Results from the pivotal Phase III PACIFIC trial showing statistically-significant and clinically-meaningful progression-free survival (PFS) benefit with Imfinzi (durvalumab) in patients with locally-advanced (Stage III), unresectable non-small cell lung cancer (NSCLC) following standard chemoradiation therapy, a clinical setting where there are currently no approved treatments (Press release, AstraZeneca, AUG 31, 2017, View Source [SID1234520360]).
Results of the Phase III FLAURA trial showing statistically-significant and clinically-meaningful PFS with Tagrisso (osimertinib) over current standard-of-care erlotinib or gefitinib as 1st-line treatments in previously-untreated patients with locally-advanced or metastatic epidermal growth factor receptor mutation-positive (EGFRm) NSCLC.
Jamie Freedman, Executive Vice President, Head of the Oncology Business Unit at AstraZeneca, said: "The superiority of 1st-line treatment with Tagrisso in the FLAURA trial and the potentially transformative Imfinzi data from the PACIFIC trial reinforce our significant contribution to advancing medicines for patients across multiple stages of lung cancer. We are also proud to share with the medical community our progress towards addressing the needs of patients with other types of difficult-to-treat tumours, including advanced ovarian, breast, and head and neck cancers."

Pushing the boundaries of lung cancer research

In addition to the two Presidential Symposia presentations, data being presented at ESMO (Free ESMO Whitepaper) demonstrate the breadth and depth of AstraZeneca’s commitment to advancing the treatment of lung cancer:

Overall survival data on Tagrisso from the Phase II AURA trials in patients with EGFR T790M mutation-positive advanced NSCLC (Abstract #1348P)
PFS data and central nervous system (CNS) responses to Tagrisso in patients with EGFR T790M NSCLC in the Asia Pacific region (AURA17) (Abstracts #1331P, 1353P and 1354P)
Established expertise in women’s cancers

Emerging data from studies of Lynparza, Faslodex, potential new medicines and combinations within women’s cancers will include:

Latest Phase III OlympiAD efficacy and health-related quality-of-life data for Lynparza vs. chemotherapy in patients with HER2-negative metastatic breast cancer and a germline BRCA mutation (Abstract #243PD and 290P)
Phase III SOLO-2 data for Lynparza maintenance therapy in patients with platinum-sensitive relapsed ovarian cancer (Abstract #932PD)
Sustained commitment in head and neck cancer

AstraZeneca is presenting additional evidence of the efficacy and safety of Imfinzi and the early potential of its combination strategy in head and neck cancer, including oral presentations on:

Preliminary data from the Phase II HAWK study of Imfinzi in recurrent/metastatic head and neck squamous cell carcinoma (HNSCC) (Abstract #1042O)
Safety, tolerability and anti-tumour activity in the Phase Ib/II SCORES study of Imfinzi in combination with STAT3 inhibitor AZD9150 or CXCR2 inhibitor AZD5069, in patients with HNSCC (Abstract #1049PD)

MacroGenics Announces Termination of Duvortuxizumab Collaboration and License Agreement with Janssen

On August 31, 2017 MacroGenics, Inc. (NASDAQ: MGNX), a clinical-stage biopharmaceutical company focused on discovering and developing innovative monoclonal antibody-based therapeutics for the treatment of cancer, as well as autoimmune disorders and infectious diseases, reported that it had been notified by its partner, Janssen Biotech, Inc., that Janssen is terminating the collaboration and license agreement with MacroGenics relating to duvortuxizumab, a CD19 x CD3 DART molecule (Press release, MacroGenics, AUG 31, 2017, View Source [SID1234520350]). Enrollment of the Phase 1 dose-escalation study of this molecule is being discontinued.

Janssen reaffirmed its commitment to MGD015, also known as JNJ-9383, a second DART molecule licensed from MacroGenics. MGD015 is a preclinical program that targets CD3 and a non-disclosed cancer antigen expressed in hematological malignancies and lung cancer. Janssen has indicated that it anticipates initiating a first-in-human study with this molecule in 2018.

In the Phase 1 dose-escalation study of duvortuxizumab, multiple objective responses were observed in patients treated at various dosing levels tested. However, a number of patients experienced treatment-related neurotoxicity similar to that seen in patients treated with other CD19-targeted T-cell therapies. Given the recent advances in the highly competitive field for the treatment of B cell malignancies, the opportunity for development and commercialization has become less attractive.

"While this decision is disappointing, MacroGenics and its strategic partner, Janssen, continue to be fully committed to the DART platform and our ongoing collaboration on MGD015. Duvortuxizumab’s neurotoxicity profile is a CD19-targeting issue and has not been observed in our other DART clinical programs," said Scott Koenig, M.D., Ph.D., President and Chief Executive Officer of MacroGenics. "Given our large portfolio of product candidates currently being pursued, it is unlikely that we will continue development of this molecule at this time."

