On September 9, 2015 Mirati Therapeutics, Inc. ("Mirati") (NASDAQ: MRTX), an oncology company focusing on genetic and epigenetic drivers of cancer, reported it will present data at the International Association of Lung Cancer (IASLC) 16th World Conference on Lung Cancer on the first non-small cell lung cancer (NSCLC) patient with AXL gene amplification enrolled in the MGCD265 Phase 1b expansion cohort (Filing, 8-K, Mirati, SEP 9, 2015, View Source [SID:1234507446]). Data will be presented showing the patient had a confirmed Partial Response (PR) based on RECIST criteria. Additionally, the Company announced a confirmed PR in a NSCLC patient with MET gene amplification who was enrolled in the MGCD265 expansion cohort.

"Out of four non-small cell lung cancer patients whom have had at least one scan in the ongoing MGCD265 expansion cohort, two patients have RECIST-confirmed PRs. Those PRs, together with tumor regressions seen in all four of these patients, demonstrate the potentially significant clinical benefit of MGCD265 in patients with lung cancer," said Charles M. Baum, M.D., Ph.D., President and CEO, Mirati. "The study is progressing well due to the enthusiasm of the clinical investigators, and this has resulted in increased screening and enrollment at the clinical trial sites. Currently, nine patients with MET or AXL genetic alterations have been enrolled in the study. In light of the dramatic response being presented in the patient with AXL gene amplification at today’s World Conference on Lung Cancer, we felt it was appropriate to provide an interim update on the program. As previously indicated, we will provide a more in-depth update when we have additional data."

NSCLC Patient with Axl Gene Amplification

The male patient was diagnosed with metastatic adenocarcinoma of the lung, with multiple tumors in both lungs which had spread to the lung cavity and lymph nodes. Prior to treatment with MGCD265, he had received multiple chemotherapies, as well as an experimental agent combined with chemotherapy, with the best response being disease progression. After 2 cycles of treatment with MGCD265, tumor imaging showed a PR with a tumor reduction of 42.3% compared to baseline. After 4 cycles of treatment, the PR was confirmed with a tumor reduction of 48.8% based on RECIST criteria. The patient, who remains on study in Cycle 7, also showed improvement in clinical symptoms. Prior to starting treatment with MGCD265, the patient was oxygen dependent. Shortly after treatment with MGCD265, he was off oxygen and able to ride his bike up to seven miles per day.

"To our knowledge, this is the first reported case of an objective response in a patient with a tumor harboring AXL gene amplification," said Geoffrey Shapiro, Principal Investigator and Director of the Early Drug Development Center, Department of Medical Oncology, Dana-Farber Cancer Institute. "This response, coupled with the patient’s significant symptomatic improvement, provides clinical validation that AXL genomic alterations can result in oncogene addiction in patients with non-small cell lung cancer. We will continue to explore MGCD265, a potent kinase inhibitor, in patients with MET or AXL genomic alterations, in an effort to improve cancer treatment by targeting genetic drivers of cancer."

Data from the study will be presented on September 9, 2015 in an oral presentation titled, "Evaluation of the MET/Axl Receptor Tyrosine Kinase (RTK) Inhibitor MGCD265 in a Patient with Metastatic Non-Small Cell Lung Cancer (NSCLC) Harboring AXL Amplification" by Lynette Sholl, M.D, Assistant Professor, Translational Research Group, Brigham and Women’s Hospital. The presentation is part of the New Kinase Targets session, Treatment of Advance Diseases – NSCLC track (abstract # 3611) from 6:30 – 8:00 PM MT/5:30 – 7:00 PM PT in Colorado Convention Center, Four Seasons Ballroom F3+F4.

Interim Update on the Ongoing MGCD265 Phase 1b Expansion Cohort

MGCD265 is an inhibitor of the MET and Axl receptor tyrosine kinases which, when mutated or amplified, can be drivers of tumor growth. Preclinical data have shown that MGCD265 can potently inhibit tumor cell growth in vitro, and demonstrate marked tumor regression in tumor xenograft models exhibiting MET gene amplification and MET exon 14 deletions.

