U.S. Indication and Important Safety Information About Axumin

INDICATION

Axumin (fluciclovine F 18) injection is indicated for positron emission tomography (PET) imaging in men with suspected prostate cancer recurrence based on elevated blood prostate specific antigen (PSA) levels following prior treatment.

IMPORTANT SAFETY INFORMATION

Image interpretation errors can occur with Axumin PET imaging. A negative image does not rule out recurrent prostate cancer and a positive image does not confirm its presence. The performance of Axumin seems to be affected by PSA levels. Axumin uptake may occur with other cancers and benign prostatic hypertrophy in primary prostate cancer. Clinical correlation, which may include histopathological evaluation, is recommended.
Hypersensitivity reactions, including anaphylaxis, may occur in patients who receive Axumin. Emergency resuscitation equipment and personnel should be immediately available.
Axumin use contributes to a patient’s overall long-term cumulative radiation exposure, which is associated with an increased risk of cancer. Safe handling practices should be used to minimize radiation exposure to the patient and health care providers.
Adverse reactions were reported in ≤ 1% of subjects during clinical studies with Axumin. The most common adverse reactions were injection site pain, injection site erythema and dysgeusia.
To report suspected adverse reactions to Axumin, call 1-855-AXUMIN1 (1-855-298-6461) or contact FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.

Full Axumin prescribing information is available at www.axumin.com.

About Axumin (fluciclovine F 18)

Axumin (fluciclovine F 18) injection is a novel product indicated for use in positron emission tomography (PET) imaging to identify suspected sites of prostate cancer recurrence in men. Recurrence of prostate cancer is suspected by an increase in prostate specific antigen (PSA) levels following prior treatment. PET imaging with Axumin may identify the location and extent of such recurrence. Axumin was developed to enable visualization of the increased amino acid transport that occurs in many cancers, including prostate cancer. It consists of a synthetic amino acid that is preferentially taken up by prostate cancer cells compared with surrounding normal tissues, and is labeled with the radioisotope F 18 for PET imaging. Fluciclovine F 18 was invented at Emory University in Atlanta, Ga., with much of the fundamental clinical development work carried out by physicians at Emory University’s Department of Radiology and Imaging Sciences. Axumin was approved by the U.S. Food and Drug Administration in May 2016, following Priority Review, and is the first product commercialized by Blue Earth Diagnostics, which licensed the product from GE Healthcare. The molecule is being investigated by Blue Earth Diagnostics for other potential cancer indications, such as glioma.

On February 6, 2019 Corvus Pharmaceuticals, Inc. (Nasdaq: CRVS), a clinical-stage biopharmaceutical company focused on the development and commercialization of precisely targeted oncology therapies, reported the presentation of updated biomarker and clinical results from its two lead programs that target the adenosine pathway, CPI-444, an adenosine A2A receptor antagonist, and CPI-006, an anti-CD73 antibody (Press release, Corvus Pharmaceuticals, FEB 6, 2019, View Source [SID1234533117]). The data were presented by Stephen Willingham, Ph.D., Senior Scientist at Corvus, at the Immuno-Oncology 360° Conference in New York during the "Discovery & Preclinical Science Plenary" session, which focused on tumor microenvironment changing technologies, pegylated cytokines and additional discovery and preclinical data.

Key CPI-444 Biomarker Results
Dr. Willingham’s presentation, titled "Blockade of the Adenosine Pathway: Preclinical, Translational and Clinical Studies with CPI-444, an A2A Receptor Antagonist for Cancer Treatment," reviewed gene expression data of an adenosine gene signature recently announced by Corvus (or AdenoSig), in patients with renal cell carcinoma (RCC) who are participating in Corvus’ ongoing Phase 1/1b study of CPI-444, a selective and potent inhibitor of the adenosine A2A receptor. In particular, the data from the study showed a relationship of this novel biomarker to angiogenesis gene expression data (or angiogenesis signature). Such findings indicate that expression of AdenoSig was inversely related to the angiogenesis signature, which has been well studied by others and correlates with response to vascular endothelial growth factor receptor (VEGFR) inhibitors such as Sutent (sunitib malate) and other tyrosine kinase inhibitors. Low expression of angiogenesis genes predicts a lack of response to VEGFR inhibition. These data suggest that patients with a high AdenoSig are potentially more likely to respond to treatment with CPI-444 and less likely to respond to VEGFR inhibitors.

"Based on these translational data, we expect that we may be able to use the AdenoSig as a predictive biomarker to identify patients for adenosine pathway inhibition and select patients for future trials of CPI-444," said Dr. Willingham. "The gene expression data also may enable us to select the optimum patients for combination therapy with CPI-006, our anti-CD73 antibody, which has demonstrated unique immunologic activity in early clinical trials."

