On June 4, 2018 Array BioPharma Inc. (NASDAQ: ARRY) reported updated results from the Phase 3 COLUMBUS trial in BRAF-mutant advanced melanoma (Press release, Array BioPharma, JUN 4, 2018, View Source [SID1234527132]). The results showed median overall survival (mOS) was 33.6 months for patients treated with the combination of encorafenib and binimetinib compared to 16.9 months for patients treated with vemurafenib as a monotherapy. The combination reduced the risk of death compared to treatment with vemurafenib alone [hazard ratio (HR) of 0.61, [95% CI 0.47, 0.79, p <0.0001]. The observed efficacy of vemurafenib in the control arm is also consistent with historical data, providing an additional benchmark for validating the patient population and results observed in COLUMBUS. [1, 2] Further, the two-year OS with combination therapy was 58%. These results will be part of an oral presentation today at the American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) annual meeting in Chicago, Illinois and have been selected for the "Best of ASCO (Free ASCO Whitepaper)" program.

Importantly, the presentation will include data showing limited use of post-trial immunotherapy, which is consistent with other published pivotal trials of BRAF and MEK-inhibitors in BRAF-mutant advanced melanoma. [1, 3]

"The data presented today at ASCO (Free ASCO Whitepaper) demonstrate that the use of subsequent immunotherapies was consistent across treatment groups, indicating that these subsequent treatments are unlikely to have contributed to the observed differences in survival," said Keith T. Flaherty, M.D., Director of the Termeer Center for Targeted Therapy, Massachusetts General Hospital Cancer Center and Professor of Medicine, Harvard Medical School. "This further suggests encorafenib and binimetinib could be a promising new treatment option for patients with BRAF-mutant advanced melanoma."

Additionally, the updated median progression-free survival (mPFS) results for patients treated with the combination of encorafenib and binimetinib remained consistent with what was previously reported at 14.9 months versus 7.3 months for patients treated with vemurafenib [HR= 0.51, 95% CI 0.39-0.67; p<0.0001].

As previously reported, the combination of encorafenib and binimetinib was generally well-tolerated. Grade 3/4 adverse events (AEs) that occurred in more than 5% of patients receiving the combination were increased gamma-glutamyltransferase (GGT) (9%), increased blood creatine phosphokinase (CK) (7%) and hypertension (6%). The incidence of selected any grade AEs of special interest, defined based on toxicities commonly associated with commercially available BRAF+MEK-inhibitor treatments for patients receiving the combination of encorafenib and binimetinib included: rash (22%), serous retinopathy including retinal pigment epithelial detachment (20%), pyrexia (18%) and photosensitivity (5%). Full safety results of COLUMBUS Part 1 were published in The Lancet Oncology.

A PDF of the ASCO (Free ASCO Whitepaper) COLUMBUS presentation will be available on Array’s website.

In the COLUMBUS trial, eligible patients were randomized 1:1:1 to receive the combination of encorafenib, 450 mg daily, plus binimetinib, 45 mg twice daily, encorafenib 300 mg daily as a monotherapy, or vemurafenib 960 mg twice daily as a monotherapy.

Data from Array’s partnered programs with AstraZeneca, Genentech and Loxo Oncology were also presented on the Array-invented molecules selumetinib, ipatasertib and LOXO-292, respectively.

Array will host an encore webcast presentation of the COLUMBUS trial data.

About Melanoma
Metastatic melanoma is the most serious and life-threatening type of skin cancer and is associated with low survival rates. [4, 5] There are about 200,000 new cases of melanoma diagnosed worldwide each year, approximately half of which have BRAF mutations, a key target in the treatment of metastatic melanoma. [4, 6, 7, 8]

About COLUMBUS
The COLUMBUS trial (NCT01909453) is a two-part, international, randomized, open label Phase 3 trial evaluating the efficacy and safety of the combination of encorafenib and binimetinib compared to vemurafenib and encorafenib monotherapy in 921 patients with locally advanced, unresectable or metastatic melanoma with BRAFV600 mutation. Prior immunotherapy treatment was allowed. Over 200 sites across North America, Europe, South America, Africa, Asia and Australia participated in the trial. Patients were randomized into two parts:

