Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of the study is to evaluate whether the DIA/NPR-6 is a better pain reliever in patients with diabetic neuropathic pain of the feet compared to placebo.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Subjects will be enrolled in the study for a maximum of 63 days, including an optional 14-day screening period, 42 days of active product administration, and followed by post-treatment blood work, EKG, and questionnaires within 24-hours following study treatment completion and a psychiatric and primary health care provider evaluation within 1 week of trial completion.

The primary objective of this study is:

* To evaluate the impact of PGP-010-50-1 on subject's painful diabetic neuropathic pain (pDNP), anxiety, and sleep quality compared to a placebo control.
* To evaluate the impact of PGP-010-50-1 on the subject's impression of their response to the treatment compared to a placebo control.

The secondary objectives of this study are:

* To evaluate the safety of PGP-010-50-1 for the treatment of painful diabetic peripheral neuropathy (DPN) of the feet compared to a placebo control
* To evaluate PGP-010-50-1 on liver function.
* To evaluate PGP-010-50-1 on Hbg A1C
