In the first, Alexander M.M. Eggermont, Director General of the Gustave Roussy Cancer Campus Grand Paris in Villejuif, France, and investigators from 23 countries across the world, found that giving a one-year course of 18 doses of the immunotherapy drug pembrolizumab (Keytruda) significantly reduced the risk of the cancer returning for patients with stage III melanoma who were at high risk of recurrence after surgery (Press release, EORTC, APR 16, 2018, View Source [SID1234525394]). Patients with stage III melanoma have metastatic disease in one or more regional lymph nodes. Giving a dose of 200 milligrams of pembrolizumab every three weeks after surgery for up to a year significantly reduced the risk of recurrence for these patients the investigators found.

Pembrolizumab works by blocking a protective mechanism of cancer cells, thus allowing the immune system to destroy them. Of the 1,019 patients recruited to the double-blind trial, 514 were randomised to pembrolizumab, and the others to placebo. For all those randomised to pembrolizumab, the 12-month recurrence-free survival rate was 75.4 percent, compared with 61.0 percent for all those randomised to placebo. The estimated hazard ratio was 0.57, indicating that risk of recurrence or death was reduced by 43 percent in patients randomised to pembrolizumab as compared to those randomised to placebo.

After a median follow-up of 1.25 years, 135 of the 514 patients randomised to pembrolizumab and 216 of the 505 patients randomised to placebo had been diagnosed with recurrent disease or had died. Patients randomised to placebo who had recurrence were offered access to pembrolizumab. "This cross-over design is unique in the world of adjuvant trials in melanoma and will permit us to analyse if adjuvant therapy with pembrolizumab right after surgery is better or not than treating only those who relapse and start treatment at relapse," says Eggermont. "We hope that these data will lead to regulators in the United States and Europe approving pembrolizumab as a new treatment option for these patients."
The trial results are published in the New England Journal of Medicine.

In the second trial, investigators from eight European countries, headed by Patrick Schöffski from KU Leuven, Belgium, found that treatment with a targeted cancer drug achieved complete or partial tumour shrinkage in 50% of patients with inflammatory myofibrobastic tumour (IMFT), a very rare type of soft tissue sarcoma. Soft tissue sarcomas in themselves are very rare, accounting for just 1% of all solid tumour diagnoses, and IMFT so uncommon that there are no reliable statistics for its incidence or for mortality rates.
Many IFMTs have rearrangements of the ALK gene. Recently discovered as a target for cancer therapies, the ALK gene can be oncogenic in three ways – by forming a fusion gene with any of several other genes, by gaining additional copies or through mutations of the actual DNA code for the gene itself.
Schöffski and colleagues therefore set out to see whether the ALK inhibitor crizotinib might be a potential treatment for patients with IMFT. "Inflammatory myofibroblastic tumours are usually resistant to conventional chemotherapy and radiotherapy, so patients with unresectable or locally recurring disease have few treatment options," he says.
Because IMFT is so rare, only 35 patients with a local diagnosis of inflammatory myofibroblastic tumour could be recruited to the trial. Twenty of these patients were confirmed centrally to have the disease and received crizotinib.
Nineteen patients were evaluable for response. The objective response rate among the 12 evaluable patients with ALK-positive IFMTs who received crizotinib was 50 percent (95% confidence interval : 21.1-78.9%); two had a confirmed complete response and four had a confirmed partial response. Among the seven evaluable patients with ALK-negative IFMTs, the rate was 14.3 percent (95% confidence interval: 0.0-57.9%). In the group of patients with ALK-positive IFMT, crizotinib activity met the pre-specified response rate criteria set by the protocol.
« Limitations of the trial include that it is a noncomparative, single-arm study with a relatively small number of patients. Given the disease prevalence, a more definitive, randomised, comparative trial would not be possible, » says Schöffski.
« However, our study highlights how identifying the genetic drivers of a rare type of cancer can be used to find a new precision medicine for patients who otherwise have few treatment options," he adds. "The inclusion in our trial of a group of patients with ALK-negative inflammatory myofibroblastic tumors provides valuable insight into the selectivity of crizotinib and our understanding of this rare disease, even if we cannot formally compare the outcomes for the ALK-positive and -negative groups."
The trial results are published in The Lancet Respiratory Medicine.

