On November 16, 2018 Novartis reported the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) has adopted a positive opinion recommending an expanded indication for Kisqali (ribociclib), the CDK4/6 inhibitor with the largest body of first-line clinical trial evidence demonstrating consistent, superior and sustained efficacy compared to endocrine therapy alone (Press release, Novartis, NOV 16, 2018, View Source [SID1234531397]). CHMP recommended Kisqali for the treatment of women with hormone receptor positive, human epidermal growth factor receptor-2 negative (HR+/HER2-) locally advanced or metastatic breast cancer in combination with fulvestrant as initial endocrine-based therapy and in women who have received prior endocrine therapy. The positive opinion also recommended approval of Kisqali in combination with endocrine therapy and a luteinising hormone-release hormone agonist (LHRH) for pre- and perimenopausal women.

"Today’s CHMP opinion brings us one step closer to providing more women with HR+/HER2- advanced breast cancer in Europe with a treatment option," said Liz Barrett, CEO, Novartis Oncology. "The MONALEESA Phase III program enrolled more than 2,000 women, giving Kisqali by far the most extensive first-line evidence in clinical trials among any of the CDK4/6 inhibitors. This is another testament to how we are reimagining cancer."

This positive CHMP opinion is based on data from the Phase III MONALEESA-7 and MONALEESA-3 trials. These trials demonstrated prolonged progression-free survival (PFS) for Kisqali-based regimens compared to endocrine therapy alone and showed improvements as early as eight weeks after start of treatment with Kisqali combination therapy.

In MONALEESA-7, Kisqali plus an aromatase inhibitor and goserelin nearly doubled the median PFS compared to an aromatase inhibitor and goserelin alone in pre- or perimenopausal women (27.5 months compared to 13.8 months; HR=0.569; 95% CI: 0.436-0.743)[3]. In MONALEESA-3, Kisqali plus fulvestrant demonstrated a median PFS of 20.5 months compared to 12.8 months for fulvestrant alone (HR=0.593; 95% CI: 0.480-0.732) across the overall population of first-line and second-line postmenopausal women[4]. Across the two trials, the most common adverse reactions (incidence >=20%) were neutropenia, nausea, infections, fatigue, diarrhea, leukopenia, vomiting, alopecia, headache, constipation, rash and cough[3],[4].

Globally, an estimated 267,000 women will be diagnosed with advanced breast cancer each year and up to one-third of patients with early-stage breast cancer will subsequently develop advanced disease[5],[6]. One in five women diagnosed with breast cancer in Europe are younger than 50 years old[7]. Premenopausal breast cancer is a biologically distinct and more aggressive disease than postmenopausal breast cancer, and it is the leading cause of cancer death in women 20-59 years old[1],[8]. These young women face specific challenges, including induction of premature menopause, emotional distress and strain on their professional and personal lives[9],[10],[11].

The European Commission will review the CHMP recommendation and usually delivers its final decision within two months. The decision will be applicable to all 28 European Union member states plus Iceland, Norway and Liechtenstein. Additional regulatory filings are underway with other health authorities worldwide.

About Kisqali (ribociclib)
Kisqali is a selective cyclin-dependent kinase inhibitor, a class of drugs that help slow the progression of cancer by inhibiting two proteins called cyclin-dependent kinase 4 and 6 (CDK4/6). These proteins, when over-activated, can enable cancer cells to grow and divide too quickly. Targeting CDK4/6 with enhanced precision may play a role in ensuring that cancer cells do not continue to replicate uncontrollably[1].

Kisqali was initially approved by the US Food and Drug Administration (FDA) in March 2017 and by the European Commission in August 2017, as initial endocrine-based therapy for postmenopausal women with HR+/HER2- locally advanced or metastatic breast cancer in combination with an aromatase inhibitor based on findings from the pivotal MONALEESA-2 trial[12]. In July 2018, Kisqali was approved by the FDA for the treatment of pre-, peri- or postmenopausal women in the US, and indicated for use in combination with fulvestrant as both first- or second-line therapy in postmenopausal women[1].

