NCT ID: NCT03989102 Completed - Malaria Clinical Trials

Safety, Immunogenicity, and Protective Efficacy of Radiation Attenuated Plasmodium Falciparum NF54 Sporozoites (PfSPZ Vaccine) During Malaria Transmission Season in Healthy African Adult Women of Childbearing Potential in Mali

Start date: July 3, 2019
Phase: Phase 2
Study type: Interventional

Background: Malaria is a disease spread by mosquitos. Pregnant women are highly susceptible to malaria. This can lead to poor health outcomes for pregnant women and their babies. Researchers want to test a malaria vaccine in women of child bearing potential (WOCBP) and pregnant women. This has not been done before. Objective: To assess the safety and tolerability of PfSPZ vaccine in healthy Malian WOCBP. Eligibility: Healthy women ages 18 38 who live in Ouelessebougou, Mali, and surrounding villages Design: Participants will be screened with: - Physical exam - Medical history - Blood, urine, and heart tests - Multiple-choice test about malaria Participants will get 3 injections by needle into a vein of the study vaccine or a placebo. All 3 will be within 1 month. They will not know whether they receive the vaccine or placebo. Participants will receive treatment to prevent malaria. This will be about 2 weeks before the first and third injections. After the third injection, participants will be followed for about 1 year. They will be tested to see if the vaccine is safe and protects against malaria infection. They will have blood tests. If participants get a rash or injection site reaction, photos of the site may be taken. Any women who become pregnant during the trial will be followed through the end of pregnancy. Babies and their mothers will be followed through the first year of life

NCT ID: NCT03964012 Completed - Clinical trials for Meningococcal Meningitis

Study to Assess Immunegnicity & Safety of Pentavalent Meningococcal Vaccine (NmCV-5)

Start date: August 20, 2019
Phase: Phase 3
Study type: Interventional

This observer-blind, randomized, active controlled trial will be conducted among 2-29 year olds in two sites (Mali and The Gambia). The objectives of the study are to assess and compare the immunogenicity and safety of NmCV-5 with that of Menactra. A total of 1800 eligible participants (who or their parents/guardians have given written informed consent) will be randomised 2:1 (NmCV-5: Menactra) in each of the three age strata 18-29 years, 11-17 years & 2-10 years (400 NmCV-5 recipients & 200 Menactra recipients in each age strata). Each subject will receive a single dose of study vaccine and will be followed up for 6 months post vaccination during which solicited reactions (for seven days), unsolicited AEs (28 days) and SAEs (until the end of study i.e. 168 days after vaccination) will be collected. A blood sample will be collected at baseline (pre-vaccination) and at day 28 post-vaccination for immunogenicity assessment by a Serum Bactericidal Activity assay using rabbit complement (rSBA).

Start date: April 24, 2019
Phase: Phase 2
Study type: Interventional

Background: Malaria affects many people in Mali and other parts of Africa. It is spread by mosquito bites. Malaria can make people sick or can lead to death. Scientists want to learn if a vaccine can stop it from spreading to other people. Objective: To test how well an experimental malaria vaccine works to decrease malaria infections. Eligibility: Healthy people ages 5 and older who live in Doneguebougou, Mali, and surrounding areas Design: Participants will be screened with: Medical history Physical exam Blood, urine, and heart tests EKG Participants will be randomly assigned to get either the experimental vaccine or an approved vaccine. They will not know which they are getting. Participants will have a visit about a week before their first vaccine. They will take a medicine that kills malaria. They will take it at the clinic the next 2 days. Participants ages 5-8 will take the drug again 2 weeks before their third vaccine. Participants get the vaccine through a needle in the arm. They will have visits 1, 3, 7, and 14 days after. They will have blood tests or finger pricks. Participants will get another vaccine 1 and 6 months later. Participants will have blood tests once a month. At these visits they may also have urines tests or mosquito feeds. For the feeds a cup full of mosquitoes will be placed on arms or legs for 15-20 minutes. Participants will have visits twice a month for 4 months after their last vaccine.

Phase: Phase 2
Study type: Interventional

This is a phase II, randomized, double-blind, active-controlled study to evaluate the safety, immunogenicity, and effect on infant immune responses of a single dose of Tetanus diphtheria acellular pertussis vaccine (Tdap) in pregnant women in Mali. 200 healthy pregnant women, ages 18 through 39 years, inclusive, who meet all eligibility criteria will be randomly allocated in a 2:1 ratio to receive either Tdap (BOOSTRIX) or Tetanus diphtheria toxoid (Td) at 14 0/7 weeks through 26 6/7 weeks estimated Gestational Age (GA). For the fetuses of pregnant subjects, GA will be established by ultrasound, whenever possible, in combination with date of last menstrual period (LMP), when available, and fundal height. Study duration is 21 months: approximately 2 months in the start-up period, 6 months enrolling subjects, and 13 months (3-7 months while pregnant and 6 months postpartum) from last subject vaccinated until she and her infant complete follow-up. The primary objectives of this study are: 1) to assess the safety and tolerability of a single 0.5 mL intramuscular injection of BOOSTRIX in pregnant women; 2) to assess the safety of a single maternal BOOSTRIX vaccination on the fetus and infant; 3) to assess the level of Pertussis Toxin (PT) antibody at birth among infants whose mothers received a single dose of BOOSTRIX or Td while pregnant.

NCT ID: NCT03510481 Completed - Malaria Clinical Trials

Safety, Immunogenicity, and Protective Efficacy of Two Regimens of Radiation Attenuated Plasmodium Falciparum NF54 Sporozoites (PfSPZ Vaccine) During Natural Transmission Season in Healthy African Adults in Mali

Start date: May 14, 2018
Phase: Phase 1
Study type: Interventional

Background: The disease malaria affects many people in Mali and other parts of Africa and the world. It is caused by germs spread by mosquito bites. Malaria may be mild. But it can also be serious or lead to death if it is not treated promptly. Researchers want to find a safe vaccine that prevents malaria. Objective: To study how safe and tolerable the malaria vaccine called PfSPZ Vaccine is for healthy adults. Eligibility: Healthy adults: - ages 18-35 in Ouelessebougou, Mali - not infected with HIV, hepatitis B, or hepatitis C - for females, not pregnant or breastfeeding and must use reliable birth control during the study Design: Participants will be screened with questions about malaria and will undergo blood, urine, and heart tests. Participants will be randomly assigned to 1 of 4 groups. They will get injections of either the PfSPZ Vaccine or a salt-water placebo. They will not know which one they get. Vaccinations will occur leading into the malaria transmission each year with 3 injections leading into Year 1 (malaria transmission season in 2018) and 1 injection prior to Year 2 (malaria transmission season 2019). One vaccine group and one placebo group will get an injection 3 times over 4 weeks with an additional vaccination ~10 months later. The other two groups (vaccine group and placebo) will get an injection 3 times over 16 weeks with an additional vaccination ~10 months later. All participants will be treated with an antimalarial medication prior to the third injection and prior to fourth injection. They will be followed for approximately 6 months after third and fourth injection. At vaccine visits, female participants will have a pregnancy test before injection. All participants will have an arm cleaned and the vaccine injected in a vein. They will be watched for 30 minutes. At non-vaccine visits, participants will have a physical exam and be asked how they are feeling. They will usually have blood tests.
