Aradigm Corporation (NASDAQ: ARDM) (the “Company”) today announced financial results for the first quarter and three months ended March 31, 2018.

First Quarter 2018 Financial Results

The Company recorded $1.5 million in revenue in the first quarter of 2018 compared with $1.7 million in revenue in the first quarter of 2017. The Company recognized $1.3 million in contract revenue – related party, $29,000 in government contract revenue and $129,000 in government grant revenue for the first quarter of 2018, as compared to $1.6 million in contract revenue – related party, $39,000 in government contract revenue and $31,000 in government grant revenue for the first quarter of 2017.

Total operating expenses for the first quarter of 2018 were $5.3 million, compared with total operating expenses of $4.5 million for the first quarter of 2017. The increase in expenses was related to the FDA Advisory Committee Meeting. General and administrative costs were unchanged. Research and development expenses increased $800,000. In the first quarter of 2018, our research and development expenses were higher due to higher consulting costs related to the FDA meeting and the submission fees for our MAA application as well as severance expenses. This increase in expenses was offset by lower costs for clinical expense and lower employee related expenses due to a reduction in headcount. The receipt of a tax incentive in Australia offset a portion of the research and development expenses in the first quarter of 2017.

Net loss for the first quarter of 2018 was $4.8 million or $0.32 per share, compared with a net loss of $3.7 million or $0.25 per share in the first quarter of 2017. The increase in net loss resulted primarily from an increase in operating expenses of $800,000 related to the FDA meeting in January and the submission of the MAA to EMA in March for approval of Linhaliq. A decrease in revenue of $200,000 and an increase in interest expense of $100,000 related to the convertible notes was recorded.

Liquidity and Capital Resources and Related Matters

As of March 31, 2018, the Company’s cash and cash equivalents totaled $1.4 million.

In January, Aradigm received a Complete Response Letter (CRL) from the FDA regarding the New Drug Application (NDA) for Linhaliq as a treatment for non-cystic fibrosis bronchiectasis (NCFBE) patients with chronic lung infections with Pseudomonas aeruginosa (P. aeruginosa).

The CRL states that the FDA has determined that it cannot approve the NDA in its present form and provides specific reasons for this action along with recommendations needed for resubmission; the areas of concern include clinical data, human factor validation study and product quality.

The Aradigm Board of Directors approved temporary measures on February 9, 2018 intended to preserve the Company’s cash resources.

In April Aradigm raised $2.0 million through the issuance of bridge notes and obtained commitments for additional monthly funding through September of 2018 totaling $5 million. This $7.0 million along with the cash balance of $1.4 million will be sufficient to fund operations through the third quarter of 2018.

Aradigm is pursuing potential alternatives to resolve our cash position in the short term as well as developing strategic options that would provide for our long term viability. We feel it is very important to bring Linhaliq to commercialization in as many geographies as possible to allow patients suffering from non-cystic fibrosis bronchiectasis (NCFBE) to receive the benefits of Linhaliq. Patients, patient advocacy groups and key opinion leaders have expressed support as we work towards this goal. The MAA was filed in early March and validated for review in late March and that is the first step in achieving regulatory approval in Europe.

About Non-Cystic Fibrosis Bronchiectasis

NCFBE is a severe, chronic and rare disease characterized by abnormal dilatation of the bronchi and bronchioles, frequently associated with chronic lung infections. It is often a consequence of a vicious cycle of inflammation, recurrent lung infections, and bronchial wall damage. NCFBE represents an unmet medical need with high morbidity and mortality that affects more than 150,000 people in the U.S. and over 200,000 people in Europe. There is currently no drug approved for the treatment of this condition.