Kisqali is approved for use in more than 70 countries around the world, including the United States and European Union member states. Kisqali is not currently approved for use in combination with fulvestrant or in premenopausal women in Europe. Kisqali was developed by the Novartis Institutes for BioMedical Research (NIBR) under a research collaboration with Astex Pharmaceuticals[12].

Important Safety Information FROM THE KISQALI EU SmPC
KISQALI (ribociclib) is a prescription medicine approved in combination with an aromatase inhibitor as initial endocrine – based therapy in women with hormone receptor (HR)-positive, human epidermal growth factor receptor 2 (HER2)-negative advanced or metastatic breast cancer or fulvestrant as initial endocrine – based therapy or following disease progression on endocrine therapy in postmenopausal women with hormone receptor (HR)-positive, human epidermal growth factor receptor 2 (HER2)-negative advanced or metastatic breast cancer. It is not known if KISQALI is safe and effective in children or adolescents. KISQALI can cause a heart problem known as QT prolongation. This condition can cause an abnormal heartbeat and may lead to death. KISQALI is not indicated for concomitant use with tamoxifen due to an increased risk of QT prolongation. Patients should tell their health care provider right away if they have a change in their heartbeat (a fast or irregular heartbeat), or if they feel dizzy or faint. KISQALI can cause serious liver problems. Patients should tell their health care provider right away if they get any of the following signs and symptoms of liver problems: yellowing of the skin or the whites of the eyes (jaundice), dark or brown (tea-colored) urine, feeling very tired, loss of appetite, pain on the upper right side of the stomach area (abdomen), and bleeding or bruising more easily than normal. Low white blood cell counts are very common when taking KISQALI and may result in infections that may be severe. Patients should tell their health care provider right away if they have signs and symptoms of low white blood cell counts or infections such as fever and chills. Before taking KISQALI, patients should tell their health care provider if they are pregnant, or plan to become pregnant as KISQALI can harm an unborn baby. Females who are able to become pregnant and who take KISQALI should use highly effective birth control during treatment and for at least 3 weeks after the last dose of KISQALI. Do not breastfeed during treatment with KISQALI and for at least 3 weeks after the last dose of KISQALI. Patients should tell their health care provider about all of the medicines they take, including prescription and over-the-counter medicines, vitamins, and herbal supplements since they may interact with KISQALI. Patients should avoid grapefruit or grapefruit juice while taking KISQALI. The most common side effects (incidence >=20%) include infections, white blood cell count decreases, headache, cough, nausea, tiredness, diarrhea, vomiting, constipation, hair loss and rash. The most common Grade 3/4 side effects (incidence >5%) were infections, low neutrophils, low leukocytes, low red blood cells, abnormal liver function tests, low lymphocytes, low phosphate levels and vomiting. Abnormalities were observed in hematology and clinical chemistry laboratory tests.

On November 16, 2018 The Janssen Pharmaceutical Companies of Johnson & Johnson reported that the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) reported it has issued a positive opinion for apalutamide, a next generation oral androgen receptor inhibitor for the treatment of adult patients with non-metastatic castration-resistant prostate cancer (nmCRPC) who are at high risk of developing metastatic disease.2 The CHMP’s positive opinion will now be reviewed by the European Commission (EC), which has the authority to grant approval for the use of apalutamide (Press release, Johnson & Johnson, NOV 16, 2018, View Source [SID1234531398]).

The CHMP’s positive opinion is based on data from the pivotal SPARTAN Phase 3 clinical study which assessed the safety and efficacy of apalutamide versus placebo in patients with nmCRPC who have a rapidly rising prostate specific antigen (PSA) level despite receiving continuous androgen deprivation therapy (ADT). The SPARTAN clinical study showed that apalutamide, when added to ADT, significantly reduced the risk of developing distant metastasis or death (metastasis free survival [MFS]) by 72 percent, compared to placebo in combination with ADT (HR = 0.28; 95% CI, 0.23-0.35; P < 0.001). The median MFS was improved by over two years (40.5 months vs 16.2 months) in patients with nmCRPC whose PSA is rapidly rising.1 This study was published in The New England Journal of Medicine.

