HPV Vaccine PRGN-2009 Alone or in Combination With Anti-PDL1/TGF-Beta Trap (M7824) in Subjects With HPV Associated Cancers

Running, not enrolling · Phase 1/Phase 2

Conditions studied: HPV Positive Cancer, Vulvar, Vaginal, Penile, Rectal Cancer, Anal Cancer, Oropharyngeal Cancer, Cervical Cancer

In brief

Background: For some cancers associated with human papillomavirus (HPV), standard treatments are not helpful. Researchers want to see if a vaccine for HPV combined with a drug called M7824 (MSB0011359C) has a better effect on these cancers than when they work alone. Objective: To find a safe dose of HPV vaccine alone or combined with M7824. Also, to test if either HPV vaccine alone or combined with M7824 causes a better immune response. Eligibility: People ages 18 and older with locally advanced or metastatic HPV associated cancer (Phase I) or stage II or III p16-positive oropharyngeal cancer (Phase II) Design: Participants will be screened with: Medical history Physical exam Blood, urine, and heart tests Possible photos of skin lesions Computed tomography (CT), magnetic resonance imaging (MRI), or nuclear bone scan: Participants will lie in a machine that takes pictures of the body. For the CT scan, they may have a contrast agent injected into a vein. Participants may have up to 2 tumor biopsies. For participants in Phase II, this may be performed with a thin tube placed through the nose into the airway. Participants will receive the HPV vaccine alone or with M7824. For participants on the Phase II, they will receive two doses of HPV vaccine under the skin either alone or with M7824 as an infusion spaced two weeks apart. This will be done prior to their planned chemoradiation or surgery. For participants on the Phase I, they will get the HPV vaccine injected under the skin 2 to 3 times in the first month. Then they will have a booster every 4 weeks. They will receive M7824 as an infusion into a vein every 2 weeks. Treatment will last up to 1 year. After they stop treatment, participants will have a visit within 4 weeks. They will then be contacted for long-term follow-up every year, for the rest of their lives. ...

You may not qualify if…

• Participants with prior investigational drug, live vaccine, chemotherapy, immunotherapy or any prior radiotherapy (except for palliative bone directed therapy) within the past 28 days prior to the first drug administration except if the investigator has assessed that all residual treatment-related toxicities have resolved or are minimal and feel the participant is otherwise suitable for enrollment. Participants may continue adjuvant hormonal therapy in the setting of a definitively treated cancer (e.g., breast).
• Major surgery within 28 days prior to the first drug administration (minimally invasive procedures such as diagnostic biopsies are permitted).
• Known active brain or central nervous system metastasis (less than a month out from definitive radiotherapy or surgery), seizures requiring anticonvulsant treatment (<3 months) or clinically significant cerebrovascular accident (<3 months). In order to be eligible participants must have repeated central nervous system (CNS) imaging at least a month after definitive treatment showing stable CNS disease. Participants with evidence of intra-tumoral or peritumoral hemorrhage on baseline imaging are also excluded unless the hemorrhage is grade =< 1 and has been shown to be stable on two consecutive imaging scans.
• Pregnant women are excluded from this study because M7824 and PRGN-2009 vaccine have not been tested in pregnant women and there is potential for teratogenic or abortifacient effects. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with these immunotherapies, breastfeeding should be discontinued if the mother is treated on this protocol.
• Only for Phase I, Arm 1B: Active autoimmune disease that might deteriorate when receiving an immunostimulatory agent with exception of:
• Diabetes type I, eczema, vitiligo, alopecia, psoriasis, hypo- or hyperthyroid disease or other mild autoimmune disorders not requiring immunosuppressive treatment;
• Administration of steroids for other conditions through a route known to result in a minimal systemic exposure (topical, intranasal, intro-ocular, or inhalation) is acceptable;
• Subjects on systemic intravenous or oral corticosteroid therapy with the exception of
• physiologic doses of corticosteroids (=< the equivalent of prednisone 10 mg/day) or other immunosuppressors such as azathioprine or cyclosporin A are excluded on the basis of potential immune suppression. For these subjects these excluded treatments must be discontinued at least 1 weeks prior to enrollment for recent short course use (=< 14 days) or discontinued at least 4 weeks prior to enrollment for long term use (> 14 days). In addition, the use of corticosteroids as premedication for contrast-enhanced studies is allowed prior to enrollment and on study.
• Only for Phase I: Subjects with a history of serious intercurrent chronic or acute illness, such as cardiac or pulmonary disease, hepatic disease, bleeding diathesis or recent (within 3 months) clinically significant bleeding events, known left ventricular ejection fraction <50% (confirmation of ejection fraction (EF) > 50% is not required for eligibility), history of myocarditis, or recent myocardial infarction (within 6 months), or other illness considered by the Investigator as high risk for M7824 drug treatment.
• Only for Phase I: Subjects refusing to accept blood products as medically indicated.
• History of second malignancy within 3 years of enrollment except for the following: adequately treated localized skin cancer, cervical carcinoma in situ, superficial bladder cancer, other localized malignancy which has been adequately treated or malignancy which does not require active systemic treatment (e.g., low risk chronic lymphocytic leukemia (CLL)). For participants enrolled on the phase I portion of the protocol a second HPV driven malignancy is allowed.
• Only for Phase I, Arm 1B: Subjects with a known severe hypersensitivity reaction to monoclonal antibodies or its excipients (grade >/= 3 National Cancer Institute (NCI)-Common Terminology Criteria for Adverse Events (CTCAE) v5) will be evaluated by the allergy/immunology team prior to enrollment.
• Prior allogenic tissue/solid organ transplant.
• For participants who may receive M7824: previous life-threatening side effects resulting from prior checkpoint inhibitor therapy.
• Participants with pulse oximetry < 92% on room air at screening.
• Participants unable to provide informed consent.
• Participants whose inclusion in the trial would in the judgement of the principal investigator (PI) lead to time from diagnosis to initiation of curative treatment of>70 days (Arm 2A only).
