InforMedix and invivodata Partner to Deliver Med-eMonitor System to Global Clinical Trials Market

ROCKVILLE, MD and PITTSBURGH, PA- June 22, 2005 -- InforMedix Holdings, Inc. (OTCBB: IFMX) and invivodata, inc. (www.invivodata.com), today announced a strategic partnership for the marketing, sale, distribution, and implementation support of InforMedix's Med-eMonitor(tm) System to invivodata's global base of pharmaceutical and biotech company clients. The collaboration combines a highly effective solution for managing patient drug safety and dose-response data in clinical trials, with a market leader in providing electronic Patient Reported Outcomes (ePRO) solutions to the global clinical trials market. Trial sponsors will benefit from having a choice of appropriate tools to collect critical data directly from patients.

According to the terms of the agreement, invivodata will deliver InforMedix's Med-eMonitor System as an integral part of its product line, worldwide. invivodata's current ePRO solutions include DiaryPRO(tm), a handheld electronic diary, and SitePRO(tm), a site-based data collection tool for capturing PRO data. Both of these products include access to the industry's leading patient and site management system for ePRO data, which gives researchers and sponsors visibility into study progress and improves trial efficiencies. invivodata is the undisputed leader in the appropriate use of proven methodologies and technologies to collect valid PRO data. As a result, invivodata leads the industry in the delivery of proven clinical research results and consistent business growth, as demonstrated by their recently completed 11th consecutive quarter of revenue growth.

invivodata will offer the Med-eMonitor System to its growing client base, particularly to those sponsors conducting clinical trials requiring medication adherence and patient dose-response data. A number of invivodata's clients have requested a solution that provides Med-eMonitor's range of functionality.

InforMedix will grant invivodata limited exclusive rights among eDiary providers to distribute the Med-eMonitor System in the clinical trials market. invivodata will also provide clinical trial implementation services including training, field support, and first-level help desk support to clients who use Med-eMonitor in a trial. Through cooperative development, both companies will contribute to integration efforts between InforMedix's Med-eMonitor and Med-eXpert Systems and invivodata's back end trial management system.

Dr. Bruce Kehr, CEO of InforMedix commented: "We are very excited to partner with invivodata, a leader in ePRO solutions for the global clinical trials market. invivodata's strong reputation within the pharmaceutical and biotech industries will support our efforts to expand the distribution of our proprietary solution. invivodata's capabilities as a global implementation partner for the clinical trials market allows InforMedix to focus more resources into providing products and services to the disease management and home healthcare markets."

Doug Engfer, President and CEO of invivodata stated, "The addition of the Med-eMonitor System to our product portfolio offers our clients a unique combination of ePRO capabilities with medication dispensing to enhance medication compliance, and drug safety monitoring and reporting to improve patient safety. We view this partnership as an opportunity to further expand our strength in this arena and continue our rapid revenue growth."
