Completed Carroll-Loye Biological Research, Inc. Study LNX-002: Field
Repellency of Two Picaridin-Based Personal Insect Repellents to Black
Flies 

Charge to the Board:

1. 	Is the CLBR study LNX-002 sufficiently sound, from a scientific
perspective, to be used to estimate the duration of complete protection
against black flies provided by the tested repellents? 

2. 	Does available information support a determination that study
LNX-002 was conducted in substantial compliance with subparts K and L 40
CFR Part 26? 

Completed Carroll-Loye Biological Research, Inc. Study LNX-003:
Laboratory Repellency of Two Picaridin-Based Personal Insect Repellents
to Two Species of Ticks 

Charge to the Board:

1. 	Is the CLBR study LNX-003 sufficiently sound, from a scientific
perspective, to be used to estimate the duration of complete protection
against ticks provided by the tested repellents? 

2. 	Does available information support a determination that study
LNX-003 was conducted in substantial compliance with subparts K and L 40
CFR Part 26? 

Revised Product Performance Test Guidelines for Insect Repellents to be
Applied to Human Skin

The Board recommended several changes or clarifications, including:

Removal of the maximum-likelihood method requirement in the data
analysis section;

Clarification of recommendations regarding the use of positive controls,
particularly with respect to the number of controls and the rationale
for including them in the study;

Careful consideration of recommendations regarding the recruitment and
inclusion of so-called ‘vulnerable’ populations, including racial
and ethnic minorities; and

Encouraging the use of study designs that will enable investigators to
collect data that will allow quantitative measurement of the repellent
efficacy during the complete protection period.