In Part 1, 577 patients were randomized 1:1:1 to receive the combination of encorafenib 450 mg daily and binimetinib 45 mg twice daily (COMBO450), encorafenib, 300 mg daily alone (ENCO 300), or vemurafenib, 960 mg twice daily alone. The dose of encorafenib in the combination arm is 50% higher than the single agent maximum tolerated dose of 300 mg. A higher dose of encorafenib was possible due to improved tolerability when combined with binimetinib. The primary endpoint for the COLUMBUS trial was an mPFS comparison of the COMBO450 arm versus vemurafenib. mPFS is determined based on tumor assessment (RECIST version 1.1 criteria) by a Blinded Independent Central Review (BICR). Secondary endpoints include a comparison of the mPFS of COMBO450 arm to that of ENCO300 and a comparison of overall survival (OS) in patients treated in the COMBO450 arm to that of vemurafenib alone. Results from Part 1 of the COLUMBUS trial, previously published in The Lancet Oncology May 2018, showed that COMBO450 more than doubled mPFS in patients with advanced BRAF-mutant melanoma, with a mPFS of 14.9 months compared with 7.3 months observed with vemurafenib [HR 0.54, (95% CI 0.41-0.71, p<0.0001)]. In the secondary mPFS comparison of COMBO450 to ENCO300, ENCO300 demonstrated a mPFS of 9.6 months [HR 0.75, (95% CI 0.56-1.00, p=0.051)].

In Part 2, 344 patients were randomized 3:1 to receive encorafenib 300 mg daily plus binimetinib 45 mg twice daily (COMBO300) or ENCO300. Part 2 was designed to provide additional data to help evaluate the contribution of binimetinib to the combination of encorafenib and binimetinib.
As the secondary endpoint comparison of mPFS between the COMBO450 arm and ENCO300 arm in Part 1 did not achieve statistical significance, the protocol specified analysis of OS is descriptive.

About Encorafenib and Binimetinib
BRAF and MEK are key protein kinases in the MAPK signaling pathway (RAS-RAF-MEK-ERK). Research has shown this pathway regulates several key cellular activities including proliferation, differentiation, survival and angiogenesis. Inappropriate activation of proteins in this pathway has been shown to occur in many cancers including melanoma and colorectal cancer. Encorafenib is a late-stage small molecule BRAF inhibitor and binimetinib is a late-stage small molecule MEK inhibitor, both of which target key enzymes in this pathway. Encorafenib and binimetinib are being studied in clinical trials in advanced cancer patients, including the Phase 3 COLUMBUS trial and the Phase 3 BEACON CRC trial.

Array BioPharma has exclusive rights to encorafenib and binimetinib in the U.S. and Canada. Array has granted Ono Pharmaceutical exclusive rights to commercialize both products in Japan and South Korea and Pierre Fabre exclusive rights to commercialize both products in all other countries, including Europe, Asia and Latin America. Encorafenib and binimetinib are investigational medicines and are not currently approved in any country.

On June 4, 2018 NewLink Genetics Corporation (NASDAQ:NLNK) reported that data from two Phase 2 studies of indoximod, used in combination with other agents, were presented at the 2018 American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Annual Meeting (Press release, NewLink Genetics, JUN 4, 2018, View Source [SID1234527148]).

"Our data in advanced melanoma suggest that indoximod in combination with checkpoint blockade shows encouraging response rates potentially in both PD-L1 positive and negative patients," said Charles J. Link, Jr, MD, Chairman and Chief Executive Officer. "We wish to thank the patients and their caregivers who participated in both of these studies."

Indoximod in combination with checkpoint inhibition in advanced melanoma
Results from a single-arm Phase 2 study of indoximod in combination with checkpoint inhibitors for patients with advanced melanoma were presented today by Yousef Zakharia, MD, Assistant Professor of Medicine, Division of Hematology, Oncology and Blood & Marrow Transplantation at the University of Iowa and Holden Comprehensive Cancer Center.

In this study, of 102 total patients enrolled, 101 patients with advanced melanoma were treated with indoximod plus standard-of-care checkpoint inhibition as approved for melanoma. 70 patients with cutaneous or mucosal melanoma were treated with pembrolizumab plus indoximod and had an on-treatment imaging, meeting the per-protocol, pre-specified definition of evaluable for efficacy. Of the remaining 32 patients, 15 had uveal melanoma, 4 received ipilimumab, 4 received nivolumab, and one patient was never treated. In addition, 8 patients came off study prior to the first on-treatment imaging study. The full data set, including the expanded biopsy cohort, is provided on the company’s website in the "Posters & Presentations" section under the "Investors & Media" tab.
Key findings from the 70 evaluable for efficacy patients presented from the study include:
–
ORR for combination therapy of 56%
–
CR of 19%
–
Median PFS of 12.4 months
–
PD-L1 ≥ 1% staining of 54% (22/41 patients with archival tissue)
–
ORR by PD-L1 status
◦
PD-L1 (+) patients: ORR of 77%
◦
PD-L1 (-) patients: ORR of 42%
–
Combination was well tolerated

