The Australian government established this tax incentive program to stimulate local industry investment in R&D by offering businesses tax offsets for eligible R&D expenditures made in Australia. OncoSec previously established a subsidiary in Australia and is conducting a portion of both of its TAVO KEYNOTE clinical trials as well as other R&D activities in the region. This work enables OncoSec to qualify for the program and obtain reimbursement for certain expenditures.

"We are always looking for ways to obtain non-dilutive sources of capital for OncoSec," said Daniel J. O’Connor, President and CEO of OncoSec Medical Incorporated. "In addition to leveraging the Australian R&D incentive through our Australian subsidiary, we also relocated our corporate headquarters to New Jersey from San Diego to capitalize on New Jersey’s tax incentive program for local businesses, which qualified OncoSec to receive approximately $875,000 for 2019 R&D work. Combined with the Australian payment, that’s over $1.7 million in non-dilutive capital for OncoSec for R&D work done in 2019. We will use this cash to fund our ongoing TAVO clinical development programs this year, including our pivotal KEYNOTE-695 study in checkpoint resistant metastatic melanoma. We will continue to participate in both the Australian and New Jersey R&D tax incentive programs, as well as pursue any and all opportunities that maximize value for OncoSec shareholders."

"HCC is an aggressive disease in need of different treatment approaches,"4,5,6 said Anthony B. El-Khoueiry, M.D., lead investigator and associate professor of clinical medicine and phase I program director at the Keck School of Medicine, University of Southern California (USC) and the USC Norris Comprehensive Cancer Center. "The overall response rate observed in the Opdivo + Yervoy cohort of the CheckMate -040 trial underscores the potential of this dual immunotherapy as a possible treatment option for patients."1

In the CheckMate -040 cohort of HCC patients previously treated with sorafenib, after a minimum follow up of 28 months,1 33% (16/49; 95% CI: 20-48) of patients responded to treatment with Opdivo + Yervoy; 8% (4/49) had a complete response (CR) and 24% (12/49) had a partial response (PR).1 Duration of responses (DOR) ranged from 4.6 to 30.5+ months, with 88% lasting at least six months, 56% at least 12 months and 31% at least 24 months.1 Overall response rate (ORR) and DOR were assessed by Blinded Independent Central Review (BICR) using Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST v1.1).1 ORR assessed by BICR using modified RECIST was 35% (17/49; 95% CI: 22-50), with a CR reported in 12% (6/49) of patients and a PR reported in 22% (11/49) of patients.1

Opdivo is associated with the following Warnings and Precautions including immune-mediated: pneumonitis, colitis, hepatitis, endocrinopathies, nephritis and renal dysfunction, skin adverse reactions, encephalitis, other adverse reactions; infusion-related reactions; embryo-fetal toxicity; and increased mortality in patients with multiple myeloma when Opdivo is added to a thalidomide analogue and dexamethasone, which is not recommended outside of controlled clinical trials.1 Please see the Important Safety Information section below, including Boxed WARNING for Yervoy (ipilimumab) regarding immune-mediated adverse reactions, as well as select safety information from CheckMate -040.

"The incidence of liver cancer is rising in the United States, and HCC is the most common and aggressive form of the disease,"4,5,6,7,8,9 said Andrea Wilson, president and founder, Blue Faery: The Adrienne Wilson Liver Cancer Association. "Today’s approval provides a new option for patients with HCC previously treated with sorafenib, giving the community more hope."1

Opdivo + Yervoy is the only dual immunotherapy approved by the FDA in this setting. The therapy features a potentially synergistic mechanism of action that targets two different checkpoints (PD-1 and CTLA-4) and works in complementary ways.1

"We recognize there is a critical need to provide patients with aggressive forms of cancer, like HCC, new treatment options that may offer clinically meaningful and ultimately durable responses," said Adam Lenkowsky, general manager and head, U.S., Oncology, Immunology, Cardiovascular, Bristol Myers Squibb. "Today’s announcement builds on our legacy in pioneering immunotherapy treatments and is an important step in our commitment to transforming patients’ lives through science."

Opdivo + Yervoy was granted Breakthrough Therapy Designation for this indication and a Priority Review from the FDA.

