Neoadjuvant Pembrolizumab in Cutaneous Squamous Cell Carcinoma (DESQUAMATE)

27 lipca 2022 zaktualizowane przez: Dr Rahul Ladwa, Queensland Health

A Phase 2 Study of De-escalation in Resectable, Locally Advanced Cutaneous Squamous Cell Carcinoma With the Use of Neoadjuvant Pembrolizumab - DESQUAMATE

Cutaneous Squamous Cell Carcinoma (cSCC) is typically associated with a high tumour mutation burden, with the majority caused by Ultraviolet (UV) exposure (Pickering et al., 2014).

The use of this trial using neoadjuvant Pembrolizumab in patients with cSCC who will otherwise undergo highly morbid radical surgical resection has multiple potential advantages, including:

  1. Reduction in surgical and radiotherapy morbidity by reducing tumour burden and allowing the appropriate selection of patients to undergo post-operative radiotherapy;
  2. Provision of immediate information about pathological response and
  3. Access to tissue to provide insight into resistance mechanisms and identification of biomarkers of response.

The Investigators hypothesized that the use of neoadjuvant Pembrolizumab could reduce tumour burden allowing appropriate selection of patients undergoing radical surgical resection and adjuvant radiotherapy.

Opis

Inclusion Criteria:

  • Histologically confirmed diagnosis of invasive cSCC that is locally advanced (Stage II-IV on AJCC 8th edition) assessed preoperatively as sufficiently high risk that they will warrant post-operatively RT (as recommended by MDT) who is a candidate for a complete resection.

Note: Participants with tumors arising on cutaneous non-glabrous (hair-bearing) lip with extension onto vermillion (dry red lip) may be eligible after communication and approval from the principal investigator. Participants for whom the primary site is the nose may be eligible after communication and approval from the MDT if the primary site is skin, not nasal mucosa with outward extension to skin. Participants who have squamous cell parotid metastases and have been treated previously for cSCC are permitted. cSCC that has recurred in the same location after 2 or more surgical procedures are not eligible.

  • Participants must have measurable disease based on RECIST 1.1. Lesions situated in a previously irradiated area are considered measurable if progression has been demonstrated in such lesions.
  • Participants must have an Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 1 within 10 days prior to the start of treatment.
  • Participants must have adequate organ function
  • Participants must have a tissue sample adequate for translational research. This tissue sample may be obtained from either a newly obtained core or excisional biopsy.
  • Participants must have a life expectancy of greater than 6 months.
  • Be at least 18 years of age on the day of signing the informed consent. 8. Female participants: Female participants of childbearing potential must have a negative urine or serum pregnancy test within 72 hours prior to receiving the first dose of trial medication. If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required.

Note: In the event that 72 hours have elapsed between the screening pregnancy test and the first dose of study treatment, another pregnancy test (urine or serum) must be performed and must be negative in order for the participant to start receiving study medication.

- A female participant is eligible to participate if she is not pregnant, not breastfeeding, and at least one of the following conditions applies: Not a woman of childbearing potential (WOCBP) as defined in Appendix 1 OR A WOCBP who agrees to use an adequate method of contraception during the treatment period and for at least 120 days after the last dose of study treatment. Note: Abstinence is acceptable if this is the usual lifestyle and preferred contraception for the participant.

- The participant (or legally acceptable representative if applicable) must be willing and able to provide written informed consent for the trial. The participant may also provide consent for Future Biomedical Research. However the participant may participate in the main trial without participating in Future Biomedical Research.

Exclusion Criteria:

  • Participant has metastatic/unresectable cSCC that cannot be potentially cured with surgical resection, radiotherapy, or with a combination of surgery and radiotherapy.
  • Participant has any other histologic type of skin cancer other than invasive squamous cell carcinoma as the primary disease under study, eg, basal cell carcinoma that has not been definitively treated with surgery or radiation, Bowen's disease, merkel cell carcinoma, melanoma.
  • Participants with any prior allogeneic solid organ or hematopoietic stem cell transplantations are excluded.
  • Participant has received prior therapy with an anti-PD-1, anti-PD-L1, or anti-PD-L2 agent or with an agent directed to another stimulatory or co-inhibitory T-cell receptor (eg, CTLA-4, OX-40, CD137).
  • Participant has received prior systemic anti-cancer therapy including investigational agents for cSCC.
  • Participant has received prior radiotherapy to the target lesion.
  • Participant has received a live vaccine within 30 days prior to the first dose of trial drug. 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.
  • Participant is currently participating in or has participated in a trial of an investigational agent or has used an investigational device within 4 weeks prior to the first dose of trial treatment.

Note: Participants who have entered the follow-up phase of an investigational trial may participate as long as it has been 4 weeks after the last dose of the previous investigational agent.

  • Ongoing or recent (within 2 years) evidence of significant autoimmune disease that required treatment with systemic immunosuppressive treatments, which may suggest risk for immune-related adverse events (irAEs) or has a diagnosis of immunodeficiency disorders (such as HIV disease or organ transplantation or hematologic malignancies associated with immune suppression).
  • The following are not exclusionary: vitiligo; asthma; type 1 diabetes; hypothyroidism that required only hormone replacement; or psoriasis that does not require systemic treatment.
  • Participant has a diagnosis of immunodeficiency or is receiving systemic steroid therapy (in dosing exceeding 10 mg daily of prednisone equivalent) or any other form of immunosuppressive therapy within 7 days prior the first dose of trial drug.
  • Participant has a diagnosis and/or has been treated for additional malignancy within the past 3 years prior to allocation.

Note: Participants with cSCC of the skin that have undergone potentially curative therapy are not excluded if not related to current diagnosis.

Note: Participants with basal cell carcinoma of the skin or carcinoma in situ (eg, breast carcinoma, cervical cancer or melanoma in situ) that have undergone potentially curative therapy are not excluded.

Note: Participants with low-risk early-stage prostate cancer, defined as below are not excluded: Stage T1c or T2a with a Gleason score 6 and a prostate-specific antigen (PSA) (10 ng/ml) either treated with definitive intent or untreated in active surveillance that has been stable for the past year prior to trial allocation.

  • Participant has an active autoimmune disease that has required systemic treatment in the past 2 years (eg, with use of disease-modifying agents, anticoagulants, corticosteroids or immunosuppressive drugs). Replacement therapy (eg, thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency) is not considered a form of systemic treatment and is allowed.
  • Participant has a history of (non-infectious) pneumonitis that required steroids or has current pneumonitis.
  • Participant has an active infection requiring systemic therapy.
  • Participant has a known history of Hepatitis B (defined as Hepatitis B surface antigen [HBsAg] reactive) or known active Hepatitis C virus (defined as HCV RNA [qualitative] is detected) infection.

Note: No testing for Hepatitis B or Hepatitis C is required unless mandated by a local health authority.

  • Participant has a history or current evidence of any condition, therapy, or laboratory abnormality that might confound the results of the trial, interfere with the participant's participation for the full duration of the trial, or is not in the best interest of the participant to participate, in the opinion of the treating investigator.
  • Participant has a known psychiatric or substance abuse disorder that would interfere with the participant's ability to cooperate with the requirements of the trial.
  • Participant is pregnant or breastfeeding or expecting to conceive or father children within the projected duration of the trial, starting with the screening visit through 120 days after the last dose of trial treatment.
