Opdivo® (nivolumab) and Yervoy® (ipilimumab) Combination Regimen Shows Clinically Meaningful Responses in First-Line Advanced Non-Small Cell Lung Cancer, In Updated Phase 1b Study CheckMate -012

on June 4, 2016 Bristol-Myers Squibb Company (NYSE: BMY) reported updated results from CheckMate -012, a multi-arm, Phase 1b trial evaluating two Immuno-Oncology agents, Opdivo and Yervoy, in patients with chemotherapy-naïve advanced non-small cell lung cancer (NSCLC) (Press release, Bristol-Myers Squibb, JUN 4, 2016, View Source [SID:1234512989]). In this study, Opdivo was administered as monotherapy or as part of a combination with other agents, including Yervoy, at different doses and schedules. Data from the Opdivo monotherapy arm and other cohorts were previously reported. These updated results include findings from a pooled analysis of two Opdivo and Yervoy combination regimen cohorts, [3 mg/kg of Opdivo every two weeks plus 1 mg/kg of Yervoy either every six (Q6W) or 12 weeks (Q12W) (n=77)] which showed the magnitude of response rate from the combination regimen was enhanced with increased PD-L1 expression. In these combination regimen cohorts, the confirmed objective response rate (ORR) in patients with ≥1% PD-L1 expression was 57% and the confirmed ORR was up to 92% (n=12/13) in patients with ≥50% PD-L1 expression. In patients with <1% PD-L1 expression, the confirmed ORR was 15%. The ORR was 47% and 39% for the Q12W and Q6W, respectively in the overall population which included all patients regardless of PD-L1 expression level.

In the study, the rate of treatment related Grade 3/4 adverse events (AEs) was 37%, 33%, and 19% for the Q12W, Q6W and Opdivo monotherapy cohorts, respectively. The rate of treatment-related Grade 3/4 AEs leading to discontinuation was 5%, 8%, and 10% of patients in the Q12W, Q6W and Opdivo monotherapy arms, respectively. There were no treatment-related deaths.

These data will be presented today at the 52nd Annual Meeting of the American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) during an oral presentation on Saturday, June 4, from 1:27 PM – 1:39 PM CDT (Abstract #3001).

"The results from this study provide important insight into the combination immunotherapy with Opdivo and Yervoy, and supports the potential for this combination as a first-line treatment option for patients with advanced non-small cell lung cancer," said Matthew D. Hellmann, M.D., Memorial Sloan Kettering Cancer Center. "The frequency, depth, and durability of responses among patients in this study treated with the combination regimen, and particularly among those with increased PD-L1 expression, are promising. We look forward to additional research of this combination in the first-line setting of patients with non-small cell lung cancer."

Results from CheckMate -012 continue to support the dosing schedule selected – 3 mg/kg of Opdivo every two weeks plus 1 mg/kg of Yervoy every six weeks – for evaluation in further studies, including the Phase 3 trial, CheckMate -227, comparing Opdivo, the Opdivo and Yervoy combination regimen or Opdivo and platinum-based doublet chemotherapy versus platinum-based doublet chemotherapy in chemotherapy-naïve Stage IV or recurrent NSCLC.

Jean Viallet, M.D., Global Clinical Research Lead, Oncology, Bristol-Myers Squibb, commented, "We find these Opdivo and Yervoy combination regimen results in first-line advanced non-small cell lung cancer compelling. These data reinforce our approach to identify an optimized combination dosing schedule for further study in patients with advanced non-small cell lung cancer. As we continue to advance our Immuno-Oncology clinical research, our goal is to offer patients with first-line lung cancer the potential for improved outcomes."

About CheckMate -012

CheckMate -012 is a multi-arm Phase 1b trial evaluating the safety and tolerability of Opdivo in patients with chemotherapy-naïve advanced non-small cell lung cancer (NSCLC), as either a monotherapy or in combination with other agents including Yervoy, at different doses and schedules. The primary endpoint of the study was safety with secondary endpoints of objective response rate (ORR) and 24-week progression-free survival (PFS). Exploratory endpoints included overall survival (OS) and efficacy by PD-L1 expression. In the study, patients were tested for PD-L1 expression and 68% of patients in the Q12W cohort and 77% of patients in the Q6W cohort expressed PD-L1.

The efficacy and safety results of the three dosing schedules in CheckMate -012 reported at ASCO (Free ASCO Whitepaper) are below.