This multi-national, multi-site, open label, single agent study is designed to evaluate the safety, pharmacokinetics/pharmacodynamics and clinical activity of twice-daily MGCD265 in patients who have failed at least one prior therapy. The study continues to enroll patients with MET or AXL gene alterations. MGCD265 has been well tolerated at the recommended Phase 2 dose, which has demonstrated full inhibition of both MET and Axl tyrosine kinases, and is the only kinase inhibitor that we know of in clinical development that has demonstrated potent and selective inhibition of both MET and Axl.

As of September 1, 2015, 9 patients with genetic alterations in MET or AXL have been enrolled in the expansion cohort, including 7 with NSCLC and 2 with other solid tumors. The Company disclosed that 2 of the 4 NSCLC patients, who are currently evaluable (having had at least 1 on-treatment scan), have confirmed PRs based upon RECIST criteria, including the patient with AXL amplification highlighted above and a patient with MET gene amplification. Both patients remain on study. All 4 of the evaluable NSCLC patients showed clinically significant tumor regressions. Of the 9 patients enrolled, 7 remain on study for up to 8+ months.

About MET and Axl in NSCLC

MET is highly expressed in NSCLC tumors. Extensive preclinical and emerging clinical data indicate that MET is a driver of tumor growth when it is genetically altered by point mutations, exon 14 deletion mutations, and/or gene amplification in a significant fraction (6-7%) of NSCLC patients. MET gene amplification and MET mutations, including exon 14 deletion mutations, each exhibit the key characteristics of driver oncogenes in NSCLC.

Axl is over-expressed in patients with advanced NSCLC and has been associated with poor prognosis. Amplification and rearrangements of the AXL tyrosine kinase gene also appear to be a driver of tumor growth and occur in up to 2% of patients with NSCLC. Preclinical data has shown that dysregulation of Axl is implicated in tumor progression and resistance to standard and targeted cancer therapies. Extensive preclinical and clinical data also indicate that both MET and Axl are important factors in resistance to EGFR inhibitors, as well as the third-generation EGFR inhibitors.

About MGCD265

MGCD265 is a tyrosine kinase inhibitor that potently and selectively targets tumors in patients with driver alterations in MET (gene amplification and mutations) and AXL (gene amplification and rearrangements) that occur in approximately 8% of patients with non-small cell lung cancer (NSCLC). MGCD265 is in the expansion phase of a Phase 1/1b dose escalation study for NSCLC patients with MET or AXL genetic alterations. Genetic alterations in these targets have been implicated as drivers of tumor growth and disease progression in NSCLC, gastroesophageal cancer and other solid tumors. Mirati retains worldwide rights to MGCD265.

On September 9, 2015 RedHill Biopharma Ltd. (Nasdaq:RDHL) (TASE:RDHL) ("RedHill" or the "Company"), an Israeli biopharmaceutical company primarily focused on late clinical-stage, proprietary, orally-administered, small molecule drugs for inflammatory and gastrointestinal (GI) diseases, including cancer, reported that the National Cancer Institute (NCI) has awarded a $2 million Small Business Innovation Research Program (SBIR) grant to support the planned Phase II study with YELIVA (ABC294640) for the treatment of refractory or relapsed multiple myeloma (Press release, RedHill Biopharma, SEP 9, 2015, View Source [SID:1234507433]).

The grant covers a three year period and was awarded to Apogee Biotechnology Corporation ("Apogee") in conjunction with Duke University. RedHill acquired the rights to YELIVA (ABC294640), a proprietary, first-in-class, orally-administered sphingosine kinase-2 (SK2) selective inhibitor, from Apogee in March 2015.

RedHill plans to initiate the Phase II study of YELIVA (ABC294640) for the treatment of refractory or relapsed multiple myeloma by the end of 2015. The open-label, dose escalation Phase II study will be conducted at Duke University Medical Center and is planned to enroll up to 77 patients with refractory or relapsed multiple myeloma who have previously been treated with proteasome inhibitors and immunomodulatory drugs. Dr. Yubin Kang, MD, Associate Professor in the Division of Hematologic Malignancies and Cellular Therapy in the Department of Medicine at Duke University Medical Center, will be the lead investigator for the study, which received Institutional Review Board (IRB) approval from Duke University (DUHS IRB).

The primary objectives of the first portion of the study (Phase Ib) are to assess safety and determine the maximum tolerated dose (MTD) in this group of patients. Secondary objectives include assessment of antitumor activity and determination of the pharmacokinetic (PK) and pharmacodynamic (PD) properties of YELIVA (ABC294640) in refractory or relapsed multiple myeloma patients.

