The presentation was well attended, where James Nathanielsz, the Chief Executive Officer of the Company, discussed recent scientific advancements of its lead product candidate, PRP, and its ability to suppress the cancer stem cell population, which the Company plans to submit for publication to a peer reviewed scientific journal.

"We have demonstrated using both in vitro (cell line) and in vivo (animal) data that PRP effectively suppresses cancer stem cells ("CSCs") by suppressing key genes, which are critical to controlling their population and reducing the risk of tumor recurrence, clinically. Furthermore, we discovered a key gene target for drug developers, Rac1B, which increased as a result of PRP treatment. This gene suppresses cellular motility and proliferation of CSCs by ultimately inhibiting TGF-β, a known growth factor responsible for tumorigenesis and metastasis," said Mr. Nathanielsz. "We remain excited by these important discoveries, as suppressing the CSCs population whilst avoiding potential unwanted side effects towards normal stem cells means we have a targeted therapy that can control the spread of cancer. Metastasis, or spreading cancer, remains the main cause of patient death from cancer."

During the presentation at the conference, Mr. Nathanielsz explained the current anticipated timelines for commencing the Company’s engineering run and full scale GMP manufacturing batch of PRP, emphasising that management’s focus was to identify a suitable source of capital as it prepares for filling its drug product for clinical trials, as well as the goal of reducing the Company’s debt on the balance sheet by increasing equity investment. Management was pleased to receive interest at the conference and is currently looking into potential financing options with its advisors and investment banking team.

In addition, Mr. Nathanielsz met with Zack’s Small Cap Research during the conference, to discuss and evaluate the strength of the Company’s intellectual property portfolio, which management believes is greatly undervalued in comparison to other cancer stem cell companies, taking into consideration the Company’s recent advancements of two patents into national phase (i.e. the approval process for a patent within a jurisdiction from an individual patent office), with a third patent entering national phase in key global regions later this year.

"We wish to assure our shareholders that we are working extremely diligently to identify potential suitable sources of capital to support the growth of the Company, including advancing our lead product, PRP, as well as strengthening our balance sheet, as we look to progress towards commencing a first-in-human study of PRP. Presenting at the NewsMakers Conference was a fantastic opportunity to present to sophisticated healthcare investors managing billions of dollars in their portfolios, who understand the space we’re in, and appreciate the uniqueness of our technology. We will continue to provide shareholder updates as we progress with our goals," continued Mr. Nathanielsz.

The Company’s presentation was filed as an exhibit to the Company’s Current Report on Form 8-K filed with the U.S. Securities and Exchange Commission on September 7, 2018, and is also available on the Company’s website at View Source

"Given the exciting preliminary poziotinib clinical data in NSCLC patients with EGFR exon 20 mutations who have received prior systemic therapy, we are happy to extend our participation in Spectrum’s trial to explore poziotinib’s activity in the first-line setting," said Jonathan Goldman, M.D., Associate Professor of Hematology and Oncology, Associate Director of Drug Development and Director of Clinical Trials in Thoracic Oncology at UCLA Health. "Current available therapies for NSCLC patients with exon 20 insertion mutations have been shown to be minimally effective. We do not have good options for these patients as we do in other settings with actionable mutations. This clinical trial expansion is a welcome milestone for patients and physicians battling this disease."

The poziotinib NSCLC clinical program for patients with EGFR or HER2 exon 20 mutations currently consists of a Phase 2 pivotal, Spectrum-sponsored, multi-center global study (ZENITH20) with active sites in the United States and future centers planned in Canada and Europe, and a Phase 2 investigator-initiated study at the University of Texas MD Anderson Cancer Center. Spectrum’s ZENITH20 study now includes four cohorts, with each cohort being an independent study with pre-specified statistical hypotheses and statistical power. The protocol amendment incorporating the two new cohorts was designed based on input from the FDA. The two previously-treated cohorts will enroll up to 87 patients each, and the two first-line cohorts will enroll up to 70 patients each. For each cohort, the primary endpoint is objective response rate; the secondary endpoints are disease control rate, duration of response, safety and tolerability; and the exploratory endpoints are progression-free survival and quality of life.

