- Enrolled 23 patients in ACH-4471 Phase 2 C3G six and 12-month clinical trials -
- Targeting end-of-Phase 2 meeting with FDA in fourth quarter of 2019 -
BLUE BELL, Pa., April 03, 2019 (GLOBE NEWSWIRE) -- Achillion Pharmaceuticals, Inc. (Nasdaq: ACHN), a
clinical-stage biopharmaceutical company dedicated to transforming the lives of patients and families affected by
complement-mediated diseases, today announced that it achieved threshold enrollment in the Phase 2 trials of ACH-4471 for patients
with C3 glomerulopathy (C3G), a devastating disease affecting the kidney for which there is no approved therapy. ACH-4471 will be
evaluated in the six-month blinded, placebo-controlled trial (11 patients) and the 12-month open-label trial (12 patients).
“Enrolling our ACH-4471 Phase 2 trials is an important milestone for Achillion, and we would like to thank all
of the patients, families, investigators and participating clinical trial sites for their outstanding contributions,” said Joe
Truitt, President and Chief Executive Officer at Achillion. “The six and 12-month Phase 2 trials for C3G bring us one step closer
to evaluating our first-generation factor D inhibitor in patients who suffer from this chronic disease. We remain on track to
present data from these two Phase 2 trials, along with real-world C3G data, to the U.S. Food and Drug Administration in the fourth
quarter of 2019.”
About the ACH-4471 Phase 2 C3G Trials
The objective of the six and 12-month proof-of-concept trials is to evaluate the safety and efficacy of the oral, small molecule
factor D inhibitor, ACH-4471, in patients diagnosed with C3G. In the six-month trial, patients are blinded and randomized 1:1 to
receive either ACH-4471 or placebo. The 12-month trial is open label. The measures being evaluated include changes in clinical
manifestations of C3G including proteinuria and estimated glomerular filtration rate (eGFR) at the end of the treatment period and
changes in kidney biopsy from baseline.
ACH-4471, Complement Factor D Inhibitor
The Company’s first-generation oral complement factor D inhibitor, ACH-4471, is currently being evaluated for efficacy with Phase 2
clinical programs in both paroxysmal nocturnal hemoglobinuria (PNH) and C3G and has demonstrated preliminary proof-of-concept in
both indications. The PNH program consists of a Phase 2 clinical trial evaluating ACH-4471 in patients who are inadequately
controlled or sub-optimally responding to eculizumab. Additionally, patients continue to dose in the PNH monotherapy extension
trial. The C3G program consists of two Phase 2 clinical trials – a six-month blinded, placebo-controlled trial and a 12-month
open-label trial, described above.

About C3 Glomerulopathy (C3G)
C3G is a devastating disease affecting the kidney for which there is no approved therapy. C3G affects persons of all ages with men
and women equally affected. There are estimated to be approximately 4,000 C3G patients in the United States, 4,000 in Europe, and
1,000 patients with this disease in Japan. C3G describes a rare kidney disease characterized by the presence of C3 protein
fragments in the filtering units (glomeruli) of the kidney. These C3 fragment deposits are thought to be the result of
overactivation of the complement alternative pathway. The chronic deposition of C3 fragments results in inflammation in the
glomeruli (glomerulonephritis) and subsequent permanent kidney damage. An estimated 30 to 50% of C3G patients will require dialysis
and/or a kidney transplant within 10 years of diagnosis.
About Achillion Pharmaceuticals
Achillion Pharmaceuticals, Inc. (Nasdaq: ACHN) is a clinical-stage biopharmaceutical company focused on
advancing its oral small molecule complement inhibitors into late-stage development and commercialization. Research has shown
that an overactive complement system plays a critical role in multiple disease conditions including the therapeutic areas of
nephrology, hematology, ophthalmology and neurology. Achillion is initially focusing its drug development activities on
complement-mediated diseases where there are no approved therapies or where existing therapies are inadequate for patients.
Potential indications being evaluated for its compounds include paroxysmal nocturnal hemoglobinuria (PNH), C3 glomerulopathy (C3G),
and immune complex membranoproliferative glomerulonephritis (IC-MPGN). Each of the product candidates in the Company’s oral small
molecule portfolio was discovered in its laboratories and is wholly owned. To advance its investigational product candidates
into Phase 3 clinical trials and commercialization, the Company plans to work closely with key stakeholders including healthcare
professionals, patients, regulators and payors.
