                                     PART I
                             REGISTRANT INFORMATION

    Full Name of Registrant:  Interleukin Genetics, Inc.

    Former Name if Applicable:

    Address of Principal Executive Office (Street and Number): 135 Beaver Street

    City, State and Zip Code:  Waltham, MA  02452





                                     PART II
                             RULES 12b-25(b) AND (c)

If the subject report could not be filed without unreasonable effort or expense
and the registrant seeks relief pursuant to Rule 12b-25(b), the following should
be completed. (Check box if appropriate)

             (a)  The reasons described in reasonable detail in Part III of
                  this form could not be eliminated without unreasonable effort
                  or expense;

     [X]     (b)  The subject annual report, semi-annual report, transition
                  report on Form 10-K, 10-KSB, 20-F, 11-K or Form N-SAR, or
                  portion thereof will be filed on or before the 15th calendar
                  day following the prescribed due date; or the subject
                  quarterly report or transition report on Form 10-Q, 10-QSB, or
                  portion thereof will be filed on or before the fifth calendar
                  day following the prescribed due date; and

             (c)  The accountants statement or other exhibit required by
                  Rule 12b-25(c) has been attached if applicable.

         PART III NARRATIVE

         State below in reasonable detail the reasons why Form 10-K and 10-KSB,
         20-F, 11-K, 10-Q and 10-QSB, N-SAR, or the transition report or portion
         thereof could not be filed within the prescribed period.

The Registrant could not file its Quarterly Report on Form 10-Q for the three
months ended June 30, 2002 within the prescribed time period without
unreasonable effort or expense because the Registrant recently engaged a new
independent auditor, Grant Thornton LLP, to replace its former independent
auditor, Arthur Andersen LLP. Accordingly, management and the new independent
auditor need additional time to complete their review of the Registrant's
financial results for the three months ended June 30, 2002 before finalizing and
filing the Registrant's Quarterly Report on Form 10-Q.

                                     PART IV

PART IV -- OTHER INFORMATION

Item (3) -- Change in Results of Operations.

            The Registrant currently anticipates that the unaudited financial
statements to be included in its Quarterly Report on Form 10-Q for the
three-month period ended June 30, 2002 ("Second Quarter 2002") will reflect
that:

           -      The Registrant generated total revenues of $13,540 in Second
                  Quarter 2002 as compared to total revenues of $118,654 for the
                  three-month period ended June 30, 2001 ("Second Quarter
                  2001"), a $105,114, or 89%, decrease in total revenues
                  primarily attributable to the inclusion in Second Quarter 2001
                  revenues of $90,720 for the processing of 1,008 tests in
                  association with a single clinical trial that was conducted by
                  Washington Delta Dental, a reduction in the number of tests
                  processed exclusive of that clinical trial and a change in
                  distributors for out PST product;

           -      The Registrant's research and development expenses for Second
                  Quarter 2002 increased by $147,908, or 21%, to $850,179,
                  compared to $702,271 for Second Quarter 2001, primarily due to
                  an increased number of ongoing clinical projects, the staffing
                  of a new laboratory and the cost of supplying the laboratory;

           -      The Registrant's selling, general and administrative expenses
                  for Second Quarter 2002 decreased by $50,983, or 8%, to
                  $569,240, compared to $620,223 for Second Quarter 2001,
                  primarily due to a reduction in administrative, sales and
                  marketing expenses related to the sale and distribution of PST
                  and a decrease in travel, legal and recruiting expense,
                  partially offset by increases in rent and expenses related to
                  business development efforts;

           -      The Registrant's interest income for Second Quarter 2002
                  decreased to $6,752, compared to $79,589 in Second Quarter
                  2001 primarily due to the decrease in funds available for
                  investment; and

           -      The Registrant realized a net loss of $1,402,326, or $0.07 per
                  share, for Second Quarter 2002 as compared to a net loss of
                  $1,146,149, or $0.05 per share, for Second Quarter 2001.
