Opdivo (nivolumab) Demonstrates Statistically Significant Overall Survival Benefit Versus Chemotherapy in Patients with Advanced Esophageal Cancer

On September 30, 2019 Bristol-Myers Squibb Company (NYSE: BMY) and Ono Pharmaceutical Co., Ltd. reported results from the Phase 3 ATTRACTION-3 trial evaluating Opdivo (nivolumab) versus chemotherapy (docetaxel or paclitaxel) for the treatment of patients with unresectable advanced or recurrent esophageal squamous cell carcinoma (ESCC) refractory or intolerant to combination therapy with fluoropyrimidine and platinum-based drugs (Press release, Bristol-Myers Squibb, SEP 30, 2019, View Source [SID1234539923]). For the primary endpoint of overall survival (OS), Opdivo demonstrated a statistically significant improvement over chemotherapy, with a 23% reduction in risk of death [Hazard Ratio (HR) 0.77; 95% Confidence Interval (CI): 0.62 to 0.96; p=0.019] and a 2.5-month improvement in median OS [10.9 months (95% CI: 9.2 to 13.3)] compared to patients treated with chemotherapy [8.4 months (95% CI: 7.2 to 9.9)]. The safety profile of Opdivo in this trial was consistent with previously reported studies in ESCC and other solid tumors.

These data (Presentation #LBA11) will be featured in the Presidential Symposium on Monday, September 30 from 4:30-6:15 PM CEST at the European Society for Medical Oncology (ESMO) (Free ESMO Whitepaper) 2019 Annual Congress in Barcelona, Spain and simultaneously published in The Lancet Oncology.

Patients treated in the Opdivo arm showed 12- and 18-month OS rates of 47% (95% CI: 40 to 54) and 31% (95% CI: 24 to 37), respectively, versus 34% (95% CI: 28 to 41) and 21% (95% CI: 15 to 27) among patients in the chemotherapy arm. Survival benefit with Opdivo was observed regardless of tumor PD-L1 expression levels. An exploratory analysis of patient-reported outcomes showed significant overall improvement in quality of life with Opdivo versus chemotherapy.

"The significant survival benefit coupled with the favorable safety profile and patient-reported outcomes observed in this trial suggest Opdivo has the potential to represent an important new second-line treatment option for patients with advanced esophageal squamous cell carcinoma, offering the possibility to extend their survival and improve their quality of life during treatment," said Dr. Byoung Chul Cho, Professor, Yonsei Cancer Center, Yonsei University College of Medicine.

The objective response rates (ORR) between the two arms were comparable at 19% (95% CI: 14 to 26) among patients receiving Opdivo versus 22% (95% CI: 15 to 29) among those receiving chemotherapy. However, the study showed Opdivo substantially increased the median duration of response (DoR) for patients [6.9 months (95% CI: 5.4 to 11.1) versus 3.9 months (95% CI: 2.8 to 4.2)]. Seven patients in the Opdivo arm had ongoing responses at data cutoff compared to two patients in the chemotherapy arm. An overall HR of 1.08 (95% CI: 0.87 to 1.34) suggested no meaningful difference in progression-free survival (PFS) between the Opdivo and chemotherapy arms.

"These are very promising results for patients with advanced esophageal squamous cell carcinoma for whom prognosis is typically poor and are particularly important given Opdivo improved survival regardless of PD-L1 status," said Ian M. Waxman, M.D., development lead, Gastrointestinal Cancers, Bristol-Myers Squibb. "We are encouraged to see important progress being made in this tumor type and look forward to broadening our research in gastrointestinal tumors."

Fewer treatment-related adverse events (TRAEs) were reported with Opdivo versus chemotherapy, with a rate of 66% of any grade TRAEs for patients receiving Opdivo compared to 95% for patients receiving chemotherapy. Patients in the Opdivo arm also experienced a lower incidence of Grade 3 or 4 TRAEs compared to those in the chemotherapy arm (18% versus 63%), and the percentage of patients experiencing TRAEs leading to discontinuation was the same in both arms (9%).

About ATTRACTION-3

ATTRACTION-3 (ONO-4538-24/CA209-473; NCT02569242) is a Phase 3, multi-center, randomized, open-label global study, evaluating Opdivo versus chemotherapy (docetaxel or paclitaxel) for patients with esophageal cancer refractory or intolerant to first-line combination therapy with fluoropyrimidine and platinum-based drugs. Patient enrollment occurred predominantly in Asia with 96% of patients in both treatment arms from Asia. Patients were treated until disease progression or unacceptable toxicity. The primary endpoint of the trial is OS. Secondary endpoints include investigator-assessed ORR, PFS, disease control rate, DoR and safety. This trial was sponsored by Ono Pharmaceutical Co. Ltd. of Japan, Bristol-Myers Squibb’s development partner for Opdivo.

About Esophageal Cancer

Esophageal cancer is the seventh most common cancer and the sixth most common cause of death from cancer worldwide. The five-year relative survival rate is 8% or less for patients diagnosed with metastatic disease. The two most common types of esophageal cancer are squamous cell carcinoma and adenocarcinoma, which account for approximately 90% and 10% of all esophageal cancers, respectively. Each year, an estimated 572,000 new cases are diagnosed and approximately half a million deaths are caused by esophageal cancer. The majority of cases are diagnosed in the advanced setting and impact a patient’s daily life, including their ability to eat and drink. The prevalence of esophageal cancer is highest in Asia, with over 444,000 cases diagnosed yearly, accounting for about 80% of all esophageal cancer cases worldwide.

