About
This research study is studying Lenvatinib in combination with Pembrolizumab in people with human papillomavirus (HPV)-associated recurrent respiratory papillomatosis (RRP).
The names of the study drugs involved in this study are:
- Pembrolizumab
- Lenvatinib
Full description
This is a non-randomized pilot trial in adult male and female subjects diagnosed with recurrent respiratory papillomatosis (RRP) with pulmonary involvement. Twenty subjects who start protocol treatment are planned to be enrolled in this trial to examine the safety and efficacy in this subject population who would be administered the combination of pembrolizumab 200 mg every 3 weeks and lenvatinib 20 mg daily. Subjects will be evaluated each cycle (3 weeks +/- 3 days) in the clinic with a video-recorded flexible laryngoscopy examination to assess clinical response for those with laryngeal involvement. In addition, CT scans of the chest will be obtained every 4 cycles (+/- 7 days) to assess response per RECIST 1.1 criteria. In addition, subjects will complete quality of life questionnaires to assess preference of pembrolizumab and lenvatinib as compared to standard of care treatment for this patient population.

-
A female participant is eligible to participate if she is not pregnant or breastfeeding, and at least one of the following conditions applies:
- Is not a WOCBP as defined below. OR
- Is a WOCBP and must be willing to use 2 methods of birth control, or abstain from heterosexual activity during the intervention period and for at least 120 days after the last dose of pembrolizumab or 30 days post lenvatinib, whichever occurs last.
Women of childbearing potential are those who have not been surgically sterilized or have not been free from menses for greater than 1 year. The methods of surgical sterilization include having had a hysterectomy (removal of the uterus), bilateral oophorectomy (removal of both ovaries), tubal ligation (having your tubes tied), and transvaginal occlusion (blocking the tubes with a coil). The investigator should evaluate the potential for contraceptive method failure (ie, noncompliance, recently initiated) in relationship to the first dose of study intervention

If a urine test cannot be confirmed as negative (eg, an ambiguous result), a serum pregnancy test is required. In such cases, the participant must be excluded from participation if the serum pregnancy result is positive.
-
Men treated or enrolled on this protocol must also agree to use adequate contraception prior to the study, for the duration of study participation, and 4 months after completion of pembrolizumab.
-
Male participants are eligible to participate if they agree to the following during the intervention period and for at least 7 days after the last dose of Lenvatinib:
- Be abstinent from heterosexual intercourse as their preferred and usual lifestyle (abstinent on a long term and persistent basis) and agree to remain abstinent.
OR
• Must agree to use contraception unless confirmed to be azoospermic (vasectomized or secondary to medical cause) as detailed below:
-
Agree to use a male condom plus partner use of an additional contraceptive method when having penile-vaginal intercourse with a WOCBP who is not currently pregnant. Note: Men with a pregnant or breastfeeding partner must agree to remain abstinent from penile-vaginal intercourse or use a male condom during each episode of penile-vaginal penetration.
-
Contraceptive use by men should be consistent with local regulations regarding the methods of contraception for those participating in clinical studies. If the contraception requirements in the local label for any of the study interventions is more stringent than the requirements above, the local label requirements are to be followed
- Ability to complete Patient Medication and Blood Pressure diaries by themselves or with assistance.
- Ability to understand and the willingness to sign a written informed consent document.
Exclusion criteria

Examples of live vaccines include, but are not limited to, the following: measles, mumps, rubella, varicella/zoster (chicken pox), yellow fever, rabies, Bacillus Calmette-Guérin (BCG), and typhoid vaccine. Seasonal influenza vaccines for injection are generally killed virus vaccines and are allowed; however, intranasal influenza vaccines (eg, FluMist®) are live attenuated vaccines and are not allowed.
- Is currently participating in or has participated in a study of an investigational agent within 4 weeks prior to the first dose of study treatment. NOTE: Participants who have entered the follow-up phase of an investigational study may participate as long as it has been 4 weeks after the last dose of the previous investigational agent.
- Has a diagnosis of immunodeficiency or is receiving chronic systemic steroid therapy (in dosing exceeding 10 mg daily of prednisone equivalent) or any other form of immunosuppressive therapy within 7 days prior to the first dose of study drug.
- Has a known additional malignancy that is progressing or has required active treatment within the past 3 years. NOTE: Participants with basal cell carcinoma of the skin, squamous cell carcinoma of the skin, well-differentiated thyroid cancer, follicular lymphoma, carcinoma in situ (e.g. breast carcinoma, cervical cancer in situ) invasive cancer derived from RRP, or other indolent malignancy not requiring active treatment are not excluded.
- History of allergic reactions (greater than or equal to Grade 3) attributed to compounds of similar chemical or biologic composition to pembrolizumab or lenvatinib and/or any of its excipients.
- Has active autoimmune disease that has required systemic treatment in the past 2 years (i.e. with use of disease modifying agents, corticosteroids or immunosuppressive drugs). Replacement therapy (e.g., thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency, etc.) is not considered a form of systemic treatment.
- Has a history of (non-infectious) pneumonitis that required steroids or has current pneumonitis.
- Has an active infection requiring systemic therapy.
- Has a known history of Human Immunodeficiency Virus (HIV) infection. Note: No HIV testing is required unless mandated by local health authority.

- Has urine protein greater than or equal to 1 g/24 hours. Note: Participants with proteinuria > 2+ (greater than or equal to100 mg/dL) on urine dipstick testing (urinalysis) will undergo 24-hour urine collection for quantitative assessment of proteinuria.
Note: Urine dipstick is the preferred method for testing urinary protein, however, urinalysis may be used if the use of urine dipsticks is not feasible.
- Electrolyte abnormalities that have not been corrected.
- Has clinically significant cardiovascular disease within 12 months from first dose of study intervention: history of congestive heart failure greater than New York Heart Association (NYHA) Class II, unstable angina, myocardial infarction or stroke within 6 months of the first dose of study drug, or cardiac arrhythmia associated with hemodynamic instability and requiring medical treatment at screening. Note: Medically controlled arrhythmia would be permitted.

- Prolongation of QTcF interval to >480 msec, as calculated by either the Bazett or Fridericia formula, as per institutional standard.
- Bleeding or thrombotic disorders or subjects at risk for severe hemorrhage. The degree of tumor invasion/infiltration of major blood vessels (e.g. carotid artery) should be considered because of the potential risk of severe hemorrhage associated with tumor shrinkage/necrosis following lenvatinib therapy.
- Has greater than or equal to 1+ proteinuria on urine dipstick testing unless a 24-hour urine collection for quantitative assessment indicates that the urine protein is less than or equal to 1g/24 hours.
- Has clinically significant gastrointestinal malabsorption syndrome or any other condition that might affect the absorption of lenvatinib.
- Has a known history of colitis.

- Participants with history or current evidence of any condition, therapy, or laboratory abnormality that might confound the results of the study, interfere with the subject's participation for the full duration of the study, or is not in the best interest of the subject to participate, in the opinion of the treating investigator.
- Participants with psychiatric illness/social situations that would limit compliance with study requirements.
- Is pregnant or breastfeeding, or expecting to conceive or father children within the projected duration of the study, starting with the screening visit through 120 days after the last dose of trial treatment. Pregnant women are excluded from this study because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with pembrolizumab and/or lenvatinib, and breastfeeding should be discontinued.
