Aseptic fill and finish of clinical trial material
PROXY provides aseptic fill and finish (F&F) of clinical trial material (CTM) on a small scale (handfilling), into different sizes of vials, bottles, syringes and plastic bags. This service includes master batch record documentation, 100% visual inspection and weight checks, as well as sterility, closure integrity and bacterial endotoxin tests.
As a related activity we offer the GDP-licensed storage and distribution of CTM for multi-centre clinical trial studies.
QC testing services – chemistry
PROXY provides a range of QC testing services in the field of chemistry, including testing of (bio)pharmaceutical raw materials (APIs and excipients), utilities (water and gas) and finished dosage forms, for release as well as stability samples. All tests are carried out according to pharmacopoeia (compendia) and/or customers' registration dossiers. Analytical test methods can be validated according to ICH guidelines.
QC testing services – microbiology
In the field of microbiology PROXY Laboratories' QC testing services include analysing for bioburden (TAMC, TYMC) and for the absence of specific microorganisms (e.g. E. coli, Salmonella). We use specialised methods such as the microbiological assay of antibiotics (turbidimetric and cylinder plate), the bacterial endotoxins test (turbidimetric, chromogenic, and gel-clot), and the preservative efficacy test.
Sterility tests are performed in our cleanroom. We can develop and validate microbiological test methods and identify microorganisms using MicroSEQ technology.
Analytical R&D for the life sciences industry
PROXY uses sophisticated equipment such as UPLC-QToF-MS and UPLC-TQ-MS for the development and validation of analytical methods to be used for analysing (bio)pharmaceuticals and samples of biological origin (plasma, urine and tissue).
One of our specialised areas is oligos; i.e. oligonucleotides, oligopeptides and oligosaccharides. PROXY also carries out molecular identification and characterisation as well as impurity profiling.
PROXY provides pivotal, ongoing (follow-up) and in-use stability studies according to ICH guidelines. Climate-controlled walk-in stability rooms conditioned at 2°C-8°C, 25H60 and 30H65 as well as cabinets at -80°C, -20°C, 2°C-8°C, 15°C, 40H75 and 30H75 (zone IVa) are in place and permanently monitored for temperature and humidity.
We offer products, processes, methods and cleaning procedures for validation studies, all carried out according to ICH guidelines.
PROXY Laboratories also provides specific tests, studies and services, including environmental monitoring, closure integrity testing, and residual solvents (HS-GC-FID/MS), as well as Qualified Person services such as batch release, QA-consultancy, CTM storage and supply.
