Additionally, these data show:

Overall response rates in FL patients ranging from 76% to 89% across patient subsets analyzed (prior lines of therapy (1 vs ≥ 2) or treatment group (i.e. monotherapy or in combination with rituximab)).
Durable responses with no median yet reached (median follow-up of 13.2 months: range: 3.0-27.6) in all FL patients, across all patient subsets analyzed (prior lines of therapy (1 vs ≥ 2), treatment group (i.e. monotherapy or in combination with rituximab) or tumor bulk (< 5 cm vs ≥5 cm)).
Seven Adverse Events of Special Interest (AESI) among all patients treated on the IS schedule (n=57), with no Grade ≥3 AESI reported after Cycle 3; Four (7%) patients discontinued due to any adverse event. AESI’s include diarrhea (2), colitis (2), ALT AST (1), rash (1) and noninfectious pneumonitis (1).
The poster, titled "Tolerability and Durable Responses of the PI3Kδ Inhibitor ME-401 Administered on an Intermittent Schedule in Relapsed Refractory (R/R) Follicular Lymphoma (FL) and Other B-cell Malignancies," will be included in a poster discussion session at the ASCO (Free ASCO Whitepaper) Virtual Scientific Program and will be available for on-demand viewing online beginning on May 29, 2020 at 8:00 a.m. ET at https: /meetings.asco.org/am/virtual-program. The poster will also be available for download via the MEI Pharma website.

Andrew D. Zelenetz, M.D., Ph.D., Principal Investigator of the Phase 1b study and Professor of Medicine at Weill Cornell Medical College, Medical Director of Quality Informatics at Memorial Sloan Kettering Cancer Center, and Chair of the National Comprehensive Cancer Network’s Non-Hodgkin Lymphoma Guideline Panel, commented: "In this study, ME-401 and its intermittent dosing strategy (one week on, 3 weeks off) continues to show high response rates which are durable to date, with patients having a median of 13.2 months on therapy. Additionally, ME-401 appears well-tolerated with a low incidence of Grade 3 adverse events of interest and a correspondingly low discontinuation rate due to adverse events. ME-401 is currently being evaluated in the phase 2 TIDAL study, and if the profile we are observing is maintained, this is a therapy that could meaningfully expand the role of PI3Kδ in the treatment of B-cell malignancies."

Daniel P. Gold, Ph.D., president and chief executive officer of MEI Pharma, added: "The ME-401 Phase 1b data continues to generate consistent efficacy and safety data across groups, including as a monotherapy and in combination with rituximab, which we believe underscores the compelling opportunity to provide an important new potential option to patients with B-cell malignancies. We are particularly encouraged that the follicular lymphoma patients in the Phase 1b study – the focus of our ongoing Phase 2 TIDAL study – now have a median time on therapy in excess of 1 year with responses that are durable to date while remaining generally well-tolerated."

Yoshifumi Torii, Ph.D., Vice President, Head of R&D Division of Kyowa Kirin, said "We believe this data is encouraging and shows the potential for a meaningful response rate and duration of response in patients with B-cell malignancies. We are working closely with MEI Pharma to expand the global development program for ME-401 and understand its potential for treating patients with B-cell malignancies worldwide."

The Phase 2 TIDAL (Trials of PI3K DeltA in Non-Hodgkin’s Lymphoma) study is evaluating patients with r r FL, and may support an accelerated approval of a marketing application with the U.S. Food and Drug Administration.

ME-401 is not yet licensed or approved anywhere globally and has not yet been demonstrated to be safe or effective for the treatment of follicular lymphoma and other B-cell malignancies.

ME-401 Phase 1b Clinical Study
The ongoing Phase 1b clinical study is a multi-arm, open-label, Phase 1b dose escalation and expansion trial evaluating ME-401 as a monotherapy and in combination with other therapies in patients with relapsed or refractory B-cell malignancies. The data reported today is for patients receiving ME-401 administered on the intermittent schedule: once daily at 60 mg for two 28-day cycles and then on an intermittent schedule of once daily dosing for the first 7 days of each subsequent 28-day cycle (i.e. the intermittent schedule or IS). A total of 57 patients have been treated with ME-401 on the intermittent schedule, including 36 patients with r r FL, 10 patients with r/r chronic lymphocytic leukemia (CLL), and 11 patients with other B-cell malignancies.

The overall response rate in 36 patients with r r FL was 83%, with 22% achieving a complete response. The overall response rate was 76% in 17 patients administered ME-401 as a monotherapy and 89% in 19 patients administered ME-401 in combination with rituximab. The overall response rate in 9 evaluable patients with CLL was 89%.

