On June 1, 2018 TESARO, Inc. (NASDAQ:TSRO), an oncology-focused biopharmaceutical company, reported the National Institute for Health and Care Excellence (NICE) will make ZEJULA (niraparib), the first PARP inhibitor shown to be effective in patients with a BRCA mutation as well as those without a BRCA mutation, available to women in England and Wales with recurrent platinum-sensitive ovarian cancer via the Cancer Drugs Fund (CDF)1 (Press release, TESARO, JUN 1, 2018, View Source [SID1234527048]). NICE has recommended ZEJULA via the CDF for women with a BRCA mutation who have received two lines of chemotherapy and in women without a BRCA mutation who have received two or more lines of chemotherapy.

"At TESARO, we continue to globalize our mission and bring transformative therapies to patients. We are pleased that NICE will now provide more women with recurrent ovarian cancer in England and Wales access to ZEJULA through the CDF," said Orlando Oliveira, Senior Vice President and General Manager, TESARO International. "Through close partnership with both NICE and NHS, TESARO can now offer ZEJULA as an option for second-line maintenance treatment, regardless of a patient’s BRCA status."

The CDF is a source of funding for cancer drugs in England, providing patients access to promising new oncology treatments while NHS England and NICE analyze any additionally requested data to inform a final reimbursement decision on a new treatment or indication. Overall survival data for ZEJULA are not yet available, and as a result NICE has recommended ZEJULA for use within the CDF while further data are collected2. Interim funding is provided via the CDF, giving patients access to the treatment through a managed access arrangement.

"Recurrent ovarian cancer is an aggressive form of cancer where a key goal of treatment is to keep women in remission and off chemotherapy for as long as possible – allowing them the best chance for a good quality of life," said Jonathan Ledermann, Professor of Medical Oncology at the University College London Cancer Institute. "ZEJULA offers the chance to delay this cancer from returning or progressing for months, and possibly years in some cases. It is a significant step forward. Crucially, this decision opens the door for many women who, until now, have not had the option of maintenance treatment with a PARP inhibitor."

About Ovarian Cancer
In the UK, ovarian cancer has the highest mortality rate of all gynecological cancers3. It has one of the highest incidence rates in Europe4 with survival rates among the lowest5. The rate of newly diagnosed cases of ovarian cancer in the UK is 16 per 100,000 of the population compared to the European average of 12.6 per 100,0005. Every year 4,100 women lose their lives to ovarian cancer – 11 women every day6.

The most common symptoms of ovarian cancer include abdominal or pelvic pain, bloating, difficulty eating, and urinary urgency, all of which are commonly associated with less serious conditions. 60% of women with ovarian cancer are diagnosed in an advanced stage7, when prognosis is poor. Although significant progress has been made in treatment of ovarian cancer, the disease recurs in approximately 85% of women with advanced ovarian cancer8, at which point it may be incurable9,10. Recurrent ovarian cancer is the sixth most common cause of cancer death among women and has the highest mortality rate of all gynecological cancers.

About ZEJULA (niraparib)
Niraparib is marketed in the United States and Europe under trade name ZEJULA. ZEJULA is a poly(ADP-ribose) polymerase (PARP) inhibitor indicated for the maintenance treatment of adult patients with recurrent epithelial ovarian, fallopian tube, or primary peritoneal cancer who are in a complete or partial response to platinum-based chemotherapy. In preclinical studies, ZEJULA concentrates in the tumor relative to plasma, delivering greater than 90% durable inhibition of PARP 1/2 and a persistent antitumor effect.