Key CPI-006 Clinical Results
Dr. Willingham also presented updated clinical results from the ongoing Phase 1/1b dose-escalation study of CPI-006 in patients with a variety of advanced cancers, including non-small cell lung cancer (NSCLC), RCC and other cancers who have failed standard therapies. The first arm of the study is evaluating CPI-006 as a monotherapy, a second arm is evaluating CPI-006 in combination with CPI-444, and a third arm is planned to evaluate CPI-006 in combination with pembrolizumab, an anti-PD-1 antibody. In particular, the updated results demonstrated that:

CPI-006 given as a monotherapy activated B cells and led to a redistribution of these cells along with changes in other immune cells (e.g., changes in T helper to T suppressor ratios). These data are consistent with immune stimulation induced by CPI-006.
CPI-006 reacted with an epitope on CD73 that led to blockade of adenosine production and expression of lymphocyte activation antigens that are independent of adenosine.
"We continue to advance our two lead therapeutic programs that target the adenosine-cancer pathway. We believe we are well positioned for a potential pivotal trial of CPI-444 in renal cell carcinoma and other tumors based on the biomarker signature we discovered, and CPI-006 is beginning to show early signs of immunologic activity that may be important in cancer therapy," said Richard A. Miller, M.D., an oncologist and co-founder, president and chief executive officer of Corvus. "Regarding our third pipeline program, we anticipate starting a Phase 1/1b trial of CPI-818, an ITK inhibitor for T-cell lymphoma, during the first quarter of 2019."

About CD73 and Adenosine
CD73 is a cell surface enzyme whose function is to convert adenosine monophosphate (AMP) to adenosine by removing phosphate from AMP. CD73 is expressed on cells of the immune system, including T-cells and B-cells. CD73 is also present on many tumors, including lung, renal, melanoma, colon, prostate, breast and others. In the tumor microenvironment, CD73 produces adenosine, which binds to the adenosine A2A receptor on immune cells and inhibits various immune responses including those directed against the tumor. Tumors utilize this immunosuppressive mechanism to escape attack by the immune system.

About CPI-006
CPI-006 is a potent humanized monoclonal antibody that reacts with the active site of CD73, blocking the conversion of AMP to adenosine. In vitro studies of CPI-006 have shown it is capable of substantially inhibiting the production of adenosine by blocking the CD73 enzyme and leads to activation of peripheral blood B cells.

About CPI-444
CPI-444 is a small molecule, oral, checkpoint inhibitor designed to disable a tumor’s ability to subvert attack by the immune system by blocking the binding of adenosine in the tumor microenvironment to the A2A receptor. Adenosine, a metabolite of ATP (adenosine tri-phosphate), is produced within the tumor microenvironment where it may bind to the adenosine A2A receptor present on immune cells and block their activity. CD39 and CD73 are enzymes on the surface of tumor cells and immune cells. These enzymes work in concert to convert ATP to adenosine. In vitro and preclinical studies have shown that dual blockade of CD73 and the A2A receptor may be synergistic.

On February 5, 2019 Sanofi reported that the pivotal Phase 3 trial of isatuximab in patients with relapsed/refractory multiple myeloma met the primary endpoint of prolonging progression free survival in patients treated with isatuximab in combination with pomalidomide and low-dose dexamethasone versus pomalidomide and low-dose dexamethasone alone (standard of care) (Press release, Sanofi, FEB 5, 2019, View Source [SID1234533065]).

Results will be submitted to an upcoming medical meeting and are anticipated to form the basis of regulatory submissions planned for later this year.

"We are excited by these results, which represent significant progress in our ambition to extend the lives of multiple myeloma patients," said John Reed, Head of Research and Development at Sanofi. "We look forward to engaging with regulatory authorities with the goal of bringing this potential new treatment to patients as quickly as possible."

Multiple myeloma is the second most common hematologic malignancy[1], with more than 138,0002 new cases worldwide each year. Multiple myeloma remains incurable in the vast majority of patients, resulting in significant disease burden.

The randomized, multi-center, open label Phase 3 study, known as ICARIA-MM, enrolled 307 patients with relapsed/refractory multiple myeloma across 96 centers spanning 24 countries. All study participants received two or more prior anti-myeloma therapies, including at least two consecutive cycles of lenalidomide and a proteasome inhibitor given alone or in combination. During the trial, isatuximab was administered through an intravenous infusion at a dose of 10mg/kg once weekly for four weeks, then every other week for 28-day cycles in combination with standard doses of pomalidomide and dexamethasone for the duration of treatment. The safety profile was evaluated as a secondary endpoint.

About isatuximab clinical development program

Isatuximab targets a specific epitope of CD38 capable of triggering multiple, distinct mechanisms of action that are believed to promote programmed tumor cell death (apoptosis) and immunomodulatory activity. CD38 is highly and uniformly expressed on multiple myeloma cells and is a cell surface receptor target for antibody-based therapeutics in multiple myeloma and other malignancies. The clinical significance of these findings is under investigation.

