RV 507 was a Phase I, open-label study to examine the safety, tolerability and immunogenicity of an investigational Marburg vaccine given by intramuscular (IM) injection to healthy adults. The study was a dose escalation of VRC-MARADC087-00-VP, a chimpanzee adenovirus serotype 3 (cAd3) vector vaccine, which encodes wild type (WT) glycoprotein (GP) from Marburgvirus.
A total of 40 participants were evenly split, with 20 in each of the two dosage groups, to receive the investigational cAd3-Marburg vaccine at a dose of either 1x10^10 particle units (PU) (Group 1) or 1x10^11 PU (Group 2). The dose escalation plan included daily review of any new safety data by a study clinician, regular review of safety data by the protocol team and a staged enrollment plan with required interim safety reviews. The study began with enrollment of 3 participants into Group 1 (1x10^10 PU) at a rate of 1 participant per day. After at least 7 days of follow-up for the first 3 vaccinated participants, an interim safety review occurred before enrollment of additional participants into the group. No safety issues were identified; therefore, an additional 17 participants were enrolled to complete Group 1. When there was a minimum of seven days of follow-up safety data from the last enrolled participant in Group 1, an interim safety review occurred. Once no safety issues were identified, enrollment of participants into the next dose level began with the enrollment of 3 participants at a rate of 1 participant per day. After at least 7 days of follow-up for the first 3 vaccinated participants in Group 2 (1x10^11 PU), an interim safety review occurred before the enrollment of additional participants into Group 2. No safety issues were identified and an additional 17 participants were enrolled to complete Group 2. Participants were followed for approximately 48 weeks.

Solicited adverse events (AEs) were reported for 7 days after the study product administration. Unsolicited AEs were recorded from receipt of the study product administration through the visit scheduled for 28 days after study product administration. At other time periods greater than 28 days after the study product administration, only serious AEs (SAEs), and new chronic medical conditions that required ongoing medical management were recorded through the last study visit.
All AEs recorded on the study were reported. Solicited AEs collected through systematic assessment and unsolicited AEs collected through non-systematic assessment are reported for participants who received study product and had safety data collected following the product administration. Data represent the number and percentage of participants experiencing the event. A participant with multiple experiences of the same event is counted once using the event of worst severity.

Labs included hematology (hemoglobin, hemoglobin change from baseline, hematocrit percent, mean corpuscular volume (MCV), platelets, and white blood cell (WBC), red blood cell (RBC) and lymphocyte counts) and chemistry (alanine aminotransferase (ALT) and creatinine). Complete blood count (CBC) with total lymphocyte count results were collected at screening (≤ 56 days before enrollment), Day 0 prior to study product administration (baseline), Day 3, and Weeks 2, 4, 8 and 24. Creatinine and ALT results were collected at screening, Day 0, Day 3 and Weeks 2, 4 and 8. Institutional laboratory normal ranges as well as the Toxicity Grading Scale for Healthy Adult and Adolescent Volunteers Enrolled in Preventative Vaccine Clinical Trials FDA Guidance, September 2007 were used. | Through 48 weeks after study product administration |
| Number of Participants With One or More Unsolicited Non-Serious Adverse Events (AEs) | Unsolicited AEs and attribution assessments were recorded in the study database from receipt of the study product administration through the visit scheduled for 28 days after study product administration. At other time periods greater than 28 days after the study product administration, only serious AEs (SAEs reported as a separate outcome and in the AE module), and new chronic medical conditions that required ongoing medical management were recorded through the last study visit. The relationship between an AE and the study product was assessed by the investigator based on clinical judgment and the definitions outlined in the protocol. A participant with multiple experiences of the same event is counted once using the event of worst severity. | Through 28 days after study product administration |
| Number of Participants With Serious Adverse Events (SAEs) | SAEs were recorded from receipt of the study product administration through the last expected study visit at Week 48. The relationship between a SAE and the study product was assessed by the investigator based on clinical judgment and the definitions outlined in the protocol. A participant with multiple experiences of the same event is counted once using the event of worst severity. | Through 48 weeks after study product administration |

| Percentage of Participants With a Positive Marburg-Specific Antibody Response After the cAd3-Marburg Vaccine Administration | A positive response occurs if there is a significant increase in the ELISA post vaccination compared to baseline. For each participant, a t-test was performed to compare the post vaccination titers versus those at baseline. A participant is defined as a positive responder if the one-sided t-test has a p-value < 0.05. | Through 28 days after study product administration |
| Magnitude of Marburg-Specific Antibody Responses After the cAd3-Marburg Vaccine Administration | Geometric mean titer (GMT) was calculated along with 95% confidence intervals at Week 4 for each dose group. | Through 28 days after study product administration |
| Percentage of Participants With Positive Marburg-specific T Cell Responses After the cAd3-Marburg Vaccine Administration | T cell response was measured by Intracellular Cytokine Staining (ICS) assays using Peripheral Blood Mononuclear Cells (PBMCs) at 4 weeks after vaccination. The percentage of participants with T cell responses with Clopper-Pearson 95% Confidence Intervals are presented. Positivity is defined as a response over calculated thresholds determined by the trial statistician. | Through 28 days after study product administration |
| Magnitude of Marburg-specific T Cell Responses After the cAd3-Marburg Vaccine Administration | Median and interquartile ranges presented for total cytokine responses for both CD4 and CD8 memory T cells based on a T cell response with any cytokine at Week 4 for each dose group. | Through 28 days after study product administration |

|
| Secondary | Percentage of Participants With Positive Marburg-specific T Cell Responses After the cAd3-Marburg Vaccine Administration | T cell response was measured by Intracellular Cytokine Staining (ICS) assays using Peripheral Blood Mononuclear Cells (PBMCs) at 4 weeks after vaccination. The percentage of participants with T cell responses with Clopper-Pearson 95% Confidence Intervals are presented. Positivity is defined as a response over calculated thresholds determined by the trial statistician. | All participants who received the cAd3-Marburg vaccine. | Posted | Number | 95% Confidence Interval | Percentage of responders | Through 28 days after study product administration |

|
| Secondary | Magnitude of Marburg-specific T Cell Responses After the cAd3-Marburg Vaccine Administration | Median and interquartile ranges presented for total cytokine responses for both CD4 and CD8 memory T cells based on a T cell response with any cytokine at Week 4 for each dose group. | All participants who received the cAd3-Marburg vaccine. | Posted | Median | Inter-Quartile Range | percent of subset | Through 28 days after study product administration |