The primary objectives of the second portion of the study (Phase II) are to assess the overall treatment response rate and overall survival. Secondary objectives include evaluating the treatment response of YELIVA (ABC294640) in patients with refractory or relapsed multiple myeloma after three cycles of treatment and evaluation of pharmacodynamic markers.

YELIVA (ABC294640) is a proprietary, first-in-class, orally-administered sphingosine kinase-2 (SK2) selective inhibitor, with anti-cancer and anti-inflammatory activities, targeting multiple oncology, inflammatory and GI indications. SK2 is an innovative molecular target for anti-cancer therapy because of its critical role in catalyzing the formation of the lipid-signaling molecule sphingosine 1-phosphate (S1P), which is known to regulate cell proliferation and activation of inflammatory pathways. By inhibiting SK2, YELIVA (ABC294640) could potentially be effective in treating multiple oncology, inflammatory, and gastrointestinal indications.

RedHill recently initiated a Phase I/II clinical study in the U.S. evaluating YELIVA (ABC294640) in patients with refractory/relapsed diffuse large B-cell lymphoma (DLBCL), primarily in patients with HIV-related DLBCL, also supported by a grant from the NCI Small Business Technology Transfer (STTR) program. A third Phase II clinical study is planned to evaluate YELIVA (ABC294640) as a radioprotectant to prevent mucositis in cancer patients undergoing therapeutic radiotherapy.

The ongoing and planned Phase II studies follow numerous successful pre-clinical studies conducted with YELIVA (ABC294640) in GI, inflammation, radioprotection and oncology models, as well as a Phase I study in patients with advanced solid tumors, supported by grants from the National Cancer Institute (NCI) and the FDA’s Office of Orphan Products Development (OOPD). RedHill recently announced that the last patient has completed the final scheduled follow-up visit in the Phase I study with YELIVA (ABC294640). Preliminary positive data from the Phase I study was presented by Apogee at the November 2013 Molecular Targets and Cancer Therapeutics meeting. The analysis of the study is currently ongoing and top-line results are expected to be announced early in the fourth quarter of 2015. A full analysis and the final Clinical Study Report (CSR) are expected by the end of the year or early 2016.

The studies with YELIVA (ABC294640) are registered on www.ClinicalTrials.gov, a web-based service by the U.S. National Institute of Health which provides public access to information on publicly and privately supported clinical studies.

About YELIVA (ABC294640):

YELIVA (ABC294640) is a first-in-class, proprietary sphingosine kinase-2 (SK2) selective inhibitor, administered orally, with anti-cancer and anti-inflammatory activities, targeting multiple potential oncology, inflammatory and gastrointestinal indications. By inhibiting the SK2 enzyme, YELIVA (ABC294640) blocks the synthesis of sphingosine 1-phosphate (S1P), a lipid that promotes cancer growth and pathological inflammation. YELIVA (ABC294640) was originally developed by U.S.-based Apogee Biotechnology Corp. and completed multiple successful pre-clinical studies in oncology, inflammation, GI, and radioprotection models, as well as the ABC-101 Phase I clinical study in cancer patients with advanced solid tumors. A Phase I/II clinical study evaluating YELIVA (ABC294640) in patients with refractory/relapsed diffuse large B-cell lymphoma (DLBCL) has been initiated in the U.S. The development of YELIVA (ABC294640) was funded to date primarily by grants and contracts from U.S. federal and state government agencies.

Financial Results

Since Cellectis did not have consolidated financial statements for individual quarters during fiscal year 2014, no comparative quarterly 2014 figures will be presented during 2015. Cellectis will publish quarter-over-quarter comparative figures starting with the first quarter of 2016.

Cellectis’s consolidated financial statements have been prepared in accordance with International Financial Reporting Standards, or IFRS, as issued by the International Accounting Standards Board ("GAAP").

Second Quarter 2015 Financial Results

Cash Position: As of June 30, 2015 Cellectis had €283.9 million in cash and cash equivalents compared to €112.3 million as of December 31, 2014. This increase is primarily attributable to the $228 million of proceeds from the U.S. initial public offering in March 2015.

Revenues and Other Income: Total revenues and other income were €8.0 million for the second quarter 2015 and primarily comprised €6.6 million of collaboration revenues and €0.9 million of license revenues.

