The Medicines Company Announces Positive Results for Solo II Trial of 
Oritavancin in the Treatment of Acute Bacterial Skin and Skin
Structure Infections (ABSSSI) 
SOLO II Trial Meets All Protocol-Specified Endpoints Comparing
Oritavancin, Given as One Single Dose, to Vancomycin Given
Twice-Daily for 7-10 Days Intravenously; Combined SOLO I and SOLO II
Findings in MRSA Infections Show Higher Proportion of Oritavancin
Patients Achieved at Least 20% Reduction of Lesion Area at 48-72
Hours 
PARSIPPANY, NJ -- (Marketwired) -- 07/02/13 --  The Medicines Company
(NASDAQ: MDCO) today announced results for its Phase 3 SOLO clinical
trial program of oritavancin, which is under investigation for the
treatment of acute bacterial skin and skin structure infections
(ABSSSI) caused by susceptible gram-positive bacteria, including
methicillin-resistant Staphylococcus aureus (MRSA). SOLO I and SOLO
II are identical multicenter, double-blind, randomized clinical
trials. The Company reported positive SOLO I results in December 2012
and report similar positive SOLO II results today. 
In SOLO II, all protocol-specified primary and secondary efficacy
endpoints were met. SOLO II demonstrated oritavancin to be
non-inferior to vancomycin for both US and European regulators'
required efficacy endpoints. All pre-specified endpoints were
achieved, both for the Early Clinical Evaluation (ECE) (or 48-72
hour) required by the US Food and Drug Administration (FDA) and for
the later Post Therapy Evaluation (PTE) (7-14 days after end of
treatment) required by the European Medicines Agency (EMA). In SOLO
II, adverse events were reported with similar frequencies on
oritavancin and vancomycin. 
The combined SOLO trial data demonstrated that oritavancin and
vancomycin efficacy were similar for the ECE and PTE endpoints.
However, in microbiologically confirmed MRSA patients, the target
population for such therapies, oritavancin-treated patients achieved
the FDA-proposed endpoint of greater than or equal to 20% reduction
of lesion area at ECE more frequently than vancomycin-treated
patients. Under the Special Protocol Assessment (SPA) agreed with the
FDA, the protocols pre-specified that MRSA patients from the SOLO
studies would be pooled for the evaluation of efficacy.  
Commenting on the results, Clive Meanwell MD PhD, Chairman and Chief
Executive Officer of The Medicines Company said: "SOLO trial data
consistently show that a single dose of oritavancin given on
presentation of a patient with ABSSSI to hospital can cure gram
positive infections, including MRSA infections, and be at least as
efficacious as multiple days of twice-daily vancomycin infusions. The
safety profile also appears potentially advantageous over vancomycin.
We anticipate submitting an application for oritavancin US market
clearance in the fourth quarter of 2013 and a European filing in
2014." 
The combined SOLO studies represent the largest patient population
(1,987 patients in intent-to -treat population) evaluating an
anti-infective for the treatment of ABSSSI in controlled clinical
trials and have assessed one of the largest subsets of patients with
documented MRSA infection (405 patients).  
"The SOLO clinical trials are compelling due to the size of the
program, the range of severe skin infection patients enrolled and the
powerful and innovative drugs studied," said Ralph Corey MD,
Professor of Medicine and Infectious Disease at Duke University and
Principal Investigator of the SOLO Trials. "Given the high rate of
efficacy the vancomycin comparator demonstrated in this and other
similar trials, the most compelling finding in SOLO is in the
pre-specified pooled findings that more oritavancin-treated MRSA
patients had a greater than or equal to 20% reduction in their skin
lesion up to 48 to 72 hours after treatment initiation. The benefit
of an early, definitive and aggressive treatment strategy in
seriously infected patients warrants additional study in skin and
other severe infections, including those requiring prolonged periods
of treatment."

Safety profiles, measured at any point up to 60 days after treatment,
were similar across treatment groups in SOLO II. Overall, 50.9% of
patients on oritavancin and 50.2% of patients on vancomycin were
reported to experience at least one adverse event. In SOLO II,
treatment emergent adverse events considered by investigators as
related to study drug were reported by similar proportions of
patients treated with oritavancin and vancomycin (21.7% and 25.5%,
respectively).

*p value=0.032 
When the SOLO I and SOLO II studies are combined, the safety profiles
were similar across treatment groups (safety population: 976 in
oritavancin, 983 in vancomycin). Overall, 55.3% of patients on
oritavancin and 56.9% of patients on vancomycin were reported to
experience at least one adverse event. Fewer treatment emergent
adverse events considered by investigators as related to study drug
were reported among patients treated with oritavancin than vancomycin
(22.2% vs. 28.4% p=0.002). Proportions of patients with adverse
events leading to study drug discontinuation were low and comparable
between oritavancin and vancomycin (3.7% and 4.2%, respectively).  
The design of the Phase 3 SOLO clinical trial program was agreed to
through the SPA process with the FDA and was also reviewed formally
by the EMA. The pivotal Phase 3 trials are designed to support the
filing of a New Drug Application in the United States as well as a
Marketing Authorization Application in Europe.
