"KEYTRUDA is the first immunotherapy to significantly extend survival of patients with nonsquamous non-small cell lung cancer in combination with chemotherapy as a first-line treatment, including in patients whose tumors are either PD-L1 negative or are untested," said Dr. Roger M. Perlmutter, president, Merck Research Laboratories. "With this sBLA acceptance by the FDA, we are pleased that data from KEYNOTE-189 is now under review by regulatory authorities in the United States, Europe, and Japan."

This supplemental application is based on overall survival (OS) and progression-free survival (PFS) data from the Phase 3 KEYNOTE-189 trial, which were recently presented at the American Association of Cancer Research (AACR) (Free AACR Whitepaper) 2018 Annual Meeting, and published simultaneously in The New England Journal of Medicine. KEYNOTE-189 is the confirmatory trial for KEYNOTE-021 (Cohort G), a Phase 2 study that made KEYTRUDA the only FDA-approved anti-PD-1 therapy in combination with chemotherapy (pemetrexed plus carboplatin) for the first-line treatment of patients with metastatic nonsquamous NSCLC, regardless of PD-L1 expression. If approved by the FDA, this would mark the third indication for KEYTRUDA in metastatic NSCLC in the United States based on OS data.

Merck has an extensive clinical development program in lung cancer and is advancing multiple registration-enabling studies with KEYTRUDA in combination with other treatments and as monotherapy. The program, which is comprised of nearly 9,000 patients across 15 Merck-sponsored clinical studies, is evaluating KEYTRUDA across multiple settings and stages of the disease.

About Lung Cancer

Lung cancer, which forms in the tissues of the lungs, usually within cells lining the air passages, is the leading cause of cancer death worldwide. Each year, more people die of lung cancer than die of colon, breast and prostate cancers combined. The two main types of lung cancer are non-small cell and small cell. NSCLC is the most common type of lung cancer, accounting for about 85 percent of all cases. The five-year survival rate for patients diagnosed in the United States with any stage of lung cancer is estimated to be 18 percent.

About KEYTRUDA (pembrolizumab) Injection 100mg

KEYTRUDA is an anti-PD-1 therapy that works by increasing the ability of the body’s immune system to help detect and fight tumor cells. KEYTRUDA is a humanized monoclonal antibody that blocks the interaction between PD-1 and its ligands, PD-L1 and PD-L2, thereby activating T lymphocytes which may affect both tumor cells and healthy cells.

Merck has the industry’s largest immuno-oncology clinical research program, which currently involves more than 750 trials studying KEYTRUDA across a wide variety of cancers and treatment settings. The KEYTRUDA clinical program seeks to understand the role of KEYTRUDA across cancers and the factors that may predict a patient’s likelihood of benefitting from treatment with KEYTRUDA, including exploring several different biomarkers.

Selected Important Safety Information for KEYTRUDA

KEYTRUDA can cause immune-mediated pneumonitis, including fatal cases. Pneumonitis occurred in 94 (3.4%) of 2799 patients receiving KEYTRUDA, including Grade 1 (0.8%), 2 (1.3%), 3 (0.9%), 4 (0.3%), and 5 (0.1%) pneumonitis, and occurred more frequently in patients with a history of prior thoracic radiation (6.9%) compared to those without (2.9%). Monitor patients for signs and symptoms of pneumonitis. Evaluate suspected pneumonitis with radiographic imaging. Administer corticosteroids for Grade 2 or greater pneumonitis. Withhold KEYTRUDA for Grade 2; permanently discontinue KEYTRUDA for Grade 3 or 4 or recurrent Grade 2 pneumonitis.

KEYTRUDA can cause immune-mediated colitis. Colitis occurred in 48 (1.7%) of 2799 patients receiving KEYTRUDA, including Grade 2 (0.4%), 3 (1.1%), and 4 (<0.1%) colitis. Monitor patients for signs and symptoms of colitis. Administer corticosteroids for Grade 2 or greater colitis. Withhold KEYTRUDA for Grade 2 or 3; permanently discontinue KEYTRUDA for Grade 4 colitis.

KEYTRUDA can cause immune-mediated hepatitis. Hepatitis occurred in 19 (0.7%) of 2799 patients receiving KEYTRUDA, including Grade 2 (0.1%), 3 (0.4%), and 4 (<0.1%) hepatitis. Monitor patients for changes in liver function. Administer corticosteroids for Grade 2 or greater hepatitis and, based on severity of liver enzyme elevations, withhold or discontinue KEYTRUDA.