About Poziotinib

Poziotinib is a novel, orally administered Epidermal Growth Factor Receptor Tyrosine Kinase Inhibitor (EGFR TKI) that inhibits the tyrosine kinase activity of EGFR (HER1) as well as HER2 and HER4. Importantly, this leads to the inhibition of the proliferation of tumor cells that overexpress these receptors. Mutations or overexpression/amplification of EGFR family receptors have been associated with a number of different cancers, including non-small cell lung cancer (NSCLC), breast cancer and gastric cancer. Spectrum received an exclusive license to develop, manufacture, and commercialize worldwide excluding Korea and China from Hanmi Pharmaceuticals.

FDA Grants Priority Review to Merck’s Application for KEYTRUDA® (pembrolizumab) Monotherapy for First-Line Treatment of Locally Advanced or Metastatic Non-Small Cell Lung Cancer in Patients Whose Tumors Express PD-L1 (TPS ≥1%)

On September 12, 2018 Merck (NYSE: MRK), known as MSD outside the United States and Canada, reported that the U.S. Food and Drug Administration (FDA) has accepted for review and granted priority review to a new supplemental Biologics License Application (sBLA) seeking approval for KEYTRUDA, Merck’s anti-PD-1 therapy, as monotherapy for first-line treatment of locally advanced or metastatic nonsquamous or squamous non-small cell lung cancer (NSCLC) in patients whose tumors express PD-L1 (tumor proportion score [TPS] ≥1%) without EGFR or ALK genomic tumor aberrations (Press release, Merck & Co, SEPT 12, 2018, View Source [SID1234529402]). The application is based on data from the pivotal Phase 3 KEYNOTE-042 trial, one of five Phase 3 clinical trials with KEYTRUDA in NSCLC to demonstrate a significant improvement in overall survival. Data from the trial were presented earlier this year at the 2018 American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Annual Meeting. The FDA has set a Prescription Drug User Fee Act (PDUFA), or target action, date of Jan. 11, 2019.

"KEYTRUDA is already a foundation for the treatment of metastatic non-small cell lung cancer," said Dr. Roy Baynes, Senior Vice President and Head of Global Clinical Development, Chief Medical Officer, Merck Research Laboratories. "We are pleased that the FDA is reviewing this sBLA and we look forward to potentially extending the monotherapy indication for KEYTRUDA to locally advanced or metastatic patients whose tumors express PD-L1, with a tumor proportion score of one percent or more."

In addition to KEYNOTE-042, Merck’s leading lung cancer clinical development program includes 10 Phase 3 trials with KEYTRUDA in combination with other treatments and as monotherapy across histologies and lines of treatment in both advanced and earlier stages of 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. There are currently more than 800 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

Immune-Mediated Pneumonitis

KEYTRUDA can cause immune-mediated pneumonitis, including fatal cases. Pneumonitis occurred in 3.4% (94/2799) of patients receiving KEYTRUDA, including Grade 1 (0.8%), 2 (1.3%), 3 (0.9%), 4 (0.3%), and 5 (0.1%), 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 for Grade 3 or 4 or recurrent Grade 2 pneumonitis.

Immune-Mediated Colitis

KEYTRUDA can cause immune-mediated colitis. Colitis occurred in 1.7% (48/2799) of patients receiving KEYTRUDA, including Grade 2 (0.4%), 3 (1.1%), and 4 (<0.1%). 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 for Grade 4 colitis.

Immune-Mediated Hepatitis

KEYTRUDA can cause immune-mediated hepatitis. Hepatitis occurred in 0.7% (19/2799) of patients receiving KEYTRUDA, including Grade 2 (0.1%), 3 (0.4%), and 4 (<0.1%). 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.