Indoximod in combination with chemotherapy in metastatic pancreatic cancer
Results from a Phase 2 study of indoximod plus chemotherapy for patients with metastatic pancreatic cancer were presented at ASCO (Free ASCO Whitepaper) by Nathan Bahary, MD, PhD, Associate Professor in the Division of Oncology and Medical Director of the Pancreatic Cancer Program at the University of Pittsburgh Medical Center. Key findings from this study show that the combination was well tolerated with a median Overall Survival (mOS) of 10.9 months and an Overall Response Rate (ORR) of 46.1%. Although the study did not meet the prespecified primary goal of a 30% decrease in the risk of death compared with historical controls, the combination demonstrated potentially promising activity with an immunologic correlation for response to therapy. These data may be found on the company’s website in the "Posters & Presentations" section under the "Investors & Media" tab.

About Indoximod
Indoximod is an investigational, orally available small molecule targeting the IDO pathway. The IDO pathway is a key immuno-oncology target involved in regulating the tumor microenvironment and immune escape. Indoximod is being evaluated in combination with treatment regimens including chemotherapy, radiation, checkpoint blockade and cancer vaccines across multiple indications such as AML, DIPG and melanoma.

On June 4, 2018 Rgenix, Inc., a clinical stage biopharmaceutical company developing first-in-class small molecule and antibody cancer therapeutics, reported it is presenting data on the safety, pharmacodynamics, and clinical activity from the dose escalation stage of the ongoing Phase Ia/b trial of RGX-104, an oral small molecule immunotherapy that targets the liver X receptor (LXR) (Press release, Rgenix, JUN 4, 2018, View Source [SID1234527164]).

In a poster presentation of an abstract accepted for the 2018 Annual Meeting of the American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper), "Pharmacodynamic and clinical activity of RGX-104, a first-in-class immunotherapy targeting the liver-X nuclear hormone receptor (LXR), in patients with refractory malignancies", Rgenix showed the first-in-class compound to be capable of generating immunologic and anti-tumor activity.

RGX-104 is a small-molecule LXR agonist that modulates innate immunity by activating the ApoE gene. In murine models, the small molecule depletes myeloid derived suppressor cells (MDSCs) and stimulates dendritic cells (DCs), activating anti-tumor immunity as a single agent as well as in combination with adoptive T cell therapy or checkpoint inhibitors. The Phase 1a/b trial in progress is studying the therapy with regards to safety, efficacy, pharmacokinetics and pharmacodynamics. A total of 26 patients with a broad array of tumors have received RGX-104 at a range of dose levels and frequency as part of the dose escalation stage of the study.

RGX-104 was well tolerated across dose cohorts, with hyperlipidemia – an on target effect of LXR agonism – representing the most common adverse event. Robust ApoE target gene engagement was observed in patients, along with substantial MDSC depletion and DC stimulation in 12 of 17 evaluable patients. Activation of circulating PD-1+ T cells was observed in 11 of the 12 patients that experienced MDSC depletion.

One patient with a high-grade neuroendocrine malignancy with small cell features had a confirmed radiographic partial response with a 53% reduction in index hepatic metastases at the 160 mg BID dose. This response was associated with a greater than 12-fold increase in activated PD-1+ T cells. Additionally, seven patients had stable disease for durations of 8-16 weeks. The dose of 160 mg BID was chosen as the Recommended Phase 2 Dose, with robust pharmacodynamic effects on ApoE expression and relevant immune cell populations.

Masoud Tavazoie, MD, PhD, and Chief Executive Officer of Rgenix, said, "Today’s presentation illustrates the promise of our lead clinical candidate RGX-104. It enables us to move forward with our plans to study the compound in expansion cohorts as a single agent as well as in combination with a PD-1 inhibitor in patients with both checkpoint-inhibitor refractory and naïve tumors." Escalation and Expansion cohorts in the Phase 1b stage of the clinical trial are currently enrolling patients with epithelial ovarian carcinoma (EOC), melanoma, non-small cell lung cancer (NSCLC), small cell lung cancer (SCLC), renal cell cancer (RCC), bladder cancer (BLC), and triple negative breast cancer (TNBC).

On June 4, 2018 ERYTECH Pharma (Euronext:ERYP) (Nasdaq:ERYP), a clinical-stage biopharmaceutical company developing innovative therapies by encapsulating therapeutic drug substances inside red blood cells, reported that it will present pharmacodynamic characterization data from its Phase 2/3 trial of eryaspase (GRASPA) in combination with chemotherapy for the treatment of relapsed acute lymphoblastic leukemia (ALL) at the American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Annual Meeting, being held June 1-5, 2018 in Chicago, Illinois (Press release, ERYtech Pharma, JUN 4, 2018, View Source;p=RssLanding&cat=news&id=2352888 [SID1234527117]).