The rate of total adverse events in the Q12W (82%) and Q6W (72%) arms were comparable to monotherapy (71%). In the study, Grade 3/4 adverse events (AEs) were 37%, 33%, and 19% for the Q12W, Q6W and Opdivo monotherapy arms, respectively. Treatment-related Grade 3/4 AEs lead to discontinuation in 5% and 8% of patients in the Q12W and Q6W cohorts, respectively and were similar to Opdivo monotherapy. There were no treatment-related deaths. The treatment-related select AEs in patients administered the optimized dosing schedule (3 mg/kg of Opdivo every two weeks plus 1 mg/kg of Yervoy every six weeks) were skin related (36%), gastrointestinal (23%), endocrine (20%), and pulmonary (6%) and there were ≤5% treatment-related Grade 3/4 AEs per category.

About Lung Cancer

Lung cancer is the leading cause of cancer deaths globally, resulting in more than 1.5 million deaths each year, according to the World Health Organization. Non-small cell lung cancer (NSCLC) is one of the most common types of the disease and accounts for approximately 85% of cases. About 25% to 30% of all lung cancers are squamous cell carcinomas, and non-squamous NSCLC accounts for approximately 50% to 65% of all lung cancer cases. Survival rates vary depending on the stage and type of the cancer when it is diagnosed. Globally, the five-year survival rate for Stage I NSCLC is between 47% and 50%; for Stage IV NSCLC, the five-year survival rate drops to 2%.

Bristol-Myers Squibb & Immuno-Oncology: Advancing Oncology Research

At Bristol-Myers Squibb, we have a vision for the future of cancer care that is focused on Immuno-Oncology, now considered a major treatment choice alongside surgery, radiation, chemotherapy and targeted therapies for certain types of cancer.

We have a comprehensive clinical portfolio of investigational and approved Immuno-Oncology agents, many of which were discovered and developed by our scientists. Our ongoing Immuno-Oncology clinical program is looking at broad patient populations, across multiple solid tumors and hematologic malignancies, and lines of therapy and histologies, with the intent of powering our trials for overall survival and other important measures like durability of response. We pioneered the research leading to the first regulatory approval for the combination of two Immuno-Oncology agents, and continue to study the role of combinations in cancer.

We are also investigating other immune system pathways in the treatment of cancer including CTLA-4, CD-137, KIR, SLAMF7, PD-1, GITR, CSF1R, IDO, and LAG-3. These pathways may lead to potential new treatment options – in combination or monotherapy – to help patients fight different types of cancers.

Our collaboration with academia, as well as small and large biotech companies, to research the potential Immuno-Oncology and non-Immuno-Oncology combinations, helps achieve our goal of providing new treatment options in clinical practice.

At Bristol-Myers Squibb, we are committed to changing survival expectations in hard-to-treat cancers and the way patients live with cancer.

About Opdivo

Cancer cells may exploit "regulatory" pathways, such as checkpoint pathways, to hide from the immune system and shield the tumor from immune attack. Opdivo is a PD-1 immune checkpoint inhibitor that binds to the checkpoint receptor PD-1 expressed on activated T-cells, and blocks the binding of PD-L1 and PD-L2, preventing the PD-1 pathway’s suppressive signaling on the immune system, including the interference with an anti-tumor immune response.

Opdivo’s broad global development program is based on Bristol-Myers Squibb’s understanding of the biology behind Immuno-Oncology. Our company is at the forefront of researching the potential of Immuno-Oncology to extend survival in hard-to-treat cancers. This scientific expertise serves as the basis for the Opdivo development program, which includes a broad range of Phase 3 clinical trials evaluating overall survival as the primary endpoint across a variety of tumor types. The Opdivo trials have also contributed toward the clinical and scientific understanding of the role of biomarkers and how patients may benefit from Opdivo across the continuum of PD-L1 expression. To date, the Opdivo clinical development program has enrolled more than 18,000 patients.

Opdivo was the first PD-1 immune checkpoint inhibitor to receive regulatory approval anywhere in the world in July 2014, and currently has regulatory approval in 51 countries including the United States, Japan, and in 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 rash, defined as a rash treated with systemic or topical corticosteroids, occurred in 7% (30/406) of patients receiving OPDIVO: Grade 3 (n=4), Grade 2 (n=7), and Grade 1 (n=19). In 205 and 039, rash occurred in 22% (58/263) of patients receiving OPDIVO. Immune-mediated rash occurred in 7% (18/263) of patients on OPDIVO: Grade 3 (n=4), Grade 2 (n=3), and Grade 1 (n=11).

