Vaccines Treatment Options in Houston, TX

This phase IIb trial tests whether Tri-Ad5 in combination with N-803 works to prevent colon and other cancers in participants with Lynch syndrome. Each of the three injections in Tri-Ad5 vaccine contain a different substance that is in precancer and cancer cells. Injecting these substances may cause the immune system to develop a defense against cancer that recognizes and destroys any precancer and cancer cells that produce these proteins in the future. N-803 may increase immune responses to other vaccines. Giving Tri-Ad5 in combination with immune enhancing N-803 may lower the chance of developing colon and other cancers in participants with Lynch syndrome. Read Less

The purpose of this study to evaluate the safety and immunogenicity of a 2-dose regimen of 9vHPV vaccine, where the first dose is administered concomitantly with a first dose of a 2-dose regimen of mRNA-1273 vaccine versus nonconcomitant administration of 9vHPV and mRNA-1273 vaccines in boys and girls 9 to 11 years of age.

This Phase 1/2a trial is a randomized, placebo-controlled trial to evaluate the safety, tolerability and immunogenicity of two ascending doses (10\^6 PFU and 10\^7 PFU) of intranasal BLB-201 (a recombinant parainfluenza virus type 5) administered in infants (8-24 months of age) and children (18-59 months of age) who may or may not have had prior respiratory syncytial virus (RSV) infection.

This is a Phase 2, multicenter, randomized, double-blind placebo controlled, 2-arm study to evaluate the effect of amlitelimab on vaccine antibody responses, and the safety of amlitelimab concurrently administered with non-live vaccines in adult participants with moderate-to-severe atopic dermatitis (AD). The purpose of this study is to compare the immune responses to concomitantly administered Boostrix (tetanus, diphtheria, and acellular pertussis \[Tdap\]) and Pneumovax 23 (PPSV) vaccines in adult participants with moderate-to-severe AD treated with amlitelimab versus placebo. The study will evaluate the percentage of participants achieving a positive anti-tetanus response at Week 16 (primary endpoint) and a positive anti-pneumococcal response at Week 16 (key secondary endpoint). Study details include: The study duration will be up to 36 weeks (for participants not entering the LTS17367 \[RIVER-AD\]). The screening period will be 9 days to 4 weeks. The treatment duration will be up to 16 weeks. The post-treatment safety follow-up period will be16 weeks. The number of visits will be up to 7 (or 6 for those entering LTS17367 \[RIVER-AD\]).

This study is a large-scale investigation (Phase 3) into a new booster shot designed specifically for teenagers. The booster targets a particular variant of COVID-19, Omicron XBB.1.5. The main focus is on safety: researchers want to see if this new booster is safe for teenagers who have already received two doses of the Pfizer or Moderna mRNA COVID-19 vaccines. To ensure a fair comparison, the study will use a double-blind approach. This means two groups of teenagers will receive booster shots, but neither the teenagers nor the researchers giving the shots will know beforehand which version of the booster each person gets. The study will also assess how well the body fights the virus after the booster shot. Read Less

This study includes 3 parts: Parts A, B, and C. The purpose of this study is to evaluate the immunogenicity and safety of mRNA-1010 seasonal influenza vaccine in adults. Read Less

The purpose of this study is to evaluate the immunogenicity, safety, and reactogenicity of mRNA-1083 as compared with active control, co-administered licensed influenza and severe acute respiratory syndrome coronavirus 2 (SARS CoV 2) vaccines, in 2 independent age-group sub-study cohorts, healthy adults 65 years and older (Cohort A) and healthy adults 50 to \<65 years of age (Cohort B).

The purpose of this study is to learn about how the flu and COVID vaccines act when given alone or when mixed together. This study is seeking healthy participants aged 18 or older. All participants in this study will receive only 1 shot to their arm, either a flu or COVID vaccine, alone or mixed. Participants will take part in this study for about 6 months, and participants will need to visit the clinical study site at least 4 times. Read Less

This study aims to assess the immune response and safety of GSK's candidate chickenpox and marketed MMR vaccines when given to children 12 to 15 months of age via a muscle injection. It compares the GSK vaccines to Merck's chickenpox vaccine, administered just under the skin. Additionally, the study will evaluate the immune response and safety of giving the GSK vaccines along with other childhood vaccines through a muscle injection. Read Less

This study is a Phase 3, randomized, modified double-blind study which aims to measure whether the investigational pneumococcal conjugate vaccine PCV21 is safe and can help the body to develop germ-fighting agents called "antibodies" (immunogenicity) when it is given after 1 dose, 2 doses, or 3 doses of a licensed 20-valent pneumococcal vaccine compared to when 20-valent pneumococcal vaccine is given as a complete series in infants aged from approximately 2 months (42 to 89 days). The study duration per participant will be up to approximately 19 months. The study vaccines (either PCV21 or 20vPCV) will be administered at approximately 2, 4, 6 and 12 to 15 months of age (MoA). Routine pediatric vaccines will be given as per local recommendations. There will be 6 study visits: Visit (V)01, V02 separated from V01 by 60 days, V03 separated from V02 by 60 days, V04 separated from V03 by 30 days, V05 at 12 months of age until 15 months of age, V06 separated from V05 by 30 days.

The primary objective of the study is to determine the relative efficacy of the investigational oral severe acute respiratory syndrome coronavirus 2 (SARS-CoV2) vaccine tablet VXA-CoV2-3.3 compared to a currently recommended vaccine for the prevention of symptomatic Coronavirus Disease 2019 (COVID-19). In order to represent a more recently circulating SARS-CoV-2 variant, the main study endpoints will now evaluate the VXA-CoV2-3.3 (KP.2 strain) vaccine, and not the VXA-CoV2-3.1 (XBB.1.5 strain) vaccine.

Brief Summary of Stage 1: The purpose Stage 1 (Phase I/IIa) is to assess the safety and immunogenicity of a single intramuscular (IM) injection of 3 dose-levels of an Respiratory Syncytial Virus (RSV) vaccine candidate formulated with 2 different lipid nanoparticles (LNPs) in healthy adult participants aged between 18 to 50 years, and 60 years and older. The primary objectives of this stage are to assess the safety and immunogenicity profiles across the dose-level groups (low, medium, and high doses) with 2 LNPs. This stage will evaluate the safety and immunogenicity of a booster vaccination administered 12 months after the primary vaccination in a subset of the study population. Brief Summary of Stage 2: The study also also incorporates a Stage 2 (Phase IIa, dose-ranging design) that includes adults aged 60 years and older to assess the safety and immunogenicity of different doses of RSV vaccine encapsulated in one of the LNPs. In the Phase IIa dose-ranging stage, eligible participants will be randomly assigned in a 1:1:1 ratio to receive a single IM administration of RSV vaccine candidate doses, or placebo. Multiple safety analyses will be performed, minimally at D07 and D28. Additional analyses may be performed as data are available. Read Less
