About

The purpose of this research study is to find the dose of the study drug PDR001 that, when given in combination with the drug Panobinostat, results in the best outcomes for metastatic melanoma and non-small cell lung cancer (NSCLC)

Full description

This is an open label, non-randomized Phase Ib study combining PDR001 with HDAC inhibitor Panobinostat in patients with metastatic melanoma and NSCLC who have failed prior Anti PD1 or PD-L1 therapy.

The primary purpose of this study is to find the recommended Phase II dose (RP2D) of Panobinostat in combination with PDR001. Standard 3+3 design will be used for dose escalation or de-escalation. Depending upon tolerability and dosing, the total number of participants may vary from 9-24. Initially patients will start from dose level '0' and there will be 1 dose escalation level '1' and two de-escalation levels ('-1' and '-2'). The maximum number in each dose level will be 6.

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

Inclusion criteria

Patients eligible for inclusion in this study have to meet all of the following criteria:

• Patients must provide written informed consent prior to any screening procedures.
• Age 18 years or older.
• Willing and able to comply with scheduled visits, treatment plan and laboratory tests
• Able to swallow and retain oral medication Panobinostat
• Histologically or cytologically confirmed diagnosis of melanoma or NSCLC
• ECOG performance status of 0-2
• Patients with melanoma and NSCLC must have progressed clinically as determined by the treating physician on a prior line of anti-PD-1/PD-L1 therapy.

Subjects with vitiligo, type I diabetes mellitus, residual hypothyroidism due to autoimmune condition only requiring hormone replacement, psoriasis not requiring systemic treatment, or conditions not expected to recur in the absence of an external trigger are permitted to enroll.
  • History of drug-induced pneumonitis
  • Active infection requiring systemic antibiotic therapy.
  • Known history of Human Immunodeficiency Virus (HIV) infection.
  • Known history of active HBV or HCV infection. Testing for HBV or HCV status is not necessary unless clinically indicated or the patient has a history of HBV or HCV infection.
  • Unresolved diarrhea ≥ CTCAE grade 2 or presence of medical condition associated with chronic diarrhea (such as irritable bowel syndrome, inflammatory bowel disease).
  • Malignant disease, other than that being treated in this study. Exceptions to this exclusion include the following: malignancies that were treated curatively and have not recurred within 2 years prior to study treatment; completely resected basal cell and squamous cell skin cancers; any malignancy considered to be indolent and that has never required systemic chemo or immunotherapy therapy (e.g. ductal carcinoma in situ, some low grade lymphomas, high-grade prostatic intraepithelial neoplasia, monoclonal gammopathy of undetermined significance); and completely resected carcinoma in situ of any type.
  • Any condition that would prevent the patient's participation in the clinical study due to safety concerns, compliance with clinical study procedures or interpretation of study results.
  • Systemic anti-cancer therapy within 2 weeks of the first dose of study treatment. For cytotoxic agents that have major delayed toxicity, e.g. mitomycin C and nitrosoureas, 4 weeks is indicated as washout period. For patients receiving anticancer immunotherapies such as CTLA-4 antagonists, 3 weeks is indicated as the washout period
  • Patients requiring chronic treatment with systemic steroid therapy, other than replacement dose steroids in the setting of adrenal insufficiency. Topical, inhaled, nasal and ophthalmic steroids are allowed.
  • Patients receiving systemic treatment with any immunosuppressive medication (other than steroids as described above). Patients with prior history of allogeneic organ transplant will be excluded.

  • Pregnant or lactating women, where pregnancy is defined as the state of a female after conception and until the termination of gestation, confirmed by a positive hCG laboratory test.

• Women of child-bearing potential, defined as all women physiologically capable of becoming pregnant, unless they are using highly effective methods of contraception during dosing and for 150 days after the last dose of PDR001. Highly effective contraception methods include:

  • Total abstinence (when this is in line with the preferred and usual lifestyle of the patient. Periodic abstinence (e.g., calendar, ovulation, symptothermal, post-ovulation methods) and withdrawal are not acceptable methods of contraception
  • Female sterilization (have had surgical bilateral oophorectomy with or without hysterectomy), total hysterectomy or tubal ligation at least six weeks before taking study treatment. In case of oophorectomy alone, only when the reproductive status of the woman has been confirmed by follow up hormone level assessment
  • Male sterilization (at least 6 months prior to screening). For female patients on the study the vasectomized male partner should be the sole partner for that patient.
  • Use of oral, injected or implanted hormonal methods of contraception or placement of an intrauterine device (IUD) or intrauterine system (IUS), or other forms of hormonal contraception that have comparable efficacy (failure rate <1%), for example hormone vaginal ring or transdermal hormone contraception.
  • In case of use of oral contraception women should have been stable on the same pill for a minimum of 3 months before taking study treatment.
  • Women are considered post-menopausal and not of child bearing potential if they have had over 12 months of natural (spontaneous) amenorrhea with an appropriate clinical profile age appropriate (e.g. generally 40-59 years), history of vasomotor symptoms (e.g. hot flushes) in the absence of other medical justification or have had surgical bilateral oophorectomy (with or without hysterectomy), total hysterectomy or tubal ligation at least six weeks ago. In the case of oophorectomy alone, only when the reproductive status of the woman has been confirmed by follow up hormone level assessment is she considered not of child bearing potential.

• Sexually active males unless they use a condom during intercourse while taking the study treatment and for 150 days after stopping study treatment and should not father a child in this period. A condom is required to be used also by vasectomized men as well as during intercourse with a male partner in order to prevent delivery of the drug via seminal fluid.

• Concomitant use of strong CYP3A4 inducers (Carbamazepine, Modafinil, Rifampin, Rifabutin, Rifapentin, Phenytoin, Phenobarbital and St. John's wort) or strong inhibitors like Cimetidine, Grapefruit juice and Seville oranges as mentioned in appendix E. If patient can come off of these drugs and receive an alternative therapy then they will be eligible as far as time equals 4 half-lives of that medication has elapsed prior to starting protocol therapy.