Median duration of response in patients with FL has not yet been reached and median follow-up is 13.2 months (range: 3.0-27.6). Responses appear durable across patient subsets analyzed (prior lines of therapy (1 vs ≥ 2), treatment group (i.e. monotherapy or in combination with rituximab) or tumor bulk (< 5 cm vs ≥5 cm)).

Duration of Response – All FL Patients (N=30)

ME-401 was generally well-tolerated. The rate of drug related grade 3 AESI is: diarrhea 3.5% (2 57); colitis 3.5% (2/57); rash 1.8% (1/57); ALT/AST elevation 1.8% (1/57); non-infectious pneumonitis 1.8% (1/57). No grade ≥3 AESI has been reported after Cycle 3, when patients are treated with the IS, and the discontinuation rate due to adverse events is 7% (4/57). There were no isolated grade 3 elevations in ALT and AST: such elevations were transient and in each case were associated with grade 3 diarrhea or rash.

About ME-401
ME-401 is an investigational cancer treatment being developed as an oral, once-daily, selective PI3Kδ inhibitor for the treatment of B-cell malignancies is ongoing. In March 2020 the U.S. FDA granted ME-401 Fast Track designation.

In April 2020 MEI and Kyowa Kirin entered a global license, development and commercialization agreement to further develop and commercialize ME-401. MEI and Kyowa Kirin will co-develop and co-promote ME-401 in the U.S., with MEI booking all revenue from U.S. sales. Kyowa Kirin has exclusive commercialization rights outside of the U.S.

MEI is currently conducting two ongoing studies evaluating ME-401. The first is a Phase 2 clinical trial evaluating ME-401 as a monotherapy for the treatment of adults with r r FL after failure of at least two prior systemic therapies including chemotherapy and an anti-CD20 antibody. Subject to the results, upon completion of the Phase 2 clinical trial, ME-401 is planned to be submitted to FDA to support an accelerated approval marketing application under 21 CFR Part 314.500, Subpart H. The second study is a multi-arm, open-label, Phase 1b dose escalation and expansion trial evaluating ME-401 as a monotherapy and in combination with other therapies or investigational agents in patients with relapsed or refractory B-cell malignancies. Additionally, a Phase 1 study was initiated by Kyowa Kirin in 2019 evaluating ME-401 as a monotherapy in patients with indolent B-cell malignancy in Japan.

Opdivo (nivolumab) Plus Yervoy (ipilimumab) with Limited Chemotherapy Significantly Improves Overall Survival vs. Chemotherapy Alone for Patients with First-Line Metastatic Non-Small Cell Lung Cancer in CheckMate -9LA Study

On May 13, 2020 Bristol Myers Squibb (NYSE: BMY) reported the first presentation of results from the Phase 3 CheckMate -9LA trial, which demonstrated a statistically significant and clinically meaningful survival benefit with Opdivo (nivolumab) plus Yervoy (ipilimumab), given concomitantly with two cycles of chemotherapy, for the first-line treatment of metastatic non-small cell lung cancer (NSCLC) (Press release, Bristol-Myers Squibb, MAY 13, 2020, View Source [SID1234557911]). The study met both its primary and key secondary endpoints, demonstrating superior overall survival (OS), progression-free survival (PFS) and overall response rate (ORR) for the dual immunotherapy plus chemotherapy combination versus chemotherapy alone.

At a prespecified interim analysis for the primary endpoint of OS, Opdivo plus Yervoy combined with two cycles of chemotherapy reduced the risk of death by 31% compared to chemotherapy alone at a minimum follow-up of 8.1 months [Hazard Ratio (HR): 0.69, 96.71% Confidence Interval (CI): 0.55 to 0.87; p=0.0006]. Additionally, with longer follow-up (minimum of 12.7 months), the combination continued to show sustained OS improvements over chemotherapy alone (median OS of 15.6 months versus 10.9 months, respectively [HR: 0.66, 95% CI: 0.55 to 0.80]). The clinical benefit was observed across all efficacy measures in key population subgroups, including by PD-L1 expression and tumor histology (squamous or non-squamous).

The safety profile of Opdivo (360 mg every three weeks) plus Yervoy (1 mg/kg every six weeks) and two cycles of chemotherapy was reflective of the known safety profiles of the immunotherapy and chemotherapy components in first-line NSCLC. These results (Abstract #9501) will be featured in an oral session at the American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Annual Meeting 2020, held virtually, from May 29-31.