BeiGene Announces Closing of Global Strategic Oncology Collaboration with Celgene Corporation

On August 31, 2017 BeiGene, Ltd. (NASDAQ:BGNE), a clinical-stage biopharmaceutical company developing innovative molecularly targeted and immuno-oncology drugs for the treatment of cancer, reported the closing of its global strategic oncology collaboration with Celgene Corporation (Press release, BeiGene, AUG 31, 2017, View Source [SID1234520354]).

The collaboration was announced on July 5, 2017. Under the terms of the agreements, BeiGene has acquired Celgene’s commercial operations in China and assumed commercial responsibility for Celgene’s approved therapies in China (Abraxane, Revlimid, and Vidaza) and pipeline agent CC-122. Celgene has received exclusive rights to develop and commercialize BeiGene’s investigational anti-PD1 antibody, BGB-A317, for solid tumors in the United States, Europe, Japan, and the rest of the world outside of Asia. BeiGene retains rights to BGB-A317 for solid tumors in Asia (excluding Japan), and for hematological malignancies and internal BeiGene combinations globally. BeiGene will receive an aggregate of $413 million from Celgene in upfront licensing fees and equity investment, and will be eligible for up to an additional $980 million in development, regulatory, and sales milestones, as well as royalties on future sales of BGB-A317.

About BGB-A317

BGB-A317 is an investigational humanized monoclonal antibody that belongs to a class of immuno-oncology agents known as immune checkpoint inhibitors. It is designed to bind to PD-1, a cell surface receptor that plays an important role in downregulating the immune system by preventing the activation of T-cells. BGB-A317 has high affinity and specificity for PD-1. It is differentiated from the currently approved PD-1 antibodies in an engineered Fc region, which is believed to minimize potentially negative interactions with other immune cells. BGB-A317 is being developed as a monotherapy and in combination with other therapies for the treatment of a broad array of both solid tumor and hematologic cancers. BeiGene and Celgene have a global strategic collaboration for BGB-A317 for solid tumors.

Aptevo Therapeutics and MorphoSys End Joint Development and Commercialization Agreement for MOR209/ES414

On August 31, 2017 Aptevo Therapeutics Inc. (Nasdaq:APVO), a biotechnology company focused on developing novel immuno-oncology and hematology therapeutics, reported the end of its partnership with MorphoSys AG for the joint worldwide development and commercialization of MOR209/ES414, a targeted immunotherapeutic for the treatment of metastatic castration resistant prostate cancer (mCRPC) (Press release, Aptevo Therapeutics, AUG 31, 2017, View Source [SID1234520353]). Aptevo will regain worldwide development and commercialization rights for MOR209/ES414 (now known as APVO414) and intends to continue to advance APVO414 through the completion of Stage 1 of an ongoing Phase 1 continuous infusion, dose-escalation clinical study evaluating the safety, tolerability and clinical activity of escalating doses of APVO414 in patients with mCRPC.

"We’re encouraged by the latest preliminary data from the ongoing Phase 1 clinical study of APVO414," said Dr. Scott Stromatt, Senior Vice President and Chief Medical Officer at Aptevo. "The data suggest that administration of APVO414 by continuous infusion, rather than weekly intravenous (IV) dosing, is effective at reducing the titer of anti-drug antibodies (ADA) previously observed in the initial weekly IV dosing cohorts."

In the initial cohorts of the Phase 1 dose escalation study, twelve patients with mCRPC were treated with weekly intravenous infusions of APVO414. Seven of these patients (58%) developed ADA with very high titers (as high as 1:250,000). None of the patients had any adverse reactions due to the ADA, but patients with high ADA titers cleared the drug from their blood to undetectable levels.

The amended protocol utilizes continuous intravenous infusion and two cohorts of patients have completed dosing without any dose limiting toxicities. Three of six patients (50%) developed ADA but with markedly lower titers of ADA (1:160 or 1:320). Additionally, drug was detected in the serum of all patients.

"These results clearly demonstrate that the administration regimen markedly reduced the generation of ADA. Additionally, we have seen early pharmacodynamic effects of the drug such as redistribution of T cells. We are encouraged and plan to continue dose escalation in order to determine the maximum tolerated dose and to examine the clinical activity of APVO414," said Dr. Stromatt.

APVO414 is a first-generation bispecific antibody candidate, developed using Aptevo’s ADAPTIR protein therapeutic platform. APVO414 is engineered to simultaneously target PSMA on prostate cancer cells, and CD3 on T-cells, and functions by redirecting cytotoxic T cell activity towards PSMA-expressing tumor cells.