The most common Grade 3/4 treatment-emergent adverse events in the SPARTAN study were hypertension (14.3 percent vs. 11.8 percent), rash (5.2 percent vs. 0.3 percent), fall (1.7 percent vs. 0.8 percent) and fracture (2.7 percent vs. 0.8 percent). Treatment discontinuation due to adverse events was 11 percent in the apalutamide arm compared to 7 percent in the placebo arm. Rates of serious adverse events were similar in the apalutamide in combination with ADT arm versus placebo in combination with ADT arm (25 percent vs. 23 percent respectively).1

"Data from the SPARTAN study showed that apalutamide significantly improves metastasis free survival for patients with castration-resistant prostate cancer," said Dr Simon Chowdhury, Consultant Medical Oncologist, Guy’s and St Thomas’ Hospitals. "Nearly 90 percent of patients with castration-resistant prostate cancer will eventually develop bone metastases. At that point their prognosis worsens dramatically. Delaying the spread of cancer is therefore critical for patients living with prostate cancer."*

"We are pleased with the CHMP’s decision to recommend approval of apalutamide for the treatment of patients with high-risk non-metastatic castration-resistant prostate cancer," said Dr. Ivo Winiger-Candolfi M.D., Janssen Oncology Solid Tumor Therapy Area Lead, Europe, Middle East and Africa, Cilag GmbH International. "We know that each prostate cancer patient journey is unique and today’s positive CHMP opinion brings us one step closer to offering patients an effective treatment option that delays the spread of their disease."

About Non-Metastatic Castration-Resistant Prostate Cancer

Non-metastatic castration-resistant prostate cancer (CRPC) refers to a disease stage when the cancer no longer responds to medical or surgical treatments that lower testosterone, but has not yet been discovered in other parts of the body using a bone scan or CT scan.3 Features include: lack of detectable metastatic disease; rapidly rising prostate-specific antigen while on androgen deprivation therapy (ADT) and serum testosterone level below 50 ng/dL.3 Ninety percent of patients with non-metastatic CRPC will eventually develop bone metastases, which can lead to pain, fractures and spinal cord compression.4 The relative 5-year survival rate for patients with distant stage castration sensitive or castration resistant prostate cancer is 30 percent.5,6

About apalutamide

Apalutamide is an investigational, next-generation oral androgen receptor (AR) inhibitor that blocks the androgen signaling pathway in prostate cancer cells. Apalutamide inhibits the growth of cancer cells in three ways: by preventing the binding of androgen to the AR; by stopping the AR from entering the cancer cells; and by preventing the AR from binding to the DNA of the cancer cell.7

Janssen submitted a Marketing Authorisation Application to the European Medicines Agency (EMA) in February 2018 seeking approval for apalutamide for the treatment of patients with high-risk non-metastatic castration-resistant prostate cancer (nmCRPC). Apalutamide received approval from the United States Food and Drug Administration for the treatment of patients with nmCRPC in February 2018, shortly followed by approvals in Canada, Australia, Argentina and Brazil.8,9,10,11

On November 16, 2018 Genzada Pharmaceuticals USA Inc., a subsidiary of Ionics Life Sciences Limited (Genzada), reported that the U.S. Food and Drug Administration (FDA) has approved its Investigational New Drug (IND) application for a Phase 1 human clinical trial of the company’s flagship molecule GZ17-6.02 (6.02) for patients with advanced solid organ tumors or lymphoma (Press release, Genzada Pharmaceuticals, NOV 16, 2018, View Source [SID1234531399]).

"We are excited to bring 6.02 to the oncology community and we look forward to demonstrating its safety and efficacy as we move through the clinical trials process," said Cameron E. West, MD, FAAD, chief operating officer of Genzada. "Based on numerous preclinical studies, we believe this therapeutic will be very well-tolerated and will achieve meaningful outcomes for cancer patients."

6.02 has shown preclinical success in several therapeutic contexts, notably for pancreatic cancer and head and neck squamous cell carcinoma.

"It is great news that the IND clearance has been granted for 6.02," said Daniel D. Von Hoff, MD, chief development officer at TD2 and adviser to Genzada. TD2 supported the research sponsor with its regulatory submissions, including the completion and filing of the drug’s IND application. The clinical research organization (CRO) will continue to manage the clinical trial for 6.02. "I know how hard the team has worked to get to this milestone for this very interesting combination with a unique mechanism of action."