"The nivolumab plus ipilimumab combination has been shown to increase survival in patients with first-line non-small cell lung cancer, and adding a limited course of chemotherapy may help mitigate the risk of early disease progression," said Martin Reck, M.D., Ph.D., CheckMate -9LA study investigator, Lung Clinic Grosshansdorf, German Center of Lung Research. "With these results from CheckMate -9LA, we now have evidence that this dual immunotherapy combination, when administered concomitantly with two cycles of chemotherapy, provides a survival benefit in this setting – a benefit that was observed early and sustained at one year of follow-up across key subgroups of patients. As the data become more mature, I see the potential for an improving survival benefit over time."

With a minimum follow-up of 12.7 months, Opdivo plus Yervoy with limited chemotherapy improved OS regardless of PD-L1 expression levels, reducing the risk of death by 38% in patients with PD-L1 <1% (HR: 0.62, 95% CI: 0.45 to 0.85) and by 36% in patients with PD-L1 ≥ 1% (HR: 0.64, 95% CI: 0.50 to 0.82). In addition, the dual immunotherapy and chemotherapy combination demonstrated a one-year PFS rate of 33% versus 18% for chemotherapy (HR: 0.68, 95% CI: 0.57 to 0.82), and an ORR of 38% compared to 25% with chemotherapy alone.

"Understanding that each patient facing a diagnosis of metastatic non-small lung cancer is unique, we’ve approached our development program with the goal of delivering a number of potentially durable solutions for the significant number of first-line patients who still need new options," said Nick Botwood, M.D., vice president, Oncology Clinical Development, Bristol Myers Squibb. "The updated one-year overall survival data from CheckMate -9LA, along with three-year results from our CheckMate -227 trial, further reinforce the clinical value of Opdivo plus Yervoy-based combinations, the first-ever dual immunotherapy options for the treatment of first-line non-small cell lung cancer."

Opdivo plus Yervoy is a unique combination of two immune checkpoint inhibitors that features a potentially synergistic mechanism of action, targeting two different checkpoints (PD-1 and CTLA-4) to help destroy tumor cells: Yervoy helps activate and proliferate T cells, while Opdivo helps existing T cells discover the tumor. Some of the T cells stimulated by Yervoy can become memory T cells, which may allow for a long-term immune response. The addition of limited chemotherapy to the Opdivo plus Yervoy combination may help patients achieve early disease control.

About CheckMate -9LA

CheckMate -9LA is an open-label, multi-center, randomized Phase 3 trial evaluating Opdivo (360 mg Q3W) plus Yervoy (1 mg/kg Q6W) combined with chemotherapy (two cycles) compared to chemotherapy alone (up to four cycles followed by optional pemetrexed maintenance therapy if eligible) as a first-line treatment in patients with metastatic non-small cell lung cancer (NSCLC) regardless of PD-L1 expression and histology. Patients in the experimental arm were treated with immunotherapy for up to two years or until disease progression or unacceptable toxicity. Patients in the control arm were treated with up to four cycles of chemotherapy and optional pemetrexed maintenance (if eligible) until disease progression or unacceptable toxicity. The primary endpoint of the trial was overall survival (OS) in the intent-to-treat (ITT) population. Secondary hierarchical endpoints included progression-free survival (PFS) and overall response rate (ORR), and the study also evaluated efficacy measures according to biomarkers.

About Lung Cancer

Lung cancer is the leading cause of cancer deaths globally. The two main types of lung cancer are non-small cell and small cell. Non-small cell lung cancer (NSCLC) is one of the most common types of lung cancer and accounts for up to 84% of diagnoses. Survival rates vary depending on the stage and type of the cancer when diagnosed. For patients diagnosed with metastatic lung cancer, the five-year survival rate is approximately 5%.

Bristol Myers Squibb: Advancing Cancer Research

At Bristol Myers Squibb, patients are at the center of everything we do. The goal of our cancer research is to increase patients’ quality of life, long-term survival and make cure a possibility. We harness our deep scientific experience, cutting-edge technologies and discovery platforms to discover, develop and deliver novel treatments for patients.

