Cerulean Reports Fourth Quarter 2014 Corporate Highlights and Financial Results
Phase 1b/2 trial of CRLX101 in renal cell carcinoma achieves primary endpoint
Closed debt facility for up to
"Today, Cerulean made the important announcement that the Phase 1b/2
trial of CRLX101 in combination with Avastin® in relapsed
renal cell carcinoma, or RCC, that completed enrollment in the fourth
quarter met its primary endpoint," said
Friedman continued, "In addition to completing enrollment of the Phase 1b/2 RCC trial in the fourth quarter, Cerulean achieved another significant clinical milestone: our second platform-generated candidate, CRLX301, moved into clinical development when the first patient was treated in a Phase 1/2a trial in solid tumor malignancies in December 2014."
Fourth Quarter 2014 Corporate Highlights
-
Completed enrollment in a Phase 1b/2 trial of CRLX101 plus Avastin in
relapsed RCC, leading to the following positive top-line data reported
today:

Executed a clinical research agreement with
GOG Foundation, Inc. , to study CRLX101 in combination with weekly paclitaxel in relapsed ovarian cancer patients -
Announced top-line data (highlighted earlier in this release) from a
Phase 1b/2 investigator-sponsored trial (IST) of CRLX101 plus Avastin
in patients with relapsed RCC:
-
In an ongoing trial that completed enrollment in
December 2014 , the trial met its primary endpoint of at least 50% of patients achieving four months PFS -
As of the date of the abstract submission to the
American Society of Clinical Oncology (ASCO) Annual Meeting, the mPFS was 9.9 months - The ORR at the time of the ASCO submission was 23%
- Seven patients were still being treated at the time of the ASCO submission
-
The Principal Investigator,
Stephen Keefe , M.D., has submitted to present updated data at the 2015 ASCO Annual Meeting - Final data will be submitted for publication in a peer-reviewed journal later this year
-
In an ongoing trial that completed enrollment in
-
Announced interim clinical data from two ongoing ISTs:
-
In an ongoing Phase 2 trial of CRLX101 plus Avastin in patients
with relapsed ovarian cancer:
- One of the first nine patients enrolled in the trial achieved a partial response according to RECIST criteria
- An additional one of nine patients achieved tumor reduction in excess of 20%
- Nine of nine patients achieved stable disease or better
- Four of nine patients are still on treatment
- There have been no serious adverse events to date using Avastin at its standard dosing and CRLX101 at its MTD
- Patients continue to enroll on this trial
-
In an ongoing Phase 1b/2 trial of CRLX101 plus chemoradiotherapy
(CRT) in patients with non-metastatic rectal cancer:
- Two of the first eight patients enrolled in the trial achieved a pathologic complete response (pCR)
- Seven of eight patients achieved an AJCC/UICC tumor regression score of 0 or 1 on a scale of 0 to 3, with 0 being the best (a pCR) and 3 being the worst (poor treatment response)
- Two other patients have been treated but have not yet had surgeries to determine their outcomes
- There were no dose limiting toxicities in the nine patients enrolled in the Phase 1b stage of the trial, leading to establishment of the MTD and RP2D as 15 mg/m2
- Patients continue to enroll on this trial, and the trial has advanced to the Phase 2 stage
-
In an ongoing Phase 2 trial of CRLX101 plus Avastin in patients
with relapsed ovarian cancer:
Anticipated Upcoming Milestones
During the remainder of 2015, Cerulean expects:
-
The presentation of updated data for the Phase 1b/2 IST of CRLX101
plus Avastin in relapsed RCC by
Dr. Keefe at the 2015 ASCO Annual Meeting - The announcement of updated clinical results from the ongoing Phase 2 IST of CRLX101 plus Avastin in relapsed ovarian cancer
- The announcement of updated clinical results from the ongoing Phase 1b/2 IST of CRLX101 plus CRT in non-metastatic rectal cancer
- The announcement of clinical results from the ongoing Phase 1 trial of CRLX301
In 2016, Cerulean expects:
-
The announcement of clinical results from the planned Phase 1b trial
with
GOG Foundation of CRLX101 plus weekly paclitaxel in relapsed ovarian cancer - The announcement of the PFS endpoint and ORR data from the Phase 2 randomized RCC trial
Brief Financial Summary
As of
Cerulean estimates that its current cash and cash equivalents will fund operations into the third quarter of 2016 and allow it to fund:
- the ongoing randomized Phase 2 clinical trial of CRLX101 plus Avastin in RCC

- the Phase 1b/2 IST of CRLX101 plus CRT in non-metastatic rectal cancer
- the Phase 1 clinical trial of CRLX301 in solid tumors
-
the planned Phase 1b clinical trial in collaboration with

About CRLX101
CRLX101 is a dynamically tumor-targeted nanoparticle-drug conjugate (NDC) designed to concentrate in tumors and slowly release its anti-cancer payload, camptothecin, inside tumor cells. CRLX101 inhibits topoisomerase 1 (topo 1), which is involved in cellular replication, and hypoxia-inducible factor-1α (HIF-1α), which research suggests is a master regulator of cancer cell survival mechanisms thought to promote drug and radiation resistance. CRLX101 has shown activity in four different tumor types, both as monotherapy and in combination with other cancer treatments. CRLX101 is currently in Phase 2 clinical development and has been dosed in more than 250 patients.
About CRLX301
CRLX301 is a dynamically tumor-targeted NDC designed to concentrate in tumors and slowly release its anti-cancer payload, docetaxel, inside tumor cells. In preclinical studies, CRLX301 delivers up to 10 times more docetaxel into tumors, compared to an equivalent milligram dose of commercially available docetaxel and was superior to docetaxel in seven of seven animal models, with a statistically significant survival benefit seen in five of those seven models. In addition, preclinical data show that CRLX301 had lower toxicity than has been reported with docetaxel in similar preclinical studies. CRLX301 is currently in Phase 1 clinical development.
About
The Cerulean team is committed to improving treatment for people living with cancer. We apply our Dynamic Tumor Targeting Platform to create a portfolio of NDCs designed to selectively attack tumor cells, reduce toxicity by sparing the body's normal cells, and enable therapeutic combinations. Our first platform-generated candidate, CRLX101, is in multiple clinical trials in combination with other cancer treatments, all of which aim to unlock the power of combination therapy. Our second platform-generated candidate, CRLX301, is in a Phase 1/2a clinical trial. For more information, please visit www.ceruleanrx.com.
About Cerulean's Dynamic Tumor Targeting™ Platform
Cerulean's Dynamic Tumor Targeting Platform creates NDCs that are designed to provide safer and more effective cancer treatments. We believe our NDCs concentrate their anti-cancer payloads inside tumors while sparing normal tissue because they are small enough to pass through the "leaky" vasculature present in tumors but are too large to pass through the wall of healthy blood vessels. Once inside tumors, our NDCs enter tumor cells where they slowly release anti-cancer payloads from within the tumor cells.
