detailed evaluations of diabetic nerve pain 

questionnaires that may improve participants understanding their own condition. 
As part of Study CPMP, participants to this ISA will report their experience using standard tools 
that may contribute to the assessment of novel treatments for DPNP. In addition, data collected 
from this study may also improve our understanding of DPNP pathogenesis. Both of which may 
lead to the development of new treatment with improved safety and efficacy profile compared to 
standard of care. 
2.3.3. Overall Benefit Risk Conclusion
Taking into account the measures taken to minimize risk to participants participating in this 
study, the potential risks identified in association with LY3526318 are justified by the 
anticipated benefits that may be afforded to participants with DPNP.

Definitions
Word/Phrase
Definition
Women of 
childbearing 
potential
Females are considered women of childbearing potential (WOCBP) if

they have had at least 1 cycle of menses, or

they have Tanner 4 breast development.
Any amount of spotting should be considered menarche. If Tanner Staging of 
breasts is performed as part of study procedures, please refer to the Reproductive, 
Pregnancy and Pediatrics Safety Committee Safety Guidance for Children in 
Clinical Trial regarding Tanner staging.
Women not of 
childbearing 
potential
Females are considered women not of childbearing potential (WNOCBP) if

they have a congenital anomaly such as Mullerian agenesis 

they are infertile due to surgical sterilization, or 

they are postmenopausal.
Examples of surgical sterilization include: hysterectomy, bilateral oophorectomy, 
or tubal ligation.
Postmenopausal 
state
The postmenopausal state should be defined as:
1.
A woman at any age at least 6 weeks postsurgical bilateral oophorectomy 
with or without hysterectomy, confirmed by operative note; or 
2.
A woman at least 40 years of age and up to 55 years old with an intact 
uterus, not on hormone therapy*, who has had cessation of menses for at 
least 12 consecutive months without an alternative medical cause, AND 
with a follicle-stimulating hormone >40 mIU/mL; or 
3.
A woman 55 or older not on hormone therapy, who has had at least 
12 months of spontaneous amenorrhea; or
4.
A woman at least 55 years of age with a diagnosis of menopause prior to 
starting hormone replacement therapy
* Women should not be taking medications during amenorrhea such as oral 
contraceptives, hormones, gonadotropin-releasing hormone, anti-estrogens, 
selective estrogen receptor modulators (SERMs), or chemotherapy that could 
induce transient amenorrhea.
Reproductive 
Toxicology 
Studies
Embryofetal studies are toxicity studies in pregnant animals designed to identify 
abnormalities in the development of fetuses, which could indicate potential for 
teratogenicity in humans. The relevant dosing period is during organogenesis.

Appendix 4: Provisions for Changes in Study Conduct During 
Exceptional Circumstances
Implementation of this appendix
The changes to procedures described in this appendix are temporary measures intended to be 
used only during specific time periods as directed by the sponsor in partnership with the 
investigator.
Exceptional circumstances
Exceptional circumstances are rare events that may cause disruptions to the conduct of the study. 
Examples include pandemics or natural disasters. These disruptions may limit the ability of the 
investigators, participants, or both to attend on-site visits or to conduct planned study procedures.
Implementing changes under exceptional circumstances
In an exceptional circumstance, after receiving the sponsor’s written approval, sites may 
implement changes if permitted by local regulations. 
After approval by local Ethical Review Boards, regulatory bodies and any other relevant local 
authorities, implementation of these exceptional circumstance changes will not typically require 
additional notification to these groups, unless they have specific requirements in which 
notification is required (for example, upon implementation and suspension of changes). All 
approvals and notifications must be retained in the study records.
If the sponsor grants written approval for changes in study conduct, the sponsor will also provide 
additional written guidance, if needed.
Considerations for making a change
The prevailing consideration for making a change is ensuring the safety of study participants. 
Additional important considerations for making a change are compliance with Good Clinical 
Practice, enabling participants to continue safely in the study and maintaining the integrity of the 
study. 
Informed consent
Additional consent from the participant will be obtained, if required, for:

participation in remote visits, as defined in Section “Remote Visits,”

dispensation of additional study intervention during an extended treatment period, 

alternate delivery of study intervention and ancillary supplies, and

provision of their personal or medical information required prior to implementation of 
these activities. 
Changes in study conduct during exceptional circumstances
Changes in study conduct not described in this appendix, or not consistent with applicable local 
regulations, are not allowed.
The following changes in study conduct will not be considered protocol deviations.


When delivering supplies to a location other than the study site (for example, 
participant’s home), the investigator, sponsor, or both should ensure oversight of the 
shipping process to ensure accountability and product quality (that is, storage 
conditions maintained and intact packaging upon receipt).

Instructions may be provided to the participant or designee on the final disposition of 
any unused or completed study supplies.
Adjustments to visit windows 
Whenever possible and safe to do so, as determined by the investigator’s discretion, participants 
should complete the usual Schedule of Activities as described in the CPMP Master Protocol, 
CPMP(3) DSA, and NP02 ISA. To maximize the possibility that these visits can be conducted as 
on-site visits, the windows for visits may be adjusted, upon further guidance from the sponsor. 
This minimizes missing data and preserves the intended conduct of the study.
For participants whose visits have extended windows, additional study intervention may need to 
be provided to avoid interruption and maintain overall integrity of the study.
Documentation
Sites will identify and document the details of how participants, visit types, and conducted 
activities were affected by exceptional circumstances. Dispensing/shipment records of study 
intervention and relevant communications, including delegation, should be filed with site study 
records.
Source documents generated at a location other than the study site should be part of the 
investigator’s source documentation and should be transferred to the site in a secure and timely 
manner.

A data monitoring committee is a group of independent scientists who are appointed to 
monitor the safety and scientific integrity of a human research intervention, and to make 
recommendations to the sponsor regarding the stopping of a study for efficacy, or for 
harms, or for futility. The composition of the committee is dependent upon the scientific 
skills and knowledge required for monitoring the particular study.

enroll
The act of assigning a participant to a treatment. Participants who are enrolled in the 
study are those who have been assigned to a treatment.

informed consent
A process by which a participant voluntarily confirms his or her willingness to 
participate in a particular study, after having been informed of all aspects of the study 
that are relevant to the participant’s decision to participate. Informed consent is 
documented by means of a written, signed and dated informed consent form.
interim analysis
An interim analysis is an analysis of clinical study data, separated into treatment groups, 
that is conducted before the final reporting database is created/locked.
investigational 
product
A pharmaceutical form of an active ingredient or placebo being tested or used as a 
reference in a clinical trial, including products already on the market when used or 
assembled (formulated or packaged) in a way different from the authorized form, or 
marketed products used for an unauthorized indication, or marketed products used to 
gain further information about the authorized form.

Treatment-emergent adverse event: An untoward medical occurrence that emerges 
during a defined treatment period, having been absent pretreatment, or worsens relative 
to the pretreatment state, and does not necessarily have to have a causal relationship 
with this treatment.