Building upon our transformative work and legacy in hematology and Immuno-Oncology that has changed survival expectations for many cancers, our researchers are advancing a deep and diverse pipeline across multiple modalities. In the field of immune cell therapy, this includes registrational CAR T cell agents for numerous diseases, and a growing early-stage pipeline that expands cell and gene therapy targets, and technologies. We are developing cancer treatments directed at key biological pathways using our protein homeostasis platform, a research capability that has been the basis of our approved therapies for multiple myeloma and several promising compounds in early- to mid-stage development. Our scientists are targeting different immune system pathways to address interactions between tumors, the microenvironment and the immune system to further expand upon the progress we have made and help more patients respond to treatment. Combining these approaches is key to delivering potential new options for the treatment of cancer and addressing the growing issue of resistance to immunotherapy. We source innovation internally, and in collaboration with academia, government, advocacy groups and biotechnology companies, to help make the promise of transformational medicines a reality for patients.

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.

About Yervoy

Yervoy is a recombinant, human monoclonal antibody that binds to the cytotoxic T-lymphocyte-associated antigen-4 (CTLA-4). CTLA-4 is a negative regulator of T-cell activity. Yervoy binds to CTLA-4 and blocks the interaction of CTLA-4 with its ligands, CD80/CD86. Blockade of CTLA-4 has been shown to augment T-cell activation and proliferation, including the activation and proliferation of tumor infiltrating T-effector cells. Inhibition of CTLA-4 signaling can also reduce T-regulatory cell function, which may contribute to a general increase in T-cell responsiveness, including the anti-tumor immune response. On March 25, 2011, the U.S. Food and Drug Administration (FDA) approved Yervoy 3 mg/kg monotherapy for patients with unresectable or metastatic melanoma. Yervoy is approved for unresectable or metastatic melanoma in more than 50 countries. There is a broad, ongoing development program in place for Yervoy spanning multiple tumor types.

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 melanoma patients receiving OPDIVO 1 mg/kg with YERVOY 3 mg/kg, immune-mediated pneumonitis occurred in 6% (25/407) of patients. In HCC patients receiving OPDIVO 1 mg/kg with YERVOY 3 mg/kg, immune-mediated pneumonitis occurred in 10% (5/49) 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.

Immune-Mediated 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. In patients receiving OPDIVO monotherapy, immune-mediated hepatitis occurred in 1.8% (35/1994) of patients.

All 9 patients had hypopituitarism, and some had additional concomitant endocrinopathies such as adrenal insufficiency, hypogonadism, and hypothyroidism. Six of the 9 patients were hospitalized for severe endocrinopathies.

Immune-Mediated Nephritis and Renal Dysfunction

OPDIVO can cause immune-mediated nephritis. Monitor patients for elevated serum creatinine prior to and periodically during treatment. Administer corticosteroids for Grades 2-4 increased serum creatinine. Withhold OPDIVO for Grade 2 or 3 and permanently discontinue for Grade 4 increased serum creatinine. In patients receiving OPDIVO monotherapy, immune-mediated nephritis and renal dysfunction occurred in 1.2% (23/1994) of patients. In melanoma patients receiving OPDIVO 1 mg/kg with YERVOY 3 mg/kg, immune-mediated nephritis and renal dysfunction occurred in 2.2% (9/407) of patients. In RCC patients receiving OPDIVO 3 mg/kg with YERVOY 1 mg/kg, immune-mediated nephritis and renal dysfunction occurred in 4.6% (25/547) of patients. In MSI-H/dMMR mCRC patients receiving OPDIVO 3 mg/kg with YERVOY 1 mg/kg, immune-mediated nephritis and renal dysfunction occurred in 1.7% (2/119) of patients.

Immune-Mediated Skin Adverse Reactions and Dermatitis

OPDIVO can cause immune-mediated rash, including Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN), some cases with fatal outcome. Administer corticosteroids for Grade 3 or 4 rash. Withhold for Grade 3 and permanently discontinue for Grade 4 rash. For symptoms or signs of SJS or TEN, withhold OPDIVO and refer the patient for specialized care for assessment and treatment; if confirmed, permanently discontinue. In patients receiving OPDIVO monotherapy, immune-mediated rash occurred in 9% (171/1994) of patients. In melanoma patients receiving OPDIVO 1 mg/kg with YERVOY 3 mg/kg, immune-mediated rash occurred in 22.6% (92/407) of patients. In HCC patients receiving OPDIVO 1 mg/kg with YERVOY 3 mg/kg, immune-mediated rash occurred in 35% (17/49) of patients. In RCC patients receiving OPDIVO 3 mg/kg with YERVOY 1 mg/kg, immune-mediated rash occurred in 16% (90/547) of patients. In MSI-H/dMMR mCRC patients receiving OPDIVO 3 mg/kg with YERVOY 1 mg/kg, immune-mediated rash occurred in 14% (17/119) of patients.