KEYTRUDA can cause hypophysitis. Hypophysitis occurred in 17 (0.6%) of 2799 patients receiving KEYTRUDA, including Grade 2 (0.2%), 3 (0.3%), and 4 (<0.1%) hypophysitis. Monitor patients for signs and symptoms of hypophysitis (including hypopituitarism and adrenal insufficiency). Administer corticosteroids and hormone replacement as clinically indicated. Withhold KEYTRUDA for Grade 2; withhold or discontinue for Grade 3 or 4 hypophysitis.

KEYTRUDA can cause thyroid disorders, including hyperthyroidism, hypothyroidism, and thyroiditis. Hyperthyroidism occurred in 96 (3.4%) of 2799 patients receiving KEYTRUDA, including Grade 2 (0.8%) and 3 (0.1%) hyperthyroidism. Hypothyroidism occurred in 237 (8.5%) of 2799 patients receiving KEYTRUDA, including Grade 2 (6.2%) and 3 (0.1%) hypothyroidism. The incidence of new or worsening hypothyroidism was higher in patients with HNSCC, occurring in 28 (15%) of 192 patients with HNSCC, including Grade 3 (0.5%) hypothyroidism. Thyroiditis occurred in 16 (0.6%) of 2799 patients receiving KEYTRUDA, including Grade 2 (0.3%) thyroiditis. Monitor patients for changes in thyroid function (at the start of treatment, periodically during treatment, and as indicated based on clinical evaluation) and for clinical signs and symptoms of thyroid disorders. Administer replacement hormones for hypothyroidism and manage hyperthyroidism with thionamides and beta-blockers as appropriate. Withhold or discontinue KEYTRUDA for Grade 3 or 4 hyperthyroidism.

KEYTRUDA can cause type 1 diabetes mellitus, including diabetic ketoacidosis, which have been reported in 6 (0.2%) of 2799 patients. Monitor patients for hyperglycemia or other signs and symptoms of diabetes. Administer insulin for type 1 diabetes, and withhold KEYTRUDA and administer antihyperglycemics in patients with severe hyperglycemia.

KEYTRUDA can cause immune-mediated nephritis. Nephritis occurred in 9 (0.3%) of 2799 patients receiving KEYTRUDA, including Grade 2 (0.1%), 3 (0.1%), and 4 (<0.1%) nephritis. Monitor patients for changes in renal function. Administer corticosteroids for Grade 2 or greater nephritis. Withhold KEYTRUDA for Grade 2; permanently discontinue KEYTRUDA for Grade 3 or 4 nephritis.

Immune-mediated rashes, including Stevens-Johnson syndrome (SJS), toxic epidermal necrolysis (TEN) (some cases with fatal outcome), exfoliative dermatitis, and bullous pemphigoid, can occur. Monitor patients for suspected severe skin reactions and based on the severity of the adverse reaction, withhold or permanently discontinue KEYTRUDA and administer corticosteroids. For signs or symptoms of SJS or TEN, withhold KEYTRUDA and refer the patient for specialized care for assessment and treatment. If SJS or TEN is confirmed, permanently discontinue KEYTRUDA.

KEYTRUDA can cause other clinically important immune-mediated adverse reactions. These immune-mediated reactions may occur in any organ system. For suspected immune-mediated adverse reactions, ensure adequate evaluation to confirm etiology or exclude other causes. Based on the severity of the adverse reaction, withhold KEYTRUDA and administer corticosteroids. Upon improvement to Grade 1 or less, initiate corticosteroid taper and continue to taper over at least 1 month. Based on limited data from clinical studies in patients whose immune-related adverse reactions could not be controlled with corticosteroid use, administration of other systemic immunosuppressants can be considered. Resume KEYTRUDA when the adverse reaction remains at Grade 1 or less following corticosteroid taper. Permanently discontinue KEYTRUDA for any Grade 3 immune-mediated adverse reaction that recurs and for any life-threatening immune-mediated adverse reaction.

The following clinically significant immune-mediated adverse reactions occurred in less than 1% (unless otherwise indicated) of 2799 patients: arthritis (1.5%), uveitis, myositis, Guillain-Barré syndrome, myasthenia gravis, vasculitis, pancreatitis, hemolytic anemia, and partial seizures arising in a patient with inflammatory foci in brain parenchyma. In addition, myelitis and myocarditis were reported in other clinical trials, including classical Hodgkin lymphoma, and postmarketing use.

Solid organ transplant rejection has been reported in postmarketing use of KEYTRUDA. Treatment with KEYTRUDA may increase the risk of rejection in solid organ transplant recipients. Consider the benefit of treatment with KEYTRUDA vs the risk of possible organ rejection in these patients.