These additional data align with previously released Brilacidin-OM results showing a risk reduction in the incidence of SOM, including up to an 80.3% risk reduction in the incidence of SOM among patients receiving more aggressive chemotherapy. Other previously released results indicate Brilacidin-OM also delayed onset of SOM. The Company is developing Brilacidin-OM under FDA Fast Track designation as a convenient, and clearly differentiated, therapy aimed to decrease incidence of SOM.
Initial Instance Duration of SOM was defined as the number of days from initial WHO Grade ≥3 during radiation therapy to the first WHO Grade 2 or lower OM Grade. Overall Duration of SOM was defined as the number of days from initial WHO Grade ≥3 during radiation therapy to the day prior to the next OM assessment after the last WHO Grade ≥3 during/after radiation therapy. Note: 50th percentiles are from Kaplan-Meier analysis. Patients who did not experience SOM have duration set to 0.

Previously, the Company reported statistically significant results showing Brilacidin-OM reduced the incidence of SOM in HNC patients receiving cisplatin administered in a high-dose regimen (80-100 mg/m2), approximately every 21 days. For the Modified Intent-to-Treat (mITT) population, Brilacidin-OM in the high-dose chemotherapy regimen reduced the incidence of SOM by 65.0% ([incidence control- incidence active]/incidence control) as compared with placebo (Brilacidin: 25.0%; placebo: 71.4%; p=0.0480). For the Per Protocol (PP) population, Brilacidin-OM in the high-dose chemotherapy regimen similarly reduced the incidence of SOM by 80.3% as compared with placebo (Brilacidin: 14.3%; placebo: 72.7%; p=0.0249).

Exploratory Endpoint: Unplanned Office Visits, Emergency Department Visits, and/or Hospital Admissions Due to OM

Positive OM assessment endpoints are additionally supported by zero (0) of the patients in the Brilacidin-OM group having unplanned office visits, ED visits, or hospital admissions due to OM, compared to four (4) patients in the placebo group.

Other Study Observations

Regardless of the oral sites irradiated (at least two sites from: buccal mucosa, floor of mouth, ventral/lateral tongue, and soft palate), the incidence by patient of Severe OM on Brilacidin-OM relative to placebo was consistently reduced.

Across cumulative radiation dose intervals, patients in the Brilacidin-OM group consistently reported less often feeling the sensation "swollen" (approximately half of that reported for the placebo group). "Burning" sensation also was reported consistently less frequently in the Brilacidin treatment group.

Patients in the Brilacidin-OM group appeared to trend more favorably over the course of chemoradiation treatment according to Eastern Cooperative Oncology Group (ECOG) Performance Status—a common set of criteria used in oncology trials to assess debility.

Management Comments

"Drug makers, the world-over, have spent decades and enormous sums in both money and resources trying to develop an effective OM drug in a bid to address dire patient needs as well as capture a tremendous market opportunity," commented Leo Ehrlich, Chief Executive Officer at Innovation Pharmaceuticals. "Yet, there is currently no drug approved to treat, let alone prevent, severe OM in patients with Head and Neck Cancer. Most Pharmas currently conducting OM trials target shortening the duration of severe OM as their primary endpoint, not reduction of incidence, like we did. The Brilacidin-OM Phase 2 trial met its primary objective and its key secondary objectives. As we continue to analyze subset data, we are extremely enthusiastic about observed trends. Hundreds of thousands of patients would benefit from a preventative OM treatment and we’re excited that Brilacidin-OM may one day provide these patients a much-needed breakthrough treatment option."

On April 16, 2018 Oregon Health & Science University (OHSU) Knight Cancer Institute and Aptose Biosciences Inc. (NASDAQ:APTO) (TSX:APS) reported the presentation of preclinical data demonstrating that CG’806, a highly potent pan-FLT3/pan-BTK inhibitor, kills malignant cells in samples from patients with various hematologic malignancies and demonstrates superiority to other kinase inhibitors (Press release, Aptose Biosciences, APR 16, 2018, View Source c=116148&p=RssLanding&cat=news&id=2342649 [SID1234525328]). The data were presented in a poster on Sunday, April 15, at the 2018 American Association for Cancer Research (AACR) (Free AACR Whitepaper) Conference being held April 14-18, in Chicago, IL.