In a separate Phase 3 trial of YERVOY 3 mg/kg, severe, life-threatening, or fatal immune-mediated dermatitis (eg, Stevens-Johnson syndrome, toxic epidermal necrolysis, or rash complicated by full thickness dermal ulceration, or necrotic, bullous, or hemorrhagic manifestations; Grade 3-5) occurred in 13 (2.5%) patients. 1 (0.2%) patient died as a result of toxic epidermal necrolysis. 1 additional patient required hospitalization for severe dermatitis.

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 melanoma 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 melanoma 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 HCC patients receiving OPDIVO 1 mg/kg with YERVOY 3 mg/kg, infusion-related reactions occurred in 8% (4/49) 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.

Embryo-Fetal Toxicity

Based on mechanism 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 067, serious adverse reactions (74% and 44%), adverse reactions leading to permanent discontinuation (47% and 18%) or to dosing delays (58% and 36%), and Grade 3 or 4 adverse reactions (72% and 51%) all occurred more frequently in the OPDIVO plus YERVOY arm (n=313) relative to the OPDIVO arm (n=313). The most frequent (≥10%) serious adverse reactions in the OPDIVO plus YERVOY arm and the OPDIVO arm, respectively, were diarrhea (13% and 2.2%), colitis (10% and 1.9%), and pyrexia (10% and 1.0%).

NUBEQA® (darolutamide) Plus Androgen Deprivation Therapy Showed a Statistically Significant Improvement in Overall Survival with Proven Efficacy and Tolerability in Men with Non-Metastatic Castration-Resistant Prostate Cancer

On May 13, 2020 Bayer reported that NUBEQA (darolutamide) plus androgen deprivation therapy (ADT) is shown to significantly improve overall survival (OS) compared to ADT alone, in men with non-metastatic castration-resistant prostate cancer (nmCRPC) (Press release, Bayer, MAY 13, 2020, View Source [SID1234557910]).1 These data from the pre-specified final OS analysis of the Phase III ARAMIS trial will be presented at the American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) 2020 Virtual Scientific Program, which takes place from May 29-31, 2020.

Previously published results in 1,509 patients from the Phase III ARAMIS trial demonstrated a highly significant improvement in the primary efficacy endpoint of metastasis-free survival (MFS), with a median of 40.4 months (n=955) with NUBEQA plus ADT, compared to 18.4 months (n=554) for placebo plus ADT (p<0.001); however OS data were not yet mature at the time of the MFS analysis.2 MFS is defined as the time from randomization to the time of first evidence of blinded independent central review (BICR)-confirmed distant metastasis or death from any cause within 33 weeks after the last evaluable scan, whichever occurred first. Adverse reactions occurring more frequently in the NUBEQA arm (≥2 percent over placebo) were fatigue (16 percent versus 11 percent), pain in extremity (6 percent versus 3 percent) and rash (3 percent versus 1 percent).2 NUBEQA was not studied in women and there is a warning and precaution for embryo-fetal toxicity.2

"Men with nmCRPC typically do not have cancer symptoms. In selecting a treatment for these patients, my goal as a clinician is to improve their overall survival while limiting side effects and drug interactions," said Karim Fizazi, M.D., Ph.D., Professor of Medicine at the Institut Gustave Roussy, Villejuif, France. "These data add to the growing evidence for darolutamide as an effective treatment option with proven tolerability that extends patients’ lives and delays cancer symptoms."

Final OS Analysis Presented at ASCO (Free ASCO Whitepaper) Virtual Scientific Program

Men receiving NUBEQA plus ADT showed a statistically significant improvement in the secondary endpoint of OS compared to ADT alone, with a 31 percent reduction in risk of death (HR=0.69, 95% CI 0.53-0.88; p=0.003).1

With extended follow-up, any grade treatment-emergent adverse events (AEs) at final analysis were generally consistent with the primary analysis of the Phase III ARAMIS trial.1,2 Previously, in the primary analysis, any grade AEs occurred in 83.2 percent who received NUBEQA plus ADT and 76.9 percent who received ADT alone.2 Grade 3 or 4 AEs occurred in 24.7 percent who received NUBEQA plus ADT and 19.5 percent who received ADT alone.2 Grade 5 AEs occurred in 3.9 percent who received NUBEQA plus ADT and 3.2 percent who received ADT alone.2 Serious AEs occurred in 24.8 percent receiving NUBEQA plus ADT and in 20.0 percent receiving ADT alone.2 The percentage who discontinued the trial regimen because of AEs was 8.9 percent in the NUBEQA plus ADT group and 8.7 percent in the ADT group.2

