RTOG 0320, "A PHASE III TRIAL COMPARING WHOLE BRAIN RADIATION AND STEREOTACTIC RADIOSURGERY ALONE VERSUS WITH TEMOZOLOMIDE OR ERLOTINIB IN PATIENTS WITH NON-SMALL LUNG CANCER AND 1-3 BRAIN METASTASES"

Study Chair: Paul W. Sperduto, MD, MAPP; 952-442-6000; psperduto@mropa.com



RTOG 0320 chemotherapy options allowed after WBRT have been amended as follows:

Schema: For Arm 2, the text was revised as: "After WBRT, temozolomide may be discontinued at investigator's discretion or continued. If continued, then four weeks after the completion of WBRT, 150mg/m2/day for 5 days/month if prior or concurrent chemotherapy (200mg/m2/day for 5 days/month if no prior chemotherapy) until progression (systemic or CNS) or for a maximum of 6 additional cycles or until the drug is discontinued at the investigator's discretion." For Arm 3, the text was revised as: "After WBRT, the erlotinib may be discontinued at investigator's discretion or continued. If continued, it will continue for a maximum of 6 months after completion of WBRT + SRS."

Section 3.1.4: "Patients who present with synchronous brain metastases at the time of the initial diagnosis of lung cancer are eligible" was added for clarity.

Section 3.1.9: The following text was added to the end of the section for clarity: If the liver function tests, specifically the alkaline phosphatase is elevated above the allowed limit, but this is deemed to be due to bone metastases and not liver metastases, the patient is eligible.

Section 7.1.8.3: A new first sentence was added describing the options after WBRT. A new second paragraph was added for patients who present with synchronous brain metastasis(es) and systemic disease. The end of the fourth sentence was amended as "until progression or for a maximum of 6 additional cycles or until the drug is discontinued at the investigator's discretion."

Section 7.1.8.4: The original section was deleted as this information was incorporated into Section 7.1.8.3. As a result, subsequent Sections 7.1.8.5 and 7.1.8.6 were renumbered as 7.1.8.4 and 7.1.8.5. Cross REFERENCES to these sections within the text were renumbered.

Section 7.1.9: A new first bullet was added. Under the fifth bullet, "After completion of 2 cycles of temozolomide" was deleted for consistency with the other changes to the protocol.

Section 7.2.7.2: The second part of the third sentence was changed to "or erlotinib may be discontinued after the whole brain radiation therapy at the investigator's discretion."

Section 9.3.2: The last sentence of the third paragraph was deleted. A new fourth paragraph was added for patients who present with synchronous brain metastasis(es) and systemic disease.

Section 9.3.3: This section was amended for consistency with the rest of the protocol to indicate that there is an option after WBRT of discontinuing erlotinib at the investigator's discretion.
