NCT02454634 : Phase I Trial of IDH1 Peptide Vaccine in IDH1R132H-mutated Grade III-IV Gliomas
PhasePhase 1
AgesMin: 18 Years Max: N/A
Inclusion Criteria:

- Patients present with histologically confirmed diagnosis of an IDH1R132H-mutated
glioma (with or without measurable residual tumor after tumor resection or biopsy)

- Histology may be astrocytoma, oligodendroglioma, or oligoastrocytoma WHO grade III or

- Absence of chromosomal 1p/19q co-deletion in the tumor tissue

- Loss of nuclear ATRX expression in the tumor tissue (partial loss allowed)

- Availability of tumor tissue for molecular screening (FFPE bulk tissue or biopsy)

- Patients have received radiotherapy (54 - 60 Gy) alone, 3 cycles of chemotherapy with
TMZ (150-200 mg/m2, 5/28 days) or standard combined radiochemotherapy with TMZ prior
to enrollment.

- Patients should be immunocompetent (i.e. no concomitant treatment with dexamethasone
(or equivalent), or receive stable/decreasing steroid levels not exceeding 2 mg/day
dexamethasone (or equivalent) during the last 3 days prior to clinical screening; no
severe lymphopenia)

- ?18 years old, smoking or non-smoking, of any ethnic origin and gender

- Karnofsky Performance Status ? 70

- Ability of patient to understand character and individual consequences of the
clinical trial

- Evidence of two informed consent documents personally signed and dated by the patient
(or a witness in case the patient is unable to write) covering the molecular
screening procedure (short IC) and the remaining trial-related procedures (extended
IC) and indicating that the patient has been informed of all pertinent aspects of the
study and that the patient consents to participate in the trial.

- Women of child-bearing potential (WOCBP; i.e., those who have not undergone a
hysterectomy, bilateral salpingectomy and bilateral oophorectomy or who have not been
post-menopausal for at least 24 consecutive months) must have a negative serum
pregnancy test (minimum sensitivity 25 IU/L or equivalent units of HCG) within 72
hours prior to the start of the investigational medicinal product (IMP).

- WOCBP must be using an effective method of birth control to avoid pregnancy
throughout the study and for 24 weeks after the last dose of the IMP. This includes
two different forms of effective contraception (e.g., hormonal contraceptive and
condom, IUD/IUS and condom) or sterilization, resulting in a failure rate less than
1% per year.

- Men must be willing and able to use an effective method of birth control throughout
the study for up to 24 weeks after the last dose of the IMP, if their sexual partners
are WOCBP (acceptable methods see above).

- Patients who are willing and able to comply with scheduled visits, treatment plan,
laboratory tests, and other study procedures

Exclusion Criteria:

- Progressive (incl. pseudoprogression) or recurrent disease after radiation therapy,
chemotherapy or radiochemotherapy based on local MRI assessment

- Previous or concurrent experimental treatment for the tumor. This includes local
therapies such as interstitial radiotherapy or local chemotherapy (i.e. BCNU wafers),
loco-regional hyperthermia, and antiangiogenic therapy (such as bevacizumab)

- Antitumor treatment other than standard radiotherapy and/or standard TMZ
chemotherapy. Daily metronomic TMZ or intensified dosing scheduled as a substitute
for maintenance TMZ cycles are not allowed. (Dose reductions of standard TMZ
chemotherapy are allowed.)

- Abnormal (? Grade 2 CTCAE v4.0) laboratory values for hematology, liver and renal
function (serum creatinine). In detail the following values apply as exclusion

1. Hemoglobin < 10 g/dL (6.2 mmol/L)

2. White blood cell count (WBC) decrease (<3.0 x 109/L) or increase (>10.0 x 109/L)

3. Absolute neutrophil count (ANC) decrease (< 1.5 x 109/L)

4. Platelet count decrease (< 75 x 109/L)

5. Bilirubin > 1.5 x ULN (upper limit of normal according to the performing lab's
reference range)

6. ALT > 3 x ULN

7. AST > 3 x ULN

8. GGT > 2.5 x ULN

9. Serum creatinine increase (> 1.5 x ULN)

- Pregnancy and lactation

- Patients with history or presence of HIV and/or HBV/HCV

- Patients with history or known presence of tuberculosis

- Patients with severe infection(s) or signs/symptoms of infection within 2 weeks prior
to the first administration of the study drug

- Patients who have received a live, attenuated vaccine within 4 weeks prior to the
first administration of the study drug

- Patients with a prior solid organ transplantation or haematopoietic stem cell

- History of hypersensitivity to the IMP or to any drug with similar chemical structure
or to any excipient present in the pharmaceutical form of the IMP

- Participation in other clinical trials or their observation period during the last 30
days before the first administration of the IMP