Functionally, the compound acts as an inhibitor to super-enhancers, the areas of the genome bound by transcription factors that are uniquely susceptible to repair signal disruption. 6.02 can inhibit several super-enhancer targets based on the cancer of origin.

GZ17-6.02 is derived in part from Arum palaestinum (black calla lily), a native plant found in several regions of the Middle East. Similar to the vinca alkaloids and taxanes, 6.02 is now a fully synthesized therapeutic, originally derived from naturally occurring compounds.

Enrollment of the first patient for the 6.02 trial will take place through the HonorHealth Research Institute, and will be announced in the coming months as the study initiates.

On November 16, 2018 Seattle Genetics, Inc. (Nasdaq:SGEN) reported a new approval for ADCETRIS (brentuximab vedotin) in combination with CHP chemotherapy (cyclophosphamide, doxorubicin, prednisone) from the U.S. Food and Drug Administration (FDA) for adults with previously untreated systemic anaplastic large cell lymphoma (sALCL) or other CD30-expressing peripheral T-cell lymphomas (PTCL), including angioimmunoblastic T-cell lymphoma and PTCL not otherwise specified (Press release, Seattle Genetics, NOV 16, 2018, View Source [SID1234531400]). The approval is based on the successful outcome of the phase 3 ECHELON-2 clinical trial that compared ADCETRIS plus CHP to CHOP (cyclophosphamide, doxorubicin, vincristine, prednisone). The FDA granted Breakthrough Therapy designation and Priority Review to this supplemental Biologics License Application (BLA) and reviewed it under the Real-Time Oncology Review Pilot Program leading to approval less than two weeks after submission of the complete application.

"The current standard of care for initial treatment of peripheral T-cell lymphoma is multi-agent chemotherapy. That treatment has not significantly changed in decades and is too often unsuccessful in leading to long-term remissions, underscoring the need for new treatments," said Steven Horwitz, M.D., Department of Medicine, Lymphoma Service, Memorial Sloan Kettering Cancer Center, New York. "The ECHELON-2 clinical trial demonstrated ADCETRIS plus CHP was superior to the current standard of care, CHOP, for both progression-free survival and all other key secondary endpoints, including, most importantly, overall survival. With this approval, clinicians have the opportunity to transform the way newly diagnosed CD30-expressing PTCL patients are treated."

This is the sixth FDA-approved indication for ADCETRIS, which also has approval for adult patients with: (1) previously untreated Stage III or IV classical Hodgkin lymphoma (cHL), in combination with doxorubicin, vinblastine, and dacarbazine (AVD), (2) cHL at high risk of relapse or progression as post-autologous hematopoietic stem cell transplantation (auto-HSCT) consolidation, (3) cHL after failure of auto-HSCT or failure of at least two prior multi-agent chemotherapy regimens in patients who are not auto-HSCT candidates, (4) sALCL after failure of at least one prior multi-agent chemotherapy regimen, and (5) primary cutaneous anaplastic large cell lymphoma (pcALCL) or CD30-expressing mycosis fungoides (MF) who have received prior systemic therapy.

"By participating in the FDA’s Real-Time Oncology Review process and working closely with the FDA, we are now able to make the ADCETRIS regimen available to previously untreated patients with CD30-expressing PTCL in an unprecedented less than two weeks after submission of our supplemental BLA," said Clay Siegall, Ph.D., President and Chief Executive Officer of Seattle Genetics. "The ECHELON-2 clinical trial demonstrated ADCETRIS plus CHP results in a superior outcome for patients when compared to current standard of care, CHOP. We want to thank the patients, physicians and their staff who participated in the ECHELON-2 trial, which supported this FDA approval."

