A Study of MTL-CEBPA in Combination With a PD-1 Inhibitor in Patients With Advanced Solid Tumours (TIMEPOINT) (TIMEPOINT)
An Open Label Phase 1a/b Study of MTL-CEBPA in Combination With a PD-1 Inhibitor (Pembrolizumab) in Adult Patients With Advanced Solid Tumours
This is an open label Phase 1a/1b study in patients who have advanced solid cancer tumours. Patients will receive MTL-CEBPA (an experimental drug) in combination with pembrolizumab (a drug which has been given approval for use for some tumour types).
The Phase 1a dose escalation part of the study is designed to establish which doses of MTL-CEBPA are safe and well-tolerated when combined with the standard dose of pembrolizumab. Patients recruited to this part of the study will be those whose cancer progressed on standard treatment(s) or for whom no treatments are available.
Phase 1b the dose expansion part of the study will further explore how safe and well-tolerated these two drugs are when combined and will assess if the combination of drugs could potentially reduce the size of tumours. Participants in this part of the study will receive the experimental drug (MTL-CEBPA) at a dose which is considered safe and well-tolerated based on data from the first part of the study (Phase 1a). Participants will remain in the study taking study drugs until either death, or they choose to withdraw from the study.

Detailed Description
Phase 1a comprises three planned dose cohorts (ascending dose, 3+3 design, at the following dose levels: 70 mg/m2 QW, 98 mg/m2 QW, and 130 mg/m2 QW) of MTL-CEBPA combined with standard dose of pembrolizumab (given every 3 weeks). The aim is to assess the safety and tolerability of MTL-CEBPA in combination with pembrolizumab, recruiting patients whose disease progressed on standard of care therapy or for whom no therapy is available.
In the first dose cohort the first participant enrolled will receive MTL-CEBPA treatment at the 70mg/m2 QW dose level. Pembrolizumab (200mg) will be administered on Day 2 of the first cycle and subsequently every 3 weeks whilst participant is on treatment. MTL-CEBPA and pembrolizumab will not be administered on the same day.
Phase 1b of the study will further evaluate safety, tolerability, and assess the clinical activity of MTL-CEBPA and a PD-1 inhibitor (pembrolizumab) in combination.
Participants will receive MTL-CEBPA at a dose considered most appropriate, with regards to safety, tolerability, and efficacy, for further development (based on data from Phase 1a of the study).
Patients with the following (but not limited to) solid tumours will be specifically targeted: breast, lung, ovarian, pancreatic, gall bladder, HCC, neuroendocrine, and cholangiocarcinoma.

Description
Inclusion Criteria:
- Male or female ≥ 18 years
- Histologically or cytologically confirmed diagnosis of any solid tumour
- Participants with advanced solid tumours who have progressed on standard of care therapy or for whom no standard therapy is available
- Participants with advanced pancreatic cancer may also be eligible if they are considered by the treating physician to be unsuitable or have chosen not to take chemotherapy treatment.
- Participants with high grade serous ovarian, fallopian tube and peritoneal ovarian cancer should have been previously treated with a poly adenosine diphosphate ribose polymerase (PARP)inhibitor and should have received no more than 3 prior lines of systemic therapy.
- Participants who are naïve to a prior treatment with an immune checkpoint inhibitor. Participants with lung cancer, renal cancer, mesothelioma or melanoma who have received prior PD-1/PD-L1 or a CTLA4 inhibitor containing treatment will be eligible if they have experienced objective response to this treatment (as defined by Response Evaluation Criteria in Solid Tumours [RECIST] 1.1) as part of their most recent treatment line and have had progressive disease occurring within 6 months of the last dose of their checkpoint inhibitor containing treatment.
- Eastern Cooperative Oncology Group (ECOG)Performance Score0 or 1
- Life expectancy greater than 3 months at the time of recruitment
- Measurable disease as per RECIST 1.1 (Response Assessment in Neuro-Oncology [RANO]for glioblastoma multiforme [GBM]) as assessed by the investigator. Lesions situated in a previously irradiated area are considered measurable if progression hasbeen demonstrated in such lesions.
- In Part 1b of the study, at least one lesion suitable for biopsy (with the exception of brain tumours). If participants have only 1 measurable lesion per RECIST 1.1, the biopsy specimen should be obtained from a non-target lesion.
Haematology and clotting profile at screening with no clinically significant findings:
- Platelet count > 70 x 109/L
Absolute neutrophil count ≥ 1.5 x 109/dl
-≥ 9.0 Serum albumin ≥ 26 g/Lg/dL
- International Normalised Ratio (INR) < 1.5
Adequate renal and hepatic function:
- Serum albumin ≥ 26 g/L
- ALT and AST ≤ 2.5x ULN (≤5 × ULN forparticipants with liver metastases and biliary tract cancer)
- Bilirubin ≤ 1.5 x ULN
- INR≤ 1.5 x ULN
- Serum creatinine ≤ 1.5 x ULN
- Calculated creatinine clearance ≥ 40 mL/min (Cockcroft & Gault). Glomerular filtration rate (GFR) can be used instead of creatinine clearance.
- Negative blood pregnancy test for women of childbearing potential following a menstrual period (within 10 days prior to first drug administration)
For female participants of child-bearing potential, a willingness to use highly effective* contraceptive measures adequate to prevent a new pregnancy for the duration of the study, for at least 6 months after the last dose of MTL-CEBPA or 6 months after the last dose of pembrolizumab, whichever is longer. For women with reproductive potential who use a hormonal method of contraception, concurrent use of a second (barrier) method is recommended.
*Highly effective methods of birth control are defined as those that result in a low failure rate (i.e., less than 1% per year) when used consistently and correctly (e.g., implants, injectables, oral contraceptives, some intrauterine devices, bilateral tubal occlusion, true sexual abstinence in line with the preferred and usual lifestyle of the participant, or vasectomised partner). For EU countries in particular, see additional requirements in: https://www.hma.eu/fileadmin/dateien/Human_Medicines/01-About_HMA/Working_Groups/CTFG/2014_09_HMA_CTFG_Contraception.pdf Male participants with partners of child-bearing potential are required to use barrier contraception plus an additional contraceptive method that together result in a failure rate of <1% per year during the treatment period and for at least 3 months after the last dose of MTL-CEBPA or 4 months after the last dose of pembrolizumab, whichever is longer. Male participants will also be advised to abstain from sexual intercourse with pregnant or lactating women, or to use condoms. Abstinence is only acceptable if it is in line with the preferred and usual lifestyle of the participant. Periodic abstinence (e.g., calendar, ovulation, symptothermal, post-ovulation methods), declaration of abstinence for the duration of exposure to investigational medicinal product (IMP), and withdrawal are not acceptable methods of contraception.
•Note: a woman is considered of child-bearing potential following menarche and until becoming post-menopausal unless permanently sterile. Permanent methods of sterilisation include hysterectomy, bilateral salpingectomy and bilateral oophorectomy. A post-menopausal state is defined as no menses for 12 months without an alternative medical cause(For EU countries in particular please refer to: www.hma.eu/fileadmin/dateien/Human_Medicines/01-About_HMA/Working_Groups/CTFG/2014_09_HMA_CTFG_Contraception.pdf)
