ARIAD PRESENTS LONG-TERM PHASE 1/2 TRIAL FOLLOW UP ON

INVESTIGATIONAL DRUG BRIGATINIB WITH MEDIAN TIME ON

TREATMENT OF 17 MONTHS IN ALK+ NSCLC PATIENTS

~ Longest Time on Treatment Now More Than 3.5 Years

for Patients with ALK+ Non-Small Cell Lung Cancer

~ Data from Phase 1/2 Clinical Trial Presented at 2016 ASCO Meeting

Chicago, IL and Cambridge, MA – June 4, 2016 – ARIAD Pharmaceuticals, Inc. (NASDAQ: ARIA) today announced updated clinical data on its investigational tyrosine kinase inhibitor (TKI), brigatinib, in patients with anaplastic lymphoma kinase-positive (ALK+) advanced non-small cell lung cancer (NSCLC) from an ongoing Phase 1/2 trial. The current results include more mature efficacy and safety data for brigatinib, including updated response rates and median duration of response in ALK+ NSCLC patients.

The updated Phase 1/2 results are being presented today at the 2016 American Society of Clinical Oncology (ASCO) annual meeting in Chicago.

Phase 1/2 Study

The data presented at ASCO include safety analyses on all patients in the trial (n=137) and efficacy analyses on all patients with ALK+ NSCLC (n=79). Of the 79 ALK+ NSCLC patients, all but eight had failed prior crizotinib. The presentation is based on patient data as of November 2015 with a median time on treatment for ALK+ NSCLC patients of 17.0 months (range, 0.03 – 44.4 months, ongoing). Patient enrollment in the trial is complete, with the last patient enrolled in July 2014.

“The long-term follow up on this clinical trial of brigatinib shows substantial anti-tumor activity with an objective response rate of approximately 72 percent in crizotinib-resistant ALK-positive NSCLC patients,” stated D. Ross Camidge, M.D., Ph.D., director of thoracic oncology at the Colorado University Cancer Center. “The median progression-free survival in this post-crizotinib patient group exceeds one-year and has not yet been reached in patients not previously treated with crizotinib. Importantly, no new safety signals have emerged at this later time of follow up.”

Key data from the study include:

Anti-tumor Activity of Brigatinib in ALK+ NSCLC Patients

• Of the 71 ALK+ NSCLC patients with prior crizotinib therapy, 51 (72%) demonstrated an objective response to brigatinib. Forty-four responses were confirmed (62%).

^¡  Of the 25 patients treated at the 180 mg dose regimen that included a seven-day lead-in dose of 90 mg, 20 (80%) demonstrated an objective response, of which 19 (76%) were confirmed.

• Of the eight crizotinib-naive ALK+ NSCLC patients treated with brigatinib, all demonstrated an objective response (100%), including three complete responses (CR). All responses were confirmed.

• The “waterfall plot” analysis demonstrated tumor shrinkage in nearly all ALK+ NSCLC patients, with 21 patients experiencing 100 percent shrinkage of the target lesions.

• The median duration of response in confirmed responders was 14.5 months in ALK+ NSCLC patients treated with prior crizotinib therapy and was not yet reached in ALK+ NSCLC patients who were crizotinib-naive.

• Median progression-free survival (PFS) was 12.9 months in ALK+ NSCLC patients with prior crizotinib therapy and was not yet reached in ALK+ NSCLC patients who were crizotinib-naive.

• Overall survival (OS) at one year was 77 percent in patients who received prior crizotinib (projected 2-year OS was 63%) and 100 percent in patients who were crizotinib-naive (projected 2-year OS was 100%).

An evaluation of the efficacy of brigatinib in ALK+ NSCLC patients with intracranial CNS metastases at baseline was also included in the ASCO presentation. In an independent central review of brain magnetic resonance imaging (MRI) scans, 46 ALK+ NSCLC patients were evaluable for intracranial response, including 15 who had measurable intracranial

2

CNS metastases at baseline, and 31 patients who had only non-measurable intracranial CNS metastases.

