Enacted as part of the 2012 FDA Safety and Innovation Act (FDASIA), Breakthrough Therapy designation is intended to expedite the development and review of a potential new medicine if it is intended to treat a serious or life-threatening disease and preliminary clinical evidence indicates that the drug may demonstrate substantial improvement over existing therapies.1 The Breakthrough Therapy designation is distinct from the FDA’s other mechanisms to expedite drug development and review.2 ALK gene rearrangement is a genetic alteration that drives the development of lung cancer in some patients. 3,4 Due to additional mutations that the tumor may acquire during treatment, disease progression remains a challenge in patients with ALK-positive metastatic NSCLC.5

"This regulatory designation recognizes the potential for lorlatinib to provide an important treatment option for patients with ALK-positive NSCLC whose cancers have progressed despite treatment. Pfizer’s rapid development of lorlatinib reflects a commitment to developing biomarker-driven therapies to meet the evolving needs of patients," said Mace Rothenberg, MD, chief development officer, Oncology, Pfizer Global Product Development. "We look forward to working with the FDA to accelerate the development of this therapy."

The Breakthrough Therapy designation is supported by the efficacy and safety data of an ongoing Phase 1/2 clinical trial of lorlatinib, which includes patients with ALK-positive NSCLC who were previously treated with one or more ALK inhibitors.

Additionally, the Phase 3 CROWN study (NCT03052608) recently began enrolling patients. CROWN is an ongoing, open label, randomized, two-arm study comparing lorlatinib to crizotinib in the first-line treatment of patients with metastatic ALK-positive NSCLC. Please visit clinicaltrials.gov for more information on this study.

About Non-Small Cell Lung Cancer

Worldwide, lung cancer is the leading cause of cancer death in both men and women.6 NSCLC accounts for about 85 percent of lung cancer cases and remains difficult to treat, particularly in the metastatic setting.7 Approximately 57 percent of NSCLC patients are diagnosed late with metastatic, or advanced, disease where the five-year survival rate is only 5 percent. 8 NSCLC can be further categorized into distinct subsets that are classified by a number of factors, including histology and the molecular makeup of the tumor. Epidemiology studies suggest that approximately 3 to 5 percent of NSCLC tumors are ALK-positive.9

About Lorlatinib

Lorlatinib is an investigational next-generation ALK/ROS1 tyrosine kinase inhibitor that has been shown to be highly active in preclinical lung cancer models harboring chromosomal rearrangements of both ALK and ROS1. Lorlatinib was specifically designed to inhibit tumor mutations that drive resistance to other ALK inhibitors and to penetrate the blood brain barrier. Lorlatinib is an investigational agent and has not received regulatory approval for any indication anywhere in the world.

Abstract Title:
Clinical Trials of VAL-083 in Patients With Chemo-Resistant
Glioblastoma.
Abstract ID:
TPS2082
About VAL-083

VAL-083 is a "first-in-class," small-molecule DNA-targeting agent that demonstrated clinical activity against a range of cancers including GBM in historical clinical trials sponsored by the U.S. National Cancer Institutes (NCI). DelMar has demonstrated that VAL-083’s anti-tumor activity against GBM is unaffected by the expression of MGMT in vitro. High expression of MGMT in MGMT-unmethylated GBM patients is correlated with chemo-resistance and poor survival following treatment with temozolomide, the current standard-of-care. Further details can be found at View Source

VAL-083 has received an orphan drug designation in Europe for the treatment of malignant gliomas and the U.S. FDA Office of Orphan Products has granted an orphan designation to VAL-083 for the treatment of glioma, medulloblastoma and ovarian cancer. Based on historic clinical trials run by NCI, the modern phase I/II dose finding trial run by DelMar in GBM (ASCO 2016), and recent guidance from the FDA, the Company is embarking on multiple phase 2 and 3 clinical trials for VAL-083 encompassing both front-line and recurrent GBM therapy.

