Who cannot join

  • Patients should not have had prior systemic therapy alone administered in the recurrent/ or metastatic setting. If a patient received platinum based systemic therapy which was completed more than 6 months prior to signing consent given as part of multimodal curative intent treatment for locally advanced HNSCC (This includes both definitive concurrent chemoradiation and adjuvant chemoradiation) the patient is still eligible,

Subjects with vitiligo, Grave's disease, or psoriasis not requiring systemic therapy or resolved childhood asthma/atopy would be an exception to this rule. Subjects that require intermittent use of bronchodilators or local steroid injections would not be excluded from the study. Subjects with hypothyroidism or Sjogren's syndrome will not be excluded from the study.
  • Has a history of non-infectious pneumonitis that required steroids, evidence of interstitial lung disease, or currently active non-infectious pneumonitis.

  • Peripheral sensory neuropathy > grade 2 by CTCAE v5.0
  • Has a history or current evidence of any condition, therapy, or laboratory abnormality that might confound the results of the trial, interfere with the subject's participation for the full duration of the trial, or is not in the best interest of the subject to participate, in the opinion of the treating investigator.

About this study

Official title: Phase II Trial of Pulsed Dose Chemotherapy Plus Pembrolizumab in the First Line Treatment of Recurrent/Metastatic HNSCC

The rationale for the new sequence of pulsed dose chemotherapy proposed in this trial is based on the hypotheses that current standard dosing of chemotherapy plus pembrolizumab ultimately suppresses the immune system and has a negative effect on the efficacy of the anti-PD-1 monoclonal antibody (mAb) therapy and that chemotherapy given after anti-PD-1 mAb therapy is associated with higher efficacy.

Read the detailed description

Chemotherapy plus pembrolizumab plays a significant role in standard of care frontline treatment in R/M HNSCC and there is a need for improvement in outcomes with this combination therapy. This trial importantly will test a new dosing and sequence of pembrolizumab and chemotherapy, with the primary goal of improving efficacy but secondarily also has the potential to be better tolerated than standard dosing. Additionally, this trial may have applicability to other solid tumor types where chemotherapy and anti-PD-1 mAb are currently combined. Based on current data showing that current repetitive frequent dosing of chemotherapy may lead to immunosuppression and a detrimental effect on the prolonged duration of response expected from pembrolizumab, and that chemotherapy efficacy may be higher after anti-PD-1 mAb therapy, this trial will test a new sequence starting with pembrolizumab with less frequent dosing of chemotherapy (pulsed dose) to maximize synergy and improve efficacy. Specifically, patients will be treated with pembrolizumab 200 mg IV q3w with carboplatin/paclitaxel given starting with cycle 2 of pembrolizumab and continued thereafter every 3rd cycle of pembrolizumab (q9w) for a total of 4 cycles of carboplatin/paclitaxel. After completion of the 4th cycle of carboplatin/paclitaxel, pembrolizumab maintenance will be continued at 400 mg IV q6w for 12 cycles for a total of 2 years of therapy. Carboplatin/paclitaxel is being used as the chemotherapy doublet in this trial because there is more data for immunogenicity and higher efficacy post anti-PD-1 with taxanes, the potential to be better tolerated than infusional 5-fluorouracil (5FU), and physician preference for this chemotherapy backbone including in our Hillman network. Importantly, prior to the immunotherapy era, a phase III trial compared platinum/taxane to platinum/5FU in R/M HNSCC and found no difference in efficacy between these regimens, and outcomes in combination with pembrolizumab are comparable.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • PembrolizumabDrug

    Also called Keytruda®

    Immunotherapy that works by helping the immune system to kill cancer cells by targeting and blocking a protein called PD-1 on the surface of certain immune cells called T-cells. Blocking PD-1 triggers the T-cells to find and kill cancer cells.

  • CarboplatinDrug

    A chemotherapy drug that contains the metal platinum. It stops or slows the growth of cancer cells and other rapidly growing cells by damaging their DNA.

  • PaclitaxelDrug

    Also called Taxol

    A chemotherapeutic agent used as a treatment for various cancers; paclitaxel is a mitotic inhibitor.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. 6-month Progression-free Survival (PFS)

    Proportion of patients alive and without disease progression at 6 months after starting treatment, per RECIST v1.1. Progressive Disease (PD): At least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study (this includes the baseline sum if that is the smallest on study). In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm. (Note: the appearance of one or more new lesions is also considered progression).

    Measured: At 6 months

Secondary outcomes (4)

  1. Adverse Events (AE) and Serious Adverse Events (SAE) Related to Treatment

    Proportion of patients that experience Adverse Events or Serious Adverse Events related to treatment, per CTCAE v5.0. The maximum grade for each toxicity type will be recorded for each patient.

    Measured: Up to 2 years

  2. Overall Response Rate (ORR)

    Proportion of patients with Complete Response (CR) or Partial Response (PR) per RECIST v1.1. Complete Response (CR): Disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to <10 mm. Partial Response (PR): At least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters.

    Measured: Up to 2 years

  3. Duration of Response (DOR)

    Time from start of treatment to disease progression or death in patients who achieve Complete Response (CR) or Partial Response (PR) per RECIST v1.1. Complete Response (CR): Disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to <10 mm. Partial Response (PR): At least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters.

    Measured: Up to 4 years

  4. Overall Survival (OS)

    Median number of months from start of treatment that patients remain alive.

    Measured: Up to 4 years
