We are currently enrolling participants for a decentralized clinical research study to gather more information about the efficacy of a stool-based test in identifying the presence of colorectal cancer (CRC) and advanced precancerous lesions (APL) that may cause cancer in the future.
Participants will complete the at-home test in the privacy and comfort of their home within 60 days before a scheduled preventative colonoscopy. If eligible, you may receive compensation for your time.
You may qualify if you:
· Are 45 years or older
· Have been advised to undergo or have scheduled a screening colonoscopy
· Able to provide a stool sample within 60 days prior to your colonoscopy
· Are willing to undergo a colonoscopy and share the medical report
· Are at average risk for colorectal cancer
You may not qualify if you:
· Have a personal or family history of colorectal cancer or advanced adenomas
· Have been diagnosed with inflammatory bowel disease or a genetic condition associated with higher CRC risk (e.g., Lynch Syndrome)
· Have previously been diagnosed with CRC or adenomatous polyps
This study is now actively enrolling participants nationwide.

Women's Health Contraceptive Study
The purpose of this study is to evaluate the contraceptive effectiveness of Ovaprene, an investigational monthly, hormone-free vaginal ring contraceptive. All participants will be expected to use Ovaprene for 13 consecutive menstrual cycles as their main form of contraception.
Here’s a brief overview of how the study will work:
For approximately 13 months, you will receive Ovaprene at no cost to you. You will be instructed to insert Ovaprene at the end of each cycle, no later than 5 days after the cycle began. Each Ovaprene is intended to provide protection over 29 days of use. Throughout the course of the study, participants will attend regularly scheduled site visits where a medical professional will assess your health and safety.
