The Centers for Disease Control and Prevention (CDC), Division of HIV Prevention requires an HIV care clinic within a public health network with a clientele of at least 50 persons on injectable cabotegravir long-acting (CAB-LA) (Apretude) pre-exposure prophylaxis (PrEP) for over 6 months. CAB-LA uptake is very low in the United States therefore having a sufficient number of participants on CAB-LA in one clinic to be able to successfully recruit at least 50 participants combined with serving a population with high transmission rates is key. The Dallas County Health and Human Services Sexual Health Clinic has a team of care providers and recognized leaders in HIV preventative care who can support investigation of new CDC-developed assays and manage requested blood spot specimen collection during care visits. This public health clinic incorporates the second-highest rate of sexually transmitted infection in the country with a high-frequency interaction with clientele to be able to recruit participant numbers and achieve the multiple-visit series of test evaluations within the contract period. No other provider has the combined capacity of recruiting persons with HIV or at increased risk of acquiring HIV, together with the high level of recognized expertise in long-acting PrEP care, and with experience in running Institutional Review Board (IRB)-approved protocols. The Dallas County Health Principal Investigaor (PI) is embedded in the patient care workflow to be able to effectively oversee recruiting and testing logistics. The Dallas County Health clinicians and care providers interact closely to manage the study aims, and they have available a nurse dedicated to ensuring evaluation testing and results upload for timely reporting and shipping of specimen to CDC. Dallas County health has th capability of successfully performing these clinical studies to satisfy CDC task orders and is currently the only identified source currently able to provide the required services to the CDC.This notice of intent is not a request for competitive quotations; however, all Quotations/ responses received within 15 days of the issuance of this notice shall be considered by the government.