About Opdivo

Opdivo is a programmed death-1 (PD-1) immune checkpoint inhibitor that is designed to uniquely harness the body’s own immune system to help restore anti-tumor immune response. By harnessing the body’s own immune system to fight cancer, Opdivo has become an important treatment option across multiple cancers.

Opdivo’s leading global development program is based on Bristol-Myers Squibb’s scientific expertise in the field of Immuno-Oncology, and includes a broad range of clinical trials across all phases, including Phase 3, in a variety of tumor types. To date, the Opdivo clinical development program has treated more than 35,000 patients. The Opdivo trials have contributed to gaining a deeper understanding of the potential role of biomarkers in patient care, particularly regarding how patients may benefit from Opdivo across the continuum of PD-L1 expression.

In July 2014, Opdivo was the first PD-1 immune checkpoint inhibitor to receive regulatory approval anywhere in the world. Opdivo is currently approved in more than 65 countries, including the United States, the European Union, Japan and China. In October 2015, the Company’s Opdivo and Yervoy combination regimen was the first Immuno-Oncology combination to receive regulatory approval for the treatment of metastatic melanoma and is currently approved in more than 50 countries, including the United States and the European Union.

IMPORTANT SAFETY INFORMATION

WARNING: IMMUNE-MEDIATED ADVERSE REACTIONS

YERVOY can result in severe and fatal immune-mediated adverse reactions. These immune-mediated reactions may involve any organ system; however, the most common severe immune-mediated adverse reactions are enterocolitis, hepatitis, dermatitis (including toxic epidermal necrolysis), neuropathy, and endocrinopathy. The majority of these immune-mediated reactions initially manifested during treatment; however, a minority occurred weeks to months after discontinuation of YERVOY.

Assess patients for signs and symptoms of enterocolitis, dermatitis, neuropathy, and endocrinopathy, and evaluate clinical chemistries including liver function tests (LFTs), adrenocorticotropic hormone (ACTH) level, and thyroid function tests, at baseline and before each dose.

Permanently discontinue YERVOY and initiate systemic high-dose corticosteroid therapy for severe immune-mediated reactions.

Immune-Mediated Pneumonitis

OPDIVO can cause immune-mediated pneumonitis. Fatal cases have been reported. Monitor patients for signs with radiographic imaging and for symptoms of pneumonitis. Administer corticosteroids for Grade 2 or more severe pneumonitis. Permanently discontinue for Grade 3 or 4 and withhold until resolution for Grade 2. In patients receiving OPDIVO monotherapy, fatal cases of immune-mediated pneumonitis have occurred. Immune-mediated pneumonitis occurred in 3.1% (61/1994) of patients. In patients receiving OPDIVO 1 mg/kg with YERVOY 3 mg/kg, immune-mediated pneumonitis occurred in 6% (25/407) of patients. In RCC patients receiving OPDIVO 3 mg/kg with YERVOY 1 mg/kg, immune-mediated pneumonitis occurred in 4.4% (24/547) of patients. In MSI-H/dMMR mCRC patients receiving OPDIVO 3 mg/kg with YERVOY 1 mg/kg, immune-mediated pneumonitis occurred in 1.7% (2/119) of patients.

In Checkmate 205 and 039, pneumonitis, including interstitial lung disease, occurred in 6.0% (16/266) of patients receiving OPDIVO. Immune-mediated pneumonitis occurred in 4.9% (13/266) of patients receiving OPDIVO: Grade 3 (n=1) and Grade 2 (n=12).

Immune-Mediated Colitis

OPDIVO can cause immune-mediated colitis. Monitor patients for signs and symptoms of colitis. Administer corticosteroids for Grade 2 (of more than 5 days duration), 3, or 4 colitis.

In MSI-H/dMMR mCRC patients receiving OPDIVO 3 mg/kg with YERVOY 1 mg/kg, immune-mediated colitis occurred in 7% (8/119) of patients.

In a separate Phase 3 trial of YERVOY 3 mg/kg, severe, life-threatening, or fatal (diarrhea of ≥7 stools above baseline, fever, ileus, peritoneal signs; Grade 3-5) immune-mediated enterocolitis occurred in 34 (7%) patients. Across all YERVOY-treated patients in that trial (n=511), 5 (1%) developed intestinal perforation, 4 (0.8%) died as a result of complications, and 26 (5%) were hospitalized for severe enterocolitis.

Cytomegalovirus (CMV) infection/reactivation has been reported in patients with corticosteroid-refractory immune-mediated colitis. In cases of corticosteroid-refractory colitis, consider repeating infectious workup to exclude alternative etiologies. Addition of an alternative immunosuppressive agent to the corticosteroid therapy, or replacement of the corticosteroid therapy, should be considered in corticosteroid-refractory immune-mediated colitis if other causes are excluded.

Immune-Mediated Hepatitis

OPDIVO can cause immune-mediated hepatitis. Monitor patients for abnormal liver tests prior to and periodically during treatment. Administer corticosteroids for Grade 2 or greater transaminase elevations. For patients without HCC, withhold OPDIVO for Grade 2 and permanently discontinue OPDIVO for Grade 3 or 4. For patients with HCC, withhold OPDIVO and administer corticosteroids if AST/ALT is within normal limits at baseline and increases to >3 and up to 5 times the upper limit of normal (ULN), if AST/ALT is >1 and up to 3 times ULN at baseline and increases to >5 and up to 10 times the ULN, and if AST/ALT is >3 and up to 5 times ULN at baseline and increases to >8 and up to 10 times the ULN. Permanently discontinue OPDIVO and administer corticosteroids if AST or ALT increases to >10 times the ULN or total bilirubin increases >3 times the ULN.