ZEJULA is approved in Europe as a monotherapy for the maintenance treatment of adult patients with platinum-sensitive relapsed high grade serous epithelial ovarian, fallopian tube, or primary peritoneal cancer who are in complete response (CR) or partial response (PR) to platinum-based chemotherapy. The approval was based on data from the clinically rigorous ENGOT-OV16/NOVA trial, a double-blind, placebo-controlled, international Phase 3 study of ZEJULA that enrolled 553 patients with recurrent ovarian cancer who had achieved either a PR or CR to their most recent platinum-based chemotherapy. ZEJULA is the first once-daily, oral poly (ADP-ribose) polymerase (PARP)1/2 inhibitor to be approved in Europe that does not require BRCA mutation or other biomarker testing.

The primary endpoint of the trial was progression free survival (PFS). Approximately two-thirds of study participants did not have germline BRCA mutations. Progression in the NOVA study was determined by a robust, unbiased, blinded central review to be the earlier of radiographic or clinical progression. ZEJULA significantly increased PFS in patients with or without germline BRCA mutations as compared to the control arm. Treatment with ZEJULA reduced the risk of disease progression or death by 73% in patients with germline BRCA mutations (hazard ration (HR) 0.27) and by 55% in patients without germline BRCA mutations (HR 0.45). The magnitude of benefit was similar for patients entering the trial with a PR or a CR.

The approved starting dose of ZEJULA is 300 milligrams once per day. According to the European summary of product characteristics (SmPC), in patients below 58 kilograms, a starting dose of 200 milligrams once per day may be considered. The most commonly administered dose of ZEJULA over the course of the Phase 3 NOVA clinical trial was 200 milligrams once per day, following dose modification. Further exploratory analyses of the NOVA study indicated that individual dose modification maintained efficacy and reduced the rate of new adverse events.11

ZEJULA (niraparib) Select Important Safety Information
Myelodysplastic Syndrome/Acute Myeloid Leukemia (MDS/AML) was reported in patients treated with ZEJULA in some clinical studies. Discontinue ZEJULA if MDS/AML is confirmed. Hematologic adverse reactions (thrombocytopenia, anemia and neutropenia) have been reported in patients treated with ZEJULA. Do not start ZEJULA until patients have recovered from hematological toxicity caused by previous chemotherapy (≤ Grade 1). Monitor complete blood counts weekly for the first month, monthly for the next 11 months of treatment, and periodically after this time.

Hypertension and hypertensive crisis have been reported in patients treated with ZEJULA. Monitor blood pressure and heart rate monthly for the first year and periodically thereafter during treatment with ZEJULA. Closely monitor patients with cardiovascular disorders, especially coronary insufficiency, cardiac arrhythmias, and hypertension.

Based on its mechanism of action, ZEJULA can cause fetal harm. Advise females of reproductive potential of the potential risk to a fetus and to use effective contraception during treatment and for six months after receiving the final dose. Because of the potential for serious adverse reactions in breastfed infants from ZEJULA, advise a lactating woman not to breastfeed during treatment with ZEJULA and for one month after receiving the final dose.

On June 1, 2018 Elios Therapeutics, a biopharmaceutical company developing innovative autologous, particle-delivered, dendritic cell cancer vaccines, reported interim data from the ongoing prospective, randomized, double-blind, placebo-controlled Phase IIb clinical trial of the TLPLDC (tumor lysate, particle-loaded, dendritic cell) vaccine in patients with Stage III and IV, resected melanoma will be presented at the American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Annual Meeting on June 4, 2018 in Chicago, Illinois (Abstract # 9525) (Press release, Orbis Health Solutions, JUN 1, 2018, View Source [SID1234529912]).

The planned interim analysis was conducted after the first 120 patients enrolled in the trial had been randomized and treated for at least 6 months. In the per treatment population, TLPLDC showed a meaningful 32 percent reduction in the relative risk of recurrence (TLPLDC 29.4 percent vs. placebo 43.3 percent, p = 0.07) with a median follow-up of 12.6 months. There was no difference in recurrence in the intent-to-treat population (TLPLDC 56.6 percent, placebo 54.1 percent, p=0.65) with 11.9 months median follow-up. Overall, TLPLDC was safe and well-tolerated. In the study, only 33 percent of participants experienced any adverse event, and 98.6 percent of those were grade 1 and 2 events that included injection site reactions and flu-like symptoms. No serious adverse events were reported.