ICARIA-MM is one of four ongoing Phase 3 clinical trials evaluating isatuximab in combination with currently available standard treatments for people with relapsed/refractory or newly-diagnosed multiple myeloma.

Isatuximab received orphan designation for relapsed/refractory multiple myeloma by the U.S. Food and Drug Administration and the European Medicines Agency. Isatuximab is an investigational agent and the safety and efficacy has not been evaluated by the U.S. Food and Drug Administration, the European Medicines Agency, or any other regulatory authority. Isatuximab is also under investigation for the treatment of other hematologic malignancies and solid tumors.

On February 5, 2019 Roche (SIX: RO, ROG; OTCQX: RHHBY) reported completing the submission of a supplemental Biologics License Application to the US Food and Drug Administration (FDA) for Kadcyla (trastuzumab emtansine) for adjuvant (after surgery) treatment of people with HER2-positive early breast cancer (eBC) with residual disease after neoadjuvant (before surgery) treatment (Press release, Hoffmann-La Roche, FEB 5, 2019, View Source [SID1234533047]). The FDA is reviewing the application under the Real-Time Oncology Review and Assessment Aid pilot programmes, which aim to explore a more efficient review process to ensure safe and effective treatments are available to patients as early as possible.[1,2] For this indication, Kadcyla was also granted Breakthrough Therapy Designation, which is designed to expedite the development and review of medicines intended to treat serious or life-threatening diseases.[3]

"Kadcyla was granted Breakthrough Therapy Designation and is also the first Roche medicine to be reviewed under the FDA’s Real-Time Oncology Review pilot programme; both FDA initiatives aim to expedite reviews and bring medicines to patients sooner" said Sandra Horning, MD, Roche’s Chief Medical Officer and Head of Global Product Development. "We are working closely with the FDA to bring Kadcyla to people with HER2-positive early breast cancer who have residual disease after neoadjuvant therapy as early as possible."

This application is based on results of the phase III KATHERINE study showing Kadcyla significantly reduced the risk of invasive breast cancer recurrence or death from any cause (invasive disease-free survival; iDFS) by 50% (HR=0.50, 95% CI 0.39-0.64, p<0.0001) compared to Herceptin (trastuzumab) as an adjuvant treatment in people with HER2-positive eBC who have residual disease present following neoadjuvant treatment.[4] People who have residual disease after neoadjuvant treatment have a worse prognosis than those with no detectable disease. At three years, 88.3% of people treated with Kadcyla did not have their breast cancer return compared to 77.0% treated with Herceptin, an absolute improvement of 11.3%.[4]

The most common Grade 3-4 side effects (>1%) with Kadcyla in the KATHERINE study were decreased platelet count; high blood pressure; radiation-induced skin injury; numbness, tingling or pain in the hands or feet; decreased neutrophil count; low blood potassium level; fatigue and decrease in red blood cells.[4]

About the KATHERINE study[5]
KATHERINE is an international, multi-centre, two-arm, randomised, open-label, phase III study evaluating the efficacy and safety of Kadcyla versus Herceptin as an adjuvant therapy in people with HER2-positive eBC who have pathological invasive residual disease in the breast and/or axillary lymph nodes following neoadjuvant therapy that included Herceptin and taxane-based chemotherapy. The primary endpoint of the study is iDFS, which in this study is defined as the time from randomisation free from invasive breast cancer recurrence or death from any cause. Secondary endpoints include disease-free survival and overall survival.

About Kadcyla
Kadcyla is an antibody-drug conjugate (ADC) engineered to deliver potent chemotherapy directly to HER2-positive cancer cells, potentially limiting damage to healthy tissues.[6,7] It combines two anti-cancer properties joined together by a stable linker: the HER2-targeting properties of trastuzumab (the active ingredient in Herceptin) and the chemotherapy agent DM1.[8] Kadcyla is the only ADC approved as a single agent in 104 countries including the US and EU for the treatment of people with HER2-positive metastatic breast cancer who have previously received Herceptin and taxane chemotherapy, separately or in combination. Roche licenses technology for Kadcyla under an agreement with ImmunoGen, Inc.

About Roche’s medicines for HER2-positive breast cancer
Roche has been leading research into the HER2 pathway for over 30 years and is committed to improving the health, quality of life and survival of people with both early and advanced HER2-positive disease. HER2-positive breast cancer is a particularly aggressive form of the disease that affects approximately 15-20% of patients.[9] Roche has developed three innovative medicines that have helped transform the treatment of HER2-positive breast cancer: Herceptin (trastuzumab), Perjeta (pertuzumab) and Kadcyla (trastuzumab emtansine). Eligibility for treatment with Roche’s HER2-targeted medicines is determined via a diagnostic test, which identifies people who will likely benefit from these medicines at the onset of their disease.
