Brief Summary: This study is a single centre single blind placebo step 1 or reference step 2 randomised study Healthy young male volunteers will receive single ascending dose of IMP321 in each step 4 doses tested 3 10 30 and 100 µg In step 1 IMP321 will be given alone and tested versus placebo physiological saline In step 2 the association IMP321 Agrippal commercially available flu vaccine will be tested versus Agrippal alone
Detailed Description: This study is divided in two steps

Step 1 20 volunteers IMP321 will be given alone and tested versus placebo physiological saline

In this first step 4 group doses of four subjects each will be evaluated versus a placebo group of 4 subjects

Group IMP321 alone at 3 µg
Group IMP321 alone at 10 µg
Group IMP321 alone at 30 µg
Group IMP321 alone at 100 µg

In order to complete these groups four successive cohorts of volunteers will be studied

Cohort A will correspond to the dose 3 µg and will include

4 subjects treated by IMP321 3 µg alone
1 subject treated by placebo

If the tolerability of this cohort is acceptable the following cohort will be done

Cohort B will correspond to the dose 10 µg and will include

4 subjects treated by IMP321 10 µg alone
1 subject treated by placebo

If the tolerability of this cohort is acceptable the following cohort will be dose

Cohort C will correspond to the dose 30 µg and will include

4 subjects treated by IMP321 30 µg alone
1 subject treated by placebo

If the tolerability of this cohort is acceptable the following cohort will be done

Cohort D will correspond to the dose 100 µg and will include

4 subjects treated by IMP321 100 µg alone
1 subject treated by placebo

Step 2 40 volunteers The association IMP321 Agrippal will be tested versus the Agrippal alone

In this second step 4 group doses of eight subjects each will be evaluated versus a reference group Agrippal physiological saline of 8 subjects

Group Agrippal 3 µg of IMP321
Group Agrippal 10 µg of IMP321
Group Agrippal 30 µg of IMP321
Group Agrippal 100 µg of IMP321

In order to complete these groups four successive cohorts of volunteers will be studied

Cohort A will correspond to the dose 3 µg of IMP321 and will include

8 subjects treated by Agrippal IMP321 3 µg
2 subjects treated by Agrippal physiological saline

If the tolerability of this cohort is acceptable the following cohort will be done

Cohort B will correspond to the dose 10 µg of IMP321 and will include

8 subjects treated by Agrippal IMP321 10 µg
2 subjects treated by Agrippal physiological saline

If the tolerability of this cohort is acceptable the following cohort will be done

Cohort C will correspond to the dose 30 µg of IMP321 and will include

8 subjects treated by Agrippal IMP321 30 µg
2 subjects treated by Agrippal physiological saline

If the tolerability of this cohort is acceptable the following cohort will be done

Cohort D will correspond to the dose 100 µg of IMP321 and will include

8 subjects treated by Agrippal IMP321 100 µg
2 subjects treated by Agrippal physiological saline

This study will be a single centre single blind placebo step 1 or reference step 2 randomised study

Healthy young male volunteers will receive single ascending dose of IMP321 in each step Treatments will be administered as a subcutaneous injection on the mornings of Day 1 The injection will be done subcutaneously sc in the deltoid area of the non dominant arm

The pharmacokinetic analysis will be performed by IMP321-specific ELISA testing of the samples collected from the 4 volunteers receiving 100 µg IMP321 alone Blood samples will be taken on the morning of Day 1 before dosing then at 05 1 4 24 and 48 h after dosing

Blood samples for T cell assays and serum samples for hLAG-3Ig- and HA-specific antibody detection by ELISA will be taken on the morning of Days 1 29 and 57

Monitoring for the occurrence of adverse events AE changes in physical examination vital signs blood pressure pulse rate respiration electrocardiograms ECG and clinical laboratory tests biochemistry haematology urinalysis will be performed before and after each dose of the study drug to assess safety and tolerability