Immune-Mediated Endocrinopathies

KEYTRUDA can cause hypophysitis, thyroid disorders, and type 1 diabetes mellitus. Hypophysitis occurred in 0.6% (17/2799) of patients, including Grade 2 (0.2%), 3 (0.3%), and 4 (<0.1%). Hypothyroidism occurred in 8.5% (237/2799) of patients, including Grade 2 (6.2%) and 3 (0.1%). The incidence of new or worsening hypothyroidism was higher in patients with HNSCC occurring in 15% (28/192) of patients. Hyperthyroidism occurred in 3.4% (96/2799) of patients, including Grade 2 (0.8%) and 3 (0.1%), and thyroiditis occurred in 0.6% (16/2799) of patients, including Grade 2 (0.3%). Type 1 diabetes mellitus, including diabetic ketoacidosis, occurred in 0.2% (6/2799) of patients.

Monitor patients for signs and symptoms of hypophysitis (including hypopituitarism and adrenal insufficiency), thyroid function (prior to and periodically during treatment), and hyperglycemia. For hypophysitis, administer corticosteroids and hormone replacement as clinically indicated. Withhold KEYTRUDA for Grade 2 and withhold or discontinue for Grade 3 or 4 hypophysitis. Administer hormone replacement for hypothyroidism and manage hyperthyroidism with thionamides and beta-blockers as appropriate. Withhold or discontinue KEYTRUDA for Grade 3 or 4 hyperthyroidism. Administer insulin for type 1 diabetes, and withhold KEYTRUDA and administer anti-hyperglycemics in patients with severe hyperglycemia.

Immune-Mediated Nephritis and Renal Dysfunction

KEYTRUDA can cause immune-mediated nephritis. Nephritis occurred in 0.3% (9/2799) of patients receiving KEYTRUDA, including Grade 2 (0.1%), 3 (0.1%), and 4 (<0.1%) nephritis. Nephritis occurred in 1.7% (7/405) of patients receiving KEYTRUDA in combination with pemetrexed and platinum chemotherapy. Monitor patients for changes in renal function. Administer corticosteroids for Grade 2 or greater nephritis. Withhold KEYTRUDA for Grade 2; permanently discontinue for Grade 3 or 4 nephritis.

Immune-Mediated Skin Reactions

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.

Other Immune-Mediated Adverse Reactions

Immune-mediated adverse reactions, which may be severe or fatal, can occur in any organ system or tissue in patients receiving KEYTRUDA and may also occur after discontinuation of treatment. 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, sarcoidosis, and encephalitis. In addition, myelitis and myocarditis were reported in other clinical trials and postmarketing use.

Treatment with KEYTRUDA may increase the risk of rejection in solid organ transplant recipients. Consider the benefit of treatment vs the risk of possible organ rejection in these patients.

Infusion-Related Reactions

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

Complications of Allogenic Hematopoietic Stem Cell Transplantation (HSCT)

Immune-mediated complications, including fatal events, occurred in patients who underwent allogeneic HSCT after treatment with KEYTRUDA. Of 23 patients with cHL who proceeded to allogeneic HSCT after KEYTRUDA, 6 developed graft-versus-host disease (GVHD) (one fatal case) and 2 developed severe hepatic veno-occlusive disease (VOD) after reduced-intensity conditioning (one fatal case). 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. Follow patients closely for early evidence of transplant-related complications such as hyperacute graft-versus-host disease (GVHD), Grade 3 to 4 acute GVHD, steroid-requiring febrile syndrome, hepatic veno-occlusive disease (VOD), and other immune-mediated adverse reactions.

In patients with a history of allogeneic HSCT, acute GVHD (including fatal GVHD), has been reported after treatment with KEYTRUDA. Patients who experienced GVHD after their transplant procedure may be at increased risk for GVHD after KEYTRUDA. Consider the benefit of KEYTRUDA vs the risk of GVHD in these patients.

Increased Mortality in Patients with Multiple Myeloma

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.

Embryofetal Toxicity

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.

The most common adverse reactions (≥20%) in patients who received KEYTRUDA were fatigue (38%), musculoskeletal pain (32%), pruritus (23%), decreased appetite (21%), nausea (21%), and rash (20%).

