About
This phase I trial tests the safety, side effects, and best dose of MTI-301 in treating patients with solid cancers that have spread from where they first started (primary site) to other places in the body (metastatic) or that cannot be removed by surgery (unresectable) and that have not responded to previous treatment (refractory). MTI-301 is a drug that inhibits an enzyme called SCD1. SCD1 is an enzyme that promotes tumor growth and spread and is upregulated in some cancer types. MTI-301 may disrupt the activity of SCD1, which may lead to reduced tumor growth and/or spread.
Full description
PRIMARY OBJECTIVE:
I. To assess and determine the maximum tolerated dose (MTD) for SCD1 inhibitor MTI-301 (MTI-301).
SECONDARY OBJECTIVES:
I. To determine the toxicity profile with MTI-301. II. To determine objective response rate (ORR), progression free survival (PFS) and duration of response (DOR).
CORRELATIVE RESEARCH:
I. To characterize the pharmacokinetic (PK) profile of MTI-301. II. To assess the levels of SCD1 substrates steric acid, palmitic acid and products oleic acid, palmitoleic acid at baseline, at progression, and at the end of study.
III. To assess immune regulator factors from blood at baseline, at progression, and at the end of study.
OUTLINE: This is a dose-escalation study of MTI-301.
Patients receive MTI-301 orally (PO) once daily (QD) on days 1-28 of each cycle. Cycles repeat every 28 days for up to 6 cycles in the absence of disease progression or unacceptable toxicity. Patients also undergo computed tomography (CT), positron emission tomography (PET)/CT, or magnetic resonance imaging (MRI) and collection of blood samples throughout the study, and undergo tissue sample collection at baseline and at disease progression.
After completion of study treatment, patients are followed up every 3 months for up to 1 year.

- NOTE: If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required.
-
Provide written informed consent.
-
Ability to complete questionnaire(s) by themselves or with assistance.
-
Willingness to provide mandatory blood specimens for correlative research.
-
Willingness to provide mandatory tissue specimens for correlative research.
-
Willing to return to enrolling institution for follow-up (during the Active Monitoring Phase of the study).
Exclusion criteria
-
Any of the following because this study involves an investigational agent whose genotoxic, mutagenic, and teratogenic effects on the developing fetus and newborn are unknown:
-
Pregnant persons
-
Nursing persons
-
Persons who are of childbearing potential who are unwilling to employ adequate contraception.
-
NOTE: For the purpose of this guidance, methods that can achieve a failure rate of less than 1% per year when used consistently and correctly are considered as highly effective birth control methods. Such methods include:
-
Combined (estrogen and progestogen containing) hormonal contraception associated with inhibition of ovulation [Hormonal contraception may be susceptible to interaction with the investigational medicinal product (IMP), which may reduce the efficacy of the contraception method.]:
- Oral
- Intravaginal
- Transdermal
-
Progestogen-only hormonal contraception associated with inhibition of ovulation (Hormonal contraception may be susceptible to interaction with the IMP, which may reduce the efficacy of the contraception method.):
- Oral
- Injectable
- Implantable (Contraception methods that in the context of this guidance are considered to have low user dependency.)
-
Intrauterine device (IUD) (Contraception methods that in the context of this guidance are considered to have low user dependency)
-
Intrauterine hormone-releasing system (IUS) (Contraception methods that in the context of this guidance are considered to have low user dependency.)
-
Bilateral tubal occlusion (Contraception methods that in the context of this guidance are considered to have low user dependency.)
-
Vasectomised partner [Contraception methods that in the context of this guidance are considered to have low user dependency. Vasectomised partner is a highly effective birth control method provided that partner is the sole sexual partner of the women of childbearing potential (WOCBP) trial participant and that the vasectomised partner has received medical assessment of the surgical success.]
-
Sexual abstinence (In the context of this guidance sexual abstinence is considered a highly effective method only if defined as refraining from heterosexual intercourse during the entire period of risk associated with the study treatments. The reliability of sexual abstinence needs to be evaluated in relation to the duration of the clinical trial and the preferred and usual lifestyle of the subject.).
