Primary Outcome Measures :
  1. Change in the Pain Intensity Score to Week 12. [ Time Frame: Baseline; Week 12 ]
    The Pain Intensity Score is the mean value of current pain intensity ratings, obtained twice-daily for 1 week, using an 11-point numerical rating scale where 0 = "no pain" and 10 = "pain as bad as you can imagine". All pain intensity ratings for the primary endpoint will be in reference to the CRPS-affected limb.


Secondary Outcome Measures :
  1. Response to treatment: Proportion of Participants With at Least 30 Percent Reduction in the Pain Intensity Score [ Time Frame: Baseline; Week 12 ]
    Participants with at least a 30 percent decrease in the Pain Intensity Score will be considered to have responded to treatment. The Pain Intensity Score is determined as for the primary endpoint.

  2. Response to treatment: Proportion of Participants With at Least 50 Percent Reduction in the Pain Intensity Score [ Time Frame: Baseline; Week 12 ]
    Participants with at least a 50 percent decrease in the Pain Intensity Score will be considered to have responded to treatment. The Pain Intensity Score is determined as for the primary endpoint.

  3. Change in the Brief Pain Inventory (BPI) Interference Score [ Time Frame: Baseline; Week 12 ]
    The BPI Interference Score is the mean value of 7 self-reported items in question 9 of the BPI Short Form Questionnaire. Participants will rate their interference of pain with general activity, walking, work, sleep and other activities in the past 24 hours, with possible ratings from 0 (does not interfere) to 10 (completely interferes). The BPI interference Score ranges from 0 to 10, with higher values indicating greater pain interference of daily activities.

  4. Patient Global Impression of Change (PGIC) [ Time Frame: Baseline; Week 12 ]
    The PGIC is a self-reported measure of perceived change in overall condition since the start of the study. Participants will select one of seven responses ranging from very much improved to very much worse. A response of very much improved or much improved is generally regarded as a clinically important outcome.

  5. Change in the EuroQol-5 Dimension 5 Level (EQ-5D-5L) Index Score [ Time Frame: Baseline; Week 12 ]
    The EQ-5D-5L Index Score describes the participant's overall health status and is derived from self-reported scores in 5 health dimensions: mobility, self-care, usual activities, pain and discomfort, and anxiety and depression. Participants will rate each dimension at one of 5 levels, with level 1 indicating the best health state (no problems) and level 5 indicating worst health state (e.g., unable to walk about). The EQ-5D-5L Index Score ranges from 0 to 1, with 0 representing death and 1.0 representing perfect health.

  6. Change in the EuroQol Visual Analog Scale (EQ VAS) [ Time Frame: Baseline; Week 12 ]
    The EQ VAS is a self-reported measure of the participant's overall health "today". Participants will place a mark on a 20 cm vertical scale numbered from 0 to 100, with 0 labeled as "the worst health you can imagine" and 100 labeled as "the best health you can imagine". The EQ VAS ranges from 0 to 100, with higher scores representing better overall health.


Other Outcome Measures:
  1. Change in the Worst Pain Intensity [ Time Frame: Baseline; Week 12 ]
    This will be determined as for the primary endpoint, using worst pain intensity ratings. Participants will rate their worst pain intensity during the previous 12 hours twice each day using an 11-point numerical rating scale where 0 = "no pain" and 10 = "pain as bad as you can imagine". Worst pain intensity ratings are in reference to the CRPS-affected limb.

  2. Change in the Average Pain Intensity [ Time Frame: Baseline; Week 12 ]
    This will be determined as for the primary endpoint, using average pain intensity ratings. Participants will rate their average pain intensity during the previous 12 hours twice each day using an 11-point numerical rating scale where 0 = "no pain" and 10 = "pain as bad as you can imagine". Average pain intensity ratings are in reference to the CRPS-affected limb.

  3. Change from Baseline in the Pain Intensity Scores at Each Week [ Time Frame: Baseline to Week 12 ]
    Pain Intensity Scores will be determined as for the primary endpoint using current pain intensity ratings obtained twice-daily. Mean values will be assessed during each of the first 12 weeks of the study.

  4. Response to Treatment: Proportion of Participants with 0 to 100% Decrease in the Pain Intensity Score [ Time Frame: Baseline; Week 12 ]
    Pain Intensity Scores will be determined as for the primary endpoint using current pain intensity ratings obtained twice-daily. Participants will be considered to have responded to treatment using increments of 10% decrease in the Pain Intensity Score, starting from 0% (no decrease in the Pain Intensity Score), 10%, 20%, etc., to 100% (Pain Intensity Score at Week 12 = 0).

  5. Response to Treatment: Proportion of Participants With at Least a 2 Point Decrease in the Pain Intensity Score [ Time Frame: Baseline; Week 12 ]
    Pain Intensity Scores will be determined as for the primary endpoint using current pain intensity ratings obtained twice-daily. Participants will be considered to have responded to treatment if they have at least a 2 point decrease in the Pain Intensity Score.

  6. Change in the Pain Anxiety Symptom Scale (PASS) Total Score [ Time Frame: Baseline; Week 12 ]
    The PASS Total Score is the sum of 20 self-reported items in the PASS Questionnaire. Participants will rate each item in terms of its frequency, ranging from 0 (never) to 5 (always). The PASS Total Score ranges from 0 to 100, with higher scores indicating greater levels of pain-related anxiety.

  7. Change in the Center for Epidemiological Studies Depression (CES-D) Scale Total Score [ Time Frame: Baseline; Week 12 ]
    The CES-D Total Score is the sum of 20 self-reported items comprising symptoms associated with depression. Participants will rate each item in terms of its frequency from "rarely or none of the time (less than 1 day)" to "most or all of the time (5 to 7 days)" during the last week. The CES-D Total Score ranges from 0 to 60, with a score over 21 indicating the possibility of major depression.