Immune-Mediated Encephalitis

OPDIVO can cause immune-mediated encephalitis. Evaluation of patients with neurologic symptoms may include, but not be limited to, consultation with a neurologist, brain MRI, and lumbar puncture. Withhold OPDIVO in patients with new-onset moderate to severe neurologic signs or symptoms and evaluate to rule out other causes. If other etiologies are ruled out, administer corticosteroids and permanently discontinue OPDIVO for immune-mediated encephalitis. In patients receiving OPDIVO monotherapy, encephalitis occurred in 0.2% (3/1994) of patients. Fatal limbic encephalitis occurred in one patient after 7.2 months of exposure despite discontinuation of OPDIVO and administration of corticosteroids. Encephalitis occurred in one patient receiving OPDIVO 1 mg/kg with YERVOY 3 mg/kg (0.2%) after 1.7 months of exposure. Encephalitis occurred in one RCC patient receiving OPDIVO 3 mg/kg with YERVOY 1 mg/kg (0.2%) after approximately 4 months of exposure. Encephalitis occurred in one MSI-H/dMMR mCRC patient (0.8%) receiving OPDIVO 3 mg/kg with YERVOY 1 mg/kg after 15 days of exposure.

Other Immune-Mediated Adverse Reactions

Based on the severity of the adverse reaction, permanently discontinue or withhold OPDIVO, administer high-dose corticosteroids, and, if appropriate, initiate hormone-replacement therapy. Across clinical trials of OPDIVO monotherapy or in combination with YERVOY, the following clinically significant immune-mediated adverse reactions, some with fatal outcome, occurred in <1.0% of patients receiving OPDIVO: myocarditis, rhabdomyolysis, myositis, uveitis, iritis, pancreatitis, facial and abducens nerve paresis, demyelination, polymyalgia rheumatica, autoimmune neuropathy, Guillain-Barré syndrome, hypopituitarism, systemic inflammatory response syndrome, gastritis, duodenitis, sarcoidosis, histiocytic necrotizing lymphadenitis (Kikuchi lymphadenitis), motor dysfunction, vasculitis, aplastic anemia, pericarditis, and myasthenic syndrome.

If uveitis occurs in combination with other immune-mediated adverse reactions, consider a Vogt-Koyanagi-Harada-like syndrome, which has been observed in patients receiving OPDIVO and may require treatment with systemic steroids to reduce the risk of permanent vision loss.

Infusion-Related Reactions

OPDIVO can cause severe infusion-related reactions, which have been reported in <1.0% of patients in clinical trials. Discontinue OPDIVO in patients with Grade 3 or 4 infusion-related reactions. Interrupt or slow the rate of infusion in patients with Grade 1 or 2. In patients receiving OPDIVO monotherapy as a 60-minute infusion, infusion-related reactions occurred in 6.4% (127/1994) of patients. In a separate trial in which patients received OPDIVO monotherapy as a 60-minute infusion or a 30-minute infusion, infusion-related reactions occurred in 2.2% (8/368) and 2.7% (10/369) of patients, respectively. Additionally, 0.5% (2/368) and 1.4% (5/369) of patients, respectively, experienced adverse reactions within 48 hours of infusion that led to dose delay, permanent discontinuation or withholding of OPDIVO. In patients receiving OPDIVO 1 mg/kg with YERVOY 3 mg/kg every 3 weeks, infusion-related reactions occurred in 2.5% (10/407) of patients. In RCC patients receiving OPDIVO 3 mg/kg with YERVOY 1 mg/kg, infusion-related reactions occurred in 5.1% (28/547) of patients. In MSI-H/dMMR mCRC patients receiving OPDIVO 3 mg/kg with YERVOY 1 mg/kg, infusion-related reactions occurred in 4.2% (5/119) of patients.

Complications of Allogeneic Hematopoietic Stem Cell Transplantation

Fatal and other serious complications can occur in patients who receive allogeneic hematopoietic stem cell transplantation (HSCT) before or after being treated with a PD-1 receptor blocking antibody. Transplant-related complications include hyperacute graft-versus-host-disease (GVHD), acute GVHD, chronic GVHD, hepatic veno-occlusive disease (VOD) after reduced intensity conditioning, and steroid-requiring febrile syndrome (without an identified infectious cause). These complications may occur despite intervening therapy between PD-1 blockade and allogeneic HSCT.

Follow patients closely for evidence of transplant-related complications and intervene promptly. Consider the benefit versus risks of treatment with a PD-1 receptor blocking antibody prior to or after an allogeneic HSCT.

Embryo-Fetal Toxicity

Based on their mechanisms of action, OPDIVO and YERVOY can cause fetal harm when administered to a pregnant woman. Advise pregnant women of the potential risk to a fetus. Advise females of reproductive potential to use effective contraception during treatment with OPDIVO or YERVOY and for at least 5 months after the last dose.

Increased Mortality in Patients with Multiple Myeloma when OPDIVO is Added to a Thalidomide Analogue and Dexamethasone

In clinical trials in patients with multiple myeloma, the addition of OPDIVO to a thalidomide analogue plus dexamethasone resulted in increased mortality. Treatment of patients with multiple myeloma with a PD-1 or PD-L1 blocking antibody in combination with a thalidomide analogue plus dexamethasone is not recommended outside of controlled clinical trials.

Lactation

It is not known whether OPDIVO or YERVOY is present in human milk. Because many drugs, including antibodies, are excreted in human milk and because of the potential for serious adverse reactions in nursing infants from OPDIVO or YERVOY, advise women not to breastfeed during treatment and for at least 5 months after the last dose.