The poster, entitled CG’806, a first-in-class pan-FLT3/pan-BTK inhibitor, demonstrates superiority to other FLT3 and BTK inhibitors against primary patient samples, demonstrated the broad activity of CG’806 against primary bone marrow specimens from patients with various hematologic malignancies. CG’806 is a small molecule that potently inhibits wild type (WT) FLT3, as well as FLT3 housing the ITD mutation or with point mutations in the tyrosine kinase domain (TKD, including D835G, D835Y, D835H) or in the gatekeeper region (F691L); it also inhibits BTK WT and BTK-C481S. As part of the Beat AML Initiative, researchers at OHSU tested CG’806 against freshly isolated primary samples from patients with acute myeloid leukemia (AML), chronic lymphocytic leukemia (CLL) and other hematologic malignancies to determine its potency and range of action. Against AML patient samples, CG’806 was evaluated relative to other FLT3 inhibitors. In parallel, CG’806 and ibrutinib, a covalent BTK inhibitor approved for CLL and certain other B-cell malignancies, were compared directly for sensitivities on primary CLL samples and various B-cell and other hematologic malignancies. CG’806 was shown to have greater potency against a broader subset of AML samples relative to other FLT3 inhibitors, including midostaurin, gilteritinib, quizartinib, sorafenib, crenolanib, and dovitinib. This was especially true in FLT3-ITD and FLT3-TKD positive cases, although enhanced activity was also observed in FLT3 WT samples. CG’806 was also shown to have greater potency and range of activity on primary CLL samples than ibrutinib.

"The clinical benefit of current FLT3 inhibitors in AML is transient, as resistance develops after several months of treatment," said Stephen E. Kurtz, Ph.D., lead author and Research Assistant Professor at the OHSU Knight Cancer Institute. "Similarly, ibrutinib, a covalent BTK inhibitor approved for CLL and certain other B-cell malignancies, is limited by acquired resistance, as well as refractory disease and tolerance challenges. As a pan-FLT3/pan-BTK inhibitor – especially in the absence of observed toxicity in murine AML models – CG’806 offers important potential to address these limitations."

"CG’806 appears superior to other FLT3 and BTK inhibitors, and the wealth of data supporting its development in AML and B-cell malignancies continues to grow," said William G. Rice, Ph.D., Chairman and Chief Executive Officer of Aptose. "These studies are critical for understanding how to develop and position CG’806 as we prepare for clinical development in these challenging hematologic malignancies."
Separately, Aptose researchers also announced new data on CG’806 presented at AACR (Free AACR Whitepaper) (see press release here). Both poster presentations will be published in the AACR (Free AACR Whitepaper) Conference Proceedings. The posters can also be accessed here or at the Publications & Presentations section of the Aptose website, www.aptose.com.

About CG’806

CG‘806 is an oral, first-in-class pan-FLT3/pan-BTK multi-kinase inhibitor. This small molecule demonstrates potent inhibition of wild type and mutant forms of FLT3 (including internal tandem duplication, or ITD, and mutations of the receptor tyrosine kinase domain and gatekeeper region), eliminates acute myeloid leukemia (AML) tumors in the absence of toxicity in murine xenograft models, and represents a potential best-in-class therapeutic for patients with AML. Likewise, CG’806 demonstrates potent, non-covalent inhibition of the wild type and Cys481Ser mutant forms of the BTK enzyme, as well as other oncogenic kinase pathways operative in B cell malignancies, suggesting CG’806 may be developed for various B cell malignancy patients (including CLL, MCL, DLBCL and others) that are resistant/refractory/intolerant to covalent BTK inhibitors. CG’806 is currently in preclinical development in partnership with CrystalGenomics

"In recent months, we have made meaningful progress advancing our business objectives, maturing SELLAS Life Sciences Group Ltd. into a publicly-traded company following the business combination and progressing our pipeline of cancer immunotherapies for patients with limited treatment options," said Angelos Stergiou, MD, ScD h.c., President & Chief Executive Officer of SELLAS. "We are particularly excited about our recent financing and the positive interim results from the Phase 2b NeuVax + Herceptin study announced earlier this month which we believe help position SELLAS for continued success throughout the remainder of 2018. We also look forward to commencing the Phase 1/2 clinical trial of galinpepimut-S in combination with Keytruda under our collaboration and supply agreement with Merck and our planned Phase 3 Acute Myeloid Leukemia program."
Recent Corporate and Pipeline Highlights

In April 2018, SELLAS announced positive interim data from the prospective, randomized, single-blinded, controlled Phase 2b independent investigator-sponsored clinical trial (IST) of trastuzumab (Herceptin) +/-nelipepimut-S (NeuVax) in HER 1+/2+ breast cancer patients in the adjuvant setting to prevent recurrences.

