Brief summary: Advanced cancer patients often require palliative (pain relieving) radiotherapy to treat cancer-related symptoms. The delivery of radiation requires patients to lie still on a hard flat surface, which can result in significant acute (intense) pain and/or breakthrough cancer pain (sudden sharp or stabbing pain), especially when painful bone metastases are present. The current care for most cancer patients receiving radiation is to take an oral (by mouth) opioid medication before the radiation treatment. The pain relieving effects of these medications can take about one hour and can last for 3 to 6 hours, which does not follow the time course of when breakthrough cancer pain occurs.

Lazanda is a pain medication delivered via an intranasal route and is already approved by the U.S. Food and Drug Administration (FDA) for the management of breakthrough cancer pain for patients who are already receiving opioids and who can tolerate opioids for the treatment of cancer pain. Lazanda is fast-acting and convenient for patients to take. The purpose of this study is to assess the change in pain intensity during palliative radiotherapy following study treatment with Lazanda. This study will also explore the impact of the study treatment on the efficiency in delivering the radiation therapy

Detailed description: This is a Phase II, single-center, single-arm, Open-Label Study to Evaluate Lazanda in Cancer Patients Receiving Palliative Radiation.

The primary objective of this study is to assess the change in patient reported positional pain intensity (PI) as measured by an 11-point numerical rating scale (NRS-11) in cancer patients with bone metastases assessed at a simulation visit and each subsequent daily palliative radiation fraction. The primary objective will be measured using the pain intensity difference (PID) of the NRS-11 from the time of laying down on the hard surface (0 minutes/ PI0) to the 15 minutes after laying down on the hard surface timepoint at baseline (the simulation visit) and at each subsequent study visit (PID15= PI0- PI15).

Study participants will be recruited across all oncology disease teams. Potential participants will be identified in weekly palliative care or disease team patient triage meetings. In order to meet eligibility for participation, a patient must be greater than or equal to 18 years old, have histologically-confirmed cancer with symptomatic bone metastases, an Eastern Cooperative Oncology Group (ECOG) performance status less than or equal to 3, and are planned to receive hypofractionated palliative radiation less than or equal to 10 fractions. Qualifying subjects must be opioid-tolerant, defined as greater than or equal to 60mg morphine or equivalent, and be on a stable dose of oral opioids for greater than or equal to 1 week. Stable baseline opioid dosage is defined as a dosage that does not fluctuate by more than 50% from the average dosage over one week prior to screening. Patients must also be on a stable dose of adjuvant pain therapies for one week prior to screening. Patients will be excluded if they are receiving or have received another investigational agent within 30 days or monoamine oxidase inhibitor within 14 days prior to Lazanda administration, have known hypersensitivity to fentanyl or opioids, have known, planned interventional procedures such as surgery that may affect study outcomes, are pregnant or nursing, have a disorder or current medication use likely to adversely affect normal functioning of the nasal mucosa, have uncontrolled or rapidly escalating background pain, or are medically unstable, require immobilization with a thermoplastic mask for radiation treatment.

Upon confirmation of all eligibility criteria, the subject will be enrolled. Each enrolled subject will undergo a baseline evaluation on a mock hard surface within 1 week prior to the time of CT simulation, to establish baseline NRS pain scores.

Subject will receive Lazanda at their mock hard surface visit , radiation simulation visit and again as pre-medication prior to each radiation treatment (fraction), for an estimated treatment period of 10 days based on the patient's radiation treatment plan. Lazanda will be self-administered intranasally by subjects participating in this study.

NRS pain scores will be collected at three time points at baseline : 15 minutes prior to laying on the hard surface (T-15), at the time of laying on the hard surface (T0), and at 15 minutes after laying on the hard surface(T+15). Exact time of each pain score rating will also be collected.

After the mock visit subject will then undergo radiation therapy simulation procedures (within approximately 2 weeks of radiation therapy) followed by hypofractionated radiation therapy, according to University of California, San Diego (UCSD) Radiation Oncology standard procedure and treatment plan determined by the subject's radiation oncologist. During radiation simulation and daily during each visit to the radiation center for hypofractionation delivery, subjects will have vital signs and weight collected. An ECOG performance status will also be assessed daily during radiation therapy. At the time of radiation simulation and daily during radiation therapy, subjects will complete the BPI-sf , Medication Use Diary, Laxation Diary, and Nausea/Vomiting Diary. As with the mock hard surface evaluation, NRS pain scores will also be collected at three time points during each visit to the radiation center.

Subjects will receive study drug, Lazanda at 100mcg dose, 15 minutes prior to simulation (T-15) at the radiation therapy simulation visit. Lazanda dose titration will follow the guidelines as indicated in the product package insert from the radiation simulation visit through the end of radiation therapy.

Subjects will undergo a post treatment follow-up period after completion of their radiation therapy. During this follow-up period, subjects will complete the BPI-sf, Medication Use Diary, Laxation Diary , and Nausea/Vomiting Diary daily for 2 days.
