`4) The Type of Meeting Being Requested:

`
`s) Brief Statement of the P~Jrpose of the Meeting:
`Ongoing LY231514 trials, including the ongoing mesothelioma registration trial H3E-
`MC-JMCH (JMCH for brevity), have been modified through addition of vitamins for
`the purpose of promoting patient safety. The Medical Review Officer does not
`support the addition of vitamins to the ongoing registration trial (FDA
`communications to Lilly on December 21, 1999 and January 6, 2000). The sponsor
`seeks a face-to4ace meeting to resolve this impasse and to come to agreement as
`to the implications of the action of adding vitamins for the pivotal registration trial and
`for supporting trials.
`
`Back.qround:
`Recent multivariate analyses (submission serial numbers 191 on November 8, 1999
`and 194 on November 24, 1999) have shown a strong relationship between high
`baseline homocysteine levels and severe toxicity in the LY231514 trials. In
`response to this information, Lilly initially took the action of excluding patients with
`high baseline homocysteine levels from LY231514 trials (serial no. 194 on
`November 24, 1999). Since external consultants were in unanimous agreement that

`
`the addition of folic acid should lower plasma homocysteine levels and thus offer
`protection to patients, Lilly made the programmatic decision that further development
`of LY231514 would proceed with vitamin supplementation (folic acid together with
`vitamin B12). The decision as to whether this should be applied to an ongoing
`registration trial was carefully considered. We have seen a significant number of
`cancer patients who present with high homocysteine levels, particularly in
`mesothelioma where this proportion of patients can exceed 40%. At the time of the
`decision, mortality in trial JMCH included 5 deaths on the LY231514 plus cisplatin
`arm (3 possibly drug related and 2 attributed to progressive disease) and 1 death
`(attributed to progressive disease) on the cisplatin alone arm. To promote patient
`safety and to not exclude a significant proportion of patients for whom there is no
`approved chemotherapy, the decision was made to include vitamin supplementation
`in the ongoing mesothelioma trial, JMCH (serial no. 195 on December 3, 1999 and
`serial no. 200 on December 22, 1999 for protocol amendment (c) to JMCH). Vitamin
`supplementation was included in the LY231514 plus cisplatin arm as well as the
`cisplatin alone arm to maintain the integrity of the study design.
`
`The amount of folic acid chosen for supplementation (350 to 1000 Izg per day with
`400 p.g as the recommended dose) approximates the amount of folic acid a patient
`with good dietary habits might be expected to ingest on a daily basis. External
`consultants including an expert in folate metabolism were in agreement that this
`amount of added folic acid should be effective in reducing homocysteine levels but
`these low levels should not be detrimental to efficacy. High homocysteine levels are
`often associated with folic acid deficiency and the addition of relatively small
`amounts of folio acid should lower the homocysteine levels in these patients. Since
`the amount of folic acid that will be administered is low, patients who have normal
`levels of homocysteine should not be affected by the addition of this low level of folic
`acid (400 I~g folic acid is the usual amount found in multivitamins in the U.S.). The
`rationale for these steps will be discussed in the briefing document with reference to
`homocysteine and folic acid in the cardiovascular scientific literature. Additionally
`Lilly will give reasons why it no longer feels that a randomized trial with and without
`vitamins, as has been proposed by DODP, is feasible
`
`6) A List of Specific Objectives/Outcomes Expected from the Meeting:
`
`Lilly will show how the addition of vitamins will not affect the statistical evaluation of
`primary endpoint (survival) in the mesothelioma registration trial, JMCH, and come to
`an agreement with the Agency on the incorporation of vitamins into the analysis plan
`of this study. Lilly also plans to have a discussion and come to agreement as to
`proposed changes for the non-small cell lung supporting tdal. In the End of Phase 2
`meeting for LY231514 held on June 25, 1999, the FDA stated in the minutes (sent to
`Lilly on July 23, 1999) that, "We remind you of our agreement that the randomized
`control trial in NSCLC is essential to support the single randomized control tdal in
`mesothelioma.~