Serious Adverse Reactions

In Checkmate 037, serious adverse reactions occurred in 41% of patients receiving OPDIVO (n=268). Grade 3 and 4 adverse reactions occurred in 42% of patients receiving OPDIVO. The most frequent Grade 3 and 4 adverse drug reactions reported in 2% to <5% of patients receiving OPDIVO were abdominal pain, hyponatremia, increased aspartate aminotransferase, and increased lipase. In Checkmate 066, serious adverse reactions occurred in 36% of patients receiving OPDIVO (n=206). Grade 3 and 4 adverse reactions occurred in 41% of patients receiving OPDIVO.

Ayala Pharmaceuticals Presents Encouraging Preliminary Safety and Efficacy Data in Patients with Recurrent/Metastatic Adenoid Cystic Carcinoma with Progressing Disease and Notch Activating Mutations from Ongoing Phase 2 Clinical Trial at ESMO

On September 30, 2019 Ayala Pharmaceuticals, Inc., a clinical-stage biopharmaceutical company dedicated to developing targeted cancer therapies for people living with cancer, reported preliminary results from its ongoing Phase 2 ACCURACY study of lead investigational new drug candidate, AL101, in patients with recurrent/metastatic adenoid cystic carcinoma (ACC) with progressing disease and Notch activating mutations (Press release, Ayala Pharmaceuticals, SEP 30, 2019, View Source [SID1234539922]). The data were presented in a poster session at the European Society for Medical Oncology (ESMO) (Free ESMO Whitepaper) 2019 Congress in Barcelona, Spain.

"ACC is a devasting rare cancer that affects more than 1,300 people in the U.S. annually. Currently, there is no standard drug therapy for ACC and new treatments are desperately needed. ACC with activating NOTCH mutations represent a particularly aggressive disease subtype that can be associated with a poorer prognosis," said Alan L. Ho., M.D., Ph.D., lead investigator in the ACCURACY study. "Ayala has taken the important step of attempting to personalize therapy for ACC patients by developing AL101, a drug designed to block NOTCH activation. It has been exciting to see the encouraging disease control rates and favorable safety profile emerging from the trial to date and I look forward to continuing to help further explore the clinical utility of AL101."

"We are very pleased by the initial data from our study as we have seen early signs of biological and clinical activity and a potentially strong safety profile from AL101 in this extremely difficult to treat patient population. AL101 has been well tolerated by ACC patients, most significantly in relation to diarrhea, which has traditionally been difficult to control with previous Notch pathway inhibitors," said Gary Gordon, M.D., Ph.D., Chief Medical Officer of Ayala. "Furthermore, we are encouraged by the 22% response rate and 61% disease control rate, as most ACC patients do not respond to treatment at all. To have observed some responses after only eight weeks on therapy is a noteworthy achievement."

AL101 is an investigational small molecule, gamma-secretase inhibitor that potently and selectively inhibits Notch 1, 2, 3 and 4. AL101 inhibits the expression of Notch gene targets by blocking the final cleavage step by the gamma secretase required for Notch activation.

Trial Design:
The ongoing Phase 2 ACCURACY clinical trial is a Simon 2-stage optimal design, noncomparative, open-label, single-arm, multi-center study to assess the clinical activity of AL101 using radiographic assessments in patients with recurrent/metastatic ACC with progressing disease and Notch activating mutations. Patients were treated with 4 mg of once-weekly IV AL101 and underwent radiographic assessments every eight weeks, with an end of study visit 30 days after the last treatment and long-term follow-up every three months thereafter. Stage 1 of the study has completed enrollment and Stage 2 is ongoing. A total of 38 patients were screened and 27 have been dosed with AL101.
As of August 31, 2019, 18 of the 27 patients dosed with AL101 and had at least one pre-dosing and one post-dosing radiological evaluation. Seven patients are currently undergoing dosing and have not yet had a post-dosing radiological evaluation. Two patients began treatment, but discontinued prior to the first post-dosing radiological evaluation due to non-treatment related adverse events (AEs) and are considered to be non-evaluable for efficacy.

Preliminary Safety Results:
At the time of the cut off for data collection, treatment-related AEs were reported in ≥ 15% in patients dosed with AL101. The most common AEs included nausea (59%), diarrhea (56%, most reports were Grades 1 and 2 with one Grade 3 and zero Grade 4 events reported), fatigue (13%), cough (including productive cough) (11%), vomiting (9%), and epistaxis (6%).
Investigators reported Grade 3 AEs in three patients who experienced nausea, diarrhea and hypophosphatemia. Three treatment-related serious adverse events (SAEs) were observed, including two episodes of infusion reaction in one patient and one case of keratoacanthoma. There were two on-study, non-treatment related deaths.

Preliminary Efficacy Results:
Data presented at ESMO (Free ESMO Whitepaper) were from 18 patients with recurrent/metastatic ACC with progressing disease and Notch activating mutations treated with AL101 as of the data collection cut-off date of August 31, 2019. Based on RECIST 1.1 or modified MDA Bone Response Criteria, at the time of the cut-off date for data collection, four patients achieved a partial response (PR, 22%), seven patients achieved stable disease (SD, 39%), for a disease control rate of 61% and seven patients had progressive disease (PD, 39%).

About AL101
AL101 is an investigational small molecule, gamma-secretase inhibitor that potently and selectively inhibits Notch 1, 2, 3 and 4. AL101 inhibits the expression of Notch gene targets by blocking the final cleavage step by the gamma secretase required for Notch activation. It has the potential to inhibit tumor growth as demonstrated by three Phase 1 studies conducted by Bristol-Myers Squibb. AL101 is currently in a Phase 2 clinical trial in adenoid cystic carcinoma (ACC), as well as planned Phase 2 clinical trials for triple-negative breast cancer (TNBC) and T-Cell acute lymphoblastic leukemia (T-ALL).

