We are maintaining our Neutral stance on MannKind Corporation (MNKD) with a target price of $4.00.

Valencia, California-based MannKind is a biopharmaceutical company focused on the discovery, development and commercialization of therapeutic products for diabetes, cancer and inflammatory and autoimmune diseases. The company’s lead pipeline candidate Afrezza (formerly known as Afresa) is an inhaled insulin for the treatment of type I or type II diabetes.

In January 2011, MannKind received a setback when the US Food and Drug Administration (FDA) issued a second complete response letter (CRL) for Afrezza. While issuing the CRL, the US regulatory authority asked for additional information besides asking MannKind to conduct more trials. The requirement of additional trials will push up MannKind’s research and development expenses.

Management believes that the current cash balance will last till the end of 2011. Consequently it will have to tap the capital market to raise additional resources. Inability to raise sufficient funds could jeopardize Afrezza’s future development path.

MannKind intends to meet the FDA officials regarding the issue. Following the receipt of the second CRL, MannKind trimmed its work force by approximately 41% and cancelled its insulin supply deal with Merck’s (MRK) subsidiary, Organon. The headcount reduction coupled with the termination of the deal is expected to bring down operating costs at MannKind.

The magnitude of the setback is significant as all other candidates at MannKind are in early stages of development. These concerns have caused us to increase our 2011 loss estimate.

The setback causes us to believe that there is limited scope for upside from current levels at MannKind. We prefer to remain on the sidelines until we have more visibility on the approval process for Afrezza and retain our ‘Neutral’ stance on the stock.