"The interim data evaluating the TLPLDC vaccine as an adjuvant treatment to prevent melanoma recurrences are very encouraging, suggesting clinical activity and demonstrating an attractive safety profile," said George E. Peoples, M.D., chief medical officer at Elios Therapeutics. "These data, combined with the recently reported results of our open label Phase II study demonstrating the synergistic effects of the TLPLDC vaccine in combination with checkpoint inhibitors, suggest a strong rationale for further clinical development in a Phase III program."

Detailed results from the ongoing Phase IIb study evaluating TLPLDC will be presented on Monday, June 4, 2018:

Abstract 9525 (Poster #352): Interim analysis of a prospective, randomized, double-blind, placebo-controlled, Phase IIb trial of the TLPLDC vaccine to prevent recurrence in resected Stage III or IV melanoma patients
Presenter: John W. Myers, M.D., San Antonio Military Medical Center, Houston, TX
Data/Time: Monday, June 4, 2018 from 1:15 PM – 4:45 PM CDT
Session: Melanoma/Skin Cancers Poster Session – Hall A
About the Study Design
Elios Therapeutics is conducting a prospective, randomized, double-blind, placebo-controlled Phase IIb trial to evaluate the safety and efficacy of TLPLDC in patients with resected Stage III and IV melanoma. The primary endpoint is 2 year disease-free survival (DFS).

In the study, 120 participants were randomized (2:1) to receive either TLPLDC vaccine or placebo to prevent recurrence. TLPLDC or placebo vaccines were initiated within 3 months of completion of standard of care (SoC) therapies and were given at 0, 1, 2, 6, 12, and 18 months. Study participants were followed for recurrence per SoC. The interim analysis was pre-specified at 6 months from randomization of the 120th study participant. Survival analysis was performed on the intent-to-treat and per treatment populations. The latter excludes early recurrences during the primary vaccine series (up to 6 months).

About TLPLDC
The TLPLDC (tumor lysate, particle-loaded, dendritic cell) vaccine is an autologous, personalized, therapeutic cancer vaccine designed to stimulate the immune system to recognize tumor cells and fight a patient’s specific cancer. TLPLDC is made from a patient’s own tumor and dendritic cells – the most potent antigen-presenting cells in the body. Once TLPLDC is injected, the tumor lysate-loaded dendritic cells present the tumor antigens to the immune system, stimulating the induction of tumor-specific, activated T cells that are able to find and destroy tumor cells that may remain in the body. TLPLDC is currently being studied as a monotherapy and in combination with SoC checkpoint inhibitor therapy in a Phase IIb clinical trial for the treatment of late-stage melanoma at leading academic cancer centers in the United States.

On June 1, 2018 Agios Pharmaceuticals, Inc. (NASDAQ:AGIO), a leader in the field of cellular metabolism to treat cancer and rare genetic diseases, reported the first data from the ongoing Phase 1 study evaluating single agent AG-881 in advanced glioma and other solid tumors (Press release, Agios Pharmaceuticals, JUN 1, 2018, View Source [SID1234527032]). The data were featured in an oral presentation at the American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Annual Meeting. AG-881 is an investigational, oral, selective, potent inhibitor of mutant isocitrate dehydrogenase-1 (IDH1) and IDH2 enzymes, which was designed for enhanced brain penetrance for development in IDH-mutant glioma.

"IDH mutant glioma is a distinct disease where patients are typically diagnosed in their thirties and forties and endure a deteriorating quality of life from the side effects associated with multiple rounds of surgery, radiation and chemotherapy and ultimately die of their disease," said Ingo Mellinghoff, M.D., Memorial Sloan Kettering Cancer Center, an investigator for the study. "The AG-881 Phase 1 dose-escalation data are encouraging, as they demonstrate a favorable safety profile at lower dose levels and show signals of clinical activity that support further evaluation of the role of inhibiting mutant IDH in low-grade glioma."