Total Operating Expenses and Other Operating Income: Total operating expenses for the second quarter of 2015 were €20.1 million, which includes non-cash stock-based compensation expenses of €7.2 million.

R&D Expenses: Research and development expenses for the second quarter of 2015 were €10.6 million, including personnel expenses of €7.6 million and external purchases and other expenses of €3.0 million. Research and development expenses for the second quarter notably reflected the impacts of (i) non-cash stock-based compensation expense of €3.3 million and (ii) social charges related to free shares granted during the second quarter of €1.8 million.

SG&A Expenses: Selling, general and administrative expenses were €9.1 million for the second quarter of 2015, and included personnel expenses of €6.3 million and external purchases and other expenses of €2.8 million. SG&A expenses for the second quarter notably reflected the impacts of (i) non-cash stock-based compensation expense of €3.8 million and (ii) social charges related to free shares granted during the second quarter of €1.8 million.

Financial Loss: Financial loss was €10.0 million for the second quarter of 2015, which is primarily attributable to an unfavorable Euro-Dollar exchange rate applied to U.S. dollar-denominated cash and cash equivalents during the quarter.

Net Loss Attributable to Shareholders of Cellectis: Net loss attributable to shareholders of Cellectis was €22.2 million, or €0.63 per share, for the second quarter of 2015. The decrease of €28.3 million in net earnings, compared to the first quarter 2015 net gain attributable to shareholders of Cellectis of €6.1 million, notably reflects the effects of unfavorable Euro-Dollar exchange rates with respect to our U.S. Dollar cash and cash equivalent accounts and to a lesser extent the impact of non-cash stock-based compensations during the second quarter of 2015. Adjusted net loss attributable to shareholders of Cellectis for the second quarter of 2015, which excludes a non-cash stock-based compensation expense of €7.1 million, was €15.0 million, or €0.43 per share.

Alectinib was granted Breakthrough Therapy Designation by FDA in June 2013 for patients with ALK positive NSCLC who have progressed on crizotinib.

Alectinib is a highly selective, CNS-active ALK inhibitor created by Chugai. Alectinib matches with the Personalized Healthcare Strategy promoted by Chugai and Roche. It has been reported that 2 to 5 percent of patients with NSCLC express a chromosomal rearrangement which leads to fusion of the ALK gene with another gene1. ALK kinase signaling is constantly active in cells with such fusion genes, resulting in uncontrolled growth of tumor cells and transforming the cells into tumor cells2, 3. Alectinib exerts its anti-tumor effect by selectively inhibiting ALK kinase activity to inhibit tumor cell proliferation and induce cell death4. In addition, alectinib is not recognized by the transporter proteins in the blood brain barrier that actively pump molecules out of the brain.

Alectinib is active in the central nervous system and has proven activity against brain metastases.

In Japan, alectinib [brand name; Alecensa capsule 20mg and 40mg] was become available to patients with "ALK fusion gene positive unresectable, recurrent/advanced NSCLC" in September 2014 and is marketed by Chugai. The rights for Alecensa in overseas countries including Europe and the US were out-licensed to Roche, and clinical trials of Alecensa (Roche Development Code: RG7853) for patients with NSCLC who have ALK mutation are currently ongoing in the US, Europe and other countries.

Two pivotal clinical phase I/II trials formed the basis for the new drug application.

NP28673 study
NP28673 is a phase I/II global, single arm, open-label, multicentre trial evaluating the safety and efficacy of alectinib in 138 people with ALK positive NSCLC whose disease progressed on crizotinib.

The study showed by assessment of an independent review committee an ORR in 50.0% of people treated with alectinib, as measured by RECIST criteria.

An investigator assessment also showed tumours shrank in 47.8% of people who received alectinib.

CNS tumours shrank in response to alectinib in 57.1% of people whose disease had spread to the brain or other parts of the CNS.
In addition, the people whose tumours shrank in response to alectinib continued to respond for a median of 11.2 months (Duration of Response (DOR), immature data).

The median progression-free survival (PFS) for people who received alectinib was 8.9 months.

Alectinib demonstrated a safety profile consistent with that observed in previous studies.