^¡  10 of 15 (67%) patients with measurable intracranial CNS metastases had an intracranial objective response, and 13 of 31 (42%) with only non-measurable intracranial CNS metastases had complete disappearance of intracranial lesions.

^¡  Median intracranial PFS for ALK+ NSCLC patients with intracranial CNS metastases at baseline was 15.6 months. Median duration of intracranial response in confirmed responders was 11.4 months.

Safety and Tolerability – All Patients Enrolled

• The most common treatment-emergent adverse events (AEs; ³ 30%), regardless of relationship to treatment, in all patients were nausea (51%), fatigue (42%), diarrhea (41%), headache (34%), and cough (33%).

• Treatment-emergent AEs, regardless of relationship to treatment, grade 3 or higher, occurring in ³4% patients were increased lipase (9%), dyspnea (7%), hypertension (5%), increased amylase (4%), and fatigue (4%)

• Serious treatment-emergent AEs, regardless of relationship to treatment, occurring in three or more patients were dyspnea (7%), pneumonia (7%), hypoxia (5%), pulmonary embolism (3%), malignant pericardial effusion (2%), and pneumonitis (2%).

• A subset of pulmonary AEs (including dyspnea, hypoxia, pneumonia and/or pneumonitis) was observed to occur within 7 days of treatment initiation or treatment re-initiation following a prolonged dose interruption. Most events occurred within 48 hours of dosing and were generally managed with dose interruption or discontinuation.

^¡  Rates of these AEs were numerically lower with lower starting doses (11/137 [8%], overall)

^¡  6/44 (14%) in patients started at 180 mg qd

^¡  1/50 (2%) in patients started at 90 mg qd

^¡  Among 32 patients treated with 90 mg qd for 7 days followed by 180 mg qd, no such events were reported after dose escalation

• Administration of brigatinib at 180 mg with a 7-day lead-in at 90 mg appears to not be associated with an increased risk of additional early pulmonary AEs, when compared with continuous administration of brigatinib at 90 mg.

ARIAD PRESENTS DATA FROM MUTATIONAL PROFILING IN

CRIZOTINIB-RESISTANT PATIENTS TREATED WITH INVESTIGATIONAL

MEDICINE BRIGATINIB SHOWING SIMILAR RESPONSE RATES IN

PATIENTS WITH AND WITHOUT SECONDARY ALK MUTATIONS

~ Brigatinib Achieves Confirmed Response in Patient with G1202R Mutation that Emerges

Following Treatment with Current Approved Therapies

Chicago, IL and Cambridge, MA – June 4, 2016 – ARIAD Pharmaceuticals, Inc. (NASDAQ: ARIA) today announced clinical data from an analysis aimed at characterizing the activity of its investigational tyrosine kinase inhibitor (TKI), brigatinib, in patients with anaplastic lymphoma kinase positive (ALK+) advanced non-small cell lung cancer (NSCLC) who have progressed on crizotinib. The analysis was based on ALK mutation status as determined by next-generation sequencing (NGS) of tumor tissue collected from the ongoing Phase 1/2 and ALTA clinical trials.

Data from this analysis showed that brigatinib yields confirmed responses in patients with multiple different secondary ALK mutations, including one G1202R case. There are no currently approved ALK treatments that have demonstrated activity against the G1202R mutation.

These data are being presented today at the 2016 American Society of Clinical Oncology (ASCO) annual meeting in Chicago.

Study Methods

Requirements for the Phase 1/2 and ALTA trials of brigatinib included that tumor tissue be collected at patient screening after failure on crizotinib therapy and prior to brigatinib treatment. An optional post-baseline tumor biopsy also was requested following disease progression on brigatinib. Tumor samples were analyzed using a NGS (next-generation sequencing) platform that examined the entire coding sequence of 315 cancer-related genes plus introns from 28 genes often rearranged or altered in cancer. This analysis focuses on the relationship between brigatinib clinical activity and ALK mutation status at baseline and after disease progression on brigatinib therapy.