Previously, OS data were not mature at the time of MFS analysis (57 percent of the required number of events).2 Secondary endpoints were evaluated in a hierarchical order, with a significance level of 0.05 split between the primary analysis and final analysis (planned to occur after 240 deaths from any cause) of secondary endpoints.1,2 The endpoint OS was used to determine the alpha spend and significance threshold for each of the secondary endpoints.2 Given the OS analysis did not meet the threshold for statistical significance, this prevented all of the secondary endpoints from meeting the criteria for statistical significance at the interim analysis.2

In the follow-up analysis of the same secondary endpoints, all were statistically significant.1 NUBEQA plus ADT showed statistical significance in delaying time to pain progression (HR=0.65, 95% CI 0.53-0.79; p<0.001), time to first initiation of treatment with cytotoxic chemotherapy (HR=0.58, 95% CI 0.44-0.76; p<0.001) and time to first symptomatic skeletal event (SSE) (HR=0.48, 95% CI 0.29-0.82; p=0.005) versus ADT alone.1

Time to pain progression was defined as at least a 2-point worsening from baseline of the pain score on Brief Pain Inventory-Short Form or initiation of opioids, in patients treated with NUBEQA as compared to ADT alone. Pain progression was reported in 28 percent of all patients at the interim analysis.

About NUBEQA (darolutamide)3

NUBEQA is an androgen receptor inhibitor (ARi) with a distinct chemical structure that competitively inhibits androgen binding, AR nuclear translocation, and AR-mediated transcription.3 A Phase III study in metastatic hormone-sensitive prostate cancer (ARASENS) is ongoing. Information about this trial can be found at www.clinicaltrials.gov.

On July 30th, 2019, the FDA approved NUBEQA (darolutamide) based on the ARAMIS trial, a randomized, double-blind, placebo-controlled, multi-center Phase III study, which evaluated the safety and efficacy of oral NUBEQA in patients with nmCRPC who were receiving a concomitant gonadotropin-releasing hormone (GnRH) analog or had a bilateral orchiectomy. In the clinical study, 1,509 patients were randomized in a 2:1 ratio to receive 600 mg of NUBEQA orally twice daily or ADT alone. The primary efficacy endpoint was MFS.

Adverse reactions occurring more frequently in the NUBEQA arm (≥2 % over placebo) were fatigue (16% versus 11%), pain in extremity (6% versus 3%) and rash (3% versus 1%). NUBEQA was not studied in women and there is a warning and precaution for embryo-fetal toxicity.

Developed jointly by Bayer and Orion Corporation, a globally operating Finnish pharmaceutical company, NUBEQA is indicated for the treatment of men with nmCRPC.3 The approvals of NUBEQA in the U.S., European Union (EU), Australia, Brazil, Canada, and Japan have been based on the pivotal Phase III ARAMIS trial data evaluating the efficacy and safety of NUBEQA plus ADT compared to ADT alone.3 Filings in other regions are underway or planned.

INDICATION

NUBEQA is approved for the treatment of patients with non-metastatic castration-resistant prostate cancer (nmCRPC).3

IMPORTANT SAFETY INFORMATION

Embryo-Fetal Toxicity: Safety and efficacy of NUBEQA have not been established in females. NUBEQA can cause fetal harm and loss of pregnancy. Advise males with female partners of reproductive potential to use effective contraception during treatment with NUBEQA and for 1 week after the last dose.

Adverse Reactions

Serious adverse reactions occurred in 25% of patients receiving NUBEQA and in 20% of patients receiving placebo. Serious adverse reactions in ≥ 1 % of patients who received NUBEQA were urinary retention, pneumonia, and hematuria. Overall, 3.9% of patients receiving NUBEQA and 3.2% of patients receiving placebo died from adverse reactions, which included death (0.4%), cardiac failure (0.3%), cardiac arrest (0.2%), general physical health deterioration (0.2%), and pulmonary embolism (0.2%) for NUBEQA.

Adverse reactions occurring more frequently in the NUBEQA arm (≥2% over placebo) were fatigue (16% vs. 11%), pain in extremity (6% vs. 3%) and rash (3% vs. 1%).

Clinically significant adverse reactions occurring in ≥ 2% of patients treated with NUBEQA included ischemic heart disease (4.0% vs. 3.4% on placebo) and heart failure (2.1% vs. 0.9% on placebo).

Drug Interactions

Effect of Other Drugs on NUBEQA –Concomitant use of NUBEQA with a combined P-gp and strong or moderate CYP3A4 inducer decreases darolutamide exposure, which may decrease NUBEQA activity. Avoid concomitant use of NUBEQA with combined P-gp and strong or moderate CYP3A4 inducers.