DelMar has announced plans to advance VAL-083 into a pivotal randomized multi-center Phase 3 clinical trial for the treatment of bevacizumab-failed GBM. DelMar has also initiated a Phase 2 trial for bevacizumab-naïve recurrent MGMT-unmethylated GBM patients in collaboration with the MD Anderson Cancer Center. A separate international Phase 2 trial for newly diagnosed MGMT-unmethylated GBM will be initiated at Sun-Yat Sen University in Guangzhou China. DelMar believes that data from its clinical trials, if successful, will form the basis of a new treatment paradigm for the vast majority of GBM patients whose tumors exhibit features that make them unlikely to respond to currently available therapies. The poster at ASCO (Free ASCO Whitepaper) 2017 will highlight the clinical results to date and the Company’s clinical trial designs for VAL-083 in GBM.

About Glioblastoma Multiforme (GBM)

GBM is the most common and aggressive primary brain cancer. Current standard of care includes surgery, radiation and treatment with temozolomide (TMZ), however nearly all tumors recur and the prognosis for recurrent GBM is dismal. Most GBM tumors have unmethylated promoter status for O6-methylguanine-DNA-methyltransferase (MGMT); a validated biomarker for TMZ-resistance. Second-line treatment with anti-angiogenic agent bevacizumab has not improved overall survival (OS) and 5-year survival is less than 3%. Dianhydrogalactitol (VAL-083) is a bi-functional alkylating agent targeting N7-Guanine and inducing interstrand DNA cross-links, double-strand breaks and cell death in GBM cell lines and GBM cancer stem cells, independent of MGMT status in vitro. VAL-083 readily crosses the blood-brain barrier and accumulates in brain tumor tissue. Our recent phase I/II clinical trial in recurrent GBM patients failing both TMZ and bevacizumab suggested that VAL-083 offers clinically meaningful survival benefits for patients with recurrent GBM and pinpointed a new dosing regimen (40 mg/m2/d on days 1, 2, and 3 of a 21-day cycle) which was well-tolerated and was selected for study in subsequent GBM trials. DelMar has initiated, or plans to initiate, three additional GBM trials, the results of which may support a new treatment paradigm in chemotherapeutic regimens for the treatment of GBM. These trials include:

i)
An ongoing single-arm, biomarker driven, Phase 2 study to determine if VAL-083 treatment of MGMT-unmethylated adult GBM patients at first recurrence/progression, prior to bevacizumab improves overall survival at 9 months, compared to historical control with lomustine (clinicaltrials.gov identifier: NCT02717962).
ii)
A planned pivotal Phase 3 study in recurrent GBM after failing both TMZ and bevacizumab. The control arm will consist of a limited number of salvage chemotherapies currently used in bevacizumab-failed GBM. If successful, this study will serve as the basis for a New Drug Application (NDA) submission for VAL-083.
iii)
A planned single arm, biomarker driven, Phase 2 study to confirm the tolerability and efficacy of VAL-083 in combination with radiotherapy in newly diagnosed MGMT-unmethylated GBM patients whose tumors are known to express high MGMT levels. (clinicaltrials.gov identifier: NCT03050736).

On April 27, 2017 Myriad Genetics, Inc. (NASDAQ: MYGN) and Clovis Oncology, Inc.

Under the agreement, Myriad will submit a supplementary premarket approval (sPMA) application under its existing PMA for BRACAnalysis CDx to include Rubraca. The Myriad sPMA submission will fulfill a post-approval regulatory commitment by Clovis Oncology to the Food and Drug Administration (FDA) for Rubraca. In December 2016, Rubraca was approved for women with advanced ovarian cancer who have been treated with two or more chemotherapies and whose tumors have a deleterious BRCA mutation as identified by an FDA-approved companion diagnostic test. The companion diagnostic test approved with Rubraca does not discriminate between germline and somatic mutations. Knowledge of germline status is important to provide patients appropriate counseling.

"BRACAnalysis CDx is the only germline companion diagnostic test approved by the FDA to identify patients with BRCA1/2 mutations, and we are excited to support Clovis’ clinical development program and help identify patients who are most likely to benefit from rucaparib," said Mark C. Capone, president and CEO, Myriad Genetics. "This agreement further solidifies Myriad’s leadership role in developing best-in-class companion diagnostics for use with PARP inhibitors and supports our goal of being the worldwide leader in personalized medicine.""This partnership with Myriad Genetics not only enables us to fulfill our post-marketing commitment to the FDA, but will enhance the companion diagnostic information already available to physicians and patients, providing a robust toolkit for personalizing treatment of patients with BRCA1/2 mutations," said Patrick J. Mahaffy, president and CEO, Clovis Oncology.

