Blinding solutions

Faubel provides blinding for single and double-blind clinical trials.

Research companies in the pharmaceutical industry are often faced with the challenge of appropriately blinding the study medication in clinical trials so that the doctors, nursing staff, patients and data management personnel involved have no information about the treatment allocated to individual trial participants. This is the only way to eliminate undesirable influences in a clinical trial.

Avoiding influences

Often, it is not enough to simply cover up existing labels or surfaces. The product color, the glass or even impressions in the glass or plastic can allow conclusions to be drawn as to the contents. First-class blinding saves both time and costs – by avoiding elaborate color-matching between liquid placebo and active substance groups, for example.

Faubel has developed a variety of labeling solutions that can be used for blinding in single or double-blind clinical trials. These allow vials, bottles, boxes, tubes and blister packs to be fully covered, and also protect trial-specific data against tampering.

Blinding solutions

A Blinding Box made from opaque cardboard can make the circumference and height of a container, as well as the color of its contents, completely unrecognizable. The container is held stable in the center of the box. For single-blind trials where the staff involved in the trial are allowed to know how the products are allocated, blinding can take place after the opening is disinfected. For double-blind trials, disinfection can take place after blinding. In both cases, the hypodermic needle can be easily inserted into the container. An integrated control window allows the product to be identified in an emergency. Once opened for the first time, however, it becomes permanently visible. The Blinding Box can be processed quickly and easily by research companies without the use of tools.

Blinding for tubes and blister packs

Special single and multi-layer labels provide blinding for tubes and blister packs while allowing them to be labeled with the necessary dosage instructions. All blinding solutions can be supplemented with optional Braille printing, variable data, safety features such as tamper-evident or code-break functions, and documentation elements.
