Clinical Trials & QA Services

We are a pharmaceutical consulting company and a registered CRO that conducts Clinical Trials from initiation to closure and helps organizations set effective QMS.

A quick list of services we offer:

Your toolset for increasing growth

Outsourcing is an excellent way to access resources and expertise quickly without capital investment or long-term commitment. 

Using the services of a contractor, you will be able to deal with the peaks and troughs of product development and focus on your ‘core business’.

We can help your organisation make better – informed decisions and understand the risk profile from a regulatory and quality perspective.

We provide business solutions for


Non-compliance has a profound effect on cost, reputation and the lives of your company customers or patients.


Newer business models are evolving as CROs (Contract Research Organisation) are increasingly entering strategic partnerships and alliances.


Pharmaceutical distributors play an important role to assure the quality of medicines along the supply chain.

We’re changing the way pharmaceutical organisations work by helping them improve their QMS with our QA outsourcing services.

1. Minimize the number of full-time staff

In other words, it is actually economical than having one of your own members of staff performing QA tasks.
For example, performing an audit takes much more time and effort than just being on site. During these activities, your valuable staff will not be able to tackle their regular tasks, which could create a backlog and increase work-related stress.

2. QA tasks will be conducted in a timely manner

It is cost-effective to hire professional QA staff because of their ability to perform QA-related tasks much faster than people who are performing it as an additional work task due to reasons such as experience and the frequency in which they perform them.

3. Flexibility: Resources when you need them

When you hire additional staff for audits, you run the risk of not having sufficient work for them later on. By outsourcing these needs, you ensure a flexible and cost-effective approach without wasting resources. This way, you have your needs fulfilled when you want it and how you want it.

4. Consistency:
Up to date with regulatory compliance

The growing number of regulations and the frequency with which they are updated means that you have to invest a lot of time and effort in monitoring and evaluation. We provide a full- service “one-stop” solution for developing, implementing, assessing and optimising your QMS.

5. More objectiveness

We are very aware of the pressures that can be experienced within organizations regarding obtaining ‘favorable’ audit outcomes. As there is no working relationship between an auditor and the departments mentioned above, there is no direct or indirect pressure.
