Phase II Randomized Multi-center Trial of Total Neoadjuvant Therapy With and Without CD40 Agonist, APX005M, for Locally Advanced Rectal Adenocarcinoma

2019-10-24 12:49:55 | BioPortfolio


Determine the complete pathologic complete response (pCR) rate in patients with locally advanced rectal adenocarcinoma.


A phase II randomized trial 3:2 with continuous safety assessment for at least 6 patients. Interim analysis after 30 patients for early stopping criteria for futility or efficacy. The null hypothesis is that pCR is 16% and to reject the null hypothesis we aim to show a 48% pCR rate using a 5% one sided type 1 error boundary with 80% power. At interim analysis if the test statistic is less than or equal to 2.488 then the trial will be stopped with rejection of the null hypothesis. If the test statistic is less than or equal to 0.442 then we accept the null hypothesis and stop the trial early.

Medical and Biotech [MESH] Definitions

Preliminary cancer therapy (chemotherapy, radiation therapy, hormone/endocrine therapy, immunotherapy, hyperthermia, etc.) that precedes a necessary second modality of treatment.

Organs which might be damaged during exposure to a toxin or to some form of therapy. It most frequently refers to healthy organs located in the radiation field during radiation therapy.

Drugs used to protect against ionizing radiation. They are usually of interest for use in radiation therapy but have been considered for other, e.g. military, purposes.

A therapeutic approach, involving chemotherapy, radiation therapy, or surgery, after initial regimens have failed to lead to improvement in a patient's condition. Salvage therapy is most often used for neoplastic diseases.

The use of sophisticated methods and equipment to treat cardiopulmonary arrest. Advanced Cardiac Life Support (ACLS) includes the use of specialized equipment to maintain the airway, early defibrillation and pharmacological therapy.