Immune-Mediated Encephalitis

Immune-mediated encephalitis can occur with OPDIVO treatment. 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 067, encephalitis was identified in one patient (0.2%) receiving OPDIVO with YERVOY. In 057, fatal limbic encephalitis occurred in one patient (0.3%) receiving OPDIVO. In 205 and 039, encephalitis occurred in 0.8% (2/263) of patients after allogeneic HSCT after OPDIVO.

Other Immune-Mediated Adverse Reactions

Based on the severity of adverse reaction, permanently discontinue or withhold treatment, administer high-dose corticosteroids, and, if appropriate, initiate hormone-replacement therapy. In < 1.0% of patients receiving OPDIVO, the following clinically significant, immune-mediated adverse reactions occurred: uveitis, iritis, pancreatitis, facial and abducens nerve paresis, demyelination, polymyalgia rheumatica, autoimmune neuropathy, Guillain-Barré syndrome, hypopituitarism, systemic inflammatory response syndrome, gastritis, duodenitis, and sarcoidosis. Across clinical trials of OPDIVO as a single agent administered at doses of 3 mg/kg and 10 mg/kg, additional clinically significant, immune- mediated adverse reactions were identified: motor dysfunction, vasculitis, and myasthenic syndrome.

Infusion Reactions

Severe infusion reactions have been reported in <1.0% of patients in clinical trials of OPDIVO. Discontinue OPDIVO in patients with Grade 3 or 4 infusion reactions. Interrupt or slow the rate of infusion in patients with Grade 1 or 2. In 069 and 067, infusion- related reactions occurred in 2.5% (10/407) of patients receiving OPDIVO with YERVOY: Grade 2 (n=6) and Grade 1 (n=4). In 037, 066, and 067, Grade 2 infusion related reactions occurred in 2.7% (21/787) of patients receiving OPDIVO: Grade 3 (n=2), Grade 2 (n=8), and Grade 1 (n=11). In 057, Grade 2 infusion reactions requiring corticosteroids occurred in 1.0% (3/287) of patients receiving OPDIVO. In 025, hypersensitivity/infusion-related reactions occurred in 6% (25/406) of patients receiving OPDIVO and 1.0% (4/397) of patients receiving everolimus. In 205 and 039, hypersensitivity/infusion- related reactions occurred in 16% (42/263) of patients receiving OPDIVO: Grade 3 (n=2), Grade 2 (n=24), and Grade 1 (n=16).

Complications of Allogeneic HSCT after OPDIVO

Complications, including fatal events, occurred in patients who received allogeneic HSCT after OPDIVO. Outcomes were evaluated in 17 patients from 205 and 039, who underwent allogeneic HSCT after discontinuing OPDIVO (15 with reduced-intensity conditioning, 2 with myeloablative conditioning). Thirty-five percent (6/17) of patients died from complications of allogeneic HSCT after OPDIVO. Five deaths occurred in the setting of severe or refractory GVHD. Grade 3 or higher acute GVHD was reported in 29% (5/17) of patients. Hyperacute GVHD was reported in 20% (n=2) of patients. A steroid-requiring febrile syndrome, without an identified infectious cause, was reported in 35% (n=6) of patients. Two cases of encephalitis were reported: Grade 3 (n=1) lymphocytic encephalitis without an identified infectious cause, and Grade 3 (n=1) suspected viral encephalitis. Hepatic veno-occlusive disease (VOD) occurred in one patient, who received reduced-intensity conditioned allogeneic SCT and died of GVHD and multi-organ failure. Other cases of hepatic VOD after reduced-intensity conditioned allogeneic HSCT have also been reported in patients with lymphoma who received a PD-1 receptor blocking antibody before transplantation. Cases of fatal hyperacute GVHD have also been reported. These complications may occur despite intervening therapy between PD-1 blockade and allogeneic HSCT.

Follow patients closely for early evidence of transplant-related complications such as hyperacute GVHD, severe (Grade 3 to 4) acute GVHD, steroid-requiring febrile syndrome, hepatic VOD, and other immune- mediated adverse reactions, and intervene promptly.

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 an OPDIVO- or YERVOY- containing regimen and for at least 5 months after the last dose of OPDIVO.

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 an OPDIVO-containing regimen, advise women to discontinue breastfeeding during treatment. Advise women to discontinue nursing during treatment with YERVOY and for 3 months following the final dose.

