Overview
The goal of this clinical trial is to learn if an FDA approved drug, Ceftriaxone, given intermittently, can treat people between 18 and 75 years old with a history of Lyme disease, who are still experiencing persistent or returning symptoms after they have completed treatment. The main questions it aims to answer are:
- Will giving Ceftriaxone approximately every 5 days for 6 weeks be safe and well tolerated when compared to a group that receives placebo (a look-alike substance that contains no drug)?
- Will giving Ceftriaxone improve symptoms?
Participants will be asked to do the following:
- Come to the clinic approximately every 5-6 days to receive an IV infusion of either the Ceftriaxone or placebo.
- Answer questions about their level of tiredness, body pain, general health and physical ability, sleep, anxiety, depression and any suicidal thoughts.
- Give blood so we can make sure your body is handling the drug okay or to help us learn more about how the drug is affecting the persistent Lyme disease symptoms.
Description
This study will explore treating participants who are 18 to 75 years old with Post-Treatment Lyme Disease. IV Ceftriaxone will be delivered in a pulse dose fashion, approximately every 5 days for a total of 9 IV infusions over 6 weeks. Participants will return one month following last treatment, at approximately 3 and 6 months from study start. At each study visit, participants will be asked a number of questionnaires including the SAFTEE assessment to assess the side effects of the drug as compared to placebo; the Fatigue Severity Scale, SF-36, GSQ-30, and PROMIS-29 questionnaires to assess physical functioning, general health, vitality, social functioning, bodily pain, role physical, role emotional, mental health, symptoms, fatigue, anxiety, depression, and sleep disturbances; the CSSRS to assess suicidal ideation.
At the 6-month mark, the study will be unblinded and participants in the placebo group will be invited to repeat the study visits receiving Ceftriaxone. Participants who originally received Ceftriaxone will receive a phone call follow up at 1 year. The duration for both groups is one year. Samples will be collected for safety labs and research assessments.

- Diagnosis with Bipolar Disorder or Schizophrenia, hospitalization in the past year for a mental health disorder, or any other psychiatric condition (to include any finding of increased suicide risk as identified by a rating of moderate or high risk on the CSSRS assessment), which in the opinion of the investigator prevents the subject from participating in the study

- Planned travel during the study period that would interfere with the ability to complete all study visits (this can be a temporary exclusion with plan to schedule enrollment during a window of time during which they could attend their study visits)
- Significant screening physical examination abnormalities or chronic medical condition that in the opinion of the investigator may impact subject safety
- 12. Participation (active or follow-up phase) or planned participation in another vaccine, drug, or medical device in the 4 weeks prior to this trial, within 5 times the elimination half-life, whichever is longer, or during the trial
