NOVATO, Calif.

BioMarin Pharmaceutical Inc. (Nasdaq and SWX: BMRN) today announced financial results for its first quarter ended March 31, 2007. The net loss was $9.3 million ($0.10 per share) for the first quarter of 2007, compared to a net loss of $9.8 million ($0.13 per share) for the first quarter of 2006. The net loss during the first quarter of 2007 includes $3.6 million of non-cash stock compensation expense, compared to $1.7 million of non-cash stock compensation expense during the first quarter of 2006.

As of March 31, 2007, BioMarin had cash, cash equivalents, and short-term investments totaling $273.3 million. Including the proceeds from the public offering of senior subordinated convertible notes in April 2007, on a pro- forma basis, BioMarin had cash, cash equivalents, and short term investments totaling approximately $590 million.

"Strong Naglazyme sales are driving better than expected bottom-line results and fueling the development of our pipeline. Based on the upside to first quarter sales, we are increasing our Naglazyme sales expectations for 2007. We are also improving our net loss guidance due to higher interest income and slightly higher Naglazyme sales, partially offset by higher spending on preclinical and clinical development programs, as well as Kuvan launch preparation," said Jean-Jacques Bienaime, Chief Executive Officer of BioMarin.

Mr. Bienaime continued, "We remain on track to submit the NDA for Kuvan by the end of this quarter and, assuming that we receive priority review, anticipate potential approval by the end of the year. We are also pleased that our expanded access program for Kuvan has been approved by the FDA, and physicians and patients representing more than 70 centers in the U.S. have responded with interest, which we believe bodes well for the potential launch of Kuvan. We also remain encouraged regarding the possible application of 6R- BH4 in treating cardiovascular disease and plan to conduct additional studies to further characterize the effect of BH4 in patients with endothelial dysfunction. Additionally, our recent convertible note offering has provided us with the financial flexibility to pursue growth opportunities that will further augment our pipeline and longer-term growth prospects."

Product Sales

Net sales of Naglazyme(R) (galsulfase), an enzyme replacement therapy for mucopolysaccharidosis VI (MPS VI), were $18.4 million for the first quarter of 2007, compared to $16.3 million for the fourth quarter of 2006, representing a sequential increase of approximately 12.9 percent. Naglazyme net sales for the three months ended March 31, 2006 were $7.0 million. BioMarin is commercializing Naglazyme in the United States, Europe, and Latin America, and through distributors in other international markets.

Net sales of Aldurazyme(R) (laronidase), an enzyme replacement therapy for mucopolysaccharidosis I, (MPS I) by BioMarin/Genzyme LLC increased by approximately 25.8 percent to $26.8 million for the first quarter of 2007, compared to $21.3 million in the first quarter of 2006. Aldurazyme net sales for the three months ended December 31, 2006 were $26.5 million. BioMarin's share of the profit of BioMarin/Genzyme LLC was $6.2 million for the first quarter of 2007, compared to a profit of $3.8 million for the first quarter of 2006.

Royalty and License Revenues

Royalty and license revenues for the first quarter of 2007 were $0.4 million, and include royalties on net product sales of the Orapred product line, including Orapred(R) (prednisolone sodium phosphate oral solution) and Orapred ODT(TM) (prednisolone sodium phosphate orally disintegrating tablets). BioMarin expects to receive an additional milestone payment of $4.0 million on the first anniversary of FDA approval of Orapred ODT in June 2007.

  Updated Financial Guidance

  2007 Projected Net Product Sales

BioMarin estimates 2007 net sales of Naglazyme to be in the range of $76 million to $82 million from a previous range of $74 million to $78 million and 2007 sales of Aldurazyme by the joint venture to be in a range of $115 million to $125 million.

2007 Projected Net Loss

BioMarin estimates its GAAP net loss for the fiscal year ending December 31, 2007 to be in the range of $18 million to $23 million from a previous range of $20 million to $25 million. This includes approximately $16 million to $18 million in non-cash stock compensation expense. Additionally, the 2007 projected net loss includes the $4 million Orapred ODT milestone payment and a $15 million milestone payment from Merck Serono in the second half of 2007 for the acceptance of the MAA filing for Kuvan.

Update on 6R-BH4 Program for Cardiovascular Indications

Post-hoc sub-group analyses of the Phase 2 trial for uncontrolled hypertension revealed a greater effect of BH4 in patients with higher systolic blood pressure of >150 mm Hg than in patients with systolic blood pressure <150 mm Hg, with a within group p-value of 0.004. The placebo group did not show a difference when comparing placebo patients with greater or less than 150 mm Hg in systolic blood pressure. When comparing 6R-BH4 to placebo in patients with a mean systolic blood pressure of >150 mm Hg, the BH4 group had a mean systolic blood pressure reduction of 14.1 mm Hg, compared to a mean systolic blood pressure reduction of 5.9 mm Hg in the placebo group, a difference of 8.2 mm Hg that did not reach statistical significance with a p- value trend of 0.142. These are post-hoc analyses and can only help provide insights that will need to be confirmed in prospectively designed studies. In an effort to better understand the role of BH4 in treating endothelial dysfunction and cardiovascular disease, BioMarin plans to initiate two small exploratory studies in the second half of 2007:

  *  A double-blind placebo-controlled study to assess the effect of 6R-BH4
     on endothelial dysfunction in approximately 40 subjects with more
     severe systolic hypertension (SBP >145 mm Hg) and with confirmed and
     significantly impaired endothelial function.
  *  A clinical study to assess the effect of co-administration of Vitamin C
     with 6R-BH4 on 6R-BH4 pharmacokinetics and efficacy in treating
     endothelial dysfunction in approximately 40 subjects with more severe
     hypertension (SBP >150 mm Hg) and significantly impaired endothelial
     function.  Vitamin C can have a direct oxidation protective effect on
     BH4, and the level of Vitamin C in the formulation from the prior
     hypertension study was much higher than in the current 6R-BH4
     formulation.  We will assess whether this protective effect is
     meaningful in patients with cardiovascular disease.

After reviewing the results of the hypertension study in greater detail, a few additions have been made to the protocol for the ongoing Phase 2 trial for peripheral arterial disease. Measures of endothelial dysfunction and oxidative stress will be added to the protocol at several sites, and given the potential that increased Vitamin C might protect BH4 from oxidation in patients, co-administration of Vitamin C with BH4 or placebo will be added to half of the patients in the study.

A Phase 2 trial for sickle cell disease and an investigator-sponsored trial for pulmonary arterial hypertension are both expected to begin in the second quarter of 2007.

Update on Phenylase Program

Preclinical data demonstrates that Phenylase administered subcutaneously once weekly in PKU mice resulted in a sustained decrease in blood Phe to levels within a normal range for a 12-week period. BioMarin plans to file an IND by the end of 2007 and to be in the clinic in early 2008.

  Anticipated Upcoming Milestones

  *  Q207 -- NDA filing for Kuvan
  *  Q207 -- Initiation of Phase 2 Trial of 6R-BH4 in sickle cell disease
  *  Q207 -- Initiation of investigator-sponsored trial of 6R-BH4 in
     pulmonary arterial hypertension
  *  June 2007 -- Initiation of Expanded Access Program for Kuvan for
     approximately 500 PKU patients in the U.S.
  *  Q307 -- MAA filing for Kuvan by Merck Serono
  *  Q407 -- IND filing for Phenylase