The ECHELON-2 data will be presented at the American Society of Hematology (ASH) (Free ASH Whitepaper) 2018 Annual Meeting, on Monday, December 3, 2018, at 6:15 pm PT at the San Diego Convention Center in Room 6F in San Diego, Calif. Patients in ECHELON-2 were randomized to receive either a combination of ADCETRIS plus CHP or CHOP, a recognized standard of care for frontline PTCL. Results from the trial demonstrated that combination treatment with ADCETRIS plus CHP was superior to CHOP for progression free survival (PFS) as assessed by a Blinded Independent Central Review facility (BICR; hazard ratio=0.71; 95% CI, 0.54–0.93; p-value=0.011). This corresponds to a 29 percent reduction in the risk of progression, death, or receipt of subsequent anticancer chemotherapy to treat residual or progressive disease. The ADCETRIS plus CHP arm also demonstrated superior overall survival (OS), a key secondary endpoint, compared to CHOP (hazard ratio=0.66; 95% CI, 0.46-0.95; p-value=0.024). All other key secondary endpoints, including PFS in patients with sALCL (hazard ratio=0.59; 95% CI, 0.42-0.84; p-value=0.003), complete remission rate (68% vs 56%; p-value=0.007) and objective response rate (83% vs 72%; p-value=0.003) were statistically significant in favor of the ADCETRIS plus CHP arm.

The safety profile of ADCETRIS plus CHP in the ECHELON-2 trial was comparable to CHOP and consistent with the established safety profile of ADCETRIS in combination with AVD. The most common adverse events of any grade that occurred in at least 20 percent of patients in the ADCETRIS plus CHP arm were peripheral neuropathy, nausea, diarrhea, neutropenia, lymphopenia, fatigue, mucositis, constipation, alopecia, pyrexia, vomiting and anemia. Serious adverse reactions occurring in at least two percent of ADCETRIS plus CHP-treated patients included febrile neutropenia, pneumonia, pyrexia and sepsis. Based on ECHELON-2 clinical trial results, prophylactic growth factors (G-CSF) should be administered starting at cycle one for patients receiving ADCETRIS plus CHP for previously untreated PTCL.

ECHELON-2 Phase 3 Clinical Trial Design

The multi-center, randomized, double-blind, placebo-controlled phase 3 trial is investigating ADCETRIS plus CHP (cyclophosphamide, doxorubicin, prednisone) versus CHOP (cyclophosphamide, doxorubicin, vincristine, prednisone) as frontline therapy in patients with CD30-expressing peripheral T-cell lymphoma, also known as mature T-cell lymphoma. The primary endpoint is progression-free survival (PFS) per BICR facility assessment, with events defined as progression, death due to any cause, or receipt of subsequent anticancer chemotherapy to treat residual or progressive disease. Secondary endpoints include PFS in patients with systemic anaplastic large cell lymphoma (sALCL), complete remission rate, overall survival and objective response rate, in addition to safety. The trial was conducted at sites across North America, Europe and Asia and was designed to enroll 450 patients, approximately 75 percent of whom were to be diagnosed with sALCL. The ECHELON-2 trial was conducted under a Special Protocol Assessment (SPA) agreement from the U.S. Food and Drug Administration (FDA) and the trial also received European Medicines Agency (EMA) scientific advice.

About T-Cell Lymphomas

Lymphoma is a general term for a group of cancers that originate in the lymphatic system. There are two major categories of lymphoma: Hodgkin lymphoma and non-Hodgkin lymphoma. There are more than 60 subtypes of non-Hodgkin lymphomas which are broadly divided into two major groups: B-cell lymphomas, which develop from abnormal B-lymphocytes, and T-cell lymphomas, which develop from abnormal T-lymphocytes. There are many different forms of T-cell lymphomas, some of which are extremely rare. T-cell lymphomas can be aggressive (fast-growing) or indolent (slow-growing). PTCL accounts for approximately 10 percent of the estimated 74,680 people diagnosed with non-Hodgkin lymphoma in the U.S. in 2018.1

About ADCETRIS (brentuximab vedotin)

ADCETRIS is being evaluated broadly in more than 70 clinical trials in CD30-expressing lymphomas. These include the recently completed phase 3 ECHELON-2 trial in frontline peripheral T-cell lymphomas (also known as mature T-cell lymphoma), the completed phase 3 ECHELON-1 trial in previously untreated Hodgkin lymphoma, the completed phase 3 ALCANZA trial in cutaneous T-cell lymphoma, and the ongoing CHECKMATE 812 trial of ADCETRIS in combination with Opdivo (nivolumab) for relapsed/refractory Hodgkin lymphoma.

