Angioedema (HAE) is a potentially life threatening immune

disease

Characterized by low levels or dysfunction of the C1 inhibitor protein

HAE patients have attacks that are often disabling and sometimes fatal, and

characterized by rapid and painful swelling in the hands, feet, limbs, face,

abdomen, larynx and trachea

ISIS-PKKRx reduces Prekallikrein (PKK), a clinically validated target

PKK disrupts the kinin contact cascade that triggers HAE attacks

The role of kinins in HAE has been established by acute treatments used after an

attack has already occurred

Current prophylactic treatments (e.g., androgens, C-1 inhibitor

replacement) are either inadequate or very difficult to use

Unmet need: Up to 80% of patients are not using IV prophylaxis and would use a

s.c. prophylactic if effective and available

ISIS-PKKRx: potential best-in-class treatment for HAE

Targeted, mechanism-based therapy that could prevent attacks by altering the cause

of the disease

Antisense reduction in PKK prevented or ameliorated tissue swelling in animal

models of HAE

Convenient, at-home self-administered subcutaneous injections

Infrequent, low-volume injections

Improved tolerability and safety compared to existing prophylactic treatments

Rapid path to proof-of-concept study

Phase 1 study in healthy volunteers has already begun

Planned clinical study in HAE patients in 2H 2014

DM1 Disease Overview RNA-caused Disease Uniquely Suited to Antisense Therapy

Autosomal dominant genetic disease that causes

Severe muscle problems that include weakness (myopathy), trouble relaxing muscles

(myotonia) and muscle wasting

Affects other body functions, including the heart and gastrointestinal system

DM1 is caused by production of toxic RNA in the cell nucleus

Caused by expanded CUG repeat in 3’-UTR of Dystrophia Myotonica-Protein Kinase

(DMPK)

Repeat length ranges from 50 to 3000 repeats & correlates to disease severity

DM1 often affects an entire family: ‘anticipation’ can occur with each

generation getting a more severe form of the disease due to expansion of

repeat

Affects 40,000 patients in US: 150,000 patients in US, EU and Japan
