Title: Inherited Germline Mutations in Men with Prostate Cancer.
Presenter: Robert Reid, M.D., Virginia Cancer Specialists.
Date: Sunday, February 9, 2018, 12:15 — 1:45 p.m. and 6:00 p.m. — 7:00 p.m.
Location: Poster Board E4; Poster Abstract 357.

The study will be presented by Robert Reid, M.D. from the Virginia Cancer Specialists who served as the lead investigator of this study. The study objective was to evaluate genetic testing using the 28-gene myRisk Hereditary Cancer test in 1,162 men with a personal history of prostate cancer. Of these, 64 percent had a history of prostate cancer, while 36 percent had a history of prostate cancer and at least one additional cancer. The results showed that 12.1 percent of men with prostate cancer were positive for one or more hereditary cancer mutations in the genes tested. Additionally, the positive rate was significantly higher among men with prostate cancer plus one other cancer (14.7 percent). The inherited mutations were found in genes with a well-known prostate cancer risk (i.e., BRCA2) as well as genes historically associated with other cancer types including breast and colon. These findings suggest that hereditary cancer testing in men with prostate cancer may aid in medical management decision making to reduce overall cancer risk.

"We believe hereditary cancer testing can help inform treatment decisions for these men, including whether to pursue active surveillance, increased screening for secondary cancers and potentially for treatment selection with PARP inhibitors or other medicines in the future," said Dr. Lancaster. "Additionally, once men know they carry an inherited mutation, they can encourage their family members to get tested to learn if they’re at increased risk for cancer and potentially help them prevent future cancers."

The National Comprehensive Cancer Network, American Urological Association (AUA) and an academic consensus panel all support hereditary cancer risk assessment for patients with prostate cancer deemed to be high risk due to metastatic disease or high grade cancer with a family history of BRCA associated cancers including breast, ovarian, pancreatic or prostate cancer.

Importantly, the AUA position states that: "Patients with localized prostate cancer who are at highest risk for developing metastatic castration-resistant prostate cancer, may have a higher incidence of germline DNA repair mutations than expected from published reports. The presence of germline DNA repair gene mutations has important implications for the prostate cancer patient in terms of general cancer screening and possible future prostate cancer treatment decisions. Additionally the presence of germline DNA repair mutations is of utmost relevance to the patient’s first-degree family members due to increased cancer risk and screening implications."

About Prostate Cancer
One in nine American men will have prostate cancer during his lifetime. Prostate cancer is the second leading cause of cancer death among American men and is the most commonly diagnosed. The American Cancer Society estimates in its Cancer Facts & Figures 2018 report that 164,690 men will be told they have prostate cancer in 2018. Currently, there are nearly 2.9 million American men living with the disease and every 18 minutes another American man dies from prostate cancer. That’s a little more than 80 deaths per day and 29,430 this year.

About Myriad myRisk Hereditary Cancer
The Myriad myRisk Hereditary Cancer test uses an extensive number of sophisticated technologies and proprietary algorithms to evaluate 28 clinically significant genes associated with eight hereditary cancer sites including: breast, colon, ovarian, endometrial, pancreatic, prostate and gastric cancers and melanoma. The myRisk Hereditary Cancer test offers physicians several distinct advantages over other commercial tests, including unsurpassed lab accuracy, industry leading variant classification and exceptional customer service.

CLR 131 is Cellectar’s investigational compound under development for a range of orphan designated cancers. CLR 131 utilizes the company’s patented PDC tumor targeting delivery platform to deliver the cytotoxic radioisotope iodine-131 directly to tumor cells. CLR 131 is currently being evaluated in a Phase 1 clinical trial in patients with relapse or refractory MM, as well as in a Phase 2 clinical trial for relapsed or refractory MM and select relapsed or refractory lymphomas. The U.S. Food and Drug Administration has granted orphan drug designation for CLR 131 in the treatment of MM.

"This patent allowance enhances our intellectual property estate and underscores the novelty of CLR 131 for the treatment of multiple myeloma, a life-threatening disease with high unmet medical need," said James Caruso, chief executive officer of Cellectar Biosciences. "Importantly, upon issuance, this patent will extend our coverage into the mid-2030s."

About Phospholipid Drug Conjugates

Cellectar’s product candidates are built upon a patented delivery and retention platform that utilizes optimized phospholipid ether-drug conjugates (PDCs) to target cancer cells. The PDC platform selectively delivers diverse oncologic payloads to cancerous cells and cancer stem cells, including hematologic cancers and solid tumors. This selective delivery allows the payloads’ therapeutic window to be modified, which may maintain or enhance drug potency while reducing the number and severity of adverse events. This platform takes advantage of a metabolic pathway utilized by all tumor cell types in all cell cycle stages. Compared with other targeted delivery platforms, the PDC platform’s mechanism of entry does not rely upon specific cell surface epitopes or antigens. In addition, PDCs can be conjugated to molecules in numerous ways, thereby increasing the types of molecules selectively delivered. Cellectar believes the PDC platform holds potential for the discovery and development of the next generation of cancer-targeting agents.

