Debrief: Patient-Focused Drug Development for Neuropathic Pain Associated with Peripheral Neuropathy

PFDD

Opening Remarks

Pamela Horn, MD Medical Officer Team Lead, DAAAP, CDER, FDA

  • Meeting addresses an unmet need for treatment that is finding patient-centered endpoints for clinical trials.
  • Hearing from patients will help steer drug development
  • FDA works to ensure safety, effectiveness, and quality of drugs

Overview of FDA’s Patient-Focused Drug Development Initiative

Sara Eggers, PhD OSP, CDER, FDA

  • Goal is to make more systematic way to gether patients inputs and perspectives
  • Originated from PDUFA V
  • This meeting is the 19th of 24 PFDD meetings for FY 2013-2017
  • Active patient involvement and participation encouraged

Background on Pain Neuropathies and Available Treatments

Steven Galati, MD, Medical Officer, DAAAP, CDER, FDA

  • Chronic Pain can be nociceptive (injury/inflammation) or neuropathic (pain without a stimulus)
  • Many different causes of neuropathy including diabetes and medical treatment
  • For the FDA to approve a neuropathy drug, there must be at least two successful trials
  • The FDA wants to know what symptoms bother patients the most so companies can target them in trials
  • Some challenges to drug development are that patients are still not satisfied with the drug and that one medication cannot cover multiple types of neuropathy

The Road from PFDD Meetings to Clinical Trial Endpoints

Nikunj Patel, PharmD Clinical Outcomes Assessments Staff, CDER, FDA

  • Patient recorded outcomes (such as answers to a questionnaire) will help create clinical trial endpoints
  • Stakeholders can listen to patients’ perspectives
  • PFDD meetings ensure that PRO’s accurately describe efficacy and drug safety
  • FDA encourages audience to engage others outside of PFDD meetings for more input
  • 3 pathways to generate outcome assessments
    • Input during investigational new drug submissions
    • Clinical outcome assessments (COA’s) to prove a treatment’s benefit during trials
    • Critical Path Innovation Meetings to advance drug efficacy using input from industry, academia, and patient-related groups

Panel #1 Discussion on Topic 1: Disease Symptoms and Daily Impacts

Adam Halper

    • Symptoms including soreness/muscle heaviness vary in intensity based on how much activity he does
    • Other symptoms including burning sensations are not “activity-dependent”
    • Limited mobility and cannot stand for more than 10-30 minutes
    • On worst days, can walk for only 5 minutes and cannot sleep comfortably
    • On best days, can walk about 3 miles
    • Intensity of symptoms fluctuates (no clear progression)

Susan Waldrop

    • Condition resulted from chemotherapy for colon cancer
    • Experiences burning sensations in limbs, electric shocks, and cannot walk, unpleasant numbness, increased sensitivity to cold
    • She cannot feel feet, causing problems with balance
    • Good days of normal activity are followed by bad nights

David Morrow (VP, Neuropathy Support Network)

    • Also resulted from chemotherapy for colon cancer
    • Slow progression
    • Experiences some foot and hand numbness, stabbing pains in feet, balance problems
    • Symptoms became less noticeable over time

Beth Lannon

    • Began as bilateral pain and slowly progressed
    • Sharp, constant pain (“like a hammer to my feet”), electrical shocks
    • Symptoms worsen with activity
      • Cannot sit for more than 15 minutes

Panel #2 Discussion on Topic #2: Current Approaches to Treatment

Linda Spinella

    • Pain because of multiple herniated disks
    • Was prescribed Lyrica, OTC pain relievers (incl. Tylenol), Prednisolone, opiods
    • Also went to the chiropractor and received epidurals for short-term relief
    • Cannot sleep without medication
    • Usually anxious, jittery, agitated

Cherie Pagett

    • Experiences numbness up to her knees
    • Takes Neurontin, Miradol, Lidocaine, opioids
    • When she took Lyrica, she gained 25 pounds in six weeks
    • Does not feel that her pain is under control because she will have intense flashes of pain

Louis Schmitt

    • 20 months of high dosage of IVIG to repair damaged nerves
    • Believes meditation managed anxiety/depression associated with his neuropathy
    • Prescribed 4000 mg neurontin but it did not work
    • Feels that 450 mg Lyrica is a “life saver” because it gives almost immediate relief
    • Tries to exercise as often as he can
    • Brain feels lagged (“mental fog”),
    • Experiences drowsiness, weight fluctuations, and swelling
    • If he were in a clinical trial, he would like to know of all side effects ahead of time and any estimate of effectiveness

Jackie Evangelista

    • Neuropathy caused by lyme disease
    • Slow progression of disease to the point that she cannot notice the worsening f some symptoms
    • Condition has not improved that much from medication
      • Feels treatment “only takes the edge off… does not stop advance”

Large-Group Facilitated Discussion: Topic 2

  • Trials should measure how much time one can do a specific physical task
  • Some patients feel that just pain relief is not the best indicator for drug effectiveness
  • Patients usually try a treatment for 3-4 weeks before deciding if it works
  • The issue of side effects is the most prevalent causing of switching medications/therapies
  • Some patients feel that support groups, meditation, and other activities to boost emotional well being help diminish the effect of pain

Addressing Statin Intolerance

STATIN INTOLERANCE 

 

High LDL-C (low-density lipoprotein – cholesterol or hypercholesterolemia) is a significant risk factor for cardiovascular disease. The CDC (Centers for Disease Control) through NHANES (National Health & Nutrition Examination Survey) estimated that over 81 million U.S. adults have elevated levels of LDL-C. In the U.S., increasing attention has been placed on aggressive LDL-C lowering.