"With no curative or approved targeted therapies for low-grade glioma and a poor long-term prognosis, we are committed to exploring the novel mechanism of action of our IDH inhibitors in this indication," said Chris Bowden, M.D., chief medical officer at Agios. "Data from our ivosidenib and AG-881 Phase 1 trials and the ongoing perioperative study, combined with feedback from regulators and the neurology community, will inform our pivotal development plan."

The ongoing Phase 1 dose-escalation trial is assessing the safety and tolerability of AG-881 in IDH1/2 mutant advanced solid tumors, including glioma. As of the March 29, 2018 data cut-off, 93 patients (52 with glioma and 41 with other solid tumors) have been treated with single agent AG-881. Enrollment is complete and 17 glioma patients and 1 non-glioma solid tumor patient remain on treatment. Study design, status and baseline characteristics for the 52 glioma patients are reported below.

Forty-eight percent of patients (n=25) had World Health Organization (WHO) classified Grade 2 tumors, 42% (n=22) had Grade 3 tumors, 8% (n=4) had Grade 4 tumors and 2% (n=1) was unknown.
Ninety-two percent of patients (n=48) had an IDH1 mutation and 6% (n=3) had an IDH2 mutation. One patient did not have a biopsy but was confirmed as IDH mutant positive due to 2-HG elevation by magnetic resonance spectroscopy (MRS).
The median age of these patients is 42.5 years (ranging from 16-73 years).
Patients received a median of two prior systemic therapies (ranging from one to six).
— Seventy-three percent of patients (n=38) had previously received temozolomide and 58% percent (n=30) had previously received radiotherapy.
Patients received daily doses of AG-881 ranging from 10 mg to 300 mg.
The median treatment duration was seven months (ranging from 0-27 months) for all glioma patients, 12 months (ranging from 1-27 months) for non-enhancing glioma and 3 months (ranging from 0- 27 months) for patients with enhancing disease.
Safety Data

The safety analysis conducted for all 93 treated patients as of the data cut-off demonstrated that AG-881 has a favorable safety profile at dose levels below 100 mg.

The majority of adverse events (AEs) reported by investigators were mild to moderate, with the most common (>33%) being fatigue, nausea, increases in alanine aminotransferase (ALT) and increases in aspartate aminotransferase (AST).
Grade 3 or higher AEs were observed in 33% of all patients (n=31).
Dose limiting toxicities (DLTs) of Grade 2 or higher elevated transaminases occurred in five glioma patients at the higher dose levels (≥100 mg) and resolved to Grade ≤1 with dose modification or discontinuation. There were no treatment-related on-treatment deaths.
A maximum tolerated dose (MTD) was not reached by Bayesian model; the doses chosen for further clinical development were based on safety, pharmacokinetics and pharmacodynamics data.

Efficacy Data

Efficacy data from the 52 glioma patients (23 with non-enhancing and 29 with enhancing disease) as of the data cut-off showed:

One patient with non-enhancing disease and a 1p19q co-deletion had a sustained minor response according to the investigator by Response Assessment in Neuro-Oncology for low grade glioma (RANO-LGG) and remains on treatment.
Seventy-five percent of patients (n=39) had a best response of stable disease, including 20 patients with non-enhancing disease.
Thirty-five percent of patients (n=18, including 13 patients with non-enhancing disease) remained on treatment for ≥1 year.
Efficacy data from the 41 patients with non-glioma solid tumors as of the data cut-off showed:

One patient with cholangiocarcinoma had a partial response, 37% of patients (n=15) had stable disease and 44% (n=18) had progressive disease.
The median treatment duration was 2 months (ranging from 0-18 months).
Ongoing Perioperative Study in Glioma
A perioperative ‘window’ trial with ivosidenib and AG-881 (10 mg and 50 mg) in up to 45 IDH1m non-enhancing low-grade glioma patients is ongoing. The goal of the trial is to confirm CNS penetrance and tumor 2-HG suppression of ivosidenib and AG-881 as part of the strategy to finalize pivotal development plans by year-end 2018.