About Adenoid Cystic Carcinoma (ACC)
ACC is a rare malignancy of the salivary glands, accounting for about 10% of all salivary gland tumors with an annual incidence of 1,300 in the U.S. There is currently no approved standard of care for patients with recurrent/metastatic ACC and as a result, patients undergo surgery and radiation therapy, with recurring disease treated by chemotherapy. ACC is an immunologically "cold" tumor that is refractory to chemotherapy (ORR 8%-11%), with a recurrence rate of about 60% after initial surgery.

About the Notch Signaling Pathway
The Notch signaling pathway functions as a mediator of short-range cell to cell communication and plays a fundamental role in a variety of tissue types. The gain or loss of Notch signaling aspects has been associated with a wide range of disorders, developmental syndromes and cancers, both hematological and solid tumors. The Notch pathway is involved in several hallmarks of cancer including: cellular proliferation, survival, migration, invasion, epithelial to mesenchymal transition and drug resistance, increased angiogenesis and metastasis. The Notch pathway has been determined to be an oncogenic driver of ACC and its dysregulation plays a key role in tumorigenesis and correlates with a distinct pattern of metastasis and a poor prognosis.

Lynparza more than doubled the time without radiographic disease progression in patients with BRCA1/2- or ATM-mutated metastatic castration-resistant prostate cancer

On September 30, 2019 AstraZeneca and MSD Inc., Kenilworth, N.J., US (MSD: known as Merck & Co., Inc. inside the US and Canada) reported detailed results from the Phase III PROfound trial in 387 men with metastatic castration-resistant prostate cancer (mCRPC) who have a mutation in their homologous recombination repair (HRRm) genes and whose disease had progressed on prior treatment with new hormonal agent (NHA) treatments (e.g. abiraterone or enzalutamide) (Press release, AstraZeneca, SEP 30, 2019, View Source [SID1234539921]).

The trial was designed to analyse men with HRRm genes in two cohorts: the primary endpoint was in those with mutations in BRCA1/2 or ATM genes and then, if Lynparza (olaparib) showed clinical benefit, a formal analysis was performed of the overall trial population of men with HRRm genes (BRCA1/2, ATM, CDK12 and 11 other HRRm genes; key secondary endpoint).

Results showed a statistically significant and clinically meaningful improvement with Lynparza in the primary endpoint of radiographic progression-free survival (rPFS), improving the time men with BRCA1/2- or ATM-mutated mCRPC lived without disease progression or death to a median of 7.4 months vs. 3.6 months for those treated with abiraterone or enzalutamide. Lynparza reduced the risk of disease progression or death by 66% (equal to a hazard ratio of 0.34) for these men.

The trial also met the key secondary endpoint of rPFS in the overall HRRm population, where Lynparza reduced the risk of disease progression or death by 51% (equal to a hazard ratio of 0.49) and improved rPFS to a median of 5.8 months vs. 3.5 months for abiraterone or enzalutamide.

The results were presented during the Presidential Symposium at the 2019 European Society of Medical Oncology (ESMO) (Free ESMO Whitepaper) congress in Barcelona, Spain (Abstract #LBA12_PR).

Results also showed a trend at this interim analysis time point for improvement in overall survival (OS), another key secondary endpoint, in the two groups. Lynparza extended OS to 18.5 months vs.15.1 months for abiraterone or enzalutamide in men with BRCA1/2- or ATM-mutated tumours, despite that at this interim analysis 81% of patients on NHA crossed over to Lynparza at progression. A similar trend in OS was observed at this interim analysis in the overall HRRm population with a median of 17.5 months’ OS for men treated with Lynparza vs. 14.3 months for abiraterone or enzalutamide (analysis at 41% data maturity).

José Baselga, Executive Vice President, Oncology R&D, said: "Results from PROfound demonstrate that, in addition to providing substantial benefit as a precision medicine for men with metastatic castration-resistant prostate cancer with BRCA-mutated tumours, Lynparza is effective beyond just BRCA in tumours with mutations in other genes associated with homologous recombination repair. PROfound validates the concept of PARP sensitivity across multiple genes associated with homologous recombination repair in this disease and marks the first positive Phase III trial using a molecular biomarker to identify men for targeted treatment for metastatic castration-resistant prostate cancer. We are working with global health authorities to bring Lynparza to these patients as quickly as possible."

Roy Baynes, Senior Vice President and Head of Global Clinical Development, Chief Medical Officer, MSD Research Laboratories, said: "The results from the Phase III PROfound trial are a testament to MSD and AstraZeneca’s lasting commitment to patients with cancer. The trial met the primary endpoint in men with metastatic castration-resistant prostate cancer that progressed on prior hormonal therapy, a notoriously difficult-to-treat disease. The benefit seen in patients beyond just those with BRCA mutations underscores the potential value of genomic testing in prostate cancer."

Maha Hussain, one of the principal investigators of the PROfound trial and Deputy Director of the Robert H. Lurie Comprehensive Cancer Center of Northwestern University, said: "We have seen advances in the treatment over the last 15 years for men with metastatic castration-resistant prostate cancer. However, to date treatments for this state of disease continue to use ‘one size fits all’ approaches overlooking the genomic make-up of the tumour and how it could inform treatment decisions to better personalise care and impact outcomes. I am thrilled by the PROfound results and Lynparza’s clinically meaningful benefit which offers the potential of a molecularly targeted treatment for this patient population with advanced disease. I am confident we are now entering a new era of personalised care and precision medicine for metastatic castration-resistant prostate cancer."

