Formed in early 2015, Callitas is a clinical-stage company developing technologies to treat obesity, for weight management, and for female health and wellbeing.
"As a company with its roots in female health and wellness, we are committed to delivering breakthrough products and services that truly improve daily living," said Gary Thompson, its president and chief executive.
"Aligning our logo with the beautiful and strong Calla Lily seems most appropriate in light of our mission."
The group has recently bought C-103, a reformulation of Orlistat, and assets from 40J's LLC.
M Pharma is also scheduled to launch its Food and Drug Administration-cleared fertility product branded as ToConceive some time in September this year.
The name of the parent company remains as it is for now, the company said.
A new corporate website is available on-line.