Concomitant use of NUBEQA with a combined P-gp and strong CYP3A4 inhibitor increases darolutamide exposure, which may increase the risk of NUBEQA adverse reactions. Monitor patients more frequently for NUBEQA adverse reactions and modify NUBEQA dosage as needed.

Effects of NUBEQA on Other Drugs –NUBEQA is an inhibitor of breast cancer resistance protein (BCRP) transporter. Concomitant use of NUBEQA increases the exposure (AUC) and maximal concentration of BCRP substrates, which may increase the risk of BCRP substrate-related toxicities. Avoid concomitant use with drugs that are BCRP substrates where possible. If used together, monitor patients more frequently for adverse reactions, and consider dose reduction of the BCRP substrate drug. Consult the approved product labeling of the BCRP substrate when used concomitantly with NUBEQA.

For important risk and use information about NUBEQA, please see the accompanying full Prescribing Information.

About Prostate Cancer

Prostate cancer is the second most commonly diagnosed malignancy in men worldwide.4 In 2020, about 192,000 men in the U.S. will be diagnosed with prostate cancer and an estimated 33,000 will die from the disease.5 Prostate cancer is the fifth leading cause of death from cancer in men.4 Prostate cancer results from the abnormal proliferation of cells within the prostate gland, which is part of a man’s reproductive system.6 It mainly affects men over the age of 50, and the risk increases with age.7

Treatment options range from surgery to radiation treatment to therapy using hormone-receptor antagonists, i.e., substances that stop the formation of testosterone or prevent its effect at the target location.8 However, in nearly all cases, the cancer eventually becomes resistant to conventional hormone therapy.9

Castration-resistant prostate cancer (CRPC) is an advanced form of the disease where the cancer keeps progressing even when the amount of testosterone is reduced to very low levels in the body. The field of treatment options for castration-resistant patients is evolving rapidly for CRPC patients who have prostate cancer that has not spread to other parts of the body with rising prostate-specific antigen (PSA) levels despite a castrate testosterone level, which is called non-metastatic castration-resistant prostate cancer, or nmCRPC.10,11 About one-third of men with nmCRPC go on to develop metastases within two years.12 In men with progressive nmCRPC, a short PSA doubling time is correlated with shortened time to first metastasis and death.11

Clinical Developments

DM199 for the Treatment of Acute Ischemic Stroke

DM199 Acute Ischemic Stroke Phase II "ReMEDy" Trial – Positive Top-Line Data

DiaMedica reported positive top-line results from its ReMEDy trial, a Phase II study assessing the safety, tolerability and therapeutic potential of DM199 in participants suffering from AIS. Final enrollment was 92 participants. The markers of therapeutic efficacy included the National Institutes of Health Stroke Scale, Modified Rankin Scale and the Barthel Index and multiple plasma-based biomarkers (e.g. C-reactive protein). These markers were assessed at multiple points throughout the study, including 90 days post-stroke.

DM199 met primary safety and tolerability endpoints and no DM199-related serious adverse events were noted in the study. According to top-line phase II results, there was also a demonstrated therapeutic effect in participants who received tissue plasminogen activator (tPA) prior to enrollment, but not in participants receiving mechanical thrombectomy.

"We are very excited about the positive top-line results which continue to demonstrate the excellent safety profile of DM199 and efficacy signals which are consistent with the approval study for Kailikang, the urine-derived form of KLK1 which has been used to successfully treat stroke patients in China for years," stated Rick Pauls, DiaMedica’s President and CEO. "These results strengthen our belief that DM199 can be a valuable treatment option for stroke victims, improving outcomes while providing a significantly longer, up to 24 hours, after onset of the stroke. We look forward to discussing a path to commercialization with the FDA."

DM199 for the Treatment of Chronic Kidney Disease

Phase II Clinical Study in CKD Caused by IgA Nephropathy and in African Americans with Hypertension – Enrollment Continues

The Phase II REDUX (latin for restore) trial is a multi-center, open-label investigation of approximately 60 participants with chronic kidney disease (CKD), who are being enrolled in two cohorts (30 per cohort). The study is ongoing in the United States at 12 sites and targets participants with CKD: Cohort I is enrolling non-diabetic, hypertensive African Americans with Stage II or III CKD, a group which is at greater risk for CKD than Caucasians. African Americans who have the APOL1 gene mutation are at an even higher risk. The study is designed to capture the APOL1 gene mutation as an exploratory biomarker in this cohort. Cohort II is enrolling participants with IgA Nephropathy (IgAN). The overall study evaluates two dose levels of DM199. Study participants in each cohort will receive DM199 by subcutaneous injection twice weekly for 95 days. The primary study endpoints include safety, tolerability, blood pressure, proteinuria and kidney function, which will be evaluated by changes from baseline in estimated glomerular filtration rate (eGFR) and albuminuria, as measured by the urinary albumin to creatinine ratio (UACR).