On February 7, 2018 Xcovery, a developer of targeted therapeutics for cancer, reported the initiation of its Phase 2 clinical trial of ensartinib (X-396), the company’s lead anaplastic lymphoma kinase (ALK) drug candidate, in patients with advanced malignant melanoma harboring alterations in ALK, including ALKATI (Press release, Xcovery, FEB 7, 2018, View Source [SID1234523776]). The trial is being conducted by the renowned Memorial Sloan Kettering Cancer Center (MSK) and led by MSK’s Dr. Alexander Shoushtari.

The primary objective of the study is to determine the clinical benefit rate (CBR) of ensartinib in this patient population. CBR is defined as any confirmed objective response by Response Evaluation in Solid Tumors (RECIST) 1.1 or stable disease until the 24-week assessment. This is an open label, single arm Phase 2 study, enrolling patients with melanoma either currently or previously having received a PD-1 based therapy and, if BRAF V600 mutated, a BRAF-based therapy. The study is comprised of two portions: the screening phase and treatment phase. In the screening phase, archival tumor tissues from patients deemed to be current or future candidates for this trial will be tested for the ALKATI alteration using a Nanostring-based RNA assay at MSK. Patients whose tumors express ALKATI will be eligible for the treatment phase.

"While there has been significant clinical advancements in the treatment of advanced malignant melanoma, 30 to 40 percent of patients do not respond to immune-based therapy or will develop therapeutic resistance. This is a promising trial that uses an RNA-based assay to identify an epigenentically-regulated tumor growth mechanism and if deemed favorable for further study, this trial could represent a new treatment option for patients who currently have few options," said Alexander Shoushtari, M.D., Department of Medicine/Melanoma and Immunotherapeutics Services and principal investigator of the study at MSK.

"We are honored to collaborate with the distinguished scientists and investigators at MSK who were the first to discover this novel ALK alternation in melanoma patients," said Lieming Ding, M.D., Chairman of Xcovery. "We hope that ensartinib will be a viable treatment option for these patients."

"The submission of our first NDA for duvelisib is a major milestone for Verastem and is the culmination of substantial effort by our employees and the investigators who have dedicated themselves toward developing a potential treatment option for patients who are in need of additional therapies. We are immensely grateful to all of the patients that participated in the duvelisib clinical trial program over the last few years," said Robert Forrester, President and Chief Executive Officer of Verastem. "Oral duvelisib is the first PI3K inhibitor to show efficacy as a monotherapy in a randomized Phase 3 study in patients with relapsed or refractory CLL/SLL. Duvelisib monotherapy has also demonstrated significant clinical activity in patients with double-refractory FL. We believe duvelisib will offer a convenient oral treatment alternative. We look forward to working with the FDA during the review process and to a potential U.S. approval decision for duvelisib in early 2019."

The NDA is supported by clinical data from the randomized Phase 3 DUO study demonstrating significant efficacy, along with a consistent and manageable safety profile, of duvelisib monotherapy in patients with relapsed or refractory CLL/SLL. The DUO study met its primary endpoint with oral duvelisib monotherapy achieving a statistically significant improvement in progression-free survival (PFS) compared to ofatumumab in patients with relapsed or refractory CLL/ SLL (median PFS of 13.3 months versus 9.9 months, respectively; HR=0.52; p<0.0001), representing a 48% reduction in the risk of disease progression or death. The NDA is also supported by results from the Phase 2 DYNAMO study in patients with indolent non-Hodgkin’s lymphoma that are double-refractory to both rituximab and chemotherapy or radioimmunotherapy, which also achieved its primary endpoint with an objective response rate (ORR) of 46% (p<0.0001). In the subset of patients enrolled in DYNAMO with double-refractory FL (n=83), duvelisib demonstrated an ORR of 41%.

About Duvelisib

Duvelisib is a first-in-class investigational, dual inhibitor of phosphoinositide 3-kinase (PI3K)-delta and PI3K-gamma, two enzymes known to help support the growth and survival of malignant B-cells and T-cells. PI3K signaling may lead to the proliferation of malignant B- and T-cells and is thought to play a role in the formation and maintenance of the supportive tumor microenvironment.1,2,3 Duvelisib was evaluated in late- and mid-stage extension trials, including DUO, a randomized, Phase 3 monotherapy study in patients with relapsed or refractory chronic lymphocytic leukemia (CLL)/small lymphocytic lymphoma (SLL),4 and DYNAMO, a single-arm, Phase 2 monotherapy study in patients with refractory indolent non-Hodgkin lymphoma (iNHL).5 Both DUO and DYNAMO achieved their primary endpoints and Verastem has submitted a New Drug Application (NDA) requesting the full approval of duvelisib for the treatment of patients with relapsed or refractory CLL/SLL, and accelerated approval for the treatment of patients with relapsed or refractory follicular lymphoma (FL). Duvelisib is also being developed by Verastem for the treatment of peripheral T-cell lymphoma (PTCL), and is being investigated in combination with other agents through investigator-sponsored studies.6 Information about duvelisib clinical trials can be found on www.clinicaltrials.gov.