Serious Adverse Reactions

In 067, serious adverse reactions (73% and 37%), adverse reactions leading to permanent discontinuation (43% and 14%) or to dosing delays (55% and 28%), and Grade 3 or 4 adverse reactions (72% and 44%) all occurred more frequently in the OPDIVO plus YERVOY arm relative to the OPDIVO arm. The most frequent (≥10%) serious adverse reactions in the OPDIVO plus YERVOY arm and the OPDIVO arm, respectively, were diarrhea (13% and 2.6%), colitis (10% and 1.6%), and pyrexia (10% and 0.6%). In 037, serious adverse reactions occurred in 41% of patients receiving OPDIVO. 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 066, serious adverse reactions occurred in 36% of patients receiving OPDIVO. Grade 3 and 4 adverse reactions occurred in 41% of patients receiving OPDIVO. The most frequent Grade 3 and 4 adverse reactions reported in ≥2% of patients receiving OPDIVO were gamma-glutamyltransferase increase (3.9%) and diarrhea (3.4%). In 057, serious adverse reactions occurred in 47% of patients receiving OPDIVO. The most frequent serious adverse reactions reported in ≥2% of patients were pneumonia, pulmonary embolism, dyspnea, pleural effusion, and respiratory failure. In 025, serious adverse reactions occurred in 47% of patients receiving OPDIVO. The most frequent serious adverse reactions reported in ≥2% of patients were acute kidney injury, pleural effusion, pneumonia, diarrhea, and hypercalcemia. In 205 and 039, among all patients (safety population [n=263]), adverse reactions leading to discontinuation (4.2%) or to dosing delays (23%) occurred. The most frequent serious adverse reactions reported in ≥1% of patients were infusion-related reaction, pneumonia, pleural effusion, pyrexia, rash and pneumonitis. Ten patients died from causes other than disease progression, including 6 who died from complications of allogeneic HSCT. Serious adverse reactions occurred in 21% of patients in the safety population (n=263) and 27% of patients in the subset of patients evaluated for efficacy (efficacy population [n=95]).

Trials and Patient Populations

CheckMate 069 and 067 – advanced melanoma alone or in combination with YERVOY; CheckMate 037 and 066 – advanced melanoma; CheckMate 057 – non-squamous non-small cell lung cancer (NSCLC); CheckMate 025 – renal cell carcinoma; CheckMate 205/039 – classical Hodgkin lymphoma.

Encorafenib-based Regimens Provide Improved PFS and OS in Difficult-to-Treat BRAF-Mutant Colorectal Cancer Compared to Historical Benchmarks

On June 4, 2016 Array BioPharma (Nasdaq: ARRY) reported updated results from a Phase 2 study of the combination of encorafenib and cetuximab, with or without alpelisib, in patients with advanced BRAF-mutant colorectal cancer (BRAFm CRC) (Press release, Array BioPharma, JUN 4, 2016, View Source;p=RssLanding&cat=news&id=2175100 [SID:1234512988]). BRAFm CRC represents a difficult-to-treat subtype of colorectal cancer that impacts 8 to 15 percent of patients. Data from this study suggest that median overall survival (OS) for these patients may exceed one year which is more than double historical published benchmarks for this population. These data were presented at the 2016 American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Annual Meeting in Chicago (Abstract No. 3544).

With these encouraging results, Array also announced the initiation of a pivotal Phase 3 BEACON CRC (Binimetinib, Encorafenib And Cetuximab COmbiNed) to treat BRAF-mutant ColoRectal Cancer) global clinical trial, assessing the efficacy of binimetinib, encorafenib and cetuximab in comparison to cetuximab and irinotecan-based therapy.

"The BRAF mutation carries a poor prognosis for patients with advanced colorectal cancer, and is particularly unresponsive after first-line therapy," said Josep Tabernero, M.D., Ph.D., Head of the Medical Oncology Department at the Vall d’Hebron University Hospital and the Director of the Vall d’Hebron Institute of Oncology. "In the Phase 2 trial, both treatment regimens showed substantial improvement in progression-free and overall survival compared to historical published benchmarks. What’s more, median overall survival exceeded one year for these patients, again as compared to the benchmarks, which were four to six months, making a case that patients with this difficult-to-treat cancer may benefit from the combination of encorafenib-based regimens."

