FREQUENTLY ASKED QUESTIONS

How is payment facilitated, and is there a satisfaction guarantee?

An invoice will be sent to the Coordinating Center at the time of trial activation; payment is due within 30 days of issue. However, we provide a 90-day, money-back guarantee. If we receive an email message from the Coordinating Center within 90 days of the trial’s activation requesting its deactivation, a full refund will be given within 30 days.

Can Randomize.net accommodate blinded randomization?

Yes. Please see Doubled-Blinded Trials for more information.

Can someone at Randomize.net create the randomization application for us?

Yes. For no additional cost, Randomize.net can create the randomization application to meet your specifications.

Is there any cost for registering as a Coordinating Center?

No. There is no cost for registering as a Coordinating Center or for a randomization application. Costs are incurred only when the application is activated.

What sort of back-up system do you have?

Our website is hosted by a very secure and reliable server and the database is backed up continuously.

How is security facilitated?

Our secure socket layer (SSL) software is the industry standard and among the best software available today for secure commerce transactions. It encrypts all information and subject data, so that it cannot be read as the information travels over the internet.

Does Randomize.net provide accrual reports?

Yes. We currently provide three types of accrual reports: monthly by clinical site; by stratification variables; and, a treatment allocation list.

We have randomized a subject using the wrong subject ID number. How do we change the subject ID?

Have the Coordinating Center contact us at info@randomize.net and we will change subject ID number.

How are subject ID numbers assigned?

When randomizing a subject the clinical site must provide a subject ID number. No two subjects in the trial can have the same ID number. The best way to assign subject ID numbers is for each clinical site to maintain a registration log into which information about each subject is entered for clinical site use only. The information entered can vary depending on the trial. Typically, the information includes subject's name, date of randomization and the stratification variables. A pre-filled field in the registration log assigns the ID.

Can email confirmations be sent to more than one recipient?

Yes. You can configure multiple email addresses for each clinical site, so that whenever a particular clinical site randomizes a subject, a confirmation is sent to each address. In addition, you can configure multiple email addresses to receive a confirmation for every randomization, regardless of clinical site.

How does randomization work?

See Randomization Algorithms for information on how randomization works.
