Inclusion Criteria

1. The subject voluntarily provides informed consent to participate in the
study.
2. The subject participated in study TDE-PH-310 and met the definition of
clinical worsening (as specified in Protocol TDE PH 310), remained on study
drug, was compliant with study procedures and assessments during the TDE-PH-310
Study or was currently enrolled in that study at the time the study was
discontinued by the sponsor.
3. All WOCBP must practice true abstinence from intercourse when it is in line
with their preferred and usual lifestyle, or use 2 different forms of highly

after discontinuing study medication. Medically acceptable forms of effective
contraception include: (1) approved hormonal contraceptives (such as birth
control pills), (2) barrier methods (such as a condom or diaphragm) used with a
spermicide, (3) an intrauterine device or (4) partner vasectomy. For women of
childbearing potential, a negative urine pregnancy test is required at Baseline
(study entry) prior to initiating study medication. WOCBP includes any female
who has experienced menarche and who has not undergone successful surgical
sterilization (hysterectomy, bilateral tubal ligation, or bilateral
oophorectomy) or is not postmenopausal [defined as amenorrhea for at least 12
consecutive months].

3. The subject was prematurely discontinued from study TDE-PH-310 for reasons
other than a clinical worsening event.
4. The subject developed a concurrent illness or condition during the conduct
of TDE PH 310 which, in the opinion of the Investigator, would represent a risk
to overall health if they enrolled in this study.