In KEYNOTE-158, KEYTRUDA was discontinued due to adverse reactions in 8% of 98 patients with recurrent or metastatic cervical cancer. Serious adverse reactions occurred in 39% of patients receiving KEYTRUDA; the most frequent included anemia (7%), fistula, hemorrhage, and infections [except urinary tract infections] (4.1% each). The most common adverse reactions (≥20%) were fatigue (43%), musculoskeletal pain (27%), diarrhea (23%), pain and abdominal pain (22% each), and decreased appetite (21%).

Lactation

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.

Pediatric Use

There is limited experience in pediatric patients. In a study in 40 pediatric patients with advanced melanoma, lymphoma, or PD-L1–positive advanced, relapsed, or refractory solid tumors, the safety profile 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%).

Incyte and Foundation Medicine Announce Agreement to Develop Companion Diagnostic for Pemigatinib (INCB54828), a Selective FGFR Inhibitor, in Patients with Cholangiocarcinoma

On September 11, 2018 Incyte Corporation (NASDAQ:INCY) and Foundation Medicine, Inc., reported that the companies have entered into an agreement for the development, regulatory support and commercialization of companion diagnostics (CDx), with an initial focus on CDx development for pemigatinib (INCB54828), Incyte’s selective FGFR1/2/3 inhibitor, in patients with cholangiocarcinoma (Press release, Incyte, SEP 11, 2018, View Source [SID1234529610]). The initial CDx, which will include detection of activating FGFR2 translocations, is expected to be incorporated into FoundationOneCDx, Foundation Medicine’s FDA-approved comprehensive genomic profiling (CGP) assay and broad CDx platform.

"There is an urgent need for a novel, biomarker-based, targeted therapeutic approach for patients with cholangiocarcinoma. The initial goal of this collaboration is to develop a companion diagnostic to enable testing at diagnosis of stage IV disease, with the aim of helping to reduce morbidity and mortality, and we are very pleased to be working with Foundation Medicine as we seek to improve outcomes for these patients," said Steven Stein, M.D., Chief Medical Officer, Incyte. "Incyte is evaluating pemigatinib in patients with cholangiocarcinoma as part of the FIGHT clinical development program; initial data have been accepted for presentation at the European Society of Medical Oncology (ESMO) (Free ESMO Whitepaper) meeting in Munich this October."

"We’re committed to helping our biopharma partners bring biomarker-driven therapies to cancer patients. Partnerships with innovative biopharma companies, such as Incyte, who leverage our FDA-approved platform to help accelerate companion diagnostics development, are essential to achieving this mission," said Melanie Nallicheri, Chief Business Officer and Head of Biopharma at Foundation Medicine. "We’re proud to partner with Incyte to advance development of a potential new precision oncology treatment option for cholangiocarcinoma."

About FGFR and Pemigatinib (INCB54828)

Fibroblast growth factor receptors (FGFRs) play an important role in tumor cell proliferation and survival, migration and angiogenesis (the formation of new blood vessels). Activating mutations, translocations and gene amplifications in FGFRs are closely correlated with the development of various cancers.

Pemigatinib is a potent, selective, oral inhibitor of FGFR isoforms 1, 2 and 3 which, in preclinical studies, has demonstrated selective pharmacologic activity against cancer cells with FGFR alterations. Phase 2 studies investigating the safety and efficacy of pemigatinib monotherapy across several FGFR-driven malignancies are ongoing—the FIGHT (FIbroblast Growth factor receptor in oncology and Hematology Trials) clinical trial program currently comprises FIGHT-201 in patients with metastatic or surgically unresectable bladder cancer, including with activating FGFR3 alterations; FIGHT-202 in patients with metastatic or surgically unresectable cholangiocarcinoma who have failed previous therapy, including with activating FGFR2 translocations; and FIGHT-203 in patients with myeloproliferative neoplasms with activating FGFR1 translocations.
