                                                                    Exhibit 99.1

         Discovery Laboratories Reports First Quarter Financial Results

Doylestown, PA -- May 14, 2003 -- Discovery Laboratories, Inc. (Nasdaq: DSCO), a
late-stage specialty biopharmaceutical company developing its proprietary
surfactant technology as Surfactant Replacement Therapies for respiratory
diseases, today announced financial results for the first quarter of 2003.

For the quarter ended March 31, 2003, the Company reported a net loss of $4.5
million, or $0.14 per share, on approximately 32.9 million weighted average
common shares outstanding, compared to a net loss of $3.37 million, or $0.13 per
share, on approximately 25.8 million weighted average common shares outstanding
for the same period in 2002.

The increase in the net loss primarily reflects clinical trial costs incurred
for the Company's lead product, Surfaxin(R) (which is currently in three Phase 3
trials and two Phase 2 trials for critical care patients with life threatening
respiratory disorders), as well as activities related to the development of the
Company's inhalable aerosol surfactant programs to potentially treat a variety
of respiratory conditions. The results also include a charge of $198,000 for
pre-launch commercialization activities for Surfaxin for which funding has been
provided by a secured, revolving credit facility pursuant to a collaboration
arrangement with Quintiles Transnational Corp. ("Quintiles").

The increase in the weighted average number of shares outstanding is primarily
due to approximately 822,000 common shares issued in connection with the March
2002 expansion of the strategic alliance with Laboratorios del Dr. Esteve
("Esteve") and approximately 6.4 million common shares issued to selected
institutional and accredited investors in a private offering in November 2002.
As of March 31, 2003 and March 31, 2002, there were approximately 32.9 million
and 26.4 million common shares issued and outstanding, respectively.

As of March 31, 2003, the Company had cash and investments of approximately
$14.2 million. In addition the Company has a secured revolving credit facility
of $8.5 million to $10.0 million with Quintiles. The Company may use this credit
facility for general working capital purposes but is obligated to use a majority
of the funds borrowed under this facility for pre-launch marketing of Surfaxin.
This credit facility is available for use through December 10, 2004, and monies
become available in three tranches upon satisfying certain conditions. We have
satisfied the conditions for availability of the first two tranches and as of
March 31, 2003, $5.7 million was available for borrowing and $1.65 million was
outstanding under the credit facility. The Company has a capital lease financing
arrangement with the Life Science and Technology Finance Division of General
Electric Capital Corporation that provides, subject to certain conditions, for
up to $1.0 million in financing for capital purchases. As of March 31, 2003, the
Company has used approximately $475,000 of this financing arrangement. Our
currently available financial resources will be adequate to satisfy our capital
needs into the second quarter of 2004.

Robert J. Capetola, Ph.D., President and Chief Executive Officer of Discovery
stated, "Surfactant Replacement Therapies have the potential to treat several
respiratory diseases or to prevent

respiratory conditions from becoming severe, even life-threatening, events. We are the only company with a humanized surfactant technology platform that can be developed into a pipeline of Surfactant Replacement Therapies tailored for specific respiratory conditions. Our lead product, Surfaxin (a liquid instillate), is in three Phase 3 and two Phase 2 clinical trials for critical care patients suffering from various Respiratory Distress Syndromes. Discovery has recently expanded its product pipeline to include inhalable aerosol surfactant formulations and we are positioned to enter Phase 1b/2a clinical trials for asthma and Acute Lung Injury. We remain focused on executing the critical operational and clinical milestones necessary to build a meaningful specialty biopharmaceutical company that has the potential to bring groundbreaking respiratory therapies to patients with limited or no effective treatments currently available." Selected updates on the Company's progress in the first quarter: o Pivotal, Multinational Landmark Phase 3 Clinical Trial for Respiratory Distress Syndrome (RDS) in Premature Infants - This trial is intended to provide the basis for New Drug Applications with the FDA and other worldwide regulatory authorities. The Company's existing base of 50 qualified clinical sites are enrolling and treating patients in a manner that is consistent with the expectation that this trial will be completed and data announced early in the fourth quarter of 2003. o Supportive Phase 3 RDS Trial - The Company is currently conducting a supportive multinational Phase 3 trial (referred to as the KL4-IRDS-02 Trial) to demonstrate the safety and non-inferiority of Surfaxin compared to Curosurf(R), an approved porcine lung extract, for the treatment of Respiratory Distress Syndrome in premature infants. The Company is evaluating whether to conclude this trial early to conserve financial resources and reallocate clinical resources to its pivotal Phase 3 trial. o Part B, Phase 2 Clinical Trial for Acute Respiratory Distress Syndrome in Adults (ARDS) - Enrollment for this trial is expected to be completed in the fourth quarter of 2003. Akorn, Inc., the Company's contract manufacturer for Surfaxin for this trial, informed us previously that certain operating difficulties experienced in one of its production rooms, primarily used for the filling of sterile pharmaceuticals, had been rectified and that the room had been returned to operational status. Manufacturing activities for Surfaxin for our ARDS trial recommenced in March 2003 and certain filling-related processes, solely related to Akorn's sterile filling room, needed additional attention. These issues have been addressed to the satisfaction of the Company's manufacturing personnel and the Company believes that Akorn will be on schedule to recommence Surfaxin manufacture for this trial by the end of May 2003. o Surfaxin Manufacturing - In light of the late stage development status of Surfaxin, the ongoing implementation of the Company's commercialization strategy, and in preparation for its inhalable aerosol clinical programs, the Company is evaluating several additional contract manufacturing sites and investing in manufacturing scale-up and enhancements, including equipment. The Company expects to select its second 5