In March 2018, open label Phase 2 clinical and immunological data for SELLAS’ lead product candidate, galinpepimut-S (GPS) in patients with multiple myeloma (MM) was presented at the 2018 European Society for Blood and Marrow Transplantation (EBMT) 44th Annual Meeting in Lisbon, Portugal. Median progression-free survival (PFS) of 23.6 months was reported in the high-risk disease setting, compared to historically inferior outcomes while on an immunomodulatory drug (IMID) or proteasome inhibitor post-autologous stem cell transplant maintenance.

In March 2018, SELLAS appointed Barbara Wood as Executive Vice President, General Counsel and Corporate Secretary.

In March 2018, SELLAS entered into a definitive securities purchase agreement to issue up to 10,700 shares of its Series A convertible preferred stock and warrants to purchase 1,363,631 shares of its common stock in a private placement transaction to a select group of institutional investors, in Europe and the United States, for aggregate gross proceeds of $10.7 million. The closing of the first tranche for approximately $6.0 million took place on March 9, 2018. The closing of the second tranche for approximately $4.7 million is expected to occur by the end of April 2018 following stockholder approval.

In December 2017, SELLAS Life Sciences Group Ltd. ("SELLAS Ltd."), a privately-held Bermuda exempted company, completed a business combination (the "Merger") with Galena Biopharma, Inc. ("Galena"). Upon completion of the Merger, Galena was renamed "SELLAS Life Sciences Group, Inc.," began trading under a new ticker symbol "SLS" and the combined company now includes the late-stage pipelines of novel cancer immunotherapies for both hematologic and solid malignancies of SELLAS Ltd. and Galena.

In October 2017, SELLAS Ltd. entered into a clinical trial collaboration and supply agreement with Merck & Co. for a combination clinical trial targeting multiple cancer types, in which GPS will be administered in combination with Merck’s anti-PD-1 therapy KEYTRUDA (pembrolizumab) in a Phase 1/2 trial in five cancer indications, including both hematologic malignancies and solid tumors.

Year End 2017 Financial Results
For accounting purposes, SELLAS Ltd. is considered to have acquired Galena in the Merger; therefore, the financial statements of Galena became those of SELLAS Ltd. and the results reported are those of SELLAS Ltd.
Cash Position: As of December 31, 2017, cash and cash equivalents were $2.3 million, compared to $6.0 million as of December 31, 2016. Net cash used in operating activities was $11.0 million for the year ended December 31, 2017, compared to $11.9 million for the year ended December 31, 2016.
R&D Expenses: Research and development expenses were $6.1 million for the year ended December 31, 2017, as compared to $11.4 million for the year ended December 31, 2016. The $5.3 million decrease was primarily attributable to a decrease of $2.5 million in fees due under licensing and collaboration agreements, a decrease of $1.7 million in clinical trial expense, a $1.3 million decrease in manufacturing expenses, a $1.2 million decrease in consulting fees, and $0.2 million decrease in regulatory expenses. These decreases were partially offset by a $0.7 million increase in stock-based compensation and a $0.9 million increase in personnel related expenses. Overall, research and development expenses were reduced in 2017 as SELLAS Ltd. explored various strategic options.
G&A Expenses: General and administrative expenses were $15.1 million for the year ended December 31, 2017, as compared to $4.6 million for the year ended December 31, 2016. The $10.5 million increase was primarily due to $5.7 million of transaction costs related to the Merger and a $2.1 million increase in stock-based compensation from the acceleration of restricted stock units, and a $1.5 million increase in personnel related expenses due to an increase in headcount, $0.6 million increase in accounting and audit fees, and $0.6 million in outside consulting services. The $5.7 million of transactions costs consist of $2.9 million of banking fees, $1.6 million in legal fees, $1.0 million incentive fee payable through approximately $0.1 million in cash and the issuance of 119,672 shares of our common stock upon consummation, and $0.2 million in accounting and audit fees. The transaction costs incurred related to the Merger are non-recurring expenses for the year 2017.
Non-recurring Severance Costs: Severance costs incurred during the year ended December 31, 2017 include employee-related costs for severance of former Galena employees of $1.9 million.
Net Loss: Net loss was $23.8 million and loss attributable to common stockholders was $24.4 million for the year ended December 31, 2017, or a basic and diluted loss per share to common stockholders of $10.44, as compared to a net loss and loss attributable to common stockholders of $17.7 million for the year ended December 31, 2016, or a basic and diluted loss per share to common stock holders of $18.66.
