"Opioid-induced constipation represents a long-lasting and potentially debilitating side effect of opioid therapy for millions of patients suffering from chronic pain," commented Joseph C. Papa, Chief Executive Officer of Valeant. "We believe Oral RELISTOR represents a new alternative treatment for OIC, and we look forward to introducing the more convenient oral formulation as soon as practicable."

"We are delighted that this milestone for RELISTOR has been achieved, and that patients suffering from OIC will have this new treatment option," said Mark Baker, Chief Executive Officer of Progenics. "We expect the market to be receptive to a more convenient oral tablet formulation of RELISTOR’s well-established subcutaneous preparation. We would like to thank, in particular, Dr. Tage Ramakrishna and Dr. Robert Israel of Valeant for their work over many years in the clinical development of RELISTOR."

"RELISTOR has a unique mechanism of action that binds to mu-opioid receptors without impacting the opioid-mediated analgesic effects on the central nervous system," said Richard L. Rauck, MD, Medical Director, Center for Clinical Research, President, Carolinas Pain Institute, President of the Sceptor Pain Foundation of which he is a founding member, and Immediate Past President of the World Institute of Pain. "This represents a true breakthrough in the treatment of OIC, and addresses a large and growing need in the field of pain management."

Today, the FDA approved RELISTOR Tablets (450 mg once daily) for the treatment of OIC in adults with chronic non-cancer pain. Previously, RELISTOR Subcutaneous Injection (12 mg and 8 mg) was approved in 2008 for the treatment of OIC in adults with advanced illness who are receiving palliative care and in 2014 for the treatment of OIC in adults with chronic non-cancer pain.

About the Phase 3 Clinical Trial of Oral RELISTOR for OIC in Chronic Non-Cancer Pain (NCP)

A randomized, double-blind, Phase 3 trial was conducted to evaluate once-daily dosing of 450 mg (n=200) methylnaltrexone (MNTX) tablets compared to placebo (n=201) in adults with chronic NCP. In the 450 mg treatment arm, MNTX tablets demonstrated statistically significant improvements in rescue-free bowel movement (RFBM) within 4 hours of administration over 28 days of dosing when compared to placebo treatment, achieving the primary endpoint. The 450 mg treatment group also achieved statistical significance for the first key secondary efficacy endpoint where a higher percentage of responders (i.e., had ≥3 RFBMs/week, with an increase of ≥1 RFBM/week from baseline for at least 3 of the 4 weeks) was observed with MNTX treatment as compared to placebo. Overall, efficacy of oral methylnaltrexone in this study was comparable to that reported in clinical studies of subcutaneous methylnaltrexone in subjects with chronic, non-cancer pain. The overall observed safety profile seen in patients treated with oral methylnaltrexone was comparable to placebo in this study.

Important Safety Information about RELISTOR

RELISTOR (methylnaltrexone bromide) Tablets is contraindicated in patients with known or suspected gastrointestinal obstruction and patients at increased risk of recurrent obstruction, due to the potential for gastrointestinal perforation.

Cases of gastrointestinal perforation have been reported in adult patients with OIC and advanced illness with conditions that may be associated with localized or diffuse reduction of structural integrity in the wall of the gastrointestinal tract (e.g., peptic ulcer disease, Ogilvie’s syndrome, diverticular disease, infiltrative gastrointestinal tract malignancies or peritoneal metastases). Take into account the overall risk-benefit profile when using RELISTOR in patients with these conditions or other conditions which might result in impaired integrity of the gastrointestinal tract wall (e.g., Crohn’s disease). Monitor for the development of severe, persistent, or worsening abdominal pain; discontinue RELISTOR in patients who develop this symptom.

If severe or persistent diarrhea occurs during treatment, advise patients to discontinue therapy with RELISTOR and consult their healthcare provider.

Symptoms consistent with opioid withdrawal, including hyperhidrosis, chills, diarrhea, abdominal pain, anxiety, and yawning have occurred in patients treated with RELISTOR.