contract manufacturer in the second quarter of 2003 and have this additional manufacturing capability operational by the fourth quarter of 2003. o Inhalable Aerosol Surfactant Formulations - The Company aerosolized its humanized lung surfactant as an inhalable liquid formulation that retained the essential pharmacological properties of a functioning surfactant (i.e., the surface-tension lowering ability necessary to restore lung function and keep airways open and expanded) and could achieve delivery rates necessary for therapeutic dosing in an appropriate time period. The Company believes that Surfactant Replacement Therapy for respiratory medicine has now evolved to where aerosol formulations of engineered lung surfactant have the potential to be developed to treat a broad range of respiratory diseases. o SARS and Surfactant Replacement Therapies - On Wednesday, May 7, 2003, Dr. Robert J. Capetola testified before the House Committee on Energy and Commerce Subcommittee on Oversight and Investigations regarding the possible application of the Company's Surfactant Replacement Therapy programs to address Severe Acute Respiratory Syndrome (SARS). SARS is an acute respiratory illness in which patients have difficulty breathing. Dr. Capetola informed the Committee that Surfactant Replacement Therapy has the potential to play an important role in addressing the SARS crisis because it is intended to maintain or restore proper lung function. If the necessary activities, parties and adequate resources could be properly organized, Surfactant Replacement Therapy could be evaluated for the most severe SARS patients on mechanical ventilation as early as mid-to-late-summer of 2003, and inhalable surfactant aerosol formulations could be evaluated for maintaining lung function in SARS patients by fall of 2003. o Anti-Inflammatory Properties - Research at the University of Pennsylvania Department of Medicine, Pulmonary, Allergy and Critical Care Division established that Discovery's humanized lung surfactant, including Surfaxin, exhibits significant anti-inflammatory properties in the lungs. Many respiratory diseases, such as Acute Respiratory Distress Syndrome, Acute Lung Injury, asthma, and chronic obstructive pulmonary disease (COPD), are associated with an inflammatory event and degradation of natural lung surfactant. About Discovery Laboratories Discovery Laboratories, Inc. is a specialty biopharmaceutical company developing its proprietary surfactant technology as Surfactant Replacement Therapies for respiratory diseases including Respiratory Distress Syndromes, Acute Lung Injury (ALI), asthma, Chronic Obstructive Pulmonary Disease (COPD), and upper airway disorders. Discovery's surfactant technology produces an engineered version of natural human lung surfactant that is designed to precisely mimic the essential properties of human lung surfactant. Discovery believes that through its surfactant technology, pulmonary surfactants have the potential, for the first time, to be developed into a series of respiratory therapies for hospitalized and ambulatory patients. Surfaxin, Discovery's lead product, is in three Phase 3 and two Phase 2 clinical trials for critical care patients with life-threatening respiratory disorders where there are few or no approved therapies available. Discovery's first aerosol surfactant product is positioned to enter clinical trials for hospital patients with severe asthma 6

or acute lung injury. Discovery has a commercialization alliance with Quintiles Transnational Corp. and a strategic alliance with Laboratorios del Dr. Esteve S.A.