KEYTRUDA can cause severe or life-threatening infusion-related reactions, including hypersensitivity and anaphylaxis, which have been reported in 6 (0.2%) of 2799 patients. Monitor patients for signs and symptoms of infusion-related reactions, including rigors, chills, wheezing, pruritus, flushing, rash, hypotension, hypoxemia, and fever. For Grade 3 or 4 reactions, stop infusion and permanently discontinue KEYTRUDA.

Immune-mediated complications, including fatal events, occurred in patients who underwent allogeneic hematopoietic stem cell transplantation (HSCT) after being treated with KEYTRUDA. Of 23 patients with cHL who proceeded to allogeneic HSCT after treatment with KEYTRUDA on any trial, 6 patients (26%) developed graft-versus-host disease (GVHD), one of which was fatal, and 2 patients (9%) developed severe hepatic veno-occlusive disease (VOD) after reduced-intensity conditioning, one of which was fatal. Cases of fatal hyperacute GVHD after allogeneic HSCT have also been reported in patients with lymphoma who received a PD-1 receptor–blocking antibody before transplantation.

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.

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

Based on its mechanism of action, KEYTRUDA can cause fetal harm when administered to a pregnant woman. If used during pregnancy, or if the patient becomes pregnant during treatment, apprise the patient of the potential hazard to a fetus. Advise females of reproductive potential to use highly effective contraception during treatment and for 4 months after the last dose of KEYTRUDA.

In KEYNOTE-006, KEYTRUDA was discontinued due to adverse reactions in 9% of 555 patients with advanced melanoma; adverse reactions leading to discontinuation in more than one patient were colitis (1.4%), autoimmune hepatitis (0.7%), allergic reaction (0.4%), polyneuropathy (0.4%), and cardiac failure (0.4%). Adverse reactions leading to interruption of KEYTRUDA occurred in 21% of patients; the most common (≥1%) was diarrhea (2.5%). The most common adverse reactions with KEYTRUDA vs ipilimumab were fatigue (28% vs 28%), diarrhea (26% with KEYTRUDA), rash (24% vs 23%), and nausea (21% with KEYTRUDA). Corresponding incidence rates are listed for ipilimumab only for those adverse reactions that occurred at the same or lower rate than with KEYTRUDA.

This study was not designed to demonstrate a statistically significant difference in adverse reaction rates for KEYTRUDA as compared to carbo/pem alone for any specified adverse reaction.

In KEYNOTE-012, KEYTRUDA was discontinued due to adverse reactions in 17% of 192 patients with HNSCC. Serious adverse reactions occurred in 45% of patients. The most frequent serious adverse reactions reported in at least 2% of patients were pneumonia, dyspnea, confusional state, vomiting, pleural effusion, and respiratory failure. The most common adverse reactions (reported in at least 20% of patients) were fatigue, decreased appetite, and dyspnea. Adverse reactions occurring in patients with HNSCC were generally similar to those occurring in patients with melanoma or NSCLC, with the exception of increased incidences of facial edema (10% all Grades; 2.1% Grades 3 or 4) and new or worsening hypothyroidism.

In KEYNOTE-087, KEYTRUDA was discontinued due to adverse reactions in 5% of 210 patients with cHL, and treatment was interrupted due to adverse reactions in 26% of patients. Fifteen percent (15%) of patients had an adverse reaction requiring systemic corticosteroid therapy. Serious adverse reactions occurred in 16% of patients. The most frequent serious adverse reactions (≥1%) included pneumonia, pneumonitis, pyrexia, dyspnea, GVHD, and herpes zoster. Two patients died from causes other than disease progression; one from GVHD after subsequent allogeneic HSCT and one from septic shock.

Serious adverse reactions occurred in 39% of KEYTRUDA-treated patients, the most frequent (≥2%) of which were urinary tract infection, pneumonia, anemia, and pneumonitis.

It is not known whether KEYTRUDA is excreted in human milk. Because many drugs are excreted in human milk, instruct women to discontinue nursing during treatment with KEYTRUDA and for 4 months after the final dose.

There is limited experience in pediatric patients. In a study, 40 pediatric patients (16 children aged 2 years to younger than 12 years and 24 adolescents aged 12 years to 18 years) with advanced melanoma, lymphoma, or PD-L1–positive advanced, relapsed, or refractory solid tumors were administered KEYTRUDA 2 mg/kg every 3 weeks. Patients received KEYTRUDA for a median of 3 doses (range 1–17 doses), with 34 patients (85%) receiving KEYTRUDA for 2 doses or more. The safety profile in these pediatric patients was similar to that seen in adults treated with KEYTRUDA. Toxicities that occurred at a higher rate (≥15% difference) in these patients when compared to adults under 65 years of age were fatigue (45%), vomiting (38%), abdominal pain (28%), hypertransaminasemia (28%), and hyponatremia (18%).

