Evaluation of Intravesical LP08 in Patients With Interstitial Cystitis/Painful Bladder Syndrome

This is a single-center, dose-ranging, placebo-controlled, double-blind, randomized study
including male and female subjects with interstitial cystitis/bladder pain syndrome (IC/BPS)
as determined by a physician using the current diagnostic criteria for IC/BPS. A total of 36
subjects will be enrolled at up to five (5) study sites in the U.S. Enrollment is expected to
be completed within one year of initiating the study. The study is comprised of two parts.
The first part of the study is a dose-ranging, randomized, double-blind, placebo-controlled
study evaluating the safety, tolerability and efficacy of LP-08 at 20 mg and 80 mg doses as
compared with placebo. The second part of the study is an Open Label Extension study of the
safety, tolerability and efficacy of LP-08 80 mg. Subjects randomized to the placebo control
group must have completed the randomized portion study, including the eight week follow-up
period, to be eligible for the Open Label Extension.

Inclusion Criteria:

A patient is deemed suitable for inclusion in the study if the patient meets the following
criteria:

1. Male or female at least 18 years of age

2. IC/BPS diagnosed by a health care provider based the following criteria:

Complaint of suprapubic pain related to bladder filling, accompanied by other symptoms
such as increased daytime and night time frequency, in the absence of proven urinary
infection or other obvious pathology Have had IC/BPS symptoms for at least six months
Score of ≥ 12 on the ICSI/PI at baseline Urinary frequency > 10 times a day by
self-report and confirmed on baseline three-day voiding diary Have IC/BPS that in the
judgment of the investigator has been stable in the previous 30 days IC/BPS-related
pain defined as a score of > 3 cm and < 9 cm on the pain VAS where 0 is no pain and 10
is maximum pain

3. Have had inadequate clinical responses with conservative treatments, which may include
one or more of the following: 1) timed voiding and behavioral modification therapy, 2)
dietary restrictions, 3) stress reduction and/or 5) oral therapy with any of the
following medications:

Antidepressants Antihistamines Antimuscarinic and anticholinergic agents Alpha
adrenergic blockers Analgesics Pentosan polysulfate

4. Women of childbearing potential: have a negative urine pregnancy test at screening,
and must agree to use an acceptable from of contraception (oral contraceptives,
intrauterine or double barrier methods), as agreed to by the investigator, during the
study period

5. Provide signed informed consent

6. Subject agrees to be available for the follow-up evaluations as required by the
protocol

Exclusion Criteria:

Patients are excluded from enrollment in the study if any of the following are true:

1. Currently pregnant or breastfeeding, or plan to become pregnant during the course of
the study

2. Have received investigational products or devices within 30 days prior to screening
visit

3. Have received intravesical therapy or bladder hydrodistention within 30 days prior to
screening visit. Intravesical instillations may include liquid or drug delivery
devices, pentosan polysulfate sodium, lidocaine, steroid, heparin, chondroitin and any
combination or additional formulation.

4. Have participated in IC/BPS research trial within 90 days prior to screening visit or
has not returned to baseline if participated in IC/BPS research trial greater than 90
days prior to screening visit

5. Have received any of the following medication within 30 days of screening visit,
unless such medications have been administered at a stable dose during this month and
are expected to remain at a stable dose throughout the study:

Antidepressants Antihistamines (use of antihistamines as needed for allergies is
allowed) Anticonvulsants Antimuscarinic and anticholinergic agents Alpha adrenergic
blockers Pentosan polysulfate sodium Oral chondroitin

6. Have indicated use of > 70 mg of morphine equivalents of opioids per week to control
their IC/BPS pain within 30 days prior to screening, or are expected to require this
level of IC/BPS pain control during the study period

7. Previous augmentation cystoplasty, cystectomy, neurectomy (i.e., hypogastric nerve
plexus ablation). Bladder botulinum toxin injections within nine months prior to
screening.

8. Sacral and/or pudendal nerve neuromodulation device (Interstim) within the last 6
months. Subjects would not be excluded if they had Interstim greater than 6 months ago
and is on a stable setting within the past 90 days

9. Percutaneous Tibial Nerve Stimulation (PTNS) treatment within the past 90 days

10. Evidence of renal impairment (creatinine > two times the upper limit of normal at
Visit 1), hepatic impairment (AST or ALT > three times the upper limit of normal at
Visit 1), clinically significant cardiovascular, respiratory, or psychiatric diseases
per investigator's judgment

11. Post-void residual (PVR) urine volume of > 150 mL at screening

12. Any condition that in the judgment of the investigator would interfere with the
patient's ability to provide informed consent, comply with study instructions, place
the patient at increased risk, or which might confound the interpretation of the study
results

13. Previously received intravesical liposomes

14. Urinary tract or prostatic infection in the past 90 days before study entry

15. Active genital herpes or vaginitis

16. Urethral diverticulum

17. Pelvic malignancy within the past five years

18. History of cyclophosphamide or chemical cystitis, or tuberculosis or pelvic radiation

19. History of bladder or prostate tumors (benign or malignant)

20. Uncontrolled diabetes

21. Has any condition that would preclude treatment due to contraindications and/or
warnings in the product labeling