Promising preclinical data demonstrating the ability of APVO414 to induce target-dependent tumor cell killing as well as target-dependent T cell proliferation were previously presented at the American Association for Cancer Research (AACR) (Free AACR Whitepaper) Annual Meeting and recently published in the Journal of Molecular and Cellular Biology (2016 Mol Cancer Ther; 15(9); 2155–65). In addition, APVO414 demonstrated lower levels of T cell dependent cytokines compared to other bispecific formats, which, if confirmed in clinical studies, could offer the potential for enhanced safety and tolerability compared to other immuno-oncology bispecific antibody approaches.

"Aptevo has made a number of significant improvements to our ADAPTIR platform since the development of our first-generation bispecific candidates, like APVO414," commented Jane Gross, Ph.D., Senior Vice President and Chief Scientific Officer. "Our next generation ADAPTIR technology platform has been optimized to enable the development of bispecific antibody candidates with highly-desirable drug-like properties, including, enhanced potency and stability, prolonged half-life, and excellent manufacturing attributes – similar to traditional antibodies. Importantly, we have utilized state-of-the-art technologies to examine our next generation bispecific candidates and believe that we identified and eliminated the root cause of the ADA seen with APVO414. We look forward to obtaining additional information from the ongoing APVO414 clinical trial and advancing next generation ADAPTIR bispecific molecules into clinical development."

About Prostate Cancer

Although screening, radiation, surgery and hormone ablation therapy have greatly improved the detection and treatment of early-stage prostate cancer, the relapse rate following initial anti-androgen therapy remains high, and there remains a significant unmet medical need for patients with metastatic castration resistant prostate cancer for whom current therapies have demonstrated only a limited increase in overall survival. The global market for CRPC therapeutics is expected to reach $9.5 billion by 2020

About the ADAPTIR Pipeline

Two first generation ADAPTIR molecules are currently in clinical development: APVO414, which is being investigated in a Phase 1, dose escalation, continuous infusion study to evaluate safety and tolerability in patients with metastatic castration resistant prostate cancer; and, otlertuzumab, a monospecific antibody targeting CD37 under investigation for the treatment of chronic lymphocytic leukemia. In addition, Aptevo has several ADAPTIR candidates in preclinical development, including: APVO436, an optimized, next generation bispecific antibody candidate designed to simultaneously target CD123 and CD3 and redirect T cell cytotoxicity for the treatment of acute myelogenous leukemia (AML), a form of blood and bone marrow cancer; ALG.APV-526, a bispecific antibody candidate, partnered with Alligator Bioscience, featuring a novel mechanism of action designed to simultaneously target 4-1BB (CD137) and an undisclosed tumor antigen, and, APVO210 – a bispecific ADAPTIR candidate with a novel mechanism of action based on cytokine delivery currently in preclinical development for autoimmune and inflammatory diseases.

Iovance Biotherapeutics Announces FDA Fast Track Designation for LN-144 for Treatment of Advanced Melanoma

"We are pleased that the FDA has granted Fast Track designation to LN-144 for the treatment of advanced melanoma. The Fast Track designation underscores that advanced melanoma remains a serious condition and that LN-144 may have the potential to address this unmet medical need," said Dr. Maria Fardis, PhD, MBA, Chief Executive Officer of Iovance Biotherapeutics. "We look forward to a closer interaction with the FDA as we advance the clinical development of LN-144 for the treatment of advanced melanoma."

C-144-01 is a Phase 2 study evaluating LN-144, Iovance’s lead product, for treatment of patients with metastatic melanoma. The study is currently enrolling and is expected to enroll up to 60 patients in two cohorts: Cohort 1 allows for non-cryopreserved TIL product to be administered to patients, while Cohort 2 involves administration of a cryopreserved product. In June 2017, the Company presented a poster at the 2017 American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Annual Meeting with data from 16 patients enrolled in the first cohort of this study. The data reported showed clinically-meaningful outcomes in the evaluable patients, with a 29% Objective Response Rate (per RECIST v1.1) including one complete response continuing beyond 15 months post-administration of a single TIL treatment, and 77% of patients had reduction in target tumor size. The Phase 2 study was conducted in a heavily pre-treated patient group, all of which had received prior anti-PD-1 therapy and 88% with prior anti-CTLA-4 checkpoint inhibitors, with a median of three prior therapies.

The FDA’s Fast Track process is designed to facilitate the development, and expedite the review of drugs that treat serious conditions and fill an unmet medical need. Fast Track designation allows more frequent meetings and communications with the FDA to discuss the drug’s development plans and review process. The Fast Track designation also allows for a rolling review of a company’s Biologic License Application (BLA).
