In this study the antibody response after vaccination with the 13-valent pneumococcal conjugated vaccine (PCV13) followed 2 months later by the 23-valent polysaccharide vaccine (PPSV23) in adults with chronic lymphocytic leukemia will be investigated.

Background Patients with chronic lymphocytic leukaemia (CLL) are at increased risk of both invasive pneumococcal disease (IPD) and community acquired pneumonia (CAP) caused by Streptococcus pneumoniae. Therefore, international guidelines recommend pneumococcal vaccination for all CLL patients, preferably before initiation of treatment. The recommended vaccination schedule consists of Prevenar13®, a 13-valent pneumococcal conjugated vaccine (PCV13) followed 2 months later by Pneumovax23, a 23-valent polysaccharide vaccine (PPSV23).

The immunological efficacy of this sequential vaccination schedule in CLL patients is unknown. Previous studies have only investigated responses to either PCV13 or PPSV23 alone. Responses to PPSV23 alone are poor in CLL patients. Responses to the 7-valent pneumococcal conjugated vaccine (PCV7) or PCV13 are higher compared to responses to PPSV23, but lower compared to responses in healthy individuals. More advanced disease stage and lower baseline IgG negatively influence responses to vaccination.

The aim of this observational cohort study is to assess the immunogenicity of the currently recommended vaccination schedule of PCV13 followed by PPSV23 in CLL patients.

2. Methods Study design and population As part of routine care, all adult CLL patients naïve to pneumococcal vaccination and cared for in the Amsterdam UMC-location AMC, Flevoziekenhuis, HagaZiekenhuis, Elisabeth-TweeSteden Hospital, Noordwest Ziekenhuisgroep, Albert Schweitzer Hospital and Ikazia Hospital receive one dose of Prevenar13® followed by one dose of Pneumovax23® 2 months later. According to the current local standard of care for immunosuppressed individuals, the response to vaccination will be assessed by measuring pneumococcal antibody levels before and 4-8 weeks after vaccination.

After obtaining informed consent clinical data will be collected by a trained medical student, nurse or research assistant according to a standardized electronic case report form (Castor EDC). Variables included in the case report form are: age, sex, smoking behaviour, Rai stage (I/II/III), past or ongoing chemotherapy, ongoing steroid treatment, past or ongoing therapy with a monoclonal anti-CD20 antibody (and date of last infusion), baseline total IgG level, baseline lymphocyte count, baseline haemoglobin level, baseline platelet level, baseline pneumococcal IgG levels, post-vaccination pneumococcal IgG levels, date of PCV and PPSV23 vaccine administration, date of antibody measurements, comorbidities (Charlson comorbitiy index).

Laboratory methods and definitions Serotype-specific pneumococcal immunoglobulin G (IgG) concentrations to 5 pneumococcal serotypes shared across both vaccines (6B, 9V, 14, 19F, 23F) and 4 serotypes unique to PPSV23 (8, 15B, 20, 33F) will be determined in the immunology laboratory of the UMC Utrecht. A validated multiplex immunoassay will be used (Luminex® technology). Serologic response will be defined as a ≥4-fold increase in serotype specific anti-pneumococcal IgG for ≥70% of measured. Serologic protection will be defined as an antibody concentration ≥1.3 mcg/ml for ≥70% of all measured serotypes, according to the definition of the American Academy of Allergy, Asthma \& Immunology. In addition, because most previous studies used the WHO cut-off for protection in infants (≥0.35mcg/ml) data will also be analyzed by the infant correlate of protection to be able to compare the results with previous studies.

Patients will continue on a standard dose of lenalidomide as a single agent until progression, or treatment limiting toxicity, following enrollment.

Patients assigned to vaccine therapy will receive injections on day 14 (+/-3 days) of cycles 1, 2, 3 and 6 from enrollment, and then annually thereafter. Prevnar vaccine will be administered with the GM-CSF vaccine administration.

Patients will continue on a standard dose of lenalidomide as a single agent until progression, or treatment limiting toxicity, following enrollment. Patients will also get placebo GM-CSF vaccine and placebo prevnar13. Placebo will be saline.

Patients will continue on a standard dose of lenalidomide as a single agent until progression, or treatment limiting toxicity, following enrollment.

Patients assigned to vaccine therapy will receive injections on day 14 (+/-3 days) of cycles 1, 2, 3 and 6 from enrollment, and then annually thereafter. Patients will also be administered a placebo prevnar13 vaccination. Placebo will be saline.

