This study will evaluate whether administration of two investigational malaria vaccines (257049 and Ad35.CS.01 vaccines) combined in one immunization schedule increases protection against malaria infection as compared to protection induced by the 257049 vaccine alone. The study will also evaluate the safety and the immune response to the new combination of the two experimental malaria vaccines.

A Phase I/IIa, Double-blind, Randomized, Placebo-controlled, Dose-escalation Clinical Study Evaluating Safety, Tolerability and Immunogenicity of Two Dose Levels of Recombinant Adenoviral Serotype Ad35 and Serotype Ad26 Vectors Expressing the Malaria Plasmodium Falciparum Circumsporozoite Antigen Administered as Heterologous Prime-boost Regimen, and Assessing Protective Efficacy of the Higher Dose in a Malaria Challenge Model in Unblinded Conditions

The purpose of this study is to assess the safety, tolerability and immunogenicity of two dose levels (1x10^10 and 5x10^10 virus particles (vp)) of the adenovirus serotype (Ad) Ad35.CS.01/Ad26.CS.01 prime-boost malaria candidate vaccine, followed by an evaluation of the protective efficacy of the higher dose level in an experimental malaria challenge.
The study will be in 3 phases:
a dose escalation / vaccination phase in which both dose levels will be tested
a malaria challenge phase in which only subjects receiving the Ad35.CS.01/Ad26.CS.01 5x10^10 vp dose level, together with six infectivity control subjects, will be exposed to experimental challenge with Plasmodium falciparum
a long term follow up phase in which all subjects who received active vaccine from both dose levels and/or malaria challenge will be included

Malaria results in over 650,000 deaths each year; thus, there is an urgent need for an effective vaccine. Pre-clinical studies and recently reported human trials suggest that pre-erythrocytic stage vaccines can provide protection against infection. A Phase 1, randomized, placebo-controlled, dose-escalation study was conducted with a vaccine composed of a replication-deficient adenovirus-35 backbone with P. falciparum circumsporozoite (CS) surface antigen (Ad35.CS.01). Healthy adult subjects received three doses of 10 (8), 10 (9), 10 (10), or 10 (11) vp/mL Ad35.CS.01 vaccine or saline placebo intramuscularly at 0, 1, and 6-mo intervals. Adverse events were assessed and anti-CS antibody responses were determined by ELISA. Seventy-two individuals were enrolled, with age, gender, and ethnicity similar across each study arm. While the vaccine was generally well tolerated, adverse events were more frequent in the highest dose groups (10 (10) and 10 (11) vp/mL). More robust humoral responses were also noted at the highest doses, with 73% developing a positive ELISA response after the three dose series of 10 (11) vp/mL. The Ad35.CS.01 vaccine was most immunogenic at the highest dosages (10 (10) and 10 (11) vp/mL). Reactogenicity findings were more common after the 10 (11) vp/mL dose, although most were mild or moderate in nature and resolved without therapy.

BACKGROUNDAd35.CS.01 is a pre-erythrocytic malaria candidate vaccine. It is a codon optimized nucleotide sequence representing the P. falciparum circumsporozoite (CS) surface antigen inserted in a replication deficient Adenovirus 35 backbone. A Phase 1a trial has been conducted in the USA in naïve adults and showed that the vaccine was safe. The aim of this study is to assess the safety and immunogenicity of ascending dosages in sub Saharan Africa.METHODSA double blind, randomized, controlled, dose escalation, phase Ib trial was conducted in a rural area of Balonghin, the Saponé health district (Burkina Faso). Forty-eight healthy adults aged 18-45 years were randomized into 4 cohorts of 12 to receive three vaccine doses (day 0, 28 and 84) of 10(9), 10(10), 5X10(10), 10(11) vp of Ad35.CS.01 or normal saline by intra muscular injection. Subjects were monitored carefully during the 14 days following each vaccination for non serious adverse events. Severe and serious adverse events were collected throughout the participant study duration (12 months from the first vaccination). Humoral and cellular immune responses were measured on study days 0, 28, 56, 84, 112 and 140.RESULTSOf the forty-eight subjects enrolled, forty-four (91.7%) received all three scheduled vaccine doses. Local reactions, all of mild severity, occurred in thirteen (27.1%) subjects. Severe (grade 3) laboratory abnormalities occurred in five (10.4%) subjects. One serious adverse event was reported and attributed to infection judged unrelated to vaccine. The vaccine induced both antibody titers and CD8 T cells producing IFNγ and TNFα with specificity to CS while eliciting modest neutralizing antibody responses against Ad35.CONCLUSIONStudy vaccine Ad35.CS.01 at four different dose levels was well-tolerated and modestly immunogenic in this population. These results suggest that Ad35.CS.01 should be further investigated for preliminary efficacy in human challenge models and as part of heterologous prime-boost vaccination strategies.TRIAL REGISTRATIONClinicalTrials.gov NCT01018459 http://clinicaltrials.gov/ct2/show/NCT01018459.

METHODSIn an observer blind, phase 2 trial, 55 adults were randomized to receive one dose of Ad35.CS.01 vaccine followed by two doses of RTS,S/AS01 (ARR-group) or three doses of RTS,S/AS01 (RRR-group) at months 0, 1, 2 followed by controlled human malaria infection.RESULTSARR and RRR vaccine regimens were well tolerated. Efficacy of ARR and RRR groups after controlled human malaria infection was 44% (95% confidence interval 21%-60%) and 52% (25%-70%), respectively. The RRR-group had greater anti-CS specific IgG titers than did the ARR-group. There were higher numbers of CS-specific CD4 T-cells expressing > 2 cytokine/activation markers and more ex vivo IFN-γ enzyme-linked immunospots in the ARR-group than the RRR-group. Protected subjects had higher CS-specific IgG titers than non-protected subjects (geometric mean titer, 120.8 vs 51.8 EU/ml, respectively; P = .001).CONCLUSIONSAn increase in vaccine efficacy of ARR-group over RRR-group was not achieved. Future strategies to improve upon RTS,S-induced protection may need to utilize alternative highly immunogenic prime-boost regimens and/or additional target antigens.TRIAL REGISTRATIONClinicalTrials.gov NCT01366534.