`
`Safety analysis/rationale for vitamin supplementation
`Statistical implications for JMCH endpoints
`Options for supportive trials
`
`8) Draft of Specific Questions Grouped by Discipline:
`
`Statistical and Medical:
`
`Lilly feels that the strength of the evidence in our safety analysis (serial numbers 191
`on November 8, 1999 and 194 on November 24, 1999) identifying patients with
`elevated baseline homocysteine levels who are at increased risk for severe toxicity
`justifies the routine use of folic acid and vitamin B12. In addition, Lilly believes that it
`would be ethically difficult to justify exposing patients in a control arm to increased
`risk of toxicity with LY231514 without the addition of folic acid and vitamin B12. It will
`likely also be no longer feasible to implement such a design, given the likelihood that
`investigators will likely not risk exposing their patients without the addition of the
`vitamins and the likelihood that patients will not sign consent to participate in such a
`trial.
`
`Question #1 Does the FDA agree that a randomized trial comparing patients
`receiving LY231514 with and without vitamins is no longer feasible or
`considered ethical given the demonstrated toxicity risks to LY231514
`patients?
`
`Lilly strongly believes that the addition of low amounts of folic acid will not
`substantially affect the primary endpoint of survival in the ongoin~ mesothelioma
`registration trial, JMCH. For this reason we propose the following for this trial.
`At completion of the current 280 patient trial, all endpoints (survival, time to
`progression, tumor response rate, clinical benefit and safety) will be analyzed as
`currently stated in the protocol
`
`To address the issue of vitamins on safety the following is proposed. For JMCH,
`approximately 130 patients have already entered the trial (this includes patients on
`Arms A and B).
`Arm A is the LY231514 plus cisplatin arm
`Arm B is the cisplatin alone arm
`These patients enrolled before amendment JMCH(c) did not receive vitamin
`supplementation. The remaining patients (both arms) will receive vitamin
`supplementation. There will be a small group of patients who will have entered the
`trial without vitamin supplementation and who will have begun vitamin
`supplementation sometime after receiving their first cycle of therapy. The toxicity in
`these particular patients will be assessed per cycle as described in protocol
`amendment (c) (serial no. 200 on December 22, 1999 and 201 on December 22,
`1999).

`
`
`
`The remaining patients (those who had no vitamin supplementation during their
`entire participation in JMCH and those who were supplemented the entire time they
`participated in JMCH), can be grouped into four categories:
`
`Treatment
`Arm A
`

`
`Group A+vits

`with vitamins
`Ilate patients/
`
`Group B+vits
`cisplatin alone
`with vitamins
`Ilate patients)
`
`Dec. 2, 1999
`
`At the end of the trial (280 qualified patients completed) Lilly proposes to evaluate
`toxicity between early and late patients] in these groups and proceed as follows:
`All endpoints will be analyzed as currently stated in the protocol, and the addition
`of vitamins will be included as a possible cofactor for all analyses.
`Exploratory analyses on toxicity (especially on mortality) for variations between
`early and late patients will be carried out.
`
`Question #2 Is this an acceptable plan for analysis of trial JMCH at
`completion of this presently planned 280 patient trial?
`
`In the End of Phase 2 meeting for LY231514 held on June 25, 1999, the FDA stated
`in the minutes that, %’#e remind you of our agreement that the randomized control
`trial in NSCLC is essential to support the single randomized control trial in
`mesothelioma".
`
`Lilly remains committed to completing a randomized registration study as support for
`the mesothelioma registration trial. Lilly anticipates initiation of registration studies
`for LY231514 in front line NSCLC and in breast cancer in the year 2000.
`
`Due to slow accrual (serial number 186 on October 14, 1999; FDA reply from Dr.
`Robert White to Lilly on Dec. 1,1999) in the present second line NSCLC study
`(H3E-MC-JMBQ comparing LY231514 to vinorelbine) and changes in the practice of
`oncology together with changes in the oncology regulatory landscape (i.e., the
`recent approval of docetaxel for second line NSCLC), Lilly proposes replacing the
`present registration study in second line NSCLC with an entirely new randomized
`registration study for LY231514. We will present details of this trial when the briefing
`document is sent.
