Evaluating MPD-1 for advanced solid tumors

A Phase I, Open-label, Single-center, Dose-escalation and Dose-finding Clinical Trial to Evaluate the Safety, Tolerability and Pharmacokinetics of MPD-1 in Patients With Advanced Solid Tumor

What this trial studies

This Phase I clinical trial is designed to assess the safety, tolerability, and pharmacokinetics of MPD-1 in patients with advanced solid tumors. It is an open-label, single-center study that employs a dose-escalation and dose-finding approach. Participants must have confirmed metastatic or unresectable tumors that have progressed despite standard therapies, with specific genetic markers such as KRAS mutations or PTEN loss. The trial aims to gather critical data on how the drug is processed in the body and its potential effectiveness in this patient population.

Who should consider this trial

Good fit: Ideal candidates are adults aged 19 to 75 with confirmed advanced solid tumors and specific genetic markers indicating resistance to standard treatments.

Not a fit: Patients who have not experienced progression on standard therapies or those without the required genetic markers may not benefit from this study.

Why it matters

Potential benefit: If successful, this trial could provide a new treatment option for patients with advanced solid tumors who have exhausted existing therapies.

How similar studies have performed: While this approach is novel in its specific application, similar studies targeting advanced solid tumors with specific genetic markers have shown promise in the past.

7. albumin ≥ 2.5 g/dL
8. serum creatinine ≤ 1.5 times the normal upper limit
9. INR ≤ 1.5 times the normal upper limit 7) Patients with Eastern Cooperative Oncology Group (ECOG) performance status ≤ 1 8) Patients with an expected survival period of more than 12 weeks 9) Patients who have recovered from previous therapy-related adverse event to Common Terminology Criterion for Adverse Events (CTCAE) version 5.0 grade 1 or below or to C1D1 levels (However, sHair loss (regardless of grade), subjects can be enrolled if they have with hair loss (regardless of grade) or peripheral neuropathy below grade 2 or laboratory test results show that they do not meet the exclusion criteria) can be enrolled.) 10) Patients, who after understanding all the relevant information of this clinical trial, decides to participate, and voluntarily signed a written agreement.

Exclusion Criteria:

1. Within 4 weeks prior to the C1D1, subjects who underwent surgery, chemotherapy (cytotoxic, targeted antitumor drugs), immunotherapy, biological or hormonal therapy, or radiation therapy at areas exceeding 30% of bone marrow for the treatment of this clinical trial's target disease
2. Participation in other interventional clinical trials (administration of investigational new drugs or use of investigational medical devices) within 4 weeks prior to C1D1
3. Subjects who are identified with the following comorbidities during screening

   \- Clinically significant symptomatic or uncontrolled central nervous system metastasis (but can participate in this clinical trial if systemic corticosteroids have not been administered for more than 2 weeks prior to C1D1 and the condition is stable)
   * Heart disease that could affect this clinical trial (left ventricular ejection fraction (LVEF) \<50%, congestive heart failure with New York Heart Association (NYHA) class II or higher, history of myocarditis, myocardial infarction or unstable angina within 24 weeks before C1D1, uncontrolled cardiac dysrhythmia by appropriate medication, coronary artery disease, etc.)
   * History of thrombosis (e.g., thrombophlebitis, etc.)
   * Uncontrolled hypertension (systolic blood pressure \> 160 mmHg or diastolic blood pressure \> 100 mmHg)
   * Clinically significant ascites
   * Subjects who are infected with or carrying hepatitis B virus (HBV) or hepatitis C virus (HCV)\* \* When screening, serology tests show that any one of the following is positive: hepatitis B surface antigen (HBsAg), hepatitis B core antibody-immunoglobulin M (HBcAb-IgM), and hepatitis C virus antibody (HCV Ab) (However, if the HCV Ab test result is suspected to be false positive or positive due to past infection, HCV RNA test may be performed at each institution under the judgement of investigator and the HCV Ab and RNA test results are integrated to decide whether HCV is infected.)
4. The following medical history is identified during screening

   * Chickenpox or varicella zoster infection within 12 weeks prior to C1D1
   * Uncontrolled active infectious diseases including known human immunodeficiency virus (HIV) positives

   * Vaccination against yellow fever within 4 weeks prior to C1D1
   * Penitoin within 1 week prior to C1D1
   * G-CSF administration to correct absolute neutrophil count (ANC) levels within 2 weeks prior to C1D1

     \-- Transfusion of packed red cells or platelets to correct platelets or hemoglobin levels within 2 weeks prior to C1D1

However, periodic abstinence (menstrual cycle, mucus method, symptomatic body temperature method, etc.), resection, and withdrawal method (coitus interruptus) are not recognized as appropriate contraception methods.
8. Subjects who have a history of allergies to doxorubicin or the excipient of MPD-1 or is suspicious of allergy