A total of 32 baseline tumor samples from the clinical trials of brigatinib were evaluable using NGS, and a total of six post-baseline samples following disease progression on brigatinib were evaluable by NGS.

Study Results

• Of the 32 patients with baseline NGS data, 22 (69%) achieved a confirmed objective response on brigatinib.

• Of the 9 patients with secondary ALK mutations at baseline, 7 (78%) achieved a confirmed objective response on brigatinib.

• Of the 23 patients without secondary ALK mutations at baseline, 15 (65%) achieved a confirmed objective response rate (ORR) on brigatinib.

• Of the 6 patients with evaluable tissue samples collected after progression on brigatinib therapy, 5 (83%) were determined to have detectable secondary mutations in the ALK kinase domain. Three out of five of these patients had complex mutation patterns, following responses lasting 5.4, 7.4 and 28.5 months. Two out of five had single secondary ALK kinase domain mutations detected, following responses lasting 10.9 and 11 months.

• Of the one patient with a secondary G1202R mutation, the patient achieved a confirmed response on brigatinib and the response is on-going.

“It is encouraging that responses to brigatinib were observed in patients with crizotinib resistant ALK+ lung cancer with and without the presence of ALK resistance mutations. This is consistent with preclinical studies showing brigatinib to be a potent pan-inhibitor of all known ALK secondary resistance mutants,” stated Scott N. Gettinger, M.D., associate professor of medicine at Yale Cancer Center.

FOR IMMEDIATE RELEASE

ARIAD’S INVESTIGATIONAL MEDICINE BRIGATINIB DEMONSTRATES 54

PERCENT CONFIRMED OBJECTIVE RESPONSE RATE AND 12.9-MONTH

MEDIAN PROGRESSION-FREE SURVIVAL IN ALTA STUDY

~ 67 Percent Confirmed Intracranial Objective Response Rate

in Patients with Measurable Brain Metastases

~ Data from Pivotal Study in Refractory ALK Positive

Non-Small Cell Lung Cancer Patients

~ Investor and Analyst Webcast to be Held at the 2016 ASCO Meeting Today at 7 a.m. CT

Cambridge, MA, June 6, 2016 – ARIAD Pharmaceuticals, Inc. (NASDAQ: ARIA) today announced updated clinical data on brigatinib, its investigational anaplastic lymphoma kinase (ALK) inhibitor, from the pivotal ALTA trial in patients who had experienced disease progression on crizotinib therapy. The data show that, of patients on the 180 mg regimen (Arm B) with a median follow-up of 8.3 months, 54 percent achieved a confirmed objective response, the trial’s primary endpoint. In this arm, the median progression free survival (PFS) exceeded one year (12.9 months) in this post-crizotinib setting. Additionally, a 67 percent confirmed intracranial objective response rate (ORR) was achieved in patients with measurable brain metastases. These data will be presented today, for the first time, at the Annual Meeting of the American Society of Clinical Oncology (ASCO), reflecting an additional 12 weeks of patient follow up and new data on central nervous system (CNS) activity compared to the abstract released last month.

“Most patients with ALK-positive non-small cell lung cancer who are treated with crizotinib eventually experience disease progression, often due to acquired ALK resistance mutations or metastases in the central nervous system,” said presenting author Dong-Wan Kim, M.D., Ph.D., head of the Cancer Clinical Trials Center at the Seoul National University Hospital in South Korea. “For these patients, we are very excited by the brigatinib ALTA trial data, which showed compelling efficacy and safety data, including complete responses and activity in the CNS.”

The ALTA trial

The primary endpoint of the ALTA (ALK in Lung Cancer Trial of AP26113) trial is investigator-assessed confirmed objective response rate (ORR) as measured by the

2

Response Evaluation Criteria in Solid Tumors (RECIST). Key secondary endpoints include progression free survival (PFS), confirmed ORR assessed by an independent review committee (IRC), CNS response (IRC-assessed intracranial ORR and PFS), overall survival, safety and tolerability. Brigatinib was granted the U.S. Food and Drug Administration (FDA) Orphan Drug designation for ALK+ non-small cell lung cancer (NSCLC) and the FDA Breakthrough Therapy designation for the treatment of patients with ALK+ non-small cell lung cancer (NSCLC) that is resistant to crizotinib.