About Rubraca (rucaparib)
Rubraca is a PARP inhibitor indicated as monotherapy for the treatment of patients with deleterious BRCA mutation (germline and/or somatic) associated advanced ovarian cancer, who have been treated with two or more chemotherapies, and selected for therapy based on an FDA-approved companion diagnostic for Rubraca. The indication for Rubraca is approved under the FDA’s accelerated approval program based on objective response rate and duration of response, and is based on results from two multicenter, single-arm, open-label clinical trials. Continued approval for this indication may be contingent upon verification and description of clinical benefit in confirmatory trials. Please visit rubraca.com for more information.


About BRACAnalysis CDx
BRACAnalysis CDx is an in vitro diagnostic device intended for the qualitative detection and classification of variants in the protein coding regions and intron/exon boundaries of the BRCA1 and BRCA2 genes using genomic DNA obtained from whole blood specimens collected in EDTA. Single nucleotide variants and small insertions and deletions (indels) are identified by polymerase chain reaction (PCR) and Sanger sequencing. Large deletions and duplications in BRCA1 and BRCA2 are detected using multiplex PCR. BRACAnalysis CDx was reviewed and approved by the FDA in December 2014 for use as a companion diagnostic to aid in identifying ovarian cancer patients eligible for treatment with AstraZeneca’s PARP inhibitor, olaparib. This assay is for professional use only and is to be performed only at Myriad Genetic Laboratories, a single laboratory site located at 320 Wakara Way, Salt Lake City, UT 84108.

"Our pivotal luspatercept studies continue to gain momentum as enrollment nears completion, and new clinical data support the drug’s expanded development in patient groups in need of more treatment options," commented Habib Dable, President and Chief Executive Officer of Acceleron. "We now look forward to reporting topline results from the MEDALIST and BELIEVE Phase 3 studies in mid-2018 as we work together with Celgene to evaluate the full clinical potential of luspatercept."

Updated Phase 3 Clinical Trials Enrollment Guidance

Acceleron and Celgene provided updated guidance on the anticipated completion of patient enrollment for the MEDALIST and BELIEVE Phase 3 studies of luspatercept in MDS and beta-thalassemia, respectively. Based on accelerating rates of patient recruitment, the companies expect to achieve full enrollment of both studies in the second quarter of 2017, versus previous guidance of the second half of 2017.

New Phase 3 Clinical Trial

Acceleron and Celgene also plan to initiate a third Phase 3 trial of luspatercept. The new Phase 3 trial, expected to be initiated in early 2018, will evaluate luspatercept treatment versus standard-of-care in the first-line treatment setting for MDS patients. Current first-line, standard-of-care treatment for lower-risk MDS patients includes erythropoiesis-stimulating agents (ESAs) and/or regular red blood cell transfusions. The ongoing MEDALIST Phase 3 trial is evaluating luspatercept in ESA-refractory or -ineligible MDS patients.

Luspatercept Data at the Upcoming MDS Symposium

Acceleron and Celgene plan to report updated Phase 2 data on luspatercept in first-line, lower-risk MDS patients in an oral presentation at the 14th International Symposium on MDS on Saturday, May 6, 2017, in Valencia, Spain.

About Luspatercept

Luspatercept is a modified activin receptor type IIB fusion protein that acts as a ligand trap for members in the Transforming Growth Factor-Beta (TGF-beta) superfamily involved in the late stages of erythropoiesis (red blood cell production). Luspatercept regulates late-stage erythrocyte (red blood cell) precursor cell differentiation and maturation. This mechanism of action is distinct from that of erythropoietin (EPO), which stimulates the proliferation of early-stage erythrocyte precursor cells. Acceleron and Celgene are jointly developing luspatercept as part of a global collaboration. Acceleron and Celgene are enrolling Phase 3 clinical trials that are designed to evaluate the safety and efficacy of luspatercept in patients with myelodysplastic syndromes (the "MEDALIST" study) and in patients with beta-thalassemia (the "BELIEVE" study). For more information, please visit www.clinicaltrials.gov.

Luspatercept is an investigational product that is not approved for use in any country.
