Study Overview

This clinical trial focuses on testing the efficacy of different digital interventions to promote re-engagement in cancer-related long-term follow-up care for adolescent and young adult (AYA) survivors of childhood cancer.

Description

A Phase 1, open label clinical study to evaluate the safety, immunogenicity, tolerability and efficacy of Plasmodium falciparum Malaria Protein 013 (FMP013) combined with (ALF with QS-21), saponin molecule derived from the bark of Quillaja species (ALFQ)) in healthy adult volunteers at different doses and dosing schedules.

Able and willing to comply with all research requirements, in the opinion of the Investigator; 4. Agreement to refrain from blood donation during the course of the study. Volunteers who have undergone CHMI can donate to other research once the study is complete but cannot donate to the American Red Cross for at least 3 years after the CHMI event; 5. Laboratory Criteria within 90 days before enrollment: * Hemoglobin ≥ 11.7 g/dL for women; ≥ 12.0 g/dL for men; * White Blood Cell count = 3,800-10,800 cells/mm3; * Platelets = 140,000-400,000/mm3; * Alanine aminotransferase (ALT; SGPT) 9-46 U/L male and 6-29 U/L female; * Serum creatinine ≤ 1.5 mg/dL; * Negative HIV testing (HIV Ab / antigen 4th generation screen with reflex confirmatory RNA testing); * Negative hepatitis B surface antigen (HBsAg) and hepatitis C antibody testing; Note: As above, Grade 1 lab abnormalities detected on screening may be repeated at PI discretion. Persistent Grade 1 abnormalities that are felt to represent the non-pathologic baseline for the subject will be discussed with the research monitor and documented before a subject is enrolled in the trial, and are allowable per discretion and agreement of the PI and Research Monitor 6. Birth control requirements: * No reproductive potential due to post-menopausal status (12 months of natural \[spontaneous\] amenorrhea) or hysterectomy, bilateral oophorectomy or tubal ligation; * Women of childbearing potential should agree to practice highly effective contraception at least 30 days before enrollment and through 3 months post-CHMI or post-last vaccination (whichever is latest), using one of the following methods: condoms (male or female) with spermicide; diaphragm, or cervical cap with spermicide; intrauterine device; contraceptive pills, patch, injection, intravaginal ring or other FDA-approved contraceptive method; male partner has previously undergone a vasectomy; abstinence. 7. For all female subjects except those with a history of hysterectomy or bilateral oophorectomy, a negative β-HCG pregnancy test (urine) on day of enrollment, each day of vaccination, and the day of CHMI (tubal ligations have a not insignificant failure rate, 12 months of spontaneous amenorrhea does not completely preclude pregnancy and can be a result of polycystic ovarian syndrome); 8.