The trial enrolled 222 patients with ALK+ NSCLC who had been treated with and experienced disease progression on crizotinib. Patients were randomized one-to-one to receive either 90 mg of brigatinib once per day (QD) (Arm A), or 180 mg QD with a seven day lead-in at 90 mg QD (Arm B).

In addition, patients were stratified by the presence of brain metastases at baseline and best response to prior crizotinib.

Key Data from the ALTA Trial

Brigatinib Efficacy and Safety in ALK+ NSCLC Patients:

Data as of February 29, 2016

• A total of 222 patients with ALK+ NSCLC treated with prior crizotinib therapy were randomized in the study (110 patients in Arm B at the 180 mg dose level with 7-day lead-in at 90 mg and 112 patients in Arm A at the 90 mg dose level). The last patient enrolled in the study in September 2015.

• The median follow-up was 8.3 months in Arm B (range 0.1–20.2) and 7.8 months in Arm A (range 0.1–16.7).

• Investigator-assessed confirmed ORR in Arm B was 54 percent, including four complete responses. Confirmed ORR in Arm A was 45 percent, including one complete response.

• Responses in Arm B included a confirmed partial response in a patient with the ALK kinase domain G1202R mutation at baseline, which is associated with resistance to all approved tyrosine kinase inhibitors (TKIs).

• Median PFS was 12.9 months and 9.2 months in Arm B and Arm A, respectively. Probability of overall survival (OS) at 1-year was 80 percent and 71 percent in Arm B and Arm A, respectively.

• An evaluation of the efficacy of brigatinib in ALK+ NSCLC patients with intracranial CNS metastases at baseline was also included in the ASCO presentation.

3

^¡  In an independent central review of brain magnetic resonance imaging (MRI) scans, 18 patients in Arm B and 25 patients in Arm A were identified as having measurable CNS metastases at baseline.

^¡  Among patients with measurable CNS metastases at baseline, the IRC-assessed confirmed intracranial ORR was 67 percent (12/18) in Arm B and 36 percent (9/25) in Arm A; among the subset of patients with measurable, active brain metastases, confirmed intracranial ORR was 73 percent (11/15) in Arm B and 36 percent (7/19) in Arm A. Measurable, active brain metastases are defined as having had no prior radiotherapy or progression following radiotherapy.

^¡  Median intracranial PFS for patients with intracranial CNS metastases at baseline was not yet reached in Arm B and was 15.6 months in Arm A.

• The most common treatment-emergent adverse events (TEAEs; ³ 25% of all patients, [Arm B/A]), regardless of relationship to treatment, were nausea (40%/33%), diarrhea (38%/19%), cough (34%/18%), and headache (27%/28%).

• TEAEs, ³ grade 3, occurring in ³ 5 percent of all patients (Arm B/A), were increased blood creatine phosphokinase (9%/3%) and hypertension (6%/6%).

• A subset of pulmonary adverse events with early onset (median: Day 2; range: Day 1-9) occurred in 6 percent of all patients (³ grade 3 in 3% of patients); no such events with early onset occurred after dose escalation to 180 mg QD in Arm B.

• Discontinuations and dose reductions due to AEs (Arm B/A) were 8 percent/3 percent and 20 percent/7 percent, respectively. Discontinuations due to progressive disease (Arm B/A) were 17 percent and 30 percent.

“The ALTA trial data support our planned NDA submission with a recommendation for dosing with 180 mg once daily following a seven-day lead-in at 90 mg. We are on track for submission in the third quarter,” stated Timothy P. Clackson, Ph.D., president of research and development and chief scientific officer at ARIAD. “We believe brigatinib’s antitumor activity both on disease in the lungs and in the central nervous system, safety profile, and once-daily dosing regimen taken with or without food, provide the potential for brigatinib to be an important new therapeutic option for the crizotinib-resistant patient population.”
