ASLAN will grant BioGenetics exclusive rights to commercialise varlitinib in South Korea in exchange for an upfront payment of US$2 million and up to US$11 million in sales and development milestones. ASLAN is also eligible to receive tiered double digit royalties on net sales up to the mid-twenties. ASLAN will continue to fund all clinical development of varlitinib, BioGenetics will be responsible for obtaining initial and all subsequent regulatory approvals of varlitinib in South Korea.

ASLAN is currently conducting a global pivotal trial (TreeTopp) in second-line biliary tract cancer (BTC), with topline data expected in the second half of 2019. At the recent ASCO (Free ASCO Whitepaper) GI conference, ASLAN presented positive data from an ongoing multicentre phase 1b/2 clinical trial of varlitinib plus gemcitabine and cisplatin in first-line BTC. Varlitinib has been awarded orphan drug designation for the treatment of BTC by the Ministry of Food and Drug Safety in South Korea, which provides certain benefits for the development and commercialisation of varlitinib in South Korea including an extension of the marketing exclusivity period and exemption of certain local clinical trial requirements.

Dr Carl Firth, Chief Executive Officer of ASLAN Pharmaceuticals, commented: "We are delighted to partner with a team that brings strong knowledge of the South Korean regulatory and commercial environment. We believe BioGenetics is well placed to maximise the value of varlitinib in BTC and potentially other tumour types in the future."

JooHoon Ahn, Chief Executive Officer of Biopharma, BioGenetics, commented: "We are excited by the clinical data in BTC that ASLAN has generated to date. The unmet need for effective treatments for BTC, one of the ten most prevalent cancers in South Korea, is high. Our partnership with ASLAN is in-line with our strategy to identify high-quality, late stage development assets that have the potential to transform treatment paradigms and address pressing needs in oncology. We have attracted a team of experienced pharmaceutical executives to build our pharmaceutical division and we look forward to working closely with ASLAN to realise the potential of varlitinib in South Korea."

In 2015, ASLAN entered a collaboration and license agreement with Hyundai Pharm to develop and commercialise varlitinib for the treatment of cholangiocarcinoma (CCA) in South Korea. Prior to executing a broader agreement with BioGenetics, ASLAN exercised its right to buy back the rights to varlitinib in CCA, making a payment of $0.3M to Hyundai Pharm.

"A series of significant achievements in 2018 have positioned Acceleron to execute on a number of key milestones across the entire pipeline during 2019 and 2020," said Habib Dable, President and Chief Executive Officer of Acceleron. "First and foremost, we and our global collaboration partner, Celgene, plan to submit marketing applications in the U.S. and E.U. for our lead product candidate, luspatercept, in lower-risk myelodysplastic syndromes and transfusion-dependent beta-thalassemia in the first half of the year. At the same time, we’re continuing to evaluate luspatercept’s potential to treat a range of anemias, from first-line therapy in MDS via the ongoing COMMANDS Phase 3 trial, to non-transfusion-dependent beta-thalassemia, myelofibrosis and beyond."

"In addition, our wholly-owned programs in neuromuscular and pulmonary disease are all advancing. We’re anticipating topline results from the placebo controlled part of our Phase 2 trials evaluating our locally-acting muscle agent, ACE-083, in FSHD and CMT by the end of the year. Lastly, 2020 will bring important Phase 2 trial results in PAH with sotatercept, which we believe has the potential to alter the treatment landscape for this devastating disease."

Development Program Highlights

Hematology

Luspatercept: Myelodysplastic Syndromes (MDS), Beta-Thalassemia, and Myelofibrosis (MF)
Luspatercept is an investigational first-in-class erythroid maturation agent (EMA) designed to address a late-stage erythroid maturation defect that results in chronic anemia and the need for regular red blood cell transfusions in adults with serious hematologic diseases. Luspatercept is part of the global collaboration between Acceleron and Celgene.


The MEDALIST and BELIEVE Phase 3 trial results in patients with lower-risk MDS and transfusion-dependent beta-thalassemia, respectively, were presented at the 60th ASH (Free ASH Whitepaper) Annual Meeting and Exposition in December 2018.


The MEDALIST and BELIEVE presentations were both selected for presentation during the "Best of ASH (Free ASH Whitepaper)" session at the meeting.


Acceleron and Celgene plan to submit a Biologics License Application (BLA) to the U.S. Food and Drug Administration (FDA) for luspatercept in patients with anemia related lower-risk MDS and beta-thalassemia in April 2019.


Acceleron and Celgene remain on track to submit a Marketing Authorization Application (MAA) to the European Medicines Agency (EMA) for luspatercept in patients with anemia related to lower-risk MDS and beta-thalassemia in the first half of 2019.

"2018 was a year of strong delivery across the portfolio with record numbers of patients treated in our clinical trials. We moved through the dose escalation portion of our studies with ADP-A2M4 and ADP-A2M10 and we are now treating patients in the expansion phases for both programs. Our third program, ADP-A2AFP, moved to the second dose cohort at target doses of 1 billion cells. We are very pleased to have observed an acceptable safety profile, thus far, with all three programs, showing no evidence of off-target toxicity or alloreactivity," said James Noble, Chief Executive Officer. "We are now able to devote our resources to these programs following the successful transition of NY-ESO to GSK."

"We made equally impressive progress in manufacturing with our in-house facility going from our first ever dose, at the beginning of 2018, to being able to produce target doses for up to 10 patients per month. In the UK, we started up our vector manufacturing that should begin to produce vector later this year. 2019 promises to be a significant year, with data emerging across our portfolio from May onwards. We look forward to reporting clinical data throughout the year," added James Noble.