ADCETRIS is an ADC comprising an anti-CD30 monoclonal antibody attached by a protease-cleavable linker to a microtubule disrupting agent, monomethyl auristatin E (MMAE), utilizing Seattle Genetics’ proprietary technology. The ADC employs a linker system that is designed to be stable in the bloodstream but to release MMAE upon internalization into CD30-expressing tumor cells.

ADCETRIS injection for intravenous infusion has received FDA approval for six indications in adult patients with: (1) previously untreated systemic anaplastic large cell lymphoma (sALCL) or other CD30-expressing peripheral T-cell lymphomas (PTCL), including angioimmunoblastic T-cell lymphoma and PTCL not otherwise specified, in combination with cyclophosphamide, doxorubicin, and prednisone, (2) previously untreated Stage III or IV classical Hodgkin lymphoma (cHL), in combination with doxorubicin, vinblastine, and dacarbazine, (3) cHL at high risk of relapse or progression as post-autologous hematopoietic stem cell transplantation (auto-HSCT) consolidation, (4) cHL after failure of auto-HSCT or failure of at least two prior multi-agent chemotherapy regimens in patients who are not auto-HSCT candidates, (5) sALCL after failure of at least one prior multi-agent chemotherapy regimen, and (6) primary cutaneous anaplastic large cell lymphoma (pcALCL) or CD30-expressing mycosis fungoides (MF) who have received prior systemic therapy.

Health Canada granted ADCETRIS approval with conditions for relapsed or refractory Hodgkin lymphoma and sALCL in 2013, and non-conditional approval for post-autologous stem cell transplantation (ASCT) consolidation treatment of Hodgkin lymphoma patients at increased risk of relapse or progression.

ADCETRIS received conditional marketing authorization from the European Commission in October 2012. The approved indications in Europe are: (1) for the treatment of adult patients with relapsed or refractory CD30-positive Hodgkin lymphoma following ASCT, or following at least two prior therapies when ASCT or multi-agent chemotherapy is not a treatment option, (2) the treatment of adult patients with relapsed or refractory sALCL, (3) for the treatment of adult patients with CD30-positive Hodgkin lymphoma at increased risk of relapse or progression following ASCT, and (4) for the treatment of adult patients with CD30-positive cutaneous T-cell lymphoma (CTCL) after at least one prior systemic therapy.

ADCETRIS has received marketing authorization by regulatory authorities in 72 countries for relapsed or refractory Hodgkin lymphoma and sALCL. See select important safety information, including Boxed Warning, below.

Seattle Genetics and Takeda are jointly developing ADCETRIS. Under the terms of the collaboration agreement, Seattle Genetics has U.S. and Canadian commercialization rights and Takeda has rights to commercialize ADCETRIS in the rest of the world. Seattle Genetics and Takeda are funding joint development costs for ADCETRIS on a 50:50 basis, except in Japan where Takeda is solely responsible for development costs.

On November 16, 2018 ArQule, Inc. (Nasdaq: ARQL) reported the presentation of clinical and preclinical data on ARQ 751 in three poster presentations at the 30th EORTC/AACR/NCI Symposium held from November 13 to 16, 2018 in Dublin, Ireland (Press release, ArQule, NOV 16, 2018, View Source [SID1234531401]). The data presented highlight clinical data from ARQ 751-101, a Phase 1 study in adult patients with refractory and/or metastatic tumors that harbor AKT, PI3K or PTEN genetic alterations, and preclinical data on ARQ 751 in combination with other agents.