In the Phase 2 study, 102 patients with BRAFm CRC who had progressed after one or more prior therapies were randomized to receive the doublet regimen of encorafenib and cetuximab (ENCO 200 mg PO QD and CETUX per label; n=50) or the triplet regimen of encorafenib, cetuximab and alpelisib (ENCO, CETUX and ALP 300 mg PO QD; n=52). The Phase 2 analysis for these treatment regimens demonstrated promising clinical activity in patients:

Median OS was 12.4 and 13.1 months for the doublet and triplet regimens, respectively.
Median progression-free survival (PFS) was 4.2 and 5.4 months for the doublet and triplet regimens, respectively.
Overall response rate (ORR) was 22 percent and 27 percent for the doublet and triplet regimens, respectively.
Grade 3 or 4 adverse events (AEs) occurring in greater than 10 percent of patients included anemia, hyperglycemia and increased lipase.
Historical published median PFS and median OS results after first-line treatment range from 1.8 to 2.5 months and four to six months, respectively, and published overall response rates from various studies in this population range between 6 percent to 8 percent.

"There has been a long-standing need to find treatment options for patients with BRAF-mutant colorectal cancer, and we are encouraged that data from the Phase 2 study show encorafenib-based regimens may have this potential," said Victor Sandor, M.D., Chief Medical Officer, Array BioPharma. "We hope these promising findings will bring us one step closer to addressing this high unmet medical need, and we are pleased to be studying encorafenib-based regimens in our global, pivotal Phase 3 BEACON CRC trial in patients with this disease."

About BRAF-Mutant Colorectal Cancer
Colorectal cancer is the third most common cancer among men and women in the United States, with more than 134,000 new cases and nearly 50,000 deaths from the disease projected in 2016. In the United States, BRAF mutations occur in 8 to 15 percent of patients with colorectal cancer and represent a poor prognosis for these patients.

About RAF and encorafenib
RAF is a protein kinase in the MAPK signaling pathway (RAS-RAF-MEK-ERK) that regulates several key cellular activities including proliferation, migration, survival and angiogenesis. Inappropriate activation of this pathway has been shown to occur in many cancers, such as melanoma, colorectal, lung and thyroid cancers. Encorafenib is a late-stage small molecule BRAF inhibitor, which targets key enzymes in this pathway. It is currently being studied in Phase 3 trials in advanced cancer patients, including the COLUMBUS trial studying encorafenib in combination with binimetinib in patients with BRAF-mutant melanoma and the recently initiated BEACON trial that will study encorafenib in combination with binimetinib and cetuximab in patients with BRAF V600E-mutant colorectal cancer. Array projects COLUMBUS top-line results availability during the third quarter of 2016.

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

On June 4, 2016 ARIAD Pharmaceuticals, Inc. (NASDAQ: ARIA) reported 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 (Press release, Ariad, JUN 4, 2016, View Source;p=RssLanding&cat=news&id=2175096 [SID:1234512987]). 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) (Free ASCO Whitepaper) 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.

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

On June 4, 2016 ARIAD Pharmaceuticals, Inc. (NASDAQ: ARIA) reported 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 (Press release, Ariad, JUN 4, 2016, View Source;p=RssLanding&cat=news&id=2175095 [SID:1234512986]). 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) (Free ASCO Whitepaper) annual meeting in Chicago.

Phase 1/2 Study

The data presented at ASCO (Free ASCO Whitepaper) 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 (Free ASCO Whitepaper) 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 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; ≥ 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 ≥4% 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.
About Brigatinib

Brigatinib is an investigational, targeted cancer medicine discovered internally at ARIAD Pharmaceuticals, Inc.

Lilly Announces Results from MONARCH 1 Trial of Abemaciclib Monotherapy

On June 3, 2016 Eli Lilly and Company (NYSE: LLY) reported results from the MONARCH 1 Phase 2 study of abemaciclib, a cyclin-dependent kinase (CDK) 4 and CDK 6 inhibitor, in patients with hormone-receptor-positive (HR+), human epidermal growth factor receptor 2-negative (HER2-) metastatic breast cancer (Press release, Eli Lilly, JUN 3, 2016, View Source [SID:1234512996]). The data, which were presented at the 2016 American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Annual Meeting by Maura Dickler, M.D., of Memorial Sloan Kettering Cancer Center, showed that single-agent activity was observed in metastatic breast cancer patients, for whom endocrine therapy was no longer a suitable treatment option. The MONARCH 1 results (abstract #510) confirmed objective response (ORR), durability of response (DoR), clinical benefit rate (CBR) and progression-free survival (PFS).