Each vaccination will consist of three total intra-dermal injections, on day 14 of cycles 1, 2, 3, 6 and annually for a minimum of 36 months in the right and left anterior upper thighs, and one in the non-dominant upper arm (unless contraindicated). In the event that the specified limb is contraindicated, the dominant arm may be used. Vaccine injection sites shall be at least 5 cm at needle entry from the nearest neighbor. The approximate volume of each vaccination injection is approximately 0.7-0.8ml.

GM-CSF vaccine

Patients will be continued on the same dose of lenalidomide as they were prior to being enrolled in the study. Doses of lenalidomide for investigation can vary from 5-25 mg/day, orally on days 1 - 21 followed by 7 days rest (28 day cycle).

Prevnar will be administered at the same time points as the GM-CSF vaccine (day 14 of cycles 1, 2, 3, 6 and annually for a minimum of 36 months), but on the opposite arm from GM-CSF vaccine.

Saline will be used for placebo. Placebo prevnar will be administered at the same time points as the GM-CSF vaccine or Placebo GM-CSF Vaccine (day 14 of cycles 1, 2, 3, 6 and annually for a minimum of 36 months), but on the opposite arm from GM-CSF vaccine or placebo GM-CSF vaccine.

Placebo Prevnar13

Saline will be used for placebo. Each placebo vaccine will consist of three total intra-dermal injections on day 14 of cycles 1, 2, 3, 6 and annually for a minimum of 36 months in the right and left anterior upper thighs, and one in the non-dominant upper arm (unless contraindicated). In the event that the specified limb is contraindicated, the dominant arm may be used. Placebo injection sites shall be at least 5 cm at needle entry from the nearest neighbor. The approximate volume of each injection is approximately 0.7-0.8ml.

This study seeks to determine whether addition of an allogeneic myeloma vaccine can augment clinical responses to lenalidomide in patients with near complete remission (nCR), or complete remission (CR) leading to a significant improvement in progression-free survival.This main objective of this study is to compare the 2-year progression free survival of patients with multiple myeloma in CR or nCR, treated with lenalidomide plus an allogeneic myeloma vaccine in combination with lenalidomide (with or without Prevnar vaccine) or versus placebo in combination with lenalidomide (control arm).

This is a single institution, three- arm, randomized controlled, Phase II study examining the clinical efficacy of an allogeneic GM-CSF secreting myeloma vaccine in combination with lenalidomide (with or without Prevnar) compared to lenalidomide and placebo (control arm).

Patients enrolled in the study must have two disease measurements (including the last one) consistent with a near complete remission (M-spike negative with persistence of immunofixation), or complete remission (M-spike negative, negative immunofixation, and \<5% clonal plasma cells on bone marrow) per criteria for response in a 3 month period. All patients must be minimal residual disease (MRD) positive by NGS sequencing at enrollment.

Prior to enrollment, patients will have been treated with a lenalidomide containing regimen for a minimum of 6 cycles. All patients will continue on a standard dose of lenalidomide as a single agent until progression, or treatment limiting toxicity, following enrollment.

Patients will be randomized to receive either an allogeneic myeloma vaccine and Prevnar vaccine in combination with lenalidomide, or allogeneic myeloma vaccine without Prevnar vaccine in combination with lenalidomide, or lenalidomide in combination with placebo. Patients will receive allogeneic myeloma vaccine or placebo injections on day 14 (+/-3 days) of cycles 1, 2, 3 and 6 from enrollment, and then annually thereafter for up to 3 years. If assigned to allogeneic myeloma vaccine plus Prevnar vaccine arm, Prevnar-13 will be administered with each allogeneic myeloma vaccine. If assigned to either of the two arms that do not include Prevnar, then patients will receive a placebo in lieu of Prevnar on the same schedule. All patients will be followed for a minimum of 3 years.

All patients will continue on a standard dose of lenalidomide. Patients on the myeloma vaccine arm will receive injections in addition to lenalidomide unless otherwise clinically indicated, or until progression. Patients on myeloma plus Prevnar vaccine arm will receive injections of both allogenic myeloma vaccine and Prevnar vaccine in addition to lenalidomide unless otherwise clinically indicated, or until progression. Patients on the myeloma vaccine placebo arm will receive myeloma vaccine placebo on the same schedule as allogeneic myeloma vaccine. If assigned to either of the two arms that do not include Prevnar, then patients will receive placebo in lieu of Prevnar on the same schedule. The placebo will be saline. All patients will be followed for a minimum of 3 years.