About the CheckMate -040 Trial Design

CheckMate -040 (NCT01658878) is a Phase 1/2 open-label study that included a cohort of patients with HCC who progressed on or were intolerant to sorafenib and received Opdivo + Yervoy.1,10 The trial included patients who were PD-L1 expressors and non-expressors.3 Key eligibility criteria included histologic confirmation of HCC and Child-Pugh Class A cirrhosis status.1 Additional eligibility criteria included those who were infected with active HCV or active HBV, or were uninfected.1,3 Patients with active autoimmune disease, brain metastasis, a history of hepatic encephalopathy, clinically significant ascites, infection with HIV, or active co-infection with HBV and HCV or HBV and HDV were excluded.1 Patients with known fibrolamellar HCC, sarcomatoid HCC, and mixed cholangiocarcinoma and HCC were also excluded.3 A total of 49 patients were treated with Opdivo 1 mg/kg IV and Yervoy 3 mg/kg IV every three weeks for four doses, followed by Opdivo 240 mg every two weeks until disease progression or unacceptable toxicity.1 The major efficacy outcome was ORR, as assessed by BICR using RECIST v1.1 and mRECIST.1 Duration of response was also assessed.1

Select Safety Profile from CheckMate -040 Study

The safety of Opdivo 1 mg/kg and Yervoy 3 mg/kg was evaluated in 49 patients.1 Serious adverse reactions occurred in 59% of patients receiving Opdivo + Yervoy.1 Treatment was discontinued in 29% of patients and delayed in 65% of patients for an adverse reaction.1 Serious adverse reactions reported in ≥4% of patients were pyrexia, diarrhea, anemia, increased AST, adrenal insufficiency, ascites, esophageal varices hemorrhage, hyponatremia, increased blood bilirubin, and pneumonitis.1 The most common adverse reactions (reported in ≥20% of patients) were rash (53%), pruritus (53%), musculoskeletal pain (41%), diarrhea (39%), cough (37%), decreased appetite (35%), fatigue (27%), pyrexia (27%), abdominal pain (22%), headache (22%), nausea (20%), dizziness (20%), hypothyroidism (20%), and weight decreased (20%).1

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.

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%). In Checkmate 214, serious adverse reactions occurred in 59% of patients receiving OPDIVO plus YERVOY. The most frequent serious adverse reactions reported in ≥2% of patients were diarrhea, pyrexia, pneumonia, pneumonitis, hypophysitis, acute kidney injury, dyspnea, adrenal insufficiency, and colitis. In Checkmate 142 in MSI-H/dMMR mCRC patients receiving OPDIVO with YERVOY, serious adverse reactions occurred in 47% of patients. The most frequent serious adverse reactions reported in ≥2% of patients were colitis/diarrhea, hepatic events, abdominal pain, acute kidney injury, pyrexia, and dehydration. In Checkmate 040, serious adverse reactions occurred in 59% of patients receiving OPDIVO with YERVOY (n=49). Serious adverse reactions reported in ≥4% of patients were pyrexia, diarrhea, anemia, increased AST, adrenal insufficiency, ascites, esophageal varices hemorrhage, hyponatremia, increased blood bilirubin, and pneumonitis.

AskAt Review Article Presenting EP4 Antagonist’s Mechanism of Action in Cancer Immunotherapy Published in Leading Scientific Journal

On March 11, 2020 AskAt’s reported Frontiers in Immunology, an international scientific journal focusing on immunology, cancer immunity and immunotherapy, has published review article describing a mechanism of anti-tumor action of the EP4 antagonist (Press release, AskAt, MAR 11, 2020, View Source [SID1234555398]). The review is based on immuno-oncological evidence recently published in scientific journals. It suggests a new concept for the mechanism of action of the EP4 antagonist, in combination with a cancer-immunity cycle theory, demonstrating a position for the therapy within current cancer immunotherapy. This new concept helps to advance understanding of AskAt’s EP4 antagonists, AAT-007 and AAT-008, in cancer immunotherapy, and provides an immunological background of EP4 antagonist therapy in combination with immune checkpoint inhibitors, chemotherapy, and tumor radiotherapy. Currently, AAT-007 and AAT-008 are being developed in the U.S. and China, initially targeting colorectal cancer and non-small cell lung cancer.