"The ability to activate tumor-fighting immune cells has been a tremendous breakthrough in curing cancer in some patients, but the rate of responses leading to long-term remission and overall survival is still limited. Combination therapies are needed that demonstrate improved efficacy but are safe and convenient for patients. IL-2 has proven activity but limited use due to safety issues," said Laura Shawver, Ph.D., president, CEO, and director of Synthorx. "Our investors immediately recognized the remarkable ability of our lead molecule, Synthorin IL-2, to deliver sustained cancer-killing activity without the safety liability through our unique ability to modify protein therapeutics for tuning receptor pharmacology and extending half-life."

"Since its discovery nearly 40 years ago, IL-2 is the most studied cytokine and potentially the most valuable molecule for boosting the efficacy of immuno-oncology therapies," said Marcos Milla, Ph.D., who was recently promoted to chief scientific officer of Synthorx. "To make the best IL-2 we have seen to date, the scientific team at Synthorx applied the company’s expanded genetic alphabet technology to create specific receptor interactions with great precision that bias IL-2’s activity to immune activation versus repression."

"We are impressed with the data for Synthorin IL-2 and how the Synthorx technology platform can specifically identify and select protein modifications that result in the desired therapeutic effect and pharmacokinetics. It is easy to see how this platform could be applied to a variety of protein therapeutics," said Dr. Thompson.

STUDY OF T CELL MEDIATED IMMUNITY FROM COMBINATION OF PV-10 AND IMMUNE CHECKPOINT BLOCKADE IN MURINE MELANOMA MODELS PUBLISHED IN PLOS ONE

On April 30, 2018 Provectus Biopharmaceuticals, Inc. (OTCQB: PVCT, www.provectusbio.com), ("Provectus" or the "Company"), a clinical-stage biotechnology company developing PV-10 as the first small molecule oncolytic immunotherapy for solid tumor cancers, reported that the open-access journal PLOS ONE published results from an H. Lee Moffitt Cancer Center and Research Institute ("Moffitt") study investigating cancer combination therapy with intralesional ("IL") PV-10 and immune checkpoint blockade (anti-CTLA-4, anti-PD-1 and anti-PD-L1 antibodies) in murine melanoma models.1,2 The authors also examined the role of specific immune cell populations in eliciting and controlling tumor-specific response (Press release, Provectus Pharmaceuticals, APR 30, 2018, View Source [SID1234525865]).

The Moffitt authors noted, "In this study, we have shown the impact of combining systemic checkpoint blockade (PD-1, PD-L1) with the tumor-specific immune response induced by IL PV-10. Treatment with IL PV-10 and anti-PD-1 antibody resulted in a delay in tumor growth and enhanced T cell activation in the M05 tumor model. Similar effects were observed with IL PV-10 and anti-PD-L1 antibody in the B16 tumor model. The effect of combination therapy with IL PV-10 and PD-1 blockade is mediated by CD8+ T cells, and depletion of either CD4+ T cells or CD4+CD25+ Tregs enhances anti-tumor immunity in the M05 melanoma model. Together these results support further development of clinical trials to assess safety and anti-tumor T cell responses in patients after IL injection of PV-10 in combination with checkpoint blockade."

Dominic Rodrigues, Vice Chair of the Company’s Board of Directors, said, "We are grateful to our research collaborators, like those at Moffitt, who continue to independently establish PV-10 as an oncolytic immunotherapy in both monotherapy and combination therapy settings."

Mr. Rodrigues added, "This PLOS ONE work established the rational clinical foundation for our ongoing Phase 1b/2 study PV-10 in combination with anti-PD-1 drug KEYTRUDA for patients with Stage IV melanoma. Moffit’s work also builds on the foundation for future combinations of PV-10 and anti-PD-L1 agents as well as other potential combinations and permutations of cancer therapies that include PV-10 as a key element."

About our Phase 1b/2 Study of PV-10 + KEYTRUDA for Stage IV Melanoma

The Phase 1b portion of the study continues to enroll patients with metastatic melanoma at clinical sites in the U.S. (NCT02557321). Stage IV patients with at least one injectable lesion who are candidates for KEYTRUDA are eligible. A total of up to 24 patients would receive the combination of IL PV-10 and KEYTRUDA every three weeks for five cycles (i.e., for up to 12 weeks, with no further PV-10 administered after week 12), followed by only KEYTRUDA every three weeks for up to 24 months. The primary endpoint for the Phase 1b trial is safety and tolerability; objective response rate and progression-free survival are key secondary endpoints (both assessed via RECIST 1.1 after five treatment cycles, and then every 12 weeks thereafter).
