The administration of Anamorelin HCl in patients with Non-Small Cell Lung Cancer-Cachexia (NSCLC-C) is expected to increase appetite, lean body mass, weight gain, and muscle strength.

This is a randomized, double-blind, parallel-group, placebo-controlled, extension study to assess the safety and efficacy of Anamorelin HCl in NSCLC-C patients.

Inclusion Criteria:

• Has completed the Day 85 Visit in the original trial (Study HT-ANAM-301 or HT-ANAM-302) and is considered appropriate to continue to receive additional study drug; must start dosing on the extension study within 5 days of completing dosing on the original trial
• ECOG performance status ≤2
• Life expectancy of >4 months at time of screening
• If woman of childbearing potential or a fertile man, he/she must agree to use an effective form of contraception during the study and for 30 days following the last dose of study drug (an effective form of contraception is abstinence, a hormonal contraceptive, or a double-barrier method)
• Must be willing and able to give signed informed consent and, in the opinion of the Investigator, to comply with the protocol tests and procedures

Exclusion Criteria:

• Women who are pregnant or breast-feeding
• Had major surgery (central venous access placement and tumor biopsies are not considered major surgery) within 4 weeks prior to enrollment into the extension study; patients must be well recovered from acute effects of surgery prior to screening; patients should not have plans to undergo major surgical procedures during the treatment period
• Currently taking prescription medications intended to increase appetite or treat weight loss; these include, but are not limited to, testosterone, androgenic compounds, megestrol acetate, methylphenidate, and dronabinol
• Inability to readily swallow oral tablets; patients with severe gastrointestinal disease (including esophagitis, gastritis, malabsorption, or obstructive symptoms) or intractable or frequent vomiting are excluded
• Has an active, uncontrolled infection
• Has known or symptomatic brain metastases
• Receiving strong CYP3A4 inhibitors
• Receiving tube feedings or parenteral nutrition (either total or partial); patients must have discontinued these treatments for at least 6 weeks prior to Day 1, and throughout the study duration
• Other clinical diagnosis, ongoing or intercurrent illness that in the Investigator's opinion would prevent the patient's participation
• Patients actively receiving a concurrent investigational agent, other than Anamorelin HCl