Clinical momentum

Initial safety testing is complete in the triple tumor and non-small cell lung cancer (NSCLC) studies with ADP-A2M10, as well as the basket study with ADP-A2M4. All three studies are enrolling and treating patients with up to 10 billion cells in the expansion phases with no pre-determined stagger between dosing required.

In 2018, the Safety Review Committee (SRC) endorsed dose escalation through Cohorts 1, 2, and 3 of these studies, after reviewing safety data from 16 patients treated in the ADP-A2M10 studies and nine patients in the ADP-A2M4 study.

In the hepatocellular carcinoma study with ADP-A2AFP, the SRC endorsed escalation to safety Cohort 2 to treat patients with a target dose of 1 billion cells.

To date, across all four studies, most adverse events have been consistent with those typically experienced by cancer patients undergoing cytotoxic chemotherapy or other cancer immunotherapies with no evidence of alloreactivity or toxicity related to off-target binding.

Building an integrated company

Since the opening of the Navy Yard facility in January 2018, Adaptimmune can now manufacture cells for up to 10 patients per month, and this is scalable to 100 patients per month without significant capital expenditure. Further, an additional 10 patients per month can be treated with cells produced at a third-party vendor HCATs. Both the Navy Yard and HCATs facilities are now able to routinely produce cells to meet target doses across a broad range of solid tumors. This capacity will allow Adaptimmune to service its existing and planned clinical trials.

With respect to vector, Adaptimmune is well supplied as its own vector manufacturing has completed its first engineering run with first production anticipated in 2019, as well as production in place at a third-party vendor. The vendor has already produced vector for ADP-A2M10, ADP-A2M4, ADP-A2AFP, and next generation SPEAR T-cells.

In light of the Company’s increased clinical focus, Rafael Amado assumed the new role of President of R&D last year to bring the clinical and research functions under a single leadership, facilitating alignment and integration of all parts of the R&D structure.

The Company is working with more than 20 active clinical trial sites at leading cancer centers in the US, Canada, and the EU. In Europe, the infrastructure has been tested and has delivered the first doses to patients with additional patients being enrolled in the UK and Spain. Adaptimmune has also reached agreement on an expanded collaboration with MD Anderson Cancer Center (Houston, TX) to further enhance the Company’s translational research capabilities.

While progressing studies with ADP-A2M10, ADP-A2M4, and ADP-A2AFP as well as planning for the next stage of clinical development, including potential registration trials, Adaptimmune continues to progress developing next generation SPEAR T-cells, new targets, other HLAs, and an off-the-shelf product.

Finally, Adaptimmune is funded through to late 2020, based on management’s current estimates, with Total Liquidity(1) of $205 million (including cash and cash equivalents of $68 million) at year-end 2018.

"Atara has established a leading next-generation CAR T portfolio," said Dietmar Berger, M.D., Ph.D., Global Head of Research and Development of Atara Biotherapeutics. "Encouraging pre-clinical results at AACR (Free AACR Whitepaper) show the potential of our EBV-specific T cell platform to generate off-the-shelf, allogeneic CAR T immunotherapies. We also look forward to our MSK collaborators’ clinical results of a mesothelin-targeted autologous CAR T for patients with advanced malignant pleural disease."

Mesothelin is a solid tumor-associated antigen that is expressed at high levels on the surface of cells in aggressive solid tumors including mesothelioma, triple-negative breast cancer, ovarian cancer, pancreatic cancer and non-small cell lung cancer. Initial results from an ongoing MSK investigator-sponsored Phase 1 study (NCT02414269) of a mesothelin-targeted CAR T immunotherapy for patients with malignant pleural cancers were presented at the 2018 American Society of Gene and Cell Therapy (ASGCT) (Free ASGCT Whitepaper) Annual Meeting and support activity and safety in patients with advanced mesothelioma1,2. This ongoing Phase 1 dose-escalation study continues to accrue patients and the initial results at ASGCT (Free ASGCT Whitepaper) 2018 showed enhanced response rates when patients were subsequently treated with pembrolizumab, a PD-1 checkpoint inhibitor. MSK is also investigating mesothelin-targeted CAR T cells for patients with advanced breast and lung cancer (NCT02792114).

In January 2019, Atara announced an exclusive license and collaboration agreement with MSK to develop a next-generation, mesothelin-targeted CAR T using novel 1XX CAR signaling domain and PD-1 dominant negative receptor (DNR) checkpoint inhibition technologies for patients with mesothelin-associated solid tumors.

Abstract 2310: Functional demonstration of CD19 chimeric antigen receptor (CAR) engineered Epstein-Barr virus (EBV) specific T cells: An off-the-shelf, allogeneic CAR T-cell immunotherapy platform
Session Category: Immunology
Session Title: Adoptive Cell Therapy 2
Poster Presentation Date and Time: Monday, April 1, 2019 from 1:00 pm – 5:00 pm EDT
Location: Georgia World Congress Center, Exhibit Hall B
Authors: Blake T. Aftab, Rhine R. Shen, Christina D. Pham, Michelle Wu, Daniel J. Munson
Affiliations: Atara Biotherapeutics
Summary: Atara engineered EBV-specific T cells to express second-generation CD19 CARs, utilizing CD28 or 4-1BB co-stimulatory domains, resulting in high expression of both CD19 CAR and EBV T cell receptor (TCR). The chimeric EBV.CD19.CAR T cells exert potent and specific cytotoxicity against CD19-positive cells but have limited activity against CD19-negative cells. These findings establish feasibility for engineering EBV-specific T cells by leveraging next-generation CAR technologies, and support further development as an off-the-shelf, allogeneic CAR T immunotherapy platform.