This has led to the combination of statins with other treatments to reach LDL-C goals. Statins which includes such brand names as Lipitor, Zocor, Pravachol, Crestor, Livalo and others have been shown to be effective in reducing LDL-C and consistently have been shown to be associated in reduction in heart and vascular disease risk. The most common side effects of statins include gastrointestinal intolerance such as constipation, nausea, or indigestion, headache and upper respiratory type symptoms.

However, a subset of patients is unable to tolerate statins due to side effects, including muscle pain or weakness (Myalgia), increased glucose levels and increased liver transaminase.  In 2012, the FDA warned that statins can cause hyperglycemia (an increase in blood sugar levels) and increased the risk of worsening of glycemic control and of new onset diabetes.

Non-statin-cholesterol-medication

A new class of cholesterol drug could sharply cut bad LDL cholesterol in people who cannot tolerate the commonly used cholesterol-lowering medications called statins.

Praluent (alirocumab injection) and Repatha (evolocumab injection) are PCSK9 (proprotein convertase subtilisin/kexin type 9) inhibitors. PCSK9 inhibitors work by blocking a protein in the liver that helps regulate LDL. These drugs are for use in addition to diet and maximally tolerated statin therapy in adult patients with heterozygous familial hypercholesterolemia (HeFH) or patients with clinical atherosclerotic cardiovascular disease such as heart attacks or strokes, who require additional lowering of LDL cholesterol. HeFH is an inherited condition that causes high levels of LDL cholesterol.

Kynamro (mipomersen sodium injection) is a first-in-class antisense oligonucleotide (ASO) inhibitor targeted to apolipoprotein B-100 (apoB-100). Mipomersen’s proposed indication is as an adjunct to maximally tolerated lipid-lowering medications and diet to reduce low-density lipoprotein (LDL-C), apoB, total cholesterol, non-high-density-lipoprotein-cholesterol (non-HDL) and lipoprotein (a) in individuals with homozygous familial hypercholesterolemia (HoFH). HoFH is an inherited condition occurs when the body is unable to remove LDL-C from the blood causing abnormally high levels of circulating LDL-C.

Juxtapaid (lomitapide capsule) is a new medication approved for lowering cholesterol. It is approved for use only in patients with familial hypercholesterolemia already on statin mediations. Those are patients with extreme elevations in LDL cholesterol and high risk of early heart disease. It is not a statin, and is the first in a new class of medications called microsomal triglyceride transfer protein (MTP) inhibitors. Juxtapid is an adjunct to a low-fat diet and other lipid-lowering treatments, including LDL apheresis where available, to reduce LDL-C, total cholesterol (TC), apolipoprotein B (apo B) and non- high-density-lipoprotein cholesterol (non-HDL) in patients with homozygous familial hypercholesterolemia (HoFH).

REG. PATHWAY: Priority Review, Orphan Drug Designation, Classificaiton: Radioactive diagnostic agent

DEVICE DESCRIPTION:

  • Sterile, single-dose kit for preparation of Ga 68 dotatate injection for intravenous use
  • Uptake of Ga 68 dotatate reflects the level of somatostatin receptor density in NETs
  • Uptake can  be seen in other tumor types, other pathologic conditions, normal variant
  • Uptake of Ga 68 dotatate may need to be confirmed by histopathology

EFFECTIVENESS:

  • Three studies
  • Study 1: Comparison of Ga 68 dotatate images of NETs to images obtained with approved drug, then confirmed with computed tomography (CT) and/ or magnetic resonance imaging (MRI)
  • Study 2: Evaluation of Ga 68 dotatate images using histopathology or clinical follow up as reference standards
  • Study 3: Evaluation of patients with NET recurrence using Ga 68 dotatate images
  • Results confirmed usefulness of Ga 68 dotatate images in finding neuroendocrine tumor location .

SAFETY

  • Contributes to overall long-term cumulative radiation exposure
  • Patients should drink and urinate as often as possible during the first hours following administration to help reduce this risk
  • No serious adverse reactions

APDS.JPG

SUMMARY

  • FDA is helping advance the development of an artificial pancreas device system (APDS)—an innovative device that automatically monitors blood glucose and provides appropriate insulin doses in people with diabetes who use insulin
  • Forward looking Guidance issued – prior to any approved device – to encourage development
  • Recommendations on appropriate endpoints and evidentiary standards for PMA approval; pediatric development encouraged
  • Manufacturers need to also focus on Quality System: Software (including sensors) and Hardware. Software problems anticipated. Require design features to prevent malfunctioning of system.
  • Cybersecurity concerns need to be addressed.
  • Interoperability issues need to be addressed
  • Regulatory burden for new technology depends on scope
  • Encourage Pre-Submission Meeting to align on required studies and study design to meet Intended Use/Indication for Use. Identify patient population, appropriate software algorithm for dosing for designing trial
  • Medtronic has completed pivotal trial with APDS and FDA submission anticipated