Patients having disruptions to the blood-brain barrier may be at increased risk for opioid withdrawal and/or reduced analgesia. Take into account the overall risk-benefit profile when using RELISTOR in such patients. Monitor for adequacy of analgesia and symptoms of opioid withdrawal in such patients.

Avoid concomitant use of RELISTOR with other opioid antagonists because of the potential for additive effects of opioid receptor antagonism and increased risk of opioid withdrawal.

The most common adverse reactions (≥ 12%) in adult patients with opioid-induced constipation and chronic non-cancer pain receiving RELISTOR tablets were abdominal pain, diarrhea, headaches, abdominal distention, hyperhidrosis, anxiety, muscle spasms, rhinorrhea, and chills. Adverse reactions of abdominal pain, diarrhea, hyperhidrosis, anxiety, rhinorrhea, and chills may reflect symptoms of opioid withdrawal.

In preclinical testing, ARQ 531 demonstrated biochemical inhibition of both wild type and C481S-mutant BTK at sub-nanomolar levels and potent cellular inhibition in C481S-mutant BTK cells that are resistant to ibrutinib. This molecule also exhibits a distinct kinase selectivity profile with inhibitory activity against several key oncogenic drivers related to ibrutinib resistance. It is currently estimated that about 10% of patients treated with ibrutinib develop resistance with over 80% presenting the C481S mutation. This incidence rate is expected to increase.

Additionally, the compound potently suppresses cell proliferation of hematological malignancies in vitro, with B-cell receptor signaling inhibition. ARQ 531 also demonstrates strong in vivo target and pathway inhibition of phospho-BTK with potent and durable growth suppression.

"We are beginning to see increasing resistance to ibrutinib which is creating the need for a BTK inhibitor, like ARQ 531, that targets the C481S mutation," said Dr. Brian Schwartz, Head of Research and Development and Chief Medical Officer at ArQule. "The preclinical profile of ARQ 531 as a potent and reversible inhibitor of wild type and mutant BTK presents the potential for a first-in-class and best-in-class molecule. We are working toward completing GLP toxicology studies and filing an IND in early 2017."

About BTK and ARQ 531

ARQ 531 is an investigational, orally bioavailable, potent and reversible Bruton’s tyrosine kinase (BTK) inhibitor. Biochemical and cellular studies have shown that ARQ 531 inhibits both the wild type and C481S-mutant forms of BTK. The C481S mutation is a known emerging resistance mechanism for first generation irreversible BTK inhibitors. ARQ 531 has high oral bioavailability as well as good ADME, pharmacokinetic and metabolic properties. The company plans to file an IND for ARQ 531 in early 2017. BTK is a therapeutic target that has been clinically proven to inhibit B-cell receptor signaling in blood cancers.

On July 18, 2016 Roche (SIX: RO, ROG; OTCQX: RHHBY) reported that the phase III GOYA study evaluating Gazyva/Gazyvaro (obinutuzumab) plus CHOP chemotherapy (G-CHOP) in people with previously untreated diffuse large B-cell lymphoma (DLBCL) did not meet its primary endpoint of significantly reducing the risk of disease worsening or death (progression-free survival; PFS) compared to MabThera/Rituxan (rituximab) plus CHOP chemotherapy (R-CHOP) (Press release, Hoffmann-La Roche , JUL 18, 2016,

Adverse events with Gazyva/Gazyvaro and MabThera/Rituxan were consistent with those seen in previous clinical trials when each was combined with various chemotherapies. Data from the GOYA study will be presented at an upcoming medical meeting.

"Two previous studies showed Gazyva/Gazyvaro helped people with previously untreated follicular lymphoma or chronic lymphocytic leukaemia live longer without their disease worsening compared to MabThera/Rituxan, when each was combined with chemotherapy. We were hopeful we could show a similar result for people with diffuse large B-cell lymphoma and once again improve on the standard of care," said Sandra Horning, MD, Chief Medical Officer and Head of Global Product Development. "We will continue to analyse the GOYA data to better understand the results, and to study other investigational treatments in this disease with the goal of further helping these patients."