  8. Change in Pain Disability Index (PDI) [ Time Frame: Baseline; Week 6; Week 12 ]
    The PDI is the sum of self-reported ratings of disability in 7 categories of activities, including family/home responsibilities, recreation, social activity, self-care, etc. Participants will rate the level of disability that they typically experience due to pain in each of the 7 categories. Ratings are made using a numeric rating scale, with 0 indicating "no disability" and 10 indicating "worst disability". The PDI ranges from 0 to 70, with higher values indicating greater disability due to pain.

  9. Change in the Medical Outcomes Study (MOS) Sleep Scale: Sleep Problems Index [ Time Frame: Baseline; Week 6; Week 12 ]
    The MOS Sleep Scale Sleep Problems Index is derived from participant's responses to questions related to sleep adequacy, sleep disturbance, daytime somnolence, and other aspects of sleep. Participants will respond to 12 questions in the MOS Sleep Scale Questionnaire. Responses are scored, summed and converted to a 0 to 100 scale, with higher scores indicating worse sleep problems.

  10. Change in Pain Medication Score [ Time Frame: Baseline; Week 6; Week 12; Month 6; Month 9; Month 12 ]
    The Pain Medication Score will be derived using the Medication Quantification Scale (MQS III) and is based entirely on information available from the participant's prior and concomitant medications. The MQS III algorithm derives a single numerical value representing the amount of pain medications taken by each participant, taking into account the medication class and dosage.

  11. Change in the Current Pain Intensity in the Extended Follow-up Period [ Time Frame: Baseline; Month 6; Month 9; Month 12 ]
    Participants will rate their current CRPS-related pain intensity at each visit in the extended follow-up period using an 11-point numerical rating scale where 0 = "no pain" and 10 = "pain as bad as you can imagine".

  12. Change in the Average Pain Intensity in the Extended Follow-up Period [ Time Frame: Baseline; Month 6; Month 9; Month 12 ]
    Participants will rate their average CRPS-related pain intensity, recalled over the last 24 hours, at each visit in the extended follow-up period using an 11-point numerical rating scale where 0 = "no pain" and 10 = "pain as bad as you can imagine".

  13. Change in the Worst Pain Intensity in the Extended Follow-up Period [ Time Frame: Baseline; Month 6; Month 9; Month 12 ]
    Participants will rate their worst CRPS-related pain intensity, recalled over the last 24 hours, at each visit in the extended follow-up period using an 11-point numerical rating scale where 0 = "no pain" and 10 = "pain as bad as you can imagine".

  14. Change in the BPI Interference Score in the Extended Follow-up Period [ Time Frame: Baseline; Month 6; Month 9; Month 12 ]
    The BPI Interference Score is the mean value of 7 self-reported items in question 9 of the BPI Short Form Questionnaire. Participants will rate their interference of pain with general activity, walking, work, sleep and other activities in the past 24 hours, with possible ratings from 0 (does not interfere) to 10 (completely interferes). The BPI interference Score ranges from 0 to 10, with higher values indicating greater pain interference of daily activities.

  15. PGIC in the Extended Follow-up Period [ Time Frame: Baseline; Month 6; Month 9; Month 12 ]
    The PGIC is a self-reported measure of perceived change in overall condition since the start of the study. Participants will select one of seven responses ranging from very much improved to very much worse. A response of very much improved or much improved is generally regarded as a clinically important outcome.

  16. Change in the EQ-5D-5L Index Score in the Extended Follow-up Period [ Time Frame: Baseline; Month 6; Month 9; Month 12 ]
    The EQ-5D-5L Index Score describes the participant's overall health status and is derived from self-reported scores in 5 health dimensions: mobility, self-care, usual activities, pain and discomfort, and anxiety and depression.

Participants will place a mark on a 20 cm vertical scale numbered from 0 to 100, with 0 labeled as "the worst health you can imagine" and 100 labeled as "the best health you can imagine". The EQ VAS ranges from 0 to 100, with higher scores representing better overall health.

  18. Change in the Complex Regional Pain Syndrome (CRPS) Severity Score [ Time Frame: Baseline; Week 6; Week 12; Month 6; Month 9; Month 12 ]
    The CRPS Severity Score is the sum of the number of CRPS-related symptoms, reported by the participant over the past 48 hours, and signs, observed by the clinician during a brief examination. Participants are queried for 8 CRPS-related symptoms and assessed for 8 CRPS-related signs, for a score between 0 and 16, with higher scores indicating greater CRPS severity.

  19. Presence or Absence of Complex Regional Pain Syndrome (CRPS) [ Time Frame: Month 6; Month 9; Month 12 ]
    The presence or absence of CRPS will be determined based on CRPS-related signs, assessed by the clinician in a brief examination. Participant reported symptoms for CRPS from the Enrollment Visit will be included with signs applying the CRPS diagnostic criteria ("Budapest clinical criteria"). Participants who meet criteria for CRPS using the diagnostic criteria will be considered as "CRPS present", and those who do not meet the criteria will be considered as "CRPS absent".

  20. Change from Baseline in Bone Turnover Markers [ Time Frame: Baseline to Month 12 ]
    Serum levels of bone formation markers (procollagen type I amino-terminal propeptide and bone alkaline phosphatase) and a bone resorption marker (C-terminal telopeptide of type I collagen) will be determined from blood samples taken during the trial. This information will be used for an exploratory evaluation of bone turnover in response to neridronic acid.