The European Phase 2/3 trial pharmacodynamic data will be presented during the poster session of the Hematologic Malignancies by Dr. Iman El-Hariry, Chief Medical Officer of ERYTECH and Dr. Philip Lorenzi,
Co-Director of the proteomics and metabolomics core facility at MD Andersen Cancer Center.

Poster Session: Pharmacodynamic Characterization of eryaspase (L-asparaginase Encapsulated in Red Blood Cells) in Combination with Chemotherapy in a Phase 2/3 Trial in Patients with Relapsed Acute Lymphoblastic Leukemia (NCT01518517).

Poster: 7049
Lead Author: Dr. Iman El Hariry
Poster Session: Hematologic Malignancies—Leukemia, Myelodysplastic Syndromes, and Allotransplant
Location: Hall A
Date: Monday, June 4
Time: 8:00 a.m. – 11:30 a.m.
This randomized Phase 2/3 study enrolled patients with relapsed ALL (n=80, age: 1-55 years), randomized to eryaspase or native ASNase in combination with chemotherapy. The study demonstrated prolonged asparaginase activity and marked reduction in allergic reactions with eryaspase, when compared with control native asparaginase. In addition, the study demonstrated an overall favorable safety profile as well as a higher complete remission (CR) rate with eryaspase.

The duration of asparagine (ASN) depletion was also evaluated in the study, and was inferior in the eryaspase arm, compared to control. These results are largely confounded by the lack of a reliable assay to measure ASN due to ex vivo depletion of ASN before the enzyme can be quenched. This can lead to over-estimation of ASN depletion with a free asparaginase enzyme, less so with an encapsulated enzyme. Importantly, ASN depletion ≤2 μM was maintained for approximately 7 days in 70% and 75% of patients, in the eryaspase and control arms, respectively. Of interest, correlation with complete remission rate suggests ASN depletion ≤2 μM may not be needed with eryaspase; rather, a level ≤7.55 μM at Day 6 may be sufficient.

On June 4, 2018 AstraZeneca and Merck & Co., Inc., Kenilworth, N.J., US (Merck: known as MSD outside the US and Canada) reported data, which showed clinical improvement in median radiologic progression-free survival (rPFS) with Lynparza (olaparib) in combination with abiraterone compared to abiraterone monotherapy, a standard of care, in metastatic castration-resistant prostate cancer (mCRPC) (Press release, AstraZeneca, JUN 4, 2018, View Source [SID1234527133]). Lynparza is being jointly developed and commercialised by AstraZeneca and MSD.

The results of Study 08, a randomised, double-blinded, multi-centre Phase II trial, comparing Lynparza in combination with abiraterone (n=71) to abiraterone monotherapy (n=71) in patients with previously-treated mCRPC, regardless of homologous recombination repair (HRR) mutation status, were presented at the 2018 American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Annual Meeting in Chicago, US, 1-5 June 2018 as a "Best of ASCO (Free ASCO Whitepaper) presentation" and were published online today in the Lancet Oncology. The primary endpoint was rPFS. Secondary endpoints included time to second progression or death (PFS2), overall survival (OS) and health-related quality of life.

Noel Clarke, Professor of Urological Oncology, Christie NHS Foundation Trust, Manchester, UK, said: "This is the first time we have seen an improvement with the use of a PARP inhibitor in combination with abiraterone in patients with metastatic castration-resistant prostate cancer and this effect may be independent of HRR status. The data suggest this therapeutic combination may be a promising new treatment approach for this aggressive disease."

Sean Bohen, Executive Vice President, Global Medicines Development and Chief Medical Officer at AstraZeneca, said: "A previous trial demonstrated improvements in response rates with Lynparza monotherapy in metastatic castration-resistant patients with HRR mutations. The Study 08 combination data suggests that regardless of their mutation status, men with metastatic castration-resistant prostate cancer may potentially benefit from Lynparza in combination with abiraterone."

Roy Baynes, Senior Vice President and Head of Global Clinical Development, Chief Medical Officer, MSD Research Laboratories, said: "There is a significant unmet medical need for patients with metastatic castration-resistant prostate cancer as they are a high-risk group with limited treatment options. Lynparza is the first PARP inhibitor to demonstrate activity in combination with standard-of-care treatment in prostate cancer. These data from Study 08 represent another important milestone in the clinical development of Lynparza."