Clinical data highlights and key conclusions include:

1. A Phase 1 Dose Escalation Study of ARQ 751 in Adult Patients with Advanced Solid Tumors with AKT1, 2, 3 Genetic Alterations, Activating PI3K Mutations, PTEN-null, or Other Known Actionable PTEN Mutations

ARQ 751 demonstrated manageable toxicity at doses from 5 mg QD to 75 mg QD, and the recommended Phase 2 dose was determined to be 75 mg QD
Evidence of clinical activity was observed with two partial responses in ER+/PR+/HER2- stage IV breast cancer patients, one with PTEN C296fs*2 mutation, one with PIK3CA H1047R mutation, 11 patients had stable disease
The data support continued development of ARQ 751 as a monotherapy or in combination with other anti-cancer agents due to its manageable safety profile and preliminary evidence of biological activity
"ARQ 751, as a highly specific allosteric AKT inhibitor, holds great potential in treating patients with solid tumors harboring mutations in the AKT/PI3K/PTEN pathways," said Brian Schwartz, M.D., Chief Medical Officer of ArQule. "The presented data are very encouraging and demonstrate both preliminary signs of clinical activity and a favorable safety profile while also determining the recommended Phase 2 dose. At ArQule, we are committed to developing genetically targeted cancer treatments to provide effective new treatment options for patients, particularly those with advanced or relapsed disease, and look forward to advancing the ARQ 751 clinical program."

Preclinical data highlights include:

2. Combination of the AKT inhibitor ARQ 751 with Immune Checkpoint Inhibitor and Other Therapeutic Agents

In preclinical cellular models, ARQ 751 exerted greater anti-proliferative and biochemical effects when in combination with multiple therapeutic agents including an ER antagonist, aromatase inhibitor, androgen receptor antagonist and a BTK inhibitor
In an in vivo colon cancer animal model, ARQ 751 in combination with an anti-PD-1 antibody exhibited superior anti-tumor activity compared to single agents
3. Miransertib and ARQ 751 exhibit superior cell-death-inducing properties compared to other AKT inhibitors and can overcome resistance to other allosteric AKT inhibitors

ArQule’s AKT inhibitors, miransertib and ARQ 751 showed superior activity in comparison to other allosteric and ATP-competitive AKT inhibitors currently in clinical development
Miransertib and ARQ 751 have the potential to overcome some mechanisms of resistance to AKT inhibitors
Miransertib and ARQ 751 in combination with ATM inhibition demonstrated synergistic effects
Dr. Shubham Pant, MD, Associate Professor in the Department of Investigational Cancer Therapeutics at MD Anderson Cancer Center, said "AKT inhibitors have significant potential to treat a broad range of solid tumors in molecularly defined patient populations. The presented data show that ARQ 751 exhibits unique properties that differentiate it from other AKT inhibitors. It is our hope that by combining ARQ 751 with a broad spectrum of therapeutic agents, including hormonal agents, we could provide new opportunities for combinatorial interventions in oncology."

All posters presented by ArQule at the EORTC/AACR/NCI Symposium are available on the company’s website at View Source

About ARQ 751
ARQ 751 is an orally bioavailable, selective small molecule inhibitor of the AKT serine/threonine kinase. The AKT pathway when abnormally activated is implicated in multiple oncogenic processes such as cell proliferation and apoptosis. This pathway has emerged as a target of potential therapeutic relevance for compounds that inhibit its activity, which has been linked to a variety of cancers as well as to select non-oncology indications. ARQ 751 is currently in a Phase 1 study in adult patients with refractory and/or metastatic tumors that harbor genetic alterations along the AKT pathway.

About Miransertib
Miransertib (ARQ 092) is an orally bioavailable, selective, pan-AKT (protein kinase B) inhibitor that potently inhibits AKT1, 2 and 3 isoforms. Dysregulation of AKT has been implicated in a variety of rare overgrowth diseases and cancers; however, there are currently no approved inhibitors of AKT. AKT inhibitors, either as single agent or combination therapy, show significant promise in molecularly defined patient populations. Miransertib is currently in a Phase 1/2 company-sponsored study for PIK3CA-Related Overgrowth Spectrum (PROS), a Phase 1 study for ultra-rare Proteus syndrome conducted by the National Institutes of Health (NIH/NHGRI), and a Phase 1b study in combination with the hormonal therapy, anastrozole, in patients with advanced endometrial cancer with AKT and PI3K mutations. Miransertib has been granted Rare Pediatric Disease Designation and Fast Track Designation by the U.S. Food and Drug Administration (FDA), as well as Orphan Designation by the FDA and European Medicines Agency in the rare overgrowth disease, Proteus syndrome.