The most common (occurring in at least 2% of people) Grade 3 or higher adverse event was shortness of breath (dyspnoea; 4%).
NP28761 study
NP28761 is a phase I/II North American, single arm, open-label, multicentre trial evaluating the safety and efficacy of alectinib in 87 people with ALK positive NSCLC whose disease progressed on crizotinib.

The study showed by assessment of an independent review committee an ORR in 47.8% of people treated with alectinib, as measured by RECIST criteria.

An investigator assessment showed tumours shrank in 46.0% of people who received alectinib.

CNS tumours shrank in response to alectinib in 68.8% of people whose disease had spread to the brain or other parts of the CNS.
In addition, the people whose tumours shrank in response to alectinib continued to respond for a median of 7.5 months (DOR, immature data).

The immature median PFS was 6.3 months.
Alectinib demonstrated a safety profile consistent with that observed in previous studies.
The most common (occurring in at least 2% of people) Grade 3 or higher adverse events were an increase in muscle enzymes (increased blood levels of creatine phosphokinase; 8%), increased liver enzymes (alanine aminotransferase; 6%, and aspartate aminotransferase; 5%) and shortness of breath (dysponea; 3%).

On September 8, 2015 DelMar Pharmaceuticals, Inc. (OTCQX: DMPI) ("DelMar" and the "Company"), a biopharmaceutical company focused on the development and commercialization of new cancer therapies, reported an overview of its planned clinical trial protocol for Company’s lead product candidate VAL-083 (dianhydrogalactitol) in the treatment of non-small cell lung cancer (NSCLC) (Press release, DelMar Pharmaceuticals, SEP 8, 2015, http://ir.delmarpharma.com/news/detail/779/delmar-pharmaceuticals-presents-clinical-protocol-for-advancement-of-val-083-into-phase-iv-studies-as-a-treatment-for-non-small-cell-lung-cancer [SID:1234507420]).

The Company presented the VAL-083 NSCLC clinical development plan in a poster entitled, "Post-Market Clinical Trial of Dianhydrogalactitol in the Treatment of Relapsed or Refractory Non-Small Cell Lung Cancer" at the 16th World Conference on Lung Cancer in Denver, Colorado.

VAL-083 is a "first-in-class" bi-functional alkylating agent meditating inter-strand DNA crosslinks at N7 of guanine that has been approved by the Chinese Food and Drug Administration (CFDA) for the treatment of lung cancer. However, use of VAL-083 in China has been limited by a lack of modern data, poor distribution, and preference for targeted therapies such as tyrosine kinase inhibitors (TKIs) in the modern era.

The study will enroll up to 20 adult patients with NSCLC in an open-label post market Phase IV clinical trial to investigate the activity of VAL-083 in NSCLC patients who have failed standard platinum doublet therapy. The primary goal is the assessment disease control rate, defined as objective response rate, complete (CR) and partial (PR) response rates, and stable disease (SD). Secondary endpoints will include evaluation of progression free survival (PFS) and overall survival (OS). Results will provide guidance to treating physicians under the context of VAL-083’s current approval in China and clinical proof-of-concept to support DelMar’s global development of VAL-083 as a potential new treatment for NSCLC.

The clinical trial will be initiated in Shanghai under the terms of DelMar’s collaboration with Guangxi Wuzhou Pharmaceutical (Group) Co., Ltd. Under the terms of the collaboration, Guangxi Wuzhou Pharmaceuticals is responsible for funding VAL-083 clinical research in China and DelMar is responsible for management of the clinical trials.

"Earlier this year, we presented preclinical data supporting the potential of VAL-083 as a valuable therapeutic option in the modern treatment of lung cancer, particularly in patients who have failed or are unlikely to respond to current standard of care. Our research also suggests that the combination of VAL-083 with either cisplatin or oxaliplatin provides a super-additive (synergistic) effect against NSCLC cell lines, including those resistant to TKI therapy in vitro," stated Jeffrey Bacha, president & CEO of DelMar Pharmaceuticals. "The upcoming Phase IV trial will further evaluate VAL-083’s potential to address a significant unmet need in platinum drug-resistant NSCLC. The clinical outcomes from this study will be important in developing additional CFDA treatment guidelines to expand VAL-083 beyond its currently approved indication in lung cancer in China."

"Importantly, we believe data from this post-market study in China will also establish global proof-of-concept to support a global clinical development program with VAL-083 in NSCLC," Mr. Bacha added.

