V20s up to 37% will be permitted and viewed as a minor deviation, provided that the treating radiation oncologist believes this level of exposure is within patient tolerance. 2.11 Planned radiation cardiac dose V50 >25%.

Has a confirmed histological diagnosis of MPM with histological type epithelioid or biphasic (if biphasic, histology must be predominantly [50%] epithelioid). Histological diagnosis of MPM will be confirmed centrally using specimens or slides from tumor specimens obtained at the time of initial presentation or a subsequent procedure. Central confirmation of diagnosis with immunohistochemistry will be performed, and independent central confirmation will be required for study entry; 4. Measurable disease, per modified Response Evaluation Criteria in Solid Tumors [RECIST] 1.1 (see Section 7) for pleural mesothelioma; 5. Has received a minimum of 1 treatment regimen and a maximum of 2 treatment regimens, which may have been chemotherapeutic and/or immunotherapeutic treatment regimens for MPM which included at least 1 anti-folate and platinum combination regimen;
• Adjuvant or neoadjuvant therapy represent 1 line of therapy each;
• Patients who have undergone primary surgical resection and/or radiation therapy to the pulmonary site are eligible to participate. For clarity, surgical resection and/or radiation therapy to the pulmonary site are not exclusionary and are not considered a line of therapy;
• Treatment that is split between pre-surgical resection and post-surgical resection and is the same regimen will be counted as 1 regimen. Patients meeting this condition should be discussed with the Medical Monitor prior to including the patient in the study; 6. Has a pleural space accessible for IPC or similar device insertion. Patients with a previously inserted IPC or similar device may be enrolled, and the pre-existing IPC or similar device can be used for vector administration as long as it is functional and has no evidence of local infection; 7. Life expectancy 12 weeks in the judgement of the Investigator; 8. Eastern Cooperative Oncology Group (ECOG) status of 1 or 0; 9. Female and male patients:
• Female patients of childbearing potential must have a negative pregnancy test upon entry into this study and agree to use a highly effective method of contraception from Screening until 1 month after the last dose of gemcitabine;
• Highly effective methods of contraception that result in a low failure rate (i.e., <1% per year) when used consistently and correctly include combined (estrogen and progestogen containing) hormonal contraception associated with inhibition of ovulation (oral, intravaginal, or transdermal), progestogen-only hormonal contraception associated with inhibition of ovulation (oral, injectable, or implantable), intrauterine device, intrauterine hormone-releasing system, bilateral tubal occlusion, vasectomized partner, or sexual abstinence;
• True abstinence, when in line with the preferred and usual lifestyle of the patient, is considered a highly effective method only if defined as refraining from heterosexual intercourse during the entire period of study participation and for 1 month after the last dose of gemcitabine. The reliability of sexual abstinence needs to be evaluated in relation to the duration of the clinical study and the preferred and usual lifestyle of the patient. Periodic abstinence (e.g., calendar, ovulation, symptothermal, and post-ovulation method) and withdrawal are not acceptable methods of contraception; and
• Female patients of non-childbearing potential must be either postmenopausal (no menstrual period for a minimum of 12 months) or surgically sterile upon entry into the study;
• Male patients must be either surgically sterile or agree to use a double-barrier contraception method from Screening until 6 months after the last dose of gemcitabine; o Where available and in accordance with local practice, male patients must be advised to seek further advice regarding cryoconservation of sperm prior to gemcitabine treatment due to the possibility of infertility after therapy with gemcitabine; and 10.