Median rPFS was 13.8 months with Lynparza and abiraterone compared to 8.2 months with abiraterone alone (HR 0.65; 95% CI 0.44-0.97; p=0.034). Median PFS2 was 23.3 months vs 18.5 months (HR 0.79; 95% CI 0.51–1.21). Median OS was 22.7 months with combination treatment versus 20.9 months with abiraterone alone (HR 0.91; 95% CI 0.60–1.38). Pre-specified exploratory subgroup analyses demonstrated an rPFS improvement in patients, regardless of HRR status (see Table 1). Study 08 was not powered for subgroup analyses, PFS2 and OS.

The safety profile of Lynparza and abiraterone was generally manageable, with no detrimental effect on quality of life compared to abiraterone alone. Grade ≥3 adverse events (AEs), serious AEs and treatment discontinuations due to AEs were more frequent with combination treatment than abiraterone alone (54% and 28%; 34% and 18%; 30% and 10%, respectively). The most common grade ≥3 AEs in the combination arm were anaemia (21%), pneumonia (6%) and myocardial infarction (6%). Serious cardiovascular events occurred in seven patients in the combination group and one patient in the abiraterone group.

In addition to Study 08, other studies are underway to explore the potential of Lynparza as a monotherapy for HRR-mutated mCRPC, including PROfound, which is testing Lynparza monotherapy vs. enzalutamide or abiraterone in patients with previously-untreated mCRPC. Additional trials are planned to explore Lynparza in combination for the treatment of mCRPC regardless of HRR status. Lynparza was granted Breakthrough Therapy Designation by the US Food and Drug Administration in 2016 for the treatment of BRCA-mutated or ATM-gene-mutated mCRPC.

Lynparza is a first-in-class PARP inhibitor approved for advanced ovarian cancer and metastatic breast cancer and has been used in over 20,000 patients. Lynparza has the broadest and most-advanced clinical trial development programme and AstraZeneca and MSD are working together to deliver Lynparza as quickly as possible to more patients across multiple cancer types, including prostate and pancreatic cancers.

NOTES TO EDITORS
About Study 08

Study 08 was a global, randomised, double-blinded, multi-centre Phase II trial of 142 patients, assessing the efficacy and safety of Lynparza tablets (300mg twice daily) and abiraterone tablets (4 x 250mg once daily) (n=71) compared to matched placebo and abiraterone tablets (4 x 250mg once daily) (n=71) in patients with metastatic castration-resistant prostate cancer (mCRPC), regardless of HRR status. Prednisone/prednisolone (5mg BID) was administered to patients in both treatment arms.

Patients in Study 08 had previously received docetaxel for mCRPC. Prior to enrolment, patients had received no more than two lines of chemotherapy.

The primary endpoint was radiologic progression-free survival (rPFS) (time from randomisation to radiologic progression or death). rPFS is increasingly used in clinical trials of mCRPC as a clinically-meaningful endpoint focusing on the impact of treatment on the disease progression to areas where spread of prostate cancer is common, notably soft tissue and bone.

Secondary endpoints included time to second progression or death, overall survival and health-related quality of life.

About metastatic castration-resistant prostate cancer (mCRPC)

Prostate cancer is the second-most common cancer in men, with an estimated 1.6 million new cases diagnosed worldwide in 2015 and is associated with a significant mortality rate.[i] Development of prostate cancer is often driven by male sex hormones called androgens, including testosterone.[ii] mCRPC occurs when prostate cancer grows and spreads to other parts of the body despite the use of androgen-deprivation therapy to block the action of male sex hormones.ii Approximately 10-20% of men with advanced prostate cancer will develop CRPC within five years, and at least 84% of these will have metastases at the time of CRPC diagnosis.[iii] Of men with no metastases at CRPC diagnosis, 33% are likely to develop metastases within two years.iii Despite an increase in the number of available therapies for men with mCRPC, five-year survival is only 28%.iii

About Lynparza

Lynparza (olaparib) was the first-in-class PARP inhibitor and the first targeted treatment to potentially exploit DNA damage response (DDR) pathway deficiencies, such as BRCA mutations, to preferentially kill cancer cells. Specifically, in vitro studies have shown that Lynparza-induced cytotoxicity may involve inhibition of PARP-enzymatic activity and increased formation of PARP-DNA complexes, resulting in DNA damage and cancer cell death.

Lynparza, which has the broadest clinical development programme of any PARP inhibitor, is being tested in a range of DDR-deficient tumour types, and is the foundation of AstraZeneca’s industry-leading portfolio of potential new medicines targeting DDR mechanisms in cancer cells.