The safety and tolerability profile of Lynparza in the PROfound trial was in line with that observed in prior clinical trials. The most common adverse events (AEs) ≥20% were anaemia (47%), nausea (41%), fatigue/asthenia (41%), decreased appetite (30%) and diarrhoea (21%). Grade 3 or above AEs were anaemia (22%), pulmonary embolism (4%), fatigue/asthenia (3%), vomiting (2%), dyspnoea (2%), urinary tract infection (2%), decreased appetite (1%), diarrhoea (1%) and backpain (1%). 16% of patients on Lynparza discontinued treatment due to AEs.

AstraZeneca and MSD are also exploring additional trials in prostate cancer, including the ongoing Phase III PROpel trial, testing Lynparza as a 1st-line therapy in mCRPC, in combination with abiraterone.

About PROfound

PROfound is a prospective, multicentre, randomised, open-label, Phase III trial testing the efficacy and safety of Lynparza versus new hormonal agents (e.g. abiraterone or enzalutamide) in patients with mCRPC who have progressed on prior treatment with new hormonal anticancer treatments and have a qualifying tumour mutation in one of 15 genes involved in the HRR pathway, including among them BRCA1/2, ATM and CDK12.

About metastatic castration-resistant prostate cancer

Prostate cancer is the second-most common cancer in men, with an estimated 1.3 million new cases diagnosed worldwide in 2018 and is associated with a significant mortality rate.1 Development of prostate cancer is often driven by male sex hormones called androgens, including testosterone.2 mCRPC occurs when prostate cancer grows and spreads to other parts of the body despite the use of androgen-deprivation therapy to block the action of male sex hormones.2 Approximately 10-20% of men with advanced prostate cancer will develop CRPC within five years, and at least 84% of these will have metastases at the time of CRPC diagnosis.3 Of men with no metastases at CRPC diagnosis, 33% are likely to develop metastases within two years.3 Despite an increase in the number of available therapies for men with mCRPC, five-year survival remains low.3

About HRR gene mutations

HRR is a DNA repair process that allows for high-fidelity, error-free repair of damaged DNA, in the form of double-strand breaks and inter-strand crosslinks (amongst others).4,5 The inability to properly repair DNA damage leads to genomic instability and contributes to cancer aetiology.5 Deficiency in HRR leads to a compromised ability to repair damaged DNA, and is a feature of cancer cells that is a target for PARP inhibitors, such as Lynparza. PARP inhibitors block DNA damage repair by trapping of PARP bound to DNA single-strand breaks which leads to replication fork stalling causing their collapse and the generation of DNA double-strand breaks which in turn lead to cancer cell death.4

About Lynparza

Lynparza (olaparib) is a first-in-class PARP inhibitor and the first targeted treatment to block DNA damage response (DDR) in cells/tumours harbouring a deficiency in homologous recombination repair (HRR), such as mutations in BRCA1 and/or BRCA2. Inhibition of PARP with Lynparza leads to the trapping of PARP bound to DNA single-strand breaks, stalling of replication forks, their collapse and the generation of DNA double-strand breaks and cancer cell death. Lynparza is being tested in a range of PARP-dependent tumour types with defects and dependencies in the DDR pathway.

Lynparza is currently approved in 64 countries, including those in the EU, for the maintenance treatment of platinum-sensitive relapsed ovarian cancer, regardless of BRCA status. It is approved in the US, the EU, Japan and several other countries as 1st-line maintenance treatment of BRCA-mutated advanced ovarian cancer following response to platinum-based chemotherapy. It is also approved in 43 countries, including the US and Japan, for germline BRCA-mutated, HER2-negative, metastatic breast cancer, previously treated with chemotherapy; in the EU, this includes locally-advanced breast cancer. Regulatory reviews are underway in other jurisdictions for ovarian, breast and pancreatic cancers.

Lynparza, which is being jointly developed and commercialised by AstraZeneca and MSD, is approved for advanced ovarian cancer and metastatic breast cancer and has been used in over 25,000 patients worldwide. Lynparza has the broadest and most advanced clinical trial development programme of any PARP inhibitor, and AstraZeneca and MSD are working together to understand how it may affect multiple PARP-dependent tumours as a monotherapy and in combination across multiple cancer types. Lynparza is the foundation of AstraZeneca’s industry-leading portfolio of potential new medicines targeting DDR mechanisms in cancer cells.

About the AstraZeneca and MSD strategic oncology collaboration

In July 2017, AstraZeneca and Merck & Co., Inc., Kenilworth, NJ, US, known as MSD outside the United States and Canada, announced a global strategic oncology collaboration to co-develop and co-commercialise Lynparza, the world’s first PARP inhibitor, and potential new medicine selumetinib, a MEK inhibitor, for multiple cancer types. Working together, the companies will develop Lynparza and selumetinib in combination with other potential new medicines and as monotherapies. Independently, the companies will develop Lynparza and selumetinib in combination with their respective PD-L1 and PD-1 medicines.

About AstraZeneca in Oncology

AstraZeneca has a deep-rooted heritage in Oncology and offers a quickly-growing portfolio of new medicines that has the potential to transform patients’ lives and the Company’s future. With at least six new medicines to be launched between 2014 and 2020, and a broad pipeline of small molecules and biologics in development, we are committed to advance Oncology as one of AstraZeneca’s four Growth Platforms focused on lung, ovarian, breast and blood cancers. In addition to our core capabilities, we actively pursue innovative partnerships and investments that accelerate the delivery of our strategy, as illustrated by our investment in Acerta Pharma in haematology.