The single-arm study, designed to evaluate the safety and efficacy of abemaciclib monotherapy, enrolled 132 patients who were given 200 mg of abemaciclib orally every 12 hours until disease progression. Patients enrolled in the study were heavily pretreated, having experienced progressive disease on or after prior endocrine therapy, and had received prior chemotherapy with one or two chemotherapy regimens for metastatic disease. The primary objective of the trial was investigator-assessed ORR, with secondary endpoints of DoR, CBR and PFS.

"After endocrine therapies are no longer considered appropriate for HR+ metastatic breast cancer patients, when the disease is refractory or aggressive, chemotherapy is the only option. The side effects can be distressing and may be long lasting, limiting the options for patients," said José Baselga, M.D., Ph.D., physician-in-chief and chief medical officer, Memorial Sloan Kettering Cancer Center, and senior study author. "To see this level of anti-tumor activity, combined with the toxicity profile observed in MONARCH 1, is compelling."

At the final analysis of response (minimum of 12 months follow-up), patients treated with abemaciclib achieved an ORR of 19.7 percent (95% confidence interval (CI): 13.3 – 27.5%), with a median time to response of 3.7 months and a median DoR of 8.6 months. The median PFS was six months with a CBR (defined as patients who achieved complete response, partial response or stable disease for six months or longer) of 42.4 percent. Of the 13 patients who remained on treatment at the time of this analysis, nine were responders and four had stable disease (SD).

"In this population of heavily pretreated patients with a particularly poor prognosis, abemaciclib has shown promising single agent activity and tolerability," said Richard Gaynor, M.D., senior vice president, product development and medical affairs for Lilly Oncology. "These data reinforce our belief in abemaciclib as a potential best-in-class CDK 4 and CDK 6 inhibitor and add to the growing body of evidence that sustained target inhibition can lead to improved patient outcomes."

The safety and toxicity profile of twice daily, continuously dosed abemaciclib was consistent with previous Phase 1 experience. The most common grade 3 non-laboratory treatment emergent adverse events (AEs) were diarrhea (19.7%) and fatigue (12.9%), with no grade 4 non-laboratory events reported. The most common laboratory AEs were neutropenia (22.3% grade 3, 4.6% grade 4) and leukopenia (27.4% grade 3) in this population; 7.6 percent of patients discontinued treatment due to AEs, one due to diarrhea.

Beyond MONARCH 1, Lilly has an active clinical development program studying abemaciclib in breast cancer. Abemaciclib is being evaluated in two Phase 3 clinical trials: MONARCH 2 to evaluate the combination of abemaciclib and fulvestrant for treatment of HR+, HER2- advanced or metastatic breast cancer in postmenopausal women, and MONARCH 3 to evaluate the combination of abemaciclib and a nonsteroidal aromatase inhibitor in HR+, HER2- locoregionally recurrent or metastatic breast cancer in postmenopausal women.

Lilly plans to publish further data from the MONARCH 1 trial later this year.

Breast cancer is the most common cancer in women worldwide with nearly 1.7 million new cases diagnosed in 2012.1 In the U.S. this year, approximately 246,660 new cases of invasive breast cancer will be diagnosed and about 40,450 people will die from breast cancer.2 Of all early stage breast cancer cases diagnosed in the U.S., approximately 30 percent will become metastatic, spreading to other parts of the body. In addition, an estimated six to 10 percent of all new breast cancer cases are initially diagnosed as being stage IV, or metastatic.3 Metastatic breast cancer is considered incurable, but is generally treatable.

About Abemaciclib
Abemaciclib (LY2835219) is an investigational, oral cell cycle inhibitor, designed to block the growth of cancer cells by specifically inhibiting cyclin-dependent kinases, CDK 4 and CDK 6. In many cancers, uncontrolled cell growth arises from a loss of cell cycle regulation due to increased signaling from CDK 4 and CDK 6. Abemaciclib inhibits both CDK 4 and CDK 6, and was shown in cell-free enzymatic assays to be most active against Cyclin D 1 and CDK 4.

In 2015, the U.S. Food and Drug Administration granted abemaciclib Breakthrough Therapy Designation based on data from the breast cancer cohort expansion of the company’s Phase 1 trial, JPBA, which studied the efficacy and safety of abemaciclib in women with advanced or metastatic breast cancer. In addition to its current MONARCH clinical trials evaluating abemaciclib in breast cancer, a Phase 3 trial of abemaciclib in lung cancer is also underway.
