IGFBP-2 Vaccine to Prevent Ovarian Cancer Progression in Patients With Serologic Detection of Recurrence

Fallopian Tube Carcinoma · Ovarian Carcinoma · Primary Peritoneal Carcinoma

This phase II trial studies how well giving the insulin-like growth factor binding protein 2 \[pUMVC3-hIGFBP-2 multi-epitope plasmid deoxyribonucleic acid (DNA) (IGFBP-2)\] vaccine after one dose of carboplatin works to stop ovarian cancer from growing, spreading, or getting worse (progressing) in patients whose cancer recurrence is detected only in the blood (serologic detection) following treatment with platinum chemotherapy. IGFBP-2 is a protein found in ovarian cancer cells. The IGFBP-2 vaccine may help the body build an effective immune response to kill tumor cells. Carboplatin is in a class of medications known as platinum-containing compounds. It has been shown to activate parts of the immune system that may act against tumors. Giving the IGFBP-2 vaccine after a single dose of carboplatin may be an effective way to stop ovarian cancer from progressing in patients with serologic detection following treatment with platinum chemotherapy.

A Study to Learn About a Clostridioides Difficile Vaccine in People 65 Years of Age and Older

Clostridoides Difficile Associated Disease

The purpose of the study is to learn about how effective, safe, and tolerable the Clostridioides difficile (C. difficile) vaccine is in decreasing the number of C. difficile infections (pCDI) in adults 65 years of age or older. The participants will receive either the C. difficile vaccine or placebo (saline). A placebo does not contain any active ingredients. The vaccines will be given as a shot into the upper arm muscle. This study looks at the number of diarrhea (loose stools) events related to a C. difficile infection, so the length of the study can change. If these events happen quickly, the study may finish sooner; if they happen slowly, it could take longer. Sometimes, the study might stop early if the vaccine clearly does not work. Participants will stay in the study until enough events have occurred to answer the main question. On average, each person is expected to take part for up to about three and a half years. During this time, participants will have 3 planned clinic visits and 3 planned phone visits. After these visits, more scheduled clinic visits will happen every year until the end of study. Besides the scheduled study visits, if at any time during the study a participant has 3 or more loose stools in 24 hours, they will be asked to save the next one (the fourth or later) and contact the study site. The study site will check to see if it could be a C. difficile infection. This check may happen at the clinic or through a phone or video call.

BEATRIX: A Study to Learn About a Group B Streptococcus Vaccine in Healthy Pregnant Women and Their Babies

Healthy

BEATRIX (group B strEptococcus mATeRnal and Infant VaX study) The purpose of this study is to learn about the safety and how the group B streptococcus (GBS) vaccine works in pregnant women and their babies. This study is seeking healthy pregnant participants: * aged 49 or younger who can join. * between 24 and 36 weeks of gestation ("Gestational age" is a medical term used to describe how far along your pregnancy is) * had a fetal ultrasound examination performed with no major fetal abnormalities observed * documented negative for HIV, syphilis and Hepatitis B All participants in this study will receive only 1 shot in an arm. This could either be a group B streptococcus 6-valent polysaccharide conjugate vaccine (GBS6) or placebo. Placebo is an inactive substance used in the study for comparison purposes; in this study, the placebo injection will be saline (saltwater). The pregnant participants may take part in this study for a maximum of 14 months (6 months after delivery) , and their babies for about 12 months after they are born. The pregnant participants will need to visit the research site at least 3 to 4 times with some visits permitted to occur over the telephone. A subset of infants will be asked to take part in the study for up to 19 months. The subset will receive diphtheria toxoid-containing vaccine and/or pneumococcal vaccine following each country's standard immunization plan and have blood drawn 1 month after completion of the primary and/or toddler (booster) doses.

A Clinical Trial Investigating the Safety, Tolerability, and Therapeutic Effects of BNT113 in Combination With Pembrolizumab Versus Pembrolizumab Alone for Patients With a Form of Head and Neck Cancer Positive for Human Papilloma Virus 16 and Expressing the Protein PD-L1

Unresectable Head and Neck Squamous Cell Carcinoma · Metastatic Head and Neck Cancer · Recurrent Head and Neck Cancer

An open-label, controlled, multi-site, interventional, 2-arm, Phase II/III trial of BNT113 in combination with pembrolizumab vs pembrolizumab monotherapy as first line treatment in patients with unresectable recurrent or metastatic HPV16+ HNSCC expressing programmed cell death ligand-1 (PD-L1) with combined positive score (CPS) ≥1. This trial has two parts. Part A, is an initial non-randomized Safety Run-In Phase to confirm the safety and tolerability at the selected dose range level of BNT113 in combination with pembrolizumab. Part B, is a randomized part to generate pivotal efficacy and safety data of BNT113 in combination with pembrolizumab versus pembrolizumab monotherapy in the first line setting in patients with unresectable recurrent or metastatic HPV16+ HNSCC expressing PD-L1 with CPS ≥1. Patients included in the Safety Run-In Phase of the trial (Part A) will not be randomized to Part B and will continue on-trial treatment (BNT113 plus pembrolizumab) within Part A. For Part B, an optional pre-screening phase is available for all patients where patients' tumor samples may be submitted for central HPV16 DNA and central PD-L1 expression testing prior to screening into the main trial. Patients will be treated with BNT113 in combination with pembrolizumab or with pembrolizumab monotherapy for approximately up to 24 months.

A Cancer Vaccine (STEMVAC) in Combination With Chemotherapy for the Treatment of PD-L1 Negative Metastatic Triple-Negative Breast Cancer

Anatomic Stage IV Breast Cancer AJCC v8 · Metastatic Triple-Negative Breast Carcinoma

This phase II trial studies how well a cancer vaccine called STEMVAC works in combination with chemotherapy in treating patients with PD-L1 negative, triple-negative breast cancer that has spread from where it first started (primary site) to other places in the body (metastatic). STEMVAC is designed to target proteins that are expressed on breast cancer stem cells, and it is believed to work by boosting the immune system to recognize and destroy the invader tumor cells that are causing the disease. Chemotherapy drugs work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving STEMVAC in combination with chemotherapy may be an effective treatment for PD-L1 negative metastatic triple-negative breast cancer.