"Advanced cholangiocarcinoma is an aggressive disease oftentimes characterized by rapid progression following multiple lines of therapy, and there are no currently approved treatments," said Ghassan Abou-Alfa, M.D., medical oncologist at Memorial Sloan Kettering Cancer Center, who presented the data at ESMO (Free ESMO Whitepaper). "The ClarIDHy study is the first randomized trial in previously treated IDH1 mutant cholangiocarcinoma patients and demonstrates that TIBSOVO provides significant improvement in PFS compared to placebo, while also showing a favorable trend in overall survival. These critical data also provide strong justification for genomic testing in cholangiocarcinoma patients where a targeted therapeutic approach may provide benefit."

"Since we began clinical trials of TIBSOVO in solid tumors five years ago, we have hoped to provide benefit to cholangiocarcinoma patients who desperately need new treatment options. The results of the ClarIDHy trial help to establish the role that this targeted therapy may play in the treatment paradigm for patients with an IDH1 mutation," said Chris Bowden, M.D., chief medical officer at Agios. "Moving forward, we’re focused on submitting our supplemental new drug application for previously treated IDH1 mutant cholangiocarcinoma patients by the end of the year."

ClarIDHy Phase 3 Trial
The ClarIDHy trial is a global, randomized Phase 3 trial in previously treated IDH1 mutant cholangiocarcinoma patients who have documented disease progression following one or two systemic therapies in the advanced setting. Patients were randomized 2:1 to receive either single-agent TIBSOVO 500 mg once daily or placebo with crossover to TIBSOVO permitted at the time of documented radiographic progression per RECIST 1.1. As of the January 31, 2019 data cutoff, 185 patients were randomized, with 124 patients in the TIBSOVO arm and 61 patients in the placebo arm. Thirty-five patients randomized to placebo (57.4%) crossed over to open-label TIBSOVO upon radiographic disease progression and unblinding.

Efficacy Results
Efficacy data as of the data cut-off showed:

Median progression-free survival (PFS) for patients randomized to TIBSOVO was 2.7 months compared to 1.4 months with placebo (hazard ratio [HR]=0.37; 95% CI [0.25, 0.54], p<0.001) as assessed by independent radiology review. PFS benefits were observed across all subgroups analyzed.

The estimated PFS rate was 32% at six months and 22% at 12 months for patients randomized to TIBSOVO, while no patients randomized to placebo were free from progression beyond these timepoints as of the data cut-off.

In the TIBSOVO arm, 2% of patients achieved a partial response and 51% had stable disease, compared to 28% with stable disease in the placebo arm.

Median overall survival (OS) based on 78 events was 10.8 months for patients randomized to TIBSOVO compared to 9.7 months for placebo patients (HR=0.69; 95% CI [0.44, 1.10], p=0.06). Using the rank-preserving structural failure time (RPSFT) method to reconstruct the survival curve for the placebo subjects as if they never crossed over to TIBSOVO, the median OS with placebo adjusts to 6 months (HR=0.46; 95% CI [0.28, 0.75], p<0.001).

Safety Results
A safety analysis conducted for all patients as of the data cut-off demonstrated:

Less than half of patients experienced a Grade 3 or above treatment-emergent adverse event (TEAE) in either arm (46.2% with total TIBSOVO [includes patients who crossed over from placebo to TIBSOVO] vs. 35.6% on placebo), with the most common being ascites (7.7% total TIBSOVO vs. 6.8% placebo).

TEAEs leading to discontinuation were more common with placebo compared with total TIBSOVO (8.5% vs. 5.8%).

TEAEs leading to dose reductions (2.6% vs. 0%) and interruptions (26.3% vs. 16.9%) were more common with total TIBSOVO relative to placebo.

The most common TEAEs of any grade for total TIBSOVO were nausea (32%), diarrhea (29%) and fatigue (24%).

TIBSOVO is not approved in any country for the treatment of patients with advanced cholangiocarcinoma.

About Cholangiocarcinoma
Cholangiocarcinoma (CC) is a rare cancer of the bile ducts within and outside of the liver. Cases that occur within the liver are known as intrahepatic cholangiocarcinoma (IHCC) and those that occur outside the liver are considered extrahepatic. Mutations in IDH1 occur in up to 20% of IHCC cases. Current treatment options for localized disease include surgery, radiation and/or other ablative treatments. There are no approved systemic therapies for cholangiocarcinoma and limited chemotherapy options are available in the advanced setting. Gemcitabine-based chemotherapy is often recommended for newly diagnosed advanced or metastatic disease.

About TIBSOVO (ivosidenib)

TIBSOVO is indicated for the treatment of acute myeloid leukemia (AML) with a susceptible isocitrate dehydrogenase-1 (IDH1) mutation as detected by an FDA-approved test in:

Adult patients with newly-diagnosed AML who are ≥75 years old or who have comorbidities that preclude use of intensive induction chemotherapy.

Adult patients with relapsed or refractory AML.

IMPORTANT SAFETY INFORMATION

WARNING: DIFFERENTIATION SYNDROME

Patients treated with TIBSOVO have experienced symptoms of differentiation syndrome, which can be fatal if not treated. Symptoms may include fever, dyspnea, hypoxia, pulmonary infiltrates, pleural or pericardial effusions, rapid weight gain or peripheral edema, hypotension, and hepatic, renal, or multi-organ dysfunction. If differentiation syndrome is suspected, initiate corticosteroid therapy and hemodynamic monitoring until symptom resolution.