The trial will follow the dosing regimen in accordance with the approved label in China. Patients will receive VAL-083 intravenous (IV) dose of 40 mg/day for five consecutive days, with one to two weeks rest, for two courses, followed by maintenance therapy 40 mg/day IV for five consecutive days every 28 days. Patients will continue to receive treatment until withdrawal criteria are met or the patient receives up to 12 cycles of therapy, whichever comes first. Patients will be monitored for objective responses, progression-free survival, survival, and quality-of-life. Following tumor assessments at screening, evaluation of tumor response conforming to RECIST v1.1 will be documented prior to every other new 28-day maintenance treatment cycle, commencing with maintenance Cycle #2.

PHASE IV CLINICAL STUDY OF DIANHYDROGALACTITOL (VAL-083) IN RELAPSED OR REFRACTORY NSCLC

Protocol Summary

This is an open label post-market Phase IV study of VAL-083 in treatment of NSCLC patients who have failed standard platinum doublet therapy. Up to 20 patients will be enrolled into the study. Study patients will receive VAL-083 intravenous (IV) dose of 40 mg/day for five consecutive days, with 1-2 weeks rest, for two courses, followed by maintenance therapy 40 mg/day IV for five consecutive days every 28 days. Patients will continue to receive treatment until withdrawal criteria are met or the patient receives up to 12 cycles of therapy, whichever comes first. Patients will be monitored for objective responses, progression-free survival, survival, and quality-of-life (using a quality-of-life instrument for patients with lung cancer). Following tumor assessments at screening, evaluation of tumor response conforming to RECIST v1.1 will be documented prior to every other new 28-day maintenance treatment cycle, commencing with maintenance Cycle #2.

Primary goals
To determine activity of VAL-083 in NSCLC patients who have failed standard platinum doublet therapy, as assessed by disease control rate, defined as objective response rate, complete (CR) and partial (PR) response rates, and stable disease (SD) in order to provide guidance to treating physicians under the context of VAL-083’s current approval in China.

Secondary goals
To determine the progression-free survival rate of NSCLC patients who have failed standard platinum doublet therapy when treated with VAL-083; to determine the overall survival of NSCLC patients who have failed standard platinum doublet therapy when treated with VAL-083; and to evaluate the quality of life and impact on disease symptoms following treatment with VAL-083.

Study duration
The study will be considered complete when the last patient either experiences disease progression or an intolerable toxicity, or withdraws from the study. The study is anticipated to take approximately 1-2 years.

About Lung Cancer
Lung cancer is a leading cause of cancer-related mortality around the world. In general, prognosis for lung cancer patients remain poor, with 5-year relative survival less than 14% among males and less than 18% among females in most countries. Globally, the market for lung cancer treatments may exceed $7 billion by 2019 according to report published by Transparency Market research. Non-small cell lung cancer is the most common type of lung cancer, accounting for 85% of all lung cancer cases in the United States and approximately 90% of lung cancer cases diagnosed in China. NSCLC is usually treated with surgery followed by treatment with either tyrosine kinase inhibitors (TKIs) or platinum-based chemotherapy regimens. TKI resistance has emerged as a significant unmet medical need, and long-term prognosis with platinum-based therapies is poor.

About VAL-083
VAL-083 is a "first-in-class", small-molecule chemotherapeutic. In more than 40 Phase I and II clinical studies sponsored by the U.S. National Cancer Institute, VAL-083 demonstrated safety and efficacy in treating a number of cancers including lung, brain, cervical, ovarian tumors and leukemia. VAL-083 is approved in China for the treatment of chronic myelogenous leukemia (CML) and lung cancer and has received orphan drug designation in Europe and the U.S. for the treatment of gliomas.

DelMar is currently studying VAL-083 in a multi-center Phase I/II clinical trial for patients with refractory GBM in accordance with the protocol that has been filed with the U.S. Food and Drug Administration (FDA) at five clinical centers in the United States: Mayo Clinic (Rochester, MN); UCSF (San Francisco, CA) and three centers associated with the Sarah Cannon Cancer Research Institute (Nashville, TN, Sarasota, FL and Denver, CO). As a potential treatment for glioblastoma, VAL-083’s mechanism of action appears to be unaffected by the expression of MGMT, a DNA repair enzyme that is implicated in chemotherapy resistance and poor outcomes following front-line treatment with Temodar (temozolomide).
