PTM-101 in Pancreatic Ductal Adenocarcinoma (PDAC)

September 1, 2026 updated by: PanTher Therapeutics

A Phase Ib Dose Escalation/Dose Expansion Study of PTM-101 as an Adjunct to Neoadjuvant Therapy for Treatment Naïve, Borderline Resectable and Locally Advanced Pancreatic Ductal Adenocarcinoma (PDAC)

This is a multi-center, non-randomized, single-arm, open-label, phase Ib, dose escalation/dose expansion study of PTM-101 when combined with neoadjuvant chemotherapy for the treatment of treatment-naïve subjects with borderline resectable and locally advanced pancreatic ductal adenocarcinoma (PDAC).

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available.

Detailed Description

This is a multi-center, non-randomized, single-arm, open-label, phase Ib dose escalation/dose expansion study of PTM-101 in subjects with pancreatic ductal adenocarcinoma (PDAC). Dose escalation will assess the safety of PTM-101 containing escalating doses of paclitaxel to establish the preliminary Recommended Phase II Dose (RP2D) when combined with neoadjuvant chemotherapy for subjects who are treatment-naïve, have borderline resectable or locally advanced PDAC and are eligible for neoadjuvant chemotherapy. Subsequently, the dose expansion portion will expand the number of subjects at the preliminary RP2D to assess the efficacy of PTM-101.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Imaging consistent with primary borderline resectable or locally advanced PDAC. PDAC may be confirmed by histology/cytology either at study-mandated laparoscopy or by prior biopsy/cytology
  • Indicated for laparoscopy
  • No prior therapy of any kind for PDAC
  • Acceptable laboratory values
  • Eastern Cooperative Oncology Group (ECOG) performance status of 0 - 2
  • Ability to provide informed consent
  • No symptomatic pancreatitis
  • No other active medical issues which would confound interpretation of safety monitoring, efficacy results or prevent the subject from study participation
  • Subjects with childbearing potential must agree to use adequate contraception throughout study participation

Exclusion Criteria:

  • Active non-pancreatic cancer that currently requires treatment or is being treated; diagnosis of another malignancy within the past 2 years. This criterion excludes a history of carcinoma in situ of the cervix, superficial non-melanoma skin cancers, or superficial bladder cancer that has been adequately treated, or stage 1 prostate cancer that does not require treatment or requires only treatment with luteinizing hormone-releasing hormone agonists or antagonists if initiated at least 30 days prior to screening). Other potentially indolent cancers may be considered.
  • Contraindications or allergies to paclitaxel, PLGA (poly(lactic-co-glycolic ) acid), or contraindications to implantation of PTM-101 or chemotherapies in protocol (e.g., FOLFIRINOX, gemcitabine, nab-paclitaxel)
  • Known history of human immunodeficiency virus (HIV) or active viral hepatitis
  • Active ongoing infection or autoimmune disease which may preclude laparoscopy, placement of PTM-101, administration of chemotherapy or surgical resection of pancreatic tumor
  • Inability to comply with activities and therapeutic interventions as outlined in the schedule of events
  • Currently enrolled in another investigational drug or device trial
  • Women who are pregnant or breastfeeding or who plan to become pregnant or breastfeed; men who plan to donate sperm or conceive a child
  • Any other medical or surgical conditions, including prior abdominal surgery, that would preclude safe laparoscopy or implantation in the opinion of the investigator

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Dose Escalation
Dose escalation will follow a modified (3+3) design to establish the preliminary RP2D and characterize the safety and pharmacokinetic profile of PTM-101, which will be taken together with all prior clinical data to establish and characterize the preliminary RP2D. A maximum of 12 subjects with treatment-naïve, borderline resectable or locally advanced PDAC will be recruited and receive PTM-101 combined with standard of care neoadjuvant chemotherapy, and be followed for a minimum of 24 months.
Drug: PTM-101
PTM-101, an absorbable drug product containing paclitaxel
Experimental: Dose Expansion
The dose of PTM-101 will be the preliminary RP2D determined from all available clinical data. Up to 20 subjects, inclusive of those already assigned to the preliminary RP2D in the dose escalation part, with treatment-naïve, borderline resectable or locally advanced PDAC will be recruited and receive PTM-101, combined with standard of care neoadjuvant chemotherapy, and be followed for a minimum of 24 months.
Drug: PTM-101
PTM-101, an absorbable drug product containing paclitaxel