About Glioma
Glioma presents in varying degrees of tumor aggressiveness, ranging from slower growing (low grade glioma) to rapidly progressing (high grade glioma-Glioblastoma Multiforme). Common symptoms include seizures, memory disturbance, sensory impairment and neurologic deficits. The long-term prognosis is poor with a five-year survival rate of 33 percent. Approximately 11,000 low-grade glioma patients are diagnosed annually in the U.S. and EU and approximately 80 percent have an IDH1 mutation.

"The abstract being presented at ASCO (Free ASCO Whitepaper) 2018 highlights the progress of our clinical program and the potential of INT230-6 as a medicine for multiple cancer types," said Lewis H. Bender, President and CEO of Intensity Therapeutics, Inc. "We are pleased to describe our current clinical study evaluating INT230-6 at this prestigious meeting, which to date has had no dose limiting toxicities following treatments to fourteen patients having nine different solid tumor types."

Details of the trials-in-progress abstract accepted for presentation at the 2018 ASCO (Free ASCO Whitepaper) Annual Meeting are below.

Abstract TPS2609: Phase 1/2 trial evaluating intratumoral administration of INT230-6 alone and in combination with an anti-PD1 antibody for advanced malignancies.

Presenter: Yada Kanjanapan, MBBS
Session: Developmental Therapeutics—Clinical Pharmacology and Experimental Therapeutics
Clinical Trial Registry Number: NCT03058289
Date/Time: June 4, 2018, 8:00 AM-11:30 AM
Location: Hall A; Poster Board Number: 428b

About INT230-6
INT230-6 is a novel, anti-cancer drug for direct intratumoral injection. The product contains potent anti-cancer agents that disperse throughout tumors and diffuse into cancer cells. INT230-6 was identified from Intensity’s DfuseRxSM platform and is being evaluated in a clinical trial; IT 01. In preclinical studies INT230-6 administration eradicated tumors by a combination of direct tumor kill coupled with recruitment of dendritic cells to the tumor micro-environment that induced anti-cancer T-cell activation. Treatment with INT230-6 in in vivo models of severe cancer resulted in substantial improvement in overall survival compared to standard therapies. Further, INT230-6 provided complete responder animals with long-term, durable protection from multiple re-inoculations of the initial cancer and resistance to other cancers. In mouse models the drug has shown strong synergy with checkpoint blockage including anti-PD-1 and anti-CTLA4 antibodies.

About Study IT-01
IT-01 is entitled A Phase 1/2 Safety Study of Intratumorally Administered INT230-6 in Adult Subjects with Advanced Refractory Cancers. The trial aims to enroll approximately 60 patients with different types advanced solid tumor malignancies in a multicycle dosing regimen. The study is currently recruiting in the U.S. and Canada with plans to open additional sites in multiple countries. The study’s primary objective is to assess the safety and tolerability of multiple intratumoral doses of INT230-6 with or without an anti-PD-1 or other checkpoint blockade antibodies. Secondary assessments are the measurement of injected and bystander tumor responses, and determination of the systemic pharmacokinetic profile of multiple doses of INT230-6’s drug substances after single and then multiple intratumoral injections. Exploratory analysis will characterize patient outcome, as well as evaluate various tumor and anti-tumor immune response biomarkers that may correlate with response. The trial includes several adaptive components that will allow for adjustments in patient groups, dosing schedule and dose volumes administered. Data will be used to assess the progression free and overall survival in subjects receiving INT230-6. Further information can be found at www.clinicaltrials.gov (NCT#03058289).
