Stelis BioSource

Contract Development Manufacturing Organisation for Biopharmaceuticals

Quick Contact Stelis BioSource


Stelis BioSource

Stelis BioSource® is an outsourcing partner for process development, current good manufacturing practice (cGMP) production and aseptic filling of biopharmaceutical products.

The company is the contract development manufacturing organisation (CDMO) division of Stelis Biopharma, a pure-play, independent biopharmaceutical company.

With its end-to-end capabilities, Stelis handles development stages ranging from pre-clinical to commercial for recombinant proteins expressed in both microbial and mammalian systems.

Research and development services for biopharmaceutical development

Set up in 2014 with 22,000ft2 of lab space, Stelis BioSource’s modern research and development (R&D) facility in Bangalore offers a wide range of capabilities and employs scientists with the competency and experience necessary to develop biopharmaceuticals to regulated market standards.

The facility is designed to handle up to Biosafety Level 2 (BSL-2) organisms and is certified to meet the International Standardisation Organisation (ISO) 9001:2008.

The cell line and process development in microbial and mammalian systems is supported by extensive physicochemical and bio-analytical characterisation capabilities. Other services include scale-up and process optimisation to ensure seamless transfer of process to commercial-scale manufacturing. The company’s early stage development offerings include cell banking and characterisation.

Process development and scale-up services

Stelis BioSource has invested in high-performance technologies that support robust and efficient processes for both microbial and mammalian systems.

The company’s upstream process development services include production clone finalisation and media screening; the optimisation of bioprocesses to establish high yields of target proteins, expressing proteins as inclusion bodies, periplasmic, secreted or soluble in microbial expression system; mammalian process scale-up in 100% disposable systems with batch, fed-batch and perfusion modes of production; and establishing critical and key quality attributes.

Stelis BioSource’s downstream / purification process development services include establishing high-recovery purification processes of complex proteins; development of filtration processes such as ultrafiltration, diafiltration and hollow fibre filtration; and providing depth and crossflow modes, generating final drug substances (DS) in both liquid and lyophilised formats.

The company’s scale-up and tech-transfer services include optimising bioprocesses based on quality-by-design (QbD) principles, developing process analysis technology (PAT) for both mammalian and microbial processes, performing efficient tech-transfer to either customers’ or Stelis BioSource’s manufacturing facilities, and providing process characterisation studies using scale-down models.

Formulation development services for injectables

Stelis BioSource is experienced in developing injectable formulations in vials, prefilled syringes and cartridges.

Its capabilities include excipient screening and pre-formulation studies, stability studies at different temperature conditions meeting International Conference of Harmonisation (ICH) guidelines, and analytical characterisation of formulations, as well as comparison studies and stability analysis.

cGMP manufacturing services

Stelis BioSource’s state-of-art, 200,000 ft2, commercial-scale bio-manufacturing facility in Bangalore has the capability to produce simple and complex recombinant biotherapeutics from both microbial and mammalian cell culture systems.

The facilities are designed to meet industry guidelines worldwide, including the US Food and Drug Administration (FDA), the European Medicines Agency (EMA) and the World Health Organisation (WHO).

The microbial production suite follows a hybrid model with conventional SS fermenters (Sartorius) in the Upstream and with both single-use and conventional systems in the downstream. The upstream capacities are 50l, 300l and 1,000l.

For mammalian cell culture manufacturing, Stelis adopts the latest single-use technology of Merck-Millipore for both upstream and downstream operations. This allows greater production flexibility and reduces the likelihood of cross-contamination, thereby improving compliance and facilitating quick changeovers. Starting with two bioreactor train line-ups from 50l, 200l and 2,000l, plans are in place to add two more lines.

In addition, the facility is capable of handling batch, fed-batch and perfusion fermentation with pre and post viral segregation single-use flow path chromatography system (Merck Millipore), as well as viral-filtration, ultra-filtration and diafiltration.

Aseptic fill / finish services

Stelis BioSource develops DS and active ingredients into stable formulations and fill / finish injectable formats. The company’s high-end filling lines are integrated with isolators to meet clinical and commercial requirements.

The pre-filled syringe and cartridge lines are both from Bausch & Strobel with integrated Steriline isolators and individual capacities of ten million and 20 million per annum, respectively, on a single-shift basis.

The vial line is from Tofflon and features an integrated isolator and lyophiliser with a capacity of ten million per annum on a single-shift basis.

The packaging line comprises labelling and syringe assembling machines from Bausch & Strobel, and a blistering and cartoning line from IMA with capacities of 10 million cartons per annum on a single-shift basis.

Stelis BioSource also provides cold chain inventory management through dedicated warehouses at the facility.

Analytical development and validation services

Stelis BioSource’s analytical lab features state-of-the-art equipment offering high-end analytical tools and methods for the characterisation of complex biologics and CDMO services.

The division specialises in performing orthogonal analysis using spectroscopic and spectrometric methodologies, developed in compliance with ICH, FDA and EMA guidelines.

Stelis BioSource offers validation services, in-process release testing, stability analysis, bioassay development and in-process analytics.

Quality control and testing services

Stelis BioSource offers on-site cGMP analytical and microbiological testing services to support in-process and release requirements, as well as characterisation of reference and finished products to meet analytical comparability requirements.

The company’s testing capabilities include raw materials, consumables and packaging materials, in-process and release testing, analytical method qualification and validation using ICH and the US FDA guidelines, as well as complex bioassays such as cell-based immunological assays, protein characterisation, microbiological testing and stability testing as per ICH guidelines.