About the GOYA study
GOYA (NCT01287741) is a global phase III open-label, multi-centre, randomised two-arm study examining the efficacy and safety of the combination of Gazyva/Gazyvaro plus CHOP chemotherapy (G-CHOP) compared to MabThera/Rituxan plus CHOP chemotherapy (R-CHOP). GOYA included 1,418 previously untreated patients with CD20-positive DLBCL. The primary endpoint of the study is investigator-assessed PFS, with secondary endpoints including PFS assessed by independent review committee (IRC), response rate (overall response, ORR; and complete response, CR), overall survival (OS), disease free survival (DFS) and safety profile. The GOYA study is being conducted in cooperation with the Fondazione Italiana Linfomi (FIL, Italy).

About Gazyva/Gazyvaro (obinutuzumab)
Gazyva/Gazyvaro is an engineered monoclonal antibody designed to attach to CD20, a protein expressed on certain B cells, but not on stem cells or plasma cells. Gazyva/Gazyvaro is designed to attack and destroy targeted B-cells both directly and together with the body’s immune system.
Gazyva/Gazyvaro is currently approved in more than 70 countries in combination with chlorambucil, for people with previously untreated chronic lymphocytic leukaemia. The approvals were based on the CLL11 study, showing significant improvements with Gazyva/Gazyvaro plus chlorambucil across multiple clinical endpoints, including PFS, overall response rate (ORR), complete response rate (CR), and minimal residual disease (MRD) when compared head-to-head with MabThera/Rituxan plus chlorambucil.
In February 2016, Gazyva was approved by the US Food and Drug Administration in combination with bendamustine followed by Gazyva alone for people with follicular lymphoma who did not respond to a Rituxan-containing regimen, or whose follicular lymphoma returned after such treatment. In June 2016, Gazyvaro was approved by the European Commission in combination with bendamustine followed by Gazyvaro maintenance in people with follicular lymphoma who did not respond or who progressed during or up to six months after treatment with MabThera or a MabThera-containing regimen. Both approvals were based on the phase III GADOLIN study, showing a significant improvement in progression-free survival with Gazyva/Gazyvaro-based therapy compared to bendamustine alone. Gazyva is marketed as Gazyvaro in the EU and Switzerland.

In May 2016, the phase III GALLIUM study in people with previously untreated follicular lymphoma met its primary endpoint early. GALLIUM compared the efficacy and safety of Gazyva/Gazyvaro plus chemotherapy (CHOP, CVP or bendamustine) followed by Gazyva/Gazyvaro alone, head-to-head with MabThera/Rituxan plus chemotherapy followed by MabThera/Rituxan alone. Results from a pre-planned interim analysis showed that Gazyva/Gazyvaro-based treatment resulted in superior progression-free survival compared to MabThera/Rituxan-based treatment. Adverse events with either Gazyva/Gazyvaro or MabThera/Rituxan were consistent with those seen in previous clinical trials when each was combined with various chemotherapies. Data from the GALLIUM study will be presented at an upcoming medical meeting and submitted to health authorities for approval consideration.
Additional combination studies investigating Gazyva/Gazyvaro with other approved or investigational medicines, including cancer immunotherapies and small molecule inhibitors, are underway across a range of blood cancers.

About DLBCL
Diffuse large B-cell lymphoma (DLBCL) is the most common subtype of non-Hodgkin lymphoma (NHL), accounting for about one in three cases of NHL1. DLBCL is an aggressive (fast-growing) type of NHL, which is generally responsive to treatment in the frontline2. However, as many as 40% of patients will relapse, at which time salvage therapy options are limited and survival is short2. Approximately 123,000 people worldwide are estimated to be diagnosed with DLBCL each year3.