Due to actions implemented to combat the novel strain of the coronavirus (COVID-19) pandemic, the Company is experiencing slower than expected enrollment in the REDUX clinical study as activities are reduced or suspended at the clinical study sites as they address staff and patient safety concerns.The Company currently expects a delay in the timing of costs incurred as a result of the COVID-19 pandemic, but not a significant overall increase. The Company will continue to assess the effect of the pandemic on its REDUX trial by monitoring the spread of the COVID-19 virus and the actions implemented to combat the virus.

"Our highest priority right now is to protect the safety of subjects and clinical staff participating in the REDUX trial, and we believe that we have accomplished that" commented Dr. Harry Alcorn, DiaMedica’s Chief Medical Officer. "While enrollment has significantly slowed, we believe that the measures taken will allow our study to resume more normal rates of enrollment as COVID-19 related restrictions are eased."

Public Offering of Common Shares

On February 13, 2020, the Company issued and sold an aggregate of 2,125,000 common shares in a public, underwritten offering at a public offering price of $4.00 per share. As a result of the offering, the Company received gross proceeds of $8.5 million and net proceeds of $7.7 million, after deducting the underwriting discount and offering expenses.

Financial Results

Research and development (R&D) expenses were $1.4 million for the three months ended March 31, 2020, compared with $2.6 million for the three months ended March 31, 2019, a decrease of $1.2 million. The decrease was due to costs incurred during the first quarter of 2019 which did not reoccur during the first quarter of 2020, primarily the costs for a production run of the DM199 drug substance and the Phase Ib study in CKD patients. Declining costs for the ReMEDy study in the current year period also contributed to the decrease. These decreases were partially offset by costs incurred for the REDUX study, which began enrollment in December 2019, and increased non-cash share-based compensation costs.

General and administrative (G&A) expenses were $1.0 million for the three months ended March 31, 2020, up from $814,000 for the three months ended March 31, 2019. The increase in G&A expenses resulted primarily from increased non-cash share-based compensation costs.

Total other (income) expense, net, for the three months ended March 31, 2020 was a net expense of $12,000, compared with net income of $178,000 for the three months ended March 31, 2019. The change was primarily caused by the foreign currency transaction losses associated with funds held in non-functional currency (US dollar) accounts, principally Australian dollars. A decrease in R&D incentives, associated with decreased ReMEDy costs and reductions in interest income earned on marketable securities during the three months ended March 31, 2020, also contribute to this change.

Balance Sheet and Cash Flow

The Company had cash, cash equivalents and marketable securities of $12.6 million, current liabilities of $0.9 million and working capital of $13.2 million as of March 31, 2020, compared to $7.9 million in cash, cash equivalents and marketable securities, $1.3 million in current liabilities and $7.5 million in working capital as of December 31, 2019. The increases in the Company’s combined cash, cash equivalents and marketable securities and in its working capital are due primarily to the February 2020 public offering of common shares.

Net cash used in operating activities was $3.0 million for the three months ended March 31, 2020, compared to $3.1 million for the three months ended March 31, 2019. The net cash used in each of these periods primarily reflects the net loss for these periods, offset by non-cash charges for stock-based compensation and adjusted for the net effects of changes in operating assets and liabilities.

About DM199

DM199 is a recombinant (synthetic) form of the human serine protease, KLK1. The KLK1 protein plays an important role in the regulation of diverse physiological processes including blood flow, inflammation, fibrosis, oxidative stress and neurogenesis via a molecular mechanism that increases production of nitric oxide and prostaglandin. KLK1 deficiency may play a role in multiple vascular and fibrotic diseases such as chronic kidney disease, retinopathy, stroke, vascular dementia, and resistant hypertension where current treatment options are limited or ineffective. DiaMedica is the first company to have developed a recombinant form of the KLK1 protein. The KLK1 protein, produced from porcine pancreas and human urine, has been used to treat patients in Japan, China and Korea for decades. DM199 is currently being studied in patients with chronic kidney disease and patients with acute ischemic stroke.
