New hope for bowel cancer patients as fresh partnership between Carina Biotech and CellVec enables advancement of clinical trials. – Bio-IT World

SINGAPORE, 10 November 2021 Singapore-based viral vector CDMO CellVec announces today that it has been selected as the manufacturer of choice for Australian cell therapy immuno-oncology company Carina Biotech, undertaking the production of GMP-compliant lentivirus constructs for its LGR5 CAR-T. The partnership is slated to advance clinical trials for a treatment designed for patients with advanced colorectal (bowel) cancer.

CellVec is a certified GMP gene therapy contract development and manufacturing organisation that provides an advanced lentiviral vector platform to upscale production of viral vectors and develop novel gene transfer technologies to advance therapies to clinical application. Its strategic offering of bespoke manufacturing services will enable the clinical grade lentivirus to be produced under GMP standards while using Carinas proprietary manufacturing process, progressing the production of LGR5 CAR-T cells for a first in-human clinical trial in H2 2022.

The partnership with Carina Biotech marks a significant milestone for us to facilitate the furtherance of gene therapies. It attests to our capabilities to effectively scale bespoke viral vector manufacturing processes, enabling the advancement of different clinical therapies from bench to bedside that will benefit more patients across the world. We look forward to supporting Carina in the successful development of its LGR5 CAR-T cells, said Dr Ang Peng Tiam, Chairman of CellVec and Medical Director of Parkway Cancer Centre, the largest private oncology service provider in the region.

We are delighted to be working with CellVec because of their outstanding track record and expertise, said Professor Simon Barry, VP of CAR-T Manufacturing Research and Development and the co-inventor of Carinas lead CAR-T cell. Their flexibility and willingness to incorporate Carinas proprietary manufacturing process was an important consideration in the selection of CellVec as our service provider.

Leveraging its advanced CellVec Vector Platform, CellVecs efficacious manufacturing processes will scale the production of high-titre, high yield lentivirus constructs in an accelerated timeline (6 to 8 months) for the project. The LGR5 CAR-T cell targets the LGR5 cancer stem cell marker that is highly expressed on advanced colorectal cancer and some other cancers, resulting in durable tumour suppression and the prevention of relapses commonly seen in patients with colorectal cancer.

We are continuing to see fantastic results with our LGR5 CAR-T cell in pre-clinical testing. Colorectal cancer is Australias second deadliest cancer and its incidence is rising in people under the age of 50 with many of these people being diagnosed with advanced disease and a very poor prognosis, said Dr Deborah Rathjen, CEO of Carina Biotech.

After our recent successful capital raise and welcoming new impact investors to our company, we are on track for a pre-IND submission in Q2 of 2022 and an IND submission to the FDA in the second half of 2022 and the initiation of a Phase I/II clinical trial in patients with advanced colorectal cancer.

Commenting on the potential of the partnership, Dr Gayatri Sharma, Chief Commercial Officer of CellVec said, Carinas work in LGR5 CAR-T therapy aligns strongly with our mission of innovating for patient benefit. Our manufacture of the required lentivirus constructs will accelerate the clinical application and adoption of the therapy, bringing it to more patients around the world and ultimately reduce the incidence and mortality of colorectal cancer. We are pleased to be part of this journey with Carina and are extremely excited for what this will bring to the colorectal cancer community.

CellVec boasts a GMP-certified pharmaceutical quality system (PQS) and facility, awarded by the Health Sciences Authority of Singapore under current PIC/S guidance annexes for medicinal products. These are designed in alignment with US FDA, EU GMP and TGA (Australia) regulations and industry expectations. With a strategic location in Singapore, the regions biotech hub, CellVec is able to facilitate on-time delivery of quality viral vectors across the world, including to the US and the UK.

About Carina Biotech

Adelaide-based Carina Biotech is developing CAR-T and other adoptive cell therapies for the treatment of solid cancers. As well as its LGR5-targeted CAR-T cell for advanced colorectal cancer, Carina has a deep pipeline of CAR-T programs.

Using its proprietary chemokine receptor platform, Carina aims to improve access to and infiltration of solid cancers by CAR-containing cells resulting in more potent and specific cancer killing and reduced off-target effects in a number of cancers.

Carina also has a fully integrated, proprietary manufacturing process that has both reduced manufacturing time and improved CAR-T cell quality, capable of delivering robust serial-killing CAR-T cells to patients.

About LGR5

LGR5 is acancer stem cell markerthat is highly expressed on advanced colorectal cancer and some other cancers. In colorectal cancer patients,LGR5+ expression has been correlated with a particularly poor prognosis.

Cancer stem cells are a small sub-population of cells within a tumour with the ability to self-renew, differentiateinto the many cell types of a tumour, initiatenew tumours, and resistchemotherapy and radiotherapy (leading to relapses).

By targeting cancer stem cells, it is hoped that this therapy will reduce the tumours ability to generate new cancer cells, resulting in durable tumour suppression and preventing the relapses that are very common in patients with colorectal cancer.

Carinas pre-clinical studies of the LGR5-targeted CAR-T cell have shown highly promising results with complete tumour regression and no tumour recurrence. They have also demonstrated impressive tumour access and prolonged CAR-T cell survival.
