3. Have a diagnosis of Hodgkin lymphoma.
4. The patient must meet one of the following criteria:
1. Age =65
2. Considered by the investigator to be ineligible for front-line ABVD combination
chemotherapy due to reasons of medical co-morbidity
5. Have measurable disease based on the Lugano classification
6. Have stage III or IV disease; or disease stage II disease that cannot be irradiated
without unacceptable toxicity in the view of the investigator and patient.
7. Be willing to provide tissue from a "newly-obtained" core or excisional biopsy of a
tumour lesion. Newly-obtained is defined as a specimen obtained up to 8 weeks (56
days) prior to registration. Patients for whom newly-obtained samples cannot be
provided (e.g. inaccessible or patient safety concern) may submit an archived specimen
only upon agreement from the CPI.
8. Have a performance status of 0, 1 or 2 on the ECOG Performance Scale.
9. Demonstrate adequate organ function as defined in Table 2, all screening labs should
be performed within 10 days of registration.
10. Female patient of childbearing potential should have a negative urine or serum
pregnancy within 72 hours prior to registration. If the urine test is positive or
cannot be confirmed as negative, a serum pregnancy test will be required.
11. Female patients of childbearing potential must be willing to use an adequate method of
contraception as outlined in Section 7.14 - Contraception, for the course of the study
through 120 days after the last dose of study medication.
Note: Abstinence is acceptable if this is the usual lifestyle and preferred
contraception for the patient.
12. Male patients of childbearing potential must agree to use an adequate method of
contraception as outlined in Section 7.14 - Contraception, starting with the first
dose of study therapy through 120 days after the last dose of study therapy.
Exclusion Criteria:
1. Is currently participating and receiving study therapy or has participated in a study
of an investigational agent and received study therapy or used an investigational
device within 4 weeks of registration.
2. Is receiving systemic steroid therapy or any other form of immunosuppressive therapy
within 7 days of registration. Is taking chronic systemic steroids (in doses exceeding
10 mg daily of prednisone equivalent) within 7 days prior to registration.
Note: Apart from steroids for palliative purposes specifically for lymphoma-associated
symptoms (prednisolone 50mg or equivalent for up to 10 doses) or patients with asthma
or chronic obstructive pulmonary disease that require intermittent use of
bronchodilators, inhaled steroids, or local steroid injections would not be excluded
from the study.
3. Has a known history of active TB (Bacillus Tuberculosis)
4. Hypersensitivity to pembrolizumab or any of its excipients.
5. Has had a prior anti-cancer monoclonal antibody (MoAb) within 4 weeks prior to
registration or who has not recovered (i.e., = Grade 1 at baseline) from adverse
events due to agents administered more than 4 weeks earlier.
6. Has had prior chemotherapy, targeted small molecule therapy, or radiation therapy
within 2 weeks of registration or who has not recovered (i.e., = Grade 1 or at
baseline) from adverse events due to a previously administered agent.
Note: patients with = Grade 2 neuropathy are an exception to this criterion and may
qualify for the study.
Note: If a patient received major surgery, they must have recovered adequately from
the toxicity and/or complications from the intervention prior to registration.
7. Subject has a history of other active malignancies other than HL within the past 2
years prior to study entry, with the exception of:
- Adequately treated carcinoma in situ of the cervix uteri
- Adequately treated basal cell carcinoma of the skin or localized squamous cell
carcinoma of the skin, previous malignancy confined and surgically resected (or
treated with other modalities) with curative intent and less than 10% risk of
recurrence in next 12 months.
- Untreated monoclonal B lymphocytosis or chronic lymphocytic leukaemia stage 0
with <50% increase in lymphocyte count in preceding 6 months or absolute
lymphocyte count of <10 x10^9/L.
- Myelodysplastic syndrome with no excess of blasts and blood count parameters
meeting inclusion criteria, with no prior disease-modifying therapy.
- Low-risk early stage prostate adenocarcinoma (T1-T2aN0M0 and Gleason score =6 and
PSA =10ng/mL) for which the management plan is active surveillance, or prostate
adenocarcinoma with biochemical-only recurrence with documented PSA doubling time
of > 12 months for which the management plan is active surveillance
8. 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.
9. Has a history of non-infectious pneumonitis that required steroids or has current
pneumonitis.
10. Has an active infection requiring systemic therapy more than oral antibiotics.
11. Has a history or current evidence of any condition, therapy, or laboratory abnormality
that might confound the results of the trial, interfere with the patient's
participation for the full duration of the trial, or is not in the best interest of
the patient to participate, in the opinion of the treating investigator.
12. Has known psychiatric or substance abuse disorders that would interfere with
cooperation with the requirements of the trial.
13. Is pregnant or breastfeeding, or expecting to conceive or father children within the
projected duration of the trial, starting with the pre-screening or screening visit
through 120 days after the last dose of trial treatment.
14. Has received therapy with an anti-PD-1, anti-PD-L1, or anti-PD-L2 agent in the
preceding 12 months.
15. Has a known history of Human Immunodeficiency Virus (HIV) (HIV 1/2 antibodies).
16. Has known active Hepatitis B (e.g., HBsAg reactive) or Hepatitis C (e.g., HCV RNA
[qualitative] is detected).
17. Has received a live vaccine within 30 days of registration. Note: Seasonal influenza
vaccines for injection are generally inactivated flu vaccines and are allowed; however
intranasal influenza vaccines (e.g., Flu-Mist®) are live attenuated vaccines, and are
not allowed.
18. Has known active central nervous system (CNS) metastases and/or carcinomatous
meningitis. Patients with previously treated brain metastases may participate provided
they are stable (without evidence of progression by imaging for at least four weeks
prior to registration and any neurologic symptoms have returned to baseline), have no
evidence of new or enlarging brain metastases, and are not using steroids for at least
7 days prior to registration. This exception does not include carcinomatous meningitis
which is excluded regardless of clinical stability.