WARNINGS AND PRECAUTIONS

Differentiation Syndrome: See Boxed WARNING. In the clinical trial, 25% (7/28) of patients with newly diagnosed AML and 19% (34/179) of patients with relapsed or refractory AML treated with TIBSOVO experienced differentiation syndrome. Differentiation syndrome is associated with rapid proliferation and differentiation of myeloid cells and may be life-threatening or fatal if not treated. Symptoms of differentiation syndrome in patients treated with TIBSOVO included noninfectious leukocytosis, peripheral edema, pyrexia, dyspnea, pleural effusion, hypotension, hypoxia, pulmonary edema, pneumonitis, pericardial effusion, rash, fluid overload, tumor lysis syndrome, and creatinine increased. Of the 7 patients with newly diagnosed AML who experienced differentiation syndrome, 6 (86%) patients recovered. Of the 34 patients with relapsed or refractory AML who experienced differentiation syndrome, 27 (79%) patients recovered after treatment or after dose interruption of TIBSOVO. Differentiation syndrome occurred as early as 1 day and up to 3 months after TIBSOVO initiation and has been observed with or without concomitant leukocytosis.

If differentiation syndrome is suspected, initiate dexamethasone 10 mg IV every 12 hours (or an equivalent dose of an alternative oral or IV corticosteroid) and hemodynamic monitoring until improvement. If concomitant noninfectious leukocytosis is observed, initiate treatment with hydroxyurea or leukapheresis, as clinically indicated. Taper corticosteroids and hydroxyurea after resolution of symptoms and administer corticosteroids for a minimum of 3 days. Symptoms of differentiation syndrome may recur with premature discontinuation of corticosteroid and/or hydroxyurea treatment. If severe signs and/or symptoms persist for more than 48 hours after initiation of corticosteroids, interrupt TIBSOVO until signs and symptoms are no longer severe.

QTc Interval Prolongation: Patients treated with TIBSOVO can develop QT (QTc) prolongation and ventricular arrhythmias. One patient developed ventricular fibrillation attributed to TIBSOVO. Concomitant use of TIBSOVO with drugs known to prolong the QTc interval (e.g., anti-arrhythmic medicines, fluoroquinolones, triazole anti-fungals, 5-HT3 receptor antagonists) and CYP3A4 inhibitors may increase the risk of QTc interval prolongation. Conduct monitoring of electrocardiograms (ECGs) and electrolytes. In patients with congenital long QTc syndrome, congestive heart failure, or electrolyte abnormalities, or in those who are taking medications known to prolong the QTc interval, more frequent monitoring may be necessary.

Interrupt TIBSOVO if QTc increases to greater than 480 msec and less than 500 msec. Interrupt and reduce TIBSOVO if QTc increases to greater than 500 msec. Permanently discontinue TIBSOVO in patients who develop QTc interval prolongation with signs or symptoms of life-threatening arrhythmia.

Guillain-Barré Syndrome: Guillain-Barré syndrome occurred in <1% (2/258) of patients treated with TIBSOVO in the clinical study. Monitor patients taking TIBSOVO for onset of new signs or symptoms of motor and/or sensory neuropathy such as unilateral or bilateral weakness, sensory alterations, paresthesias, or difficulty breathing. Permanently discontinue TIBSOVO in patients who are diagnosed with Guillain-Barré syndrome.

ADVERSE REACTIONS

The most common adverse reactions including laboratory abnormalities (≥20%) were hemoglobin decreased (60%), fatigue (43%), arthralgia (39%), calcium decreased (39%), sodium decreased (39%), leukocytosis (38%), diarrhea (37%), magnesium decreased (36%), edema (34%), nausea (33%), dyspnea (32%), uric acid increased (32%), potassium decreased (32%), alkaline phosphatase increased (30%), mucositis (28%), aspartate aminotransferase increased (27%), phosphatase decreased (25%), electrocardiogram QT prolonged (24%), rash (24%), creatinine increased (24%), cough (23%), decreased appetite (22%), myalgia (21%), constipation (20%), and pyrexia (20%).

In patients with newly diagnosed AML, the most frequently reported Grade ≥3 adverse reactions (≥5%) were fatigue (14%), differentiation syndrome (11%), electrocardiogram QT prolonged (11%), diarrhea (7%), nausea (7%), and leukocytosis (7%). Serious adverse reactions (≥5%) were differentiation syndrome (18%), electrocardiogram QT prolonged (7%), and fatigue (7%). There was one case of posterior reversible encephalopathy syndrome (PRES).

In patients with relapsed or refractory AML, the most frequently reported Grade ≥3 adverse reactions (≥5%) were differentiation syndrome (13%), electrocardiogram QT prolonged (10%), dyspnea (9%), leukocytosis (8%), and tumor lysis syndrome (6%). Serious adverse reactions (≥5%) were differentiation syndrome (10%), leukocytosis (10%), and electrocardiogram QT prolonged (7%). There was one case of progressive multifocal leukoencephalopathy (PML).

DRUG INTERACTIONS

Strong or Moderate CYP3A4 Inhibitors: Reduce TIBSOVO dose with strong CYP3A4 inhibitors. Monitor patients for increased risk of QTc interval prolongation.
Strong CYP3A4 Inducers: Avoid concomitant use with TIBSOVO.
Sensitive CYP3A4 Substrates: Avoid concomitant use with TIBSOVO.

QTc Prolonging Drugs: Avoid concomitant use with TIBSOVO. If co-administration is unavoidable, monitor patients for increased risk of QTc interval prolongation.

LACTATION

Because many drugs are excreted in human milk and because of the potential for adverse reactions in breastfed children, advise women not to breastfeed during treatment with TIBSOVO and for at least 1 month after the last dose.
