PRESS RELEASE FROM INDEGENE INC

Titan Pharmaceuticals And Indegene Enter Into Probuphine® Co-Promotion Partnership

Posted Jun 24, 2020

SAN FRANCISCO, June 24, 2020 /PRNewswire/ -- Titan Pharmaceuticals, Inc. (NASDAQ: TTNP) ("Titan" or the "Company") today announced that it has entered into a co-promotion partnership with Indegene Inc. to establish multichannel digital marketing programs throughout the United States and expand the capabilities for the engagement of health care providers ("HCPs") who are eligible to prescribe Titan's Probuphine® (buprenorphine) implant.

Indegene is a leading healthcare solutions company with a unique blend of life sciences domain expertise and state-of-the-art technology capabilities that will complement and help accelerate the build out of the current commercial operations at Titan. Under the terms of the renewable four-year agreement, Indegene's sophisticated multichannel marketing tools, predictive analytics, webinars and social media campaigns will be used along with its dedicated tele-representatives to help expand the universe of Probuphine Risk Evaluation and Mitigation Strategy ("REMS")-certified HCPs and enable further expansion of maintenance treatment with Probuphine for eligible Opioid Use Disorder ("OUD") patients. Titan will continue its ongoing commercial efforts with its field sales and medical liaison personnel who will also provide support to Indegene as needed. Titan will be responsible for all training of HCPs, administration of the REMS program and regulatory affairs.

"This partnership with Indegene further strengthens and expands our Probuphine commercial operations, especially with the COVID-19-related restrictions that have limited in-person HCP outreach capabilities," said Titan's President and CEO, Sunil Bhonsle. "Indegene brings a wealth of business expertise and experience in the digital arena working globally with large and small pharmaceutical companies that is invaluable in today's changing environment. This partnership accelerates the expansion of our capabilities to potentially achieve our goals and enable access to Probuphine for eligible patients suffering from OUD, especially at a time when a six-month maintenance treatment option could be very important in minimizing frequent direct contact."

"We are looking forward to partnering with Titan using our proven AI-driven Next Generation Commercialization Platform," said Gaurav Kapoor, Executive Vice President of Indegene Inc. "This partnership comes at a meaningful time, when the COVID-19 pandemic is exacerbating the opioid crisis while limiting direct engagement with the HCPs that treat OUD patients. I believe the 'new normal' model in pharma commercial operations will start relying just as much on digital programs with remote representatives, as field representatives providing face-to-face interaction. We at Indegene are making significant investments to be at the forefront of this transition and are excited to see Titan embrace this innovative approach."

About Probuphine

Probuphine is the only subdermal implant designed to deliver buprenorphine continuously for six months following insertion.

Probuphine was developed using ProNeura®, the continuous drug delivery system developed by Titan that consists of a small, solid implant made from a mixture of ethylene-vinyl acetate and a drug substance. The resulting construct is a solid matrix that is placed subdermally, normally in the upper inner arm in an outpatient office procedure and removed in a similar manner at the end of the treatment period. The U.S. Food and Drug Administration ("FDA") approved Probuphine in May 2016, and it is the first and only buprenorphine implant available for the maintenance treatment of opioid addiction in eligible patients.
